Title: Self-adhesive materials coated with crosslinked acrylic! polymers - contg. copolymerised benzoin (meth)acrylate! as photoinitiator
Inventor: GUSE GUENTER DIPL CHEM DR
IPC: C09J7/38
Filed: 1977-09-30
Abstract: Self-adhesive materials coated with a polyacrylic acid deriv. contg. a copolymerised photo-initiator, and crosslinked by brief UV irradiation, are made using 0.01-5(0.1-2) wt. % benzoin (meth)acrylate as photo-initiator. Used esp. for prodn. of self-adhesive tapes. The photoinitiators are readily obtained in yield of aound 90% pure cpd. by reaction of benzoin with (meth)acryloyl chloride in CH2Cl2 in presence of triethylamine. This compares with 60% yields of more complex (meth)acrylate esters used for this purpose, which require a multi-stage synthesis. Amounts up to 5% are readily copolymerised and the copolymers are lighter in colour. Thermal stability is excellent.

Title: Twin non-return valve - has choked drain channel connected to each pressure chamber to be opened and closed by slide
Inventor: BRUNNER RUDOLF
IPC: F15B13/01
Filed: 1978-01-16
Abstract: The twin non-return valve has a housing in which is a valve seat for every hydraulic channel which passes through the housing into two pressure chambers. A spring-loaded closing element is fitted to each valve seat, a common slide being arranged between the pressure chambers. The slide is moved out of its base position when there is a pressure difference between both pressure chambers and lifts a closing element from its valve seat. A choked drain channel (23a, 23b) is connected to each pressure chamber (5, 6). When the unblocking slide (18) is in its base position, the drain channel is opened and when the slide is moved out of its base position, the channel is cut off.

Title: Class=D LF amplifying circuit - has P-channel FET controlled by negative voltage pulses and N-channel FET in series controlled by positive ones
Inventor: PELTZ GUENTER DIPL ING
IPC: H03F3/393
Filed: 1979-05-18
Abstract: The amplifying circuit is for rectangular wave signals pulse-width modulated at a low frequency.

Title: Ultrasonic pulse range finder with swept receiver gain - suppresses spurious echoes from nearby objects off beam axis
Inventor: POSCHMANN HORST
IPC: G01S7/529
Filed: 1979-06-13
Abstract: A hand-held ultrasonic range finder transmits a short pulse in a narrow beam (7) when a button (6) is pressed. The echo is received by a transducer (8) whose output drives the gate of a FET (52), which drives the timing circuits. Spurious echos from nearby objects off the beam axis are suppressed by sweeping the gain of the FET, from min. at the instant of transmission, up to max. after approx. 15mS. The FET cathode resistor (54) and bypass capacitor (C) are chosen for max. gain. They are shunted by a resistor (56), diode (D) and gate (G) to ground, this resistor being preset for min. gain. The gate is closed by a pulse from the transmitter (12) which blocks the diode and allows the capacitor to charge. The rising gain practically compensates for the fall of echo signal strength with time/range.

Title: Dough shapes mfr. - between feed roll and moulding roll with roughened surface by sand-blasting prevents sticking (NL 15.1.80)
Inventor: TOGT JACOBUS CORNELIUS VAN DER
IPC: A21C11/08
Filed: 1979-06-28
Abstract: Shapes of dough or marzipan are produced by guiding the paste in a layer over a feed roll which is faced by a moulding roll. The desired shapes are engraved in negative form on the periphery of the latter. A cutter blade skims off the shapes from the periphery of the feed roll. Both the shell and the countersunk shapes are given a rough surface by sandblasting. The roughened surfaces result in point contact and prevent any sticking of the dough to the moulding roll. Manual powdering of the rolls is not necessary any more and imperfect shapes have been eliminated.
