IPC: C03B19/00
Filed: 1929-03-04
Abstract: 330,268. Haddan, R., (Corning Glass Works). March 4, 1929. Condensers. - Sheets of glass of thickness less than 0.015 inch, having a softening point preferably below 700‹ C. and having a low coefficient of expansion, are used as an insulator, particularly as the dielectric for condensers. Glass containing about 45 per cent lead oxide and having a melting temperature of about 650‹ C. is suitable. In the preferred method of production a predetermined quantity of molten glass is blown into a polygonal mould 10 to form a flat-sided blank 11, which, when blown, is placed on a table 13 and its ends are cut away. The blank is then cut along the edges of adjoining faces which are subsequently separated and cut into sheets 16, Fig. 5, for making condensers. These sheets are interleaved with copper or other conducting sheets 17, and the condenser is heated to fuse the edges of the glass and obtain coalescence between the glass and metal sheets. The fused glass forms an envelope which renders unnecessary the use of an external casing.

Title: Improvements in or relating to burners for vulcanisers
IPC: F23D3/40
Filed: 1919-10-20
Abstract: 157,479. Frost, W., and Frost & Co., Ltd., H. Oct. 20, 1919. Thermally-actuated valves. -Relates to means for reducing or extinguishing the burner flame of a vulcanizer when a pre-arranged tempera.- ture or pressure is reached in the steam chamber. The vulcanizer shown comprises a burner chamber 12 and a water and steam chamber 11 through which flue pipes 17 pass. A valve controlling member or shutter 30 is slidable on pins 32 on the chamber 11 and is supported in position by the friction, caused by the pressure of a bimetallic bowspring 33 mounted adjustably on the pins 32. When the requisite vulcanizing temperature is reached in the chamber 11, the shutter falls, owing to the spring straightening, and the ends 35, 36 of the shutter member close the burner chamber air inlets 10 and the flue pipe outlets so as to reduce or extinguish the flame. In a modification, a shutter plate fits against the side wall of the chamber 11 and the metallic spring is arranged in a recess in the wall so as to press the plate outwards against the heads of supporting- screws. Instead of the bimetallic spring, a flexible diaphragm may normally exert pressure on the controlling-member to produce the required friction. When the vulcanizer is heated to the required temperature, the pressure of the steam on the diaphragm reduces the pressure producing the friction and releases the controlling-member.

Title: Improvements relating to engine starters
IPC: F02N15/02
Filed: 1937-03-11
Abstract: 485,951. Turning-gear. BRYCE, Ltd., and AYRES, J. March 11, 1937, No. 7176. [Class 7 (v)] [Also m Group XXIX] In an electric starter having a fluid coupling between the shafts 1, 18 of the starting motor 4 and the starter pinion 22, a mechanical clutch between these shafts is automatically rendered operative only after the starter pinion has meshed with the engine flywheel and full power is required from the starting motor. As shown in Fig. 1, the pinion 22 is threaded on a sleeve 21 on the shaft 18, which is driven through a fluid coupling comprising members 6, 7, each formed with fluid galleries 8. The member 6 is fixed to the casing 5 of the coupling by a locking ring 9, and the member 7 is bolted to a flywheel member 13 locked on a nut 14 engaging a thread 17 on the shaft 18. When the pinion 22 is fully meshed with an engine flywheel, the load arrests the shaft 18 and continued rotation of the coupling member 7 causes axial movement of the nut 14 on the thread 17, bringing a dogclutch member 20 splined thereon into engagement with a clutch member 11 on the casing 5. The shaft 18 is then positively driven through the clutch 20, 11. A spring 29 yields if the teeth of the clutch abut. In case of backfire of the engine, axial movement of the flywheel 13 is limited by stops 32 thereon and the shaft 18 moves to the left against spring plates 26 interposed between members 27, 28, so that a member 31 on the shaft 18 disengages the clutch 20, 11. In a modification, Fig. 2, the members 26 .. 28 are replaced by a loose ring 36 carrying radial spring-pressed pins 37 chamfered to engage between a cam ring 40 fixed on the coupling member 6 and a pressure ring 41 fixed on the shaft 18, springs 42 being interposed between the rings 36, 41. The pins 37 are displaced inwards upon axial movement of the shaft 18 due to backire. In further modifications, the dog clutch 11, 20 is replaced by a friction cone or plate clutch between the members 13, 5.

Abstract: 799,663. Remote indicating systems utilizing photo-cells. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS, Ltd., and WHITLOCK, R. H. June 13, 1955 [March 12, 1954], No. 7253/54. Class 40 (3). In a remote indicating system comprising a plurality of light-sensitive devices arranged to be irradiated through one or more openings is a mask mounted on a member receiving a movement depending upon the magnitude of a quantity being measured, the devices and openings are so arranged as to divide the whole range of movement of the member into a finite number of divisions in each of which a different device or group of devices is masked or exposed to light, each device transmitting a signal when the member occupies a division to which it refers. The system shown comprises an apertured disc 1 on a shaft 2 the angular position of which is a function of weight. The apertures are in two groups 4, 8 corresponding to decigrams and grams respectively the decigram group being subdivided into a series for each aperture 8. In any position of the disc one of the 10 photo-cells 5 is illuminated via an aperture 4 and one of the photo-cells 7 via an aperture 8 by source 6 disposed on the opposite side of the disc. Signals are fed along individual channels to amplifier 9 the outputs of which operate a remote indicator, printer, &c. The system may be adapted to transmit these signals only when the disc is stationary by means of a further apertured disc on shaft 2 co-operating with a light source and cell to give a fluctuating current which is amplified to give an output proportional to the first derivative of the current which controls means to block the signals when the disc is in motion. The shaft may also bear a toothed wheel or magnetic disc co-operating with a detent or electromagnet whereby the disc may set only in a series of discrete positions so as to prevent simultaneous energization of adjacent photocells. The disc may be replaced by a drum with the apertures spaced axially instead of radially. In a further modification the photo-cells 5 and 7 could be spaced along arcs at angular intervals corresponding to the spacing of the apertures 8, 4 respectively and the series of apertures 8, 4 each replaced by a single aperture.
