Title: Method and device for separating garment parts in the clothing industry
Inventor: AURICH HORST DIPL ING PROF DR
IPC: B65H3/22
Filed: 1986-05-24
Abstract: The invention relates to a method and a device for separating garment parts in the clothing industry. The aim of the invention lies in adapting the device with minimum technical expenditure to different qualities and dimensions of material. The object according to the invention is achieved in that the removal of the adhesive forces takes place beginning from the edge of a flat structure, is assisted by suitable technical means and consequently different qualities of material can be separated reliably. According to the invention this is achieved by three process steps, gripper elements being set down in the edge region of a pile of garment parts, picking up a garment part and subsequently moving it upwards by a defined distance. At the same time, a controllable air current is passed by the gripped edge of the garment part in this position in order to release edge entanglements. The garment part thus gripped is then removed from the pile of garment parts. The device used for this purpose comprises adjustably arranged gripper elements, a blower strip which is arranged movably relative to the edge of the garment parts, and elements which make defined movement sequences possible. The method and the device are suitable for use in clothing manufacture, specifically when using sewing robot technology (Fig. 1). <IMAGE>

Title: Control device for a drive assembly, comprising an engine and an automatic transmission, used to drive a motor vehicle
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: B60W30/18
Filed: 1986-09-27
Abstract: In a control device for a drive assembly used to drive a motor vehicle, with an internal combustion engine and an automatic transmission connected on the output side, means operate to influence the transmission ratio as a function of an operating parameter which is uninfluenced by driving performance and fuel consumption. When a critical value of the operating parameter occurs, the said means produce an increase of the engine speed by adjusting the transmission ratio, set taking into account the engine torque, speed of travel etc. In order to allow the engine to operate with optimum consumption at low speeds but at the same time to supply auxiliary units, not associated with the engine, with sufficient drive energy when required, at least one, especially an additional operating parameter unrelated to the engine is used.
Patent DE-3637568-A1 (DE)
Title: Laser machine tool
Inventor: FREY MANFRED
IPC: B23K26/14
Filed: 1986-11-04
Abstract: The laser beam (3) of the laser machine tool, after passing through a nozzle (5) in a focused manner, strikes the workpiece (4) to be machined, in which it burns a hole for example. A gas can come out with the laser beam via the nozzle orifice (6). The gas can be used at least partly for cooling purposes. Intensified cooling of the instantaneous burning point is obtained if additional fluid is supplied outside the nozzle. The additional fluid should strike the instantaneous burning point as accurately as possible. This is best achieved if the tapering, in particular conical or frustoconical, nozzle (5) is surrounded by a sleeve (8) and the fluid is allowed to flow between nozzle and sleeve. The direction of flow is thereby exactly predetermined. It is advantageous if only individual fluid jets come out which cross approximately in the area of the instantaneous burning point. This is achieved in a simple manner by longitudinal grooves (11) being made in the outer circumference (10) of the nozzle (5) and/or in the inner circumference (9) of the sleeve (8). The longitudinal grooves (11) are then covered by the respective other part to form longitudinal passages. Increased demand for fluid is satisfied by lifting the sleeve (8) slightly from the nozzle (5) towards the workpiece, a screwing motion being given preference to a longitudinal displacement for sensitive metering. <IMAGE>

Title: Electrical switch
Inventor: FAUDE LOTHAR
IPC: H01H3/20
Filed: 1986-11-14
Abstract: The electrical switch, which is preferably provided for installation in an electric hand tool and has a switching mechanism (1) of conventional type has an operating device (3) which can pivot against the force of a restoring spring (16). In addition, the operating device (3) can be displaced against the force of an additional restoring spring (19) whose line of action runs approximately at right angles to that of the restoring spring (16). For this purpose, the operating device (which is constructed as a single-armed lever) is supported by means of a bolt (10) and at least one elongated hole (12) such that it can rotate and can be displaced, the longitudinal axis of the elongated hole running approximately in the direction of the line of action of the additional restoring spring (19). A switching-on inhibiting device (25) prevents undesired operation of the switch, for example in the event of an electric hand tool which is equipped with such a switch being placed down or lifted up. A switching-off inhibiting device (32) makes it possible to latch the operating device (3) in the changeover position of the switching mechanism (1). In addition, a device is also provided which makes it harder to reset the operating device (3), as a result of the force of the spring (16), in the event of the manual force being reduced and the operating device (3) not being latched. This device consists essentially of a steel bolt (31) and a resetting incline (30) on the inhibiting element (26). <IMAGE>

