Filed: 1973-10-10
Abstract: 1404721 Pressure cooker A E COTTON 10 Oct 1973 47229/73 Heading B1X [Also in Division F2] Cooking apparatus for pressure-cooking food comprises a vessel 1 to contain liquid 3 to be pressurised Having a top opening and a lid 8 having a sealing gasket 13, the lid being fixable to close the top opening of the vessel to maintain a preset pressure therein by means of a pressure valve 10 fixable in a vent 9 in the lid, the lid having attached thereto a perforated plate 16 substantially conforming to the shape and size of the top opening of the vessel, the plate being spaced from the inner surface of the lid. In use the perforations break up the flow of vapour through the vent 9, producing turbulence. The vessel may contain an inner food-containing compartment 2 which may in turn contain a wire basket. Heaters 4 may be provided in that part of the vessel containing the liquid. The lid may be held closed by a screw arm 20 held captive therein but rotatable relative thereto, engaged in a threaded hole in a beam 21.

Title: A Warp Knitting or Similar Machine having an Arrangement for Controlling Two-part Knitting Needles
IPC: D04B23/00
Filed: 1968-10-08
Abstract: 1,192,129. Knitting machines. VYZKUMNY USTAV PLETARSKY. 8 Oct., 1968 [10 Oct., 1967], No. 47560/68. Heading D1C. The sliding tongues 3 of the needles 1 of a warp machine are selectively coupled to the continuously reciprocating operating bar 13 whereby the needles are rendered operative or inoperative or capable of producing tuck stitches. The hook portions 2 of the needles are secured to the continuously reciprocating needle operating bar 6 which in conjunction with the bar 13 determines the knitting operations of the needles. The bar 13 houses a series of pins 17 which are selectively projected under the control of electro magnets to engage or miss extensions 9 of the sliding tongues 3. Consequently depending upon the operation of the electromagnets as controlled by a programme control the pins 17 are either projected or unaffected to determine operation of the needles. The pins 17 may be projected by the action of the electromagnets or withdrawn being normally projected by springs. A bar 27 coupled to the bar 6 or to the bar 13 engages the top of the extensions 9 to return the sliding tongues to their initial positions. Alternatively the pins 17 may be replaced by wires which are actuated by electromagnets. The pins may be actuated directly by the armatures of the electromagnets or by an intermediate slide. In the latter case a grid returns the pins to their initial unselected position after the needles have knitted.

Title: Time Indicator
Inventor: JACKSON DAVID
IPC: G04F1/00
Filed: 1965-11-09
Abstract: 1,169,887. Indicator strips. EXPRESS DAIRY CO. (LONDON) Ltd. 8 Nov., 1966 [9 Nov., 1965], No. 47573/65. Heading B1X. [Also in Division G3] A time indicator (see Division G3) comprises a piece 4 of absorbent material impregnated with a chemical compound which changes colour on exposure to oxygen. The absorbent material is encapsulated in plastics films 6, heat sealed along edges 8. The plastics film constitutes a barrier layer through which oxygen permeates at a rate dependent on the film thickness to cause the chemical compound to change colour after a certain period of time. By forming a group of indicators using different chemicals or films of different thickness, a graduated time indicator may be produced, the chemicals in the individual indicators changing colour after the elapse of different periods of time. Suitable chemical compounds are leucomethylene blue, Paradone yellow G, or a mixture of scarlet and yellow dyes, compounds being absorbed in filter paper. The barrier layer may comprise polyvinyl chloride, polyvinylidine chloride, polyester, or nylon strips with an additional layer of polyethylene or polypropylene or single layer strips of plastics may be used. Sodium hydrosulphite may be absorbed in the filter paper to increase the time for the colour change and a humectant such as glycerol or ethylene glycol may be added.

Title: Multiple disc brake
IPC: F16D59/00
Filed: 1968-10-08
Abstract: 1,202,804. Disc brakes; one-way detents. INGERSOLL-RAND CO. 8 Oct., 1968 [5 Feb., 1968], No. 47701/68. Heading F2E. A multiple disc brake wherein the rotatable brake discs encircle and are engaged with a support includes a plurality of ring-shaped elements of rubber-like material, each element being located between a fixed brake disc and the support so as to engage the rotatable brake discs on either side of the fixed brake disc so as to cushion the engagement of adjacent braking surfaces during compression and to facilitate disengagement on release. The invention is shown as applied to a hoist 10. Operation.-With the lift hook 20, Fig. 1, stationary, a load thereon applies a torque to the output shaft 50, Figs. 1 and 3, in the clockwise direction as viewed in Fig. 3. This torque urges the planet gears 44, 46, in a clockwise direction and causes planet gears 44 to apply a torque to the large ring gear 54, also in a clockwise direction. The torque on the ring gear 54 causes the cam teeth 86, 90, to urge ring gear 54 and actuating element 82 towards the brake plate 80 to apply the brake. Simultaneously, sprag clutch 60 locks support 58 to output shaft 50. Thus sprocket 52 and hoist chain 18 are locked against movement. To lower a load, the hoist motor is operated to rotate drive shaft 26 and sun gear 30 in a clockwise direction; the sun gear 30 thereby rotates planet gears 44, 46 in a counterclockwise direction; in consequence the inter-engagement of planet gears 44 and large ring gear 54 drives the gear frame 32, and thus output shaft 50, in a clockwise direction and moves large ring gear 54 in a counterclockwise direction, thereby releasing the brake. As the lift hook 20 and its load are lowered, the load torque may over-run the motor torque, causing the brake to be applied; the brake may be alternately applied and released in this manner during lowering. To raise a load, the hoist motor drives shaft 26 and sun gear 30 in a counterclockwise direction; planet gears 44, 46 are thereby rotated in a clockwise direction, and gear frame 32 in a counterclockwise direction. Thus output shaft 50, and sprocket 52, are rotated in a counterclockwise direction. In consequence, sprag clutch 60 releases support 58 from the output shaft 50. Thus, through ring gear 54 has been moved in the "brake-apply" direction, the consequent closing-up of the brake discs has no effect on the output shaft 50. The resilient ring elements 92 e.g. of rubber cushion the shock of brake application, but allow the compression necessary for adequate braking action. The ring elements also act through the actuating element 82 to maintain constant pressure on the cam teeth 86, 90, and thereby prevent brake chatter. Upon release of the brake stack the ring elements facilitate separation of the discs and ensure uniform separation. Each ring 92 is located within the periphery of a fixed brake disc 62, but tightly encircles and grips the splined support 58 for rotation therewith. The rotatable brake discs 64 are splined to the support 58.

Abstract: 1,166,550. Zip , fasteners. B. F. GOODRICH CO. 19 Oct., 1967 [3 Oct., ,1966], No. 47719/67. Heading E2S. In a zip fastener of the kind in which the chain elements 13, 14 are, when closed, completely covered by sealing strips 30 and 34 of rubber or the like, these stripseach have an outer liner 32 or 36 of textile material bonded to the rubber. The slider (not shown) of such a fastener embraces the sides-of the sealing strips, and the presence of the liner both reduces slider friction and avoids damage to the sealing material.

An hydraulic damper 25, 27 can be provided. A safety pawl 89 is provided. A cam 79 acting on a switch 103 energizes the X-ray source 2 at the correct point in the rotation. An electrical circuit, Fig. 5 (not shown), provides for the operation of the device only when all the correct procedures have been carried out. The cassette itself need not be parallel to axis 7.
