Title: Light brick of clay, loam or the like and process for its production
Inventor: TROST PETER
IPC: E04B2/02
Filed: 1982-03-23
Abstract: A process for producing a light brick and a corresponding light brick which is produced from clay or loam are described. In the case of the novel process, the brick material is forced out of a mouthpiece to the brick mould, having a plurality of mutually parallel running perforations, is cut off to brick length and subsequently dried and fired. What is novel is that, when forcing out from the mouthpiece, chambers aligned parallel to the longitudinal side of the brick are cut out, but the cut-off cores remain in the chambers until the brick has been fired and only then are drawn out. These chambers can subsequently be filled with cork inserts. The advantage of the novel process is that the brick can be treated like a brick of the known type both during drying and during subsequent firing, but subsequently nevertheless additional chambers have been formed, which can be filled with insulating elements.

Title: Method and device for detecting the electric charge of particles existing in a gas flow
Inventor: BUCSKY GYOERGY DR
IPC: G01R29/24
Filed: 1982-03-25
Abstract: The invention relates to a method and a device for detecting charges of particles existing in a gas flow, in which, for determining the concentration and flow parameters of the flow system, the quantity of charge extracted for the determination is returned to the system after the measurement has been taken. This stabilises the space charge in the vicinity of the detection electrode and increases the accuracy of the measurement results. The solution according to the invention can be used for detecting the electric charge of grainy goods, powders or other matter particles conveyed in a gas flow in a closed system. The charge of the particles is produced by the action of the impacts and driving occurring between them or in another natural way and can also be artificially generated.
Patent DE-3211339-A1 (DE)
Title: Solar installation
Inventor: KREISSL OTTMAR DIPL ING
IPC: F24S23/00
Filed: 1982-03-27
Abstract: The use of light guides for the purpose of energy transport in solar installations with concentrating reflectors and (Fresnel) lenses (10-12) is described. The radiant energy concentrated in the respective focal plane is coupled in each case into one or more receptor cones (15a-17a), relayed to one or more light guides (15-17) and guided in the light guide by means of multiple total reflection to an energy transducer (13) whose installation site can thereby be selected independently of the location of the reflector or lens system. The beam exit end (25) of the light guides is directed perpendicular to an irradiation plane (26) of the energy transducer and is arranged at a selectable distance from the irradiation surface (26). The result is that the highly concentrated radiation which emerges from the respective guide is distributed over a relatively large area in order to avoid problems with materials in the energy transducer. <IMAGE>

Patent DE-3219104-A1 (DE)
Title: Apparatus for charging components
Inventor: JANICSEK FERENC
IPC: B65G11/00
Filed: 1982-05-18
Abstract: The invention relates to an apparatus for charging components which are intended to be discharged predominantly individually. The operating method of the charging apparatus is essentially based on the principle of communication vessels and exploits the phenomenon where, in the interior of a tube, the components arranged one above the other move in the branches of the tube in the same way as a liquid, assuming that the outline of the components corresponds to the internal cross-section of the tube and the inner volume is filled and vibration is provided. The essence of the invention is the use of a vibrated U-shaped communication tube, whose branches are of different heights. The components are introduced in a columnar manner into the higher branch and are then raised up, in the manner of a liquid, in the lower branch of the tube, from where they can be removed individually by vacuum removers and can be positioned at any location, e.g. in the interior of a pressing machine. <IMAGE>
Patent DE-3230440-A1 (DE)
Title: Device for replenishing the oil in the sump of an engine
Inventor: RATHJEN KARL-HEINZ
IPC: F01M11/06
Filed: 1982-08-16
Abstract: The invention guarantees that, when the oil level in the sump of an engine falls, additional oil flows automatically out of an oil reservoir and the flow of additional oil is stopped when a certain oil level in the sump is reached. For this purpose, the oil sump is connected via a gravity oil-feed line to the oil reservoir and the gravity oil-feed line is closed by a float valve arranged at a fixed level in the sump. One or more outlet openings closable by the float valve are arranged in the wall of the gravity oil-feed line. By virtue of the design according to the invention, the owner or driver of the vehicle is relieved of the task of checking the engine oil level manually. All that has to be checked is whether there is still sufficient oil in the oil reservoir. To facilitate this check, the oil reservoir is composed of a transparent material.

Patent DE-3234131-A1 (DE)
Title: Device for illumination of stages and other presentation spaces with light of changing colour
Inventor: OHLENDORF HEINZ-CHRISTIAN
IPC: H05B37/02
Filed: 1982-09-15
Abstract: A number of light sources, such as spotlights, lamps or groups of lamps of different colour can be varied with regard to their brightness. Control of the brightness of the light sources takes place by means of at least two variable resistors, the adjustment directions of which are perpendicular to one another, by means of an adjustment member, e.g. a joystick, which is displaceable or swivellable in an area. The area, within which the adjustment member is movable, is assigned a colour triangle or a colour circle in such a manner that a definite colour of the illumination device corresponds to each point of the area. By means of additional adjustability of the adjustment member, e.g. by means of a rotation or a displacement perpendicularly to the area, the colour saturation for all colours can be varied. A second manner of adjustability of the adjustment member can serve for regulation of the brightness of an additional white light source. Variation of the colour saturation takes place by means of concentration of the characteristics on a part of the path of the adjustment device. Circuits for control of the colour setting and the colour saturation are indicated.

Patent DE-3330473-A1 (DE)
Title: Non-contact seal
Inventor: PRIBNOW HANS-HERMANN DIPL ING
IPC: F16J15/447
Filed: 1983-08-24
Abstract: In order to seal a stationery machine part (9, 10) off from a machine part, for example a shaft (8), rotatable in relation to this, a centrifugal seal and a labyrinth gap seal are combined to form a seal combination. In the centrifugal seal, centrifugal washer (2.1) and collecting chamber (3) are so matched to one another in their shape and position that when the shaft (8) rotates a virtually complete sealing effect exists. To this end, a drip collar (9.3) is attached to the inner annular duct (5) of the collecting chamber (3) on the bearing side, which collar is axially overlapped in the direction remote from the bearing by the splash edge (2.4) of the centrifugal washer (2.1). The labyrinth gap seal is fully integrated into the centrifugal seal and its annular seal gaps (11, 12, 13, 14), whether radial, axial or at an angle to the axis of the shaft (8.1), are formed as parts of the centrifugal seal. Without requiring any additional space, the bearing (1) can thus be protected by labyrinth gap seals against dust, moisture and lubricating oil losses. The seal according to the invention functions entirely without contact and wear, which simplifies servicing and maintenance and increases the service life especially at high rotation speeds and temperatures. <IMAGE>
