Title: Arrangement for the preparation of printing orders
IPC: G03D15/00
Filed: 1971-10-01
Abstract: 1321330 Printing orders for film strips AGFA-GEVAERT AG 1 Oct 1971 [2 Oct 1970] 45826/71 Heading G2C Long strips of negatives are cut into suitable lengths, and strips of prints are cut into individual prints, the negatives and prints then being  assembled together and packed into a wallet, the complete operation being co-ordinated by a control means. The operations are carried out on a work table 1 and controlled by an operator on a seat 2. The prints come in the form of a roll, which is unwound by a device 9 and fed to a cutting apparatus 8. This operates in accordance with scannable marks on the reverse side, and after a start pulse, continues to cut the roll into individual prints until a further mark is sensed, which stops the cutting device. A sorting device 10 then sorts the prints into satisfactory and unsatisfactory pictures on the basis of further marks. The poor pictures can be reprinted using different correction values. The negatives, which have been secured together to form a single long strip, are now cut up into lengths suitable for packing by a cutter 3, the cutter being controlled by edge notches or perforations in the film. The cut film strips are discharged and stacked at a station 4 and inserted into wallets from a magazine 5. The film strips from the left hand end of the table and the cut prints from the right hand end are now brought together and placed in an order wallet supplied from a magazine 6. The wallet is now passed through a slot 7 to a stamping machine below the table. Various data or information may have been stamped previously on the wallet, which is read automatically at slot 7 and passed to a computer. Other data regarding, for example, date, price, size, and so on can be fed to the computer by means of a keyboard 11, and can then be stamped on to the wallet.

Abstract: 471,711. Knibting-machines. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, JOHANSSON, A., and GOMERSALL, B. Dec. 3, 1936, No. 33227. [Class 74 (ii)] A knitting-machine driven, by a commutator motor is provided with means whereby the speed can be automatically decreased for narrowing or during plating, while the normal speed can be regulated by hand. The speed regulation is obtained by moving the brush ring, and the means comprises an operating motor 8 which drives a chain wheel 5 and thereby the geared ring 1 supporting the brushes of the main motor as well as a contact drum 14. The contact drum 14 has contacts 14<1> engaged by fixed brushes 15 and brushes 16 movable circumferentially of drum 14 by the usual speed-control rod 19. As shown in Fig. 2, stops 21 on a pattern chain 20 operate a switch 23, 26 to energize a solenoid 30 to move switches 33, 34 to supply current to the operating motor 8 so that the ring 1 is moved to reduce the speed of the knitting-machine. A stop 9 upon a wheel 6 rotating with the chain wheel 5 is also brought under the end 10 of a switch 12 to break the supply of current to the motor 8, and the drum 14 is rotated to a position indicated by I, Fig. 2. Upon the stop 21 passing from beneath the end of the switch member 23, and due to the rotation of the drum 14, current passes via the lowest contact 14<1> and uppermost contact 14<1> to a second solenoid 31, so that the motor 8 is driven in opposite direction to speed up the knitting machine. Movement of the brushes 16 by the rod 19 permits energizing of either of the solenoids 30, 31 and causes rotation of the motor 8 in either desired direction. In another arrangement, separate pattern chains operative upon switches are provided for reducing the machine speed during fashioning and during plating.

Filed: 1970-10-08
Abstract: 1321128 Semi-conductor devices TRW Inc 8 Oct 1970 [14 Nov 1969] 47995/70 Heading H1K The electrical characteristics of an alloyed junction diode are improved by subjecting the completed diode to a heat treatment involving maintaining it at a first temperature above the alloy eutectic temperature for a predetermined time, changing the temperature to a second level, also above the eutectic temperature, and maintaining this temperature for a second predetermined time, and then cooling the diode to below the eutectic temperature. For a Si diode having its PN junction formed by alloying Al thereto the temperatures are all preferably in the range 800-1100 C. The differences between the two temperatures may vary from as little as C. up to 30 C., and the temperature change may be an increase or a decrease. Additional temperature changes may also be carried out before the final cooling, and a number of exemplary heating programmes are disclosed in the Specification. In a modification of the method the temperature, instead of being changed sharply between maintained levels, is varied continuously between two levels above the eutectic temperature before being lowered below the eutectic temperature. Temperature control is preferably achieved by varying the rate at which nitrogen flows across the wafers containing the diodes while heating is carried out.
