IPC: H01M4/64
Filed: 1951-03-05
Abstract: 689,003. Batteries. CHLORIDE ELECTRICAL STORAGE CO., Ltd. Dec. 17, 1951 [March 5, 1951], No. 5234/51. Class 53. An accumulator grid is made of wire gauze of copper, brass or bronze which is dipped in molten lead or an alloy of lead with tin or antimony. After the lead or alloy has cooled, the warp and weft wires of the gauze become rigidly interlocked. Large pieces of the coated gauze may be cut to size and the exposed metal at the cut edges may be covered with lead by a further dipping process or by means of a hot iron. Alternatively, the cut gauze may be placed in a mould and an outer frame of lead cast round it. The grid may finally be covered with an electrolytically deposited layer of lead, tin or a lead alloy and pasted with lead oxide. The wire used for making the gauze may be coated with lead or alloy before weaving and the gauze heated in an oven till the lead fuses and locks the whole together. The Provisional Specification states that metals other than copper, brass and bronze may be used for the grids which may be made by stamping machining or casting.

Abstract: 1527924 Vehicle tow bar AGRICULTURAL REQUISITES & MECHANIZATIONS Ltd 11 Feb 1976 05322/76 Heading A1P An assembly for raising and lowering a tow-bar comprises a tow-bar 1 pivoted on a tractor, or other vehicle, 4 and coupled, via links 9, to a hydraulic ram 6, also pivoted on the tractor 4, and further comprises means 18-22 for locking the tow-bar I in its raised position. The tractor is reversed until the hook 2 lies under the tow hitch, and then the ram 6 is extended hydraulically, thus pushing up links 9, which slide in cut-outs 15 in a plate 14 bolted to the tractor, and raising the towbar 1 until it rests between projections 17, to limit its transverse movement, with the hook 2 contacting the plate 14. To lock the tow-bar 1 in this raised position, struts 18, pivoted at 7 and biased in a direction X, engage with their notched ends 20 a pivot bar 10 connecting the ram 6 and links 9. To release the tow-bar, it is hydraulically raised a small distance, a handle 22 pulled forwardly against the bias X, and the tow-bar then lowered hydraulically.

Title: Improvements in or relating to grabs
IPC: B66C1/44
Filed: 1947-02-26
Abstract: 634,109. Fluid-pressure servomotor-control systems. ELECTRO-HYDRAULICS, Ltd., SHARP, C. W., and CALDWELL, H. B. Feb. 26, 1947, No. 5627. [Class 135] [Also in Group XXX] A fluid-pressure-operated grab for lifting articles such as bales or barrels comprises a pressure supply system and control means therefor, including a valve operable in dependence upon the difference between the pressure at the grab jaws and a pressure determined by the amount of movement of a member which actuates the system to transmit fluid-pressure to the grab jaws until the said difference reaches a predetermined amount. The grab jaws 8 are mounted on pistons 6, 7 operating in a cylinder 5, fluid for actuating the pistons being supplied from a storage tank 1 by a pump 2 under the control of a valve unit 3 and a piston- and-cylinder device 4. To operate the jaws, a handle 14 is moved in the direction of the arrow 20 to open a valve 12 in the unit 3 whereby fluid flows along the pipe 15, through a port 11 connecting chambers 9, 10 of the unit, and along a pipe 16 to the device 4. At the same time the piston in the device 4 is moved against the action of its spring 22 by the handle 14 so as to open a valve 17 and allow fluid to pass from the pipe 16 through an exhaust port 18 to a pipe 19 leading to the cylinder 5. When the pressure of the fluid entering the device 4 balances the spring 22, the valve 17 is closed by a spring 23 and fluid is maintained in the cylinder at a pressure proportional to the spring load on the handle 14. To release the pressure, a valve 13 in the unit 3 is opened by operating a trigger 24 on the handle 14 to allow fluid to flow back to the tank 1.

Abstract: 1,087,138. Spectrometers. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. Feb. 9, 1966 [Feb.10, 1965], No. 5722/66. Heading G1A. A stellar spectrometer comprises a primary telescope (1) Fig. 1 (not shown), a prism (2) forming a spectrum of the star being investigated along a line, a rotating grating 51 of variable transparency as shown in Fig. 2, on which an image of the line is formed and a photo-electric transducer (7) for converting the light flux modulated by the grating into an electric signal. The grating comprises an annular arrangement of curves defining zones which are alternatively opaque and transparent and are arranged in such a manner that any circle of a radius r within the annulus is divided by the curves into equal parts the angular aperture of which is proportional to r where each element of the linear image is modulated at a frequency inversely proportional to the distance of the element from the centre of the disc carrying the grating. The instrument is intended for mounting on a balloon or for operation outside the atmosphere and the electrical signal is transmitted over a telemetering channel for analysis by an inverse Fourier transformation using a synchronously rotating grating and a source of variable brightness controlled by the received signal. The primary telescope consists of a parabolic mirror (11) having a central aperture and a convex parabolic mirror (12) of the same diameter as the central aperture. The prism is of a material transparent near the infrared region e. g. thallium iodo bromide, and the line is conveyed to the grating by a plane mirror and a secondary telescope similar in construction to the first. The modulated light is concentrated on the transducer by a concave mirror (6).

Abstract: 588,911. Feeding washers.. CHARLES (WEDNESBURY), Ltd., and BEVAN, J. H. March 12, 1945, No. 6057. [Class 78 (i)] [Also in Group XXII] Means for automatically feeding washers one at a time to the tapered end of a reciprocating mandrel and stripping them therefrom after a machining operation, comprises a guideway down which the washers are fed, one behind the other, to a position B, Fig. 4, concentric with the mandrel axis, and spring-pressed abutments J which yield to allow the washer to pass through on the mandrel and then close behind it, stripping the washer from the mandrel on rearward movement of the latter. The feed means is built up from a circular front plate A, with a central aperture a of sufficient diameter to allow a washer to pass, a distance plate C of slightly greater thickness than that of the washers and having in it the feed slot, a backing plate E, and a supporting bracket F. Three slots are provided in the back of the plate A which form guideways for the abutment fingers J the inner ends of which are bevelled thus allowing the forward movement of the mandrel to force the fingers radially outwards against the pressure of springs K, Fig. 1. On the return movement of the mandrel the washer encounters the outer ends of the fingers and the washer is stripped from the mandrel. Meanwhile, the next washer in the slot, which has been resting on the mandrel, falls to the central position at the bottom of the slot as soon as the mandrel moves clear. Screws M threaded into the bent-over outer ends K of the fingers, bear against the circumference of the plate A and act as adjustable stop members to limit the inward movement of the abutment fingers. Guide plates G, Fig. 1, are secured to the plates A and E and these are flared outwardly at their upper ends to form a hopper from which the washers are fed into the slot in the plate C.
