Patent DE-3149561-A1 (DE)
Title: Torque wrench
Inventor: HEINLEIN HANS
IPC: B25B23/142
Filed: 1981-12-15
Abstract: A torque wrench (1) for transmitting a presettable torque or clamping moment to a workpiece capable of being screwed, preferably having an outer square (2) for connection to exchangeable socket wrenches or the like, is proposed, in which according to the invention a shaft (5) provided, on the one hand, with an adjusting element (4) and, on the other hand, with a square (2) is rotatably arranged in bearings (6, 7) in a cylindrical sleeve (3) for transmission of the torque, a friction surface (8) and a second friction surface (9) cooperating with said friction surface (8) and firmly attached to the shaft (5) are provided at at least one end of the sleeve (3), and means for changing the axial distance between the two friction surfaces (8, 9) are in connection with the shaft (5). As a result, the torque to be transmitted is determined by the friction force between the friction surfaces (8, 9 and 13, 14). The setting of the friction force takes place by axial adjustment of the friction surface (8, 9 and 13, 14) relative to one another in a simple manner. For adjustment purposes and for setting the torque, openings (15, 16) which are axially parallel and are arranged on the periphery and into which shearing-off adjustment rods (17) can be inserted are provided in assigned discs (13, 14). The number of adjustment rods, which shear off upon turning the sleeve (3) relative to the shaft (5) as long as the shaft (5) is secured by a handle (22), is a measure, capable of calibration, for the torque to be transmitted. <IMAGE>

Patent DE-3215032-A1 (DE)
Title: Method for guiding smoke gas in a tunnel furnace and device for implementing the method
Inventor: SCHLICKER RUDOLF
IPC: F27B9/30
Filed: 1982-04-22
Abstract: In a tunnel furnace, by means of injection nozzles which are arranged in the side walls in the free region between goods for firing and the side walls between the firing zone and the furnace entrance and by means of which compressed air can be supplied, it is brought about that the waste gases, under the effect of pressure, do not flow along the furnace ceiling but in the lower region of the tunnel furnace in the direction of the furnace entrance. In the region between firing zone and furnace exit, injection nozzles can also be arranged, the direction of action of which is opposite in relation to the direction of action of the injection nozzle between furnace entrance and firing zone. The waste gas quantity is thus decreased by reducing infiltrated air in relation to conventional tunnel furnaces, lowering of the waste gas temperature below the condensation temperature is avoided, and  chipping and heating cracks on the goods for firing are prevented, without the furnace draught having to be increased. Preheaters can be throttled or stopped, and a considerable fuel saving is achieved.

Title: Process and apparatus for recovery of gaseous oxygen under elevated pressure
Inventor: SKOLAUDE WERNER DIPL ING
IPC: F25J3/04
Filed: 1982-05-03
Abstract: In a process for recovery of gaseous oxygen under elevated pressure by means of low temperature rectification of air in a pressure stage (8) and a low pressure stage (13), air is compressed, cleaned, at least partially cooled in a first heat exchange device (7) in heat exchange with separation product, and conducted into the pressure stage. A second gas stream (6) is compressed to a higher pressure, cooled in a second heat exchange device (11) in heat exchange with separation product, decompressed and likewise conducted into the pressure stage. Oxygen (14) is taken from the rectification in liquid form, pumped to the desired pressure, and evaporated and heated in heat exchange with the gas stream compressed to a higher pressure. The second gas stream (6) is split into two partial streams (21, 22), which are separately cooled at different pressures in the second heat exchange device. The partial stream (21) with the lower pressure is taken from the heat exchange device (11) at a higher temperature than the highly compressed partial stream (22), is decompressed while performing work, and is at least partially conducted into the rectification. <IMAGE>

Title: Antireflection screen for exterior rear-view mirrors in motor vehicles
Inventor: GEILHAUPT MANFRED DIPL PHYS DR
IPC: B60R1/08
Filed: 1982-08-31
Abstract: In the dark, the harsh light of the headlights of following vehicles has an extremely disturbing effect because the light which is deflected into the interior of a vehicle by interior and exterior rear-view mirrors has a highly dazzling effect. It proves extremely useful if the dazzling effect of the incident light from the headlights can be eliminated by means of a tilting device on the interior rear-view mirror. This is not possible for the exterior rear-view mirror. An anti-reflection screen for the exterior rear-view mirror is suitable as an alternative anti-dazzle device. This screen is composed of a plurality of plastic laminas of the same type. These laminas can be extended and pushed together like a fan so that the dazzling effect of harsh light can be eliminated as required. The anti-reflection screen is provided with suckers so that it can be easily mounted. <IMAGE>

Title: Electrical switchgear cabinet
Inventor: GRASS HERMANN
IPC: H02B1/32
Filed: 1982-11-22
Abstract: An electrical switchgear cabinet for low-voltage installations is formed from a frame which is formed from profiled strips 10, 12; there are push-in drawers, which are bounded at the bottom by means of a base metal sheet (14, 16), in the switchgear cabinet. The base metal sheets are held by means of retaining elements (30) which are firmly screwed to the profiles (12). In order to achieve optimum guidance of the base metal sheets, each retaining element (30) is constructed approximately in a box shape and, on its top, has a web (44) which engages in a slot (70, 72) on the base metal sheet and thus ensures lateral guidance of the base metal sheet. In order that the base metal sheet cannot be raised upwards, it is surrounded on its front edge in a U-shape in such a manner that the one free limb (16'') engages around the retaining element from underneath. In order that the base metal sheet cannot be pulled out from the front, a flap (76) is provided which acts as a stop against the rear surface of the retaining element. <IMAGE>

Title: Plane iron, in particular profiled iron
Inventor: BERGLER OTTO
IPC: B27G13/04
Filed: 1983-05-24
Abstract: A plane iron is described, designed in particular as a profiled iron which is pressed onto a plane head symmetrically to a further plane iron and to the axis of rotation with the aid of a clamping flap and with fastening screws. On the side, remote from the iron cutting edge, of the openings for the passage of the fastening screws, provision is made for a groove which runs parallel to the plane in which the median axes of the openings lie and into which collars of the adjusting screws engage. As a result of this arrangement, it is possible to actuate the adjusting screws in a simple way from the side of the plane head remote from the iron cutting edges. The iron itself exhibits no weakness, due to grooves or other openings, in the region of the cutting edge and in the adjoining clamping region.
