Title: Plane grate consisting of individual grate bars
Inventor: REINDL SIEGFRIED
IPC: F23H1/00
Filed: 1981-03-11
Abstract: The plane grate according to the invention is characterised in that a safe, trouble-free combustion of pressed wood wastes consisting of peeler shavings, tree bark or other fibrous wastes is possible. In order to achieve this, the individual grate bars (2 to 5) are designed in such a manner that they taper in the shape of a roof in cross-section. Below the respective roofs (2a to 5a) lie corresponding bases (2b to 5b) which are provided on both sides of the central plane (M-M) running through the roof ridge (DF) with in each case a groove-like recess (A1, A2). Thus, when two or more grate bars (2 to 5) are arranged next to one another, upwardly open air tubes (6 to 8) are created, these air tubes (6 to 8) preferably forming cylinders which broaden in a V-shape above the roof slopes (DS1, DS2). <IMAGE>

Title: Hardening device for workpieces with thin walls in order to obtain narrow tolerances
Inventor: HEESS KARL
IPC: C21D9/40
Filed: 1981-03-25
Abstract: The invention relates to a hardening device, which is composed of external (1) and/or internal segments (11). These segments are movable. These segments are driven by means of a planar thread (3) which combines with a ring gear (4) and a drive pinion (5) to form a single assembly. In this device, the segments are divided up into lower parts (6) which engage into the planar thread (3) and are guided in the body of the device, and upper parts (7) which are fastened to the lower parts (6) and have a shape which matches the workpieces. As the upper parts (7) can be easily replaced, they can be exchanged to match the different workpieces. The number of segments in the device can be selected to meet the requirements of the workpieces. <IMAGE>

Patent DE-3124106-A1 (DE)
Title: Sealing device for doors
Inventor: CRONENBERG DIETER-JULIUS
IPC: E06B7/02
Filed: 1981-06-19
Abstract: The bottom region of a door leaf can be fitted with a housing (1) in which actuating elements (8, 9) which are provided at both ends are mounted in such a way that they can be displaced as a function of the movement of the door leaf, said elements (8, 9) each being connected to a pressure piece (12, 14). In the central longitudinal region of the housing (1) lie two sliding parts (18, 19) which are held at a distance from one another by means of a compression spring (20). Between each sliding part (18, 19) and pressure piece (12, 14) is a curved flat-coil spring (24) which acts on a supporting profile (6), the latter holding a sealing profile (7). Upon closing of the door leaf (2), each flat-coil spring (24) is more greatly curved as a result of the pressure pieces (12, 14) being pushed together, the result being that the sealing profile (7) is moved downwards out of the housing (1) into the sealing position and pressed against the floor. The compression spring (20) has a greater force than the two flat-coil springs (24), as a result of which the sliding parts (18, 19) form an abutment for the flat-coil springs (24). For ventilation purposes, the sliding parts (18, 19) are drawn together against their compression spring (20) by means of a manually operated flexible, multiply deflected traction element (29), by means of which the flat-coil springs (24) become flatter and lift the sealing profile (7) upwards into the ventilation position. <IMAGE>

IPC: A63H19/24
Filed: 1981-08-08
Abstract: The circuit changes the travel direction of a model power unit when an overvoltage pulse is applied to the track. The core of the circuit is a latching relay which assumes one stable position as a result of a positively directed current pulse and assumes the other stable position as a result of a negatively directed current pulse. Said relay is alternately supplied in each case with control pulses of different current direction by an electronic control circuit when a voltage threshold whose position is determined by a zener diode is exceeded. <IMAGE>

Title: Roof element, namely reinforced-concrete prefabricated ceiling panel for flat-roofed buildings
Inventor: DENNERT HEINZ
IPC: E04B7/00
Filed: 1981-09-16
Abstract: The invention relates to a roof element, namely a reinforced-concrete prefabricated ceiling panel for flat-roofed buildings, having an essentially H-shaped cross-section such that the lower ends of the vertical H-leg rest on at least two building walls. In order that it is easy to mount, while having high static loadability and maintaining a constant degree of sealing, said roof element is provided, in the region of its vertical H-legs, with retaining devices for connecting, in particular bracing, ceiling panels lying one next to the other. Consequently, it is achieved that, even in the case of extreme thermal loadings, the ceiling panels, once they have been brought into their desired position, are mutually fixed such that gaping of the parting joint is not to be feared. Any expansion and contraction thrusts, in the horizontal direction, which may occur will not be able to affect the abutment region of the ceiling panels because the panels form a unit which is firmly braced together. <IMAGE>

Patent DE-3200460-A1 (DE)
Title: High-power radiation cooler
Inventor: BOETTCHER ALFRED PROF DR
IPC: F25B23/00
Filed: 1982-01-09
Abstract: In areas which have low nocturnal sky temperatures, air cooling is possible owing to the fact that a surface is insulated in the long wave infrared with respect to the ambient air, and air to be cooled is guided along the surface. In normal currents of air over the surface, a high air speed is required to achieve good heat transfer coefficients. According to the invention, this difficulty is avoided when the surface to be cooled is a side of a metallic nonwoven or fabric, and the air passes through the latter.
Patent DE-3206214-A1 (DE)
Title: Seating aids for patients for seating/reclining furniture elements
Inventor: KERSTHOLT FRITZ
IPC: A47C1/022
Filed: 1982-02-20
Abstract: The innovation relates to aids for seating/reclining furniture elements with the aid of which disabled persons can utilise the possible variation of the elements in furniture having movable elements, and can themselves actively change the position of their bodies as required. Bedpans may be built-in which follow all movements of the seat and are in the right position relative to the body for use at any time and in all positions of the body. In a piece of seating/reclining furniture with furniture elements whose angular position can be changed relative to one another and of which elements at least the seating element is mounted so as to be rotatable about an axis, at least one lever linkage acts upon at least one element, by means of which linkage at least one element can be turned or pivoted by the user in the clockwise or counter-clockwise direction from any positions of use, even counter to the load of the user. The lever linkage can engage directly on the seating element, but it can also be mounted on the basic frame and engage indirectly on the seat via an articulated intermediate element. It is furthermore possible to mount the linkage on the basic frame and to have it engage on the back rest. Finally, it may be actuated manually or via a motor.
