Abstract: 878,559. Pistons. WELLWORTHY Ltd. July 18, 1960 [July 17, 1959], No. 24638/59. Class 122 (1). In an aluminium alloy piston wherein at least one of the compression ring grooves 3, 4, 5 is formed in a ring carrier insert 6 which is of harder metal than aluminium and bonded to the aluminium alloy, the mean diameter of the piston head at ambient temperatures increases from the top end of the head towards the gudgeon pin axis such that at normal working temperatures the head is substantially parallelaided. The grooves are machined so that their side walls are frusto-conical and inclined from the bottom of the groove towards the top end of the piston head at an angle of “ to ¥ degree to planes perpendicular to the axis of the piston. The insert may be bonded in the piston by the method described in Specification 599,684.

Patent GB-532413-A (GB)
Title: Improvements in or relating to fuses for electric circuits
IPC: H01H85/00
Filed: 1939-08-29
Abstract: 532,413. Fuzible cut-outs. PHILIPS LAMPS, Ltd. Aug. 29, 1939, No. 24815. Convention date, Sept. 1, 1938. [Class 38 (i)] A fuse comprises a conductor embedded in a solid mass of material which is an electric insulator but serves to cool the conductor, but which also interrupts the conductor if an excessive current passes. The fuse allows repeated overloading for short periods which allow the heat generated to be dissipated, but it breaks down if overloaded for a relatively long period when the heat developed is so great that the mass of material undergoes a change. The conductor may consist of a wire of nickel-iron alloy, and it may be coated with a precious metal such as platinum. The wire 3, Fig. 1, may be embedded in glass or artificial resin. When an excessive amount of heat is developed by the current through the wire, the glass softens and sags and its weight breaks the wire. The glass also may crack and expose the wire which oxidizes or burns. In another construction, shown in Fig. 3, the wire 7 is embedded in artificial resin 8 and a helical spring 9 is connected to one of the leads 5 and to the remote end of the resinous mass, the spring being compressed. If the heat generated softens the resin, the spring extends the mass 8 and breaks the wire. The fuse may be straight, as shown, or of any other suitable shape.

Title: Manufacture of animal food
IPC: A23K1/18
Filed: 1930-08-20
Abstract: A process for the manufacture of animal food comprises boiling red meat and fat, grinding the meat, mixing it with flour or other cereal to ensure cohesion of the finished product, adding sufficient liquid thereto to reduce it to a consistency that will permit of its being forced through a commercial can filler, adding whole, milled or cracked cereal or cereals and immediately introducing the product into a can before the cereal or cereals have completely absorbed the water, the can being finally sealed. After boiling, the meat may be drained and ground before adding liquid thereto.  Horse meat and fat may be used, and the added liquid may be the withdrawn meat liquor. Ground barley, broken rice, whole wheat and traces of garlic may be used.  After sealing, the cans are passed through an exhaust box at 180 DEG  F. for five minutes and then through a retort at 240 DEG  F. for two hours, after which they are cooled in running water.  The food may be served in slices, or minced.

Abstract: 1466376 Steering column mountings CAM GEARS Ltd 6 May 1974 [24 May 1973] 25029/73 Heading B7H A breakaway mounting for a collapsible steering column includes two members adapted to be mounted on the vehicle and the column respectively, a holder on one member embracing a part of the other and the holder being deformable to allow disengagement of the members on vehicle impact. In one embodiment, Fig. 2, the holder 12 is formed by the metal plates 10, 8 mounted on a jacket 4 of the column, and surrounds a metal pin 20 of a connector 14 mounted on the vehicle, the pin 20 being positioned by a dowel 22. On frontal impact the inner column 2 telescopes and the force exerted on the jacket 4 causes the holder to open by deformation and release the pin. In another embodiment (Fig. 3, not shown) the pin and connector are integrally formed as a plate with a cylindrical enlargement along one edge. In a further embodiment (Fig. 5, not shown) the holder may be formed from a plastics bracket moulded on the column jacket. In yet another arrangement (Fig. 7, not shown) the holder is formed by a single spring steel U-clip, or a number of such clips, carried by a bracket on the jacket.

Title: A process for preparing foamed thermoplastic polymers
IPC: B29C44/34
Filed: 1964-06-17
Abstract: A process for producing a foamed thermoplastic polymer comprises mixing finely divided solid particles of a thermoplastic polymer and a nucleating agent with a volatile blowing agent, increasing the pressure and heating the particles to melt them while maintaining the blowing agent in intimate contact with the polymer and then extruding the molten mixture through a die, thereby releasing the pressure of the mixture to foam the polymer. The polymer may be a polymer or copolymer of monomers such as ethylene, propylene, butylene, styrene, a -methylstyrene, methyl methacrylate, ethyl- or butyl acrylate, vinyl acetate, vinylidene chloride and vinyl chloride.  The nucleating agent may be a silicate or finely divided silica powders or bentonites.  In an example, powdered isotactic polypropylene, finely divided silica powder and isopentane are used to produce a foam having a density of 45 g./l. and a homogenous cell size below 0.3 mm.

Title: Improvements in or relating to the moulding of ceramics
IPC: B28B1/24
Filed: 1951-10-30
Abstract: 706,728. Injection-moulding ceramic material; refractory compositions. BENDIX AVIATION CORPORATION. Oct. 30, 1951 [Nov. 28, 1950], No. 25367/51. Addition to 671,371. Classes 22 and 87 (2) A ceramic article is made by injecting into a mould a mix comprising ceramic material, thermoplastic resin, one or more waxes vaporising between the temperatures of 300‹F, and that at which the resin is removed and an oil vaporising below 300‹F., and after moulding heating the moulded article at progressively raised temperatures to vaporise first the oil, then the wax and finally to remove resin and fire the article. Thus, the moulded article is removed from the mould and heated at 125‹F., rising in steps to 450‹F. At 125-300‹F. the oil comes off, thereby forming minute.pores in the article, 'then the wax vaporises between 300‹F. and the temperature at which the resin is removed, viz. 400-450‹F., the vaporised wax passing through the minute pores made by the vaporised oil, and finally resin passes off, probably in the form of decomposition products. At this heating stage only 75 per cent. of the resin may be removed, the remainder being removed by the subsequent firing. More than one oil and wax, vaporising in sequence, may be used. The ceramic material may be composed of tri-calcium penta-aluminate and silica in the proportions stated in U.S.A. Specification 2,423,958 or the material specified below. The oil may be a light oil, the wax may be beeswax, carnauba wax, "Acrawax" (a synthetic wax) or any animal vegetable or mineral wax having a suitable vaporising temperature, and the resin may be polystyrene. In an example 76.92 per cent. by weight of a 200-mesh non-uniform particle size ceramic material containing 88 per 'cent. of Al2O3, 10 per cent. of 3CaO, 5 Al2O3, 2 per cent. of SiO2 and some traces of MgO as impurity is mixed with 13.34 per cent of polystyrene powdered to 200 mesh, 6.92 per cent, of light oil vaporising between 125 and 300‹F. and 2.82 per cent. of beeswax which vaporises above 300‹F. This mixture is ground and moulded cold or at temperatures up to 150‹F. into circular preforms 17. When a preform is to be injectionmoulded it is heated by high frequency to 300- 350‹F., transferred quickly to a pressure chamber 15 and ejected therefrom through sprue 14 into a cold mould 12 (as shown, a spark plug mould having a removable core 13, but it may be a mould for making elbow or thread guides). The mould has air vents remote from the injection inlet. The article is taken from the mould and heated as described above.
