Title: Ternary plastics waste compsn - comprising polycyanamide, PVC, poly-olefin
Inventor: BEHNCKE HERMANN DR
IPC: C08G79/00
Filed: 1972-08-31
Abstract: A plastics compsn. based on refuse as raw material is mfd. by combining, with application of heat, 3 different polymer types (a), (b) and (c), whereby 2 of the polymers viz. (a) and (b) affect each other chemically whilst the 3rd viz. (c) modifies the characteristics of (a) and (b), and is itself modified by them without, however, chemically combining with either. The chemical action between (a) and (b) may be by HCl which is split off at above 150 degrees C from one of the component e.g., PVC, and catalyses the formation of polymer (a) which may be polycyanamide. Component (c) may be polyethylene.

Title: Electroplating pins for fixing to circuit boards - to facilitate soldering by forming a tin coating on part of the pins
Inventor: KNOLL RUDOLF
IPC: C25D5/02
Filed: 1973-03-27
Abstract: The pins are soldered at one end to the circuit board, the other end serving as wire-wrap or termipoint connection. For prodn. of a good soldered joint the pins are partially coated with Sn. The coating and soldering procedure is greatly simplified by coating the surface of the pins at one end with Sn by using the electroplating procedure, and a plating time, current density, and bath concn. so adjusted as to give sufficient Sn to effect a soldered joint without further addn. of Sn or a flux. The remaining surface, to be left uncoated, is covered with a silicone-rubber layer which is removed after the Sn plate has been applied.

Title: Engine balancing system - uses crank shaft webs as cam discs operating spring loaded balance weights
Inventor: THAUER PETER
IPC: F16F15/26
Filed: 1973-06-29
Abstract: The balancing mass is directly driven by a cam shaped disc fitted to the crankshaft. The mass itself is curved, and is held so that it can pivot about one or several points according to the design chosen. The cam disc moves with the crankshaft and has a set number of revolutions compared with it ( n = 1/3, 1/2, 1, 2, 3). The disc has a number of lobes (m). The balancing mass is held on to the cam by a spring. The cams are designed as an integral part of the crankshaft web. In the case of a four cylinder in-line engine the webs either side of the main bearing are used. The centre mass of the balance weight is given by a formula relating the radius of inertia, the clearance of the pivot from the centre of gravity and the distance from the pivot to the plane of operation of the balancing force.

Title: Flash light circuit with thyristor - is bridged by antiparallel diode and capacitor limiting flash duration
Inventor: ZOBEL ERNST-GUENTHER
IPC: H05B41/32
Filed: 1973-08-02
Abstract: The flash light circuit has a thyristor in series with the lamp across the supply. The thyristor is bridged by an antiparallel diode. The duration of the flash is limited by the series combination of a second thyristor, inductor (11) and capacitor (7), all coupled across the first thyristor (with both thyristors having the same conduction direction, i.e. coupled cathode to cathode). The first thyristor gate is connected to a two-resistor voltage divider which is connected at one end of the two thyristor cathodes (i.e. to the negative supply pole) and at the other end over a capacitor to the junction between first capacitor and inductor. This same junction is coupled over a resistor to the positive supply pole.

Title: Numerical control lathe chuck - has adjustable length face stop to accommodate various material lengths
Inventor: SCHWAN WERNER
IPC: B23B31/10
Filed: 1974-07-26
Abstract: In numerically controlled lathes, the chucking length is usually chosen to suit the longest parts which are to be machined and which have large overhang. This causes excessive waste when the shorter parts are machined. A chuck is therefore used which is provided with an adjustable stop face located centrally on the chuck and extending between the jaws. The part on which the stop face is mounted, is mounted at the end of a hollow shaft with internal thread. A stepper motor has a screw spindle which extends into the hollow shaft and is used to adjust the position of the stop face in the chuck, so that the stop face position can be modified to suit the chucking length of individual workpieces during the machining programme.

Title: Window push rod guide - has cylindrical body with slit and vertical extensions for positioning in frame opening
Inventor: BECKER GEB KURRAS ANNI
IPC: E05F11/10
Filed: 1974-12-11
Abstract: Fixing of the push rod guide elements of previous designs entailed the provision of through-drilled holes in the window frame, in order to fix the guide element with screw and back plate to the frame wall. The present design uses a single-piece guide element (7) with a cylindrical body, with a lateral bore for the posh rod (2) and a slit extending from the bore to the glass channel side of the frame. The guide element is of plastic and due to the slit is resilient, so that it can be fitted into the hole (9) provided in the frame wall by squeezing it together. On the face of the cylindrical body adjacent to the hole (9) vertical holding extensions keep the body in place.

Patent DE-2503485-A1 (DE)
Title: Air motor of reciprocating piston type - has discharge as well as supply air controlled by regulating valves
IPC: F01B25/00
Filed: 1975-01-29
Abstract: An air motor has a double acting piston reciprocating in a cylinder. Air under pressure is supplied to a pilot valve which admits it alternately to the two ends of the cylinder in order to reverse the piston movement at the end of each stroke. Air is released from the end of the cylinder into which the piston is moving and this release of air is also made through the pilot valve. The pressure of the air supplied to the motor is controlled by a pressure reducing regulating valve. The exhaust air passes through a similar regulating valve between the pilot valve and atmosphere. The introduction of this control on the exhaust reduces uneven running when the motor is under load.
