Filed: 1936-11-13
Abstract: Spark-plug insulators of good heat conductivity are made by shaping a silica-free mix comprising finely ground alumina and one or more of the oxides of calcium, strontium, barium, zinc or cadmium and firing at a temperature corresponding to Orton cone 30-35.  The oxides of calcium, strontium and barium may be replaced by the corresponding carbonates, particularly when the mixture is moulded with the aid of water.  It is stated that the product consists of a mixture of corundum and the corresponding aluminate.  Preferably, 3-10 per cent of the oxide are added to the alumina; in addition fluxes and the oxides of cerium and tantalum as described in Specification 484,315 may be added to the mix.  The mix may be moulded with the aid of temporary binders such as a synthetic resin or with hydrochloric acid.  In an example, alumina, precalcined at 1200 DEG  C., is ground until the major portion comprises particles of an average size of 5m , the ground alumina is mixed with barium carbonate, a small quantity of a synthetic resin of the phenolic condensation type and water, and then granulated; the granules are particularly dried, moulded into the desired shape under heat and pressure, and the articles finally fired.

Abstract: 1,103,734. Fluid-pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 4 July, 1966 [22 July, 1965], No. 31209/65. Heading F2F. In a brake distributer, particularly for compressed-air brake systems of rail vehicles, of the type having a pressure-sensitive pile whereby brake pipe pressure is balanced against a control reservoir pressure to obtain a corresponding brake cylinder pressure, a quick service valve 11, 16 is operated by movement of the pile 1, 2 13, following engagement of flange 21 or 22 of valve element 16 with a pivoted latch 14 whose pivotal movement is controlled by brake cylinder pressure acting on a diaphragm 10, the arrangement being such that the latch is completely withdrawn when brake cylinder pressure exceeds a first higher predetermined value, e.g. 5 lbs. per square inch, to prevent operation of the quick service valve, and is partially withdrawn when brake cylinder pressure is between the first predetermined value and a second lower predetermined value, e.g. 1 lb. per square inch, so that operation of the quick service valve is prevented when the brake pipe pressure is varied at less than a predetermined rate but is allowed, owing to the engagement of the latch 14 with flange 22, when brake pipe pressure is varied at a rate higher than this. When brake pipe pressure is below the lower predetermined value, i.e. at the commencement of braking, the latch 14 is positioned to engage the flange 21, so that immediate operation of the quick service valve occurs. The diaphragm 10 operates, in addition to the latch 14, a ball valve 7 controlling communication, via a restriction 9, between the control reservoir and the brake pipe, the valve 7 being open only so long as the brakes are released or nearly released. The valve 19 for controlling the admission of air to and its release from the brake cylinder is actuated by a stem 17, 18 upstanding from the diaphragm 13.
