Abstract:
In an electric motor with a spherical air gap, wherein the rotor is supported by a bearing permitting rotation and rocking about the center of curvature of this gap. Both the stator and the rotor have elements with concentric surfaces of revolution in relation to the axis of rotation and facing each other which so overlap each other that they prevent a separation between rotor and stator.
Abstract:
A temperature conditioning device for controlling temperature in a room where said device has a heat source wall, a heat sink wall, and a chamber between the walls adapted to be filled with a saturated vapor of a low boiling point heat carrier whereby the vapor of the condensate serves to transfer heat between the walls. A temperature responsive condensate control valve may be included to control flow of condensate of the heat carrier from one wall on which it may condense to the other wall on which it vaporizes such that the valve serves to regulate transfer of heat between the walls. A method of charging a temperature conditioning device with a low boiling point heat carrier which includes cooling the device, evacuating a chamber in the device, and then injecting in liquid form a low boiling point heat carrier into the chamber.
Abstract:
A freezing chest or freezing shelf comprising a compressor, heat exchangers and a heat storage arrangement with a heat storage material having a crystallization temperature above the temperature of the evaporator and below the maximum permissible temperature of the goods to be refrigerated. The heat storage material is arranged in containers formed from thin walled plastics, and the containers are disposed between the container of the goods to be refrigerated and the insulating layer, and are in contact with the wall of the former over approximately half the total surface. Further, the containers of the heat storage material have recesses for the evaporator tubes which are equally in contact with the wall of the container of the goods.
Abstract:
A coolant pump for liquid cooled engines where the pump casing has a chamber, a rotatable drive shaft in the pump casing, a first pole ring on the drive shaft and a second pole ring rotatably mounted in the pump chamber which has impeller blades thereon and means for hermatically sealing the pump chamber from the drive shaft and first pole ring. Means may also be included for varying the slippage between the first and second pole rings in order to vary pump output.
Abstract:
Variable heat insulation building panel having an outwardly facing wall, an inwardly facing wall, a chamber between the walls and a means for creating eddy currents in the chamber to promote transfer of heat between the two walls in order to reduce insulation effect of the panel.
Abstract:
A device for cooling a semiconductor component comprising a chamber enclosing a non-metallic crystal forming material which experiences a phase change at a temperature which corresponds to the desired operating temperature of the semiconductor component and wherein the material is in thermal communication with the semiconductor component.
Abstract:
An inductive driven centrifugal pump having an impeller mounted in a bearing for limited universal movement and including a seal between the impeller and a portion of the pump casing and fluid passage means connecting opposite sides of the impeller whereby fluid pressure acting on opposite sides of the impeller is equalized.
Abstract:
A refrigeration machine circuit, comprising a storage mass which gives off its heat of crystallisation at approximately 4*C where the mass is in heat conducting communication with an evaporator of the machine and where the mass has water from a cold water circuit playing on it.
Abstract:
Spherical bearing construction having two cups engaging a ball wherein at least one of the cups has an effective frictional area which is asymmetrical with reference to the axis of rotation of the cup with respect to the ball.
Abstract:
Centrifugal pump having a pole ring for producing a rotating magnetic field which drives a second rotatable pole ring which is connected to impeller blading where the second pole ring is axially supported with respect to the first pole ring by a fluid bearing film.
