Title: Wide range multiple circuit energy conversion valve - has inlet and outlet stages of unequal constant volume displacement
IPC: F16H43/00
Filed: 1975-11-10
Abstract: The multiple circuit energy conversion vlve for liqs. has seat sleeves and pairs of inlet motors of constant vol. displacement continuously engaged with irregular periphery of the rotors in the valve seat sleeve. The inlet and outlet stages have unequal constant vol. and a wide range of functions are available by the alteration of the friction flow characteristics used e.g. for regulation, testing or modification of the flow, pressure, flow speed and volumetric expansion. The valve arrangement for the input and output of mechanical torques operates with almost unlimited adjustment of the angular arrangement. The system has pairs of continuously engaged outlet rotors (7) of constant vol. displacement. The outer rotors have rotating moment characteristics and volumetric displacements which are unequal with those of the inlet rotors (4).

Title: Capillary electrolytic cell with laminar flow conditions - has grooved counter-electrode with insulating coating, giving high conversion
Inventor: WENDT HARTMUT PROF DR
IPC: C25B1/00
Filed: 1975-12-12
Abstract: Laminar flow conditions are utilised in electrolysis in capillary cells to stop rediffusion of the electrolysis prods. to the counter electrode, allowing reversible electrolysis to be carried out without the use of diaphragms. The counter electrode has grooves covered with an insulating layer to facilitate removal of the gas evolved and, at the same time, prevent reversal of electrolysis by reducing the electrode surface area (by ca. 90%) and thus increasing the current density. High conversions (over 50%) can be obtd. with current yields of 90% even in reversible electrolysis. Conversions of 80% can also be produced at lower current yields of ca. 60%. The grooves can be radial or concentric (with radial connections). Only the bridges act as electrode.

Title: Liquid crystal shutter with electronic actuation - is placed in or behind objective in cameras and has transparent electrodes
Inventor: SEIFERT HELMUT
IPC: G03B9/02
Filed: 1975-12-19
Abstract: The shutter consists of a liquid crystal (1) between two glass plates (2,3) uniformly layered. It has an anode (6) and a cathode (7) connected to a circuit (8). Very high shutter speeds may be achieved, owing to lack of inertia of mechanical moving parts. A control impulse from an electronic circuit is used to make the shutter transparent. A LV impulse may be used. The liquid crystal consists of a liquid quartz composition.
Patent DE-2558093-A1 (DE)
Inventor: ALTENBOKUM KARLHEINZ ING GRAD
IPC: F16H1/28
Filed: 1975-12-19
Abstract: A play-free planetary drive includes a sun gear and an internal gear between which planetary gears revolve as they rotate. The planetary gears are slightly beveled. The sun gear and the internal gear also are beveled, so that the bevel of the sun gear and of the internal gear match that of the planetary gears. With this arrangement of the gears, the sun gear and the internal gear are urged axially against the planetary gears, meshing into them until play has been eliminated. The internal gear is non-rotatably mounted to the housing, but is permitted to shift slightly radially to accommodate radial run-out of the planetary gears. Likewise, the sun gear is permitted to shift slightly radially to accommodate radial run-out of the planetary gears. The radial accommodation thus provided achieves a degree of load equalization among the planetary gears.

Foams have bulk wt. 20-60 (30-50) kg/cm3 and are partic suitable as insulator material. Substitution of urethane-and isocyanurate gp.-contg. polyisocyanates by liquid, homogenous solns. of (II) in (III), improves flameproofness of foams without reducing physical properties, e.g. breaking strength and elongation. Solns. are free from insoluble complexes, have increased NCO-functionality and lower toxicity.

IPC: B23K9/025
Filed: 1976-02-27
Abstract: A T-joint fillet weld is made between two steel plates by horizontal electric welding, using two electrodes with prescribed dias., which are located above and below the joint line, which is in the middle of the space between the two electrodes. The two electrodes are moved alternately, and in prescribed periods of time, towards the joint line, where one electrode is moved at one speed towards the vertical plate, and the other electrode is moved at a slower speed towards the horizontal plate. Submerged arc welding, or CO2 protective gas welding is pref., using one feed roller contg. two different grooves to vary the feed times, the two electrode wires passing through one nozzle. Used for example, in building ships or bridges, to obtain sound fillet welds without an undercut at the top of the weld on the vertical plate.

Title: Spirally wound tube for use as coil core - is formed from several thin paper webs glued together and then spirally wound in place
Inventor: LUHN GERD DIPL ING
IPC: B65D3/22
Filed: 1976-03-02
Abstract: A tube, esp. for use as a core for coiled material, is designed to require less material for its construction and to be lighter in weight without sacrificing strength. This is achieved by using thinner individual strips of paper (5) which are glued together and coiled and then unwound and formed into the required spirals. The glue between the individual strips forms a vapour permeable layer. The individual strips are formed from corrugated paper or offcuts preferably of the quality 130 g/m2. More specifically four strips are glued together. The glue contains filler material e.g. kaolin in order to increase temperature resistance.

Title: Stabilised suspension for twin axled trailer - has opposing trailing arms to prevent bounce on braking
Inventor: KADEN JOACHIM
IPC: B60G5/04
Filed: 1976-03-06
Abstract: The tandem axles of the trailer are linked to the chassis by trailing arms (9, 10) set in opposing directions. During braking one axle tends to depress and the other to rise, to counteract each other and provide a smooth, stable ride. The trailer does not bounce during braking as do conventional designs. Dampers (13, 14) are linked between the trailing arms and the chassis. The suspension is simple to assemble, with the trailing arms anchored on transverse torsion bars set between the axles or on opposite sides of the wheels.

Title: Batched supply system for sealable container - caters for bulk goods having supply flow guided and controlled through pouring angle
Inventor: KANICS ANDRAS DIPL ING
IPC: B65D90/62
Filed: 1976-12-20
Abstract: Method providing batched supply to a container of pourable bulkgoods, slow flowing deposits, slurry or silt is for a container to be sealed tight after the batch has been supplied through an inlet opening in it's top wall. The supply flow is guided to a closure element of the container ensuring a sealing closure of the inlet opening. During the first stage of the opening process the flow is guided on to a smaller surface in relation to the surface area enclosed by the sealing seat in accordance with the pouring or the flow angle. During the subsequent stage of the opening process the material is heaped until reaching a pre-determined height level. It is then permitted to slide freely along the side contour line of the edge of the sealing surface.

Title: Torque measurement system for power or electrical machine - uses strain gauges fixed to shaft and telemeter to pass signals to indicating instrument
Inventor: KRON AUGUST-WILHELM DR ING
IPC: G01L3/10
Filed: 1976-12-21
Abstract: Torque measurement system consists of strain gauges (21) mounted around a rotating shaft or coupling (11, 14). The strain gauges are fixed at 45 deg. to the shaft axis in bridge circuit formation so that their movement gives a summing signal proportional to the torque on the shaft.

The component power source is a dry battery, a.c operated pick-up (23) or induction coil where the shaft is attached to an electric motor. The transmitted signal is passed via a receiver to a demodulator and an evaluation circuit. The output is indicated as torque and temp. The h.f transmitter voltage is modulated with a signal proportional to the measured value.
