Patent DE-3615060-A1 (DE)
Title: High-resolution waveguide or cavity resonator attenuation measurement transmitter
Inventor: FLIER GUSTAV DIPL PHYS
IPC: G01B7/02
Filed: 1986-05-03
Abstract: The principle of measurement that the attenuation of a waveguide or cavity resonator which is operated close to its cut-off frequency fg varies highly responsively on a steep characteristic due to changes in length of the wide side determining for the waveguide or cavity resonator attenuation, allows its application to high-resolution measurement transmitters in which all measurement quantities which are attributable to a change in length can be measured by transferring the changes in length to the wide sides influencing the attenuation. A contactless attenuation measurement transmitter is described and an elongated attenuation measurement transmitter which is not loaded by the measuring force to be applied, that is to say not subjected to measurement-force-related bending.

Patent DE-3718403-A1 (DE)
Title: Control element which can be positioned between two end positions, with an actuating element
Inventor: GREIM GERHARD
IPC: B60H1/00
Filed: 1987-06-02
Abstract: A flap which can be positioned between two end stops is frictionally connected to a lever arm which actuates said flap and on which a Bowden cable acts. For automatic adjustment between the Bowden cable and flap, the lever arm is first of all rotated with respect to the flap towards the pressure end-position of the Bowden cable. If the Bowden cable is suspended from the lever arm and then brought into its tension end-position, the flap first of all strikes against the stop in its end position; a further actuation of the Bowden cable finally rotates the lever arm with respect to the flap to such an extent that the end positions of Bowden cable and flap correspond. The frictional connection may be designed as a press fit or be implemented by means of a spring element.

Title: Piston ring for internal combustion engines
Inventor: JAKOBS ROLF DR
IPC: F16J9/02
Filed: 1988-03-03
Abstract: In the fitted state, known oil scraper rings twist positively. This results in a worn ring nose edge which adversely affects the oil consumption of the internal combustion engine. The new oil scraper ring is intended to ensure an oil scraper effect over a long operating time. The oil scraper ring (1) fulfils this requirement in that a cross-sectional obstruction (4, 10, 10') is arranged on the side remote from the combustion chamber, the cross-sectional area of which is greater than the recess cross-sectional area forming the nose (11) and that the running surface (2) of the oil scraper ring (1) is of conical design. The oil scraper ring is especially suitable for internal combustion engines. <IMAGE>

Title: Method for measuring the distribution of washing, especially in washing machines and spin driers
Inventor: WIPPERFUERTH FRANZ-JOSEF ING G
IPC: D06F33/48
Filed: 1988-04-14
Abstract: The method according to the invention is to be used precisely to determine washing imbalance in the case of a predetermined constant measured rotating speed. Known methods determine the change in the actual rotating speed of the motor within a prescribed period by means of tachometer generator output signals when there is a constant measured rotating speed. The deviation of the latter from the desired rotating speed of the motor is used to measure the extent to which the washing is properly distributed and/or the extent of the imbalance. As this involves conclusions being made concerning the rotating speed of the washing cylinder from the rotating speed of the motor, the method is not very accurate. In the case of the method according to the invention, the actual values of frequency fluctuations in the tachometer are now measured not within a prescribed period, but over a previously determined number of tachometric periods, in a so-called measuring period, and are compared with a known total tachometric frequency value. The deviation measures the extent to which the washing has been properly distributed. A measuring period is composed of a plurality of measuring phases, one measuring phase precisely matching one revolution of the washing cylinder. The new method is suitable for measuring washing imbalance before high-speed spin drying actually takes place, in the case of electronically regulated fully automatic washing machines and spin driers. <IMAGE>

Title: Method for diminishing residual gas in high-vacuum systems by getter layers and for generating these, and correspondingly coated high-vacuum systems
Inventor: WINTER JOERG DIPL PHYS DR
IPC: C23C16/32
Filed: 1988-04-28
Abstract: For the purpose of diminishing residual gas in high-vacuum systems, boron-carbon layers are suitable as getters, which are deposited by plasma discharge from a borane/hydrocarbon mixture and which, in particular, may have a thickness of from 1 to 10<4> nm. Such layers are obtained, in particular, from gas mixtures (which may contain carrier gas) of diborane and hydrocarbon by plasma discharge at from 10<-4> to 1 mbar. Preferably, the entire inner walls of the vacuum system are coated, and the wall temperature is maintained, during the deposition, at </ &tilde&  400@C. Such layers further deploy a protective effect at particularly high thermal and/or radiation loads and they can be regenerated by HF- (RF-, high-frequency-, radio frequency-)assisted glow discharge in rare gas (noble gas).

Title: Slip-controlled brake system with brake master cylinder
Inventor: BURGDORF JOCHEN
IPC: B60T8/44
Filed: 1988-06-01
Abstract: For controlling the pressure on the outlet of a pump and for positioning the pedal during brake slip control, it is proposed to attach an additional unit to an existing brake master cylinder, which unit contains a transmission piston (5) and a check valve (30). By way of a valve piston (28), the closing body of the check valve is loaded by the pressure in the brake line (18') against the pressure on the pump outlet. The valve closing body is thereby pressure-balanced so that no forces are transmitted to the tappet (37). The ramp (40) on the transmission piston (5) therefore does not need to be separately hardened. <IMAGE>

Patent DE-3824574-A1 (DE)
Title: Method for casting precision castings
Inventor: HAEUSLE MICHAEL
IPC: A44C27/00
Filed: 1988-07-19
Abstract: This method relates to an improvement of the hot-wax casting method, which is widely used especially in the jewellery industry. The improvement consists in that (a) as the moulding composition for the production of the negative mould in which, in turn, the wax pattern is cast, use is made of a pourable silicone rubber which can be hardened to give a silicone elastomer and that (b) the silicone-rubber mould halves are pretreated by being dipped in a hot water bath containing a surface-active agent and that (c) the hot spray wax of the pattern is injected into the negative mould using a vacuum. The precision castings cast in accordance with this variant of the method can have increased accuracy in reproducing the shape of the mould and require less intensive finishing. As the positive moulding composition, it is also possible to use plastics and low-melting metal alloys instead of wax.

Title: Automatic small-parts store VKL having a modular design in the form of European standard containers
Inventor: JAKOBY RENE DIPL ING
IPC: B65G1/02
Filed: 1988-08-04
Abstract: The invention relates to a fully automatic small-parts store in the form of European standard containers which can be used in both a stationary and in a mobile manner. The VKL is indispensable as an integrative component for an optimal material-flow solution. Parts which are small and thus can per se only be handled in a very time-consuming manner can, in this manner, be transported rapidly and in a path-optimised manner to the correct site in the material-flow system in the requested number and sequence. This economical solution was previously absent in short-term applications, e.g. building sites, assembly work on site etc. The problem was technically solved in such a manner that the complete small-parts store is accommodated in a mobile container. The latter is modified on the inside and outside without the universal transport function being impaired. A container thus contains both store racks and storage and retrieval equipment, and the computer control. Using this invention, the dynamic provision according to the goods-to-man principle, one of the main prerequisites for rational supply with small parts, can also be realised on site.
