Title: Sheet feeding mechanism having corner and centre stack restrainers
IPC: B65H3/34
Filed: 1963-12-06
Abstract: 999,935. Feeding Sheets. A. B. DICK CO. Dec. 6, 1963 [May 1, 1963], No. 48316/63. Heading B6B. In a sheet-feeding apparatus comprising means for separating the topmost sheet from a stack, the sheets in the stack are restrained at the front corners by horizontal flanges on vertically slidable members, and all the sheets, except the topmost one, are restrained from forward movement by a restraining member positioned in front of the stack adjacent the centre thereof. As described, the apparatus is associated with a duplicator, or like printing machine, the stack of sheets being supported on a table which is raised automatically as the stack is depleted, and the sheets are separated from the stack by a pair of friction rollers spaced apart on a non-rectangular drive shaft. Adjacent the front of the stack and secured to the frame of the duplicator is a vertical plate 52, Fig. 4, on which are mounted two members 36 which have bent-over lips adapted to rest on the front comers of the stack, and the centre restraining member 64. The corner members 36 are substantially as described in Specification 873,747. The member 64 comprises a vertical blade which is slotted vertically at 82, and has a pin connection with a horizontal slot 54 in the plate 52. The lower end 72 of the member 64 has pins 74 which engage a horizontal slot 68 in an adjusting plate 66, which is on the opposite side of the plate 52 the latter having a wide horizontal slot 70 to allow the pins 74 to pass freely therethrough. The adjusting plate 66 is guided for vertical movement on the plate 52 by a pin-and-slot connection 90, 88, and has two inclined camming slots 102 which are engaged by pins 100 on a plate member 94 provided with a handle 96 and supported on the plate 52 by the pins 100 which engage horizontal slots 98 in the plate 52. Thus, when the plate 94 is moved horizontally, the centre restraining member 64 is moved vertically, and the top edge can be adjusted to hold back all the sheets but the topmost one during the separating action. The two comer members 36 have pin connection with the slot 54 to allow limited vertical movement, and they rest under gravity on the front corners of the stack; their lips are slotted at 46 for sliding engagement with side guides for the stack of sheets. In a modification, the centre restraining member 64a, Fig. 6, is slidable vertically on a carrier plate 116 which has lugs 120 engaging horizontal slots in the main fired plate 52a. The member 64a has a vertical gear rack 132 secured thereto and engaged by an elongated pinion 140 and a gear rack 142 engaging the pinion 140 can be moved by screw-thread means operable by a knob 152 to cause vertical adjustment of the centre restraining member 64a.

Title: A control system for changing the control range of autopilot servos
Inventor: MADELUNG GERO
IPC: B64C29/00
Filed: 1963-12-10
Abstract: 1,020,185. Automatic control of aircraft. MESSERSCHMITT A. G. Dec.10, 1963, No. 48681/63. Heading G3R. The range of movement of an aircraft autopilot servomotor is automatically extended if the servomotor operates a limit switch and electric signals indicate abnormal operation of the aircraft power units. In Fig. 1, signals representing differences in thrust or power between corresponding propulsion units 1, 3 and 2, 4 on opposite sides of a VTOL aircraft, are developed by units 5 and 6 and added together at 7. If the resultant signal from unit 7 exceeds a predetermined positive or negative value, indicating an unbalanced thrust in one sense or the other, the signal passes through a limiter 8 or 9. If, in an attempt to counter this unbalance, a hydraulic servomotor 18 of the roll rate control section of an autopilot has reached a corresponding limit position by engagement with a stop member 12, a switch 10 or 11 is closed to cause the unbalance signal to energize a relay 16 so that a motor 14 turns stop member 12 out of engagement to permit full travel of servomotor 8. A signal representing the difference between the two differences in thrust of the two pairs of propulsion units is derived by a unit 15 and, when this signal falls below a predetermined value, a relay 17 de-energizes to operate motor 14 so that stop member 12 is restored to its effective position. Application to servomotors in the yaw and pitch control channels and parallel circuits to improve reliability, are referred to.

Abstract: 1,161,335. Sampling granular material. HENRY SIMON Ltd. 30 Oct., 1967 [1 Nov., 1966], No. 48815/66. Heading B8N. An apparatus for sampling granular material comprises a screw means 14 for feeding material past a sample testing device 21, 22 in a duct 13 and means 15 downstream of the device for restraining the flow of material in the duct so that material is continuously present in a predetermined quantity at the testing device. As shown the restraining means is formed by a curved duct section 15 which causes the material to fill the duct completely at the position of the testing device, e.g. a microwave transmitting device. In alternative arrangements the restraining means may be formed by a spring or gravity loaded flap mounted on the open end of a horizontal duct or by a flexible diaphragm having cuts to form, in effect, flexible restraining flaps. The feed screw may be replaced by a piston device and baffles may be fitted in the sampling hopper 10.

Title: Two-phase thermosyphons
IPC: F28D15/02
Filed: 1975-11-14
Abstract: 1532627 Thermosyphons INDUSTRY SECRETARY OF STATE FOR 14 Nov 1975 [15 Nov 1974] 49277/74 Headings F4U and F4S A thermosyphon comprises a vessel 1 having an upper condenser portion and a lower evaporator portion, an annular condenser sump 11 and a conduit 7 interconnecting the condenser sump and the evaporator portion. The conduit 7 includes an auxiliary finned condenser 10 in an inclined portion 9. In operation of the device, condensate collects in the sump 11 so sealing both ends of the conduit 7. The vapour trapped in the conduit 7 is condensed by the condenser 10, causing condensate 10 to be drawn up from the sump 11 and from the evaporator. As soon as condensate reaches the upper end of the inclined portion 9, syphonic action causes all the liquid present in conduit 7 and sump 11 to flow down into the evaporator. In a further embodiment (Fig. 2, not shown), the U-shaped portion 8 of the conduit 7 extends into the evaporator section, and a secondary conduit (12) interconnects the auxiliary condenser 10 with the condenser portion. In this form, the thermosyphons may be individually controlled, and may therefore be incorporated in a bank (Fig. 5, not shown). In other embodiments, the conduit (12) may be replaced by a small aperture; the U-shaped portion 8 may be replaced by a portion extending from the condenser 10 downwards into the sump 11; or the conduit 7 may be small enough in diameter for plugs of liquid to flow by capillary forces. Further, a tube (22, Fig. 4) having a slot (23) may surround the conduit 7 in the sump 11, the top edge of the slot being lower than the end of conduit 7. In this case, when the surface of the condensate falls below the bottom of the conduit 7, vapour is drawn into the conduit 7 from the top end of the tube (22). This prevents any inert gas present in the thermosyphon from entering the tube 7. An auxiliary sump (Fig.. 3, not shown), may surround the end of the conduit 7 in the evaporator section.
