Abstract: 1,020,365. Sheet-delivery apparatus. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT & CIE A.G. Nov. 14, 1962 [Nov. 18, 1961], No. 43046/62. Heading B6H. Papers such as newspapers 51 leaving a printing machine in overlapping formation between bands 48 are delivered in batches of predetermined number to a belt 52 by blades 18 rotating around the axis of a continuously driven shaft 4, the blades being controlled so that each blade moves parallel to itself during the time it is receiving a batch from the bands 48. The blades 18 are fixed at their inner ends to spindles 14 pivoted in the outer ends of arms 12 and carrying cranks 15 having follower rollers 17 spring-urged against a cam surface 20. The arms 12 are fixed to spindles 8 pivoted in discs 6 fixed to the driven shaft 4, the spindles 8 carrying crank arms 9 with follower rollers engaging a cam 11. A depression 46 in the cam 20 causes a blade 18 to move sharply in position to receive the first copy of a new batch, and subsequently the cams 11, 20 control the blade 18 and its arm 20 so that the blade remains parallel to itself whilst the batch is being deposited and moves slightly slower than the speed of rotation of the shaft. Afterwards the blade is caused to move clockwise relatively to the shaft 4 to deposit the batch on the belt 52. Newspapers of half the thickness may be delivered in batches of the same number as has already been considered by moving two cam members 23, 29 into operative position at the stack-forming position, these cams causing the blades 18 to move forwardly at half the original speed during the formation of a stack. The speed of the shaft 4 is adjusted according to the number of copies required per batch. The newspapers are supported at their bottom edges by driven endless bands 44 which pass over bars 45 extending from the belts 48 to the belts 52. Brush rollers 49 adjacent to the stacking position serve to flatten the papers along their folded edges.

Abstract: 1470707 Closed circuit gas turbine plant UNITED TURBINE AB & CO KB 8 Oct 1974 43440/74 Heading F1G A closed circuit gas turbine plant comprises a turbine 30 and compressor 31 contained within a cylindrical casing 10 having domed ends 11, 12, the working fluid being indirectly heated outside the casing. In the arrangement shown, the heater comprises a combustion chamber 23 supplied with air via a rotary regenerator 22, the combustion products discharging over heat exchanger tubes 19 through which the closed circuit gas, e.g. air, hydrogen or helium, passes on its way to turbine 30. Gas leaving the latter passes through a heat exchanger 18, where it gives up heat to gas leaving compressor 31, and thence passes via cooler 20 back to the compressor inlet. Make-up gas may be supplied to the circuit via line 24 from a reservoir arrangement (25), Fig. 1 (not shown). In addition to driving compressor 31 via shaft 32, the turbine 30 provides output power via a hydraulic pump 16 or electric generator disposed at the end of casing 10 remote from heat exchanger 19. In modifications heat exchanger 19 may be heated by gas and/or liquid flowing through ducts 36, 37, e.g. from a nuclear reactor or heat pipe. In a three-shaft arrangement, Figs. 3 and 4 (not shown), an additional pump (46) may be provided to assist pump 16 or to pressurize make-up gas. Nitrogen oxide formation in combustion chamber 23 may be reduced by automatically controlling the air/fuel ratio by recirculating exhaust gases or by controlling the speed of regenerator 22.

Title: Solid-state storage device

Filed: 1974-10-14
Abstract: 1484716 Transistor gating circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 Oct 1974 [17 Oct 1973] 44349/74 Heading H3T [Also in Division G4] The system includes a solid state store and a drive unit which generates a clock chip enable signal CCE and a clock write enable signal CWE on respective outputs. Signal CWE is fed to the store and to a drive element. The drive element also receives signal CCE, and its output is fed to the store. The drive element is so designed that its output passes to a first level in response to a transition to a first state in CCE, irrespective of the state of CWE, and passes to the other level both in response to the occurrence of a transition to the other state in CCE and in response to a transition in a given direction in CWE. The drive unit generates clock chip precharge signal CCP, clock chip enable signal CCE, and, during a write operation, clock write enable signal CWE. In the rest state of the drive element, transistors T1, T3 are on and T2, T4 are off so that the potential S1 on terminal k10, which is connected to the memory, is high. When CCE, which is applied to input k9, becomes high T2, T4 turn on, T1, T3 turn ofi and k10 becomes low. If the signal on input k8 is steady, as during a read operation, or changes from low to high, it has no effect on the circuit, and so when CCE goes low the transistors revert to their initial state and k10 reverts to high, as shown in S1. However, if the signal on k8 has a neagtive-going transition prior to that in CCE, i.e. when a write pulse occurs during CCE as indicated in CWE, the voltage drop is passed via C1, C2, C3 to turn T2 off, with the result that k10 becomes high, as shown in S2. The negative-going transition on k8 causes T1 to turn on for a period approximately equal to R1, C1. Should CCE on k9 become low during this period it has no effect. Thus the positive-going transition on k10 occurs simultaneously with the first negative-going transition to occur in CCE or CWE. The signals CCP and CWE are applied to the store via respective drive elements.
