Title: Method of incorporating multifilament strands of carbon fibers into cement to produce reinforced structures having improved flexural strengths
IPC: C04B20/10
Filed: 1978-12-28
Abstract: A reinforced structure having improved flexural strength comprises a cementitious structure reinforced with multifilament strands of carbon fibers which have been impregnated with a liquid hydrophobic resin system prior to being incorporated into the cementitious matrix, which hydrophobic resin system has been cured simultaneously with the cementitious matrix and which serves to bond the fibers to each other and to the cement particles. The structure may be made by filling a mould with a cementitious mix, impregnating a continuous strand of carbon fiber with a liquid hydrophobic resin system and stringing the strand back and forth along a length of the mould on the surface of the cement, adding a second layer of the cementitious mix to the first layer and simultaneously curing the hydrophobic resin and cementitious mix. <IMAGE>

Title: Heat pump or refrigeration circuits
IPC: F24D19/10
Filed: 1980-06-26
Abstract: The evaporator (6) of a heat pump or refrigeration circuit is defrosted by use of a switching device 7. The refrigerant by-passes the condenser (4) and the choke valve (5) so that the refrigerant from the compressor (1) flows directly to the evaporator (6) and heats and defrosts the evaporator. Prior to this the refrigerant gas is preferably heat- exchanged with water of e.g. a water heater (3), which water suitably has been heated by the heat pump compressor (1) during its normal duty between defrostings. A small amount (9) of heat exchanged refrigerant gas preferably flows during the defrosting operation to the inlet of the compressor (1) in order to gasify in that inlet liquefied refrigerant, which may be present in the cooled refrigerant gas flowing from the evaporator (6). <IMAGE>
