Abstract: 902,849. Clocks. SMITH & SONS (ENGLAND) Ltd., S., and BRACKENSEY, A. H. Dec. 23, 1959 [Dec. 31, 1958; July 10, 1959], Nos. 42226/58 and 42226/58. Class 139. In a clock having a mainspring which is repeatedly rewound by an electromagnet, the switch contacts of the electromagnet circuit are located in a hermetically sealed container and are actuated magnetically. The mainspring 65 is attached to the armature 59 pivotably located between the poles 45, 46 of the electromagnet 42, 43, 44. The switch of the electromagnet circuit is located within a hermetically-sealed container 51 and comprises a stationary contact 48 and a contact 49 on a pivoted bar magnet 53 urged clockwise by a spring 73. A permanent magnet 57 outside the container 51 urges the bar magnet 53 in the direction to open the switch 48, 49. As the mainspring 65 unwinds to drive the going train, the armature 59 is rocked counterclockwise and a permanent magnet 64 approaches the magnet 53 which is suddenly moved to close the switch 48, 49, whereupon the electromagnet 42, 43, 44 is energized to rock the armature 59 clockwise and restress the mainspring 65. The invention may be applied to the clock described in Specification 550,982.

Title: Improved defrost system and parts therefor or the like
IPC: F25D21/02
Filed: 1966-09-29
Abstract: 1,113,565. Thermal and fluid actuated switches. ROBERTSHAW CONTROLS CO. 29 Sept., 1966 [23 Oct., 1965], No. 43646/65. Heading H1N. [Also in Divisions F4 and G3] An electric switch used to energize and deenergize an electric heater for defrosting a refrigerant evaporator (see Division F4) is actuated in one sense by a change in pressure and in the opposite sense by a change in temperature. The switch comprises a contact 46 movable between fixed contacts 50, 51 by a snap-acting spring 47 having an operating plunger 49. The latter is acted on by a lever 62 which is pivoted at 63 and is in engagement with a plunger 60 attached to a diaphragm 58 in a chamber 59. When the pressure on one side 57 of the diaphragm rises plunger 60 pivots lever 62 clockwise against the action of a spring 65, thus permitting spring 48 to move contact 46 to contact 51 and energize the defrost heater. The heater is de-energized when the evaporator temperature rises sufficiently to cause a temperature-responsive element 66 to expand and pivot a further lever 70 which abuts and pivots lever 62 in an anti-clockwise direction. The rise in pressure in chamber 59 occurs when the flow of fluid through a nozzle directed towards the evaporator surface is obstructed by frost accumulations.

Title: Locking device
IPC: F16B1/00
Filed: 1969-09-04
Abstract: 1,236,530. Locking rotary elements in any position; positive detents; fluid-pressure control. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. 4 Sept., 1969 [11 Sept., 1968], No. 43812/69. Headings F2E and F2F. A device for locking in any position a rotatable or displaceable member having an irregular surface extending in the direction of movement of the member comprises an abutment means movable to and from the surface (transversely to the rotatable member's direction of movement), the abutment means being deformable in a direction parallel to its direction of movement to conform to the surface profile on engagement therewith, whilst being rigid in the direction of movement of the rotatable member. As shown, rectangular lamellae 59 are located in mutual contact in a through-opening 54 of rectangular cross-section in a sleeve 43 mounted in the annular skirt 37 of a piston 16. Each lamella has a longitudinally extending slot, and in the disengaged position of the device (not shown) the slots are mutually aligned and aligned with two corresponding slots 48, 49, in the wall of the sleeve 43. A pin 53, bridging the skirt 37, extends through all the slots. Between the inner end of the stack 71 of lamellµ 59 and the end 32 of piston 16 is located a rubber disc 39 which in the disengaged position of the device is parallel-sided (not as shown). The body (e.g. a model support in an aerodynamic wind tunnel) which is required to be locked in position is integral with a sector 11 having teeth 12, which may be the means used for orientating the body. In operation, compressed air is supplied to space 67 through port 68, forcing the lamellµ into contact with the teeth 12, or partly into the gaps between the teeth (see Fig. 8). The corresponding irregular shape of the inner end of the stack is accommodated by the rubber disc 39, Fig. 2. The irregular array of slots in the lamellµ is seen enclosing the pin 53, Fig. 2. The mutual support provided by the contact (over almost the whole face areas) of adjacent lamellµ, and the complete filling of the opening in sleeve 43 by lamellµ, together ensure that the stack is rigid in the direction of movement of sector 11, even if vibrations occur. Also the lamellµ, being relatively thin, can accommodate any position of the teeth 12. The piston skirt is prevented from rotating by a key 9, Fig. 3. When the pressure at port 68 is relieved, resilient washers 29 move the piston to the right again until ring 33 meets internal face 35. The compressed air may be dispensed with, in which case the washers 29 are located so as to apply the piston, and the piston is withdrawn by connecting port 68 to vacuum. The rubber disc 39 may be replaced by a sealed bladder filled with oil or grease, or by a plurality of springs cut out of the lamellµ or attached to them. In a modification (Fig. 9, not shown) the teeth 12 on sector 11 are replaced by rectilinear grooves or splines perpendicular to the plane of the sector.

Abstract: 1,068,332. Filtering liquids; purifying solids by filtration. GLAXO LABORATORIES Ltd. Nov. 6, 1963 [Nov. 20, 1962], No. 43876/62. Heading B1D. A suspension of clay-like or jelly-like material (e.g. hydrated alumina) is forced by a pump 8 from a reservoir 2 up a filter tube 10 at a rapid rate such that a thin layer of particles is formed and maintained on the surface and acts as a filter medium. Filtrate is collected in a vessel 11. Where the intention is to purify the solid, fresh liquid is introduced at 6 through a constant-level device 7, until the desired degree of purity has been reached, whereupon the supply at 6 is cut off and the circulation is continued, to concentrate the suspension. The tube 10 may be of synthetic fabric optionally supported externally with wire mesh, or of gauze or of porous plastics, metals or ceramics. Rapid flow rate may be achieved by flattening the filter tube or locating a rod within it or, for inward flow, enclosing it in an imperforate tube. The method may be adapted to the purification of fermentation liquors, e.g. to remove mycelium.

The projections 16 are conically recessed to receive the conical projections 13 and the two are interlocked by a spring loaded shear pin extending through an aperture in both projections. When assembled the deck and base are parallel and spaced by the projections to form lifting fork receiving channels. Openings 14 having tapering peripheries 14a are provided in the deck 10 to receive inserts of various configurations selected according to the load to be carried. Sockets 30 at the comers of the deck shown receive posts for supporting load retaining mesh &c. and the mesh side walls formed may be pivoted at mid-post height to permit access to the load when a plurality of such pallets are stacked. Sockets in the underside of the pallet base members receive the tops of the posts to facilitate said stacking. Sockets may be provided at various locations over the pallets to permit specialized formations of parts. The lower ends of the projections 16 on the deck are capable of directly supporting the deck on the ground in the absence of a base member. The components of the pallet system are formed from moulded plastics material.
