Title: Comminution device and process for its production
Inventor: WYSS FRANZ J
IPC: B02C18/18
Filed: 1982-07-26
Abstract: A comminution device has at least one pair of parallel shafts which has several mutually meshing disc-like cutting blade elements (2) with spacer discs (3) lying between them. The cutting blade elements and the spacer discs are pressed together by means of the inherent elasticity of the shaft by a clamping element (5) arranged at the shaft end (4). The torque is transmitted laterally via the cutting blade elements and the spacer discs, so that only a tensile stress arises in the shaft. This results in an advantageous transmission of the forces. <IMAGE>

Title: Method and self-monitoring device for measuring and recording solids in gases
Inventor: BREIDUNG FRIEDHELM DIPL ING
IPC: G01N15/06
Filed: 1982-09-10
Abstract: In conjunction with the device, the method is used to measure and record dust concentrations in gases. It is preferably used in the emission monitoring of dust filtering plants and serves to protect the environment. Method of operation: a branch current is taken from the gas via a suction probe (7) and fed as a defined amount through a filtering fabric (4) by means of an impeller (3). In the case of gas containing dust, the dust is retained with the assistance of the gas flow upstream of the filtering fabric (4) and pressure builds up with time as a function of the dust concentration as a result of the restriction of the free filter cross section. The sensor (5) enters the values into a microprocessor (6) which compares them with the values stored in the microprocessor (6) during calibration and calculates the instantaneous dust concentration. The values are recorded using the plotter (6a). To clean the filter, the filter (4) is turned through 180 DEG  and the subsequent gas stream, assisted by compressed air and tapper, cleans the filter (4). <IMAGE>

Title: Method of producing micro-bores in the  mu m-range with the use of electrical discharge machining
Inventor: MAIER MARTIN DIPL ING
IPC: B23H9/14
Filed: 1982-09-14
Abstract: To produce micro-bores in the  mu m-range, first of all a blind hole is eroded in the workpiece in a known manner by electrical discharge machining. At the same time, unlike the previously known methods, pressure is applied to the underside of the workpiece. The actual break-through of the hole is reached when an individual spark partially melts through the remaining wall at one point at the bottom of the blind hole. Consequently, the molten metal is thrown out at this point through the already eroded part of the hole as a result of the high pressure on the underside of the workpiece, which results in the actual break-through of the hole. In order to prevent the following spark from enlarging the hole, the electrical discharge machining must be switched off directly after the hole develops. Nozzles used for the most varied purposes and which are required, for example, to produce minimum throughputs or a thin jet at high pressures are suitable as a field of application for micro-bores of this type.

Title: Common all-wheel drive for two-wheeled and similar vehicles
Inventor: WITTKOWSKY FRIEDRICH
IPC: B62M23/00
Filed: 1983-05-26
Abstract: The drive is transmitted to all wheel hub shafts from a revolution or reciprocating stroke, which is mutually nonuniform and lengthens the working phase, of the crank or by engine power via a common, multistage variable-speed transmission by means of shafts or chains in the members of the vehicle frame and wheel fork and a steering-movement differential gear. The uniform distribution thereby achieved of the better-used driving force to all road wheels improves the dynamic handling and braking performance of the vehicle, while the selectable drive by means of reciprocating stroke or crank enables higher accelerating performance when required.

Title: Automatic, gyroscopically-controlled transmission for various road and rail vehicles
Inventor: SORO LADISLAUS DIPL ING
IPC: F16H3/72
Filed: 1983-11-03
Abstract: For even, jerk-free coupling of the vehicle to the drive motor. The action of the gyroscopic clutch occurs automatically as the engine rev counter rises and the mass of the rotors can be adjusted so that locking of the clutch occurs at the optimum engine speed and this continues even in the event of subsequent reductions in the engine speed. Advantageous mainly in the avoidance of heat generation as in the case of conventional friction clutches and automatic hydraulic clutches. Instead of the action of the oil pressure or friction plates, in the gyroscopic the gyrostatic moment of the rotors is utilised and the centrifugal force of the asymmetrical rotors is used for locking the entire system. By increasing the mass of the rotors or the asymmetry of the rotors it is possible to increase the efficiency of the entire clutch as required.

Patent DE-3404667-A1 (DE)
Title: Speed limiting in carburettor engines not yet at operating temperature
Inventor: KELLNER HANS JUERGEN
IPC: F02P11/02
Filed: 1984-02-10
Abstract: The invention prevents engine damage which can occur if the still cold engine is loaded with too high an engine speed. In particular this involves the following damage:     Compression loss   High petrol consumption   Valve damage.   Since not every vehicle is equipped with an oil or water temperature display and not every car driver refers to the abovementioned displays, the maximum admissible cold engine speed can easily be exceeded. In order to remedy this situation an auxiliary unit is used which records the instantaneous oil temperature and engine speed of the engine. This information is processed in the auxiliary unit and according to the instantaneous condition switches a relay, which interrupts the ignition circuit until the admissible cold speed is reached. The circuit ensures that in the engine warm-up phase the appropriate speed is adhered to.

