Title: Improvements in or relating to thermostatically-controlled electric heating equipment
IPC: H01H37/00
Filed: 1944-04-25
Abstract: 586,924. Thermal switches. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and ROSEBY, P. N. April 25, 1944, No. 7643. [Class 38 (v)] A thermal switch for protecting boiling plates having a loading such that dangerous temperature-rises may occur when the plate is energized but not in use, has a bimetal strip 18 heated by radiation from the underside of the plate 10 acting through apertures 20, 21 in the base 13. The strip is connected at its free end, through a deadcentre spring 26 passing through a hole in a bracket 28, to a U-shaped contact blade 29 resting in V-notches in the bracket 28. Radiant heat passing through the preferably-adjustable slot 20 causes the strip 18 to bend away from the base 13 and move the blade 29 away from contact 31 against a stop 41. A second, similarly-acting, bimetal strip 19, tensioned by a screw 27, retards the action of strip 18 by rotating their common support 24 clockwise when heated by radiation through the aperture 21, which may be adjustable by a slide 22. Conductors 38, 39 ensure good connection between the blade and bracket 28. The switch may be operated in conjunction with the control switch described in Specification 565,996. Either or both of the thermal strips may be heated additionally by conduction. The boiling plate may be as described in Specificaton 586,920, [Group XI].

Filed: 1924-03-28
Abstract: 231,000. Invernairn, (W. Beardmore), Lord, and Chorlton, A. E. L. March 28, 1924. Cylinders receiving liquid fuel. - In an engine having a combustion chamber B formed in the cylinder head, a sleeve valve H controls the cylinder admission and exhaust ports E, F and G. The admission ports E, F form a ring around the cylinder; one of these ports F, admits hydrogen to the combustion chamber B, whereas the remainder, which are similar to E, supply air to the cylinder, at a point below the passage separating the cylinder from the combustion chamber. The air mixes with the hydrogen during the compression stroke, and the weak mixture thus formed is ignited by a sparking plug J. The combustion initiated in this way ignites liquid fuel injected through a nozzle D. Instead of using hydrogen, the ignition may be initiated by a hot plate, or by the heat of compression, or by a separate igniting fuel injected through a subsidiary nozzle. Specification 221,254 is referred to.

Filed: 1916-06-09
Abstract: 101,939. Rushton, G., and Lacy, L. R. June 9, 1916. Tool arms and mountings.- The sound-boxes are arranged to play either lateral-cut or vertical-cut records without adjustment, by so pivoting the styluscarrier to the sound-box that the stylus may move either vertically or laterally, either movement causing the diaphragm lever to oscillate in a direction normal to the plane of the diaphragm. Fig 1 shows the sound-box in elevation, and Fig. 2 is a section on the line 2-2. The upper part a of the stylus bar is connected at one end to the diaphragm and is pressed against knife-edges b on the face of the sound-box c bv means of a set-screw and spring. The lower end of the part a has a curved lug h, which engages a V-shaped recess j in the stylus-carrying member k, which has an upwardly-pointing pivot or knifeedge, pressed into a shallow socket on the soundbox rim by screws p. The heads of these screws engage a cross-piece m on the carrier k, and springs are interposed between the cross-piece m and the sound-box c. A smooth abutment r supports the carrier k from behind. Vertical movements of the stylus are transmitted to the diaphragm through the carrier k, lug h, and lever a by direct pressure, while lateral movements of the stylus cause the V-shaped notch in the carrier k to slide on the lug h and thus oscillate the diaphragm lever a by a cam action.

Title: Vulcanisable rubber compositions
Inventor: COULTER DAVID JAMES BRYANS
IPC: C08L21/00
Filed: 1956-03-16
Abstract: A natural or synthetic rubber composition contains a minor amount by weight of polythene of specific gravity more than 0.92. The rubber and polythene may be blended at a temperature equal to or greater than the melting point of the polythene.  Preferably, the weight of the polythene is between 10 and 35% of the combined weight of rubber and polythene.  The synthetic rubber may consist of a butadiene-styrene or isoprene-butadiene copolymer.  When the composition is vulcanized it has high tensile strength, modulus, and elongation at break, resistance to ozone attack, and electrical resistivity.  It is thus useful in the manufacture of electric cables, tyres, and microcellular soles for footwear.  In one example, a microcellular material is prepared by vulcanizing in a press a composition containing (in parts by weight) isoprene-butadiene copolymer 100 and polythene 30, or butadiene/styrene copolymer 100 and polythene (of specific gravity 0.94) 10, or pale crepe 100 and polythene 15, calcium silicate 60, china clay 30, purified wood cellulose 15, petroleum jelly 10, and small amounts of zinc oxide, titanium dioxide, sulphur, accelerators, antioxidant, and, as blowing agent, N,N1-dinitrosopentamethylene, with or without p-dinitrosobenzene.
