Abstract: 518,398. Switchgear structures. SWITCHGEAR & COWANS, Ltd., and UPTON, A. Sept. 26, 1938, No. 27974. [Class 38 (v)] The figure shows the inspection-position of a vertically-withdrawable circuit-breaker which is put in the operative position by operating the lowering-gear j to bring the top plate i on to the tank l; the supplementary side brackets m are then removed from sockets n in the side-arms f, which, when the breaker has been wheeled into place, are then brought beneath the projections h, and the gear j operated to raise the arms f in the guides g. The tank may have wheels, but, as shown, a truck b is employed and can be removed to give place to a plug-in potential or current transformer. Instead of brackets m, the attachment arm supporting the breaker in the operative position may be swung outwards through 180 degrees about a vertical axis so as to support the top plate also in its withdrawn position.

Abstract: 1426122 Attachment of linings to brake shoes H KUBLBECK 14 June 1973 [20 June 1972] 28427/73 Heading B5N [Also in Division F2] A brake lining and a shoe have their cooperating surfaces covered with a hardenable adhesive and dried, one of the two components being then exposed to a solvent vapour to obtain a tacky adhesive surface, the lining and shoe then being pressed together by a clamping device and introduced into an oven for adhesive hardening. After adhesive application and drying the linings or shoes are fed along a flat conveyer in two rows through a slot in a tank which contains the solvent in a trough, the conveyer being just above the solvent surface for vapour penetration. The components are then fed out of the tank through a slot after 20 to 40 minutes, whereupon they are transferred manually or automatically to a squeezing assembly. Alternatively, the components are fed on to an inclined conveyer, Fig. 5, which is supported inside the tank 5 on a grate 35 or they are placed on a grate which is lowered into the tank a cover thereof being placed in position during solvent action. The squeezing assembly, Fig. 4, has a plurality of clamps with jaws 15, 17 shaped to conform to the shoes and linings and these are spring-biased to open, and are closed by rollers 23 coacting with the cam surface of a fixed cam 22. The components are inserted at A, the subsequent squeezing pressure being at 12 to 15 kg./cm.<SP>2</SP> for 4 to 6 seconds.

'enter the bottom of a fractionating column from which condensates are taken off at different levels, cooled below 100‹C. and returned in part as reflux to a point in the column lower than that from which they were removed. Tar from a tank 5 is pumped through a vapourizing coil 8 in a furnace 3 into a still 2 to which steam superheated in a coil 11 is also led. The vapours produced are led through a pipe 17 into a tower B provided with plates 19, 20 from which condensates are removed through lines 22, 23 to coolers 26, 34 and receivers 28, 35, from which part of the condensate is returned as reflux through lines 30, 37, while the remainder is removed to storage tanks 29, 36. The top of the column is maintained aoove 100‹C. so that the steam passes off with vapours through a pipe 39, cooler 40, to a receiver 41, where water is separated by decantation, the light condensate passing to a receiver 45, from which it is recirculated in part through line 46 as reflux. In the distillation of crude tar the products may be fractionated to recover pitch, anthracene oil, middle oil containing raphthalene, phenols, cresols (from which the naphthalene may be removed by crystallization) and a light oil boiling up to 180‹C.

As shown in Fig. 1 compressed air or gas from the explosion chamber of the engine 9 is supplied through a check valve 14 and pipes 11 10 to a tank 8, from which it can be delivered to the brake cylinder 20 and clutch control cylinder 69 through control valves 17, 70 and pipes 19, 71, respectively. The brakes can be independently operated from a foot pedal 7 by means of a rod 30 acting on a crank 27, whilst the clutch shaft 5 can be rocked either by the piston rod 73 of the cylinder 69 or by the clutch pedal 4. Each control valve 17, 70, as shown in Fig. 2, comprises two chambers 31, 32, connected respectively to atmosphere at 38, and to the brake or clutch cylinder at 19, and a diaphragm 33, having a central aperture through which passes a tubular member 48. A cylindrical valve 52 projecting into the member 48 is secured to a second valve 57 controlling the admission of compressed air at 60. In the position shown, the diaphragm occupies its central position, in which the valve 57 is held seated by a spring 56, and the valve 52 is open, so that the brake cylinder exhausts through the member 48 and pipe 38. To apply the brake, a spring 47 is compressed by a hand lever 40, whereby the diaphragm is depressed to close communication between the chambers 31, 32, and the valve 57 is opened to supply the cylinder with compressed air. In a modified form of control valve, the diaphragm is replaced by a piston working in a cylinder, the arrangement and operation of the valves 52, 57 being, however, unaltered.

Abstract: 914,018. Magazine discharge. SCHWEIZERISCHE INDUSTRIE-GESELLSCHAFT. Aug. 22, 1960 [Aug. 25, 1959], No. 28920/60. Class 78 (1). [Also in Group XVII] A device in a packaging machine for assembling various sizes of biscuit stacks comprises a reciprocating ejector 10 removing biscuits from a shoot 2, the line of stroke of the ejector being altered by cam means to vary the number of biscuits removed at every operating stroke. The ejector 10 is reciprocated by crank means 21 and is supported at 11 by a lever 8, the lever being pivoted at 9 and oscillated by an interchangeable cam 14. The lever is also connected to a shoot opening restrictor 4. As shown, the ejector removes two biscuits while the lever 8 follows parts d and e of the cam and is lowered together with the restrictor by the cam peaks a, b, c on the return strokes, Fig. 7. When the part f is effective, the ejector has a lowered line of advance and removes only one biscuit. The five biscuits are received on a table 34, lowered after each stroke, and finally ejected by a pusher 38 on to a conveyer 40 taking them to the packaging position. Variable-speed gears are interposed between the cam and crank drives for use when the cam is changed. Several shoots may supply biscuits to a common stacking means. The feed may be checked by the engagement of a latch 41 with the lever 8 when the highest peak c is effective. This may be automatic and dependent on means monitoring the biscuit supply.
