Title: Switching control for automatic camera - uses coupled transistors and switching stages replacing mechanical switch for reliability
Inventor: JEHMLICH HANS DR
IPC: G03B7/083
Filed: 1977-02-21
Abstract: The exposure control has the photocell coupled to two transistors (1, 2) with base and collectors shorted. Their outputs are taken to a switching stage (7) via a third transistor (10). The transistors are connected to the battery supply. The system eliminates any mechanical switching with its inherent unreliability. It provides an indication of the preferred exposure settings or operates exposure limit indicators. The second transistor (2) is connected to a timing capacitor (6) and to the input of a switching stage (7). The output of the latter (7) is coupled to an electro-magnet (8) ending the exposure. The transistor (10) compensates for the base to emitter potential of the first transistor (1).

Title: HF transmission cable with interference at regular intervals - introduces deviations from average distance between points as periodic function of spacer geometry
Inventor: ERDEL KARLHEINZ DIPL ING
IPC: H01P3/00
Filed: 1977-05-05
Abstract: In the hf transmission cable, the interference occurs at regular distances caused by the spacer discs along the length of the cable. The regularity of the interference produces reflections which are additive. The coaxial cable is designed so as to introduce a deviation from the average distance between the interference points. The deviation is a periodic function of a given amplitude. The multiple integral of the function among the coordinates has an upper limit. The periodicity is equivalent to that of a triangular function, or a rectangular function or a trapezoidal function, the period of which corresponds to that of the distance between the spacers.

Title: Distributed fire alarm network with centralised control - subjects incoming signals to repeated threshold comparative test and uses logic circuits prior to alarm activation
Inventor: SCHIERAU KLAUS DIPL ING
IPC: G08B25/14
Filed: 1977-05-17
Abstract: The distributed fire alarm network uses a number of multiplexed two line cables each serving an array of one or more parallel transducers, with a centralised control network in which the incoming transducer signals are subjected to a repeated threshold comparison test before a fire alarm is raised.

Title: Data reception protection in automatically controlled vehicles - involves comparing test telegram known to computer with telegram at output of series to parallel converter
Inventor: MAATJE HENRI DIPL ING
IPC: B61L27/04
Filed: 1977-06-15
Abstract: The vehicles receive data telegrams in series form from a fixed control station. At least one computer with a series-parallel converter at its input is provided for processing the telegrams. A circuit part (SL), e.g. a store, delivers a special test telegram known to the computor(s) (R). Switching circuits (S, OG2) block the series-parallel convertor (S/P) input for external telegrams, for a specified period immediately after reception of a data telegram, and connects the input to the circuit part (SL). The test telegram is then fed into the series-parallel convertor, and at least one of the computers collects the test telegram, or individual data words from it compares it with the test telegram known to the computers and delivers an error signal when they do not coincide.

Title: Serial printer type head - has variable thickness type fingers with set spacing from hammer to avoid ribbon damage
Inventor: MANDEL WALTER DIPL ING
IPC: B41J9/26
Filed: 1978-06-24
Abstract: The serial printer employing type element fingers simplifies the control of hammer impact force to match the length of the imprint character. This avoids damage to ribbon and to document if the same force is applied when printing such characters as M or a comma. Instead of complex electronic control varying the impact force for each character, the type fingers are made of different thickness to maintain a constant spacing between the impact surface of the type finger and the hammer. The printing hammer (2) operates then with a constant force against the type elements (3) of the printing head. The imprint force controlling factor is included in the elements (3) by leaving the impacted side at a constant distance from the printing plane.
