Patent DE-2151550-A1 (DE)
Title: Mixing extension to extruder
Inventor: STEPHEN HOOK WILLIAM GEORGE
IPC: B29C48/67
Filed: 1971-10-15
Abstract: Mixing appts., in which material is forced longitudinally under pressure through a sleeve or barrel within which there rotates a core possessing longitudinal perimeter grooves, each housing an idling roller, as in DT 2024825, is improved by each groove being so shaped in cross section that it diverges slightly away from the roller on the trailing side of the latter, thus forming a wedge-shaped portion into which the material is squeezed. Specif., the opposite or leading edge of the groove may be cut back to a chamfer. The mixer is esp. intended for use in association with a screw extruder, to prevent agglomeration of pigment or other additives incorporated in the mix.

Title: Epoxidation of olefins - using an oxidisable copper cpd as catalyst which can be regenerated
IPC: C07D301/08
Filed: 1971-11-09
Abstract: The olefin (ethylene, propylene) is epoxidised by passing it as vapour with O2 at 300 degrees C (pref. 150-250 degrees C) over a solid material contg. a Cu cpd. (on a support, e.g. alumina) in which the Cu is in a low oxidn. state, and the epoxide product is sepd.

Patent DE-2253500-A1 (DE)
Title: Anti-jamming system for conical scan radar - employs pilot tone modulation for regeneration of scan signal
Inventor: SIKORA HARALD
IPC: G01S7/36
Filed: 1972-11-02
Abstract: A jammer is used to confuse a conical-scan-radar operated firing guidance system. It has a send-receive switch a transmitter and a receiver. It amplifies the modulation of the scan frequency of the radar aerial system and, by means of a scan inverter produces a phase shift of approx. Pi. The radar controlled firing guidance system includes a filter which only accepts such spectral components as will serve for the generation of a pilot tone with which the radar transmitter is modulated. The scan signal is then regenerated by demodulation of the pilot tone in an amplitude demodulator (AD), and thus the jamming is overcome.

Abstract: Combination-colouring of Al or Al alloy articles, following anodic oxidn. and electrolytic colouring in an acid soln. of a metal salt with AC 1-50v for 0.1-15min., is effected by immersing the article in an aq. soln. of a heteropolyacid of Si or P with Mo or W, whereby, without supplying current, an electrochemical reaction sets in with the previously electrolytically incorporated metal ions which are more electronegative than Cu in the electromotive series. Method is used for forming decorative and/or wear-and weather-resistant coatings for internal and external use. Durable gray shades are obtd. Heteropolyacid can be prepd. in situ by reacting Na molybdate or tungstate with Na silicate or phosphate and HCl in an aq. soln.

Title: Device to warn of aquaplaning or black ice - has indicator for driver when differences in wheel speeds occur due to spin
Inventor: ROHRBACH CHRISTOF DR ING
IPC: B60R16/02
Filed: 1974-01-08
Abstract: The device can also be used for other motor vehicles e.g. trucks.

A control circuit can be used to alter the drive to the wheels. The receiver is a plate field type or an electromagnetic induction type. The receiver incorporates a frequency digital-to-analog converter and the output signals are subtracted from one another. A zeroing device is used and the current then operates a lamp or hooter. One of the measured wheels is a driven wheel and the other is a non driven wheel.

Title: Voltage adapted electric appliance - has current dependent resistor in series with resistivity rising with increased current
Inventor: DEUSSING GUENTER
IPC: H02M1/10
Filed: 1974-06-20
Abstract: The portable radio receiver is provided with a mains voltage adaptor without switching over. A current dependent resistor (L) is in series to the radio receiver and its resistance value rises with increasing current. Its voltage drop is approximately equal, at the highest possible resistance value, to the difference between the two usual mains voltages, being substantially smaller than this difference at the lowest encountered resistance value. In order to attain the desired operating voltage the receiver is rated for the lower of the two mains voltages. Preferably an incandescent lamp is used as the current dependent resistor, and its rated operating voltage value equals to the maximum voltage drop appearing at the same.
