Patent DE-2324359-A1 (DE)
Title: Synthetic fibre mesh fabric - using heated rollers to weld inserted wefts to warps at their crossing points
Inventor: BENKER KARL
IPC: D03J1/00
Filed: 1973-05-14
Abstract: Intended partic. for thermoplastic fibres of polypropylene and polyethylene, when the wefts have been inserted into the shed, the matl. passes between the heated rollers, located between the reed and the breast beam, for the heat to give thermal bonding between the warps and the wefts at their crossing points, after which the fabric is cooled by the cold breast beam and a jet of cold air. The purpose is to exploit the thermal welding properties of the synthetic fibres to give a simple bonding process to develop a stable mesh fabric.
Patent DE-2329937-A1 (DE)
Title: Textile machinery light barrier monitor - using light-emitting diode with threshold timer and successive comparator
Inventor: BECHTEL KLAUS
IPC: G01V8/12
Filed: 1973-06-13
Abstract: A light beam barrier for use as monitor against thread breakage or the intrusion of foreign bodies in flyer and knitting looms, warping mills and other textile machinery has a GaAs diode as the transmitter. The intensity of the radiation recorded by a receiver is attenuated by the presence of any foreign body (thread) in the path of the light beam. A threshold timer is thereby switched on for a shorter time. A comparator compares two successive signals and produces an alarm signal in case of non-coincidence. This system responds to very fine threads and to changes of extremely short duration. It is not detrimentally affected by extraneous light.
Patent DE-2332054-A1 (DE)
Title: Hydraulic pipe installation in wet ground - pipe laid in short stretch liquefied by pressurised water
Inventor: HARMSTORF RUDOLF
IPC: E02F5/10
Filed: 1973-06-23
Abstract: Immediately upon leaving the guide channel of the installation machine in the liquefied section of ground the pipe is provided with a covering of underwater concrete i.e. hydraulic cement supplied under pressure through a tube by e.g. a concrete pump so that as the pipe begins to assume its horizontal position, the wet concrete is deposited immediately behind the installation point, and the pipe is eventually completely embedded, assisted by underwater vibrators.
Patent DE-2336818-A1 (DE)
Title: Metal supported rubber sealing ring - inner lip and inclined strips on air side give shaft seal
Inventor: ROUSSEAU JACK
IPC: F16J15/3244
Filed: 1973-07-19
Abstract: Shaft sealing ring with an inner lip which engages on the shaft, has strips on the air side, which are so inclined that the dynamic sealing is ensured through the feedback of the fluid which finds its way to the lip, whilst on its end an active lip part has a static seal forming circular edge. The air side surface has an angle alteration at the end of the strips, which is nearest to the middle of the ring, and which corresponds to a cone with an angle at its peak which is greater than that of the strips, and forms an active lip edge. This in turn leads to the static sealing circular edge, which angle alteration extends over the full height and depth of the strips, whereby the lip is pressed against the shaft by its elastic tension alone. The outer ring-shaped part of the seal is of rubber with inner metallic supports.
Patent DE-2343753-A1 (DE)
Title: Throttle control for manual gear change - with damper to prevent sudden engine speed change and act as shock absorber
Inventor: ANNUSCHIES ARTUR
IPC: B60K26/04
Filed: 1973-08-30
Abstract: The throttle linkage is coupled to a damper which is hydraulic, pneumatic or electric and which retards the rate of drop of engine speed when the foot is lifted off the foot pedal to change gear. In the case of pneumatic dampers the venting hole is covered by a movable cover to enable the driver to set the rate of engine speed drop. The system reduces the gear change shocks on the transmission for inexperienced drivers, and is simple to construct and fit. The damper cylinder is mounted directly above the pedal mechanism, on an extension of the operating rod, and is mounted to pivot.

Title: Through valve with position stop - determines control piston positions and contains spheres in radial bores in sleeve
Inventor: STUERMER JOSEF
IPC: F16K35/04
Filed: 1974-02-15
Abstract: The through valve has a stop, formed by three spring-loaded spheres. The spheres are located in radial bores of a sleeve which surrounds the control piston end. The sleeve is connected to the valve housing. The spheres are loaded by spring elements in the direction of circumferential grooves at the piston end. The elements consist of two spring rings, positioned and supported in a circumferential groove of the sleeve; and of a spring having two coils. The spheres support themselves on additional spheres, loaded by a spring, so that a radially inward directed force acts on the first set of spheres.

Title: Safety control for stability of rotary bucket wheel excavator - has slack and tension cable safety device activated by stress and inclination sensors
Inventor: JUENGEL HEINRICH DIPL ING
IPC: E02F3/26
Filed: 1974-04-05
Abstract: A methoc of safety assurance for the stability of a rotary bucket wheel excavator uses a slack and tension cable safety device which continuously measures both its forces in and inclination of the bucket wheel boom by means of sensor heads and process electrical signals from there to activate cable winder devices. Sensor heads should be placed on the cables such that they are situated near the stress action points for accurate evaluation. The inclination of the boom is determined by an angle which is inclined above the horizontal in an elevated position of the bucket wheel boom and below the horizontal in the lowered position of the boom.

Title: Apparatus for speech analysis and synthesis - applies predictor method with reduced requirement of computer storage
Inventor: WILLIMANN LOUIS-SEPP
IPC: G10L25/00
Filed: 1974-07-24
Abstract: A microphone and analogue-digital converter transform the speech into a sequence of digits using a model of the vocal tract (7). The volume of digits for transmission is reduced by dividing the sequence into successive short lengths, each to be represented by a small set of parameters which will provide the key for the regeneration - - sthesis - of (an approximation to) the original according to a pre-arranged algorithm. An arbitrary set of parameters is used for a first synthesis, the result is compared with the original, a gradient vector is calculated to indicate the best way of applying a small corrective step to the parameters, the corrected parameters are applied to a fresh synthesis, in a series of iterations. At each stage the degree of approximation to the original is calculated (according to some distance function).

Title: Comparative visual display of value of time varying electrical signals - display is on luminescent matrix
Inventor: BIRO FERENC DIPL ING
IPC: G01R13/40
Filed: 1974-07-30
Abstract: The signals, e.g. from two generators G1, G2, are each fed to a corresponding series of amplitude comparators (KS, KO), of which the second inputs are a suitable sequence of reference levels (derived e.g. from tappings on a resistance divider) and of which the outputs of one (KS) control corresponding rows and of the other (KO) corresponding columns of a matrix of light sources. KO feeds the matrix through a series of 'exclusive OR' gates, each gate receiving inputs from the corresponding comparator and from its next lowest neighbour so that only the column representing the instantaneous value of G2 can be excited. The signal from G1, via KS, determines the number of rows excited - that is, the height of the column displayed.
