Abstract: In order to achieve an improvement in the efficiency of a refrigerating cycle and achieve quick and precise response to changes in the environment or the operating state while using carbon dioxide as a coolant, the refrigerating cycle according to the present invention is provided with a first expander and a second expander and further with a vapor-liquid separator provided between the first and second expanders. The components are arranged such that pressure of a vapor-phase coolant at high pressure, compressed by a compressor and cooled by a radiator, is reduced to an intermediate pressure level in a vapor-liquid two-phase range by the first expander. Then the coolant in a condition of a vapor-liquid mix is separated into a vapor-phase coolant by the vapor-liquid separator, so that only the liquid-phase coolant is expanded by the second expander, so that the vapor-phase coolant is taken into the intake side of the compressor while maintaining the intermediate pressure level.

Abstract: This invention relates to a method of resurfacing an ice surface to reduce friction between the ice and an object gliding on the ice surface. The steps comprise mixing an effective amount of lubricant with water, coating the ice surface with the mixture, and allowing the mixture to freeze to form a new ice surface. In particular, the lubricant is derived from siloxane. In the preferred embodiment, the lubricant is a composition derived from polydimethysiloxane and copolyolamine. In the preferred embodiment, the ratio of water mixed with the lubricant is 300:1. This invention also provides for the use of the composition as an agent to reduce friction between an ice surface and an object gliding on the ice surface. In particular, an effective amount of the composition is mixed with water prior to applying the mixture to a surface upon which the ice surface is to form.

Abstract: Apparatus to form and maintain a vent between the top and bottom surfaces of an ice core formed by ice extruders is disclosed. The vent is initially formed in one embodiment by a hollow member suspended within the freezing cell of the apparatus with one end of the hollow member forming a seal with a projection on the plunger that lifts the ice core upward during the extrusion of ice. After the vent is initially formed, the hollow member is removed and the plunger and projection begin a reciprocating motion causing the plunger to scrape ice from the walls below the ice core. The continuing motion of the plunger presses the ice chips against the bottom of the ice core and simultaneously causes the projection to seal the bottom opening of the vent, thus preventing the ice chips from closing the vent.
