Title: Heating device for the electrical planar heating of the rear surface of exterior mirrors
Inventor: ALTMANN DIETER
IPC: B60R1/06
Filed: 1981-10-08
Abstract: The invention relates to a heating device for the electrical, planar heating of the rear surface of, in particular, motor vehicle exterior mirrors. In accordance with the prior art, motor vehicle mirrors are heated in two stages, specifically in separate surface sections. This has the disadvantage that the non-heated surface section can mist up. There is provision for two heating circuits (2/3), of differing power, which are guided inside one another with constant spacing to be arranged on the surface (1) to be heated, the lower power heating circuit being constructed as a permanent heating circuit (3) and the higher power heating circuit being constructed as a switching heating circuit (2) controlled by a thermoswitch (4). The thermoswitch (4) takes up the temperature from both heating circuits (2/3). This construction ensures that in each case the complete surface is heated, specifically irrespective of whether only the permanent heating circuit (3) or at the same time the switching heating circuit (2) is switched on. <IMAGE>

Patent DE-3148219-A1 (DE)
Title: Auxiliary device for producing abutments for building roofs
Inventor: KRIEGER AUGUST
IPC: E04B7/04
Filed: 1981-12-05
Abstract: The invention relates to an auxiliary device for producing abutments for receiving inferior purlins which are connected to the rafters of a building roof. Abutments for rafter roofs are frequently cast from concrete in the construction method customary today. In practice, difficulties constantly occur in this case while producing the abutments, since the latter have to be erected so as to fit precisely in the angle of the roof slope. The object on which the invention is based is to provide an auxiliary device which permits the production of an abutment which is aligned precisely in terms of angle. This object is achieved according to the invention in that a displacement element on which a support for inferior purlins is articulated so as to be pivotable and fixable about a horizontal axis is adjustable in height and lockable on a vertical guide element. With this auxiliary device, it is possible to set any desired roof-slope angle in a simple manner and at the same time to align thereby a formwork, which is required for the abutment, for filling with concrete.
Patent DE-3200291-A1 (DE)
Title: Digital speed error compensator
Inventor: KATO TETSURO
IPC: H04N9/896
Filed: 1982-01-07
Abstract: The invention relates to a speed error compensator for compensating speed errors which are contained in video signals, the timebase errors of which can be corrected by means of conventional timebase correction devices. A conventional speed error correction device works by detecting the speed error in each horizontal line interval of the video signal read out of the memory in a timebase correction device. This speed error signal is usually a voltage which is a function of the phase difference between the write clock pulses, which are synchronised with the incoming video signals supplied to the timebase correction device, the phase of these pulses remaining fixed over an entire horizontal line interval, at the phase of the usual colour burst signal which is present at the beginning of the next line interval following. This voltage is then integrated over a horizontal line interval, the progressively rising integrated voltage being used for changing the phase of the read clock pulses which are used for reading the video signal out of the timebase correction memory. In the invention, the phase of the read clock pulses remains the same and the level of each scan read out of the timebase correction device is set. In particular, the level of each scan read out is changed in such a manner that it is equal to the level which it would have at the time at which it would be read out without speed error. This change is achieved as a function of the speed error of each signal in combination with the level of two successive scans which are read out of the memory.

Title: Scanning device with variable scanning density
Inventor: OTSUKA HIROTAKA
IPC: H04N1/04
Filed: 1982-09-29
Abstract: In this device, an original is scanned along each of a multiplicity of parallel line paths by means of a light beam with fixed light spot size at constant speed in order to generate an image signal, and the scanning is successively shifted to the next line path in each case. The image signal is scanned is order to generate an image interrogation signal. Each line path is divided into a multiplicity of line sections in such a manner that each section results in a multiplicity of line interrogation signals, and the line paths are combined to form a multiplicity of groups of adjoining line paths so that image interrogation signals are derived from a multiplicity of patterns of lines and columns. The total value of the image interrogation signals for each pattern is arithmetically divided by the number of the signals in accordance with a control signal, in order to obtain an average value by this means.