Abstract: The invention concerns a data transmission device (2, 3), which is arranged between a data terminal device and a transmission network, and is controlled by control commands, which it receives from the data terminal device (DE) and which are inserted in the data stream to be transmitted. According to the invention, means (5, 9) are available to recognise whether pauses are included in the incoming data stream. A buffer memory (9) stores the most recently arriving data words, and, after a pause has been recognised, the data words which were most recently written to the buffer memory are compared with code words which signify a command to switch from a data transmission operating mode to a control operating mode. <IMAGE>
Patent DE-3643377-A1 (DE)
Inventor: KINDL KLAUS DIETER
IPC: C03B23/09
Filed: 1986-12-18
Abstract: A glass tube (10) with an inner thread (16) in its end section (12) can be screwed to a second glass tube (20) with an outer thread (22), together with a pressure-tight annular seal (26). A process for producing such a glass tube is also disclosed, as well as a device that is particularly suitable for implementing this process. At a distance from the thread (16) a radially projecting annular bearing surface (32) is arranged on the inner surface of the glass tube (10), adjacent to a thicker walled section (18) of the glass tube (10) that has the same inner diameter (24) as the bearing surface (32), whereas the outer diameter (34) of the glass tube (10) is essentially constant. The inner thread (16) and the thick-walled section (18) are formed in a single operation inside the glass tube (10) by plastic deformation. The deformation is essentially effected by uniformly pressing the heated glass tube (10) on a mandrel-shaped moulding body (130) by means of several shaping rollers (86, 96, 98, 100).

Title: Hydrostatic-mechanical wheel drive
Inventor: REISCH JOHANN
IPC: F16H47/04
Filed: 1987-03-07
Abstract: Hydrostatic-mechanical wheel drive for vehicles used in agriculture and/or the building industry. Wheel drives of this type, which provide two forward speed ranges and one reverse speed range, have a relatively low efficiency, especially at low speeds of travel, and their large overall volume makes them difficult to accommodate in the vehicle. The reason for the low efficiency is essentially a certain power demand in the hydrostatic part of the system, the so-called lost power which is not available at the wheel-drive output. In order, on the one hand, to achieve complete elimination of the lost power and, on the other, to be able to operate with optimum efficiency in each of the speed ranges, various measures are proposed which limit the required swivelling range of the primary hydrostatic machine to one direction, starting from the "0" position and thus result in a reduction of the overall volume. This wheel drive is especially suitable for those vehicles which, for a large part of their operating time, are driven at relatively low speeds of travel, which are quite often interrupted by operating phases at higher speeds of travel. <IMAGE>

Abstract: A watering device (10) for fowl and small animals comprises a valve housing (12, 14) having an inlet (56) an outlet (18) and a valve chamber (24, 26, 42) between them. The valve chamber includes a valve element (74) and an actuator (68, 70) for the valve element extending out of the outlet (18). A flow restricting plunger (80) is located in the inlet. The plunger (80) preferably includes deformable retaining elements (84) to allow its insertion into but prevent its removal from the housing once inserted therein. As shown the lower end of the plunger (80) rests on the valve element (74) and its upper end extends above the inlet. The diameter of the plunger is preferably sufficiently less than that of the inlet passageway so as to permit continuous fluid flow to the valve element, but at the same time prevent larger particles of debris from passing into the valve housing. As the valve is actuated, the plunger slides vertically within and above the valve housing so as to prevent clogging of the fluid flow by the larger debris particles. <IMAGE>
