Title: Improvements in or relating to locks
IPC: E05B67/22
Filed: 1942-11-17
Abstract: 563,681. Padlocks. INGRAM, J. F.. Nov. 17, 1942, No. 16228. [Class 44] A padlock of the kind in which the shackle 2 is slidably and pivotally mounted in the case 1, has a spring-urged locking disc 3 rotatably guided in the case by a flange 4. The disc is suitably mutilated so that, inter alia, a portion of the flange engages a notch 5 in the short arm of the shackle, the end of the arm being bevelled so that engagement is automatic when the shackle is pushed home. The disc 3 has ribs 10 between which is slidably guided a spring-shot bolt 11 carried by the disc, the bolt having a flange 12 at one end and an inclined tail rib 16 at the other adapted to engage a corresponding seat 15 in the long arm of the shackle and abut. behind a terminal collar 14. The inclination of rib and seat allows automatic engagement of the bolt under spring action. The long 'arm of the shackle is guided in the rim of the casing and a fixed bridge piece 8 and is surrounded by a torsion and compression spring 13 which ejects the shackle and then rotates it when the lock is released.' The bridge piece carries a spring 6 having one arm 6a bearing against an inturned portion 9 of the disc flange and another arm 6b bearing against flange 12 of the bolt to urge disc and bolt into engagement with the shackle. A key-barrel 17 is rotatably mounted in the casing wall and disc, passing through a slot in the bolt. The aperture 18 in the disc through which the barrel passes has a sector-shaped enlargement to allow lost motion between key and disc so that the key bit first withdraws the bolt and then rocks the disc to release position.

Abstract: 1,081,005. Valves. IMPERIAL CHEMICAL INDUSTRIES Ltd. March 29, 1966 [April 15, 1965], No. 16269/65. Heading F2V. A gas flow programmer comprises a gas passage having a restriction and a valve urged to the open position by a spring and the pressure in the passage downstream of the restriction and loaded to the closed position by the pressure of gas in a control zone which pressure is varied continuously during operation of the programmer. The control is initially charged from the gas supply and during operation the zone is open to exhaust through a valve which causes a linear reduction in the pressure in the zone, thus providing a gradual increase in the flow of gas through the passage.

Title: Improvements in or relating to electric switches with arcextinction by self-generated vapour pressure
IPC: H01H33/02
Filed: 1930-05-27
Abstract: 354,891. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 27, 1930, No. 16362. Convention date, Aug. 29, 1929. [Class 38 (v).] In an "expansion" switch as described in Specification 354,890, the vapour pressure produced bv the arc is used for doing work outside the expansion chamber proper, for example, for replenishing the conducting liquid within the chamber. As shown in the Figure, the vapour pressure in the expansion chamber 10 supported on the insulator 15 is admitted through the pipe 19 and past the valve 20 to a container 16 supported on an insulator 17. The container 16 is filled with switch liquid to the level proper for the expansion chamber and communicates with that chamber through a second pipe 18. When the circuit is broken pressure is developed in the container 16 (through the pipe 19) and, when the pressure in the expansion chamber is relieved by withdrawal of the contact, the valve 20 closes and the liquid 22 is forced through the pipe 18 into the expansion chamber. Excess liquid runs back until the two levels are the same. In a modification, applied to an earthed auxiliary container which communicates with the expansion chamber through an insulating tube, the pressure at break forces liquid from the auxiliary chamber up a tube into a reservoir from which it falls in drops electrically non-continuous into a funnel communicating with the expansion chamber.

Abstract: 1,034,224. Insulators. BRITISH INSULATED CALLENDER'S CABLES Ltd. April 20, 1965 [April 21, 1964], No. 16492/64. Heading H2C. Conductors 9 are supported by insulators each consisting of rods 2 of resin-bonded fibre of high tensile strength and cross-members 3 of insulating material rigidly joined to the rods at intervals along their length, acting both to restrain the rods from buckling and to increase the surface leakage path. Preferably at least three rods 2 are arranged symmetrically around the axes of the insulator and the cross members are in the form of discs. Sleeves 5 at one end of the rods 2 are welded to a baseplate 6 suitable for attachment to a tower, and sleeves 7 at the other end are welded to bracket 8 which receives the conductors 9. Two insulators may be arranged to form the limbs of a V-shaped frame lying in a horizontal plane, as in Fig. 2 (not shown). A tie member 12, consisting of a resin-bonded glass fibre rod 13 carrying discs 14 is attached to bracket 8 by metal sleeve 15 and to the tower by metal sleeve 16. The rods may be straight or curved, parallel or a varying distance apart while retaining the said symmetry. They may be solid, or hollow and filled with e.g. polyurethane foam or a fluid dielectric material. The fibres may be of glass, quartz or lava. The bonding resin may be an epoxy resin with a high resistance to tracking. Alternatively the rods may be coated with butyl or ethylene-propylene rubber or other tracking resistant resin. The cross-members also are preferably of tracking resistant material, e.g. epoxy resin bonded glass fibre, optionally containing alumina, which can be dough-moulded in situ on the rods, or preformed e.g. by vacuum casting and subsequently attached to the rods by an adhesive based on the same resin as the bonding resin. Alternatively they may be of structurally strong material coated with butyl or ethylene-propylene rubber. The preformed discs may have holes through which the rods pass. Adhesion between the in situ moulded discs is aided by interlocking means such as grooves, ribs, projections or recesses preformed on the rods. At least some of the cross-members and supplementary members which may also be attached to the rods, may be shaped, e.g. by having ribs, to increase further the surface leakage path. They may also be shaped to act as insulator steds, e.g. as hollow cones or annuli of triangular or V cross-section.
