IPC: G06V10/145
Filed: 1988-08-25
Abstract: The invention relates to the use of a measuring device for the automatic reading of characters and digits which are covered with an optically transparent layer, consisting of an optical unit which generates an image on a sensor which is fed to an evaluation unit, the optical unit with its axis, in which a polarisation filter is connected, being directed onto the surface of a body, and being pivotable about the normal to the surface, with the stipulation that the observation of the data carrier is carried out at the principle angle of incidence of the layer covering the characters and digits, and the principle preferred direction of the polarisation filter lies in the observation plane. To achieve this object, it is proposed to provide a measuring device which is suitable for the automatic reading of characters and digits which are covered with an optically transparent layer. <IMAGE>

Title: Overvoltage protection
Inventor: HASSE PETER DR ING
IPC: H01T4/08
Filed: 1988-09-20
Abstract: The invention is based on an overvoltage protection of a consumer (terminal), the overvoltage protection being provided between a fused mains, especially a sub-distribution of a mains, and the consumer (terminal), which consumer may also be fused, and the overvoltage protection having a thermal release (14) protecting against excessive heating of an overvoltage arrester. In order to protect this overvoltage protection both against excessively high current loading and against excessively high heating of the overvoltage arrester, provision is made for a fuse (13) to be located in a longitudinal path (7) in which the current flows from the mains or sub-distribution, respectively, to the consumer or terminal, respectively, and for this fuse (13) to trip when the maximum current-carrying capacity of the longitudinal path (7) and/or of the branch path (12) is exceeded, and also for the overvoltage arrester (15) and a thermal release (14) which responds to heating of the overvoltage arrester and switches off the overvoltage arrester to be provided in the branch path (12) between the longitudinal path (7) and a further longitudinal path or earth (6). <IMAGE>

Abstract: The invention relates to a fastening device for detachably fastening a boom (11'), which is provided with a headpiece (12), to the mast of a sailboard by means of a tensioning means (13) embracing the mast. The tensioning means (13) cooperates with a pressure cheek (14) which is joined to the tensioning means (13) and is situated opposite the latter with respect to the mast. The pressure cheek (14) and the tensioning means (13) can be displaced with respect to one another by means of a clamping device (10) which can be operated by a swivellable lever (11, 11'), in order firmly to clamp a mast embraced by the tensioning means (13) between the latter and the pressure cheek (14) when the lever (11, 11') is swivelled out of a release position into a clamping position. The clamping device is a mechanical arrangement (mechanism) (10) which pulls the pressure cheek (14) and the tensioning means (13) apart in a positive fashion in order to release the mast when the lever is swivelled from its clamping position into its release position. The tensioning means (13) is joined to the pressure cheek (14) via the head piece (12) of the boom and the mechanical arrangement (10) arranged on the headpiece (12) of the boom. <IMAGE>

Title: Hand-held implement for combing hair or the like
Inventor: REINERS JOSEF
IPC: A45D24/10
Filed: 1988-12-27
Abstract: A hand-held implement for combing hair or the like consists of two combs one of which is moved back and forth by motor power by means of a drive arranged in the handle part and is held on one side at the front drive end and projects in a free and unguided manner. A second comb which is fastened non-movably on the housing is arranged downstream of the movable comb in the combing direction. By means of a space-saving conversion of the rotary movement of the drive shaft into a translatory movement of the movable comb, a small construction size is achieved. The parallel arrangement of a movable and a non-movable comb brings about good detangling of the hair with simultaneous gentle treatment of the hair.
