Patent DE-3149052-A1 (DE)
Title: Broaching valve
Inventor: GEILHAUSEN PAUL
IPC: F16L41/04
Filed: 1981-12-11
Abstract: In a broaching valve, which is provided with a stop for limiting the closing movement of the main closing piece, the stop is fitted on the spindle-side end of the shaft which supports the main closing piece. The main closing piece is of very short construction so that, in the closed position, it projects only slightly into the cross-sectional region of the flow opening of the junction connecting piece. Furthermore, the main closing piece, which is provided with a coating of rubber-elastic material, is constructed cylindrically on its section which faces away from the spindle and interacts with the seat, this section having a slightly larger external diameter than the internal diameter of the associated region of the valve seat. In this way, pre-sealing and also a certain displacement of the rubber-elastic material into the main seating region are made possible, which contribute to a perfect sealing effect, which is intended to be achieved without the main closing piece being pressed into the seat under the influence of large forces.

Title: Clamping rail for fixing thin-walled skins to a loadbearing substructure
Inventor: MENGERINGHAUSEN MAX DIPL ING D
IPC: E04H15/64
Filed: 1983-03-25
Abstract: The clamping rail for fixing thin-walled skins to a loadbearing substructure, e.g. a skeleton structure, consists of a profiled enveloping strip 4 provided with a longitudinal slot 4a and of a profiled filling strip 5. One edge, formed into a hollow hem 1a, of the skin 1, 1', which extends outwards through the longitudinal slot 4a in the profiled enveloping strip 4, is clamped between these strips 4, 5. The clamping action occurs when tensile forces running perpendicularly to the axis of the clamping rail act on the skin. For further improvement of the clamping action of such clamping rails, on the one hand, and for perfect clamping of skins even with different thicknesses using one and the same clamping rail, on the other hand, at least the profiled filling strip 5 has a drop-like or wedge-shaped cross-section. When tensile stresses occur or are produced in the fixed skin, the profiled filling strip 5 together with the skin 1a enveloping it is pressed into the longitudinal slot 4a of the profiled enveloping strip 4, the clamping action being greater, the greater the tensile stress in the fixed skin. <IMAGE>

Title: Increase of efficiency of circulation-connected heat recovery systems for air-conditioning plants by incorporation of a heat pump with additional possibility of air cooling and exhaust heat utilisation
Inventor: HARTL JOHANN DIPL ING
IPC: F24F12/00
Filed: 1983-07-05
Abstract: In circulation-connected heat recovery systems, the efficiency of the recovery is relatively low in comparison with regenerative systems. The efficiency can be considerably increased by a suitable incorporation of a heat pump. The system can also be used for external air or supply air cooling, by bypassing the heat carrier medium flow direction by means of changeover valves. Furthermore, heat can be withdrawn from or fed into the system by the suitable incorporation of connections. A high performance index of the heat pump, and thus also a high economic efficiency, can be achieved.

Patent DE-3332768-A1 (DE)
Title: Rotary grip
IPC: G05G1/08
Filed: 1983-09-10
Abstract: A lock inserted into a door leaf or a fitting mounted in a window frame are provided with a square orifice, into which engages a square pin inserted into the handle of the rotary grip. The handle of the rotary grip is mounted rotatably in an assembly plate screwed together with the door leaf or the window frame. Since the lock or the fitting is likewise arranged firmly in a corresponding recess, production-related errors of alignment between the insertion orifice of the lock or fitting and the square pin to be inserted into the orifice occur. The handle neck of the rotary grip according to the invention is mounted in a bearing bush deflectable relative to the stationary assembly plate. During the assembly of the rotary grip, the bearing bush then adjusts itself automatically to the direction of the square pin predetermined by the insertion orifice. So that a deflection in the direction predetermined by the insertion orifice is possible, the bearing bush is enveloped by a ring made of elastic material, the outer shell of which is arranged firmly in a perforation of the assembly plate. <IMAGE>

Title: Automatic electrical generator system
Inventor: HILDEBRANDT LUTZ
IPC: H02K53/00
Filed: 1984-03-30
Abstract: The electric motor (1) draws its electrical energy (for example 25% mains current) as a first energy load before the current is emitted into the network distribution (4 + 5) (for example 75% of the quantity of electrical energy). This system of energy division for the electric motor load (1) in order to set the generator (2) in operation in order that the energy can be produced is related to automatic electrical generator system production. The proportions over 25% of the electric motor load before the distribution into the electrical network (75%) of the produced energy quantity are considered purely theoretically and do not correspond to the actual practice. <IMAGE>
