Abstract: An appliance chassis (1) contains attachment elements (52) for supporting, holding and affixing electrical and/or mechanical components (55), and, in the vicinity of certain attachment elements, has one attaching device (57) for inserting and affixing repair elements (56) assigned to the attachment elements, in the event of damage to the attachment elements. When inserted into the attaching device, the repair elements replace parts (14.1) of the holding device (14), which were lost because of damage to the attachment element.

Abstract: A video receiver is provided having a screen forecast journal with teletext data, collected from different broadcast stations and continuously updated with text pages at preset time intervals. The data is arranged in tables by programme identification and page identification and stored in memory devices, for accessing at any time. The page identifications are allocated to the programme slots, i.e. one programme identification with a page number each time. The tables can be accessed by page numbers for programmes not being transmitted at that time. A programme identification/page identification table proves beneficial for programming such page identifications. Pages are referenced by moving a cursor to margin areas of a text page. All programmes in the same time period can be paged through. Telecasts to be recorded can be selected from the pages of the forecast journal. Telecast data is transferred on a timer memory device.

Abstract: A hand-held bar-code reader (bar-code wand) which forms part of an optical reading device and is capable of being led by hand over the bar code, comprises a storage circuit for storing the data pulse train corresponding to the scanning signals, and a photo- or sound-transmitter by which the stored data pulse train is transmitted to a separate equipment, such as a video tape recorder or radio receiver provided with a photo- or sound-receiver and an evaluating circuit. In another example of embodiment, the equipment comprising the evaluating circuit, contains a reader compartment provided with a connector member for connection to the reader which, following the scanning and storing of one or more words of the character code, is returned to its compartment and is automatically read out via the connector contacts.

Abstract: The novel bar code, in the spaces (4) between neighboring code bars (1) which have a width greater than one modular width, with the modular width always being larger than the diameter of the scanning spot (55) of a reading device, contains counting-line marks (5, 6) or counting bars (7). The thickness of the counting line marks is substantially smaller than the diameter of the scanning spot, for example one third of the width of the code bars. The counting bars have a reflectance lying between that of the spaces and that of the code bars. As a result of these measures, at the output of a photo-receiver (9) of a reading device, pulses (31) of a smaller amplitude than that of the pulses (30) formed by the code bar, are generated. By these pulses there is formed a counting clock by which the decoding is rendered independent of the scanning speed.
