Title: Improvements in or relating to Circuit Earthing Devices.
Inventor: LONGHI CARLO
IPC: F02P7/00
Filed: 1917-07-31
Abstract: 120,224. Longhi, C. July 31, 1917. Relative arrangements.-For protecting three-phase circuits and apparatus against transient high-voltage phenomena, such as surges and lightning strokes, a rotary make-andbreak earthing device is employed driven continuously in synchronism with the currents of the system and adapted at each revolution to earth, momentarily, the several phases of the circuit in succession at the zero point of the voltage curve of each circuit so as to discharge, to earth, excessive transient voltages which may appear therein. In the construction shown in Fig. 1, a shaft carrying three insulating wheels each provided with three peripheral contacts connected to earth by an earthed contact rubbing on the shaft is driven by a synchronous motor supplied by the system to be protected, so as to rotate at one-third the speed of the motor. The phases of the system are connected each to a hinged contact 12 which bears on one of the wheels. In the form shown in Fig. 3, three insulated arms 20, 21, 22 displaced at 120 degrees with respect to each other and displaced also axially along the shaft, are driven synchronously with the frequency of the system so that the arms periodically bridge the gap between a post 26 to which one of the phases is connected and an earthed post 27, allowing of spark discharge to earth.

Title: Stereoscopic picture projection apparatus
IPC: G03B35/20
Filed: 1948-09-22
Abstract: 650,612. Stereoscopic pictures. LOMAX, F. Sept. 22, 1948, No. 11430/46. Drawings to Specification. [Class 97 (i)] [Also in Group XL (b)] Two pictures of a stereoscopic pair, corresponding to left and right eye viewpoints, are projected in superposition on a screen, with the two outlines of an object, desired to appear in the plane of the screen, registered. The screen has a degree of transparency or reflection, according as transmitting or opaque, between 25 per cent and 85 per cent of that of clear glass or of a plane mirror respectively, this percentage representing the light transmitted or reflected without substantial deviation, the diffusing properties of the screen being only sufficient to enable a single picture to be viewed, as it is said to be able to be, in three dimensions without duplicated outlines from the separate pictures. Materials quoted as suitable for a transmission screen are waxed paper, semi-transparent nylon or plastic cloth of the film or woven kind, slightly exposed and developed photographic film, oiled silk or cloth. Materials quoted for a reflection screen are metal foil, slightly patterned, and spun glass cloth, alternatively a beaded screen may be used. The two pictures of the pair may be separately projected on to the screen. By the addition of another lens the two projected images may be formed in superposition on a photographic medium to produce a single superposed picture for projection in a normal projector on to the special screen. Alternatively, such a picture may be produced by photographing the projected pictures as superposed on the screen. A superposed picture may be produced directly by exposure in a camera having spaced objectives behind which are mirrors reflecting the light beams laterally and inwardly to other mirrors reflecting rearwardly through other lenses on to the film. Alternatively, viewing screens may be arranged behind the two lenses of a stereoscopic camera and images of the images thereon superposed on a film by further lenses.

Title: Improvements in or relating to fluid pressure valves
IPC: B60T13/40
Filed: 1948-04-26
Abstract: 660,795. Fluid pressure brakes. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. April 26, 1948 [May 14, 1947], No. 11443/48. Class 103 (i). In a relay valve for the fluid pressure brake system on a vehicle in which the pressure supply from main and auxiliary reservoirs 4 and 9 to a brake cylinder 10 is regulated by a self-lapping valve assembly 27, 28 controlled by the action of the pressure from a driver's valve 6 acting in chamber 22 on the diaphragm 38 and the valve operating element 30, the element 30 is also subject to the action of the control pressure acting in a further chamber 24 on a diaphragm 41 secured to a member 47 having a lost motion connection with the element 30, by which means it is arranged that the initial force tending to open the valve 27 to supply the brake cylinder is double that which would normally be applied. For any degree of opening of the driver's control valve 6, after a period of time has passed the pressure in chamber 22 is transmitted to chamber 23 through the restricted opening 40 so that the effect of the pressure in chamber 24 acting on diaphragm 41 is neutralized. The lost motion connection 48, 50 between member 47 and element 30 prevents any interference with the normal self-lapping action. During release of the brakes the initial exhaust of air from the brake cylinder is amplified in a corresponding manner. The brake valve 6 may be such as that described in Specification 488,208, [Group XXIX].

Abstract: 954,189. Sampling liquids. A. MURPHY. March 22, 1963 [May 25, 1962], No. 11462/63. Heading B8N. Apparatus for the extraction of a sample of liquid, such as milk or beer, from a container 9 comprises a sample receiving chamber 7 connected by a pipe 10 to the container, a sample collecting bottle 19 removably mounted upon valve means 13 adapted to put the bottle into or out of communication with an opening 15 in the chamber, and means 1, 2 for applying a vacuum or a gaseous pressure alternately to the chamber depending on whether the bottle is brought into or out of communication with the opening. The chamber 7 is connected via a pipe 8 to a solenoid-actuated valve 5 which has two inlets 3, 4 connected to a pressure pump 1 and a vacuum pump 2 respectively. The valve means is in the form of a slide 13 normally held in the position shown by a spring 20 but which can be moved, via the bottle 19 and rubber connection 16 attached to the slide, so as to bring a port 14 in the slide into communication with the opening 15. Upon effecting the latter movement micro switches 17, 18 are operated so as to energize the solenoid valve, a time-delay circuit for the solenoid and the vacuum pump 2. Liquid is then drawn from the container 9 into the chamber 7 where it drains into the sample bottle 19, the amount of liquid being determined by the sitting of the time-delay circuit. Upon release of the slide to the position shown, the bottle is removed and the position of the switches is such as to stop the vacuum pump and start the pressure pump which then forces air through the pipe 8, chamber 7 and pipe 10 thereby clearing them of any residue liquid. All the pipes are preferably of transparent plastic.
