Abstract: A control for use with an expendable refrigeration system is disclosed which has particular use in refrigerated transport applications. The control is used to regulate the injection of refrigerant into the space to be refrigerated and provides an accurate means of precisely selecting a preferred ratio of "on" to "off" timing segments in each cycle and the number of complete cycles in a given time frame. In one embodiment of the invention, pneumatic pressures are used to power an oscillating device, the number of oscillations are counted to a selectable total. Attainment of the chosen total causes the counter to transmit a signal, which signal actuates the operator of a four-way valve. The switching of the valve provides the means to (a) open a liquid line valve to inject the refrigerant into the refrigerated space and (b) reset the counter, terminate the actuation signal and start the next cycle count.

Abstract: A frypan lid comprises an upper transparent plastic cover and a lower heat resistant plastic collar fixedly connected to the transparent cover and adapted to fit on a rim of the frying pan. The collar acts as a heat insulating body between the cover and the frying pan so as to prevent heat generated by the frying pan during use from adversely affecting the cover. The frypan lid prevents grease or the like from spattering out over the area immediately surrounding the pan, while at the same time enabling one to view the contents of the pan. Since both the cover and collar are made of plastics, the lid is also light-weight and practically non-breakable.
