Title: Obtaining the temp. profile of a coke oven battery heating flue - by lowering in a cooled tube contg. a radiation pyrometer
Inventor: KOVACIC JOSEPH EDWARD
IPC: C10B21/00
Filed: 1975-02-05

Patent DE-2537381-A1 (DE)
Title: Vertical prefabricated concrete beam connection - involves inward and downward slope absorbing vertical bearing pressure and horizontal tensile force
Inventor: WALLERICH GISBERG DIPL ING
IPC: E04B1/21
Filed: 1975-08-22
Abstract: The connection to be provided is between two vertically aligned prefabricated beam or slab beam elements, made of reinforced or stressed concrete. It prevents the occurrence of torsional moments resulting from an off-centre joint obviating the need to enlarge the elements to a degree intolerable for storey ceiling height dimensions in high-rise buildings. The accommodating beam element (1) is shaped with an inwards and downwards slope (3). This absorbs the vertically effective bearing pressure of the beam element, and at the same time the horizontally effective tensile force resulting from the off-centre attachment.
Patent DE-2551486-A1 (DE)
Title: Sail boat rope clamp with pivoted grooved jaws - having wedge faces with diverging grooves to open jaws when rope vertically inserted
IPC: B63B21/08

Each wedge face has parallel grooves (10) whose sides form surfaces on which the rope can slide with little resistance. The grooves (10) of the two jaws diverge such that, when the rope is pressed-in in vertical direction, the jaws tend to open without the rope being moved in axial direction.
Patent DE-2600783-A1 (DE)
Title: Liquid dispersing device - uses low power input and gives high pressure delivery
Inventor: WIEDMANN WERNER DIPL ING
IPC: B01F25/74
Filed: 1976-01-10
Abstract: Dispersion machine has a rotor with passages running from inside to outside inclined at angle in the opposite direction to that of rotation. Surrounding this is a stator element which forms a narrow gap between the stator and the rotor, this causing shearing in the liq. ejected from the rotor. The rotor passages are straight and of uniform cross section. The radial thickness of the rotor ring and the inclination of the passages are selected so that on the inner side there is a smaller angle and on the outside a larger angle between the passages and a tangent to the inner and outer circumferences of the rotor. The ratio of inner to outer dias. of the rotor should not be 0.15, and pref. be 0.5-0.58 at most. The system described uses relatively low power input, gives a high pressure delivery and produces a good dispersion with high efficiency.
Patent DE-2602604-A1 (DE)
Title: Fluorescent discharge tube ignition system - has generator with intermittent oscillating output of low frequency during half period intervals
Inventor: KANEDA ISAO
IPC: H05B41/18
Filed: 1976-01-24
Abstract: Ignition system for a discharge tube, which retains the ignition by means of an intermittent voltage chasing generator, which supplies reignition energy to the discharge tube during each half period of the alternating current supply source. The ignition system can be used for a combination of one or more discharge tubes. There is a current limiter connected to the discharge tube used for limiting and stabilising the current to the tube. The chasing voltage generator circuit which produces an intermittent oscillating output is coupled to the discharge tube or tubes via a coupler with an intermittent oscillating output. The alternating voltage source supplies a low frequency output component with a blank interval during each half period which is supplied to the discharge tube elements. The voltage generator produces a high frequency output component which is fed to the chasing voltage generator circuit.

Title: Railway track force locked elastic rail fixture - has clamp bracing unit lying on rail foot in rounding radius area
Inventor: HEIM ARNIN DIPL ING
IPC: E01B9/48
Filed: 1976-05-28
Abstract: The force-locking and elastic railway track rail fixture, with high distortion resistance, involves ribbed plates and clamps. The bracing component (11) on the clamp (9) is brought to rest on the rail foot (4), with linear contact (13), at an interval from the transition line (8) between the foot cover surface and the rounded radius (6), but in the area of this radius. The rail foot overlaps further in the direction of the rail stem, with the interval maintained. The cross-sectional profile of the bracing component can incorporate a cantilevered arm (18) directed towards the ribbed plate (10) in the area overlapping the rounded radius of the rail foot. Resistance to distortion is enhanced, and the system can be applied to inside stock rail bracing or inside track rail bracing.

Title: Two-channel hearing aid system - has HF and LF channels, each containing input filter and AGC amplifier and output filter
Inventor: EGGERT ALBERT
IPC: H04R25/00
Filed: 1976-09-16
Abstract: The hearing-aid has two channels (3, 4) between a microphone (1) and a loudspeaker (21). One channel handles the upper part of the wanted band and the other the lower part. Each channel consist of an input filter (LP or HP), a gain-controlled amplifier (6) and a filter (7, 8) with the same cutoff frequency as the input filter of that channel. The amplifier output is passed via a potentiometer (10) and a second amplifier (11) (followed by a rectifier) to its own gain control input. The advantage lies in each producing output signals of the wanted sub-bandwidth.

Title: Closure for vein cannula - has self-acting cut=off valve which opens when injection tube is inserted
Inventor: ZIMMERMANN KURT DR
IPC: A61M39/26
Filed: 1976-11-16
Abstract: A closure for a cannula, indwelling cannula or catheter contains an automatic cut-off valve, and is made with a connection socket on the reverse side. The valve is made as a V-shaped piece of plastic, with one semi-rigid and one elastic limb. The elastic limb carries a hemisphere which, when the connector is not in use, closes the exit fromt he cannula. When an injection or blood-sampling instruments is inserted into the connector, the V-shaped piece is shifted, bending the elastic limb and bringing a channel in the hemisphere opposite the cannula exit, thus opening the valve. When the instrument is withdrawn, the elastic limb straightens, and the valve closes again.
