Title: Improvements in or relating to alloys for permanent magnets and to a method of making magnets therefrom
IPC: C21D8/12
Filed: 1934-05-23
Abstract: Permanent magnets are made from iron alloys containing aluminium, nickel, copper, and cobalt, with or without other elements such as chromium, the casting being rapidly cooled from 850-1350 DEG  C., and thereafter hardened at 550-725 DEG  C.  The alloys may contain 5-20 per cent of aluminium, 10-25 per cent of nickel, 1-15 per cent of copper, and 1-20 per cent of cobalt, and may be made by melting together the iron, nickel, and cobalt, and the chromium if any, deoxidizing, adding the copper in small pieces, and finally adding the aluminium.  An example contains 10,1 per cent of aluminium, 16,9 per cent of nickel, 6 per cent of copper, 12,5 per cent of cobalt, and 0,07 per cent of carbon.  The casting may be subjected to the above heat-treatment directly, or may be cooled before being heated to 850-1350 DEG  C.
Patent GB-970223-A (GB)
Title: Improvements in catalyst removal in the manufacture of ª¤-alkylated phenols
Filed: 1963-04-19
Abstract: Ortho-alkylated phenolic compounds are made by reaction of a phenolic compound with an olefin containing from 2 to 8 carbon atoms in the presence of an aluminium phenoxide catalyst, the catalyst being removed by contacting the reaction mass with up to about 6 moles of water per mole of catalyst, sufficient to form an organic liquid phase and a solids phase but insufficient to form a separate aqueous phase, and then recovering the liquid phase, e.g. by filtration or centrifuging. The organic liquid can be sent to distillation for recovery of the orthoalkylated phenols. Alternatively the orthoalkylated phenols may be recovered by direct distillation of the water-treated mass. Examples describe the ortho-alkylation of phenol with isobutylene in the presence of aluminium phenoxide and the removal of the latter.  Other olefines and catalysts are specified.

Title: Improvements in dough-dividing machines
IPC: A21C5/00
Filed: 1949-06-10
Abstract: 667,200. Dough-dividing machines. ENER GEN FOODS, CO., Ltd., and MOORE, E. R. Aug. 25, 1950. [June 10, 1949] No. 15517/49. Class 87(ii). A dough-dividing machine has a rotary cutter 14 of starshaped cross-section and a smooth roller 13 both rotating in the same direction about parallel horizontal axes so spaced that the tip path of the cutter, with as small a working clearance as practicable, lies tangential to the surface of the roller and so disposed that the cutter's teeth approach the roller downwardly. Dough from a hopper 11 is fed by means of a roller 12 and scraper 20 to the space between the cutter 14 and cutter roller 13. This space is subdivided by means of a series of loose blades 21 each having extensions 21b, 21c shaped to fit into and rest on the bottom of grooves provided in the cutter roller and cutter. The roller 13 rotates about twice as fast as the cutter 14 and rolls up the cut pieces before they are stabbed and carried away by pins 22. The pins 22 are mounted in three sets on a shaft 15 which also carries a series of discs 23 each co-operating with a blade 21 to form with it a continuous partition. The pieces of dough are taken off the pins 22 by means of a comb 25 which is oscillated about a pivot 30 by means of a pin and slot mechanism 36, 37. They are delivered onto a knurled roller 18 which is rotated at high speed and throws the pieces tangentially onto a table or a conveyer.

Title: Improvements in or relating to electric protective systems
IPC: H02H1/00
Filed: 1931-05-28
Abstract: 379,355. Protective cut-out systems. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Curtis, R. C. ; 82, North Arlington Avenue, East Orange, New Jersey, U.S.A.) May 28, 1931, No. 15635. Convention date, June 16, 1930. [Class 38 (v).] In a protective system the voltage element of an A.C. relay is supplied through a parallel resonant circuit having in series an external resistance or impedance of a value sufficient to permit the tuned circuit to oscillate and to maintain, for a short period, a predetermined voltage on the voltage-resposive element after the collapse of voltage on the protected circuit, thus ensuring operation of the relay under these conditions. As shown in Fig. 1, a voltage transformer 18 connected across two phases of the line 3 feeds a parallel resonant circuit consisting of a condenser 24 and inductance 25, this circuit including a series-connected resistance or impedance 30. The current through the inductance 25 flows also through the primary winding of a transformer 26 which feeds one or more voltage-responsive relay elements such as the voltage element 21 of a directional relay 9. The current winding 16 of this relay is fed through a current transformer 17 in series with the current coil 13 of an impedance relay 12 the voltage coil 14 of which is fed directly from the transformer 18. To prevent excessive rise in voltage in the voltage coil circuit 28 in case all the voltage elements are disconnected, a resistance 32 is connected across the circuit. The circuit of the tripping coil 6 is completed by contacts 8, 11 of the directional and impedance relays in series. The impedance 30 is of such a value to permit oscillation in the parallel resonance circuit and thus maintain an operating voltage on the coil 21 of the relay 9 for a period sufficient to permit of the relay operation even if the voltage on line 3 practically disappears on a heavy overload. The theoretical principles underlying this action are set forth in the Specification, in which the methods of calculating suitable values of resistance or impedance to be employed according to the invention are demonstrated.

