Title: Focussing mechanism for optical non-contact length measurement - has diaphragm placed in beam path of light reflected from object surface
Inventor: ERTL FRIEDRICH DIPL ING
IPC: G01B11/24
Filed: 1977-09-16
Abstract: The focussing mechanism uses a light source focussed on the object face via an optical element (3). This optical element is connected to an oscillating drive (5) and to a displacement pick-up (13). In a decoder circuit a memory (12) connected to the pick-up and to the photo-receiver (9) stores the position of the optical element at the time of a maximum of the signal supplied by the photo-receiver. An indicator and/or recording device (14) is connected to the memory. The optical element may be a lens oscillating in the direction of the optical axis.

Title: Voltage measuring circuit - uses difference between two voltages as reference voltage for integrator capacitor discharge
Inventor: SCHEUPLEIN HARALD DIPL ING
IPC: G01R19/255
Filed: 1977-09-27
Abstract: The circuit has an integrator which is used for charging a capacitor during a specified time interval. It is used for counting the time of the capacitor discharged to a reference voltage. In order to measure a resistor (Rx) connected to input terminals (MP1, MP2) and used for the capacitor (C1) discharge, the difference (Uref-Ux') between the reference voltage (Uref) and voltage drop (Ux') across the resistor (Rx), a part of a voltage divider connected across the reference voltage (Uref), is used instead of the reference voltage.

Title: Road sweeper brush height control - with adjustment from hydraulic cylinder using fluid tapped from brush drive motor feed line
Inventor: KUGELMANN SIEGFRIED
IPC: E01H1/05
Filed: 1978-05-18
Abstract: The height-guiding system is applied to a brush roller and/or plate brush rotating on a road-sweeping machine. The brush moving up and down in conformity with the contour. The brush is counterweighted by an adjusting force generated by a hydraulic cylinder (10) activated on one side. Oil pressure energy for this is extracted directly from the oil pressure engine's supply lead (3) feeding the brush (4). Adjusting force is thus precisely regulated in proportion to the torsional moment emanating from this engine.

Title: Filter press with automatic opening - having carriage on toothed track with pick=up lever which also unlocks clamp on on next plate to be picked up
Inventor: WILMS HANS
IPC: B01D25/172
Filed: 1978-11-03
Abstract: Filter press has two carriages mounted on toothed rails running along the side of the plates, the plates being clamped together by a hydraulic ram. One carriage has a pickup arm in the form of a lever which fits behind projections on the sides of each plate and moves them in turn to the other side of the press for cleaning etc. The other carriage has a fork which slots onto the projection on the next plate and holds it while the one in front is pulled away. The pickup arm on the first carriage is a pivotted lever which tilts when the carriage is moved back against the next plate. This serves to depress the cylinder controlling the fork locked onto this plate and thus to release it. The carriage on which the fork is mounted then moves back and locks onto the next butone plate. The front carriage then extracts the next plate. For use as filter presses. Automatic opening presses are known as described in parent patent. The system here described is much simpler in concept and more reliable in operation.

Title: Test signal generator for PCM signals - has last and penultimate stages of shift register coupled back to input via modulo-two adder
Inventor: POSPISCHIL REGINHARD DR ING
IPC: H04B17/40
Filed: 1979-01-11
Abstract: The test signal generator has an n-stage clocked shift register with feedback whose outputs of the nth and (n-1)th stages are connected via a modulo-2 adder to the signal input of the register. A setting device detects when a given first clock time point is reached and sets the individual stages of the register via the clear and set inputs. During the next clock time point a signal is passed to the registers input that is the inverse of the first clock time point. The register contains 6 D-flip-flops. The Q-outputs of the fifth and sixth D-flip-flops are connected to the input of the modulo-2 adder. The period length is reduced by 4 bite from 63 to 59 bits.

Title: Printed circuit board with flexible and rigid areas - has slots made in rigid layer for removing flexible portions before pressing
Inventor: BISCHOFF ERNST
IPC: H05K3/00
Filed: 1979-04-09
Abstract: The method of making printed circuit boards includes the use of thin material (5) of laminated construction and thick non-laminated material (R) with a flexible foil (FF) on top. Rigid areas (S) can alternate with flexible areas (F) by removal of the laminated and non-laminated layers selectively.

Title: Support claw for suspending load - has two hook elements engaging over U=shaped profile and connected together by bolt
Inventor: KASSEL PAUL
IPC: E21F17/02
Filed: 1979-06-07
Abstract: The device is used in an underground mine. Two congruent hooks each have one arm engaging behind the profile and a larger one ending at a connecting screw in front, with a linking open intermediate section and a pressure piece to make up a claw for suspending loads on a support profile. The shorter arm (11) has an end section, running parallel to the root (21) of the longer one (13), adjoining the intermediate piece (12), and correspondingly shaped. The end (14) holding the screw (15-17) is similarly profiled, and has a recess (22) with round periphery to guide the pressure piece (23, 24). This has increased resistance to sloping tension and longterm alternating stresses.
