    摘要: The gel range of acid-acting delayed-action gelling agents, such as sodium silicofluoride, in latex spread foam compounds which are to be gelled by subjecting them to a preliminary heat treatment prior to drying is substantially broadened by including a water-soluble ammonium or amine sulfamate in the compound. At least 0.5 parts by weight of the sulfamate should be used per 100 parts by weight of dry solids in the starting uncompounded latex. It can be added to the latex at any time before or during the compounding step and it is preferably added with 0.5-1 part of a soap per part of sulfamate and also with sufficient ammonium hydroxide or other ammonia donor compound to maintain the pH of the compounded latex composition at 9.5 or higher.

    摘要: Systems for powering vehicles using compressed air and vehicles involving such systems are provided. In this regard, a representative system includes: a power source configured to power an air compression system, the air compression system comprising at least one air compressing piston; a compressed air storage system, comprising at least two storage tanks configured to store compressed air from the air compression system; a valve configured to control release of air from the compressed air storage system into a rotor system; the rotor system comprising a first air jet configured to direct the released air into a plurality of paddles located about a circumference of at least one rotor, thereby turning the at least one rotor.
