Title: Improvements relating to hydrodynamic brakes
Inventor: WESTWELL WILLIAM GRIFFITHS
IPC: F16D57/04
Filed: 1965-05-26
Abstract: 1,138,622. Hydrodynamic brakes. PERKINS ENGINES Ltd. 27 April, 1966 [26 May, 1965], No. 22283/65. Heading F2E. A hydrodynamic brake comprising a twopart easing 12A and 12B forming a stator having pockets or vanes 11A and housing a rotor 10 having coacting pockets or vanes 11B, incorporates a plurality of shutter members 16 pivoted at one end on the easing between the stator and rotor to form an adjustable iris, said shutters being moved to the open position, Fig. 2B (not shown), when hydraulic fluid is admitted to the casing to actuate the brake and being moved to the closed position, Fig. 2A (not shown), to reduce windage losses when the casing is empty of hydraulic fluid. As shown, the shutters are formed by arcuate metal plates, each having a pin 17 engaging in an associated slot 19 of a rotatable cam ring 18 to define an " iris "-type shutter. The cam ring is rotated by a rack 21 engaging a ring gear segment 20, said rack being moved to the left by hydraulic, pneumatic or mechanical control means (not shown) connected thereto by a control rod 21C to open the shutters. A control rod extension 21B is coupled to a control valve 22 so that said rack movement permits entry of fluid into the casing. Movement of the rack to the right to effect closure of both the shutters and the control valve supply is effected by a spring 21A. The shutters can only be moved to their closed position when there is no hydraulic fluid in the flow path and hydraulic fluid cannot be admitted to the casing when the shutters are closed; said pins extending through co-operating slots (52) in the free ends of said shutters. The shutters are urged towards a closed position during brake release by a spring (57) acting between the other arms of the bell-crank levers but are maintained in the open position shown during brake application by a pair of hydraulic rams connected to a control valve (58) which also controls the admission of fluid to the machine through a supply valve (22A).

Title: Improvements in or relating to a pressure relief valve gauge for pressure cookers
IPC: A47J27/09
Filed: 1948-08-24
Abstract: 671,361. Pressure relief valves. NATIONAL PRESSURE COOKER CO. Aug. 24, 1948 [Sept. 27, 1947], No. 22327/48. Class 135. A relief valve for pressure cookers comprises a hollow body member 23 loosely supported on the end of a normally vertical vent pipe 11 by means of a valve member 19 carried inside the body member at its upper end and detent means such as the washer 25 extending inwardly from the body member opposite a portion 13 of the vent pipe of reduced diameter and arranged to permit the body member and the valve member to rock in a pendulous fashion on the vent pipe to relieve excess pressure in the cooker, the centre of gravity of the body member and the valve member being below their point of pivotal' support on the vent pipe. The vent pipe 11 also has an enlarged .head portion 14 and a threaded part 12 adapted to be screwed into the lid of the cooker. The washer 25 is secured in the base of the body member 23 and has inwardly directed projections 26, Fig. 3, the inner surfaces of which are only slightly spaced from the head portion 14 so that unless the body member 23 rises axially, as when it is deliberately removed from the vent pipe, it will be prevented from leaving the vent pipe, even when the cooker lid is turned almost upside down, due to the engagement of the projections 26 with a shoulder 15. One or more ring weights 31 are slidably mounted on the body member 23 and supported by a snap ring in a groove 33. The weights 31 are prevented from sliding off the cap member by a flange 34 on a cap member 35 removably secured on a threaded extension 36 of the valve member 19. Fig. 7 shows a modification in which the retaining washer 46 is of rubber and its projections 47, Fig. 8, are adapted to engage the head portion 14 frictionally so that some effort is required to remove the body member 44 and the valve 41 from the vent pipe. This washer 46 is itself retained by a metal ring 48. The ring weights 52 are kept on the body member 44 by a snap ring 55 which can be depressed into a groove 56. The body member 44 is surmounted by a knob 49 of insulating material. In Fig. 11, the body member 61 has a conical flange 63 to support correspondingly shaped weights 73. These are kept in place by the overhanging edge of a detachable knob 72 of plastic material secured to the valve member 67. Secured in the body member 61 is a retainer sleeve 65 with projections to co-operate with the shoulder 15. In a further modification, the knob 72 is replaced by a wire clip which overhangs the weights 73 and has a circular gripping portion engaging a groove in the valve member 67. Specification 645,945, [Group XVIII], is referred to,.

Abstract: 706,137. Projectiles for industrial operations. HILTI,M., [trading as MASCHINENBAU HILTI OHG.], and RAMECO SOC. ANON. Oct. 2, 1951 [March 19, 1951], No. 22930/51. Class 9(1) A bolt or the like adapted to be anchored into a base by the propelling gas thrust of a firing device, has its rear end portion of a section greater than that of the barrel of the firing device, and is composed, at least in the region of this end portion, of a tough non-fouling material which is softer than that of the bolt itself. By this means the end portion is converted by the gas thrust into a seal which bears cup-like in the barrel. In one construction, Fig. 1, the bolt comprises a main body 1, a guiding.element 2, and a rim 3. On firing the rim strips off at the sharp edge of the sealing in the cartridge chamber, and the small annular part of the rim remaining bulges out, owing to the softness and toughness of the material and seals the bore of the barrel. In modifications the bolt is formed integral with a guiding disc, and a flanged cap of a tough and soft material is secured to it as by welding, brazing or screwing. In another modification, Fig. 14, the cap 19 with a strip-off rim 21 is connected by a screw 20 to the screw threaded part 18 of the projectile. In further modifications the bolt is screw-threaded as at 33, Fig. 19, to receive a threaded sleeve 38 whose surface 39 guides the bolt through the barrel. The sleeve limits the penetration of the bolt into the material into which it is fired. In Fig. 19 the sleeve is separate from the strip-off plate 40, but in a modification these two parts are connected together.

[Class 2 (iii)] Isobutane is produced by contacting nbutane or n-butane-containing mixtures substantially free from olefines, in the liquid phase at normal or raised temperatures not exceeding 110‹C., with an aluminium chloride catalyst in the presence of hydrogen halide, preferably hydrogen chloride. The latter may be present in small amount but preferably has a partial pressure of at least about 3 atmospheres. At above about 70 ‹C. with a HC1 partial pressure of 4 atmospheres, more than 50 per cent. of the butane can be isomerized in a few hours. The process may be continuous, and the isobutane removed by raising the temperature and/or reducing the pressure. In examples, a mixture of n- and iso-butanes is treated with about half its weight of aluminium chloride in a rotating autoclave. HC1 is introduced until its partial pressure varies from 3-20 atmospheres at 20‹C. Reaction temperatures up to 100‹C. with contact times of 4-64 hours are used. At 120‹C. little isomerism but extensive decomposition occurs. Specification 498,512 is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of an aluminium bromide catalyst, optionally in the presence of hydrogen halide, this being the subjectmatter of Specification 512,408. It also includes the use of aluminium chloride or bromide in the form of double compounds with aromatic hydrocarbons, e.g. butyl-or tripropyl-benzene. Additional examples describe the treatment of butane mixtures by shaking with aluminium bromide in a closed vessel at 30, 50 and 80‹C., hydrogen chloride optionally being present in the last case. This subject-matter does not appear in the Specification as accepted.
