Title: Flying missile arming distance detector - feeds reflected laser pulse to two distance gates with series-connected integrators whose voltages are evaluated
Inventor: SPIES HANS
IPC: G01S17/18
Filed: 1980-06-03
Abstract: The detector uses transmit time measuring of laser pulses for determination of the arming distance of a missile on its flight-path towards a target. The reflected pulse, as known, is supplied to distance gates (108,109) associated with a different distance. Behind the gates are series-connected integrators (110,111). An evaluator (112) can check-the integrator voltages by a continuous comparison. The comparison gives which ever is the first highest integration voltage, as well as the later equality of these voltages. If only a single distance gate is available, it is energised by a clock pulse generator and a gate exciter. The power control for each transmit pulse uses pulses of sequentially increasing time interval from the transmit pulse. To this gate may be sling-connected an integrator, with a control counter which also energises a multiplexer.

Title: Electric drive unit for trolley bus - has free running diode and nonlinear resistance providing rapid energising path for acceleration during gear changing
Inventor: BRUNNECKER UWE DIPL ING
IPC: H02P7/282
Filed: 1980-10-24
Abstract: The compact electric drive unit for a trolley bus uses a DC motor with a controlled free-running diode connected in parallel across its field winding and with a starting resistance connected in the armature circuit during start-up. The braking circuit includes the armature, a mechanical switch, a thyristor and a braking resistance. Neither the thyristor or the free-running diode has an extinction circuit, but a second free-running diode and a non-linear resistance are coupled in parallel across the latter. The controlled free-running diode can be extinguished by a short firing of a DC regulator so that the second free-running diode and the non-linear resistance form a rapid energising path for the field winding for rapid acceleration during gear changing. The drive is compact and cheap to mfr.

Title: Spherical plain bearing for a mixing-screw tubular shaft of a screw mixer
Inventor: BOLZ SEN ALFRED
IPC: B01F7/02
Filed: 1981-03-10
Abstract: The invention relates to a spherical plain bearing (ball-and-socket joint) for a mixing-screw tubular shaft of a screw mixer, which bearing is arranged at the vessel bottom of a mixing vessel and accommodates the motion, both rotary and swivelling about this bearing, of the mixing-screw tubular shaft. The object of the invention is to refine the spherical plane bearing in such a way that it can be used in the production of foods and pharmaceuticals without incurring the risk of contamination of the mixed product, and that, furthermore, the service life and the antifriction properties of such a spherical plain bearing are considerably improved. The invention is characterised in that the spherical plain bearing consists of a bearing ball and a bearing shell, which can be rotated and swivelled relative to the bearing ball, and in that the bearing ball and the bearing shell, in the zone of the surfaces in contact, have an oxide-ceramic cladding. According to the invention it was found, surprisingly, that by the use of a combination of materials in the form of oxide ceramic for the bearing ball and of oxide ceramic for the bearing shell advantages are achieved which could not be foreseen.
