Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a method and an apparatus for producing electrical power and for the simultaneous heating of fluid by means of a magnetohydrohynamic (MHD) generator.      The method includes heating a mixture of liquid metal and a propelling liquid to provide a two-phase liquid metal-vapor flow, directing the two-phase liquid metal-vapor through a MHD-generator to generate electricity, condensing the vapor phase from the two-phase liquid metal-vapor to form liquid metal carrying propelling liquid droplets and recycling the metal and propelling liquid droplets to be reheated.  The apparatus includes a closed duct system containing a mixture of liquid metal and a propelling liquid, a heater for heating the mixture in the closed system, a MHD-generator, located along the flow path of a two-phase liquid metal-vapor flow formed by the heated mixture, a condenser for condensing the two-phase flow to form a single-phase flow of metal liquid containing propelling liquid droplets and a pump to propel the single-phase flow to be reheated by the heating means.

Abstract: A 524 (R) Abstract of the Invention Triglyceride oils, which contain besides fatty acids having two double bonds, fatty acids having more than two double bonds, are hydrogenated using palladium, platinum, rhodium and/or iridium as a catalyst, the catalyst being treated with dry ammonia. The hydro-genation is carried out at a temperature of at least 100°C. The hydrogenation progresses in a particularly selective manner. On using, for instance, soyabean oil, which contains about 55% of linoleic acid and 7% of linolenic acid, the amount of linolenic acid can be reduced to 2%, whereby more than 45% of linoleic acid is retained in the hydrogenated product. In case the catalyst is not  treated, said amount is only about 35%.

Abstract: Abstract The air-to-air split system or packaged cooling system, including the heat pump system in the cooling mode, is used to cool buildings by rejecting the heat to the outside air.  The outdoor coil of the system acts as a condensor and rejects the heat, and the indoor coil acts as evaporator and extracts the heat from the air handling system for the building. This invention relates to the use of the described cooling system, or heat pump system in the cooling mode, in combination with the building exhaust system to reduce the overall energy consumption, when the outdoor air temperature is higher than the indoor exhaust air temperature, the resulting lower temperature of the mixed outdoor air and indoor exhaust air passing through the outdoor heat exchanger will improve the performance of the air cooling system, or heat pump system in the cooling mode, with a saving in energy.       The essential part of this invention is the  air diffuser with adjustable louvre, which is mounted on the exhaust fan and ties the two conventional systems together to form an energy saving system.

Abstract: ABSTRACT OF THE DISCLOSURE     Signal processing by means of a system com-prising  an  elastic  wave  device,  invariant  with the temperature.   The input  signal Se  is written  into a memory at the timing of a fixed clock he and read at the timing of a clock HL supplied by a slaved gene-rator, which also supplies the signals particularly for modulation to an  interface  circuit.   The  signal  is applied to an elastic wave device which supplies a pro-cessed signal S3 applied to a second interface circuit and to a second memory.   The  slaved  generator  also supplies  the  demodulation  signals  to  the  second interface circuit and the writing clock signals HE of the second memory, which  is read at  the  fixed clock timing hL.   The  slaved  generator  comprises  a  basic driver  formed  by  a  surface  elastic  wave  oscillator constructed with the  same  substrate  as  that  of  the elastic wave processing device.

Abstract: COMPACTION APPARATUS FOR USE WITH LAWN GROOMING EQUIPMENT             ABSTRACT OF THE DISCLOSURE       A compaction apparatus for use with lawn grooming equip-ment such as a lawn mower, leaf blower and the like, including a compactor housing having an inlet opening at one end to receive the refuse material picked up from the lawn and a screw conveyor rotatably mounted within the housing to transport and compact the received material as it is advanced through the conveyor housing.         Perforations in the housing provide outlets for evacuating from the housing, air and moisture separated from the compressed material as it is initially compacted in the housing.  A flexible tubular collector casing or hose is extensibly connected to the outlet end of the compactor housing, into which the initially compacted material is continuously advanced.  The cuttings and other refuse material are further compacted against the interior wall of the casing by the force of the continuously advancing material and form a plug in the end of the hose-like casing, causing it to extend from the outlet end of the compactor hous-ing like a sausage.  This sausage of compacted refuse material crawls in serpentine fashion along a guided path on the top of the main body of the grooming equipment.  When the casing, filled up with backed-up refuse material, has been extended or unfolded, the resultant sausage is severed from the compactor housing and may be dropped on the lawn for subsequent removal to composting dump or other collection site.       The screw conveyor may be provided with a bore for trans-porting a composting fluid from the inlet end of the conveyor to be discharged into the housing towards its outlet end.
