Abstract: 976,074. Packages. J. A. BRUCE. Aug. 28, 1963, No. 34075/63. Heading B8C. A package for cans has at least two of the cans in side-by-side relationship, at least a further two cans stacked in end-to-end relation with the first two cans with a cushioning device between the contacting ends of said stacked cans, said device having a contour conforming to the end faces of the cans, and a heat shrunk film encasing the cans thus drawing them into contact with the cushioning device. In one embodiment the cushioning device is an element comprising end portions 8 and 9 and sections 11 and 12 cut to conform to the contours of the ends of the cans. The portions 11 and 12 are folded into contact and inserted between the cans, the portions 8 and 9 being bent to lie against the side faces of the cans for use as stiffeners as well as for display purposes. The package is then wrapped in heat shrinkable material such as polyester film. In other embodiments the cushiong device is formed without the portions 8, 9, the member 11 being of a cushioning material with or without circular cut-out portions, Figs. 4, 5 (not shown). Specification 923,048 is referred to.

Abstract: 1,160,779. Sheet forming. IMPERIAL CHEMICAL INDUSTRIES Ltd. 12 July, 1968 [25 July, 1967], No. 34171/67. Heading B5A. In a sheet forming apparatus, for particular use in the production of articles such as bath tubs from relatively thick sheet material, a series of blanks are heat softened in an oven successively transferred from the oven to a differential pressure forming station, and finally formed to the desired shape at the station. In the embodiment shown in the Figure, polymethyl methacrylate blanks are transferred from a stack 11 by a suction device 10 and a roller conveyer 12 to a forced convection oven 13 in which they are collectively heat softened. After its desired residence period each blank is transferred from the oven over roller conveyer 14 to a station 24 at which bath tubs are drawn using a plunger assisted vacuum forming mould 23. The drawn tubs are subsequently removed from the mould, clamped over forms carried by conveyer 16 and passed between edge trimming saws 31 and 32. In an alternative embodiment (see Fig. 2, not shown), the blanks are suspended vertically from a closed loop track and are transferred first to a heating oven, then to a plunger assisted vacuum forming station, and then to a take-off station. A cleaning station, at which the blanks are washed scrubbed and then dried, may be located in front of the oven in each embodiment.

A valve comprises a chamber 14 having an inlet 16 controlled by a valve 20, and an outlet 36, connecting with an outlet pipe 72, controlled by a float-actuated valve 42. Valve 42 comprises a jumper having an upstanding stem 44 freely located in a bore 46 of a member 48 connected by ball-shaped element 50 to one end of a float arm 56. Downward movement of the float raises the member 48 and allows the pressure of fluid in the chamber 14 to lift the valve 42. Upward movement of the float causes member 48 to force the valve 42 on to its seat and cut off flow. If the supply at inlet 16 fails, valve 42 will fall and prevent back-flow.

The socket, which is internally shaped to fit closely around substantially the whole working surface of the ball and has one end closed and the other end formed with a mouth of smaller diameter than the ball, is made of synthetic plastic material which is sufficiently resilient to enable the mouth to be stretched to permit entry of the ball and is inserted into an outer supporting housing after entry of the ball. The housing also prevents the expansion of the mouth which would be necessary to withdraw the ball. In the embodiment shown in Fig. 1 the housing 1 is formed integrally in a stub axle carrier 2 and the socket 5 is retained therein by a ring 6 or a circlip. In a modification, Fig. 3, the housing comprises an outer part 1c which is screwed on to an internally dished extension-lb of the carrier 2 and is secured thereon by a tab washer 9, and in a further modification, Fig. 4 (not shown) the housing comprises an externally screw-threaded cup-shaped part which is screwed into an extension of the carrier 2. Alternatively the housing is formed of two outwardly flanged cups, bolted together with the flanges abutting, or may be provided by an aperture in one end of a rod forming part of a steering assembly. In any embodiment a small recess may be formed around the inside of the housing to accommodate excess material of the socket if the latter is preloaded. The socket may be formed in more than one piece. A dust excluder 8 is provided.

A wrapper assembly includes a U-shaped frame 14 withdrawable for repairs axially of a driven mandrel 12 along rails 20, 21. The mandrel may also be withdrawable. A pair of arms 23, pivoted at 22 to the frame 14, each carry a driven wrapper roll 24 and a guide plate 25 and are urged by piston and cylinder means 26 towards the mandrel and are retractable therefrom by the same means. Strip 71 to be coiled is fed over driven rollers 47 of a roller table, carried by columns 46 which separate pits, in each of which a coiler is mounted, and is deflected by pinch rolls 50, 51 over a guide plate 55, down a guide 38, under a roller 40 and guide plate 41, rockable about the roller by linkage connecting it with the upper arm 23, and over a plate 45, on the lower arm 23, to the mandrel 12. After the first few coils have been wound the wrapper rolls 24 are retracted from the mandrel. When the strip has been fully coiled rotation of the mandrel and wrapper rolls is stopped and the upper pinch roll 51 is raised, by motor-driven screw-and-nut mechanism, and the guide plate 55 is raised by a toggle 56 so that strip is now directed over the rollers 47 above the coiler to the next coiler.

Title: Improvements in or relating to processes of preparing soya beans for consumption, and the products resulting therefrom
IPC: A23L11/30
Filed: 1935-12-23
Abstract: To prepare soya beans for consumption they are soaked in water to bring their moisture content up to and preferably above 20 per cent of the dry material and are then subjected to a temperature above the boiling point of water, but below 400 DEG  F., preferably 325 DEG  F. for a short time: the temperature is then reduced and the drying continued, preferably at a temperature below the boiling point of water.  The soaking of the beans may conveniently be for about 15 minutes, the water being at a temperature of 100 DEG  F.  The water used may be drawn off and re-used in treating subsequent quantities of beans, thus keeping the loss of the soluble constituents of the beans low.  The beans may be whole, broken or pulverized.  In a modified treatment, the beans after soaking and heating are dried till they retain 4-6 per cent of moisture; they are then ground, heated to 200-220  DEG  F. and then treated to expel the oil down to 7-8 per cent, the ground beans being kept at relatively low temperatures during the extraction of the oil. The ground beans are then cooled by spreading out so as to expose a large surface to the air.

An integrated circuit is made by diffusing acceptor impurity into a face of an N-type body to form first and second P regions, forming an N-type epitaxial layer over the diffused regions. diffusing further acceptor impurity into the layer to form a P zone extending to one of the buried P regions to isolate part of the N layer as a collector zone and another zone extending to the second P region, performing a third acceptor diffusion to form a base zone within the collector and finally a donor diffusion to form an emitter zone and a collector contact zone. In the embodiment six inclusions 16a-16f of P- type, 0À7 mils deep, are first formed by oxide masked diffusion of boron into a face of a 10-20 ohm cm. phosphorus-doped N-type silicon wafer lying 3-5 degrees off a 111 crystallographic plane. Arsenic or antimony is diffused into part of one of the inclusions to form N+ zone 22, after which the masking is removed and a layer of antimony-doped silicon deposited epitaxially from a silicon tetrachloride-hydrogen reaction. Then boron is diffused in, first to form heavily doped regions 26a-26f and then to produce shallower regions 28a, 28b, 28d and 28e. Finally N+ inclusions 30-36 are formed by phosphorus diffusion.
