Title: Process for producing combs and ornaments for the hair
Inventor: WEGENSTEIN RUDOLF
IPC: B29D21/04
Filed: 1988-08-10
Abstract: For the purpose of producing combs of a sawn configuration, a strand (S) in strip form is produced in a screw extruder (1) from a thermoplastic material in granular form. As long as it is still warm and plastically deformable, this strand is calibrated in its thickness in a calibrating device (12). Subsequently, the strand (S) is subdivided by means of a cutting device (16) into sections (A), which are then fed by a conveyor (20) to a press (18). Here, the still warm and plastic sections (A) are re-shaped into plaquettes, which already have the comb profile, the teeth of which however are still connected to one another by webs. After the embossing operation, the plaquettes are punched, provided with a façonné finish, sawn and further processed. In comparison with the combs produced by conventional methods in sawn configuration, the combs produced by the novel process are considerably less expensive and the desired three-coloured tortoiseshell imitation can be accomplished with outstanding quality.   <IMAGE>

Title: Coloscopy simulator
Inventor: KUBIN SIEGFRIED DR MED
IPC: G09B23/28
Filed: 1988-10-11
Abstract: The invention is based on the object of providing the doctor which is engaged in endoscopy training with a coloscopy simulator by means of which coloscopic techniques can be learnt without risk; in addition, anatomic position variants which are difficult to pass with an endoscope, (such as formations of kinks or loops) can also be set and the manual splint manoeuvres which also are often required during examinations can be learnt. Tension/pressure sensors are fitted to intestine (bowel) sections which are mechanically highly loaded by the coloscope, which sensors control coloured light-emitting diodes depending on the intensity of the rising load, so that the pains of different intensity which arise in natura can be represented optically and the trainee can learn corresponding relief manoeuvres for the bowel. The watertight plastic box can be filled with various materials, such as water, Styropor, expanded clay (foamclay) spheres, or the like so that different degrees of mobility can be simulated for the large intestine. Artificial polyps can be introduced into the model of the intestine, the polypectomy of which polyps can be trained using conventionally available polypectomy loops.

Title: Mutual interlocking of a large number of automatic circuit breakers
Inventor: BAGINSKI PIERRE
IPC: H01H33/52
Filed: 1988-12-08
Abstract: Three automatic circuit breakers (10, 12, 14) of an electrical system having two current sources and two loads are mutually interlocked by means of a device such that parallel connection of the two current sources is prevented by the third automatic circuit breaker being interlocked in the open position when the two others are in the closed position. The closure of the automatic circuit breaker results in the pivoting movement of a first lever (24) whose movement is transmitted to the third levers (40) of the two other automatic circuit breakers. These third levers assume a position in which they control the interlocking of a second lever (32) when they have received the displacement movement caused by the two other automatic circuit breakers being closed. <IMAGE>

Title: Impact absorber for motor vehicles
Inventor: STELZER HEINZ
IPC: F16F9/54
Filed: 1988-12-23
Abstract: An impact absorber (1) for motor vehicles is described which is composed of a cylinder (2) with a piston (5). The piston (5) has an aperture (7) and separates the interior of the cylinder (2) into a low-pressure chamber (6) and a high-pressure chamber (8). A fender (4) which is fastened to a piston rod (3) acts on the piston (5). The cylinder (2) has a bush (13) which is situated on its side opposite the fender (4) and has an annular chamber (12) which is moulded onto the inside circumference. The said annular chamber (12) is connected via a bore (11) to an equalising chamber (10) which is situated inside the cylinder (2) and is separated from the high-pressure chamber (8) by means of a displaceable separating piston (9). The annular chamber (12) is sealed off from the outside by a prestressed rubber-elastic annular body (14). The annular body (14) is seated with an inner sleeve (15) on a pivot pin (16) which is fastened to the vehicle frame. As the impact speed increases, the cylinder (2) is displaced, together with its bush (13), with respect to the pivot pin (16). In this process, the annular body (14) is deformed, forming a gap (17) on the annular chamber (12) to permit the emergence of gas. In this manner, the shock to which the motor vehicle is subjected at high impact speeds is reduced. <IMAGE>

Title: Production apparatus with change pallets
Inventor: BALD HUBERT
IPC: B23Q16/08
Filed: 1989-02-01
Abstract: Workpieces are to be mounted on change pallets in an orientation station and are to be orientated with regard to certain dimensional features relative to the change pallets in such a way that the workpieces, after the transfer of the change pallets to a machining station, assume an extremely accurate, predetermined position there. Ultra-precise positioning of the workpiece can be achieved by applying a new positioning technique, working free of play and in an extremely accurate manner, for the pallet positioning as well as by applying a method according to which the systematic errors of all members affecting the accuracy (e.g. concentricity errors of the bearing arrangement of rotary tables) are determined and are compensated for during the orientation of the workpiece in the orientation station. Used during workpiece exchange by means of pallets with especially high demands on the orientation accuracy, e.g. during the exchange of gears to be accurately machined on gear-cutting machines.
