Title: Pulse ring for vehicle wheel with brake antilock monitoring - fills gaps between magnetic or ferromagnetic teeth with plastic magnetically-neutral brake-lining material to provide smooth outer surface
Inventor: BAUMGARTNER HANS
IPC: G01P1/00
Filed: 1992-09-08
Abstract: The pulse ring cooperates with a rotation sensor and has an annular section (2) with magnetic or ferromagnetic teeth which are scanned magnetically.

Patent DE-4237422-A1 (DE)
Inventor: MAGERL BERNHARD
IPC: B23Q3/06
Filed: 1992-11-05
Abstract: The work-clamping device has two clamping pieces (6, 7) clamping the workpiece (5) like a vice and pivotable about the axis of rotation of an adjusting device which can be indexed by angular increments. The first clamping piece (7) is fastened to the drive spindle (11) transmitting the adjusting moment (Mv) and guided in the first housing (1), while the second, freely rotatable clamping piece (6) is connected to the supporting spindle (3a, 3b) mounted in the second housing (2a, 2b). A hand-operated or motor-operated mechanism (4) transmits the clamping force (K) necessary to hold the workpiece (5) to the second clamping piece (6) and produces the axial movement of the supporting spindle (3a, 3b) required for clamping and unclamping. The clamping force (K) is essentially transmitted frictionally to the workpieces (5) and brings about their positioning during the individual machining operations and the rotation into the next machining position. The work-clamping device not only permits the machining of cylindrical workpieces (5) clamped in the axial direction; by means of clamping pieces (6, 7) of appropriate design, parts of any shape can also be machined from several sides without reclamping. With the work-clamping device, several workpieces (5) can also be machined simultaneously in one set-up on several sides in each case in an especially efficient manner. <IMAGE>

Title: Alcohol-free beer - obtd. by mixing low alcohol full beer wort prod. with diluted low alcohol ordinary beer prod.
Inventor: BARTELS HELMUT
IPC: C12G3/08
Filed: 1992-12-01
Abstract: To produce an alcohol-free beer, with an alcohol content of up to 0.5 wt.%, the initial full beer wort is mostly or wholly fermented, and the prod. has the alcohol removed to a level of up to 0.5 wt.%. A second full beer wort is diluted with water to give a wort content of an ordinary beer and then fermented to an alcohol content of up to 0.5 wt.%. The treated full beer wort is mixed with the treated ordinary beer to give an alcohol-free beer for serving. Pref. the second full beer wort is diluted to give a wort content of 3 wt.%, and then hops are added and boiled for further hops isomerism before mixing, and a colouring beer can be added ot it before mixing with the first component. During mixing, for fermentation, a reduced amt. of yeast cells per ml wort is added together with wort aeration. The mixing of the two prods. is at a ratio of 1:1. ADVANTAGE - The technique gives a high quality beer with full fermentation, increased productivity and reduced costs.

Title: Temperature measuring system for locating leaks in sewage systems
IPC: G01M3/00
Filed: 1993-03-08
Abstract: Proceeding from available waste-water supply systems, until now only monitoring of the tightness in the course of new construction and regular inspection (on foot) and television investigations with qualitative consideration of the interior of the pipes have been carried out in order to discover any damage of the sewage systems present. One solution in the case of the location of leaks of new sewage pipes to be laid is offered by an empty plastic pipe which is laid under the sewage pipes during their building-in (Figure). At any desired time, temperature measuring sensors can be guided into this empty plastic tube, by means of which temperature measuring sensors the temperature can be detected at any location under the sewage pipe. Waste water which seeps downwards under gravity from leaks in the sewage system changes the temperature field there and can thus be detected. <IMAGE>

Title: Automatically opening secondary-air opening during the burning of wood in fireplaces by using a bimetallic spring
Inventor: KAUS WILHELM
IPC: F23N5/04
Filed: 1993-09-28
Abstract: During the burning of wood in fireplaces, once the temperature is reached either the primary-air opening of the fireplace is automatically closed by a regulator, or the operator of the fireplace closes the primary-air opening by hand. In both cases, the oxygen required for combustion is withdrawn and this has a detrimental effect on the combustion (formation of smoke and tar). The automatically opening secondary-air opening prevents this. In order to provide the fireplace with the required oxyten during the burning with wood, an automatically opening secondary-air opening with a bimetallic spring is provided on the upper fire door, said opening always supplying the fuel with sufficient oxygen. The automatically opening secondary opening with a bimetallic spring is suitable for all fireplaces which are run on wood and have an upper and a lower fire door.

Patent DE-4403125-A1 (DE)
Inventor: BAENZIGER ULRICH
IPC: H01L21/3065
Filed: 1994-02-02
Abstract: The invention relates to a device for generating plasma by the inductive coupling of H.F. energy by means of a aerial. One problem of purely inductive coupling is that, owing to its finite inductance, there are potentials on the aerial which result in a capacitive component in plasma excitation. This capacitive component is undesirable as it leads to excessively high plasma potentials which have an adverse effect on substrate processing. The device of the invention is distinguished by an aerial which completely surrounds the plasma production chamber in the form of a ring, in which the two aerial leads are connected thereto at opposite points on the ring. The low inductance of this aerial results in a manifest reduction in the capacitive component of the plasma excitation in relation to prior art devices. The simple shape of the aerial makes for a compact design of the device. The main field of application of the device for plasma generation of the invention is in the plasma-supported processing of substrates in semiconductor manufacture.

Patent DE-4405556-A1 (DE)
Title: Receiver of electromagnetically generated free electric waves by electrolyte resonance
IPC: H04B1/24
Filed: 1994-02-17
Abstract: Electrolytic solutions are held in non-metallic containers of any shape. In these solutions, resonant oscillations of the ions and dipoles are induced through the free electric waves. The induced electric varying voltages induced at opposite sides of the container are fed off via electrodes (4,5). The latter are connected such that the free electric waves can enter the container (1). A controllable direct current may be conducted through the solution which aligns the ions and dipoles of the solution to increase the sensitivity of the receiver. Alternatively, a controllable direct current may be applied to electrodes which are insulated against the solution. An electric field is thus formed between the electrodes which aligns the ions and dipoles of the solution to increase the receiver sensitivity. The resonance frequency of the ions and dipoles can be tuned by varying the capacitance of a capacitor to the transmission frequency of the free electric waves. Alternatively, the frequency can be tuned by varying the inductance of an electric coil.
