Title: Heat pump installation with a variable temperature lift
Inventor: COST KARLFRIED
IPC: F25B49/02
Filed: 1988-07-01
Abstract: Technical problem of the invention. In present day heat pump installations, the maximum temperature lift is invariably bridged as the water is heated. It is the object of the invention to save drive energy for the heat pump by using the smallest required temperature lift in each case. Achievement of the technical object. The achievement is characterised by   a) a constant displacement of the compressor independently of the back pressure in the condenser by means of a suitable control device,   b) a constant liquid level in the evaporator by means of an appropriately controlled variable throttle (restrictor) between the condenser and evaporator, c) gradual heating of a relatively large quantity of water accompanied by a gradual rise in the temperature lift of the heat pump from zero to the maximum value, non-permanent operation of the heat pump with the maximum temperature lift.   Application area. Heating of service water from ambient temperature to a higher temperature.

Title: Apparatus for ring forming
Inventor: KADOTANI KAZUO
IPC: B21H1/06
Filed: 1988-07-21
Abstract: The invention relates to a ring-forming apparatus for cold-rolling workpieces into an annular configuration of desired shape. The workpieces comprise a bearing, in which an inner running surface, an outer running surface or a bearing shell are to be formed, or a housing or a bush. The apparatus comprises a forming roller, a mandrel and a supporting roller. The rate of rotation of the supporting roller is controlled in response to variations in the diameter of a workpiece and to match a rate of rotation of the forming roller. A pair of supporting rollers in rotary contact with circumferential surfaces of the workpiece under a constant pressure is locked in such a way that it follows the variations in the diameter of the workpiece synchronously. The apparatus can thus perform a forming operation on the workpieces with a high accuracy in terms of roundness.
