Title: Transfer rollers for stack of film sheets - allows stack to sag through at centre section by having centre support roller slightly lower than outer two
Inventor: WEBER JOHANN
IPC: G03D13/00
Filed: 1979-02-21
Abstract: A stack (4) of sensitive sheets for processing is placed on top of three parallel and horizontal transfer rollers (5, 6, 7) The lowest sheet of the stack is moved sideways by the friction of the rotating transfer rollers, until it is picked up by the neighbouring set of drive rollers (8a, 8b). The middle one (6) of the horizontal transfer rollers is located slightly below the level of the outer two rollers (5, 7). This allows the stack (4) of flat sheets to deflect downwards in the middle section. In this way, the friction acting on the sensitive coat of the sheets is less likely to cause damage.

IPC: H03M1/00
Filed: 1979-03-31
Abstract: The A-D converter is designed to have a high speed of operation and is self-correcting. The system uses a test signal produced from a correction value derived from a comparison of actual and desired values. The analogue input signal is sampled by a first circuit and is A-D converted in a fast main converter. The analogue input signal is used from time to time as a system internal test signal and is fed in parallel to the main A-D converter to a sample store circuit. The signal is sampled and fed to a reference A-D converter which operates slowly and with great accuracy. The sampled signals are stored in a second store. The sampling times are synchronised and lie in a given relationship to each other. The signals fed to the first A-D converter are stored to serve as actual value signals for comparison with signals from the second A-D converter.

Title: Auxiliary transmitter for mobile radio telephone - has facility to store number in vehicle for automatic transmission via main mobile station
Inventor: JAEGER ALOIS DIPL ING
IPC: H04W68/00
Filed: 1979-09-18
Abstract: In order to cut down duty time of mobile radio telephone channels due to repeated and frustrated attempts by calling subscribers to make contact, an auxiliary radio station is used and, in the vehicles, a low power receiver which may be kept switched on all the time. This auxiliary radio station may in fact be one of the broadcast stations in current use. If a called vehicle fails to send out its confirmation signal, the second radio station would broadcast a digital signal in a form not producing an acoustic output, containing the called vehicles number followed by the calling subscriber's number. These numbers would be responded to in a storage unit of the called vehicle by loading in it the calling number, and by lighting a lamp. When the vehicle owner returns he may actuate a switch causing the stored number to be automatically transmitted via the main mobile radio station whereby the telephone subscriber concerned is called. Several such calls may then be made in the sequence the respective numbers had been deposited in the named storage register.
