Title: Hydraulic servo valve with control piston - two opposed, spring loaded thrust rods are fitted in axially bored control piston
Inventor: WEINZIERL HELMUT
IPC: F15B13/043
Filed: 1973-09-21
Abstract: Servo valve has a central piston in a control cylinder with feed and return bores and is moved proportionally to a servo force generated by an electrical control signal. The control piston is axially bored and in the bore are two opposed, spring-loaded thrust rods which are acted upon by the servo force and are guided on the cylinder front sides with play in thrust bearings. These rods, between them, accept a ball fitted into the bore with play. A radial orifice bore, which is connected with the pressure feed is fitted in the piston when the ball is at rest.

Title: Anchoring device for tool post or handle - has surrounding holder which fits in recess with two sets of double arm levers
Inventor: HENNING WILLI
IPC: B25G3/20
Filed: 1973-09-21
Abstract: The design is for anchoring the post in a recess in a hand tool or machine tool table. A particular application is for broom handles where the normal methods of fixing are unreliable. One of the sets of levers fits on a circular holder surrounding the handle. The other ends act on a tapering collar that is inserted in the tool recess. The other pair of levers fit above the ring holder and bend round onto the handle. The first levers have a serrated surface and this is at a thread angle so that the lug formed by the levers can be screwed into position.

Title: Vehicle energy transmission control - has pre-set critical friction coefficient with instruments sensing overrun and producing corrective signals
Inventor: SCHOENENBERGER ALBERT
IPC: B60T8/17
Filed: 1974-01-15
Abstract: The system concerns energy transmission between a wheel of a vehicle moving on a road surface. A control installation ensures the optimum energy transmission between wheel and road surface to the limit of a friction coefficient prevailing under normal road conditions. When the wheel passes a stretch where the adhesion conditions are deteriorated by abnormal behaviour of the wheel; such as skidding, blocking and gliding along the surface or spinning with the vehicle at standstill; is sensed as an information signal related to the velocity and/or energy transmission conditions of the wheel, fed into a computer which works out a corrective signal by which the original preset friction coefficient is adjusted to the new conditions.

Title: Indicating mechanism for bellows type gas meters - indicates position between dead centres for test calibration
Inventor: MOELLER MANFRED
IPC: G01F3/22
Filed: 1974-03-14
Abstract: The mechanism is for bellow-type gas meters in which an output shaft performs precisely one revolution for each working movement of a meter mechanism. The output shaft has a pointer on the end adjacent to a window next to the meter mechanism. The pointer is visible through the window and when it is aligned with an index mark it indicates that the meter mechanism is between the dead centre positions.

Title: Two point regulator with a controlled power thyristor - with triggering timed precisely by combining reference and output signal to give peaks
Inventor: SCHMIDBAUER WALDEMAR
IPC: G05D23/24
Filed: 1974-03-30
Abstract: The two point regulator consists of a measurement circuit, a difference amplifier and a power circuit. All circuits are coupled to a 220 V 50 Hz supply. The measurement circuit consists of a constant current limiter and two voltage divider circuits. The difference amplifier has one input voltage of trapezoidal wave form that is a reference input and a temperature dependent signal to the other input. The temperature dependent signal has a part sine wave profile. When summed the resulting output has two voltage peaks separated by a time interval. The two voltage peaks are of an amplitude sufficient to trigger the output load thyristor. In this way the triggering of the thyristor is precisely timed.

Title: Interference pulses suppression cct. - binary signals flow through resistor in RC cct.
Inventor: BREUNIG HANS DIPL ING
IPC: H04L25/08
Filed: 1974-04-25
Abstract: Interference pulses are superposed on the binary signals. A threshold amplifier is provided, whose threshold is adjusted to a value between the two binary signals. The resistor for the binary signals is connected to the threshold amplifier's non-inverting input, and is in series with a capacitor between the amplifier input and its output. A resistor is in parallel with the above capacitor. It satisfies a specified equation. The amplifier's threshold is adjusted to the mean value of the two binary signals' input voltages. The circuit produces no interfering hysteresis and ensures against interfering impulses no matter what their phase may be in relation to the working impulse.
Patent DE-2427102-A1 (DE)
Title: Echo compensator for two-direction transmission system - has reflected end signal forming echo signals and artificial echo signals for processing
Inventor: HOEGE HARALD DIPL PHYS
IPC: H04B3/23
Filed: 1974-06-05
Abstract: The sum of squares of all output signals of a multiple connection device for two echo path models is determined, and a correction factor for the residual echo is derived from the sum. The parameters of the second echo path model are determined by addition of those of the first model to the product of the correction factor multiplies by corresponding output signal of the multiple connection device. A second residual echo signal is determined by the second echo path model. If the absolute value of the second residual echo signal is below a specified threshold, the second echo path model becomes a new first model; if not, the existing model is used. The new first echo path model is used for the artificial echo signal generation.

Title: Transparent hollow body with incrustation protection - sealed internal cavity contains solid bodies with high absorption capacity
Inventor: HERMANUS HEINRICH
IPC: G05G1/10
Filed: 1974-06-06
Abstract: In the internal cavity (9) one or more solid bodies (2) consisting of material with a high absorption capacity are visibly or invisibly incorporated loosely and of indeterminate form, colour, numbers and size. These bodies can be fine-grained solid bodies mixed with powdered metal which are incorporated loosely in the cavity. Solid bodies made of a material with a high absorption capacity can be incorporated within diaphragms (3, 4) in indeterminate form, number and size. Such a solid body can absorb up to 40% of its own weight in moisture, but here there is a multiple safety factor for keeping the cavity absolutely dry.

Title: Pneumatic brakes for lorry and trailer - with opposing force on towing unit brake cylinders to act if trailer attached
Inventor: BECK SIEGFRIED
IPC: B60T17/18
Filed: 1974-11-13
Abstract: The towing unit pneumatic brakes are fitted with a control valve to supply to supply the trailer brakes when the trailer is connected. Without a trailer the towing unit brakes operate at maximum levels. When the trailer is attached, the towing unit brakes are modulated by an amount proportional to the trailer brakes. This prevents the trailer from slewing, or jacknifing. A simple layout for the modulation comprises a special brake cylinder in which the main braking force is opposed by a smaller piston which is subjected to the trailer brake pressure. No other control valves are required.
