Title: Door equipment element for a door or the like of a motor vehicle
Inventor: NAU J F YVES
IPC: E05B65/20
Filed: 1989-03-18
Abstract: It is known that doors of motor vehicles are equipped with a multiplicity of separate elements. Extensive equipping means a high outlay on manufacture and so production has gone over to combining individual elements to form subassemblies. A door equipment element (1) for a door (2) or the like of a motor vehicle is thus known, the door (2) having a door lock (7) and the door equipment element (1) containing the door lock (7). The manufacturing outlay for the production of a door (2) can then be reduced if lighting elements (8, 9, 11, 12) and/or functional elements are integrated into the door equipment element (1). <IMAGE>

Title: Process for applying bituminous self-adhesive tape to wood-fibreboards, and application thereof
IPC: C09J7/38
Filed: 1989-03-25
Abstract: In order to seal the joints between wood-fibreboards (fibreboards, building fibreboard, hardboard) an adhesive tape having a bituminous self-adhesive layer is used. Before applying the tape this adhesive layer is wetted with a solvent. This renders the adhesive tape adhesive even on cold and moist wood-fibreboards. Applications result when the wood-fibreboards are laid as an under-roofing element or as a windbreak on outer walls.

IPC: F16J15/36
Filed: 1989-10-18
Abstract: The present invention provides a mechanical shaft-end seal assembly to seal a shaft (1) against a housing (2). The assembly comprises: a support ring (3) secured to the shaft (1) and forming a hermetically tight joint therewith; an annular thrust member (7) installed between the shaft (1) and the housing (2), with a clearance relative to these, displaced along the shaft (1) relative to the support ring (3), held by means of an elastic member (10) to the support ring (3) and forming a friction pair therewith; means (13, 14) adapted for locking the annular thrust member (7) to prevent rotation relative to the housing (2); and a sealing ring (20) installed between the housing (2) and the annular thrust member (7). The sealing ring (20) is made of flexible elastic material and has, in radial section, an U-shaped form consisting of two interconnected branches, one branch being attached to the housing (2), the other branch having its tail part attached to the annular thrust member (7). Thus the sealing ring (20) can accommodate movement of the thrust member (7) relative to the housing 2. <IMAGE>
Patent DE-3936962-A1 (DE)
Inventor: EVERS WALTER
IPC: E03C1/10
Filed: 1989-11-07
Abstract: Backflow preventers especially suitable for fitting in drinking water pipes have a through-flow housing (1) containing an inlet and an outlet pipe (2 and 3) with a spring-loaded inlet valve (4) inside it and a spring-loaded outlet valve (8) and a central chamber (13) arranged between the two valves (4, 8). When the differential pressure between said central chamber and the inlet pipe (2) dropes below a set minimum, said chamber can be caused to communicate with the outside atmosphere via a discharge valve which then opens, the body (28) of which is connected for this purpose to control components (18, 18') actuatable on one side by the inlet pipe pressure and on the other by the pressure in the central chamber, and can be raised from its outlet valve seat (30), freeing both a water outlet aperture and a ventilating aperture leading to the central chamber (13). In order to obtain an even simpler design for this outlet valve and improved water drainage and ventilation facilities for the central chamber (13), the water outlet aperture of the outlet valve and the ventilation aperture are combined into a single connecting aperture (14, 32) with a relatively large cross-section between the central chamber (13) and the outer atmosphere which can be steplessly opened more widely by the valve body (28) depending on the extent to which it is open.

The plaster forming the layer (20) has a high thermal conductivity and its surface is a good reflector of light. The plasterboard panels a are acoustically absorbent. USE - Suspended cielings in buildings.
Patent DE-4010733-A1 (DE)
Inventor: CRAWFORD JOHN J
IPC: G06F12/14
Filed: 1990-04-03
Abstract: In a microprocessor, means for detecting misaligned data references is selectable such that when it is enabled and reference is made to a misaligned data object, a fault is produced which interrupts the currently executing program. The detecting means comprises two mode bits stored within the microprocessor. The first mode bit provides control of the fault at the least privileged level of execution (i.e., the applications level) while the second mode bit provides control of the fault at the most privileged level (i.e., the operating system level). Both mode bits must be set to "1" in order for the detecting means to be enabled. The use of two separate mode bits for optionally enabling alignment checking provides optimum programming flexibility. <IMAGE>

Patent DE-4017367-A1 (DE)
Title: Cleaning insides of pipes - involves rotary nozzle assembly coupled to separate rotary drive device
Inventor: MUNDING HARALD
IPC: B08B9/053
Filed: 1990-05-30
Abstract: The appts. for cleaning the inside face of pipes has at least one concentrically arranged rotary nozzle assembly with radially aligned nozzles.  A rotary drive unit (10,12,13,14) is coupled to the rotary nozzle assembly and its speed is controllable. THe relative rotational speed of the nozzles (7a,7b) relative to the inside face of the pipe (1) is independent of the pressure jet emerging from the nozzles.  The rotary nozzle assembly can be fixed on a rigid pipe line (10) which is mounted rotatable in a guide sleeve  (11) on which a motor (14) is fixed. USE/ADVANTAGE - The pressure jet is no longer used to rotate nozzle assembly but indenpendently controlled speed produces less damage to inside surface.