Title: Improvements in or relating to a method of and apparatus for forming striped treatedzones between untreated zones on a sheet of material
IPC: B05B14/10
Filed: 1961-05-01
Abstract: 983,296. Coating surfaces. COMPAGNIA DE SAINT-GOBAIN. May 1, 1961 [April 29, 1960], No. 15739/61. Heading B2B. [Also in Divisions B3 and H2] Striped treated zones are formed between untreated zones on a non-magnetic moving sheet by protecting the zones which are to remain untreated by means of a magnetic mask which under the influence of a magnetic field is maintained stationary but in contact with the moving sheet in a treatment location. In the apparatus shown, a glass sheet I grooved or channelled at 2 is displaced longitudinally by a conveyer roller 3 to a sandblasting chamber 4 beneath which a plurality of masks 10 of, e.g., steel are held in contact with the channels 2 by the field produced by an electromagnet having coils 12 and pole-pieces 11, 11a. By reducing the air pressure in the chamber 4 air drawn in through a slot 9 entrains sand from a hopper 8, and the mixture is directed at a higher velocity by the nozzle 7 on to the sheet and masks, to produce alternate clear and frosted strips. In a modification the apparatus is inverted, seatings being provided to support the masks before the operation. The invention is also applicable to the colouring of, e.g., glass with paint or enamel applied, e.g., by a spray gun and subsequently heat treated.

Patent GB-496896-A (GB)
Title: Improvements in and connected with universal joints and the like
IPC: F16D3/28
Filed: 1937-06-09
Abstract: 496,896. Universal joints. HAMILL. W. W. June 9, 1937, No. 15944. [Class 80 (ii)] In a Hooke's joint of the cross- or ring-type, having rubber orlike bushings 5 for the trunnion-pins 7, means are provided for initially compressing the bushings to a greater extent at their inner and outer peripheral zones than elsewhere, so that whilst anchorage to the adj acent metal parts is ensured, the mid zones of the bushings are sufficiently free to permit the necessary relative movements. In the form shown in Fig. 2, the rubber bushings 5 are an easy push-fit over the tapered trunnions 7 of the intermediate cross-member 1, and are subjected to an initial compression throughout their mass when surrounding split housings 4, carried alternately by shaft-forks 2, are bolted together at 6. Increased initial compression is applied to the inner peripheral zones of the rubber bushings by nuts 8, screwing on the ends of the trunnions 7, and bearing on the bushings through washers 9, having an inner bevelled surface, which in conjunction with a similar re-entrant bevelled surface 10 on a shoulder supporting the other end of the bushing, produces radial as well as axial compression of the bushing at its inner periphery. A similar re-entrant shoulder 14 and bevelled washer 12 produce a like effect at the outer periphery of the bushing. To reduce the " winding-up " action on the rubber when the nut is tightened, the contact-area between the nuts S and washers 9 may be reduced by providing projections on the face of the nut. The bushings 5, pins 7 and housings 4 may also be provided with interengaging longitudinal ribs and grooves 16, 17 which may be undercut. Passages 18 in the cross-member 1 provide for air circulation for cooling. In the form shown in Fig. 3, each bushing 5 is carried in a taper-bored cup 20, slidable in a one-piece housing 4 and forced downwardly, to compress the bushing on the tapered trunnion 7, by a screwed ring 21. Fig. 3 shows the commencement of the compressing operation, completion of which eliminates the vacant space at the base of the cup. Re-entrant bevelled shoulders 19 &c. provide for the increased compression at the inner and outer peripheries. In the form shown in Fig. 6, the intermediate member 1 carries the housings and is in the form of a divided ring, the halves of which are drawn axially together by bolts 6, so as to apply a general initial compression to the rubber bushings 5. The trunnions 7 are carried by alternate shaft-yokes 2, 3. Increased initial compression is separately applied to the inner and outer peripheries of the bushings 5 by rings 8, 26 screwing respectively on the trunnions 7 and in the housings 1, and acting through bevelled washers 9, 12 coacting with re-entrant shoulders at the other ends of the bushings.

