Title: Fitment for drawer-like extensions in furniture - includes fastening angles and spring plate for alignment and adjustment (OE 15.9.77)
Inventor: GRUEBEL ALOIS
IPC: A47B88/00
Filed: 1977-06-15
Abstract: The fitment for drawers etc. includes two fastening angles (1) each having two arms of which one (3) has recesses (4) for taking up the fastening screws for an end wall of the drawer whilst the other lateral arm (2) is screwed to an assembly holder (14) which is mounted directly or indirectly against the base of the drawer. A spring plate which can be resiliently deformed across the direction of its main extension is located between the assembly holder (14) and the lower region of the lateral arm (2) and both the plate (8) and the lower region of the arm are provided with interengaging guide grooves (6) and lugs (11) which thereby allow a displacement of the fastening angle (1) in the plane of the lateral arm (2). Through this relatively simple construction the drawer can be fitted for perfect alignment since there is play in all directions.

Title: Potential-free contactless car lamp monitoring - using evaluation of choke coil inductivity change caused by lamp current
Inventor: GRAF ALFONS
IPC: B60Q11/00
Filed: 1977-09-19
Abstract: An AC generator(X1) produces a constant frequency voltage from a battery voltage. The AC feeds a series connection consisting of winding(w3) of the iron-cored choke coil(m1) and of the capacitor(K1). Due to the magnetising effect in the windings(W1, W2) produced by the bulb currents(J1, J2) the inductivity of the choke coil(m1) becomes very low, but the AC voltage(U2) on the capacitor(K1) becomes very high. The threshold value on the limit value indicator(X2) is set so that independently from the tolerance of the bulbs, the hysteresis in the iron core, and the tolerance of the battery voltage the control light(h3) lights up only when both bulbs(h1, h2) are alight.

Title: Fibre-reinforced thermoplastic, elastomeric or duroplastic extrudate - is prepd. by previously subbing the reinforcement with a low polymeric adhesion aid which sets to ensure good adhesion
Inventor: WACHSMANN MICHEL-ARNO DIPL ING
IPC: B29C48/12
Filed: 1978-02-02
Abstract: Process or reinforcing extruded plastics by fibrous strands which have been impregnated with reactive adhesion adjuvants comprises using such adhesion adjuvants as are adapted to impregnate the fibres by virtue of their low viscosity. However, the adhesion adjuvant solidifies during the fabricating step within the extruder so that firm adhesion of reinforcement and matrix is achieved. Prods., e.g. profiles, films, sheets of almost any cross-section can be continuously mfd. Depending on the type of reinforcement used, stiffness, resistance to flexural stresses, and tensile and compressive strength can be considerably increased.

Title: Continuously depositing pore-free copper foil on endless belt - over regularly replaced intermediate metal film of chromium, nickel or cobalt
Inventor: HUTKIN IRVING JOSEPH
IPC: C25D1/04
Filed: 1978-02-13
Abstract: Cu foil is produced continuously by deposition onto an endless belt the surface of which has been prepd. by electrodeposition of a film of Cr, Ni, or Co. That film is removed from the belt after the foil has been stripped, removal being affected chemically without damage to belt surface. The belt is made from stainless steel, aluminium, nickel, titanium, copper, brass, bronze, mild steel, iron or lead, and the intermediate film may be freshly deposited before each cycle of Cu deposition, or may be replaced as necessary to maintain the foil quality. The foil product is chiefly for use in printed circuits after bonding to a plastic film, but also for roof flashing in building construction. The frequently renewed substrate surface ensures that the foil is pore-free, while the need for interruption of the deposition process while the surface is cleaned is eliminated.

Title: Digitally controlling thyristor DC converters - by controlling thyristors conductive duration using time shifted and constant pulse trains provided by decoder networks
Inventor: KALINITSCHENKO ANATOLIJ JAKOVL
IPC: H02M3/139
Filed: 1978-06-28
Abstract: The method is for digitally controlling the thyristors of an m-phase thyristor-pulse D;C; converter. The duration of the conductive state of the thyristor for each phase is changed by sending time-shifted and time-constant pulse trains from each of m-control channels to the thyristor. The onset of operations of the thyristor of each phase is shifted 1/m of a thyristor switching period at the same time. In the process of changing the durations of the thyristor's conductive states within the entire control range, each control channel is connected in succession to the thyristor's of the respective pulses on reaching the max. value of the control zone for each channel. A counter driven by a master oscillator supplies pulses to decoder networks which each receive another input from counter. The networks feed a logic network of AND gates to selectively cylically permute the connections from the networks, thus carrying the time shifted pulse train to turn off the thyristors. A decoder network response to counter gives the time constant pulse train.
