Patent DE-3814460-A1 (DE)
Title: Decorative panel
Inventor: BAYER PETER
IPC: E06B3/68
Filed: 1988-04-28
Abstract: Decorative panels which consist of plastic or glass elements with a lead mounting are customarily hung in front of the windowpane by means of chains or straps. The optical impression thereby achieved is unsatisfactory, because it is too clearly recognisable that the decorative panels are not incorporated into the window in the same way as genuine leaded glazing. The new decorative panel is to be attachable to a window in such a manner that the optical impression of genuine leaded glazing is produced. In order for the decorative panel (1) to be attached to a window which is provided with bars, it consists of two panel sections (6a-6d), which are spaced apart by at least the width of conventional window bars (3, 4), the fixing device consisting of approximately U-shaped retaining clips (7) which bridge the distance between the panel sections, are fixed to the lead mountings and project beyond the level of the lead mountings (9) on one side of the decorative panel. The decorative panel is particularly suitable for embellishing modern windows which are often plain. <IMAGE>

Title: Membrane switch
Inventor: BECK GERHARD DIPL ING
IPC: H01H13/702
Filed: 1988-05-11
Abstract: A membrane switch consists of a support with conductor tracks which belong to a circuit and are interrupted in the region of the switch, and of a switching membrane which is arranged at a distance above said support and has corresponding conductor tracks on its side facing the support, as switching links, which close the circuit on the support when pressure is exerted on the switching membrane. In order to achieve an optical indication of the switching process without enlarging the structural height of the membrane switch, the switching membrane is assigned an electroluminescent device, which consists of a transparent covering membrane with a first electrode, a membrane which is permanently connected thereto and has a second electrode, and a layer which is arranged in between them and consists of pigments which luminesce in an alternating electrical field, the electrodes being located in an interrupted circuit which is closed when the switching membrane is operated.
Patent DE-3818276-A1 (DE)
Title: Needle print head for matrix printers
Inventor: OTT HUBERT ING GRAD
IPC: B41J2/275
Filed: 1988-05-30
Abstract: A needle print head is proposed, which corresponds in its construction to a conventional hinged-armature system. These systems are inexpensive compared to mixed magnetic systems and uncomplicated in terms of the production technology. Previously it has been disadvantageous in the hinged-armature systems that wear and jamming had to be prevented by means of a foil between the magnet armature and the magnet yoke, thus enlarging the air gap. In particular, however, it was not possible to increase the torque acting on the armature because the armature bearing point lay either on the edge of the yoke or the magnet pole surface. These disadvantages reduced the degree of efficiency of the hinged-armature systems and thus the printing performance of the needle print head. The design according to the invention eliminates these disadvantages in that the magnet yokes are surrounded by an anti-wear element. The armature bearing point can thus be shifted away from the magnet pole surfaces to the anti-wear element so that the poles can act on the armature with a greater torque. In this case, iron-containing abrasion at the armature bearing point is prevented completely and the magnet pole erosion is reduced considerably.

Title: Method of protecting computer programs from illegal use
Inventor: HOEHNE BERND
IPC: G06F21/00
Filed: 1988-08-23
Abstract: For protecting computer programs from illegal use, known methods such as copy protection and linkage of programs with computer components have been unsuccessful. They have disadvantages such as incompatibility, expensive modifications, difficult handling or failure. The new method permits copying of programs without restriction. The protection is in the combination of the program with a physical key. The medium is a diskette, which has mechanical modifications, which are decoded using a diskette station. The program to be protected can be started, after the user has been authorised, only by inserting the key diskette. It is also possible to record the program start on the key diskette, to prevent other starts of the program on other devices. The mechanical modifications are unusable sectors, the position of which defines the key. Key diskettes can be manufactured without great cost, but cannot be reproduced without considerable mechanical cost. The security method is particularly suitable for programs for personal computers or stand-alone computer systems. No additional equipment is necessary, since diskette drives are standard on personal computers. However, the method can be used anywhere where a diskette station can be connected.
Patent DE-3829691-A1 (DE)
Title: Multi-gear hub
Inventor: BERGLES EDUARD ING
IPC: B62L5/02
Filed: 1988-09-01
Abstract: The invention relates to a multi-gear hub having more than three gears and having a back-pedal brake device for bicycles or the like. The shifting system which is used in these configurations of a multi-gear hub having a two-stage planetary gear mechanism, and which can be controlled by means of a thrust block guided in a slot in the hub axle, has an axially displaceable shifting sleeve directly on the hub axle and a shifting shell which is coaxial with the said shifting sleeve and is likewise axially displaceable, both of which can be controlled by means of the thrust block. In this arrangement, the shifting sleeve serves at least for alternate fixing of one of the two sun wheels on the hub axle, the shifting shell on the one hand participating in a controlling manner in the coupling operation and on the other hand being configured so as to be capable of acting on the hub transmission elements in the displacing sense and thus in the shifting sense. The control of the hub is effected by means of a single shifting element. The actuation of the integrated back-pedal brake device takes place completely independently of the gear stage shifted in each case. <IMAGE>

