Title: Electrical tubular heater
Inventor: SCHAD WALTER ING GRAD
IPC: H05B3/48
Filed: 1987-01-20
Abstract: An electrical tubular heater is disclosed. It is known for an electrical tubular heater to be provided with a closure plug (sealing plug) (1) which has an inner annular wall (2) which surrounds a central connecting bolt (3), rests by means of an outer annular wall (4) on the inner wall of the outer tube (5), has an intermediate space (interspace) (6) which extends between the annular walls (2, 4) and rests by means of a web (7), which merges in both annular walls (2, 4), on an insulating compound (8) for a heating resistor (9) which is arranged centrally in the outer tube (5). It is intended to prevent the closure plug (1) shifting from its seating like a piston in the event of internal overpressure in the insulating compound (8). In order to prevent such displacement, at least one through cut-out (10) is provided in the web (7), which through cut-out (10) enables pressure equalisation between the space in which pressure is produced and the environment of the tubular heater. <IMAGE>

Title: Control valve
Inventor: SCHAEFER HEINRICH DIPL ING
IPC: F16K17/10
Filed: 1987-03-20
Abstract: The invention relates to a control valve for a safety valve assigned to a pipe conduit supplied with a medium. Arranged on the valve housing (8) of the control valve are three connecting branches (1 to 3). The first connecting branch (1) is connected to the pipe conduit, the second (2) to the control space of the safety valve and the third (3) to a blow-off line. Two valve plates (6 and 7) are arranged in the valve housing (8) in a manner which allows them to be displaced counter to spring force. The first valve plate (6) is subjected via the first connecting branch (1) to the medium in the pipe conduit. The second valve plate (7) is part of a valve between the second and the third connecting branch (2 and 3). It is envisaged that the two valve plates (6 and 7) should be connected rigidly to one another by a part of a valve spindle (4) and that they should be displaceable counter to the force of just one spring (5). The two valve plates (6 and 7) are assigned to valve seats (9 and 10), opening and closing in opposite directions. The first valve plate (6) is arranged as part of a valve between the first and the second connecting branch (1 and 2).   <IMAGE>

Patent DE-3801575-A1 (DE)
Title: Multiple hanger
Inventor: GRUNDMANN ERNST H
IPC: A47G25/06
Filed: 1988-01-21
Abstract: Multiple hanger for simple and space-saving accommodation for a plurality of clothing or washing items, the clothes-supporting device, a clothes rack for smooth parts or a supporting strip for clothes hangers, being rotatably mounted in order to obtain convenient hanging of the clothing items in the horizontal and space-saving accommodation in the vertical position. The mounting of the multiple hanger lies outside the area of rotation of the clothes-supporting device, in order to enable attachment also to walls, doors and radiators. In wardrobes, the torque which arises is compensated for by clamping on a clothes rail and supporting on the wardrobe wall. The clothes-supporting device is maintained in the desired position by a releasable catch, it being possible to insert it from both sides. The catch lever releases the clothes-supporting rail downwards if its load becomes excessive. A locking bar which engages on the mounting protects against theft when items are hung on a clothes rail. Two multiple hangers provided with oppositely inserted clothes racks can be used as laterally closed washing driers after fitting together the bearing rods of the clothes racks.

Title: Method for the analysis of production-dependent, circumferentially distributed non-uniformities of a vehicle tyre, and device for carrying out the method
Inventor: HAGL SIEGFRIED DIPL ING
IPC: G01M17/02
Filed: 1988-07-14
Abstract: With traditional methods it is only possible to make a statement about the uniformity of the tyre as a whole; it is not possible to make a statement about influences to which the non-uniformity of the tyre can be attributed. In the method, a predetermined non-uniformity is analysed by successively mounting a plurality of tyres on the measuring rim (10) in each case with the point (21) having the non-uniformities to be analysed in the same respective angular rotation position ( sigma ), storing the magnitudes of the non-uniformities of each tyre (1) measured around its circumference and adding them up. The method is suitable, inter alia, for the quality control of motor vehicle tyres. <IMAGE>
