Title: Anchor with universal joint for roof or wall of combustion chamber - allowing rapid easy fixing of blocks during assembly utilising opposed wedge arrangement
Inventor: FLEISCHMANN WERNER
IPC: F27D1/14
Filed: 1975-07-24
Abstract: Anchoring device for anchoring roof or wall of firing chamber to a support comprises a threaded bolt which is connected cardanically to the support and which is screwed longitudinally adjustably into the tapered end of an anchor block (1a) which fits in a recess formed by the adjacent roof or wall blocks. The anchor block is in the form of a polygonal truncated prism, and the bolt forms over its free length a polygonal spanner-engaging surface and includes on the support side a head with a bearing cup, fitting with radial play of its shank into the slotted channel-like surface of the support. In the anchor block at the level of its internal thread (2) are formed at least one pair of diagonally opposed wedges (12) which diverge towards the tapered end of the anchor block, ending flush with the block, and of which the vertical projection lies within the contours (15) of the block.

Title: Roller for pressing seed and fertilizer into furrows - consists of cover piece on outside of which protrudes first and second compacting ring
Inventor: DREYER HEINZ DIPL ING DR
IPC: A01C5/06
Filed: 1975-08-09
Abstract: The compression roller consists of a core-piece (1) to which are fixed two compacting-rings (2, 3). The compactingrings have a combined width less that of the core-piece (1) so that a surface (4) on each side of the compacting-rings runs along the soil. Between the two compacting-rings (2, 3) is a groove (5). The soil beneath the outside walls (7) of the compacting-rings which slant towards each other, is pressed down. The soil is most compacted beneath the contact surfacs (8). The groove (5) between the two rings (2, 3) produces dam (9) of soil, which prevents seed or fertiliser moving from the one furrow under the first ring (2) to the furrow compacted by the second ring (3).

Title: Data exchange between central and peripheral functional units - involves transmitter system connected to central unit through data distributor and collector unit
Inventor: KARL OTTO
IPC: H04L12/52
Filed: 1975-08-29
Abstract: The peripheral units receive data from the central unit through the distributor, and deliver to it data through the collector unit. The address of a peripheral unit (DE) is tested for correctness. It activates the data distributor (Dem) and the data collector unit (Mux) for its selection, and is supplied to address registers (AAR, EAR). Data are restored in the central unit (ZE) buffer register (IPAP) simultaneously with their transmission from this register to the selected decentral unit (DE) signal register (PIR). At the end of data transmission the central unit compares the content of the peripheral unit (DE) signal register (PIR) with that of its buffer store (IPAP).

Title: Automatic internal pressure control for gas tight spaces - by four-contact manometer actuating protective gas circuit solenoid valves, used in handling radioactive and toxic materials
Inventor: KOETHER MANFRED ING GRAD
IPC: G21F7/04
Filed: 1976-12-09
Abstract: The internal pressure of the protective gas in gastight spaces, e.g. of glove boxes for handling radioactive or toxic materials, is controlled by a gauge with four switch contacts, set at different pressures. A solenoid valve is arranged in the gas supply and another in a bypass of a restrictor to limit the exhausted gas flow; these valves are linked to the switch contacts and to a panel for display and control. If the minimum or maximum pressure thresholds are exceeded by operational activities (insertion or extraction of gloves), these fluctuations are disregarded. Mistaken interruptions of the gas supply and downtimes are thereby eliminated.

Abstract: The temperature measuring device, is partic. for central heating systems. A pair of temperature dependent resistors are clamped to the flow and return pipes of a heating system. Constant current sources supply current to the resistors, and the voltage developed across them is fed to one input of two comparator circuits. The other input of the comparators is connected to a sawtooth generator which is, in turn, controlled by a flow meter and switch arrangement. the sawtooth generator also controls a clock pulse generator. The outputs of the comparators and the clock pulse generator arefed to an AND gate and thence to a display device. The output frequency of the clock pulse generator varies linearly with variation of the measuring resistors.

Title: Pulse generator for stroboscope - uses object itself to produce pulses that trigger circuit through electrical contacts or by optical effects
Inventor: BECKER HANS-DIETER
IPC: H05B41/34

Abstract: The pulse generator, for a stroboscope, generates identical pulse trains by using the object being observed to produce the pulse trains to trigger the stroboscope. The pulse trains are produced by contacts operated by the object or by voltage or light pulses originating from the object. The total duration of the pulse train and the time between pulses can be adjusted. The control unit has two potentiometers (R5, R7) used as external controls, one for the pulse length and one for the timing interval.

Title: Centrifuge for aerosol particle spectrometers - has recirculated filtered air in chamber with fixed impeller
Inventor: HOCHRAINER DIETER DR
IPC: G01N15/04
Filed: 1977-04-22
Abstract: The aerosol spectrometer for the measurement of the aero-dynamic dia. of aerosol particles uses a centrifuge rotor having a spiral channel into which the air containing the particles is introduced. The centrifuge has a fixed impeller (16) attached to a central hub (13). The enclosed rotor housing containing the spiral channels, rotates about this hub. A boring (19) through the hub allows surplus amounts of aerosol to be sucked out. To limit the flow, an interchangeable jet (15) can be fitted at the outlet of the channel. The throughout and resolution will then be determined by the rotational speed of the centrifuge. A filter may be placed at the end of the canal so that the recirculated air is free of small particles which were not previously deposited. The circuit is a closed one which enables the air to be measured accurately and replaced by an equal amount of aerosol on a continuous basis.
