Patent DE-2345194-A1 (DE)
Title: Electro-magnetic injection valve control - has full-load switch acting on multi-vibrator potentiometer input via second potentiometer
Inventor: SCHUELZKE PETER DIPL-ING
IPC: F02D41/04
Filed: 1973-09-07
Abstract: The arrangement comprises a mono-stable multi-vibrator with an input and an output transistor, which generates square wave switching pulses determining the duration of injection valve opening. The duration of the pulses is speed-dependent and variable by means of a control voltage, which alternates in step with the switching pulses and is fed to a first potentiometer connected to the multi-vibrator input. The switch is connected with the throttle and closes in, or shortly before, the full-load position. One of the switch terminals is connected to common (negative) earth, the other terminal being connected to the tapping of a second potentiometer, which, via a resistor and a diode, is connected to the tapping of the first potentiometer.

Title: Contact copper-plating of steel surfaces - using sulphuric acid, copper sulphate and a surface active agent
Inventor: ANTROPOW LEW I
IPC: C23C18/38
Filed: 1973-09-14
Abstract: In a process for the contact copper-plating of steel surfaces by treating with a soln. of sulphuric acid, copper sulphate and a surface active substance, as the surface active substance there is used a quaternary salt of pyridine and a hydrohalic acid, this being used in the amount required to give uniform deposition of the copper on the surface to be treated. The pref. surface active agent is 2,4-di(methyl-N-pyridine)-methylenesaligenin dichloride (I). The surface active agent is pref. used in an amount of 0.02-3 g/l. In a pref. procedure, the steel surface to be treated is firstly dipped in a solution of the surface active substance and then dipped into a solution contg. sulphuric acid and copper sulphate. The copper plating gives increased electrical conductivity and increased corrosion resistance. The surface active agent retards oxidation and reduction processes on the steel surface, thus enabling corrosion-resistant and strongly adhering copper plating to be applied in a simple manner.

Title: Extruder for plastic material - with endless screw having separate parts for solid and liquid phase processing
Inventor: KIM HEUNG-TAI
IPC: B29C48/03
Filed: 1973-10-20
Abstract: Appts. for treating polymer materials, esp. an extruder has a cylinder, a die, and a rotatable endless screw for displacing the material through the cylinder, and converting it progressively from the solid phase into an extrudable liquid phase. The screw has a first helical groove which exercises a continuous pressure on the moving plastic material and has a constant width so that a constant amount of the moving solid material contacts the cylinder, and a second helical groove for continuously and progressively converting the solid phase into the liquid phase, and contacting the material with the cylinder, the liquid phase being sepd. from the solid phase, and not passing into the latter phase. There is highly efficient conversion of the solid phase into the liquid phase. An entirely plasticised, homogeneous liquid mass is produced and deterioration of the material is a minimum.

Title: Facing wall vertical formwork round windows or doors - using metal with form firmly held by bolting screws
Inventor: HEIMBERG BERND
IPC: E04G13/04
Filed: 1973-12-10
Abstract: No timber wastage occurs, and the verticla formwork can be re-used repeatedly. It is esp. applicable for walling above windows or outside doors, with facing masonry blocks, ensuring a straight and accurate down line, without having to make good the inaccuracies occasioned by wood which has not been cut straight. Light steel tubing is used as support, and U-steel as carriers, and threaded units and firm-holding screws are used instead of wedges, saving a large proportion of the labour usually involved. This can be used for windows and doors of any size.
Patent DE-2403986-A1 (DE)
Title: Superheterodyne reeecceiver for FM signals - has IF amplifier with at least one limiter stage for IF amplitude limiting
Inventor: WELLHAUSEN HEINZ DIPL ING
IPC: H03G3/28
Filed: 1974-01-29
Abstract: The invention enables a receiver for f.m. signals to be constructed in which faulty tuning caused by audible neighbouring stations is not possible. Switching means in the limiter stage deliver, at the beginning of limiting, a first switching signal, and a second switching signal is generated by the i.f. amplitude modulation. Both signals are applied to a logic circuit controlling a switch which switches off the receiver when the a.m. signal is present and the limiting is not operative. An i.f. stage with an amplitude modulator is provided for the second signal generation. It is followed by a band-pass filter which eliminates amplitude variations below the audible range.

Title: Tool holder for reversible cutter bits - are clamped against support faces by screw with upper tapered locking device
Inventor: STAMBLER ABRAM
IPC: B23B27/16
Filed: 1974-03-27

A square cut-out is machined in the end of a tool shank. The rear vertical corner in the cut-out is undercut so that the side faces of the cutter bit will lie against the faces of the cut-out in the shank. The side faces of the cutter bit are jammed against the faces of the cut-out by means of a single screw. The bottom end of the screw hole for this screw is drilled at an angle. The screw has a tapered end, when this tapered end engages with the hole at an angle, the screw will be swung over. The head of the screw which is flush with the cutter bit, will move sideways and jam the cutter bit in position.

Title: Hydraulic drop-forging press - using adjustable hydraulic valve to vary the force of the press-stroke
Inventor: BECHE HANS DIPL ING
IPC: B21J9/12
Filed: 1974-04-23
Abstract: Process for controlling a hydraulic drop-forging press which uses a compressed-air bolster to actuate a driving-piston in a 1st cylinder contg. oil and connected to a 2nd cylinder in which the monkey or ram is housed and which moves upwards to apply forging pressure; between the monkey and the press frame are hydraulic cylinders contg. pistons to charge the press. In order to employ a press stroke of reduced power, valves are incorporated in the hydraulic circuit to reverse the flow of oil under pressure when the driving-piston and/or the monkey has reached an adjustable position in their respective cylinders. The preferred device is a suitable hydraulic control circuit using a multi-way valve. A press stroke of reduced power can be applied, e.g. for bending or upsetting.

Title: Guidance of road vehicles - using induced coil voltages where assymetry generates proportional voltages for use as correcting signal
Inventor: RUBEL ERICH DIPL ING
IPC: G05D1/02
Filed: 1974-09-20
Abstract: A guidance system for road or surface vehicles utilises electromagnetic coils within the vehicles operating together with the electro magnetic field generated by a cable layed within the road surface. The two coil arrangements consist of coupled cross coils (13, 14 and 13' 14') located at fixed heights above the road surface (h1 hz). Any deviation of the vehicle path from the dead centre position over the cable (12) produces an asymmetry in the inducted voltages in the coils. Voltages are generated for vertical and horizontal coils respectively. The derived voltages may be readily used in a correcting control system.

Title: Direct measurement of optical and other quantities - uses sinusoidally modulated light source to determine differences and quotients
Inventor: KROEBEL WERNER PROF DR
IPC: G01N21/31
Filed: 1975-04-23
Abstract: Two or more wavelengths bands are filtered out and passed by mirros and a lens system through the medium, so that their light paths coincide in the medium. After passing through it the two beams are separated by semitransparent mirrors and applied to a light receiver each. Electric signals corresponding to the light flux intensities are applied to the active branch of a two-phase bridge. Their difference voltage is collected from the bridge and superposed on a saw-tooth voltage. Time intervals are derived from the difference voltage zero crossings, corresponding to the quotients of test values, esp. of the difference of attenuation in a medium for two different wavelength bands.
