Patent DE-3220248-A1 (DE)
Title: Space heating unit for solar systems
Inventor: SCHAEFER ERWIN DIPL PHYS
IPC: F24D11/02
Filed: 1982-05-28
Abstract: The invention is distinguished in that, besides the heating body acted upon by the solar system, it contains in the heating unit a second heating body for secondary heating, if the need arises, which is fed from another source (electric current, heat pump, etc.). It is thus possible to use the heat in the solar circuit or solar reservoir down to near room temperature. Secondary heating does not occur, in the currently conventional way in the solar reservoir with considerable preparation losses and a drastic deterioration the efficiency of the plant, but only if the need arises directly in the heating unit by means of the second heating body. This means:     1. Improvement of the efficiency of the solar plant,   2. Better use of the solar reservoir,   3. No preparation losses. s

Patent DE-3300662-A1 (DE)
Title: Level control device for vehicles
Inventor: BARTHOLOMAEUS REINER
IPC: B60G17/033
Filed: 1983-01-11
Abstract: The invention relates to a level control for a vehicle in which various heights of the body are predetermined by setting reference value signals. The feedback occurs by way of inductive travel sensors. The reference value and actual value signals serve to trigger 2/2-way solenoid valves, by way of which the pressure chambers of assigned vibration dampers can be connected to a pressure medium source and/or to the tank. In the currentless state the valves are held in the closed position by springs. This ensures that even in the event of an electronics failure the position assumed by the body is maintained. In addition connections are made to the seat valves in such a way that the vibration dampers and the pressure medium source are protected against overload without additional valves having to be provided. <IMAGE>

Patent DE-3310251-A1 (DE)
Title: Concrete floor for a construction
Inventor: HOEHNE FRANK
IPC: E04B1/36
Filed: 1983-03-22
Abstract: The invention relates to a concrete floor having a supporting edge region (4) and a ... device for forming a clearance along a strip (10) at the upper outer end of the supporting edge region and a strip (11) at the lower inner end of the supporting edge region. In this arrangement, it is desired to avoid the possibility of a rigid bridging of the clearance or "air" strip in certain places. This is achieved by providing a groove (10, 11) along the upper outer strip and the lower inner strip, which groove is filled with a compressible material (12). Since the clearance strips are filled along their entire length with the compressible material, they are unable to accommodate any more rigid bridgings in certain places and nevertheless prevent, during the ..., the undesired pressure on the load-bearing wall or the upper load. <IMAGE>

Title: Process for energy saving in the control of the air temperature in buildings, and building for this purpose
Inventor: SCHMITZ JOHANNES DR ING
IPC: F24F5/00
Filed: 1983-10-07
Abstract: Methods of energy saving in the control of the air temperature in buildings have hitherto been confined to the insulation of the building against radiant heat loss and to the recovery of new heat from the environment by the use of heat pumps. This method can be improved on in that at least parts of the external walls have air flowing around or through them through corresponding air guide channels, this circulating air being supplemented by used air from the rooms of the building and the different channels of the building and, at least partially, fed to a heat pump which, for its part, either feeds air from which the heat has been removed back into the said circuit or discharges it to the exterior, in partial quantities in each case, the air discharged to the exterior being replaced again by fresh air sucked in by the reduced pressure within the building due to this discharge. For this purpose the building is to have corresponding air conducting channels and also a corresponding collecting channel on the suction side of a flow machine, a heat pump being provided in parallel with the flow machine and also being able to be connected via ducts to the ambient external air.
