IPC: B65D3/10
Filed: 1945-06-14
Abstract: 614,397. Helically-wound tubular containers. STUART, K. June 14, 1945, No. 15140. [Classes 18 and 66] [Also in Group XXVIII] Tubular containers are formed by helically winding paper or like fibrous material to form the body 30, Fig. 4, which has a continuous thermoplastic lining 33, e.g. of rubber hydrochloride, a closure 34, also with such a lining 36 being applied to one end, and contacting portions of the linings bonded by heat and pressure, as by using a heated iron. The liner is preferably wound first on a mandrel 18, Fig. 5, as an overlapping strip 38 which is fused into a smooth continuous tube by a heated roller 41 under pressure due to its weight and to spring action at 44 during winding but raised as by a centrifugal switch 40 and solenoid 40', &c., when the mandrel strops rotating. Strips of paper or fibre-board are then helically wound and adhesively secured to build the required wall thickness and the composite tube thus formed is cut into lengths. After filling, the top closure is applied and also heatsealed. C-section metal rim strips 28, 29 are then clenched on. In a modification the ends of the body of the container are flanged outwardly to receive flat discs, the liner being heat-sealed and C-section metal strips clenched on.

Abstract: 992,130. Subscription television charging systems. BRITISH TELEMETER HOME VIEWING Ltd. April 18, 1962 [April 18, 1961], No. 15156/62. Heading H4R. In a charging system for a subscription television service the receivers are sequentially interrogated from a central point to determine which receivers are receiving the programme and a record made of the result of the interrogation. Fig. 1 shows a block diagram of such a system in which receivers 14 and 16 are connected via programme enablers 18 and 20 to the programme source 10. Switches 22 and 24 control the programme enablers so that when the switch is closed the programme is available at the receiver. Switches 22A and 24A are ganged respectively to switches 22 and 24 and their condition indicates whether the programme is being received or not. Switches 26 and 28 are operated sequentially by servos 30 and 32 so that the condition of switches 22A and 24A may be sensed sequentially by the detector 40 the output from which is recorded by recorder 42 which is driven synchronously with switches 26 and 28 to make a permanent record of which receivers are utilizing the transmitted programme. Fig. 2 shows one method of accomplishing the sequential switching in which a pulse of the appropriate polarity from the central station over wires 52, 54 operates solenoid 70 to release ratchet wheels 56 which is biased by spring 58 to return until stop 64 is in contact with stop 62; pulses of the opposite polarity over lines 52 and 54 then step on the ratchet and peg 66, arranged at a different position around the ratchet wheel at each receiver, sequentially operate switches 26, 28 &c. to connect the programme indicating switches 22A and 24A to the detector at the central location via lines 50 and 52. In an alternative system the ratchet wheel is replaced by a mains driven clock motor which is held by the armature of a solenoid until a pulse is received when the motor is released and the switch is closed by a cam on the motor shaft after the appropriate period of time. As described this system connects an oscillator to the line if the receiver is reproducing the transmitted programme (Fig. 4, not shown). Also described is a system where if there is a choice of programmes the programme selector switch switches various potentials on to the line dependent on the programme selected. Separate lines may extend from the receivers to a central location where the sequential switching is provided.

Title: Improvements in or relating to the production of uranium compounds
Inventor: MORRIS GEORGE OSWALD
IPC: C01G43/06
Filed: 1943-09-17
Abstract: Uranium tetrafluoride is made by heating an aqueous solution of a uranyl salt with a reducing agent effective in acid solution, e.g. stannous chloride, with a substantial excess of hydrofluoric acid over that required to form the tetrafluoride.  In examples, a solution of uranyl sulphate is prepared by adding tritaoctoxide and the amount of nitric acid necessary to oxidize it to the hexavalent condition to a slight excess of hot sulphuric acid and at least twice the stoichiometric amount of hydrofluoric acid is added along with stannous chloride dihydrate.  Instead of uranyl sulphate, the acetate or chloride may be used, and instead of stannous chloride, granulated zinc may be used.  Specification 696,053 is referred to.

Title: Improvements in superheterodyne receivers for telegraphy and telephony
IPC: H04L27/06
Filed: 1942-11-02
Abstract: 560,880. Superheterodyne circuits for wireless reception. MURPHY RADIO, Ltd., and CULLEN, P. C. Nov. 2, 1942, No. 15388. [Class 40 (v)] In a receiver using A.V.C. for continuous wave telegraphy the intermediate frequency output circuit is formed into a bridge circuit with the beat frequency oscillator across one diagonal and the signal across the other diagonal so that the beat frequency oscillator does not affect the A.V.C. The signal diode with its output load is connected in parallel to one arm of the bridge and is of such high impedance as not to affect the bridge. Fig. 1 shows the output stage 1 of the I.F. amplifier a diode 4 supplying the A.V.C. voltage and the beat frequency oscillator 13 being coupled by transformer 14, 15. The signal diode 16 and load 17 are, as shown, connected across half of the secondary 9 of the output transformer. Alternatively a tuned anode circuit may be used in the output stage and a blocking condenser inserted in the secondary circuit of the transformer feeding the beat frequency oscillation, Fig. 2 (not shown). Fig. 3 shows an arrangement in which the bridge is formed of the output tuning capacitance 18, 19, 20, 21. In a modification the signal diode 16 and load 17 are connected in parallel Fig. 4 (not shown), thus avoiding the necessity to centre tap the output of the I.F. transformer. The use of the capacitance to form the output bridge facilitates tuning by varying the inductance.

