Title: Interative A:D converter for PCM telephone system - has fixtra operational amplifier and reference to compensate extra voltage on capacitor due to offsetting
Inventor: HOEFER ERNST
IPC: H03M1/00
Filed: 1976-02-16
Abstract: The iterative AD converter, for a PCM transmitter (e.g.) telephone) system, contains an operational amplifier comparator (Vgl) comparing the voltage on a capacitor (C) with the output of the D/A converter. The capacitor is charged via a switch (controlled by a counter) from the output of a second operational amplifier. The second op.amp. (Op) is coupled by its inputs to the analog signal and to a reference. The reference is chosen to compensate for the extra volts appearing across the capacitor due to the offset voltages of both amplifiers and due to the opening of the switch (Ss).

Title: Traffic light sequence alteration by privileged emergency vehicle - uses ultrasonic or IR signal transmitter in vehicle and receivers on lamp standard in front of road junction
Inventor: HARTIG ZOLTAN
IPC: G08G1/087
Filed: 1976-05-25
Abstract: The device enables the sequence of traffice lights at acity road junction to be altered by a privileged emergency vehicle using an ultrasonic or infrared signal transmitted from the vehicle to a small receiver located at the road junction.

Title: Wide-range direction finding system - evaluates azimuth and elevation angles for each antenna via summed signal pairs to determine correct values
Inventor: DEUBACH GERHARD DIPL PHYS
IPC: G01S3/38
Filed: 1976-06-15
Abstract: The system uses a number of antennae or antennae groups from which respective output voltages are obtained. The amplitude and phase values for each output voltage are obtained and fed to A/D converters before obtaining the product of the amplitude and the cosine of the phase and the product of the amplitude and the sine of the phase. Successive such pairs of values are used to obtain mean values which are used together with digital propagation coefficients to give the azimuth and direction, e.g. using a digital processor. The directional characteristics of the overall antenna array are evaluated from obtained sum signals using the measured parameters with a max. value detector evaluating the summed signal to select that for which the determined azimuth and elevation angles correspond to the azimuth and elevation of the directional wave.

Title: Distance measurement on base range finder principle - converts optical information to digital format and calculates range electronically by cross-correlation method
Inventor: HESSE KLAUS DR RER NAT
IPC: G01C3/08
Filed: 1976-09-14
Abstract: The optical section works on the base range-finder principle with the two optical channels (1, 11) having respective prisms (2, 21) and a common divided prism (3). The two target images are displayed vertically displaced on the surface of the image sensor (4). The electrical output from the sensor (4), which need not operate in the visible part of the spectrum, is sampled, converted to digital format, and stored. Cross-correlation calculations are then performed on the horizontal deviation of the two images to obtain the target angle and thereby the distance. Evaluation by electronic means considerably reduces sensitivity to mechanical disturbances.

Title: Fluid cleaning appts. for small wooden chips - has centrifugal discharge pump and discharge conveyor raising up foreign bodies above fluid level
Inventor: STEHLE WOLFGANG DIPL ING
IPC: D21B1/02
Filed: 1977-01-11
Abstract: The cleaning appts. comprises a fluid bath with separate discharge devices for the floating and sinking chips and a separating device for separating the sinking chips from heavy foreign bodies wherein the sinking chips are driven along above a discharge opening (6) at the base of a fluid container by a conveyor pump (8) which produces a circulating current and is designed as a discharge pump. The pressure line (29) of the pump is guided towards a dewatering device (18) whilst beneath the discharge opening (6) screened off from the circulating current a mechanical discharge conveyor (7) is fitted to automatically raise up the foreign bodies above the level of the fluid. The sinking chips are exposed to the circulating current and thus moved about for a longer time which means they are washed more thoroughly. Since the foreign bodies are removed automatically the operating costs are reduced. The pump is pref. a centrifugal pump with a rotor (25) which rotates substantially free or contact with the sinking chips.

The innermost one accommodates the ring in the final sealing position and the socket has an internal face to prevent movement beyond it. The initial mounting (4) has a cylindrical or tapering inner wall, and the ring (2) is of triangular cross-section, being inserted with its edge directly in front of a socket shoulder. The latter is short enough for the ring to roll over and bring its face towards the base of the socket into the sealing position against the face (9) provided in the socket.

Title: Sewage aeration device - with adjustable inclined deflector plates for swell ejected by aeration impeller
Inventor: ARMBRUSTER WERNER DIPL PHYS
IPC: C02F3/14
Filed: 1977-03-02
Abstract: Sewage is treated in an aeration tank by a centrifugal impeller which revolves near the fluid level around a vertical axis and projects the fluid radially in a heavy swell. One or more deflector plates are arranged with an angle f incidence of 30-90 degrees against the horizontal within the action radius of the impeller, partly above and partly below the water level. This causes the air bubbles contained in the swell to be kept under the water surface for longer periods so that the mass exchange between water and oxygen in the air is intensified. The deflectors also act as spray preventers and keep germs and smells away from the environment.

Title: IC engine of swashplate type - has oil pressure controlled to ensure hydrostatic lubrication of swashplate bearing over entire operating range
Inventor: KLAUE HERMANN DR ING
IPC: F01B3/00
Filed: 1977-05-23
Abstract: The engine has a cylinder block (1) with several cylinders in which pistons (4) reciprocate. Each piston has a piston rod (5) which ends in a spherical shoe (52) which seats in a recess in a swashplate (6). The swashplate is supported on a spherical bearing (7) on a sphere (8) on the internal end of the output shaft (11). A pump driven from a gear (112) on the shaft delivers oil through passages (20, 21, 22) in the mechanism to the swashplate bearing (7). Circular seals (23, 24) at the ends of the bearing prevent escape of oil. The oil pressure does not exceed the mean pressure on the bearing produced by the pistons and is greater than the bearing pressure at part load. This ensures hydrostatic lubrication over teh whole operating range.
