Abstract: 830,284. Fluid pressure braking systems. CLAYTON DEWANDRE CO. Ltd. June 30, 1958 [July 10, 1957], No. 21908/57. Class 103 (1)] An hydraulic brake-operating mechanism comprises a pumped constant flow circuit throttled by manually operable control means to create pressure for transmission to the brake actuating cylinders, and an hydraulic accumulator for supplying pressure liquid to the brake actuating cylinders should the required rate of pressure build up be greater than can be provided by the constant flow circuit, or should the circulating pump fail, the control means incor. porating two valve units each controlling independent brake systems or service lines fed by independent accumulators, the units being interconnected so that pressure generated in the first system operates the valve unit in the second system, and being arranged such that should pressure failure occur in the first unit then the second unit can be operated mechani. cally through the first unit by the brake pedal. A valve seat 22 is moved against the coned.end of a stem 11 by a foot pedal operated plunger 3 to interrupt the constant fluid flow through passage 7, bore 2, bore and ports 4 in plunger 3, and passage 9 to build up pressure in a brake service line, this pressure reacting on plunger 3 to provide " feel " at the brake pedal. Increased displacement of plunger 3 moves stem 11 in a fixed sleeve 10 to raise valve head 12 from its seat 15 to connect an accumulator via port 21, 20, space 18, enlarged bore 2a and passage 24 to the brake line. Pressure in bore 2a acts on a piston 30 of valve V 2  to move, through body 29 and abutment 34, valve elements 11a, 12a against spring 16a to connect an accumulator via port 37, 38, valve elements 11a, 12a, ports 35, 36 to a related brake line. On brake release the valve elements are closed on to their seats by springs 16, 16a and plunger 3 and piston 30 return to the shown position 5, fluid from the second brake line exhausting past a one-way ball valve 33 and piston 30 which is raised from body 29, to valve unit V 1 , the return of the piston assembly 29, 30 being limited by a ring 40 abutting an insert 14 in bore 2a. On failure of pressure in unit V 1  continued movement of the foot pedal is transmitted via plunger 3, valve elements 11, 12 and extension 12x to the piston assembly of unit V 2 . The units V 1 , V 2  are formed separately and are connected together, but in one embodiment in the Provisional Specification they are formed in a common housing.

Class 20(2) [Also in Group XXV] In roof bars for mines engaging end to end by tongue and fork and connected by a swivel pin and a wedge 20, Fig. 10, the wedge has two curved surfaces Fig. 8 and the apertures 12, 13, Fig. 21, in the tongue, either of which is adapted to accommodate the wedge, have the same inclination and curvature so that the whole of that part of one of the curved surfaces of the wedge lying within the lug aperture engages the surface of the aperture. To install the bar 11, it is pivoted by the aperture 12 about the wedge 20, engaged in the aperture 16 of the fork of a bar 10 already in position, until the swivel pin can be inserted in holes 14, 18. The angle between the bars can be varied by inserting the wedge in holes 12, 16 or 13, 17 to a greater or less extent or by inverting one bar relatively to the other. The wedge may have a key 23 adapted to engage a key-way in either of the apertures, 16, 17 in the fork. The hinged pin has two curved surfaces with centres at 28, 29, Fig. 5, and is held captive by a locking plate engaging a flat 25 and may be tapered. The roof bar comprises two rolled steel joists welded together at the flanges.

Abstract: 1,091,410. Coin freed vending machines. STOCONTROL SERVICE Ltd. May 18, 1966, No. 22197/66. Heading G4V. A coin is guided down a channel at the rear of the machine into a slot 5 in a sliding drawer 3 which supports a stack of articles. Movement of the drawer moves the coin to pivot a spring-biased pawl 23 out of engagement with a rack 22 on the underside of the drawer whereby an article can be retrieved from the recess 6 in the drawer, the rest of the stack being supported on the raised rear part 10 of the drawer. To prevent jamming of the mechanism if a second coin is inadvertently fed to the machine before the first coin has been cleared, the second coin initially rests on the edge of the first coin and is held by the coin guide so that as the drawer is opened the second coin drops on to a surface 39 which guides it on to prongs 40 which are spring biased so that they move under the coin guide as the drawer is withdrawn. Closure of the drawer retracts the prongs by engaging a projection 45 and allows the second coin to drop into the slot 5.

