Title: Device for hardening the surface of workpieces
Inventor: DIENER REINHOLD DIPL ING
IPC: C21D9/30
Filed: 1988-06-01
Abstract: A device for hardening the surface of workpieces with smooth envelope curves or trench tracks by electric induction with a small-surface inductor (17) in rotary operation comprises three axes or directions (3, 12, 16) coupled in control terms. The workpiece holder (4) is rotated via the first drive (6) about the horizontal axis (3). The small-surface inductor (17) is fixed in the workpiece holder (18) and is movable along the horizontal direction (12) by means of the second drive (9) and along the vertical direction (12) by means of the third drive (13). These drives (6, 9, 13) are activated by a control device (20) in such a way that the coupling distance between the small-surface inductor (17) and the inductor action line and the angle between the main inductor direction and the tangential plane passing through the inductor action line with the workpiece surface to be hardened are kept constant. This makes small series of workpieces (7) with a homogeneous hardening result possible at low production costs. <IMAGE>

Title: Boomerang with variable flight properties
Inventor: KALTENEGGER GERHARD
IPC: A63B65/08
Filed: 1988-06-11
Abstract: An apparatus for boomerangs, with which the flight properties of the latter can be varied at any time (especially lengthening/shortening of the flight path, increased wind stability), and non-workshop-dependent method of trimming. The variation of the flight properties is achieved by changing the lift conditions by means of "control surfaces" built into the arms of the boomerang (cf. reference 4, Fig. 1). Adjustment of the control surfaces downwards: more lift = earlier turn = narrower flight path. Adjustment of the control surfaces upwards: less lift = later/less turn = broader flight path, combined with turn in front of the thrower (compensation for relatively strong wind). To trim boomerangs, an additional layer is applied to the undersides of the arms at the profile end (= narrower flight path, see above 2.1.) and then ground away until the desired flight path diameter is achieved (cf. reference 4, Fig. 2). The possibility of varying the lift conditions at any time permits     - the study of their effects   - the adaptation of the flight properties - to the capabilities of the thrower (throwing power, turning speed)     - to the wind conditions   The new method for trimming simplifies the preparation of boomerangs for the respective intended use (especially competition boomerangs). <IMAGE>

Patent DE-3833735-A1 (DE)
Title: Device for restricting the penetration depth of a cutting tool
Inventor: ARNEGGER RICHARD
IPC: B23D61/02
Filed: 1988-10-04
Abstract: In the case of a tool in the form of a saw blade (10) for an oscillating movement back and forth, a cutout (13) is formed on the longitudinal symmetry line (16) in the basic tool body (11), which bears, at one end, a toothed border (12) which is wider than the latter. Bar-type stop bodies (14, 15), having slots (19) which extend, at the two ends, in the latter, are introduced into the essentially triangular cutout (13), having two triangle sides (17, 18) running mirror-invertedly with respect to the longitudinal symmetry line (16) and at the same angle with respect to said line, such that the slotted bar ends enclose the basic tool body (11) on the triangle sides (17, 18) of the cutout (13). The extent to which the respective stop body can be pushed, towards the point of the triangular cutout (13), onto the basic tool body (11) is dependent on the depth of the slots (19) which differs in the case of the two stop bodies (14, 15). The material thickness of said basic tool body is somewhat greater than the slot width of the stop bodies (14, 15), which consist of a plastic material, with the result that the latter are fixedly clamped. A specific penetration depth of the tool is fixed by each of the two stop bodies (14, 15). After removing the lower stop body (14), used for a first operating step, the second operating step can be carried out with restriction of the penetration depth by the second stop body (15). <IMAGE>

Patent DE-3844605-A1 (DE)
Title: Pallet container
IPC: B65D77/04
Filed: 1988-06-11
Abstract: Known pallet containers with an internal container made of plastic and an external casing of metal grid bars for transporting and storing liquid products of all types are prone to the disadvantage that the plastic material used to produce the internal container is not resistant to UV radiation, and the pallet containers are therefore unsuitable as reusable containers. The novel plastic internal container (2) for pallet containers (1) has a black colouring to protect the container and the contents therein from UV radiation. An inexpensive and efficient black colouring of the internal container (2) is achieved by the fact that soot is added to the plastic, preferably polyethylene, to produce the container. <IMAGE>

Patent DE-3912106-A1 (DE)
Title: Fuel injection device
Inventor: SCHER UWE DIPL ING
IPC: F02M59/46
Filed: 1989-04-13
Abstract: A device (1) for the direct injection of fuel into the combustion chamber of a diesel internal combustion engine is described, with a pump piston (4) driven to reciprocate by a drive, which piston generates an injection pressure in a pump working chamber (3). The fuel injection device (1) has a high pressure line system (6a, 6b, 7, 8a, 8b), connectable to the pump working chamber (3) by way of a relief valve (5) and leading to an injection nozzle containing a spring-loaded valve needle, and a spring-loaded pressure limiting device limiting the level of the injection pressure. In order to largely prevent power losses due to the shutting-off of fuel, it is proposed that the pressure limiting device comprise a piston device (18), adjustably held in a cylinder arrangement (21) and connected to the high pressure line system, which device, in the event of a predetermined injection pressure limit being exceeded, is deflected against the force of a spring (9), freeing a certain volume. <IMAGE>
Patent DE-3913973-A1 (DE)
Inventor: SCHMITZ FRIEDHELM
IPC: C21D9/50
Filed: 1989-04-27
Abstract: The present invention relates to a process for selective solution-annealing of the weld zone (2, 3) of a longitudinally welded metal pipe (1). The process is especially suitable for pipes (1) having a diameter of less than 100 mm and a wall thickness of less than 2.5 mm, preferably less than 0.7 mm. In the course of the heat treatment, the weld (2) is first heated under a protective gas (1) to such an extent that its outer region (2.1) is fused. This can preferably be effected by an electric arc (7). Subsequently, the weld (2) is selectively held by further heating means (8), for example further arcs, infrared emitters or induction coils, for a presettable period under a protective gas (I) at least at a temperature (Tmin) required for the solution-annealing of the pipe material, but below the melting temperature (Ts) at least in the inner region (2.2) of the weld (2), and then cooled (10) under a protective gas (I). The single or multiple incipient fusion of the outer region (2.1) of the weld (2) does not reduce the quality of the heat treatment in the inner region (2.2), so that the desired corrosion resistance in the latter does not suffer. However, the partial fusion facilitates rapid introduction of heat for heating up the weld. <IMAGE>

Patent DE-3917375-A1 (DE)
Title: Method for inhibiting triggering pulses
Inventor: WAEGNER HANS-JUERGEN DIPL ING
IPC: H02H7/085
Filed: 1989-05-29
Abstract: The invention relates to a method which is used in integrated circuit phase-gating controllers having tacho-controlled or load-current-controlled regulation. The object of the invention is to find a method for inhibiting triggering pulses, which method allows (both in the case of tacho-controlled and load-current-controlled regulation) universally usable simple triggering pulse inhibiting, selectively with or without a restart inhibit, to be implemented, and allows the disadvantage of the known pulse inhibit to be overcome. According to the invention, the object is achieved in that a programmable logic unit is programmed by external input circuitry and controls a downstream operating voltage monitor with a pulse inhibit.   When the logic selector switch of the external input circuitry is closed, the programmable logic device operates as a threshold switch with hysteresis and, when the logic selector switch is opened, acts as a quasi RS-FF with self-latching, so that, on the one hand, no restart inhibit occurs after completion of the rectification.
