Patent DE-2436342-A1 (DE)
Inventor: MEIBES HELMUT
IPC: F16L3/22
Filed: 1974-07-27
Abstract: The heating installation for supplying a number of homes comprises one primary and at least one secondary circuit. The primary circuit (10) arranged outside the homes consists of a heat generator, a forward run line (10a) and a return run line (10b). The secondary circuits (11) starting from the primary circuit (10) are laid in the home and consist of only one circuit loop with connected radiators (12). The radiator connection valves make it possible for the water to flow past when the radiators (12) are shut off. The mounting sequence of the heating installation can be arranged in a form which progresses from home to home. Irrespective of the position of the radiator valves, constant operating pressures are ensured. <IMAGE>

Title: Information conversion and retrieval system - utilises cine film record of binary coded data as input to logic cct. controlling projector
Inventor: BALASCHOW WLADIMIR NIKOLAJEWIT
IPC: G06K17/00
Filed: 1974-08-21
Abstract: The data search system makes use of a cinematograph film for storage cells (130, 131) for light or dark areas representing a data code and is associated with picture images on a corresponding film (132, 133). Recognition of the code enables the correct film image to be projected as in a teaching machine or micro-fiche viewer. The data processing circuit includes a data store for each film, a selector, a code converter and a control unit. The latter employs a logic circuit with AND and OR gate elements to manipulate the binary codes. Information from the control film is collected by a photocell scanner for conversion to electronic pulses, and is passed to a coincidence network before operating the selector and storage address units.

Title: Receiver basic sensitivity switching circuit - uses for switching directional voltages derived from receiver discriminators
Inventor: BERTSCH HERMANN DIPL ING
IPC: H03G3/20
Filed: 1974-11-04
Abstract: The basic sensitivity of receivers is switched over by a device which reduces the gain of the receiver during tuning. The direction voltages (UR1) which can be derived from the discriminator (2) of the receiver on either side of the zero crossing of its discrimination curve, are used as switching voltages inducing a first switching state of a bistable switching stage (4). A further directional voltage, derived from the intermediate frequency and related to its mean frequency, is field strength dependent and forms a switching voltage (U2) for inducing a second switching state of the bistable switching stage. During its first state the switching stage supplies to the receiver amplifier stage (3) a switching signal (S) which reduces the receiver gain.

Title: AC logic circuit with separate input transformers - uses transistor blocking generators and capacitor
Inventor: LOTZ ALFRED ING GRAD
IPC: H03K19/007
Filed: 1975-08-29
Abstract: Input signals are applied to separate input transformers and they are rectified in their secondary circuits. The rectified input signals form individual control potentials for transistors blocking generators with feed-back transformers. The pulse voltage from the blocking generators is applied to the output through an amplifier stage in the feed-back transformer secondary circuit as in 1933713. Input signals are simultaneously applied to a second circuit with a blocking generator modified into a timing element, so that the modified blocking generator maintains damping oscillations generated by discharge of a capacitor and maintained by the capacitor control potential. These oscillations start after the end of the input signal, and are applied after amplification and rectification to the first circuit as a further control potential.
