Title: Multi-stage remotely controlled pushbutton switch e.g. for controlling hydraulic pump
Inventor: POTZI KARL-HEINZ
IPC: H01R43/048
Filed: 1995-12-02
Abstract: The multi-step remote operating pushbutton or key unit held in the hand, designed so that if the grip is loosened, the working cylinder operating a plunger, press or similar is stopped. The motor driven hydraulic pump supplies hydraulic fluid to a single acting hydraulic cylinder. Two possible switching positions from the rest condition can be selected. The possible switching of the pushbutton unit are as follows: the switching from the rest condition to a working position. The connected hydraulic pump is directly or indirectly controlled, across a connected electric or electronic control, such that the connected tool is set in motion, in the direction "for executing conversion work". This is maintained, as long as the operator, holds the button pressed in this position, and the tool has not yet reached its end position.

Title: Roller press for moving webs and ensuring effective lubrication
Inventor: LINK CHRISTOPH
IPC: D21G1/02
Filed: 1996-01-09
Abstract: In a roller press assembly, the press section (22) of the support (16)  is defined by outer edges (48,50) straight and parallel to the roller axis, in the peripheral direction (U) of the roller (10), in the pressure zone (18). The width (B) of the press section (22) between the outer edges (48,50) is smaller than the max. outer diameter of the press piston (62).  Preferably the support (16) and the press section (22) have a radial movement in relation to the carrier (12) in a swing mounting towards the roller axis. The support (16) is secured against tilting and/or riding in the peripheral direction (U) of the roller mantle (14) by at least one stabiliser (24,26) at the support (16) at a gap from the press section (22). The stabiliser(s) is (are) carried by an arm (44,46) attached to the press section (22) on both sides. The stabilisers (24,26) provide a sliding support at the inner running surface of the roller mantle (14). The press section (22) has two hydrostatic pockets (28,30) flanking the roller (10) on the axial line (A) to prevent tilting of the support (16) on the axial line (A) of the roller (10). At least two supports (16) with their press sections (22) are securely bonded together with mutual support, so that one support (16) and its press section (22) prevents tilting on the axial line (A) of the roller (10).

Patent DE-19605023-A1 (DE)
Inventor: JURISCH ANDREAS DR ING
IPC: G01R19/25
Filed: 1996-01-31
Abstract: The invention concerns a method of detecting an abrupt variation in an electrical alternating quantity, wherein a criterion for the occurence of the abrupt variation is formed from the sampled values of the alternating quantity. In order to be able to carry out this type of method such that the abrupt variations in the alternating quantity can be detected with a high degree of sensitivity, the alternating quantity (W) is evaluated in an FIR filter (4) with a transmission function (K) having a double zero point at the nominal frequency (fN), and the output signal of the FIR filter (4) is monitored to see whether it attains a threshold value indicating the occurence of an abrupt variation in the alternating quantity (W).

Patent DE-19705986-A1 (DE)
Title: Woven carpet production
Inventor: EIBOFNER SABINE DIPL ING
IPC: D03D27/00
Filed: 1997-02-17
Abstract: The woven carpet is composed of pile yarns and other yarns for the fabric structure to give a loop and/or pile surface and structured edges along the longitudinal sides.  The carpet is woven with the raw white pile yarns in the weaving design, independently of subsequent dyeing operations.  The woven carpet is tensed, and a dyestuff is applied at the same time continuously over the fabric width along the fabric length. After weaving and dyeing, the reverse side of the carpet is covered with a latex backing.  The carpet is woven as a rush or Wilton carpet, in a width of 4-5 m or more.  The structural yarns are mostly of synthetic fibre materials. The raw white pile yarns are mainly of polyamide, of all types, or they can be yarn-dyed polyamide pile yarns. The polyamide pile yarns have different dye affinities, to give multicolour effects. The pile yarns can also include other yarn types, and mixtures.  The edges of the carpet are woven without the pile yarns, or a leno edge can be formed or other weaving actions to give a firm edge.  The weaving density is set to prevent any sliding shift movements between the warps and wefts. All the required dye affinities are set at all points on the upper surface of the woven carpet. The dyeing action is specific to the yarn content of the carpet, to be applied while the carpet is taut without bunching or creasing.

Patent DE-19730572-A1 (DE)
Inventor: DULTZ WOLFGANG PROF DR DR
IPC: G01B9/02
Filed: 1997-07-17
Abstract: The invention concerns a double-beam interferometer (1) for electromagnetic radiation and a method for the compensation of dispersion or increase in the spectral resolution of such an interferometer. Using a polarizer (8), which is brought into the optical radiation path, a defined polarization state P1/2<0> is produced for the electromagnetic partial waves flowing into the arms of the interferometer. This polarization state is wavelenght-independent and can vary for both partial beams. Optical elements (11, 12) modify the polarization state P1/2<0> of the electromagnetic partial waves as a function of wave-length  lambda and each spectral component  lambda i is coded with a polarization P1/2 ( lambda i). An analyzer (9), fitted to the output of the interferometer, transmits an adjustable polarization state Pdet, whereby an additional wavelength-dependent phase difference  gamma ( lambda ) occurs between the partial waves of the spectral components. gamma ( lambda ) can be adjusted to obtain compensation of dispersion or an increase in the spectral resolution of the interferometer.