Patent DE-3407104-A1 (DE)
Title: Desublimator
Inventor: RUDOWSKI WERNER
IPC: B01D7/02
Filed: 1984-02-28
Abstract: The hitherto known desublimators are provided in the interior with bundles composed of finned tubes, through which a cooling or heating medium is alternately passed, in order to obtain a product contained in a gas/vapour mixture. However, in small-scale desublimators, this method of construction leads to laborious heating, to channelling and to high construction and production costs. According to the invention, instead of the finned tubes, plates 26 are now attached in the interior of the housing 1 to the housing side walls. The cooling or heating medium is only conducted via channels which are arranged on the outside of the housing side walls. The heat transfer is carried out by the channels on the housing side walls to the plates 26. The advantage of this arrangement is the use of any weldable material for the plates 26. Leaks and channelling are avoided. Steam can now be used for heating and water for cooling. Construction and production costs are low. The plates 26 can be straight and run vertically. However, zigzag-shaped or wave-shaped plates are also possible. The plates can penetrate from top to bottom or they can be provided in a plurality of rows arranged one above the other. <IMAGE>

Title: Demountable connection for optical fibres
Inventor: DOMANN GUENTER DR RER NAT
IPC: G02B6/36
Filed: 1984-03-16
Abstract: A demountable connection for monomode fibres is proposed whose connection halves contain centring elements which are constructed as a plug-in part and socket part or as a hermaphrodite plug. The centring elements consist of, e.g. silicon platelets (11, 12) which each contain a central hole (2) and a fibre end (3) fixed therein perpendicular to the plane of the platelet by means of adhesive (4). By applying photolithographic technology, the platelets (11, 12) are each provided with a plurality of centering marks which are precisely assigned to the fibre core and from which protuberances and complementary depressions (13) are produced by means of anisotropic etching. The depressions (13) can be constructed in the form of a pyramid or V-groove, and their complementary protuberances can be produced by etching or by balls (14) or needles fixed in such depressions (13). A method for producing the centring elements is specified. <IMAGE>

Title: Telescopic unit
Inventor: WALTER LOTHAR
IPC: F16C29/06
Filed: 1984-06-16
Abstract: A telescopic unit for a windscreen wiper device consists of a U-shaped inner rail (1), a U-shaped outer rail (3), and at least one support row of loaded balls (9) which roll between a groove-type inner raceway (8) of each of the two inner limbs (2) of the inner rail (1) and a groove-type outer raceway (7) of the opposite outer limb (6) of the outer rail (3). In order that the telescopic unit has a relatively large space between the inner rail (1) and the outer rail (3) despite a compact construction and, additionally, loss of lubricant during operation is avoided, each support row is closed at its two ends by an exclusive return row of non-loaded balls (10) to form an endless row of balls. This row of balls is incorporated in a guide channel (11) of a cage (12) which is firmly connected to the inner or outer rail (1, 3). The balls (10) of the return row run on a return track (13) of the inner or outer rail (1, 3) connected to the cage (12) and are tightly covered by the guide channel (11). The balls (9) of the support row are arranged in a continuous guide slot (14) of the cage (12). The cage (12) bears sealing means (15) which completely surround the edge of the guide slot (14) from the outside. <IMAGE>

Title: Process for improving the efficiency in the purification of flue gas, for example by the "scrubber principle"
Inventor: KUECKENS ALEXANDER
IPC: B01D53/60
Filed: 1984-07-06
Abstract: An improvement with regard to the efficiency in combination with reduced environmental pollution can be made possible by first recovering fertiliser or improved building materials, such as high- grade gypsum, in a known manner from flue gas wastes, in particular from SO2 and NOx, and connecting downstream of such a process a stage for CO2 liquefaction which in turn, following a special process by impregnation of irrigation water, is used in fertilisation, as a result of which an elevated yield increase is possible in all application areas with all ornamental and economic plants. At the same time, an improved nutrient uptake by the plants is possible by the novel process, as a result of which soil leaching and inputs into the ground water are reduced. Since atmospheric pressure and atmospheric gas distribution and thus also the Gay-Lussac law prevail in the top soil layers, gas exchange is promoted by supply of CO2 and thus the oxygen supply to the roots is improved and the soil is also loosened by nitrogen aeration.
