Patent DE-4415437-A1 (DE)
Title: Infinitely adjustable shelf support
Inventor: TRAGE ALEXANDER
IPC: A47B57/06
Filed: 1994-05-03
Abstract: The bar (1) is rounded and is pressed onto the two parallel friction tracks (4,4.1) by flexible ties (3). The ends of the ties are secured to the respective ends of the support board and each tie is looped around the bar. Twisting of the bar adjusts its position along the support board.

Patent DE-4417052-A1 (DE)
Title: Method for digital demodulation of frequency-modulated signals
Inventor: HENZE WERNER
IPC: H03D3/00
Filed: 1994-05-14
Abstract: In the case of the method for digital demodulation of frequency-modulated signals, the demodulation is carried out by direct measurement of instantaneous frequencies. Frequency-measurement periods are formed from the input signal by multiple mixing with phase-shifted signals. The duration of the frequency-measurement periods is measured using a plurality of phase-shifted pulse signals which are simultaneously evaluated. A high measured-value sequence (rate) and measuring accuracy are furthermore achieved by selection of the measuring-period duration, frequency multiplication and signal selection. The measured values are subsequently processed using a DSP.

Patent DE-4427795-A1 (DE)
Title: Metal-based composite material
Inventor: TAKAGI KATUMI
IPC: C22C49/04
Filed: 1994-08-05
Abstract: A metal-based composite material which includes  a metal matrix including aluminium as a main constituent,  discontinuous aluminium oxide fibres submerged in the metal matrix,  mullite particles submerged therein  and solid lubricant particles submerged therein. The solid lubricant particles may either be graphite particles with a nickel coating formed on their surface or boron nitride cermet particles. By virtue of thus embedding the special solid lubricant particles it is possible to improve the abrasion resistance of the metal-based composite material and to reduce the wear of its mating parts and to prevent any fluctuation of the coefficient of friction between the metal-based composite material and the mating parts. The metal-based composite material may therefore suitably be used for the manufacture of aluminium-based internal combustion engines.

Abstract: The purification installation with one preliminary clarification stage is intended to purify mechanically waste waters. It comprises an activation stage, with at least one activation tank, and at least one final settling stage with one or a plurality of final settling tanks. A compressed air source supplies the activation stage with compressed air.

Filed: 1988-03-03
Abstract: Closure (1) for a receptacle (3), particularly for pharmaceutical receptacles and in particular those closed by means of a stopper (4) which may be pierced by a syringe, said stopper being held by a cupular retaining capsule (5), gripping the rim of the receptacle, and itself provided with a circular part (8) covering that area of the stopper (4) which may be pierced by a syringe and detachable along a weak seam (7), preferably forming a seal with the rest of the capsule and attached by adhesive to a lid part (6) even when the latter is removed. The interior of the lid part (6) of said closure (1) is provided with a reception and guiding section for the adhesive, forming the adhesive area, in an area extending approximately from the edge of the circular part (8) across a part of the surface of said circular part, closed to the edge of the circular part (8) and open to at least some areas of the remainder of the surface. The reception and guiding section offers the advantage of forming, with its closed edge, the edge of the adhesive area which faces towards the predetermined weak seam (7), preventing adhesive area which faces towards the weak seam (7), preventing adhesive from passing through it. Even when the surface offered by the circular part (8) is only partially used, the reception and guiding section promotes a high degree of adhesion in the glue or seal joint made at this point.