Abstract: 1,098,616. Capacitors. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 26, 1965 [May 27, 1964], No. 22347/65. Heading H1M. A body of dielectric material for a capacitor is manufactured by firing a finely divided mixture of two dielectric materials having different dielectric constant/temperature characteristics and a glassy binder present in such proportion that it forms at least 15% by volume of the eventual body. The binder keeps the granules of the two materials separate and prevents their interaction during fabrication so that the dielectric constant of the formed body is related to the aggregate of the dielectric constants of the individual materials and may be substantially independent of temperature over a selected range. The dielectric materials may be ferroelectric, e.g. compounds having the perovskite structure and each of the two materials, which have different Curie temperatures, may be a mixture of barium titanate and strontium titanate, or lead titanate or lead zirconate. The glass binder may be barium borosilicate, lead borosilicate or bismuth trioxide. A body having a dielectric constant substantially independent of temperature at 45‹ C. and above is formed by mixing equal quantities of two dielectric materials, the first comprising a sintered mixture of 85% barium titanate and 15% strontium titanate, the second a sintered mixture of 75% barium titanate and 25% strontium titanate, and the glass binder and firing. In the capacitor shown, a first electrode 12 of e.g. platinum, gold or silver, is deposited on ceramic base 11, and the above described mixture, dispersed in a squeegee medium applied by screening to form dielectric layer 13.

Abstract: 402,197. Cutting extruded clay into bricks. MAJOR, G. H., c/o Gipsy Lane Brick Co., Fairfax Road, Leicester. Aug. 10, 1932, No. 22395. [Class 87 (ii).] In the transverse cutting of an extruded stream of clay into separate wire-cut bricks, the stationary stream is held rigidly during the cutting- operation and the wires are moved bodily downwards through the clay in addition to moving to-and-fro longitudinally to give a sawing cut. The clay stream is delivered to a table 2 and is pressed against the rigid back plate 4 by the raising and inward movement of a front plate 8 actuated from the rocking shaft 20 by means of the treadle 19. This plate is partly counterweighted at 25 so that it will drop slowly by gravity when the treadle is released. A frame 37, furnished with tensioned cutting-wires spaced by a slotted gauge 50, is pulled down by the handle 52 about its pivot 33 so that the wires pass through slots in the members 4, 2 and 8 and completely sever the bar. The shaft 33, on which the frame is mounted loosely is driven continuously so that eccentric pins 35 on its ends engage members 39 on the cutting-frame and reciprocate it continually in a longitudinal direction. The frame is partly balanced by a slidable counterweight 59 which changes its radius of action so that the frame will either remain permanently raised or lowered. The cut bricks are pushed on to a table supported on the ends of the arms 61 and are removed with the table.

A tyre building drum consisting of circular end members 1 and 3 joined by a collapsible but axially inextensible tubular bladder 4 has spherically curved flanges 5 on the end members. These flanges serve during use of the drum, as a support for the tyre beads and, when the drum is collapsed, to allow its periphery to lie on an imaginary sphere 5a (Fig. 2) to facilitate removal of the tyre band 10. The bladder, whose axial extensibility is ensured by metal or fabric reinforcing elements 4a embedded in its rubber or like body, is secured to the end members by clamping between them and said flanges 5. These flanges have air holes 8 to facilitate removal of the tyre band, the interior of the bladder has ribs or grooves 11 to facilitate its collapse and the interior of the bladder may be pressurized or exhausted by way of a bore 7 in its supporting shaft 2 which opens into the drum at 7a. The drum collapses and expands by movement of end member 3 along shaft 2, which movement may be effected solely by pressure or vacuum applied to bore 7.
