IPC: F15C3/02
Filed: 1960-08-12
Abstract: 951,789. Valves. ELEKTRONISCHE RECHENMASCHINEN-WISSENSCHAFTLICHER INDUSTRIEBETRIEB-KARLMARX-STADT. Aug. 12, 1960, No. 27994/60. Heading F2V. [Also in Division G4] A binary series-mode fluid-pressure adder comprises And gates 18-21, and Or gate 22, an Exclusive Or gate 12 and a shift register 59 for temporarily storing a carry signal. An input carry signal is applied from the shift register 59 on a line 43 as digit input signals of the two numbers to be added are applied on lines 44, 45. If only one input signal is received, this is passed by the Or gate 22 and the Exclusive Or gate 12 and through an Or gate 10, 11 to the output line 79. If two input signals are present, one of the And gates 18-20 produces an output signal which is passed to a line 60 as a carry output signal, and also to the Exclusive Or gate 12 which however does not produce an output as it also receives a signal from the Or gate 22. Thus no signal is passed to the output line 79. If three input signals are received, the And gate 21 produces a signal which is passed through the Or gate 10, 11 to the output line 79 and the And gates 18-20 produce a signal which is passed to the carry output line 60. Shift register.-When a carry signal is received on line 60, the member 13 is momentarily actuated so as to allow fluid to pass through lines 64 and RL to a reservoir R2 and the bi-stable device 14 is set to its On condition. A solenoid M is then energized to actuate a member 17 so as to connect a pressurized line 61 to a line 65 and so produce an input signal on a line 70 to the next stage, the device 14 being in the On condition. This input signal temporarily actuates the member 15 and sets the bi-stable device 16 to its On condition. When the magnet M is de-energized, pressure is applied from line 61 to line 62 and passed to the output line 43.

Title: Improvements in or relating to sheet folding machines
IPC: D06F89/00
Filed: 1957-09-05
Abstract: 843,659. Folding sheets &c. ARMSTRONG & CO. Ltd., J., and SMITH, J. Nov. 28, 1958 [Sept. 5, 1957], No. 28085/57. Class 42 (2). A machine for folding bed-sheets &c. comprises a belt conveyer 4, Fig. 1, on which the sheets are fed in succession so that they hang down on each side of the belt, and means for holding back the forward edge of each sheet so that, by the conveying action of the belt, that edge becomes progressively doubled back, and for subsequently releasing that edge so that the doubled sheet is thereafter conveyed by the belt while still hanging down on each side thereof. Sheets delivered by a calender 2 are conveyed by narrow belts 3, 4, supported on plates 44, 45. The forward edge of a sheet is guided by fixed guide members 12, Fig. 4, between upper and lower grippers 7, 10 carried by bridge-shaped members 5, 6 rotatable about an axis X-X. Member 6 is frictionally braked at 25, 26, while member 5 is connected by a trunnion 15 to a sprocket 19 engaging a chain 20 connected at one end to the piston-rod 21 of a pneumatic cylinder 22, Fig. 1, and at the other end to a return-spring 23. When the second of two electric switches 39, 40 is closed by the forward edge of the sheet, a solenoid is energized and compressed air is supplied to cylinder 22. Member 5 is thereby swung to the dotted line position, Fig. 1; firstly it grips the edge of the sheet against gripper 7 and then carries member 6 with it, thus folding back the leading edge of the sheet. Switch 40 is opened, but a pneumatically-operated holding switch maintains the circuit. When the trailing edge of the sheet passes switch 39 the latter opens, the circuit is broken, and cylinder 22 is exhausted. Member 5 thereupon is swung back to the full-line position; firstly it separates the grippers 7, 10, releasing the doubled-back portion of sheet which falls into the portion on the belt 4; thereafter a flange 11 on member 5 engages member 6 to carry the latter back with it. The doubled sheet proceeds along belt 4 to a second transverse-folding mechanism similar to the first. The twice transversely-folded sheet is delivered on to a shoe 13 hanging down on each side thereof whence it can be removed by hand again doubled by a longitudinal fold. A cover. 46 carries idler rollers 47 which press against belt 3 to provide a grip for the sheet. The belts may each comprise a single belt, or a number of narrow belts side - by - side which may consist of wires or chains. The air cylinders may be replaced by hydraulic cylinders or solenoids.
