Title: Gas powder and fluid dispersing device - combines hollow rotor with jet mixer principle
Inventor: GEIGER SIGMUND
IPC: B01F3/04
Filed: 1980-01-24
Abstract: An appliance for use to disperse powder, fluids or gases in another medium, combines the principle of a hollow rotor with that of a jet mixer.

Title: Two piece core for choke held together by snap action - with air gap formed in yoke at point of snap fastening
Inventor: WAASNER BRUNO
IPC: H01F3/10
Filed: 1980-03-06
Abstract: The proposed application of a two part snap together core is to chokes with reduced inductance which is determined by an air gap in the magnetic circuit. The design gives at least 20 per cent reduction in inductance in comparison with a full core of the same cross section. The core has two joints. A full area joint in one core limb (7) is made with an oblique face (9). The second joint is between a yoke section (4) and the other core limb (6). Snap action fastening is provided by overlapping projections (12, 15) on the mating faces. The air gap effect is produced by cutting away part of the yoke section (4) to leave a slot (13). The snap action fastening ensures that the core sections are firmly clamped thus reducing noise due to vibration. The yoke area reduction can be varied to give the required inductance.

Title: Di:chromate removal from chlorate soln. - by redn. with hydrazine and pptn. as chromium hydroxide to avoid toxic gas and filtration problems
Inventor: MAYCOCK KENNETH RAYMOND
IPC: C01G37/00
Filed: 1980-08-26
Abstract: Removal of dichromate (I) from chlorate solns. (II) involves redn of the Cr-VI of (I) to Cr-III with a chemical reducing agent (III) and sepn of the Cr-III in the form of a Cr hydroxide ppte. The novel feature is that hydrazine is used as (III) in a concn. of min 3 mole/mole (I) at min 40 deg C and the pH is adjusted to 7-8 (8) at the end of the reaction. (II) is pref soln of NaCl03 and NaCl obtd by electrolysis of NaCl soln. The Cr hydroxide is oxidised with a conc. (min 2 g/l)NaOCl soln and the (I) obtd is returned to the NaCl soln for (II) prodn. This method avoids the evolution of toxic gases (occurring on redn with Zn(HS)2)and the need for a special filtration stage.

Title: Asynchronous machine with thyristor control and DC braking - has thyristors controlled during braking to provide rectifier bridge supplying DC to stator windings
Inventor: MITTELMEYER HANS DIPL ING
IPC: H02P3/24
Filed: 1980-09-11
Abstract: The machine has the stator windings fed from the 3-phase supply via a rotation or velocity regulator using controlled thyristors. To obtain DC braking selected thyristors are controlled to provide a rectifier circuit for supplying the stator windings with DC, with the current regulator controlling the thyristor firing pulses receiving an input provided by a DC braking regulator. The latter is in turn fed with a signal obtained from the braking force of the machine when acting as an eddy current brake. The braking regulator output signal may be fed to the current regulator via a circuit which provides its square root and a circuit multiplying the root by a factor dependent on the machine velocity or rotation rate. The braking control can be used for a rotary machine or a linear motor.

Title: Double-jointed hinge for large opening angles of doors or the like
Inventor: GRASS ALFRED
IPC: E05D3/06
Filed: 1981-07-28
Abstract: The invention relates to a double-jointed hinge for large opening angles of doors or the like. The object on which the invention is based is to provide a hinge which does not project so far into the furniture space in the lateral direction, no longer offers the possibility of injuries and has a visually more elegant effect, at the same time with a better load-bearing capacity. The solution for achieving the object is that the outer joint is designed as a rack, the toothing of the rack being in operative engagement with a first gearwheel of the gear, and a driven gearwheel of this gear engaging into a fixed rack in the hinge butt, so that, during the opening movement and closing movement of the door, the hinge arm, guided by grooves of the hinge butt, is displaced in a longitudinal direction. The invention avoids articulated levers projecting into the interior of the furniture and intersecting in a scissor-like manner and, as a result of the direct connection of the bowl housing and hinge strap, constitutes a stable articulated system with the least possible countersinking.

Title: Control device for a hydropump
Inventor: ROMETSCH WERNER
IPC: F04B49/08
Filed: 1981-08-21
Abstract: The control device for keeping constant the product of delivery rate and delivery pressure has a single-arm lever (46) on which, with respect to its fulcrum (47), there is applied, via a control valve (31), a moment which depends on the delivery pressure; counter to said moment a countermoment formed by a tension spring (56) is applied. The lever (46) is linked to a follower rod (27) which at all times bears on the servo-piston (21) for the cam ring (16) determining the travel of the pistons. If the abovementioned product is not in equilibrium, the control valve (31) is adjusted by the lever (46) in such a way that, as a result of appropriate setting of the servo-piston (21) and thus of the cam ring (16), the original equilibrium is reestablished. An exact product of delivery pressure and delivery rate is thus achieved at all times, which results, in an appropriate coordinate system, in a precisely hyperbolic course. The control device is of very compact and simple design and thus little prone to faults. <IMAGE>
