Title: Gusseted bag with integrated handle, and method and device for producing gusseted bags with an integrated handle
Inventor: PFIZENMAIER MICHAEL
IPC: B65D33/06
Filed: 1988-02-03
Abstract: A gusseted bag (10) with an integrated handle has a bag body (12) consisting of two side parts (16, 18) which are connected via lateral longitudinal seams (38, 40) and which merge into one another in a closed, transversely running end via a bottom fold (22) pointing into the interior (13) of the bag body (12) when the bag (10) is empty. A carrying handle flap (14) is arranged at the closed end, and the opposite end is open to introduce the product to be packaged, which end is closed when the product has been introduced. It is proposed to form the carrying handle flap (14) and the bottom fold (22) from a single fold (30) which is separated by two transversely running support seams (34, 36) in each case between the side part (16 or 18) and the adjacent part (29 or 31) of the fold (30) into the inwardly directed bottom fold (22) and into two loop-like carrying-handle folds (26, 28) directed opposite each other and forming the carrying handle flap (14) (Figure 3). <IMAGE>

Title: Improved window/headlamp washing system for vehicles
Inventor: BOEKEMEIER URSULA
IPC: B60S1/52
Filed: 1988-05-25
Abstract: The conventional window/headlamp washing systems in vehicles, in particular passenger cars and lorries, are constructed in such a way that a jet of fluid is sprayed onto the window/headlamp to be cleaned via spray nozzles attached to the body of the vehicle, in order to improve the wiper power of the window/headlamp wiper on a window which is dirty or dry. This method requires a large consumption of water, leads to water marks in the regions of the window/headlamp which are not in the area of action of the wiper and to soiling of the body of the vehicle. The improvement presented here provides for the cleaning fluid to be fed via a line system directly into the area of the wiper or wiping blade and to be applied directly onto the window/headlamp. This can take place for example in such a way that the wiper arm contains a pipe which is coated with insulating material. The said pipe opens in the centre of the wiper blade. In this arrangement, the wiping blade can be manufactured with a double lip, for example in such a way that the rubber profiles of the double-lipped wiping blade and the window/headlamp to be cleaned form a cavity which is similar to an elongated half-cylinder. Cleaning fluid is sprayed or pumped into this cavity as required via the line system described above whilst the wiper is activated.
Patent DE-3819816-A1 (DE)
Title: Covering profile for an awning
Inventor: ROEDELBRONN HORST
IPC: E04F10/06
Filed: 1988-06-10
Abstract: The invention relates to a covering profile for an awning which is to be fitted on web-like retaining brackets which are connected on a building wall. Conventional manners of attachment provide, on the inner side of the covering profile, bent-off channels with screw nuts which can be displaced therein, with the result that, in the case where the retaining screws are to be screwed in overhead, said screw nuts are difficult to locate. In addition, a relatively large amount of securing is necessary in order that the covering profile can be brought to bear under stress. The invention solves these difficulties by a two-legged threaded moulding which is arranged on the inner side of the covering profile, as parallel to the longitudinal direction and in which the retaining screws engage in any position provided that the covering profile is in its given position in relation to the building wall. By means of the same retaining screws, a clamping action can be achieved which renders superfluous otherwise necessary securing measures.

The gripping arms (12, 14) are closed by opening the shut-off valve (64), in the course of which the closing speed of the gripping arms (12, 14) can be influenced by the degree of opening. <IMAGE>

Title: Method and device for controlling the excitation current (energising current) during the switching-off process of electromagnets
Inventor: CLAUSSEN HANS-JUERGEN DIPL ING
IPC: H01F7/18
Filed: 1988-11-25
Abstract: The invention relates to the prevention of remanence phenomena during the process of switching electromagnets off. The invention is used especially in the case of load-lifting magnets and rolling mill turning magnets. The object according to the invention is achieved in that the magnetic zero crossing after initiation of the opposing excitation is detected in order to disconnect the demagnetisation current. For this purpose, a magnetic shunt path is produced by means of a device outside the operating area of the magnet, and independently of the load to be held. The magnetic zero crossing is detected by a component which can be influenced magnetically. <IMAGE>

Abstract: The invention relates to a process for the production of a cambered contact face of an optical waveguide (optical fibre) terminating in an optical plug. Relatively large radii of convex camber can be produced in a simple manner by warming the end region of the optical waveguide, after production of an approximately orthogonal separating surface, until a pasty state is obtained with softening restricted in such a way that the face is pressed into a convex shape, at least in a central region, by surface tension without the use of moulds. <IMAGE>
Patent DE-3903242-A1 (DE)
Inventor: RUDY MARION FRANKLIN
IPC: B32B5/08
Filed: 1989-02-03
Abstract: An internally pressurizable lightweight high tensile strength multi-layered structure with an outer barrier layer envelope (12) of elastomeric semi-permeable material for use as a cushioning device is provided. The outer barrier layer is bonded at a multiplicity of sites, to substantially the entire distal surfaces of a double-walled drop-thread linked fabric (14) wherein the filaments (20) are comprised of a highly distorted, long chain, axially orientated crystalline molecular structure which has a low gas permeability. The bond between the barrier layer (12) and the facing fabric is substantially increased by the presence of fibrils (29, 30) and texturising. The drop threads (20) which are likewise texturized, function as stress averaging members to maintain the composite structure in either a substantially flat or planar or contoured configuration without weldments within the select load-bearing areas. This lightweight product is capable of withstanding very substantial internal inflation pressures, under severe long-term steady state and cyclical compression and flexural fatigue conditions. The product is inflated, pressurized and sealed and maintains the internal inflatant pressure for extended periods of time. generally in excess of the useful life of the overall product, by employing the diffusion pumping phenomenon of self-inflation. The cushioning device can selectively control the rate of diffusion pumping phenomenon by varying the density relationship between the elastomeric semi-permeable material of the envelope and the essentially gas impermeable highly distorted crystalline filament material of the fabric, thus improving the long term performance and durability and reducing the cost, and eliminating some of the disadvantages of the earlier cushioning products. In a limiting case, it is possible to permanently inflate the device using readily available fluids as nitrogen or air. Numerous applications including use as a shoe insole are disclosed. <IMAGE>

Filed: 1989-05-31
Abstract: In a semiconductor device having a semiconductor substrate layer (1) bearing several semiconductor layers (2), the surface layer (5) of which is counter-doped to form a majority charge carrier barrier, the novelty is that the semiconductor layers (2) consist of a material system with a compsn. selected such that the bandgap decreases in the direction towards the surface (6), thus avoiding the formation, at the location of the potential max.