Patent DE-3839713-A1 (DE)
Title: Cargo ship, in particular a container ship
Inventor: SPRINGHORN MANFRED DIPL ING
IPC: B63B19/14
Filed: 1988-11-24
Abstract: In the ships referred to here, the requirement is to transport containers (32, 33) of different size in a secured manner in cellular frames. However, it has been found that, in the case of the known cellular frames firmly installed on board, only one load consisting of a certain number of containers (32, 33) of a certain size can be accommodated, but in practice this load will scarcely be available for any particular trip. Therefore the existing stowage space in ships with fixed stowage frames can scarcely be utilised in practice. In addition, it has proven to be problematic to open cellular spaces (37, 38) of different size in the hold (31) without any difficulties for loading and unloading using conventional, movable hatch covers (44). To solve the abovementioned problems, the invention provides a hatch-cover arrangement which has a (larger) rolling cover (46) of conventional type of construction and a (longer) lifting cover (47) which can be shortened by a hinged section (50) for clearing sufficiently large sectional areas of the hold opening (39). Furthermore, cellular spaces of different size of the cellular frame can be formed by cell walls (68) movable in the hold (31) or on the hatch covers (44). The invention is especially suitable for all-container ships (30). <IMAGE>
Patent DE-3841030-A1 (DE)
Inventor: HEN JOHN
IPC: C09K8/528
Filed: 1988-12-06
Abstract: A method for inhibiting the formation of scale in a well penetrating a subterranean formation for the production of fluids from the formation comprising injecting into the formation an acidic aqueous solution having pH no greater than 3 containing a mixture of a polyacrylate scale inhibitor having a molecular weight range from 500 to 10,000 and a polyvalent cation wherein the equivalent ratio of polyvalent cation to polyacrylate scale inhibitor is less than or equal to 0.5 in the acidic aqueous solution and allowing natural conditions in the formation to raise the pH of the solution an amount sufficient to cause controlled precipitation and increased deposition of the scale inhibitor in situ in the form of the polyvalent cation- polyacrylate complex. The scale inhibitor solution employed in this method avoids premature plugging of the formation, substantially extends the life of the treatment and the polyvalent cation complex of the polyacrylate is fully inhibitive.
Patent DE-3903886-A1 (DE)
Title: Coupling sleeve for the ends of coaxial cables, especially in broadband communications cable lines
Inventor: SCHLUETER DIETER
IPC: H01R13/646
Filed: 1989-02-10
Abstract: In the case of such a coupling sleeve, the outer conductors which are to be electrically connected to one another are electrically connected via the sleeve casing, while the inner conductors are connected by means of an axial plug pin in the cable-end connectors on both sides when they are inserted into a contact holder in the interior of the sleeve, which is held there by insulating bodies. In order to ensure simple handling and that contact is made reliably, it is proposed to form the insulating bodies from an axially continuous tube which is longitudinally split into a plurality of shells which hold between them longitudinally corrugated spring tongues as a contact holder. The tube is provided with radial orifices and is primarily equipped with radial support feet which are supported on the inner surface of the sleeve casing. The sleeve casing has pressing-in points which are arranged in a pattern corresponding to the arrangement of the feet. These form a type of female closure half for a snap-action connection during final assembly, while the radial feet can be deformed elastically and at the same time form the male closure half.
