Abstract: A device for extracting water from a load of articles which have been washed uses fluid pressure to exert a force on the load. A system controls the fluid pressure such that only low pressure is applied to the load for a predetermined period of time at the beginning of the water extracting operation. Subsequently, the load is subjected to a high pressure exerted by the fluid.

Abstract: An improved air cooling type heat exchanger for a refrigerating apparatus accommodated in a container is disclosed, wherein the improvement consists in that the air cooling type heat exchanger is divided into a plurality of segments which are arranged in a stepped relation in the direction of main air flow in such a manner that they overlap with a certain distance kept between the adjacent ones. Thus, it is assured that the heat exchanger is designed and constructed in smaller dimensions and moreover it is operated at a high efficiency.

Abstract: A control device is used in a car-mounted air-conditioner of the air mixing type, in which a portion of the cold air, obtained by passing air through an evaporator, is heated by a heater via an air mixing damper. The control device includes a pulse generator, which is supplied with the outputs of a temperature setting device and of a room temperature sensor both of which are provided in a car in which the air-conditioner is mounted. The control device provides an amplified multi-phase pulse signal, based on deviations of the outputs, to an intermittent driving device responsive for rotating the air mixing damper.

Abstract: An air conditioner for vehicles in which the temperature of an evaporator is detected and an ON-OFF control of the compressor is achieved to maintain the evaporator temperature at a pre-set temperature. The air conditioner has means for detecting the temperature of air flowing into the evaporator, and means for varying the pre-set temperature in such a manner that the pre-set temperature is increased as the detected air temperature is decreased and is decreased as the detected air temperature is increased.

Abstract: An air conditioning apparatus for an automobile having a compartment comprises a cooling unit including an evaporator for cooling air, a heater for heating a portion of the cooled air, an air mixing damper for mixing the cooled air with the heated portion thereof and introducing the mixture into the compartment of the automobile, a control device for controlling the air mixing damper based on temperatures inside and outside of the compartment to keep the former at a constant temperature, a variable resistor connected operatively to the air mixing damper, and a temperature detector for detecting the temperature of the evaporator or the temperature of the cooled air supplied therefrom, the control device being responsive to an output of the variable resistor and the temperature detector for changing an operation command signal for the cooling unit.
