Patent DE-3706847-A1 (DE)
Title: Technique and device for inductively monitoring moving machine components for wear and fracture
Inventor: NORDMANN KLAUS DIPL ING
IPC: G01N27/72
Filed: 1987-03-03
Abstract: In a technique and device for monitoring moving machine components, in particular tools, for wear and fracture, a plurality of monitoring methods are carried out using only one coil. The methods mutually check the information they provide on the state of wear and fracture in the machine components. The magnetoelasticity, the temperature dependence of the permeability and the shape permeability of the ferromagnetic machine component materials are utilised in these methods. The magnetoelasticity makes it possible to measure with one coil the wear-dependent structure-borne sound and mechanical stresses, for example, on the tool itself, and also the change in the mass-dependent and geometry-dependent natural frequencies due to fracture. Using a special version of the pulse-echo technique, the tool can be monitored for fracture with the same coil. The temperature dependence of the permeability serves to monitor temperature rises due to wear. The shape permeability is used to monitor moving machine components such as tools for shortening due to fracture. The flat, annular coil measuring only a few millimetres generally surrounds the machine component to be monitored concentrically.

Title: Control device for preventing the locking up of a wheel of a vehicle during braking
Inventor: KINDLER ADOLF DIPL ING
IPC: B60T8/52
Filed: 1987-06-16
Abstract: If, in accordance with the adhesion coefficient/slip diagram, the respective magnitude of the effective braking torque between the wheel and the road, which corresponds to the respective adhesion figure, is used as the controlled variable, it is necessary, if using a movable brake caliper supported, for example, against a spring accepting the braking torque or against a relevant part to record the change in length, the so-called spring deflection, which occurs under the influence of the respective braking torque, which manifests itself in the supporting force, and to enter this value as the controlled variable into the control system.
Patent DE-3721654-A1 (DE)
Title: Method and apparatus for the production of, in particular siphon cups
Inventor: SCHULTE HUBERT
IPC: B21D22/02
Filed: 1987-07-01
Abstract: The invention is concerned with a method and an apparatus for the production of pots, cans or the like, especially for the production of siphon cups with an integrally formed screw thread on the outer edge in the region of the opening of the cup, the aim being that the solution should open up the possibility of being able to design objects hitherto produced as castings as deep-drawn pants. In terms of method, this is achieved by the production of a preform by multi-stage deep-drawing, followed by the formation of an encircling outward-pointing bead in the region of the upper edge of the preform by means of an expansion tool and, in a further step, rolling of a thread onto this outer bead. <IMAGE>
Patent DE-3728329-A1 (DE)
Title: Resistance welding method, especially a spot-welding method
Inventor: MATUSCHEK ULRICH DR RER NAT
IPC: B23K11/10
Filed: 1987-08-25
Abstract: In the case of resistance-welding methods, especially spot-welding methods, energy is supplied in a metered manner to the electrodes by changing the phase gating angle of the mains AC voltage or by emitting welding-current pulses, and the electrode voltage is measured continuously. It has been found that defective contact between the electrodes and the workpiece can be determined by measuring the electrode voltage during the phase-gating pauses. In order to avoid disturbances resulting from this defective contact - if the electrode voltage exceeds an adjustable threshold, for example 10 millivolts, during a phase-gating pause - the power supply for the next half-cycle is reduced to such an extent that splashes or so-called bangs do not occur.

Inventor: KURZ ARTHUR
IPC: G11B7/095
Filed: 1987-09-30
Abstract: Apparatus for the reproduction of data, which can be read contactlessly from a recording medium by means of an optical pick-up device. 
<??>Such apparatuses are equipped with a focus control circuit, in order to focus the light beam picking up the data onto the recording medium, and with a tracking control circuit, in order to be able to guide the light beam on the data tracks. The light beam is reflected from the recording medium onto a photodetector (PD) comprising a plurality of photodiodes (E, F). Because actual photodiodes (E, F) are not completely identical, they give off different photoelectric voltages under the same illumination. Therefore, the control amplifier (TR) of the tracking control circuit operates unsymmetrically. 
<??>In order to bring the operating point of the control amplifier (TR) of the tracking control circuit into the optimum centre position, an offset-compensation voltage is applied to an input of the control amplifier (TR) and varied until the photoelectric voltages of the photodiodes (E, F) from which the track error signal (TE) is obtained are of equal magnitude.

Patent DE-3735636-A1 (DE)
Inventor: SCHWEINFURTH HERMANN DIPL ING
IPC: B01D11/02
Filed: 1987-10-21
Abstract: During decaffeination of green coffee, the green coffee beans swell to about double their volume. To prevent blockage, coffee beans are therefore kept moving during the pre-swelling, but this leads to detachment, from the surface of the beans, of fine particles, which then clog an adsorber for caffeine adsorption. It is proposed that, at least in the first treatment step, a container is used whose side walls run at least substantially at an angle to each other, forming a conical container space.

Title: Method for the production of built-up crankshafts by expansion of the pins
Inventor: MAUS WOLFGANG
IPC: F16C3/10
Filed: 1987-11-05
Abstract: Separately produced crank webs (1) and bearing pins (2) are connected to one another by plastic expansion of the latter, the former being subjected to stress only in the elastic range. Bearing bushes (4) composed of a material which is particularly suitable for this purpose (e.g. lubricant-impregnated sintered material), sliding (6) or rolling bearings (7) and undivided connecting rods (5) are mounted on the bearing pins (2) even before assembly and, as a result, the connecting rods are easier to install and they can be of lighter-weight design and aligned more accurately. In addition to lower weight, more economical manufacture and a longer service life are achieved. <IMAGE>