Title: Method of and apparatus for balancing rotors
IPC: G01M1/34
Filed: 1942-11-02
Abstract: 568,499. Indicating unbalance of rotors electrically. AKTIEBOLAGET AEROTRANSPORT. Nov. 2, 1942, No. 15405. Convention date, Nov. 1, 1941. [Class 40 (i)] [Also in Group XIX] The magnitude and position of the unbalanced weight of a rotor are determined by driving the rotor at high speed in a test frame so arranged that vibrations arising from the unbalanced condition vary the capacity of an electric condenser to generate alternating potentials responsive to the magnitude of the unbalanced weight, if the angular position of the weight being ascertained by observing the phase relationship between the alternating potentials and a series of potential impulses produced by a light beam reflected from a polished spot on the surface of the rotor. The rotor 1 to be tested is placed in bearings in a frame supported by three springs 6 so arranged that the upper part 7 of the frame can perform a gyratory . motion under the influence of forces arising from the unbalanced condition of the rotor. The rotor is driven by a stream of air projected against vanes 2. The part 7 forms one plate of a condenser, the other plate comprising an arcuate member 9. The condenser is charged by a battery 13 through a resistance 14. The cyclical variation of the distance between the part 7 and the arcuate member 9 causes variation in the condenser capacity. Corresponding current impulses are passed through amplifiers 15, 16, and a filter 18 to one pair of plates of a cathode ray tube 19 to produce the vertical line shown, the amplitude of the impulses being a measure of the extent to which the rotor is unbalanced. Light from a source 20 is reflected from a bright spot or band on the rotor to a photo-electric cell 21, the current therefrom being passed through an amplifier 22 and filter 23 to an impulse producer 24 connected to another pair of plates in the cathode ray tube 19 to produce the horizontal line shown. The phase of the photo-electric cell impulses, indicated by the position of the horizontal line, relative to the end of the vertical line, indicates the position of the unbalanced rotor weight with reference to the bright spot or band on the rotor. The arcuate member 9 can be adjusted angularly by turning a dial 11 to bring the horizontal line on the cathode ray screen to a predetermined position. The reading of the dial will then indicate the position of the unbalanced weight in the rotor. The photo-electric cell may also be connected to a second cathode ray tube 25 to produce horizontal deflections, the vertical deflection being produced by a current supply of known frequency. The pattern on the tube screen will then indicate when the rotor is rotating at a desired speed. The arcuate member 9 may be replaced by two similar concentric members, the part 7 then comprising two concentric parts. The frame carrying the rotor may be arranged so that it can be turned end for end to enable the rotor to be tested upside down.

Title: Improvements in machines for crushing coal, stone and similar materials
IPC: B02C1/04
Filed: 1929-05-21
Abstract: 333,642. Martinez, H., and Kirk, R. H. May 21, 1929. Crushers with vibrating jaws wherein the operative member or members and for the abutment opposed to it or them are so mounted that, in the event of choking or fouling, abnormal resistance is absorbed by one or more springs or other resilient devices are characterized in that the resilient devices are positioned so as to allow the operative member or members and/or the abutment to yield at both the intake and the output end of the machine. The moving jaw comprises two rollers b<1>, b<2>, Fig. 1, mounted on shafts c', c<2>, of which c<2> is resiliently mounted and c' is carried by arms e movable about the axis of the shaft c<2>. The shafts are fixed to levers f<1>, f<2> which are connected together by links f<3> and the levers f<1> are provided with perforated crossheads g through which slide eccentric rods j operated by eccentrics j<2>. The crosshead g is maintained in position by springs m', m<2> and a third spring n encircles a rod n' connected to the crosshead at one end and slidable in a pivoted block n<2> at the other. Rotation of the eccentric j<2> moves the roller b<1> toward and away from a fixed jaw a and so breaks the material entering a hopper h. If the machine becomes choked the rollers move rearwardly either at the upper or lower end or both, the movement of the eccentric merely compressing the springs m<1>, m<2> alternately. The rollers may be separated and a corrugated &c. jaw disposed between them. The springs absorbing abnormal resistance to the operative jaw b may be dispensed with and the stationary jaw a mounted resiliently or the abutment a may be replaced by a jaw operated in the same manner as the jaw b. In Fig. 3, the moving jaw b is connected at the upper end to the eccentric rod j by a link b<3> and at the lower end to a link q<1>, q<2> pivoted at q, the arm q<2> being connected by a link q<3> to the eccentric rod. A rod n<1> is connected to the eccentric rod by a cross-head p and is slidable through a pivoted cross-head n<2>. The link ql, q<2> may be resiliently connected at the ends or the pivot q may be resiliently mounted. The pivot q and cross-head n<2> may be adjustable to vary the position of the moving jaw b. The rod n<1> and cross-head n<2> may be dispensed with by connecting the eccentric rod to one arm of a pivoted bell-crank lever and permitting the link b<3> to slide through the other arm against the compression of a spring surrounding the link. In Fig. 4, the sheave r of the eccentric j' is bored to receive slidable rods g<3> connected together and to the moving jaw b by a crosshead g<2>. Springs m<1>, m<2> are placed on the rods on each side of the sheave r and position the upper end of the jaw b, the lower end of the jaw being connected by a rod n' slidable against the compression of a spring n in a pivoted crosshead n<2>. An adjustable rod s may connect the sheave rand the lower end of the jaw.
