Patent DE-3306387-A1 (DE)
Title: Apparatus for wire drawing
Inventor: BRUEHL RUDOLF DIPL ING
IPC: B21C3/14
Filed: 1983-02-24
Abstract: Apparatuses for drawing wire comprise a drawing die and a pressure sleeve connected releasably to the latter. The pressure sleeve has a wire-passage bore coaxial to the drawing hole of the drawing die and further bores for carrying away drawing lubricants, the latter bores starting from the cavity enclosed at the division between the drawing die and the pressure sleeve and opening at the outer side of the pressure sleeve. A large-volume lubricant box is furthermore arranged around the pressure sleeve. When lubricant boxes of this kind are used, there is the problem that the surface of the wire does not take up as much lubricant as if the lubricant were applied under pressure in uniform and deep distribution to the surface of the wire. In order nevertheless to achieve a good supply of lubricant, the lubricant bores (11) are arranged parallel to the axis of the wire-passage bore (6) of the pressure sleeve (2). The pressure sleeve (2) is furthermore surrounded at its circumference by a jacket-like heater (8). <IMAGE>

Patent DE-3323638-A1 (DE)
Title: Transporting method and device for its implementation
Inventor: SCHULTE GERHARD DIPL ING
IPC: B65G15/58
Filed: 1983-06-30
Abstract: The invention relates to a method for transporting suspended flat pieces of material from a reception region to a delivery region in a transporting device with a transporting section, and to a device to implement the method. A large amount of energy is required to implement known methods if pieces of a plastic or elastic material with a relatively low weight have to be transported while suspended, and transport is often insufficiently reliable and is very noisy. According to the invention, this is avoided by sticking a plurality of needles into the pieces of material in the reception region, until, as a result of self-locking and/or positive locking between the needles and the pieces of material, a retaining force is built up between the needles and the pieces of material, which force is altogether greater than the weight of the pieces of material, by then transporting the pieces of material freely suspended on the needles and by pressing the pieces of the material off the needles or pulling the needles out of the pieces of material in the delivery region.

Patent DE-3337240-A1 (DE)
Title: Cutting insert for machine tools and a process for its production
Inventor: KURZSCHENKEL HANNO DIPL ING
IPC: B23B27/20
Filed: 1983-10-13
Abstract: A cutting insert for machine tools with a sintered-carbide substrate and a hard surface layer of ceramic or crystalline nature, preferably polycrystalline diamond or boron nitride crystallised in the cubic form is considerably improved by virtue of the fact that the sintered-carbide substrate projects beyond the surface layer and, as a result, has an exposed area. The sintered-carbide substrate preferably consists of a material which is itself suitable for cutting inserts but can be connected to the body of the respective tool by brazing or welding. After the surface layer has been used up, the sintered-carbide substrate itself can then continue to be used as a cutting insert - possibly for relatively light cutting tasks.

Title: Component for switching technology
Inventor: RECKWITZ PETER J
IPC: H01H13/703
Filed: 1984-03-09
Abstract: A film keyboard is constructed in a self-locking and largely self-reacting manner, in that the covering films have allocated to them, in the region of the key surfaces, bodies which can be excited and/or react magnetically, preferably permanent magnets. The contact is produced and released again with a definable pressure via these permanent magnets, the switching feeling being provided in an excellent manner in this case in that an intrinsic movement which can be sensed takes place when pressure is exerted in a suitable manner, which intrinsic movement is registered by the person exerting the pressure who therefore knows the contact has actually been produced. The manufacture of such film keyboards is simplified in that the lead cores are printed on and are preferably insulated by means of varnish layers. <IMAGE>

Patent DE-3413484-A1 (DE)
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/195
Filed: 1984-04-10
Abstract: Die Erfindung betrifft einen kostengünstigen Gurtstrammeraufrollautomaten, bei dem die Auslösung aus Zeitgründen nach wie vor pyrotechnisch über einen Mini-Sprengsatz (ca. 0,2 g Treibladung) erfolgt, der Strammvorgang selbst jedoch aus der gespeicherten Energie einer vorgespannten mechanischen Feder abgeleitet wird. Der Mini-Sprengsatz hat lediglich die Aufgabe, über eine Sollbruchstelle die formschlüssige Verbindung zur Arretierung der vorgespannten Strammerfeder aufzuheben, so daß die Kraftübertragung für den Gurtstrammvorgang (Gurteinzug 10 bis 20 cm bei einer Gurtkraft bis zu etwa 1000 N) erfolgen kann. Ein derartiger Gurtstrammer reduziert den Aufwand an Platz und Gewicht, insbesondere aber den Preis, sowie die Probleme mit dem Sprengstoff bei der Montage (gesetzliche Auflagen) und der Entsorgung. In einer besonders einfachen und preisgünstigen Ausführungsform übernimmt ein mech. Zünder die Zündung des Mini-Sprengsatzes und somit die Aktivierung der Gurtstrammung. Es ist weder ein aufwendiger Fahrzeugsensor, weder Elektronik, weder eine Verkabelung, noch eine Stromversorgung notwendig. Das System arbeitet autark. Eine noch einfachere Ausführungsform verzichtet auch auf pyrotechnische Mittel und bewerkstelligt die Aktivierung über einen rein mechanischen Auslösemechanismus.

Title: Lock working with magnetic means and having an associated fitting key card
Inventor: HUESTER BERNHARD
IPC: G06K7/08
Filed: 1984-09-24
Abstract: So that the coding of a key card having magnetically readable information points can be made invisible from outside and cannot be duplicated or changed without destroying it, but can be read off without movable parts, a perforated plate made of non-magnetisable material, covered on both sides by plates of non-magnetisable material, is provided in the direction of insertion with a plurality of rows of holes for magnetic sensing and identification which are ordered relative to one another according to a code system. The holes are filled with ferromagnetic material, for example circular metal discs and/or iron powder. For the laterally correct insertion of the key card into the lock, the edges of the two cover plates are connected firmly to one another in the plane of one cover plate. Each row of holes is assigned a reading head having a permanent magnet which is aligned with the holes and the magnetic lines of flux of which are varied in dependence on the position of insertion of the key card in the lock during the change between air and metal. This has the effect of abrupt changes in magnetic induction which are converted into electrical counting signals by a measurement transducer designed as a magnetoresistor and which are fed to an evaluation circuit.
