Patent DE-2709260-A1 (DE)
Inventor: KOCH WILHELM ING GRAD
IPC: F16D3/62
Filed: 1977-03-03
Abstract: Newly developed locomotives are equipped with a rotary current short-circuit rotor travel motors which are supplied via converters from the contact line fed with single-phase alternating current. In converters with variable frequency when realised in practice a certain harmonic portion in the motor current, which leads to oscillating moments of the drive motor, cannot be avoided when taking into account complexity. In a drive via a hollow cardan shaft (1) with articulated lever couplings (2, 3) arranged on both sides, these oscillating moments lead to axial vibrations of the cardan shaft. These vibrations are avoided in that in the first (2) of the two centring articulated lever couplings half of the articulated levers (23) are arranged in the direction of the one direction of rotation of the coupling and the other half of the articulated levers (23) are arranged in the opposite direction while in the case of the other coupling (3) all the articulated levers (33) are arranged in the same direction, a specific number of articulated levers being provided. <IMAGE>

Title: Shaft end of central heating circulator - is hexagonal to allow barring tool to rotate shaft without exerting bending moment on it
Inventor: JENSEN POUL DUE
IPC: F04D29/70

Title: Silicon tetra:chloride purificn. to remove silane cpds. - esp. where silane cpds. cause attenuation in quartz optical fibre mfr., by irradiation with light in presence of halogen
Inventor: TAKAMIZAWA MINORU
IPC: C01B33/107
Filed: 1978-02-11
Abstract: Silicon tetrachloride is purified, where the SiCl4 contains a silane (a) as an impurity; and the silane (a) molecule has >=1 H atom directly bonded to its silicone atom. The SiCl4 is purified by irradiation with light in the presence of >=1 halogen, pref. chlorine. The light is pref. rich in UV rays; and irradiation is carried out between room temp. and the b.pt. of SiCl4. The halogen is pref. added to the SiCl4 using at least the molar equiv. of the hydrogen atoms bonded to Si atoms. SiCl4 has many uses, but often contains impurities, e.g. HSiCl3 or H2SiCl2. These impurities are esp. undesirable when mfg. SiO2 glass for optical fibres, because they form-SiOH gps.; and 1 ppm of the hydroxyl gps. in the glass causes an attenuation of ca. 1 db/km of fibre.

Abstract: A constant pressure circuit (II) is fed by a pilot accumulator (1) via a valve (2a) in the constant pressure circuit also feeding another device (H). It can also feed, via a brake distributor (4) on the trailer brake cylinder. A feed valve (2b) is in the constant pressure circuit and controlled by a priority valve. This feeds the pressure deciding the position of the feed valve (2b) according to accumulator pressure. It cuts the supply to other devices in favour of the constant pressure circuit until the accumulator pressure falls to a given pressure.

Title: Fire resistant closure for opening in wall - has slide moving against cutting edge to sever conveyor belt on outbreak of fire
Inventor: RITZ OTTO ING GRAD
IPC: A62C2/18
Filed: 1978-07-22
Abstract: There is a fire-resistant frame parallel to the wall, providing a hollow space between front and rear plates. This forms part of a fire sealing device for a door in a wall with a conveyor device passing through it. There is a fire-resistant slide unit released to move downwards in the event of fire. The slide (3, 4) has an allotted slide passage opening (do, du). At the bottom edge of each frame passage opening (Do, Du), and top edge of each slide opening, there are counter-cutting edges (5, 7; 6, 8), acting in conjunction with opposing cutting plates, for a combined shearing action when the slide moves down. This is suitable for installation in conjunction with continuous conveyor belts, permitting undisturbed conveyor operation but gives reliable closure if fire breaks out.

Patent DE-2847222-A1 (DE)
Inventor: HENTSCHEL MICHAEL DR ING
IPC: H02H6/00
Filed: 1978-10-30
Abstract: In order to produce a charging current, which is proportional to the square of the current drawn by an apparatus or by a machine, for the modelling (18), a clock generator (16) is proposed whose clock pulse width and clock time are proportional to the current drawn. Furthermore, a peripheral circuit (17) for the modelling is proposed which diverts a virtually constant charging current into the modelling (18) during the clock pulses and to earth between successive clock pulses, raises the base point and input of the modelling between the clock pulses and contains a device which corrects a possible change in the output signal of the modelling at the end of each clock pulse and stores the corrected output signal until the start of the next clock pulse. This avoids a complex controllable power source. <IMAGE>
Patent DE-2853428-A1 (DE)
Title: Velvet-loom cutter mechanism - with a rotating circular blade operating on alternate picks
Inventor: GOEBBELS WOLFGANG
IPC: D03D39/18
Filed: 1978-12-11
Abstract: The blade of a pile cutter mechanism for a loom weaving face-to-face pile fabrics consists of a circular or polygonal disc mounted on a carrier whose motion, as it traverses the loom, causes the blade to rotate. A conical whetstone bearing on the rotating blade to maintain its sharpness rotates around an axis which is offset with respect to the axis of the blade. The drive to the blade may be by means of a pinion, or friction-wheel running along a rack or friction-track, or alternatively, a taut belt traversing the loom making a turn around the axle of the blade mounting. The blade achieves a greater depth of cut than traditional knives, allowing cutting to be reduced to once every two picks, thus permitting an increase in weaving speed. Sharpening is continuous and concurrent with the cutting operation, and the rotation of the blade prevents overheating, giving a smoother and more uniform cut.
