Title: Improvements in and relating to electro-dynamometers
IPC: G01R5/04
Filed: 1966-04-21
Abstract: 1,112,244. Electric meters. M. BAERMAN. April 21, 1966 [April 24, 1965; June 1, 1965], No. 17519/66. Heading G1Q. [Also in Division F2] In a dynamometer in which a movable voltage coil is mounted inside a fixed current coil, the current coil consists of two oppositely wound half coils and the voltage coil pivots about an axis outside the coil arrangement. In Fig. 1 the voltage coil 7 is carried on an arm 14, counter-balanced at 16, and rotates with a spindle 12. The current coil halves 3, 4 are oppositely wound and each surrounds a respective one of two opposite limbs 8, 9 of the voltage coil. It is established with respect to Fig. 3 (not shown) that the torques exerted by the two half coils 3, 4 on the respective limbs 8, 9 of the voltage coil are additive. Restoring torque may be provided mechanically, e.g. by spiral springs 17, or magnetically. In Fig. 10 each of the fixed half coils has an associated core and these two cores 58, 59 are linked by members 60, 61 which together provide a bridge piece which the moving coil embraces. In this form, opposite limbs of the moving coil move in the air gaps between the bridge piece and the respective cores 58, 59. The additional coils 62 may be energized from an independent A. C. source to eliminate errors due to the remanence of the iron system. A plurality of coil systems, each constituting a single-phase wattmeter, may be mounted for simultaneous rotation about a common axis. Figs. 6 and 9 (not shown) respectively depict sets of three of the Fig. 1 and Fig. 10 movements arranged at 120 degree intervals around a central pivot shaft. Such an arrangement constitutes a three-phase wattmeter. An integrating meter may be provided by causing the dynamometer deflection to vary the radiation or magnetic field acting on an appropriately sensitive electric device, and using an output of this device to control the speed of an electric motor driving a counter. The Specification includes description of a magnetic bearing for the pivot shaft (see Division F2) and of a technique for winding the two half coils 3, 4 of the Fig. 1 form in a single operation from a U-shaped blank Fig. 5 (not shown) stamped from sheet copper.

Abstract: 1,214,702. Polycondensation apparatus. VICKERS-ZIMMER A.G. PLANUNG UND BAU VON INDUSTRIEANLAGEN. 11 April, 1968 [19 May, 1967], No. 17643/68. Heading B1X. A polycondensate, e.g. polyethylene terephthalate, is produced in a rotating, cylindrical drum 1 associated with stationary oblique guide plates 6 which touch the lower internal wall of the rotating drum, the material to be polycondensed being moved from one end of the drum to the other by the ploughing action of the guide blades. The drum is surrounded by a double-walled jacket 4, 5, which is supplied with heating fluid. Alternatively, drum 1 may be heated by electrical radiators. A source to vacuum is connected to sleeve 17. The precondensate is fed into the closed end of the drum through tube 13. The rotation of the drum carries layers of the material upwards and downwards in an approximately circular trajectory, and it is simultaneously moved stepwise to the right by the guide plates. The polycondensate is ejected from the open end 3 of the drum, and removed by screw 16. The guide plates are connected to one another and to the stationary heating jacket 5 by a tube 7 which should preferably be heated so as to heat the plates by conduction. The heating can be made more efficient if the guide plates have double walls and their cavities are connected to the heating space of tube 7. Baffle plates or rotary agitators may be inserted between the guide plates 6.

Abstract: 719,886. Therapeutic substance from amniotic liquid. THOMAS, A. J. P. J., and THIERY, J. P. July 15, 1952 [July 24, 1951; July 3, 1952], No. 17883/52. Class 81(1) A liquid having valuable biological properties is prepared from amniotic liquid by removing suspended solids, deproteinizing at room temperature, - preferably by foaming, passing over an adsorbent until the liquid no longer gives a precipitate with sulphosalicylic acid and sterilizing at room temperature. As shown, amniotic liquid is centrifuged in a turbo filter comprising a covered tank 1 and a centrifuge bowl with vertical walls 2 of a filter material. The centrifugate containing much foam flows into a receiver 7 wherein the foam 8 is destroyed by gas jets 9 and protein scum is removed through the removable lid 12. The deproteinized liquid flows into a vessel 14 in the bottom of which is a layer of absorbent 15 for polypeptides, e.g. active carbon, and then into a collecting tank 17. Prior to filling into, e.g. ampoules, the liquid is passed through a bacteria-proof filter. Alternatively, the sterile liquid may be dried by lyophilization. Foaming may also be brought about by bubbling through the liquid filtered air, nitrogen, carbon dioxide gas or oxygen. Defoaming may be by means of a defoaming agent. The pH of the liquid is maintained at pH 7.0 by the addition of buffers. Sterilization may be by ultra-violet irradiation. Optionally, prior to the adsorbent treatment, the liquid may be subjected to fractional defreezing.
