Abstract: There is disclosed laminates containing an adhesive blend, a rubbery adhesive cement as well as a method of using said cement, and products which can be prepared from the use of said cement.The rubbery adhesive cement comprises:(A) solvent, and(B) a vulcanizable rubbery polymer blend dissolved in said solvent wherein said blend is comprised of, based on 100 parts thereof:(a) 5 to 50 parts by weight of at least one rubbery conjugated diene polymer having 25% to 55% side chain unsaturation and having a Mooney viscosity of from 80 to 150 ML4 at 100.degree. C. as measured according to ASTM D1646, and correspondingly(b) 50 to 95 parts of at least one other rubbery polymer.

Abstract: A crop gathering head 10 including crop gathering belt 11, 12 of reinforced elastomeric material and its associated driving sprocket 30 and idler sheave 50 is described. The belt 11 or 12, sprocket 30 and sheave 50 system may be used to convey crops into a combine. The belt 11 or 12 includes a plurality of cleats 20 of elastomeric material on its top surface 18 and a plurality of equally spaced driving lugs 24 of elastomeric material on its bottom surface 19. The sprocket 30 has first and second sides 31, 32 respectively and comprises a plurality of equally spaced apart radially projecting teeth 33 separated by first and second cavities 34, 34' respectively. The first cavities 34 are open only to the first side 31 of the sprocket 30. The second cavities 34' are open only to the second side 32 of the sprocket 30.

Abstract: This invention is a fluid actuator of the rolling lobe form in which a closed toroidal flexible membrane forms concentric rolling lobes on the inside and outside surfaces of an annular piston which moves axially into the membrane. The fluid actuator can be used in brake and clutch assemblies where the actuator is connected to a high pressure fluid source and serves to activate the brake or clutch assembly, a shaft or axle can pass through the center of the toroid.

Abstract: A chopped textile reinforced shock absorber is made by chopping unvulcanized elastomer coated texile into lengths of about 0.25 of an inch (0.63 cm) to about 3.0 inches (7.62 cm) and preferably 1 to 5 cm and shaping the chopped unvulcanized elastomer coated textile into a thickness, width and length to function as a shock absorber when cured.

Abstract: There is disclosed the reaction product of an N-(substituted oxymethyl)melamine and a 2-mercaptoarylthiazole and its use as an adhesion promoter to improve rubber to metal wire adhesion.

Abstract: There is disclosed, in a microsuspension polymerization process for producing homopolymers and copolymers of vinyl chloride, having a dispersion step and a seed polymerization step, the improvement wherein butylated hydroxyanisole (BHA) is added to the dispersion step and, wherein, when necessary to control temperature, additional BHA is added to the seed polymerization step. There is also disclosed a homopolymer or copolymer of vinyl chloride produced by the improved process.

Abstract: A fire extinguishing apparatus for dispensing a dry chemical agent from a container by using a suitable supply of compressed gas such as carbon dioxide. The compressed gas is used to fluidize the chemical agent and carry the agent to a hand manipulated nozzle which is aimed at the fire. The extinguishing apparatus is actuated by removing a safety pin from the actuating lever, depressing the lever depresses a plunger valve that opens a passage from the container to the nozzle outlet and simultaneously transfers a linear motion to a tubular spool through a connecting lever. The tubular spool punctures a seal on a compressed gas cartridge releasing the gas into the container aerating the dry chemical and transporting it through the open plunger valve and out the nozzle.

Abstract: Power transmission belts have a cushion stock which improves the durability of the belts. The cushion stock contains a melamine and a silane and preferably cotton reinforcement and silica. 2-thiazolidinethiones can be used as accelerators in the cushion stocks.
