Title: Improvements in radial pumps
IPC: F04B23/10
Filed: 1938-12-21
Abstract: 524,384. Revolving-cylinder pumps. AIRCRAFT HYDRAULIC APPLIANCES, Ltd., WYLIE, H. N., and GROVES, W. R. Dec. 21, 1938, Nos. 37140/38 and 19877/39. [Class 102 (i)] [Also in Group XXXIV] In a pump of the kind comprising radial cylinders rotating in an eccentric track-ring, the cylinder-assembly is arranged to act as an impeller for centrifuging the working fluid from an inlet to an outlet disposed relatively near to and remote from the axis, the outlet having branches communicating with the cylinderassembly and an external cooling-circuit. The construction ensures adequate cooling of the pump and, when the pump is employed for lubricants, also ensures lubrication of the working parts. The pump shown in Figs. 1 and 2 is similar to that described in Specification 524,199 and comprises a block of cylinders 5 revoluble on a stationary spindle 7 and driven by a shaft 8. Pistons 6 in the cylinders have slippers 11, described below, engaging a trackring 3 which can rock on a knife-edge 2B on the casing 1 and is urged by a spring 4 into the position of maximum eccentricity in relation to the spindle. The part 1B to 1C of the casing is concentric to the knife-edge and acts as a guide for the track-ring. Ducts 7B, 7A in the spindle open into grooves 7C, 7D which are separated by lands 7E, 7F and communicate with ports 5B in the cylinders when the cylinder-block rotates. The casing 1 and duct 7B are provided with an inlet 1A and an outlet 10, and the casing is formed with a divergent passage 1D communicating through a duct 1E with the groove 7C. The duct 1E communicates also through a branch 1F and a valve or constriction with the liquid-source. The cylinder-block acts as a centrifugal impeller and forms a first-stage low-pressure pump, part of the output being fed to the cylinders, these constituting with the pistons a high-pressure pump. When the pump is idling, the centrifugal liquid maintains a cooling flow through the pump. The cylinders may be provided with vanes or webs. The trackring swings under control of the output pressure to vary the eccentricity of the track-ring and consequently the stroke of the pistons. Each slipper 11, Figs. 1 and 2, has pads engaging the channelled track-rings 3, and a bridge 12 which can rock with line-contact on a convex surface 6A at the bottom of a slot in the head of the piston 6, the rocking movement being resisted by a retaining wire 11B which passes through lugs 11A on the slipper, and a hole in the piston. The pads act as Michell bearings, the parts ahead of the web 12 in the running direction being somewhat longer than the parts at the rear. In an alternative pump-construction, Fig. 5 (not shown), the track-ring is formed with a divergent channel through which the centrifugal liquid flows to the inlet-duct of the cylinders. The track-ring rocks on a pin mounted in the casing and formed with an outlet-passage.

Title: Densitometer
IPC: G01N21/25
Filed: 1965-09-01
Abstract: 1,096,416. Selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 1, 1965 [Sept. 23, 1964], No. 37316/65. Heading G4H. [Also in Division G1] The optical density of a film is measured by shining light through it and an optical wedge in series, sequentially sampling the light passed at points along the wedge, applying the resulting signals to a level detector to produce pulses so long as the light passed is above a minimum level and making the pulses count down a preset counter to provide a digital indication of the film sensitivity. The sampling may be effected by a number of light guides 22-1 . . . 22-n, Fig. 2, each leading to a photoconductor 24-1 . . . 24-n. The photo-conductor outputs are fed to gates 26-1 . . . 26-n opened in sequence by a ramp signal from a generator 28. Whenever the signal passed by a gate 26 is greater than the signal corresponding to light passed by the dark end 14-2 of the wedge 14 alone, the level detector sends a pulse to counter 18 to reduce the count by one. In a preferred embodiment, Fig. 3 (not shown) the light guides and photo-conductors are replaced by a semi-conductor n-type body with a plurality of p-type dots embedded in it. When a ramp signal is applied to such a body the signal produced is similar to the output from the gates 26-1 . . . 26-n. To measure density in three colours, three similar systems are used each provided with a different colour filter.

Title: Improvements in or relating to torque measuring means
IPC: G01L3/14
Filed: 1957-11-29
Abstract: 880,008. Fluid-pressure servomotor control systems. BELOIT IRON WORKS. Nov. 29, 1957 [Dec. 7, 1956], No. 37324/57. Class 135. [Also in Group XIX] A torque-indicating device comprises a rotatable shaft 21 arranged for limited axial movement, means 14, 16 for producing an axial thrust in the shaft 21 proportional to the torque, a chamber 120 containing fluid under pressure and a valve 191 operative to control the discharge of fluid from the chamber to the atmosphere the shaft 21 being maintained in a position intermediate of its limits of axial movement by the pressure fluid, and the fluid pressure being indicated on a gauge 154. As shown, the torque to be measured is transmitted through gears 16, 14 having helically formed teeth and a spur gear 54, and is converted by the use of gears 14, 16 into a corresponding axial thrust acting to the right on the shaft 21. The shaft is supported for movement in this direction only by a fixed thrust bearing 44 and an axially movable double thrust bearing 88 connected to a non-rotatable diaphragm assembly 124 in a cylinder 114. This cylinder can be connected by means of a valve assembly 136, Fig. 2, not shown, to a pressure source, or to the atmosphere through the valve 191, and the pressure therein is indicated on the gauge 154. In operation, if the axial thrust due to the torque being transmitted is greater than the thrust developed by the air in the cylinder 114, then the diaphragm assembly 124 moves to the right and opens the valve 136 to the pressure supply until the thrusts are equalized. If the reverse is true, the diaphragm assembly 124 moves to the left and the cylinder is opened to atmosphere, the connection to the supply remaining closed until the thrusts are equalized.

Abstract: 1,074,778. Circuits employing bi-stable magnetic elements. WESTERN ELECTRIC CO. Inc. Sept. 17, 1964 [Sept. 24, 1963], No. 37964/64. Heading H3B. Word conductors of a data store are associated with non-linear inductive elements which present a high impedance to small shuttle pulses but a low impedance to access pulses. Word conductors (12) of a multiplane memory are selected by means of a coincident-current toroidal core access matrix. Each word conductor also threads a small toroidal core (25). Cores (15) in the same row and column of the access matrix as the selected access core receive half-select currents to produce small shuttle currents in the associated word conductors. These currents are insufficient to saturate cores (15) and are suppressed, whereas a full access current saturates cores (15) and is substantially unattenuated. In a wire memory element store in which the word conductors are flat strips each linking an access core and passing around a plane of the memory, the individual suppressor cores are replaced by bar of magnetic material common to all the word conductors of a memory plane. All the cores of the access matrix are threaded by a biasing winding to maintain the cores in a particular remanent state.
