Title: Improvements in and relating to the heat treatment of sintered metal permanent magnets
IPC: C30B1/08
Filed: 1963-02-15
Abstract: Sintered permanent magnets containing .Co.10-40 .Ni.10-22 .Al.5-14 .Cu.0-10 .Ti.0-10 .Si.0-3 .other elements.0-1 .Fe.balance are heat-treated to produce columnar crystallization by heating them to a temperature which is within 100  DEG C. of the melting point, and then subjecting them to a temperature gradient in the desired direction of crystallization. The gradient may be at least 10  DEG C./cm. and may be achieved by moving the magnets in a direction parallel to the desired crystal orientation from a higher to a lower temperature zone.  Treatment in a magnetic field may follow immediately after recrystallization. Heating of the magnets may be by induction or by electron beam.

Title: Hydraulic servo-motor
IPC: F15B9/10
Filed: 1956-03-01
Abstract: 802,701. Fluid-pressure servomotor-control systems. ALLMANNA SVENSKA ELEKTRISKA A.B. March I, 1956 [March 8, 1955], No. 6417/56. Class 135. An hydraulic servomotor for operating a valve or the like comprises a double - acting piston 2 with equal and opposed pressure surfaces 6, 7, and a co-operating cylinder 1 divided by the piston into two pressure chambers 4, 5 fed from a hydraulic supply 10 through ducts provided with flow-resistances 8, 9, further ducts 12, 13 connecting the chambers 4, 5 with openings 14, 15 in the outer surface of a cylindrical member 11 with which co-operates a sleeve 3. As the sleeve is moved in a direction to close one or other of the sets of openings 14, 15, the piston is moved in a direction to follow the sleeve and re-open the set of openings which has been closed. In the neutral position each set of openings is about half covered. The sleeve 3 is rigidly connected to a coil 22 movable against the action of springs 19 on energization of an electromagnet 23. If the main piston is loaded, the openings 14, 15 are differentially throttled to an extent to counteract the load. In a modification the flowresistances 8, 9 are formed in the piston itself and communicate with an annular groove or chamber therein. Both arrangements substantially eliminate the effects of temperature changes of the servomotor and of fluctuations in the pressure of the hydraulic medium.

Abstract: 739,840. Rotary fluid meters. GENERAL MOTORS CORPORATION. March 5, 1954 [March 26, 1953], No. 6438/54. Class 110 (2). A meter directly measures the mass or weight of fluid flowing per unit of time by a driven impeller, rotating at a constant velocity, imparting momentum to the fluid in directions perpendicular to the direction of flow of the fluid, this momentum being evidenced as a torque applied to a reactor member proportional to the fluid density per unit time. Hollow shafts 20, 22 are rotatably mounted on. fixed shafts 16, 18 and in bearings 24. Impellers 26, 28 with fixed radial vanes are secured to the shafts 20, 22 and rotated in a transparent tube 86 at the same speed in opposite directions by a drive shaft 56 through gears 64, 66; 52, 32; 50, 54 (Fig. 3, not shown) and 30. A reactor 34 with fixed radial vanes is mounted midway between the impellers 26, 28 with one end on a jewelled bearing 36 on the shaft 16 and the other end secured to a rotatable rod 38 passing through a bore in the shaft 18. A pointer 70, passing over an indexed dial 72, is fixed to the rod 38 which is influenced against rotation by a leaf spring 76. The fluid enters and leaves by passages 12, 14 and may flow in either direction. Sealing means 88 may be situated either side of the bearings 24 depending on the effect of the fluid on the bearings. A set screw 78 allows axially adjustment of the shaft 16 and the reactor 34.

Title: Improvements in the production of diketen
IPC: C07D305/12
Filed: 1938-03-04
Abstract: Diketene is produced by passing ketene into liquid diketene and removing the heat of reaction.  The temperature may be above 0 DEG C., up to 50 DEG  C. or over.  Pressure may be employed and a small proportion of a mineral acid or its acetyl compound may be added. The diketene may be contained in a tall cylindrical vessel, ketene in excess being led in to maintain saturation.  Alternatively excess of ketene need not be used if the ketene is led in at the bottom of the vessel which is then provided with baffles so that a saturated solution is maintained at the bottom.  In examples: (1) ketene vapour from liquid ketene is passed into the diketene in a Jena glass cylinder kept at 25 DEG  C. by cooling; (2) 1 per cent of acetyl chloride is used with the diketene and the temperature is 50 DEG  C., a reflux condenser being provided at the top of the cylinder; (3) the process is effected in an autoclave of V2A steel at 10 DEG  C. and 1 atmosphere excess pressure.

Abstract: 1,180,576. Automatic voltage control. WANLASS ELECTRIC CO. Feb. 14, 1967, [Feb. 14, 1966], No. 7039/67. Heading G3R. A voltage regulator comprises A. C. input terminals and output terminals inter-connected by way of asymmetrically conducting means so associated with diodes that current flows through the said means in one direction only regardless of the instantaneous polarity of the A. C. input, the conduction of the said means being automatically varied to correct for variations in the voltage at the output terminals. As shown, a voltage regulator comprises A.C. input terminals 10, 11 which are connected over a diode bridge 12, 13, 14, 15 and an autotransformer T1 to A.C. output terminals 18, 19; a transistor 16 is connected across the D.C. diagonal of the diode bridge so that current passes through it in one direction only, and its conductance is controlled, thereby varying the flow of alternating current through the bridge, in dependence upon output voltage variations, the control signal for transistor 16 being derived from a circuit including a transformer winding 23 cooperating with the winding 17 of autotransformer T1, diodes 24, 25 for rectifying the output from winding 23 to produce a D.C. signal representative of the A. C. output voltage, and a comparator transistor 28 which is associated with a reference Zener diode 28 and which produces the required control signal for application, by way of an amplifier transistor 33, to the base of transistor 16. The transistor 28 is energized by the voltage drop across the transistor 16, which may also have a protective thyristor 21 connected across its collector/emitter circuit. A pair of complementary transistors each associated with an appropriately poled diode may replace the transistor 16 and diodes 12-15 Fig.2 (not shown). The arrangement may be such that the RMS value of the output voltage is maintained constant Fig.3 (not shown). In another embodiment the reference voltage is derived from a sine-wave generator so that the output voltage follows the reference waveform Fig. 4 (not shown), and this embodiment may be used in a D.C. to A.C. converter Fig.6 (not shown). The A. C. output may be rectified so that the arrangement provides a regulated D.C. output Fig. 5 (not shown), and a thyristor may replace the transistor (16, Fig.7, not shown).
