Title: Apparatjs for the treatment of aggregates prior to washing
IPC: B02C4/30
Filed: 1972-06-15
Abstract: 1446707 Roller mills R W WILEMAN (ENGS) Ltd 14 Sept 1973 [15 June 1972] 27941/72 Heading B2A  Comminuting apparatus comprises a pair of parallel resilient - surfaced contra - rotatable rollers 7,8 preferably having intercalating elastomeric discs or flanges 15. At least one roller 8 may be resiliently biassed or free to swing away from roll 7. The rollers may be driven at different speeds. As described, roller 7 is beltdriven by a motor 10 and gearbox 12. The gap between the rollers is determined by a stop not shown. The flanges or discs 15 may have shapes shown in Fig. 3. In operation hard material and small clay lumps pass through unaffected due to the resiliency of the discs 15, and aggregates can thus be fed to a normal washing/ scrubbing plane. In modifications, both rolls may be power driven, the speed of one or both rolls may be variable and the discs 15 may be of plastics e.g. polyurethane. The rolls could also comprise sets of low pressure pneumatic tyres. A feed hopper 6 is provided.

Title: Improvements in latch and safety catch mechanism for lid type automobile hoods
IPC: E05B65/19
Filed: 1939-10-17
Abstract: 538,340. Car bonnet fastenings. BASSICK CO. Oct. 17, 1939, No. 28035. Convention date, Oct. 17, 1938. [Class 44] A fastening for an alligator type of hinged lid. on a motor-car bonnet, and providing an automatic safety catch which can be operated to effect a tight closure, comprises a torsionally resilient rod 27 transversely mounted for rotation in heavy loops 26 shown as secured to a transverse sheet-metal reinforcing beam 22 secured in the lid 10, the rod being cranked at 29 to provide off-set ends 30 which co-operate with fixed catch members 17. The rod has a central upwardly cranked portion 28 connected by a link 38 with an operating handle 47, shown as an ornament, pivoted at 49 to a bracket 45 secured inside the lid. The upper end of the link is pivoted to the handle at 57 and is bent as shown so that, in fastening, the link can pass over the dead-centre position unobstructed by the pivot 49. The lower end of the rod passes through an aperture in member 22 and is slidably guided in a lug 36 stamped out of the aperture and also forming an abutment for the lower end of a spring 41 which urges link 38 upwards. The fixed members 17, which are mounted on and off-set from end walls of an air baffle 12 mounted in the engine compartment have inclined surfaces 18, 20 separated by a hooked nose 19. The upper ends 21 of the members are inwardly curled and co-operate with the edges of apertures in member 22 to centre the lid and prevent side play. When handle 47 is raised to effect release, moving pivot 57 clockwise, Fig. 1, rod 27 is rocked anti-clockwise to move its ends 30 clear of members 17. When the handle is released after raising the lid, spring 41 restores the parts to an intermediate position in which, when the lid is closed, the ends 30 slide over surfaces 20 of members 17 and snap behind hooks 19 under action of the spring, thus automatically giving a safety-catch action. When handle 47 is fully depressed to secure the fastening, the ends 30 are pressed resiliently against surfaces 18 of members 17 under torsional deformation of rod 27, link 38 passing over the deadcentre position to retain the lid tightly closed. A modification is described in which members 17 are carried by the lid and the rod 27 by the engine compartment. An operating rod, slidable horizontally and connected to crank 28 by a link, extends through the front of the engine compartment and terminates in a knob by which it may be pulled outwards against the action of a spring to effect release. In other essentials this modification is an inversion of the form described above.

Filed: 1960-08-15
Abstract: In the separation of straight- or branched-chain hydrocarbons from hydrocarbon mixtures by adduction with urea or thio-urea, the mixture of adduct and non-adducted hydrocarbon is introduced into an intermediate portion of a washing zone where the downward flowing adduct is contacted with an upward flowing stream of the original mixture; washed adduct is removed at the bottom and non-adducted hydrocarbon mixed with the original mixture is removed at the top.

