Title: Document copying machine
IPC: G03B27/50
Filed: 1973-04-09
Abstract: 1430155 Photo-copying machines W ZINDLER [trading as LUMOPRINT ZINDLER KG] 9 April 1973 [20 April 1972] 16947/73 Heading G2A A copying machine for producing a copy or copies from an original, comprises a reciprocally movable carriage 23 for supporting an original carriage drive means having an endless circulating chain 30, means for uncoupling the carriage from the drive at end positions of its reciprocating stroke, and control means actuated by elements, fixed to the chain, as a result of further movement of the chain after the carriage is uncoupled for controlling the feeding of copy sheets through the machine. The carriage 23 is driven on rails 22 over a scanning aperture 24. The light is directed along a light tunnel 25, 26 to an exposure aperture 10 for the copy material. The carriage has a slide block 34 in which is mounted on rails 37, 38 a guide 35 having a vertical slot 36. The length of  the slot is greater than the distance between the horizontal sections of the drive chain 30 which passes around sprockets 31, 33. A pin 41 carried by the chain is received in the slot 36 and, when the guide is coupled to the block, moves the carriage reciprocally along the rails. The guide 35 is coupled to the block 34 by engaging one of two spring-biased levers 42, 43 pivotally mounted at 44 and 45 respectively. When the carriage reaches one end of its stroke an uncoupling key 56 engages-lever 43 pivoting it out of engagement with guide 35. Thus the carriage stops and the guide moves along rails 37, 38 as the pin 41-is is carried by the chain 30 around sprocket wheel 32. A similar uncoupling key 57 is provided at the other end of the carriage stroke to uncouple lever 42. At the start of a copying cycle a motor drives the chain, however the carriage is at one end of its stroke and is therefore uncoupled. The chain also carries two pins 58, 59 and as pin 58 passes round sprocket 32 it engages cams 60, 61 on a driving disc 33 mounted coaxially with sprocket 32. Pin 59 projects from the chain in the opposite direction and actuates two switches which switch a charging device 9 and light source into the circuit. The pin 58, and also pin 41 rotate the disc 33, which rotates drive-shaft 69 A gear-wheel 79, mounted on shaft 69, rotates and drives a chain to rotate roller 82 and withdraw a sheet of copy paper from the cassette 4 and feed it to rollers 6. The copy sheet is then fed past an exposure station 10 in synchronism with the movement of the carriage, which is recoupled to the drive, and hence the movement of the original past the scanning aperture 24. Several copies of a single original may be produced by setting a disc 109, Fig. 6, which prevents a stop entering the path of movement of the carriage until the selected number of copies has been made. When the stop is contacted by the carriage it stops the motor which drives the chain.

Abstract: 642,490. Automatic tension control systems. GENERAL ELECTRIC CO., Ltd., and DALE, S. H. June 24, 1948, No. 17048. [Class 38 (iv)] [Also in Group XXXVII] In strip winding apparatus, the material is supported in a loop between two rollers and forms, with a fixed electrode, a capacitance which comprises one arm of an A.C. bridge; change in strip tension alters the position of the loop and consequently the balance of the bridge, the output of which is used to correctively control the speed of the winding motor. As shown, the strip 5 of conductive material is wound on roller 2 by motor.4 supplied from generator 8. A capacitance, formed between the plate 11 and material 5 or between two plates capacitatively coupled to the loop (not shown), is inserted in the A.C. bridge 12, the output of which is amplified by valve 17 and applied to the grids 27, 28 of the valves 29, 30. The anodes of the latter are supplied with A.C. in phase opposition by transformer 45 and valves 29, 30 thereby constitute a phase-sensitive amplifier. The D.C. potentials developed across resistors 41, 42 are dependent upon the phase and amplitude of the bridge output and are applied to the grids 47, 50 of the triodes which energize the armatures of motors 56, 55 which are mechanically coupled together and have opposed drives. The tapping of the field-adjusting potentiometer 62 of generator 8 is carried on the common shaft of motors 55, 56 and is positioned in accordance with the output of bridge 12 so as to adjust the speed of winder 6 and consequently regulate the strip tension. Where strip 5 is a non-conductor the loop may support a member which forms a capacitor with a fixed electrode.

Title: Improvements relating to weighing apparatus and cash recorders
IPC: G01G19/41
Filed: 1921-06-22
Abstract: 165,723. Schember, K., and Joksch, R. July 3, 1920, [Convention date]. Sliding-weight apparatus.-The device described in Specification 146,089 for adjusting the poise of a steelyard is moved indirectly by means of a hand-lever, a key. a crank, or the like, and is used in combination with apparatus for indicating and printing the weight of the goods, the kind of goods and their cost. Other indications such as the number of articles, packing number, and date may be provided for. The printing operation cannot be performed unless an exact weighing has been made and the device for indicating the kind of goods or the cost has also been set. Fig. 1 shows the salesman's side of the apparatus. The hand-levers 20 are adjusted to effect the weighing and the hand-levers 41 are set according to the kind of goods and the cost of same. The mechanism in connection with each hand-lever 20 is similar and is shown in Fig. 4. The hand-lever 20 is coupled by a link 21 to the poise adjuster 17 which moves its .poise 15 along the steelyard 11 in the manner described in Specification 146,089. The poise-adjuster carries a spring-mounted roller 18 engaging notches in the guide-bar 16 to assist in positioning the poiseadjuster. The hand-lever 20 also actuates, by means of a link 25, an indicating sector 29 for the customer's side of the machine, and a type sector 28. A counter 23 adds up the successive weights. The hand-levers 41 similarly operate indicating sectors and type sectors positioned alongside the sectors 28, 29. Adding mechanism of ordinary construction is also actuated by the hand-levers 41. A steelyard poise operated by a hand-wheel 39, Fig. 1, is provided to balance the tare. Printed records, apparatus for giving.-After setting the hand-levers 20, 41, the printing mechanism is operated by rotating a handle 64, Fig. 1, secured to a shaft 59, Fig. 4. Cams 60, 61, 62 then effect the following operations, (1) press a printing roller 46 towards the type sectors 28 to print on a paper strip 49<1> passing round the printing roller from a drum 49, (2) rotate the printing roller so as to feed the paper strip forward, and (3) actuate a lever 55 carrying a knife 56 to cut off the printed strip which then falls down a delivery shoot 65<1>. A fourth cam 63 rocks a lever 66 so as to encircle a projection 67 on the steelyard unless the steelyard is out of equilibrium in which case the cam 63 and the printing handle 64 are prevented from rotating and a printed record cannot be obtained. To prevent a printed record of the weight being obtained before the levers 41 have been set, a pin 72 is arranged across the actuating arms of the printing segments of the " kind of goods " and cost mechanisms. The pin 72 is connected by linkage 71, 70 to a catch 69 engaging the printing handle 64. When one of the levers 41 is set, the pin 72 is moved and liberates the catch 69. After a printing operation, the printing handle 64 in completing its rotation actuates a bar so as to push back the hand-levers 20, 41 to their zero positions.
