Filed: 1975-04-15
Abstract: 1488178 Pyrotechnic gas generator SOC NATIONALE DES POUDRES ET EXPLOSIFS 15 April 1975 [29 April 1974] 15455/75 Heading F1L A pyrotechnic gas generator suitable for rapidly inflating an automobile safety cushion comprises a cup shaped casing 2, Fig. 1, the open end of which is held against a base 1a by resilient means such as a Belleville washer 6 bearing against a cover 1b threaded to the base, casing 2 containing a pyrotechnic charge fired by an igniter 9 producing gas the pressure of which moves casing 2 away from base 1a thereby forming a flow orifice of variable area through which the gas passes into a cooling chamber containing solid coolant 13, 14 and subsequently out of the generator via filters 17a, 17b and apertures 18. Filter 17a is composed of a grid, and filter 17b may comprise woven metal fabric or granules of corundum or alumina separated by a gauze 16 from the coolant 14 which may consist of sodium bicarbonate pellets and which is separated by a grid 15 from coolant 13 comprising for example potassium perchlorate pellets containing a decomposition catalyst, e.g. copper chromite. The pyrotechnic charge comprises cellulose triacetate, potassium perchlorate, tricresyl phosphate and acetylene black and is supported by a grid 8, and the igniter contains zirconium and cupric oxide. Casing 2 lies within a cylindrical guide 3 having a flared lower portion 4. The Belleville washer acts as a pressure regulator and also as a pressure limiter by becoming flattened when the  gas-pressure has reached a predetermined value causing a large increase in the flow orifice area which rapidly reduces the pressure. The Belleville washer may be replaced by an elastic toroid gasket, Fig. 2 (not shown). A supplementary pressure limiter e.g. a shear ring may also be utilized. A shear ring may also be used as the pressure regulator, Fig. 4 (not shown) and injection apertures (21) may be disposed near the open end of casing 2. In another embodiment, Fig. 3 (not shown), the base of the inner casing bears directly against the cover 1b and is made of material such as thin sheet metal which can distort to act as the pressure regulator. A supplementary pressure limiter may also be included and it may comprise a shaft with a shearing shoulder resting on a boss on the interior of cover 1b and having a bore for guiding the shaft. In another embodiment, Fig. 5, the inner casing 32 and base 22 are axially aligned and maintained in contact by an elastic washer 33 which deforms during combustion of the charge to act as a pressure regulator and fractures when a predetermined pressure is exceeded to act as a pressure limiter, the gas passing to cooling chamber 26 and filter 30 via ports 24b.

Abstract: 1,170,283. Hydraulic brakes; valves. GIRLING Ltd. 23 March, 1967 [7 April, 1966], No. 15581/66. Headings F2F and F2V. A pressure reducing or intensifying valve for use in hydraulic vehicle braking systems consists of a housing 10 having large and small diameter bores which are substantially coaxial and contain separate corresponding large and small diameter pistons 16, 17 one of which carries a pin 21 for holding a ball or similar valve element 19 off a seat member 18 under the influence of a spring 24 which acts directly on the other piston and through an external yoke 23 on the said one piston, assuming the housing 10 is fixed, or alternatively through the housing 10 if, as described with reference to Fig. 3 (not shown), the latter is free to move and the yoke 23 instead is fixed. In either case. increase of hydraulic pressure at the inlet 12 causes relative movement between the pistons and the housing whereby pin 21 is withdrawn and the valve element 19 seats under the influence of a light spring 22 when output pressure at the outlet 11 is in a predetermined ratio to that at the inlet 12. As shown, the valve gives a proportional reduction in pressure, but by changing over the outlet and inlet and mounting the pin 21 on the piston 17 to control a valve element in the chamber 13 a proportional pressure increase would be effected instead. In a modified arrangement which is functionally identical (Fig. 4, not shown), assembly is facilitated by forming the cylindrical chamber 14 in a removable sleeve which holds in the seat member 18 and is secured in place by a threaded bush.

Filed: 1943-09-24
Abstract: 568,344. Photographic focusing devices. KODAK, Ltd. Sept. 24, 1943, No. 15726. Convention date, Sept. 26, 1942. [Classes 97 (i) and 98 (i)] An optical focusing device comprises a simple or compound bi-focal lens and light-filtering means associated therewith to form two sharp differently coloured images displaced one from the other along the optical axis, and an imagereceiving surface so disposed that the two images appear thereon of differing magnification when the device is not in focus on a given object, the distance between the bi-focal lens and image-receiving surface being adjustable so that when the colour fringe due to the overlapping images of differing magnification disappears, i.e. when the two images viewed on the image-receiving surface are merged into a single image, the device is correctly focused for the given object. As shown in Fig. 1, a compound objective comprises a number of lenses 10 and a front lens 12 divided into the differently coloured zones 13 and 14, the zones 13 focusing on a plane 15 and the zones 14 on a plane 16. At the intermediate plane 11 the images from the bi-focal lens are of the same magnification and the colour fringes disappear. The bi-focal lens may form the finder lens of a twin-lens camera. A ground glass may be placed in the plane 11 and an eyepiece provided to magnify the image. As shown in Fig. 4, the bifocal lens 25 is carried by the lens board 26 of the camera C having an objective L of which the front lens cell 35 is adjustable for focusing. A tube 32 carrying a ground glass 31 is slidable in a tubular support 29 fixed in a bracket 30 on the camera body. The image on the ground glass is viewed through an eyepiece carried by the rear end of tube 32, and a pointer 40 on the tube 32 co-operates with a scale 33 on the support 29 to give the setting for lens cell 35. In a modification the front of the camera may be moved for focusing and the disappearance of the colour fringes determines focussing of the camera objective. In modifications, the bi-focal lens may take the forms shown in Figs. 8 and 10. Colouring matter is applied to the lens zones in any desired manner. The bi-focal lens may be of glass or moulded from plastic.

Filed: 1919-06-28
Abstract: 151,726. Forbes, A. J. June 28, 1919. Letter-spacing mechanism.-A differential escapement-mechanism is adjustable, for (1) single-spacing on operating the character-keys and double-spacing on operating the spacing-key, the spacing-key and a character-key being operated simultaneously at the end of a word, (2) singlespacing on operating either the character-keys or the spacing-key, or (3) double-spacing on operating either the character-keys or the spacing-key. The play of the loose dog 2 is limited for single-spacing by a stop 6 consisting of a lever 7 mounted on a pivot 8 and connected by a link 12 to the, spacing- key lever 13. the link being formed with a hook 14 for engaging the end 11 of the stop-lever. The link passes through a guide-slot 17 and can be shifted to the right or left of the mid-position by means of a forked lever 16, Fig. 2. When the link is in mid-position, the stop-lever is rocked upon operation of the spacing-key, and the loose dog can move into contact with a stop 4 to permit of double-spacing. When the link is shifted to the right, the hook is disengaged and single-spacing is effected by the character-keys or spacing- key. When the hook is moved to the left, a bevelled part engages the end 11 and rocks the stop-lever, thereby permitting the loose dog to move into contact with the stop 4 to effect doublespacing on operating the character-keys or the spacing-key.