Abstract: 1467609 Making tyre treads GOODYEAR TIRE & RUBBER CO 7 July 1975 [19 July 1974] 28470/75 Heading B7C [Also in Division B5] A method of forming a tread on a pneumatic tyre comprises placing unvulcanized rubbery tread material 25 on the outer periphery 22 of the tyre, covering the tread material with an elastic membrane 26 having a smooth inner surface contacting the outer surface 38 of the tread material, applying heated fluid under pressure to the outer surface of the membrane to compress the tread material 25 on to the tyre and to vulcanize the material thus forming a tread whose outer surface 38 is smooth, and finally grooving the surface 38 to form a tread pattern. The unvulcanized tread material may be applied in the form of a strip coiled around the tyre in accordance with the desired transverse contour of the tread. In the method as illustrated the tyre, with tread material 25 applied and covered by the membrane 26, is placed in a cavity 31 defined by a two-part apparatus 28 such that the membrane is clamped between the sidewalls 14, 15 of the tyre and the sides 32, 33 of the apparatus. Pressure, e.g. 150 p.s.i., is then applied to the inner surface of the tyre in the tread region, either by use of an inflatable curing bag 35 and support rim 36 inserted into the tyre or by mounting the tyre'on a rim 20 and inflating it. Thereafter the heated fluid under pressure, e.g. steam at 65 p.s.i. and 200-350 F., is admitted to a chamber 34 defined by the apparatus 28 and the membrane 36. Wicking cloth 27 may be provided to enable escape of gas from between the membrane 26 and tread material 25 during vulcanization. Circumferential grooves may be formed in the vulcanized tread by rotating the tyre whilst applying a hand-held or machine operated grooving tool (39) (Fig. 2, not shown) against the tread. The method may be used to form a tread on an aircraft tyre built and vulcanized without a tread, or to retread a worn aircraft tyre.

Treatment with the acetylating mixture may be effected at from -10 DEG  to 45 DEG C. The product may be purified by washing with ether, and pouring into an alcoholic sodium acetate solution which is then neutralized by the addition of a dilute sodium carbonate solution.  The product is then drained off, rinsed and dried.  Belgian Specification 553,396 is referred to.

A latch for a suitcase comprises a catch 1 adapted to be fastened to a suitcase lid 2 and a latch assembly adapted to be fitted to the body of the suitcase, the latch assembly comprising an operating device III adapted to be fitted externally and a retaining device II adapted to be fitted internally of the suitcase, the operating device comprising a slide 15 and a pin 30 which projects into housing 8, 9 of the retaining device, and which engages a retaining bolt 10 which is retained in the releasing position by a spring 11 and of which one end portion 32 is hook shaped and in use engages a free end portion 6 of the catch 1 in the fastening position. In one embodiment, Figs. 1 and 3, the bolt 10 is pivotally mounted on a collar 14 of the housing 8, 9 and is held in its releasing position by a lug 13 thereon engaging in an indentation 12 of the spring 11. The bolt is alternatively held in its fastening position by the lug 13 engaging an inclined portion of the spring. The spring 11 is so shaped that movement of the bolt from its releasing to its fastening position requires more force than the reverse movement. In a second embodiment, Fig. 6, the bolt 10 is slidable and is urged to its fastening position by a spring 31. The spring 11 has an indentation 12 which in the releasing position of the bolt 10 engages in a hole 13 in the housing to make it difficult for the bolt 10 to be slid to its fastening position. In each embodiment the operating device III comprises a plate to which the pin 30 is rivetted, the plate being slidably mounted on a baseplate 19 by passing tabs drawn out of the baseplate through slots in the plate and bending over the tabs. Sliding of the plate relative to the baseplate is prevented by a conventional locking device. In each embodiment as the bolt 10 moves to the releasing position from the fastening position a shoulder thereof engages the catch 1 to positively urge this section out of the housing 8, 9. The latches can be used for right hand or lefthand operation by reversing the bolts and repositioning the springs accordingly, and the catch 1 and housing 8, 9 are cranked so that they can be used on a suitcase having closure frames 35.
