摘要： A foam generating apparatus is disclosed which generates foam from a foamable liquid by pumping the liquid by means of a high pressure pump from a storage tank to a combining device in which the liquid is combined with compressed air. The apparatus is capable of both operation and storage under extremely cold ambient conditions without the components of the apparatus becoming frozen. When the apparatus is not generating the product foam, a foamable liquid is recirculated throughout the apparatus to prevent the components of the apparatus from becoming frozen. The recirculation system is especially useful in preventing the high pressure pump from becoming frozen during storage in cold environments, while also reducing the amount of wear on the pump.
摘要翻译：公开了一种泡沫发生设备，其通过将高压泵从储罐泵送到液体与压缩空气结合的组合装置中，从可发泡液体产生泡沫。该装置能够在极冷的环境条件下操作和存储，而不会使装置的部件冻结。当设备不产生产品泡沫时，可发泡的液体在整个设备中再循环，以防止设备的部件冻结。再循环系统特别适用于防止高压泵在寒冷环境中储存期间冻结，同时也减少了泵上的磨损量。

摘要： In an apparatus for laying down a blanket of foam on a waste disposal landfill or the like, an enlongate manifold carried across the rear end of a vehicle delivers foam to nozzle assemblies which are spaced apart along the length of the manifold. Each nozzle assembly includes a holder in the form of a block with a first bore communicating with the manifold and bifurcating into second and third bores which communicate with nozzles having fan-shaped flat spray patterns. The axes of the bores generally define an inverted Y-configuration with the nozzle of the second bore arranged to spray the foam downwardly to one side and within a plane angled forwardly from a transverse vertical plane with respect to the direction of forward movement of the vehicle, and with the nozzle of the third bore arranged to spray the foam downwardly to the opposite side and within a plane angled rearwardly from the transverse vertical plane.