Title: Improvements in massage apparatus
IPC: A61H23/04
Filed: 1946-05-27
Abstract: 632,847. Massage appliances. FUCHS, M. May 27, 1946, No. 15980. Convention date, June 7, 1945. [Class 81(ii)] A massage appliance has electrically operated control means actuated by the rhythmic impulses of the heart beats, as shown, means for the transmission of the rhythmic impulses comprises a control collar 4 strapped to a pulsating part of the body. After an initial slight pressure has been given to the compressible fluid, e.g., air or water, in the apparatus by rubber ball 5, the pulsations transmitted through the fluid act on diaphragm 11 causing the pivoted lever 12 to open and close the contacts 13 included in the circuit of an electromagnet 16. The means for the supply of the fluid to the massage collar 2 comprises a pump 24 driven by motor 17 through gear train 19 and slipping coupling 20. The pump 24 is thus alternately brought into and out of operation in the same rythm as the pulse by rotation of the driving shaft 21 being periodically prevented by the locking of the ratchet wheel 22 under the action of electromagnet 16. The speed of the motor 17 is controllable by rheostat 18. Other control means may be (1) contact electrodes or piezo-electric crystals applied to the body in conjunction with a valve amplifier; (2) a pivoted contact lever applied to a pulsating part; (3) a mercury manometer. In an alternative arrangement the pump is replaced by bellows with a return spring and the control collar by a pivoted contact lever. A blowoff valve may be provided between the bellow and the massage collar.
Patent GB-182105-A (GB)
IPC: H01J21/18
Filed: 1922-06-09
Abstract: 182,105. Habann, E. June 24, 1921, [Convention date]. Vacuum tubes.-A negative resistance effect is produced by action or an electrostatic and an electromagnetic field the axes of which are at right-angles to one another and to the axes of the electron path, the electrostatic field being produced mainly or entirely by a constant voltage applied to the electrodes, and the electromagnetic field being produced mainly or entirely by a continuous current, the fields being arranged so that the directions of their deflecting forces are diametrically opposite to each other and are in the plane of the electron path. As shown in Fig. 2, an electrostatic field is produced by a plate 4, mounted parallel with the electron path between a filament cathode 1, and an anode 2, and a magnetic field, perpendicular to the field of the plate 4, is produced by an electromagnet 5. The filament may be surrounded by a grid 3 at a positive potential. In operation, the magnetic field and the electrostatic field due to the plate are balanced, so that the electrons follow a straight path from the filament to the anode. An increase in the velocity of the electrons, due to an increase in the anode voltage, destroys the balance, as the magnetic field has a stronger deflecting action on accelerated electrons, with the result that fewer electrons reach the anode although the anode voltage has been increased, the tube thus acting as a negative resistance. A number of pairs of electrostatic and magnetic fields may be used, and the plate 4 may be arranged outside the tube. The anode and plate 4 may be perforated, or in the form of grids. In one arrangement, Fig. 4, for producing oscillations, an oscillatory circuit 6 and a battery 7 of 200 volts are connected between the filament 1 and the anode 2. The plate 4 is maintained at a potential of 100 volts by a battery 8, and the electromagnet 5 is supplied with a constant current by the filament battery 9. The grid 3 may be kept at a positive potential of 10 to 30 volts. When used for wireless telephony, the circuit of the anode, plate 4, electromagnet, grid,. or of an additional control member may be influenced by speech. This arrangement may be used as an amplifier by replacing the oscillatory circuit 6 by the positive resistance to be counteracted, for instance, a telephone line; the current to be amplified may be connected with the grid 3 or with the additional control member. The tube may also be used as a rectifier of high-frequency current connected with the grid or control member. Specifications 130,400, 180,655 and' 183,879, [Class 40 (v), Wireless signalling &c.], are referred to.
