Patent DE-4113745-A1 (DE)
Inventor: MEHNERT WALTER DIPL ING DR
IPC: G01D5/20
Filed: 1991-04-26
Abstract: At least one exciting coil (6) supplied with alternating current to generate a magnetic flux. A measurement coil arrangement (8,9) contains at least two adjacent flat elements (38,39) enclosed by a measurement coil winding. A ferromagnetic flux guidance arrangement forms an annular closed path for the magnetic flux with an air gap concentrating the flux in a region which can intersect the flat elements at a transmission surface which is displaced according to the body motion. The flux passing through one element increase as that through the other decreases, so that the relative positions of the two bodies can be derived from the electrical output signals from the measurement coil arrangement. The flat elements have at least one common edge part, over which the transmission surface can be displaced.

Patent DE-4129281-A1 (DE)
Title: Powder plate granulation with automatic control - uses samples from smallest build=up  zone to set adhesion rate
Inventor: METZGER KARL-LUDWIG DR
IPC: B01J2/14
Filed: 1991-09-03
Abstract: The plate granulation process for a powdered solid, using an angled and rotating agglomerating plate to give powder trains to be sprayed with a granulation fluid, sets the rotary speed of the plate to 50-60% of the critical rotary speed. Particle samples are taken continuously or at intervals from the smallest build up zone within the test bed for the distribution of the particle size to be measured. The adhesion rate in the solid matter on the plate is reduced if the mean grain size of the particles is smaller than a nominal value, and increased if the mean grain size expands. Pref. the moisture level of the bed of vibrated matter (3) is measured without contact at the ejection zone to adjust the feed (2) or powder flow to maintain a constant rate, using an infra-red remission photometer. The adhesion rate is adjusted by setting the delivery point for the granulating fluid where the solid matter vibrates, and by altering the action of at least two spray jets where at least one is directed at the powder structures and the other is aligned at the vibrating solid matter, and by varying the external feed of an adhesive medium. The particle size distribution is measured with a lateral flow viewer. The adhesion rate is altered under-proportionally on small deviations of particle size form a nominal value, and over proportionally on large deviations. ADVANTAGE - The technique gives an automatic control of the granulating operation.

Title: Device for keeping drinks fresh until container is emptied - comprises inflatable bag slowly inflated by incoming air as drink is removed
Inventor: DUERR KARL
IPC: B65D81/24
Filed: 1991-10-29
Abstract: The drink, e.g. wine, is stored in a container, e.g. barrel, and a bag is fixed at the top of the container so that air can only pass over an opening in the lid into the bag and not past the wine. If the wine is now emptied from the bottom of the container, a vacuum arises which draws the air through the opejning in the lid and inflates the bag, so that this always adjoins the surface of the wine until the container is emptied. USE - The wine remains fresh to the last litre.

Patent DE-4211249-A1 (DE)
Title: Pulling tight hoisting cable of grab crane - using reduced torque from hoisting drive during grabbing process which is sufficient just to pull cable tight
Inventor: AXMANN ARNOLD DIPL ING
IPC: B66C13/10
Filed: 1992-04-03
Abstract: The procedure for pulling tight the hoisting cable of a grab crane is performed with a frequency converter drive but without speed monitoring of the hoisting drive. For low speeds, the drive motors use open-loop control rather than closed-loop control. During the grabbing process, the crane control device for the hoisting drive assumes a certain frequency set point and reduces the current for the drive to a lower value than normal. This value is chosen so that the hoisting torque is sufficient to pull the cable tight without interfering with the grabbing process. The assumed frequency set point lies below the frequency threshold at which the frequency converter switches from open-loop to closed-loop control. ADVANTAGE - Ensures that correct tension is applied to hoisting cable so that grab bucket collects full load of material.

Patent DE-4225245-A1 (DE)
Inventor: BAST JUERGEN DR ING
IPC: B22C9/04
Filed: 1992-07-30
Abstract: In the full-mould casting method, lost patterns (generally composed of rigid polystyrene foam) are embedded in a binder-free free-flowing moulding material (e.g. silica sand). One difficulty with this method is filling critical parts of the pattern, such as undercuts and dome-like cavities, with the moulding material in such a way that the said moulding material surrounds even these parts of the pattern without gaps. According to the invention, the moulding material has beat frequency oscillations imparted to it during its entry into the mould box. The beat frequency oscillations are generated from two fundamentals of the same or almost the same amplitude which have a variable, slightly different fundamental frequency and/or fundamental phase. The beat frequency oscillations can act on the mould box in the horizontal and/or vertical direction. In this way it is possible to embed patterns with extremely critical parts in a manner which meets quality requirements. <IMAGE>
