Filotecnica Model 201 Back-Light Screen Projection Slide Rule, Italy c. 1955
1/5
Beschreibung
Anfang der 1950er Jahre entwickelte das für seine Präzisionsgeräte bekannte Unternehmen Filotecnica Salmoiraghi auf der Grundlage der Patente von Abeille und Aquilecchia einen Rechenschieber, der die Skalen auf einen hinterleuchteten Bildschirm projizierte. Diese Lösung ermöglichte, dass ein sehr kompaktes Gerät die gleiche Genauigkeit wie ein traditioneller Rechenschieber von 2,5 Metern Länge erreichte. Bei logarithmischen Taschenrechnern ist die Genauigkeit in der Tat proportional zur Länge. Ziel war es, eine logarithmische Rechenmaschine auf den Markt zu bringen, die billiger ist als eine elektromechanische Rechenmaschine. Dieses Ziel wurde nur teilweise erreicht: Das Gerät ist zwar sehr genau, war aber dennoch zu teuer, da es zum gleichen Preis wie ein gutes Motorrad verkauft wurde, was einem durchschnittlichen Gehalt von zwei Monaten entsprach. Zu teuer also für einzelne Kunden, während Unternehmen es vorzogen, die teurere, aber unschlagbare Olivetti Tetractys zu kaufen. Das Projekt wurde daher nicht weiterverfolgt, und laut einem in der Zeitschrift der Oughtred Society veröffentlichten Artikel wurden nur 5 Stück gebaut. Dies ist eines der 3 bekannten "Überlebenden", ein vierter ist in einem irreparablen Zustand und über den fünften ist nichts bekannt. Dieses Gerät ist in perfektem Zustand, komplett mit einer Anleitung in italienischer Sprache und einem Lederetui, das wahrscheinlich nicht original aus der Fabrik stammt. Die Serien-Nr. 45605 entspricht den Gewohnheiten der Fabrik, die die Produkte in der Reihenfolge des Verlassens der Produktionslinie und nicht nach Serien oder Modellen nummerierte. Die Serien-Nr. erscheint neben den anderen vier als existierend bekannten Geräten auf der Website http:/Iwvwv.rechnerlexikon.de. Dieses Gerät scheint 1955 an das Kommunikationsunternehmen Telettra (eines der wichtigsten Unternehmen der damaligen Zeit) geliefert worden zu sein, weist aber praktisch keine Gebrauchsspuren auf. Werbung für diesen Rechner erschien in den Katalogen von Filotecnica nur in den Jahren 1954 und 1955. Die Firma Filotecnica Salmoiraghi, die 1865 von Ignazio Porro (Erfinder des prismatischen Fernglases) gegründet wurde, war etwa 100 Jahre lang die wichtigste italienische Fabrik für optische und nautische Meß- und Präzisionsinstrumente.

In the early 1950s the company Filotecnica Salmoiraghi, well known for its precision equipment, developed a slide rule that projected the scales onto a backlit screen from the patents of Abeille and Aquilecchia. This solution allowed a very compact device to have the same precision as a traditional slide rule of 2.5 meters. With logarithmic calculators, precision is in fact proportional to length. - The goal was to market a logarithmic calculator cheaper than an electro-mechanical calculator. This aim was only partially achieved: the device is in fact very precise but was still too expensive. At the time of production, it sold for around the same price as a good motorcycle, and was the equivalent of two months’ average salary. It proved too expensive for individual professionals, while companies preferred to buy the more expensive, but tried and tested, Olivetti Tetractys. According to an article published in the journal of the Oughtred Society, the project was discontinued and only five units were built. - This example is one of the three known survivors, a fourth is in irreparable condition and nothing is known about the ?fth. This unit is in excellent condition, complete with instructions in Italian and a probably non-factory leather case. The serial no. 45605 is typical of the factory, which numbered products in order of exit from the production line and not according to the series or model. No. 45605 appears among the four reported surviving instruments on the website http:/Iwvwv.rechnerlexikon.de. This unit appears to have been delivered to the communications company Telettra (one of the most important at the time) in 1955 but shows virtually no signs of use. Advertising for this calculator appears in the Filotecnica catalogs only in the years 1954 and 1955. Filotenica Salmoiraghi, founded in 1865 by lgnazio Porro - the inventor of prismatic binoculars, was the main Italian factory of optical, nautical, measurement and precision instruments for the best part of a century.

