Patent DE-2807401-A1 (DE)
Title: Start-pulse synchronised oscillator - has piezoelectric crystal with electrode pairs coupled to amplifier and to supply switch controlled by start pulses
Inventor: SCHUMACHER HELMUT DIPL ING
IPC: H03L3/00
Filed: 1978-02-21
Abstract: The oscillator has a piezoelectric crystal (PK) connected by a first electrode (B1) on one side, via a resistor to one supply pole (U1) and by a second electrode (B1) on the opposite side via a transistor switch (T1) to the other supply pole. The transistor switch is controlled by the start pulses. The two inputs to the oscillator's amplifier (V1) are each connected to two further electrodes (B2) on opposite sides of the crystal. The piezoelectric crystal consists of quartz or a ceramic. A feedback path (R) may connect the amplifier's output to the first electrode.

Title: Fuel injected IC engine - has second fuel buffer cylinder to facilitate starting by reducing changes in vol.
Inventor: SCHMUCK ERWIN
IPC: F02M69/46
Filed: 1978-04-24
Abstract: A pump delivers fuel from a tank through a spring loaded buffer cylinder and a filter to a metering valve. The valve has a piston moved by a lever from an air flow measuring plate in the engine suction upstream of the throttle. The lever moves the piston against a return force provided by the fuel. This fuel comes from the main supply through a brance within the valve with a decoupling throttle. The return from this branch to the tank has a second spring loaded buffer cylinder connected to it. It reaches the tank through a sensitive valve.

Title: Dynamo with rotating stator and rotor - has coupling system using gears, and brushes pass pulsating current through armature and excitation windings
Inventor: FIACCO SEBASTIAN J
IPC: H02K23/60
Filed: 1978-09-14
Abstract: The stator carries excitation windings and brushes for the commutator. The rotor (24) and stator (32) are coupled through gears with a specified speed ratio, so that they can rotate relative to each other. The brushes collect a pulsating current whose frequency is determined by the relative speed of the stator and rotor, and pass it in series through the armature and excitation winding (38). The gearing can be arranged to rotate the rotor and stator in opposite directions to give a high relative speed without excessive rotational speed.

Title: Spray printing device for bar chart codings - has pulsed pump which delivers fluid onto spinning disc for discharge onto printing strip
Inventor: SCHMID HANS A DR
IPC: G06K1/12
Filed: 1979-02-02
Abstract: The spray printing of bar chart codings of the type used for article identification systems, uses a pulse controlled pump system. A high speed motor (10,000 r.p.m. plus) is used to spin a cup shaped rotor (1) that is vertically mounted in a closed housing (4). Printing ink is directed in a jet (31) at an angle to the disc, from a nozzle and a pump (3) of the fuel injection type. The ink is spun off the edge of the disc and emerges through a square shaped window (5) and is deposited on the printing strip (6) moving at a controlled rate. The size and definition of the bar chart code markings is determined by the movement of the strip and the pulse activation signal for the supply pump.

Title: Enhanced sensitivity of thin layer chromatography fluorimetric measure - using mirror glass sepn. layer substrate
Inventor: ECKERT THEODOR PROF DR
IPC: G01N21/64
Filed: 1979-03-15
Abstract: Sensitivity of fluorimetric measurements of substances following thin layer chromatographic sepn., esp. High Performance Thin Layer Chromatography, involves the use of mirror glass instead of the conventional ordinary glass with mirrored surfaced as a substrate for the sepg. thin layer material. The thin sepn. layer is attached to the mirror glass. The sensitivity increase is partly dependent on reflection back of fluorescent light not radiated downwards tending to increase capture efficiency. Excitation light failing to produce fluorescence is reflected and passed through the thin layer plate again. In this way the amt. of fluorescence stimulated is additively increased.

Patent DE-2917682-A1 (DE)
Title: Shearing and welting machine for footwear soles - has shearing fingers holding turned in heel and instep edge on last for sticking down welt
Inventor: WINTER GERHARD ING GRAD
IPC: A43D21/12
Filed: 1979-05-02
Abstract: In the machine, the base of the last points upwards as the last (1) is held on the socket holder (2). At the beginning of the adhesive application the two adhesive nozzles (31) are at a point and press the welt (30) firmly on the last. The nozzles (31) then move along the last edge towards the shoe toe. When they reach a point the shearing-in fingers used for the arch area are introduced and are controlled so that they carry out the shearing movement individually or in groups one after the other. When the adhesive nozzles have reached a point they are removed and the shearing fingers move in. The welt can thus no longer be sprung back into a position (30') because it is pressed by the fingers on to the last. The thermoplastic adhesive need not be applied extremely hot since it is used for sticking immediately after its application.

Title: Magnetic core construction with e=shaped laminations - which are alternately inserted inserted into core from opposite sides with corresponding yoke limbs alternately added
Inventor: SCHMIDBAUER IGNAZ GEORG
IPC: H01F41/02
Filed: 1979-11-21
Abstract: In the production of a magnetic core of sheet iron laminations, the core having two yokes and three parallel arms joining the yokes, the laminations are stamped from sheet iron to form pairs of laminations of, for example an E and I (7,8) lamination. The laminations are then mechanically stacked by inserting the central limb (6) of the E into the coil core from one side and then abutting the I at the second side. A second E is then inserted at the second side and its I abutted at the first side, stacking continuing with alternate E's and I's from the same core sides. Variations on the lengths of the E limbs may be effected to provide e.g. a double E or T, U; E, L or E, F laminations.

Patent DE-3011559-A1 (DE)
Title: Hot moulding of resin impregnated fibrous mat - after preheating by high frequency electrical field
Inventor: ZEMPEL KONRAD
IPC: B29C35/12
Filed: 1980-03-26
Abstract: A method of making a moulding from a resin-impregnated, flat fibre mat, esp. a cotton non-woven impregnated with phenolic resin, uses a heated mould. Before the fibre mat is laid in the mould, it is subjected to a high-frequency electrical alternating field. The method is intended for production of mouldings for the internal fittings and furnishings of automobiles, where hot mould temperatures of 180-220 deg.C and moulding periods of 2.5-3 minutes are common. The low thermal conductivity of such a fibrous mat makes it difficult to heat it uniformly throughout in a hot mould within a reasonable period. By passing a high-frequency alternating electrical current through it, however, the interior becomes heated and builds up a store of heat so that the time required in the mould to obtain a fairly uniform temperature throughout can be reduced by as much as 50%.
