IPC: G03B27/14
Filed: 1969-05-12
Abstract: 1,257,994. Sheet feeding apparatus. PITNEY-BOWES Inc. 12 May, 1969 [21 May, 1968], No. 24147/69. Heading B8R. [Also in Division G2]  At the beginning of a copying cycle, rollers 82, 84 feed a copy sheet through charging and exposure stations 86, 56 and at the end of the cycle, rollers 122 fed another sheet from a stack 62 into the nip of rollers 82, 84 ready for the next cycle; a clutch lever 138 selectively applying drive to these two sets of rollers. A drive chain (40, Fig. 2, not shown) continuously drives other feed rollers 18, 20, 32, 34, 88, 90, 98, 100, 106, 108 and a sprocket 132 on the lever 138. Sprocket 138 drives gears 150, 152 also on lever 138. An original, fed in via a plate 16, triggers a switch 192 energizing a solenoid 146 which pivots lever 138 anticlockwise against a spring (142). This brings gear 152 into engagement with gear teeth on roller 84 to feed a copy sheet. When the switch is released by the trailing edge of the original, the solenoid 146 is de-energized, and the lever 138, returned by the spring (142) to engage gear 152 with gear 158, which is mutilated so that it is only driven through one revolution, this being sufficient to drive rollers 120, through gear 124, to position another sheet at rollers 82, 84. Gear 158 is stopped by engagement of a shaft 170 thereof with lever 138. When lever 138 moves to drive roller 84 at the beginning of the next cycle, a spring pressed cam follower (182), engaging a recessed portion 177 (Fig. 3) of gear 158, rotates it slightly to move away the mutilated part. Another shaft (202, Fig. 4, not shown) on gear 158 switches the exposure lamp 42 and charger 86 on and off. Mirrors 46, 54 and lenses 48, 50 (with reflecting surface 52) comprise the optical system. A further switch 196, in parallel with switch 192, is actuated by the copy paper to ensure a full cycle if a short original is used.

Abstract: 1294983 Automatic control of dual stator induction motors RUSTON-BUCYRUS Ltd 5 Aug 1970 [19 Nov 1969] 37708/70 Heading G3R The torque of a dual stator induction motor is automatically maintained at a predetermined value by comparing signals respectively representative of the motor torque and the predetermined value to obtain a control signal, which causes an actuator to change the relative position of the two segments forming the stator. In the described embodiment an adjustable segment 9 is moved relative to a fixed segment 10 by an actuator 2 comprising an electric, hydraulic or pneumatic motor coupled to the segment 9 through an arcuate gear and a pinion, Fig.2 (not shown). Voltage and current transformers 22--25 supply a watts transducer 5 whose DC output signal at terminals 26,27 is directly proportional to the AC power supplied to the motor from the mains 14,15,16. This signal is also linearly related to the motor torque and is supplied to a summing amplifier 3 via members 28,29,31 where it is combined with a reference signal obtained via members 33, 34, 35, the output of amplifier 3 being used to control the actuator 2. The segment 9 is thus adjusted to maintain the torque at the value set by potentiometer 33, adjustment to the point of maximum travel of the segment causing operation of a limit switch 37 which prevents further control by the amplifier 3 in this direction. A similar operation occurs when the segment 9 reaches its zero torque position. Typical torque-speed characteristics are discussed, Fig.3 (not shown).

Abstract: 1297335 Valves S A LEBLANC 28 May 1971 [23 Oct 1970] 17837/71 Heading F2V [Also in Division F4] Supplying gas to a burner at one of two possible output rates, is effected by an electromagnetically actuable compound valve having a single valve member 2 and a relatively larger double valve member 4, 5, the former controlling a low output passage 10, 12, 13, 25, 11, and the latter controlling a high output passage 10, 11. The single and double valve members are interconnected, with lost-motion, by a rod 14 extending from the magnet core 16. In use, closing of a switch 22 results in the core moving over only part of its possible stroke. In consequence, only the single valve member 2 is unseated. Closing of a further switch 23 results in the core moving to the end of its stroke as determined by the engagement of valve member 2 and valve wall 26. During this latter movement, part 5 of the double valve member 4, 5 is unseated first thereby allowing an equalization of pressure across valve part 4. Subsequently, a projection 8 on valve part 5 unseats part 4 with a tilting action. The truncated and flanged shape of the core 16 ensures that it attains one of two positions in dependance upon the voltage applied to the winding 71. An adjustable throttle valve 27 is disposed in the low output passage. In a modification, Fig. 2, not shown, the core 16 may be disposed within a winding which consists of two independently energizable coils (17a, 17b).
