Title: Circular saw with electromagnetic brake - has sprung armature plate attracted away from brake lining by winding when current is supplied to drive motor
Inventor: BUBEK VOLKER
IPC: B27B5/38
Filed: 1978-07-26
Abstract: The saw blade (16) mounting has a backplate (9) fitted with brake lining (13). The backplate has a hub-like extension (8) keyed onto the shaft, the extension carrying a spring (7).

Title: Solids-liquid contactor - where blocking of the annular passage between the disc edges and the drum is prevented
Inventor: HOHLBAUM THEODOR JOSEF MARIA
IPC: B01D11/02
Filed: 1978-11-17
Abstract: The contactor consists of a drum through which a slurry phase and a treatment liquid phase pass. There is a rotor in the drum including a number of axially spaced discs dividing the drum interior into a series of compartments. The edges of the discs are spaced from the drum wall to form an annular passage for the movement of the phases from compartment to compartment. A number of receptacles are mounted to rotate with the rotor and are designed to receive material of one phase and slower it into the other as the rotor turns. The rotor also carries blades which penetrate into the annular passage and which operate to maintain the passage at least partly clear of stationary solids. The invention provides a contactor design in which blocking or partial blocking of the annular passage between the disc edges and the drum is prevented.
Patent DE-2851903-A1 (DE)
Title: Test circuit for time demultiplexer - compares test words in memory with same test words passed via demultiplexer to address memory
Inventor: BINZ REINER DIPL ING
IPC: H04J3/14
Filed: 1978-11-30
Abstract: The test circuit has the n outputs (al-an) of the address-controlled time demultiplexer (DEM) connected to the n inputs of a test memory (D, Sp). The demultiplexer's address input receives test words which are also stored in the memory's storage cells (Z1 etc). The test words are their own addresses in the memory. Initially the demultiplexer's signal input receives a 'l' signal. The test word stored in the memory at the selected cell is compared with the test word applied to the demultiplexer as address. If the two words are not the same an error signal is released indicating that the demultiplexer is not distributing its signals correctly.

Title: Pilot controlled repeater for analogue transmission system - automatically compensates for changes in analogue signal level
Inventor: POWELL WILLIAM HUGH
IPC: H04B3/12
Filed: 1979-04-04
Abstract: A repeater (1) amplifiers a range of analogue signals and a pilot signal. A filter (2) passes the pilot signal through an amplifier (3), and a rectifier (4), to one input of a differential amplifier (5). Feedback from the output of the differential amplifier is through a resistor (6) back to its second input. The feedback voltage (V1) is also a function of a fixed reference voltage (Vref). The circuit can automatically compensate for changes in the repeater input signal due to temperature changes in the cable. An alternative version has feedback from the comparator output to the pilot signal amplifier.

Title: Pneumatic bulk delivery system feed force measurement - using uncoated gas throughput and loaded gas pressure drop measurements with results stored in computer to regulate gas throughput
Inventor: NEBHUTH KARL-HEINZ
IPC: G01F1/74
Filed: 1979-06-25
Abstract: The system for measuring the force of delivery in a pneumatic delivery system in which bulk material is fed into a gas flow in a tube enables accurate results to be obtained without expensive instrumentation. They are particularly applicable to powdered and finely granulated material. The throughput of gas in the unloaded condition prior to injection of material is measured. The pressure drop in the load gas is also measured for a given section of tube. Values characteristic of the delivery force are derived from the measured values, stored, and compared with subsequently measured values in a computer. The computer performs interpolation between a small number of characteristic points to determine the force from measured values. The calculated force is then used to regulate material and/or gas throughput.
Patent DE-2926610-A1 (DE)
Title: Water and ice storage basin for heat pumps - is combined with solar heat collectors for use as heat input energy handling system
Inventor: SCHWARZ KARL
IPC: F25B30/06
Filed: 1979-07-02
Abstract: A heat pump system uses a storage basin for the input heat energy at a low-temp. level and transforms this energy for delivery at a higher temp. level. The preferred basin is a pool of water with walls, surface and reinforcement so designed that the contents can freeze without damaging the basin. A heat exchanger system on the basin bottom or inserted in it permits a transfer of the heat, developed by the water temp. dropping from 20 deg.C to 0 deg.C and by its conversion to ice, to the cold side of a heat pump. This system requires only a small area for storing a large amount of energy. In summer when the extracted energy is restored by solar radiation, the area can be used as a swimming pool. The efficiency of this system can be increased still further if solar heat collectors are used to transfer all surplus energy into this storage basin and if the heat exchanger system of the heat pump is also used for the input of solar energy. The basin is pref. covered by a transparent foil to reduce losses by evaporation and convection; in winter this could be replaced by an opaque reflective cover to eliminate, in addition, radiation losses.
Patent DE-2928477-A1 (DE)
Inventor: HUGEMANN BERNHARD
IPC: A61D7/00
Filed: 1979-07-14
Abstract: A device for the release of a substance at a defined or desired location in the alimentary tract. The device has a capsule having a separating wall therein, which forms a first chamber and a second chamber in the capsule. A hole is present in the wall of the first chamber. A compression spring, that is in a compressed state, is affixed to a body located in the second chamber. A needle is mounted on the compression spring facing the separation wall. A resonant circuit, in the second chamber, is tuned to an electromagnetic field of high frequency. The resonant circuit has a coupling coil, positioned around the body, a capacitor, connected to the other end of the coil and extending away from the first chamber, and a resistance wire, attached to the coupling coil and the capacitor. A fuse wire is connected to the compression spring, extends through the longitudinal passageway of the body and is connected to the body end facing away from the first chamber. The fuse wire contacts the resistance wire. A balloon in the expanded state is positioned in the first chamber. When the device is subjected to an external electromagnetic field having the high frequency to which the resonant circuit is tuned, the fuse wire heats up and breaks. The compressed spring is released pushing the point of the needle through the separating wall and the balloon, which bursts releasing any substance contained in the first chamber.
