Patent DE-3223640-A1 (DE)
Title: Diecasting process and apparatus for performing this process
Inventor: HEILOS HANS CHRISTOPH
IPC: B22D17/26
Filed: 1982-06-24
Abstract: A process for the production of diecast parts, and an apparatus for performing this process, are described. In this new process, the metering of the melt for the component to be cast and the production of pressure for the injection of this melt are completely uncoupled from each other in time. A mould unit is developed which can be handled separately as a closed mounting unit with pre-metered melt already contained therein, because the mould unit is heavily heat-insulated towards the outside. Either the whole mould unit or the melt alone is then exposed to pressure, the melt being expelled into the casting mould. Preferably the mould unit is fitted with ceramic components which, owing to their great temperature resistance, their large and variable heat capacity and their very low thermal conductivity, enable very high-melting materials to be cast. It is possible with the described process or with the described apparatuses to cast different, very high-melting materials in direct succession without changeover times and in a cost-effective manner, and the shape of the part to be diecast can also vary within wide limits on successive shots.

Title: Navigation system
Inventor: MUELLER PAUL DR RER NAT
IPC: G01S5/14
Filed: 1982-07-23
Abstract: A simple navigation system for vehicles is proposed. The signals generated by satellites in accordance with the "Global Positioning System" and received by a, for example single-channel receiver (1) are evaluated and supplied as location data to a display (5). So that current position data are also available for being linked in time intervals which are needed for calculating the location data, a course and displacement sensor device (7, 6) is provided which due to the fact that its signals are only required for a very short time does not have to meet high-level requirements. The systematic drift of the course and displacement sensor device (7, 6) is suppressed by automatic drift correction by means of the signals received by the receiver (1). <IMAGE>

Title: Safety fitting for window and french-window handles
Inventor: CHALES DE BEAULIEU HERBERT
IPC: E05B13/08
Filed: 1982-08-19
Abstract: Safety fitting for window and french-window handles, which prevents small children from opening windows or french windows. The safety fitting consists essentially of a spring-loaded slide which is arranged around the square pin of the handle and is located in a slide guide fixed by the fastening screws of the handle rose and which, in the position of rest, retains the square pin of the handle non-rotatably by means of a rectangular retaining recess cut out centrally in the slide and corresponding to the square pin of the handle. By pulling out the slide with one hand on the slide handle part projecting from the slide guide, counter to the resistance of the spring, the square pin is freed by the slide recess now displaced towards the middle and the handle can be rotated through 90 DEG  or 180 DEG with the other hand. After the slide handle has been released, as a result of the spring effect the slide is immediately pushed with its rectangular recess on to the square pin again and the latter is thereby retained.

Title: Closure cap made of deformable material with an internal thread for a container neck with an external thread
Inventor: SPATZ GUENTER
IPC: B65D41/04
Filed: 1983-05-06
Abstract: The invention relates to a closure cap (6) made of deformable material with an internal thread on the inner wall of the closure cap (6) for a container neck with an external thread (2). In order to make such a closure cap more flexible and thus more capable of tolerance, the individual thread turns (9) of the internal thread on the inner wall are arranged on neck pieces (8) which are inclined towards the cap closure lid (5). Consequently, the torque required for the positive rotation of the closure cap (6) onto the external thread (2) of the container neck is less and the striking of the cap closure lid (5) against the neck rim (12) is noticeably abrupt. Therefore, such a closure cap will no longer be rotated excessively. The inclination ( alpha ) of the neck pieces is preferably between 35 DEG  and 45 DEG  in relation to the covering surface of the external thread. <IMAGE>

Title: Belt retarding section for a folding apparatus
Inventor: KOEBLER INGO DIPL ING
IPC: B65H29/68
Filed: 1983-09-12
Abstract: The belt retarding section in a folding apparatus comprises two cams of identical shape and eccentricity arranged on a common shaft. The belt which is at least partially wrapped around the two cams undergoes deflection between the latter, with simultaneous displacement from the plane of one cam into the plane of the other cam. The plane displacement is reversed by a deflection or guide roller lying in the region of the retarding section. As a result of the design and arrangement of the double cams on the common shaft, an acceleration and retardation of the belt section are achieved in the rhythm of the rotation of the cams in the retarding section, travel compensation simultaneously taking place so that no linear displacement of deflection rollers is necessary.
