Title: Improvements in or relating to alternating frequency generators
IPC: H02P9/42
Filed: 1959-09-11
Abstract: 901,781. Amplifiers. CANADIAN WESTINGHOUSE CO. Ltd. Sept. 11, 1959 [Nov. 5, 1958], No. 31019/59. Class 40 (9). An amplifier or generator comprises an alternating current generator with a toothed rotor 4 and a reactor 3 excited by the signal from source 1. The output from the reactor 3 is rectified by a rotary switch 6 running in synchronism with the rotor 4, the rectified output being fed to terminals 12, 13. Filters 2 and 5, respectively, pass and reject the frequency of the signal from 1. In a modification, Fig. 1A, transistors are used instead of a mechanical switch. A signal applied to terminals 14 controls the output of the centre-tapped winding 18 of alternator 15. Alternator 24, which is mechanically linked to alternator 15, is excited by winding 26 and controls transistors 19 to 22 in series with secondary windings 28 to 31 to give full-wave rectification. The output is fed to the load 33. A voltage reference 34, Fig. 4, may feed the generator 36 through a variablegain amplifier 35. A feed-back may be taken from the input to the load 37. The feed-back is compared with the voltage reference 34 in a comparator 39, the amplifier 35 being controlled thereby to correct any error. To give a smooth output, two amplifier generators of the kind shown in Fig. 1a may be connected with their outputs in series and 90 degrees out of phase.

Title: Improvements in or relating to rotative wing aircraft
IPC: B64C27/54
Filed: 1933-11-09
Abstract: 428,231. Rotative - wing systems. COATS, A. G., Gloucester House, Park Lane, London, and HAFNER, R., 47, Mantlergasse, Vienna. Nov. 9, 1933, No. 31300. [Class 4] In a rotative-wing system having flapping blades and means for varying or reversing the angle or pitch either differentially or as a whole, the blades are loaded or have their centre of mass toward their outer extremities so as to give them a large radius of gyration and which are provided with a section having a good lift drag ratio and a low resistance when at zero or small inclination. As shown, the rotary blade 1 is suspended against centrifugal force from a rotating hub 2 by a torsionally flexible member 3, Fig. 2. The pitch of the blades may be varied differentially or as a whole by means of a spider 4, Fig. 1, mounted on a ball joint 6 on the hub 2. The spider operates upon the ends of radial arms 7 fixed to the roots 1<a> of the blades 1. A shaft 5 formed with the ball joint 6 is controlled from the cockpit by an irreversible control lever 8 connected at 9 to the body of the machine. Each blade is provided with a central tubular member concentric with the axis Y-Y, Fig. 2, of the blade formed of two tubes 10, 11 connected by a member 12 which is directly attached to the hub 2 by the flexible member 3. The tube 10 is light in weight and the tube 11 heavy. The forward portion of the blade 13, Figs. 5, 6, may be formed of heavy wood to balance the larger portion of the section behind the spar and weights may be placed in the bolt holes 20. Ribs 17 are glued to the rear portion 14 and the outer ends of the ribs are connected by a trailing edge 18 and the skeleton section so formed is covered with plywood 19. The members forming the connection 12 may be screwed together. The blades may have a stable cross-section such as N.60.R and the masses of the blades along their length may be proportional to an amount which lies between a value proportional to the chord and a value proportional to the product of the chord and radius from the main axis in order to obtain minimum bending stresses during rotation. In taking off, the pitch of the blades is adjusted for no lift and the blades rotated to about 40 per cent above their normal speed. The pitch control is then altered to make use of the stored kinetic energy to give a helicopter effect lasting about five seconds. The propeller is then put into gear with the engine to enable the machine to acquire speed and fly as a windmill plane. Specifications 385,101, 418,212, 418,674, 418,698, and 426,197 are referred to.

Abstract: 1299815 Electrically heated food. warming trays R F LAX 5 July 1971 [14 Aug 1970] 31401/71 Heading H2H [Also in Division H5] A device 22, Fig. 1 for keeping food warm comprises a hot-plate 24 whose lower surfaces is covered by electrically resistive heating tapes 76, Fig. 5 which are connected to rechargeable Ni-Cd batteries 44 by means of a switching circuit. Which automatically disconnects them again when the battery voltage falls below a predetermined level. The batteries and circuit are arranged in a housing below the plate and the tapes (Figs. 2-4, not shown) and are separated therefrom by thermal insulation blocks. The device is operated manually by switches 78-82 and buttons 84-88. When the device is to be used, switch 78 is moved to HEAT, switch 82 to ON, and button 84 is pressed so that transistor 122 is rendered non- conducting which in turn renders further transistors 134, 136 conducting to energize a relay 118. Contacts 116 are thereby closed: one (154) of these energizes a relay 124 to close further contacts 122 so that strips 76 (and a lamp 86) are connected to the batteries. When the battery output voltage falls below an acceptable level the above process is operated in reverse, transistor 122 being rendered con-     ducting. The batteries may be provided as a plug-in pack which can be inserted in the housing, and the device may be constructed in the form of a portable heating cabinet.

Title: Improvements in or relating to waveguides for conveying electromagnetic energy at ultra-high frequencies
IPC: H01P1/17
Filed: 1945-11-23
Abstract: 604,076. Wave-guides. WILD, E., and WRIGHT, C. S. Nov. 23, 1945, No. 31630. [Class 40 (viii)] A circular wave-guide has a pair of conducting bars extending longitudinally of the guide and projecting into the guide from the inner surface and located diametrically opposite one another in such positions as to modify the phase velocity of a propagated wave in a plane which is inclined to the plane of polarisation of the transmitted wave. As shown, a circular wave-guide section 3 has diametrically opposed metal bars 2 lying in a plane which is at an angle of 45 degrees to the plane of the transverse electric field of the transmitted wave. The bars 2 are of such length that the electric component in the same plane is retarded in phase by 90 degrees relative to the electric component at right angles to the plane. This produces a circularly polarised wave at the output of guide 3. Metal studs 6.are provided for impedance matching. Guide 3 leads to a second guide 4 in which the bars 2 are of sufficient length to produce a further 180 degrees phase shift,. thus reversing the sense of the circular polarisation. A final section 5 produces a further 90 degrees phase shift, thus converting the wave back into a plane polarised wave. This arrangement allows of the continuous phase adjustment of a wave passing through the complete guide by rotation of the central section- 4 about its longitudinal axis.

Title: Improvements in and relating to orthopaedic bandages and the manufacture thereof
Inventor: JONES BERNARD MALCOLM
IPC: A61L15/08
Filed: 1957-10-10
Abstract: A cast-forming surgical bandage comprises a fabric coated with a free acid copolymer resin of vinyl acetate and crotonic acid or a derivative thereof.  Gauze or knitted fabric is coated or impregnated with the copolymer in ammonia solution, acetone or a volatile amine, e.g. methylamine, dimethylamine, trimethylamine or ethylamine, which converts the copolymer into a water-soluble salt.  On drying, the salt is restored to the copolymer form and hardens.  Before use, the bandage is immersed in ammonia solution or a volatile amine to produce a water-soluble salt of the copolymer and thus soften the bandage, which when subsequently dried is in the hardened copolymer form.  Alternatively, a water-soluble salt of the copolymer is formed by treatment with a non-volatile base, e.g. sodium carbonate, the copolymer being hardened by magnesium or aluminium sulphate which forms a water-insoluble salt.  The bandage may additionally have a plaster of Paris layer or 10-90% of plaster of Paris by weight of the coating composition may be added to the copolymer as a filler.
