Abstract: A mount base for use with an absorption refrigerator according to the present invention comprises a plurality of pairs of legs spaced by a distance from each other and mounted to a lower side of the cabinet such as the low-temperature and/or high-temperature cabinet, and a plurality of link plates securely joined to the legs thus forming an inner space defined by four sides beneath the cabinet, and will thus be increased in the physical strength for supporting the low-temperature and/or high-temperature cabinet. When the low-temperature and/or high-temperature cabinet is shaken by e.g. earthquake, it remains supported securely by the combination of the legs and the link plates, more specifically, the legs reinforced with the link plates and thus is prevented from fracture or injury.

Abstract: An absorption type refrigerator capable of returning an abnormally high temperature of heating water or an abnormally low temperature of cooling water to a normal temperature without stopping or switching the operation of the refrigerator is structured such that return heating water 46b is heated with refrigerant vapor 7a in a heater 41 and is provided to a heating load 310. When the temperature of the heating water 46a becomes abnormally high because the heating load 310 is small or zero, the switch valve V1 is opened to cool part of heating water 46a with part of cooling water 32 for heat radiation so as to reduce the temperature of the heating water 46a to a normal temperature. The heat of the heating water 46a may also be radiated by an air-cooled heat exchanger provided along the passages 44 and 45 of the heating water 46a.

Abstract: It is an objective of the present invention to improve the response performance of absorption refrigeration machine to changes in air-conditioning load by reducing irregularity in solution concentration. A spreader 34 is provided with openings 34a having a constant diameter, and these openings are positioned or aligned in such a manner that the concentration of the openings 34a is rare on one side of the spreader but dense on the other side. The side having the rare concentration of the openings 34a is placed to the lateral wall 1a of a vessel 1 in which a solution outlet 16 is provided. The side having the dense concentration is placed to the other lateral wall 1b of the vessel 1. The spreader 34 is placed at the position where it is slightly away from the solution outlet 16 toward a front wall 1c in a vapor portion of an evaporation-separative region 19, with the bottom plate of the spreader being horizontal.

Abstract: A cushion or trackbed material for use in a riding-ground is obtained by coating sand with a carboxyl-containing olefin polymer and an oxygen-containing wax.

Abstract: A polyethylene composition which has a wide molecular weight distribution and excellent balance among melt elasticity, flow characteristics and mechanical properties, and which is suitable for use in producing large-scaled hollow plastics articles. The composition comprises a higher molecular weight ethylene polymer or copolymer and a lower molecular weight ethylene polymer or copolymer which is specified in view of the content of o-dichlorobenzene and the ratio of the area under the elution temperature-eluate volume curve between 25.degree.to 90.degree. C. to the area under said curve of 90.degree. C. and above in temperature rising elution fractionation.