Auction conditions
1) The auction is carried out voluntarily under foreign name and on account of the customer.
2) The goods to be sold in the auction can be examined and checked at determined times before the auction – under the full responsibility and risk of the interested client. They will be put up for auction in the condition as they are without any liability for visible or hidden defects as well as for attributes; later claims of any kind cannot be taken into consideration. The descriptions in the catalogue are made to the best of our knowledge, but they are no guaranteed attributes in the sense of § 459 and following BGB. – Information ref. § 26 UStR is assured. – No right of return of any sold item, therefore please use the advantage of the previewing (also by your friends).
3) Normally the bids are increased in steps of 10 % of the initial price with a minimum of € 5.–. The auctioneer can deviate from this regulation in particular cases. The knocking down is done if no higher offer is made after the third repetition of the highest offer and if the limit price has been achieved.
4) The auctioneer can combine numbers, separate them, can offer them out of the sequence or can withdraw them. The bidding is done by showing the bidding number or by a written offer.
5) The auctioneer can refuse an offer; in this case the offer given right before remains binding. In case several persons make the same offer, the knocking down is decided by lot. In case of identical written offers, the computer makes the decision to the benefit of the first offer received. Decisive in this case is the point of time of its entry. If there is a disagreement on a knocking down or if an offer is made in time has been disregarded, the auctioneer can all the same knock down this bid and can follow-up the rights resulting out of this. He can also knock down to the next lowest bid or can start again with the initial bid of this lot.
6) The knocking down is binding. The goods must be immediately paid. The knocking down transfers the risk of possible losses, damages, mistakes to the purchaser. Each bidder buys in his own name and for his own account.
7) A premium of 21.8% plus 3% Live transaction fee has to be paid on the knocking down price. 16% tax has to be paid on the surcharge, i.e. the total surcharge amounts to 28.77%. The entire amount, which has to be paid by the purchaser, is immediately due and has either to be settled in cash, wire transfer or by guaranteed bank draft. In case of an acquisition by submittance of a written order, the payment has to be settled within 8 days after the invoice date.
8) The goods become the property of the purchaser only after the complete payment. The objects will only be delivered if the payment has been settled. Otherwise the goods are still the property of the consigner until complete payment. In case a payment does not reach the auctioneer in due time, the purchaser is liable without reminder for all resulting losses. Also without proof of a loss the interest for delay at the bank usual rate can be charged.
9) In case the payment is not settled in time or the objects are not taken, the auctioneer has the right either to demand the performance of the contract of purchase or can claim damages due to the non-performance. Independent from the above the auctioneer can also put this object for auction in one of the next auctions on cost of the purchaser. For the resale in the auction the bidder is treated as supplier and has to pay the corresponding order commission as well as the tax to be paid on it. All transportation and storing costs as well as possible charges for the employment of additional workers, which result in connection with the above, will be deducted from the net profits. The remaining profit will be balanced on the date of the actual inpayment with the claim for damages acc. to § 367 BGB.
10) The handing over of the objects bought in the auction is done at any time during and after the auction against presentation of the receipt. Invoices issued immediately after the auction are subject to the right of verification and possible corrections: errors excepted.
Bidders who are present at the auction must arrange the pick-up on the day of the auction. Otherwise the objects will be stored on account and risk of the purchaser without any further notice. The auctioneer does not bear the risk of storing.
11) Each shipment is carried out on the account and risk of the purchaser. Insurance possible on request.
12) Bidder orders are handled with great care; a guarantee for its setting up for auction can only be ensured if the written bidding order has reached the auctioneer latest at 12:00 am (noon) two days before the auction. The bidders unknown to the auctioneer are kindly asked to provide a satisfactory security before the auction.
13) The legal relation is based on the German law. Place of performance and legal venue for the mutual trade business is Cologne.
14) The visitor accepts the above conditions explicitly by his participation in the auction or by his offer.
