Patent GB-440776-A (GB)
Title: Improved process for making hollow bodies
IPC: B29C71/02
Filed: 1935-04-30
Abstract: Pipes, tubes, and other profiled hollow bodies which may be used as substitutes for porcelain, earthenware or quarts vessels are prepared by winding skins, films or webs made from compositions containing polyvinyl chloride in a solvent-free state under tension over heated rollers onto a winding core and welding together.  Pores, bubbles and air occlusions may be removed by treatment of the wound body in hot water under pressure.  Suitable compositions include mixtures of polyvinyl chloride with polyacrylic acid esters, or polyvinyl acetate which may be subsequently halogenated, or chlorinated polyvinyl chloride with or without the addition of plasticizers such as triphenyl phosphate, lubricating agents such as octadecyl alcohol or wool fat alcohols and fillers such as titanium white, zinc white, lithopone, cellulose, artificial or natural resins, caoutchouc or hydrocaoutchouc.  In an example, an interpolymer of vinyl chloride and acrylic acid methyl ester is made into a film and then wound into tubes.  Specification 429,480 is referred to.
Patent GB-799139-A (GB)
Title: An improved automatic drinking trough for animals
IPC: A01K7/06
Filed: 1957-04-23
Abstract: 799,139. Animal feeding devices. BERTAZZONI, A. April 23, 1957 [Jan. 22, 1957], No. 12854/57. Class 5(2). [Also in Group XXIX] An animal drinking trough comprises a water feed pipe 2, a nose-piece 6 pivoted within the trough and a resilient roller 3 mounted on a spindle 4 carried by a bracket 12 on the nosepiece 6, which normally seals an aperture 1 in the pipe 2 and may be both moved from its seating and deformed under pressure from the nose-piece so allowing water to enter the trough, the release of the pressure on the nosepiece causing the roller to re-seal the aperture 1. The nose-piece, pivoted at 5, normally holds the roller against the aperture 1 by its weight. To increase the flow of water, the aperture 1 may be widened by filing. The pipe 2 is externally threaded at 7, and on this thread a control bush 8 is screwed, providing a corner 9 to act as a stop for the nose-piece. By adjusting the height of the bush 8, the traverse of the nosepiece may be limited, thereby reducing the extent of pressure on the roller 3 and consequently the extent to which the aperture 1 is uncovered. In this way the water inlet may be entirely disconnected from the action of the nose-piece. A locking device 10, engaging at its lower end with a lug 13 on the pipe 2, prevents an animal from raising the nose-piece. When the nose-piece is depressed the lower end of the member 10 slides down the pipe, under gravity, as shown in Fig. 1.

Filed: 1940-08-12
Abstract: 540,704. Shoe-filling machine. POCHIN, H. W., DOVE, G. H., and BROMLEY, J. H. Aug. 12, 1940, No. 12896. [Class 17 (i)] A machine for spreading and compressing the plastic filler used in filling the cavity in a shoe bottom formed by the upper when lasted over the insole comprises a power-operated member which is caused to travel with a rolling motion over the surface of the shoe bottom. A sector l having an electrically heated platen n of brass secured thereto is pivoted at k to a link i actuated by a crank h, the pivot k being guided in a track m. The sector l is also pivoted to a link p secured at its other end to the frame of the machine. The crank is driven by gearing from an electric motor and performs one revolution for each depression of a treadle u. A support for the fore part of the shoe is spring supported, its uppermost position being adjustable. The support engages the toe end and instep of the shoe and rests on rollers and a turned boss so that the shoe is self-adjusting to the platen. The pressure may be varied as the rolling action progresses over the shoe bottom, e.g. by making the face of the sector eccentric to its pivot.

Abstract: 1493076 Viscous dampers SONY CORP 27 March 1975 [4 April 1974] 13041/75 Heading F2S [Also in Division G5] A turntable mat comprises a lower circular member 1b and an upper annular shaped member 1a both formed of a flexible material such as rubber which with edge portions 1c 1d define an annular sealed space 3 which is at least coextensive with the grooved portion of a standard record. The space is filled with a viscous fluid such as silicon oil, or Fig. 4 (not shown) with a viscous fluid in which solid particles, e.g. glass beads are uniformly dispersed, or Fig. 5 (not shown) with an absorbent, e.g. sponge material impregnated with the viscous fluid. In a further arrangement, Fig. 6 (not shown), the annular space is divided up by circular or radial partitions into a number of spaces each of which is filled with the viscous fluid. The mat reduces record vibration by providing a firm base for a record even if it is warped and reduces the transmission of vibrations from the turntable drive to the record.

Abstract: 208,506. Svenska Ackumulator Aktiebolaget Jungner. Dec. 12, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Cases.-A number of storage battery cells 1 particularly of the alkaline type having conducting containers are insulated from one another by being mounted in a wood &c. frame 5, 4, insulating partitions 2 between the cells being embedded at their ends in sealing material 6 closing the top and bottom ends of the frame. Each cell is suspended on insulators 3 fitting into the walls 4 of the frame 5. The partitions 2 may be formed from a single sheet of material bent into zig-zag form, or each cell may be partly or wholly surrounded by a separate sheet which may be wound round the cell. In an alternative construction each cell is surrounded by a compound which is moulded on to the cell. The connectors 7 between the cells are embedded in the sealing material 6. The battery is assembled by standing the frame on one of its ends 5, the opposite end being open. The insulating sheet 2 and the first cell 1 are then placed in position. The sheet is then bent round the edges of the cell and the second cell placed in position and the process repeated. When the last cell is in place the other end 5 of the frame is secured in position and the whole turned upside down and insulating composition poured over the bottom of the cells. When this has set the battery is placed in the upright position, the connections 7 fixed and the composition poured over the top of the cells, the filling and vent plugs projecting through the seal. An additional bottom may be fixed to the underside of the frame and the top protected by a lid.
