Title: Improvements relating to telephone systems
IPC: H04Q3/00
Filed: 1925-11-26
Abstract: 266,460. Siemens Bros. & Co., Ltd., and Humphries, H. E. Nov. 26, 1925. Automatic exchange systems.-Clicks due to the current reversal when the called party answers or clears or during a lamp flash busy signal, are minimized by causing the supervisory relay D at a connector or other feed bridge to control the reversing relay RV (which may be slow to operate) with the aid of a third relay CR which is slow to' operate and slow to release, and which on pulling up connects a condenser QC across the calling loop. Relay D on pulling up energizes relay CR which connects up the condenser QC and removes a short-circuit from relay RV which locks up and short-circuits relay CR. If the called party hangs up first, the relapse of relay D removes the short-circuit from relay CR which, since release relay B is still energized, connects up the condenser again and short-circuits relay RV. The relapse of relay RV disconnects relay CR. The invention has the advantage that no ill-effect is produced if the back-bridge relay kicks during impulsing. According to the Provisional Specification, the condenser may be replaced by a resistance or inductance or a combination of the two. Operation of connector. Line relay A repeats the tens digit to magnet VM and relay C in series. At the end of the digit, relay C energizes relay G over vertical springs K1 and the units digit is repeated to the rotary magnet and relay C. Relay G holds up over rotary springs W1 after relay C is energized and falls back on the relapse of relay C at the end of the digit. In the interval between the relapse of these relays the test circuit b1, g1, c2, H is completed. If the line is busy, relay H remains back and the relapse of relay G energizes relay F (2) which sends back busy tone from BB. If it is idle, relay H pulls up and the relapse of relay G sends out ringing current over F (1). When the called party replies, relay F pulls up, locks itself by removing a short-circuit from its winding (2) and completes the loop to the back bridge relay D. which controls the current reversal as described above.

Title: Sheet feeding mechanism
IPC: B65H3/08
Filed: 1965-07-14
Abstract: 1,065,136. Feeding sheets. HARRISINTERTYPE CORPORATION. July 14, 1965 [Nov. 23, 1964], No. 29936/65. Heading B6B. In apparatus for separating sheets from the top of a pile by suction means, and by air-blast means for directing a stream of air to float the sheets, a single control member can operate actuating means which control valves in the suction and compressed air lines whereby the pressures in these lines can be adjusted. The single control means is situated adjacent the platform of the operator. As shown, suckers 16 lift the top sheet of a pile P, suckers 17 forward the sheet between feed rollers 13, and the latter feed the sheet over a feed-board 14 to a printing press 11. The top sheets of the pile are ruffled by air-blasts from nozzles 18, and the top sheet is floated by air-blasts from nozzles 19 during its forward movement by the suckers 17. A single rotary valve 20, Fig. 2 (not shown), controls the connections from a suction line 22 to the suckers 16, 17, and those from a compressed-air line 21 to the nozzles 18, 19, and these lines are connected through pressure control valves 26, 24, respectively, to a pump 80. The valves 24, 26 are in a common body 27. The valve 24 for the compressed-air line 21 has inlet and outlet openings 31, 32, respectively, Fig. 6 (not shown), and a relief passage 36 to atmosphere is closed by a ball 37 engaged by a spring 40 in a plunger 41 which presses against a cam 45 secured to a shaft 70. Rotation of the cam 45 thus controls the pressure on the ball 37, and this controls the pressure of air in the line 21. The valve 26, Fig. 5 (not shown), in the suction line 22 has inlet and outlet openings 51, 52, respectively, to a chamber 53 which communicates with ports 56 to atmosphere when a plunger valve 58 is in a raised position. The valve 58 is urged upwardly by a spring 61 against a cam 61 secured on the same shaft 70 as the cam 45, so that rotation of the cam 61 entirely seals the suction chamber 53, or allows it a controlled outlet to atmosphere. Each valve 24, 26 communicates with a pressure gauge, and each has an adjustable relief valve set to determine initial working pressures in the lines 21, 22. The common shaft 70 extends to a control knob 75 in a position adjacent the platform 75 for the machine operator, and rotation of the shaft also trips switches 84, 85, Figs. 3 and 8 (not shown), which start and stop the motor driving the pump 80.

IPC: G01D5/36
Filed: 1959-09-07
Abstract: 966, 901. Electric selective signalling systems. GRASEBY INSTRUMENTS Ltd. Sept. 7, 1960 [Sept. 7, 1959], No. 30533/59. Heading G4H. In a system for measuring the extent and direction of motion of a uniformly graduated photo-electrically sensed scale in which one part of the scale is imaged on to another part, Fig. 1, the image of the one part being rotated slightly with respect to the second part whereby a moire fringe pattern is produced, the direction of motion of the scale is determined by sensing it twice, the two sensings being so arranged that as a dark line is approaching one sensing point a dark line is receding from the other sensing point. The relative phasing of the two sensings can be achieved either by suitable positioning of two light sources or by suitably adjusting the optical components in the light path. The two light beams could use some optical components in common by using, for example polarised light. In the preferred embodiment the two light beams are turned on alternately, at mains frequency, and a single photo-electric cell is used. Two lamps 12, 13, Fig. 2, are turned on alternately, at mains frequency, and the signals produced by the single photoelectric cell PE Fig. 5 are amplified by triodes V1, V2 which are rendered operative in synchronism with the operation of the lamps by a centre-tapped transformer T. As a result, depending upon the order of occurrence of the pulses from the cell a pulse, in the form of a break in earthing, is transmitted, on one of two leads A and B, this pulse actually occurring when the intensities of illumination of the cell by the two lamps is the same.
