Patent DE-3917671-A1 (DE)
Title: Introduction of air pressure into plastic lay flat tubing - with constant tube volume maintained by rotating injector pipe which is operated by contact switch related to tube size
Inventor: PREUSS HEINZ
IPC: B29C53/10
Filed: 1989-05-31
Abstract: Equipment for introducing air pressure into plastic tubing during the lay flat tube production process maintains a constant air volume within the processing section between the inlet and outlet rolls. An air injector is formed of a curved bow-shaped pipe with an angled nozzle and rotates about an orthogonal axis relative to the tube movement.  The injector is attached to an air pressure line and by means of a contact device for the plastic tubing is linked to an operating switch. The switch operates an air valve which at a predetermined tube volume closes off the air supply and on reduction of the tube volume opens the air supply again. The injector pipe rotates under the effect of air outflow and moves in the same direction as the tube.  Penetration of the injector nozzle into the tubing is achieved by overlapping the paths of the nozzle and the tubing. USE/ADVANTAGE - The equipment is used in the production of the lay flat plastic tubing and maintains a precise volume of air in the inflated tube between the inlet rolls and the flattening rolls at the end of the folding section.

Title: Automatic multicolour printing dryer - machine raises crates for polyethylene or polypropylene bottles after each printing and passes them through radiation heater
Inventor: ALT PETER DIPL ING
IPC: F26B3/28
Filed: 1989-09-04
Abstract: A continuous dryer ispartic.designed for the reduced drying of multi-colour printing with 2-component inks applied successively by silk screen or other method on to polyethylene/polypropylene bottle and other crates. The crates are raised by a lift from the printing machine, and the printing inks are polymerised under the controlled irradiation of an adjustable radiation system but without superficial hardening of the ink. The method can be made to function automatically. It achieves the normal degree of air drying and any added inks will not delaminate off. The drying is aided by the suction effect of an injector integrated into the air duct. The system overcomes the problems that are associated with multiple colour printing and drying the successive inkings. The figures show. the lift (1), the irradiator (2), lift forks (3) free from shadowing, drying and cooling lengths (4,5,6)and air duct (6) injectors.  ADVANTAGE: The method does not produce a surface polymerisation but one which is reduced in the total depth of colouring.  The pores of the ink surfaces thus remain open and ensure that any additional inks will adhere firmly.
Patent DE-3933425-A1 (DE)
Title: Prodn. of tubular coil holder - by mixing epoxide] resin and iron particles, centrifuging mix inside tube and curing to form uniform void free product
Inventor: MAYER EBERHARD DR
IPC: H01F41/02
Filed: 1989-10-06
Abstract: Tubular coil holders are produced from a mixture of iron and cast resin. In the process the mix of resin and iron particles is cast in a tube which is closed off and centrifuged at such a speed that the iron particles plus a certain amt.  of resin reaches a stable state allowing the tube formed to be cured outside the centrifuge. The cast resin is pref. an epoxide and the forming tube is pref. made of plastic material. The constituents are mixed in the proportions of e.g. 130g epoxy resin and 450 g iron particles. The tube (11) is filled partly with the mix (10) and both ends are plugged with component (12,13) fitted with journals (14,15) by which the tube is held in a centrifuge. It is rotated at 10,000 rpm or similar speed according to the viscosity of the resin. The powder becomes consolidated as a layer on the side of the tube (11) which contains a small quantity of the resin but no voids. The tube is heated to cure the resin, the cast tube is removed and machined as required. ADVANTAGE - The method largely eliminates the formation of voids in the products. It distributes the iron particles uniformly through the resin so that the properties of the product can be reproduced.
Patent DE-4001474-A1 (DE)
Inventor: GIBTNER SIEGFRIED DIPL ING
IPC: F02P5/153
Filed: 1990-01-19
Abstract: The invention relates to a knock control system of a spark ignition internal combustion engine having a short-time control during which, on occurrence of instances of knocking, the value for an actual ignition point starting from a characteristic map input is reset by a control stroke in the direction of retarded ignition. In the absence of instances of knocking, the actual ignition point is moved by a control stroke in the direction of advanced ignition back to the characteristic map input. According to the invention, a long-time adaptation is provided in that the characteristic map input (1), upon the occurrence of instances of knocking (K), is reset or modified by an adaptation value (LZ) away from the knock limit so that the short-time control is referred to a new ignition point input or a different level. The adaptation values (LZ) are acquired in dependence upon the instances of knocking arising during a monitoring interval. Suitable variables for acquiring adaptation values are the mean values of the control strokes in the monitoring interval in question.

Filed: 1990-06-11
Abstract: The invention concerns a device for extracting pacemaker electrodes, the device having a handle (7') at the rear end of an approximately 70 cm long metal tube (2) through which an internal wire (1) runs, extending about 1 cm out beyond the end of the tube (2). Located at the free end of the internal wire (1) is a retrieval head (K) whose claws can be opened by exerting an opening force on the retrieval head (K) via the metal tube (2), the internal wire (1) being held stationary. At the end remote from the retrieval head, the internal wire (1) is fitted with a connector (18) which is mounted in the handle (7') so that it moves rotationally and translationally. The connector (18) can be set in rotational motion by a drive motor, thus enabling the opened retrieval head (K) to be withdrawn from the pacemaker electrode by rotation if the electrode cannot be extracted from the tissue of the patient.

Title: Insulated piping connection - has conical pressure surfaces and insulation to maintain spark gap to prevent electrical flow or voltage potential
Inventor: GOTTFRIED JOSEF DIPL ING
IPC: F16L25/02

The inner conical connection (2) has a section (10) without insulation at a gap from the non-insulated outlet (19) of the drilling which matches the path of the outer nominal spark gap (13). A sliding disc (20) is inserted to prevent rotation between the inner conical connector (2) through the pipe connector (4) section, to press into the conical inner drilling (7) of the mantle body (1). Drillings are in the screw threading (16), for locking pins (21) to prevent the piper connector (4) from unscrewing. ADVANTAGE - Despite the high forces required to lock the pipe sections together, the required spark gaps are maintained in a connection with high temp. resistance, in a simply completed assembly action.
