Abstract: This disclosure relates to a laminate of several layers of rubber compounds. The laminate may be in sheet or strip form with various cross-sectional shapes. The layers in the laminate comprise rubber compounds, some of which contain agents which either assist or retard cure by irradiation so that the layers will have different physical characteristics during the manufacture of end products containing the laminate. The laminate may be cured by any known method, either irradiation or thermal, after its assembly into the final product.

Abstract: In a prepayment fluid feeder, a depressing member forces down a valve driving member through a coin located in a coin interposing space by an operation of a handle. When the driving member is depressed, a valve member is shifted to an open position, and a fluid such as tap water is supplied through a flow pipe. The driving member is locked by a locking mechanism in a position to which the member is depressed. A releasing mechanism acts on the locking mechanism and releases the locking of the driving member when the supply of a predetermined flow quantity is completed with a single coin, and the valve member is returned to the closed position, thereby stopping the supply of the fluid. The releasing mechanism comprises a setting wheel with notches formed on the outer periphery thereof and balls placed in the notches.

Abstract: A liquid quality-evaluating apparatus for liquids whose boiling point or vapor lock point vary by deterioration includes a heating vessel made of heat conductive and electrically conductive material and adapted to hold a brake fluid whose quality is to be determined. The heating vessel has an opening which is closed by an electrically and heat insulating removable cover and the wall of the heating vessel near the bottom is fitted with a nozzle acting as a siphon. The cover carries a hollow cylindrical electrode so disposed as to slightly dip into a brake fluid received in the vessel. A heat-responsive resistance element for detecting the temperature of the brake fluid is received in the hollow cylindrical electrode. A heater is provided below the heating vessel to heat the brake fluid received therein. A current cutoff-detecting circuit is electrically connected between the heating vessel and the hollow cylindrical electrode. A liquid temperature-indicating circuit for displaying the temperature of the brake fluid is connected to the heat-responsive resistance element. A liquid temperature-indicating pointer used with the liquid temperature-indicating circuit is locked by an output signal from the current cutoff-detecting circuit which is actuated when the level of the brake fluid falls when the brake fluid boils.

Abstract: A method of forming a mold for use in casting is disclosed. The method includes as a first step forming a positive pattern having a surface the shape of a part to be cast. Next a negative partial pattern is formed having a casting surface complimentary to a selected portion of the surface of the positive pattern and also having a reference surface in a fixed spatial relationship with the casting surface. The casting surface of the negative partial pattern is placed in complimentary engagement with the selected portion of the surface of the positive pattern to form a pattern assembly. A first mold section having a surface complimentary to the reference surface and to the surface of the part is formed by dipping the assembly formed in the preceding step in a ceramic material. A second mold section of ceramic material is formed having a casting surface identical to the casting surface of the negative wax partial pattern and a reference surface identical to the negative partial pattern reference surface, the casting and reference surfaces bearing the same spatial relationship to each other as the identical surfaces of the wax partial pattern bear to each other. Finally, a core is attached to one of the mold sections and a complete mold is formed by placing the reference surface of the second mold section in abutting engagement with the complimentary surface of the first mold section.

Abstract: The slide valve includes an outer (1) and an inner (4) valve housing. End pieces (2, 3) and retaining end members (5, 6) keep the inner valve housing stationary within the outer valve housing and a fluid flow channel (24) of cylinder shell shape is formed between the outer and inner valve housings.

In addition to openings the retaining end members (5, 6) the path of flow through the slide valve is formed by the fluid flow channel (24) and the fluid flow openings (21, 22). The path of flow is blocked by the valve slide (7) which has end surfaces of unequal areas cutting off those fluid flow openings (21) of the inner valve housing (4) which are situated at the end of the valve slide having the larger area, in response to a fall of pressure of a predetermined magnitude arising across the slide valve. By means of friction members (15, 16) arranged at the valve slide and having frictional engagement with the inner valve housing (4) and setting members (10, 18, 19) arranged in the valve slide it is possible to set the pressure (= the fall of pressure across the valve) at which the valve closes fairly independently of the dimensions of the flow-restricting flow channels and openings (21, 22, 24) of the slide valve.
