Abstract: A cooling apparatus for cooling a heat-generating member includes a cooling flow path, a condenser, a coolant-returning flow path, a first check valve and a second check valve. The cooling flow path is thermally connected to the heat-generating member. The condenser is connected to a downstream portion of the cooling flow path and condenses a coolant contained in the cooling apparatus after the coolant is evaporated in the cooling flow path. The coolant-returning flow path returns the coolant condensed by the condenser to an upstream portion of the cooling flow path. The first check valve is disposed between the coolant-returning flow path and prevents the coolant from flowing in a reverse direction from the cooling flow path to the first coolant-returning flow path. The second check valve is disposed between the condenser and the coolant-returning flow path and prevents the coolant from flowing in a reverse direction from the first coolant-returning flow path to the condenser.

Abstract: A modular custard freezing machine housed in a cabinet that consists of interior support members whereto panels are releasably connected and supports components of the machine including: a deep pan in the cabinet top for receiving a custard mix poured therein to pass that mix, on demand, through a valve that directs the mix flow into a freezing barrel of a custard freezing chamber; the custard freezing chamber includes the freezing barrel, a coolant gas chamber therearound with a layer of insulation formed around that freon or other coolant gas chamber and contained within a housing that is mounted to a platform; the platform further includes mounted thereto, aligned bearing mounts whereto aligned bearings are secured to receive a shaft journaled therethrough, the shaft further including a pulley thereon that is turned through a belt by an electric motor, and connected to a collar whereto a shaft of a paddle assembly is splined; which paddle assembly is arranged for turning in the freezing barrel, congealing

Abstract: A wheeled land vehicle in which at least one free-running ground-engaging wheel has power take-off means connected thereto for providing power in or on the said vehicle, such power take-off means including an input shaft coaxial with and drivingly connected to said ground-engaging wheel and extending inwardly therefrom through a non-rotary hollow axle shaft, and power take-off mechanism drivingly connected to the said input shaft and mounted in cantilever fashion on an inboard termination of said axle shaft.
