Title: Hearing aid with exchangeable decorative covering - has two=part housing linked by retention plates which can grip ear lobe
IPC: H04R25/02
Filed: 1991-05-21
Granted: 1992-07-16
Abstract: The hearing aid is worn on the ear together with an exchangeable ear-ring which conceals the aid. The ear-ring (1) carries a retainer element (3) on its rear side facing towards the ear (2) and is releasably fixed to the hearing aid. The latter comprises two housings (4,5) fixed by means of retainer plates (7,8) interconnected via a hinge arrangement (6) or similar element so that one retainer plate (7) forms a clip and the second retainer plate (8) rests against the opposite side of the ear-lobe (9). The first housing (4) of the hearing aid is arranged on the rear face of the clip retainer plate (7) and the other housing (5) on the exposed face of the second retainer plate (8). ADVANTAGE - Can be used with different types of ear rings.
Patent DE-4121572-C1 (DE)
IPC: B29C63/00
Filed: 1991-06-29
Granted: 1992-12-03
Abstract: A conveyor belt is described, which has a support fabric, which is provided with at least one thermoplastic material coating and is characterized in that onto its cutting edges is welded a thermoplastic, strand-like profile material, preferably a round cord so as to constitute an edge protection. Due to the fact that the strand-like profile material (round cord) has a lower melting point than the thermoplastic material of the coating, during welding, substantially no deformation occurs in the coating, even in the vicinity of the contact faces, whereas the profile material having a lower melting point is deformed and adapts to the shape of the cutting edge of the conveyor belt and covers the same. The inventive method makes it possible to economically provide individual endless and finite conveyor belts with an edge protection when this proves necessary.

Title: Text data input method for telecommunications appts e.g. telephone - using symbol input keys and function keys to control information displayed
IPC: H04M1/247
Filed: 1991-11-08
Granted: 1993-04-01
Abstract: The input procedure is initiated by the input key (E) and this key can assign symbol input functions to the function keys normally used in other ways. A complete set of signs for the input of a text appears in several lines (ZA) and one of the lines can be selected by the line keys and provided with a recognition sign before the symbol input keys are pressed which gives the letter to be includes in the test display (TA). This can then be sent off by pressing the start key (ST). ADVANTAGE - With minimum of additional keys there can be a wide selection of visible signs or symbols, since each symbol input key is used for  number of symbols.
Patent DE-4217093-C1 (DE)
IPC: G05D1/02
Filed: 1992-05-22
Granted: 1993-07-01
Abstract: The invention describes a device and a process for exploring an unknown working area. It is not necessary for this purpose to make any markings in the area before using the device and the area does not have to have any special characteristics for determining location. The described device of the invention takes markings with it, for example metal plates or a power supply cable which it lays out while it moves around a boundary of the area. It then turns around and moves back along the marking, laying out new markings. On encountering the next wall of the area it turns, takes up the previously laid out markings and lays new ones. This process continues until the entire area has been covered. An example of the use of the device could be an industrial vacuum cleaner for cleaning carpeted floors.

Abstract: A process is disclosed for generating linear data from measurement values correlated to specific characterisitc values of a measurement object. The thus obtained measurement values are coded point by point and are stored in an oriented matrix. The individual elements of said matrix are iteratively tested for predetermined correlations, and the elements which satisfy the predetermined correlation are gathered into groups of point coordinates which define each a continuous line. The thus generated continuous lines are then graphically represented.

Abstract: The plug-in socket connection which is secured against axial forces serves for the connection of the spigot end (3) of a pipe, which can be inserted, with radial play, into the socket end (2) of another pipe. Arranged in the socket end is a sealing ring (8) and a clamping ring (14) which is designed separately from said sealing ring and has a multiplicity of clamping segments (15) which are arranged at mutual spacing in the circumferential direction and which exhibit a convex outer surface (17) and, on their inner surface (18), in each case one toothing arrangement (19), said toothing arrangements, when axial forces arrive, by interaction of the convex outer surface (17) with an inner surface (18), tapering conically to the end, of the pipe socket, press radially against the spigot end (3). Integrally formed on the clamping ring (14) is a retaining part (20) which can be fixed at the socket end, bears the clamping ring and consists of elastomer. A design which permits satisfactory gripping is achieved if the annular-disc-shaped portion (23), which comes to bear on the socket end surface (22), is designed in a reinforced manner, belongs to the retaining part and from which there extends the connecting portion (24) leading to the clamping ring (14), is assigned a steel ring (28) which increases the bending strength thereof. In particular in the case of relatively large nominal widths, it is expedient if the clamping ring (14) is provided with a circumferential cutout for receiving a flexurally rigid supporting ring (31) consisting preferably of steel. <IMAGE>

Title: Cleaning transformers contaminated with PCB
Inventor: RUSBUELT PETER
IPC: B01D1/00
Filed: 1994-08-05
Granted: 1996-02-29
Abstract: Cleaning of discharged or pre-cleaned transformers contaminated with PCBs comprises using a hydrocarbon solvent dissolving PCBs applied with heat supply using a rotary evaporator in the gas phase, subsequently condensing the hydrocarbon solvent enriched with PCBs, and removing the solvent from the transformer under a recycling feed and opt. mixing with fresh solvent. The novelty is that the solvent vapours are fed almost without pressure from the cascading evaporator in a heating bath via a separator into the transformer. The feed pipe of the evaporator opens out in the heating bath into outlet pipes of large dia. The solvent condensate enriched with PCBs is fed via the cascading tubular evaporator to the separator and the vapours recycled. An appts. for carrying out the above process is also claimed.

Title: Bending method for plate shaped workpiece, involves stopping return movement of bent workpiece before force with which workpiece is clamped between die and punch falls below predetermined value
Inventor: LIET CORNELIS HENDRICUS
IPC: B21D5/02
Filed: 2000-05-16
Granted: 2000-11-20
Abstract: The return movement of a bent workpiece (1) is stopped before the force with which the workpiece is clamped between a die (2) and a punch (5) falls below a predetermined value. The next bending step is performed until the bending angle that is measured upon the return movement remains smaller than a desired bending angle plus the desired tolerance.  The desired bending angle and the desired tolerance are fed to a processing unit. The processing unit moves the punch and the die in successive bending steps. Each bending step comprises the step of bending the workpiece at a desired bending angle minus an angular value. The angular value is increased with each step.An Independent claim is also included for an apparatus for bending workpieces.
