Title: Photo-electric linear measurement and movement detector - has digital display driven from photodiode arry with moving shutter
Inventor: KREIENSEN KURT
IPC: G01D5/34
Filed: 1975-05-27
Abstract: The photo-electric linear measurement and movement detector consists of an array of photodiodes (16) arranged in a square grid pattern which is fixed to a stationary part of the machinery. A moving shutter is attached to a linkage and exposes or occludes the photosensitive elements in accordance with the linear displacement of the moving part of the machine. The sliding shutter has a sloping edge so that a complete line or part of a line of diodes is exposed or covered at any moment. A square-wave pulse generator (10) is used to scan each line of diodes so that a digital signal is produced which corresponds to the conduction state of each diode. Logic circuits (20) process the scanning signals from the photo-diode raster and a digital counter (30), displays the linear travel.

Title: Stereo tuner low frequency noise suppression - has voltage controlled stage switching to high pass filter mode in presence of noise
Inventor: SAX HERBERT
IPC: H03G5/00
Filed: 1975-08-19
Abstract: Low frequency noise signals in stereo tuners are suppressed by a voltage controlled filter switched into a high pass mode in the presence of low frequency noise. The high frequency stage (1) is coupled to a timing potentiometer (2) and coupled over a demodulator (3) to the switching control stage (5). The switching control stage operates as a voltage controlled high pass filter supplying signals for the output stage (4) couple to the stereo loudspeakers (6). With constant tuning voltage applied (5a) the high pass effect is switched out, thus transmitting normal low frequency signals. When the tuning voltage increases the stage (5) switches to the high pass mode, thus blocking any low-frequency noise.

Title: Telephone with handset cradle - has separate second cradle stay for transmitting calibrated DC pulse signal to exchange
Inventor: RAHMIG GUENTER DIPL ING
IPC: H04M1/08
Filed: 1975-08-23
Abstract: A telephone set has been devised to produce during a call a calibrated d.c. pulse from subscriber to exchange. Production of this pulse requires no additional key and therefore no external alteration on the telephone casing. The removal and deposition of the hand set displaces two separate stays. One stay operates the cradle switch. The second stay is painted a different colour from the first and it can be actuated to transmit to the exchange a calibrated d.c. pulse. This d.c. pulse is independent of the actuating time. This action can be equipped with a time delay for switching on.

Title: Measurement of moisture-content of particulate materials - with automatic compensation for bulk-density variations
Inventor: EIJSVOOGEL WILLEM FREDERIK CAR
IPC: G01N23/12
Filed: 1975-08-26
Abstract: In a process for determining the moisture content of powdered or granular material, in which the dielectric constant of the material is measured, the effect of variations in the bulk density on the measurement of the dielectric constant are compensated for as they occur at the place and time at which the measurement is carried out. The method thus gives results which, because they include compensation for density variation, are more accurate.

Patent DE-2628221-A1 (DE)
Title: Disintegration of wood and annual plants - by process preventing damage to micellar structure, ensuring high quality prod.
IPC: D21C3/22
Filed: 1976-06-23
Abstract: Cellulose, semi-cellulose, wood grindings and woody material generally are obtd. by disintegration of timber, annual plants and similar matter. The fragments, cuttings, etc. of the materials are procesed with(out) prior treatment such as steaming, de-aerating, impregnating, etc. in a direct or an indirectly heated, closed, acid-, pressure-, and heat-resisting vessel equipped with a rapidly rotating worm. Steam, hot water and/or chemical solns. are added whilst the worm rotating rapidly projects the particles strenuously and continuously at high speed against a baffle plate. The forces of the impacts and gravity return the matter into the first windings of the screw, so that the circuit is followed repeatedly. If the process is carried out without chemicals, after the glass transition point has been reached, in a short time the lignin and other accompanying materials are plasticised. Whilst simultaneously, when water or a chemical soln. with a relatively small amt. of fluid is used, after a short time, the cellulosic matter is fully impregnated and the lignin, etc. is dissolved colloidally. The heating of the material against the baffle plate and the mutual friction of the particles, together with the osmotic pressure, release the fibres and fibre bundles by bursting and tearing away the primary wall of fibres. Time, energy and technical equipment can be economised whilst producing undamaged fibres retaining their structure. Beating tools, cone wheels, etc. are only used for hard matter such as knots. When chemicals are used very little fluid is ejected with the prod., so that the liquor to be vapourised contains a large amt. of dry matter.

Title: Hydraulic steering system for fork lift trucks - has tiller steering lever and emergency pump operable by short tiller oscillations
Inventor: HUWENDIEK JOACHIM DR ING
IPC: B62D5/06
Filed: 1976-09-22
Abstract: The hydraulic steering is designed for slow running vehicles e.g. fork lift trucks. The steering has a motorised pump and a hand lever to steer the wheels. The hand lever moves a maximum if 120 degrees left or right hand from the straight ahead position. The steered wheels are returned by a Bowden cable between the servo follower and the steering levers. The hand tiller is connected to the servo follower by a steering shaft surrounded by a protective tube. The servo follower first moves an auxiliary pump piston before displacing the main servo valve. Should the motorised pump fail, short pumping movements on the tiller handle cause the auxiliary pump piston to draw fluid from the container via non return valves and actuate the steering cylinder (33).
