Patent GB-910839-A (GB)
Title: Improved apparatus for filling containers with liquid
Inventor: BENNETT NORMAN JAMES HERBERT
IPC: B65B43/60
Filed: 1959-12-29
Abstract: 910,839. Fluid-pressure servomotor-control systems. VICKERS RUWOLT PROPRIETARY Ltd. Dec. 29, 1959, No. 44114/59. Class 135. [Also in Group XVII] An apparatus of the rotary turret-type for filling containers 43 with liquid such as beer, includes means for maintaining the air pressure in each container 43, during filling, equal to the gas pressure above a liquid supply in a central distributing tank 22, thereby insuring that the flow of liquid from the distributing tank 22 to each container 43 is due to the hydrostatic pressure only. An air reservoir 21 has a pipe 52 supplying air to each container 43. A differential pressure transmitter 93 is connected to the air reservoir 21 by a pipe 98 and to the gas space above the liquid-distributing tank 22 by a pipe 97. The differential pressure transmitter 93 and a pressure-controlling instrument 92, each receive a uniform controlled air pressure from an air regulator 96, and are interconnected by a pipe 99. When a container 43 reaches its filling position, air flows from the reservoir 21, through pipe 52, into the container, and this causes a momentary decrease in the air pressure in reservoir 21. The resulting pressure difference in pipes 97 and 98 is sensed by the differential pressure transmitter 93 and a pneumatic impulse proportional to this difference is relayed from the transmitter 93, through pipe 99, to the pressure controller 92 which compares the impulse with a set pointer so that a second pneumatic impulse is sent from the controller 92, through pipes 102 and 104 to a vent valve 103 and an air supply valve 91 respectively. This second pneumatic impulse causes a vent valve 103 to close partially or completely, thereby restricting or preventing further escape of air from the reservoir 21 through this vent, and also permits more air to be admitted through the supply valve 91 with the result that the pressure inside the air reservoir 21 increases to the required value. When the container 43 starts to fill, the air pressure in the container increases and back pressure occurs along pipe line 52, to the reservoir 21 to cause a pressure difference in pipes 97 and 98. This difference causes the valve 103 to open partially or completely to exhaust air from the reservoir 21 and caused valve 91 to close partially or completely to restrict or prevent the entrance of air to the reservoir 21.

Filed: 1975-10-31
Abstract: 1492127 Operating railway brakes WESTINGHOUSE AIR BRAKE CO 31 Oct 1975 [6 Nov 1974] 45550/75 Heading F2E Rotation of shaft 22 by a hand-wheel 24 serves to rotate a winding drum 38 for brake operating chain 28 by way of a sleeve 44 screwed to the shaft at 46 and having an eccentric portion 43. The latter causes gyration of a pinion 42 meshing with a ring gear 48 secured to the drum so rotating the latter. Reverse movement of the shaft during brake application is prevented by ratchet 50 which is held between clutch surfaces on the sleeve 44 and a shaft collar 54. The brakes may however be gradually released by rotating shaft 22 in the opposite direction so screwing sleeve 44 away from the ratchet and allowing the chain to pay out under its own tension; this tension causes the sleeve 44 to screw back again into clutching engagement with the ratchet to limit the chain movement. For full brake release a lever 78 is rotated to move a pawl 70 out of engagement with a release wheel 62 the latter having a radial flange 80 formed with notches 84 which receive pins 86 secured to pinion 42. During brake application, pawl 70 holds the release wheel relative to the housing and its withdrawal permits the wheel and winding drum to rotate together under chain tension relative to the shaft. The notches on the release wheel which receive pawl 70 are so shaped that rotation of the handwheel in the wrong sense imparts a bobbing motion to lever 78. The numbers of teeth on the pinion and gear ring are specified for alternative applications. Movement of the winding drum may be limited by a stop; if not, the chain extends completely through the housing and is secured to part of the rail car.

Abstract: 1,274,708. Stop-on-signal receivers; calling arrangements; transistor sawtooth generators. SVENSKA RADIO A.B. 17 Sept., 1969 [20 Sept., 1968], No. 45919/69. Headings H3Q, H3T and H4L. An arrangement for automatically tuning a receiver comprises a tuning unit, a scanning generator arranged to control the tuning unit to cause it periodically to scan through a predetermined frequency interval, and identifying means arranged to respond to a predetermined identification signal received through the tuning unit to stop the scanning, in which there are control means arranged to respond to signals above a predetermined strength received through the tuning unit to cause the rate of scanning of the interval to decrease during such signals. In a receiver comprising a tuning unit A, intermediate frequency amplifier M, detector and discriminator D+F, identifying means I, e.g. a band-pass filter respond to the identifying signals. A scanning generator comprising a double basediode TR1, capacitor C1 and transistor TR2, comprising a constant current generator, delivers a periodical sawtooth scanning voltage of high linearity, which is supplied via an emitter-follower TR3 to point X where it is added to a "slowing" control voltage amplified by field-effect transistor TR4. The combined voltage is applied to tuning unit A. Transistors TR5, TR6 form together a trigger device which, upon reception of a "stopping" control signal generated in identifying means I, cuts off transistor TR2 and therewith the current supply to the scanning generator whereby scanning is stopped.
