Patent DE-3836280-C1 (DE)
IPC: H04N17/00
Filed: 1988-10-25
Granted: 1989-08-10
Abstract: For determining the transmission function of a video camera, a bar pattern is taken in which the width of the bars is selected to be sufficiently small so that their influence on the amplitude and phase response of the electric pulse that is produced upon scanning of a bar in the camera is negligible; the narrow electric pulses thus produced at the output of the video camera are selected and subjected to Discrete Fourier Transformation.
Patent DE-3913691-C1 (DE)
IPC: C08J5/12
Filed: 1989-04-26
Granted: 1990-09-06
Abstract: The invention concerns an aqueous binder dispersion for vulcanizing rubber on to substrates which are stable under the conditions of vulcanization, consisting of: a halogenated copolymer which, in addition to other components, contains an alkylation-active monoalkenylaromatic alkyl halide; polyfunctional aromatic nitroso compounds; pigments, carbon black, anti-foaming agents, emulsifiers and other additives. The aim of the invention is to improve the adhesive strength, at the same time avoiding the use of capped isocyanates. This is done by adding, to increase the adhesive strength, homopolymers or copolymers of vinyl acetate, which are also saponified to a certain extent, as well as, optionally, other customary additives.

Patent DE-4220410-C1 (DE)
Inventor: MEYER STEPHAN
IPC: G01R31/11
Filed: 1992-06-19
Granted: 1993-11-25
Abstract: The invention relates to a process for finding a fault on an electric message transmission line in which a pulse is applied to one end of the data transmission line and a reflected signal is detected at the same end. For the precise detection of even a fault occurring at a considerable distance, line pulse responses (J1, J2, J3) are detected and stored for different line lengths of a typical line. When a Dirac pulse is applied to the data transmission line (1), the correlation coefficient (rI1, rI2, rI3) is calculated from sections of the detected pulse response (JA) and the sections of time-corresponding, stored line pulse responses (J1, J2, J3). With the reflection factor (R(t)) obtained, the correlation factor (rJ1, rJ2, rJ3) is multiplied by a computing value (VxyJ1) formed from quotients of a value from the respective section of the pulse response (JA) and the line pulse response (J1, J2, J3). The conductance (Gab(t)) of the error is determined from the reflection factor (R(t)) with the impedance level (Z).

The sleeve part 4 is held by the joint pin 3 of a bearing block 2 which is mounted on the room-side end face of the fixed frame. The second leg 10 of the intermediate piece 8 is provided, near the region of transition in the first leg 9, along the longitudinal centre with a cutout or perforation, into which can be engaged a nose 15 set off along the longitudinal centre at the rear end of the hinge arm 7. The tab 6 of the sleeve part 4 can, in either of its two possible 180 DEG  end pivoting positions, be fixed relative to the second leg 10 of the intermediate piece 8 by snap-catch devices, in each of which a catch projection engages into a catch recess. There is provided as a catch projection, on or in the vicinity of each transverse edge of the sleeve-part tab 6, a catch tooth projecting out of the plane of the latter towards the second leg 10 of the intermediate piece 8, whilst the cutout or perforation of the second leg of the intermediate piece is used as a catch recess. One catch tooth can be engaged in each case in the cutout or perforation and has a blocking flank which engages behind a longitudinal edge of the cutout or perforation and which blocks the reverse rotation of the sleeve-part tab 6 relative to the intermediate piece 8. <IMAGE>

Title: Roof ridge covering system with good ventilation - has suitable gaps to allow uniform air circulation, with inexpensive flexible parts and crepe paper strips coated each side with thermoplastic
Inventor: FLECK OSKAR
IPC: E04D13/17
Filed: 1992-12-05
Granted: 1994-02-17
Abstract: A roof ridge cover is fixed to the ridge beam by its centre area where it has an air vent, the ridge beam also having covers. The edges connected to the centre area cover the gaps between the ridge and the two adjacent roof covers. The central area is a plastic component with openings, spacers to the ridge and spacers to the supports for the longitudinal edges of a ridge. The edges concerned consist of extensible strips of crepe paper coated on both sides with thermoplastic polymer; they conform to the surface shape of the roofing cover sheets. In the direction parallel to the ridge the edge areas have an extensibility of up to 35%, of up to 3% at right angles to that, and a recovery of up to 2% in the extended areas. The edge areas have at least one adhesive strip running along the underside facing the roof cover sheets and this is covered with an easily removed top strip. The adhesive is pref. a silicone, the cover strip is pref. a water-repellent paper, and the centre area is pref. an entropy-elastic polymer. ADVANTAGES - The ridge design provides uniform roof ventilation by its openings. It remains flexible and has inexpensive edge areas which are not sensitive to temp. variations and therefore provide permanent seals.

The finger spindle (4) can be on the side of the grip spindle furthest from the stop. USE/ADVANTAGE - Particularly for a rotary press. Reliable setting of grip fingertip position when shut with press running.

Title: Actuator device
Inventor: GANSER MARTIN
IPC: B60H1/00
Filed: 1994-04-07
Granted: 1995-04-20
Abstract: Apart from the use of stepping motors and pneumatic actuators, DC motors with gearboxes are also used for actuator devices of this type. Exact positioning is carried out by means of potentiometer or Hall transmitter sensor systems and correspondingly accurate switching-off of the motor. In addition, position detection by means of clocked motor drive and motor current analysis is known. In the case of the novel actuator device, a mechanical system which is driven at the same time and has a potential energy which varies along its movement travel is coupled to the actuator in such a way that it influences the servomotor current such that the respective position of the actuator element can be detected by a control device using the evaluation of the motor current which characteristically depends on the force exerted by the mechanical system on the actuator element. Use, for example, for actuators for ventilation flaps in motor vehicle air-conditioning installations.
