Title: Improvements in or relating to secret telephone systems
Inventor: GILMOUR WILLIAM DUDLEY
IPC: H04K1/00
Filed: 1954-11-18
Abstract: 780,866. Secret transmission. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 10, 1955 [Nov. 18, 1954], No. 33397/54. Class 40 (4). A transmission system is made secret by periodically inverting the phase of the transmitted audio waveform which is synchronously re-inverted at the receiver, phase inversion being achieved by passing the audio wave form through a transformer having a centre-tapped secondary and periodically and alternately taking output from between one or other end of the secondary and the centre tap. The switching between one end or the other of the transformer may be effected by relays but preferably, as shown in Fig. 2, square waves (a) and (b) of Fig. 4, are applied to the grids of switching diodes which in consequence supply a transformer T9 with a periodically phase-inverted wave form. At a receiver square waves (a) and (b) are synchronized by any known means with those at the transmitter to re-invert the wave form. In Fig. 3 pentodes are used to cause phase inversion and comprise balanced gates operated by wave forms (a) and (b) the output being taken from the common anode terminal T8. A variable cathode leg resistance is used to obtain no output when the pentodes are switched in the absence of audio input.

Title: Gumball bank dispensing mechanism
IPC: G07F5/02
Filed: 1975-08-12
Abstract: 1467922 Coin-operated dispensing mechanism P ROSENBERG and M KECES 12 Aug 1975 [5 Sept 1974] 33541/75 Heading G4V A coin-operated article-dispensing machine, e.g. gumball bank 10 comprises coin receiving mechanism 20 which includes a front-plate 34 having a coin-receiving aperture 38, a rotatable coin-receiving element, disc 50, having a pocket 53 for receiving coins, an actuator 22 for rotating the rotatable element, means for preventing reverse rotation of the element past a predetermined position, and means, dog 78, for selectively preventing or permitting forward rotation depending on whether or not a coin is in the pocket 53, characterized in that the means for preventing reverse rotation consists of shoulder 58 on disc 50 and fixed shoulder 82 which is on a back-plate 62. The two plates are held together by heat deformable pins 42, 44, 46, 48, 49. Shoulder 58 projects axially of disc 50 and is formed on a flexible finger-like element 56 at the end of a cam surface 59 thereon. Dog 78 is biased forwardly by a spring 88. If no coin is present clockwise rotation of the disc causes the dog to engage the edge of the pocket which halts rotation. If a coin is present the dog is forced against the spring pressure and rotation of the disc will cause the dog to ride up onto circular rib 61. The disc 50 is rotated through a complete revolution during which time the coin passes to a receiving reservoir. Rotation of actuator 22 causes rotation of spur gear 92 and hence dispensing disc 100. This disc has gumball-delivery apertures 102, 104, 106 which have gumballs directed thereinto when in a receiving position by semi-circular blocking segment 112. The next aperture is positioned at the delivery station when a full rotation of the actuator has been effected. The parts are made of plastics and the pocket 53 can accept coins of different denominations.

Title: Improvements in ice-cream cone forming machines
IPC: A21B5/02
Filed: 1927-12-14
Abstract: 306,644. Antonelli, D. Dec. 14, 1927. Making wafer biscuits. - A machine for making ice-cream cones comprises mould units having halfconical recesses on their external faces, and vertically-displaceable core members, the units being packed into two parallel rows along which they are moved intermittently, and are transferred one by one from one row to the other. As shown, the units 1 are supported by rollers on endless trackways 2, the units being packed together along the parallel straight parts of their course. The cores 5 are carried on core bars 4 connected resiliently by springs 6 to cross-bars 4a having pivoted latch members 7 which engage under projections 8 on the mould units to lock the cores therein. The mould units are locked together by bifurcated levers 10 which engage projections 9 on the units. The transfer of units from one row to the other is effected at both ends of the rows by swinging arms 12a, 12b having pivoted catch levers 13, 14 which engage the end units and move them around the curved parts of the tracks 2. The arms 12<a>, 12<b> are oscillated by crank-operated slides 19, 20 having toothed racks 15<a>, engaging pinions 15 on the shafts carrying the arms 12a, 12<b>. The intermittent movement of the packed units 1 is effected by pawls 33 which engage the heating passages 3 in the units and are mounted on swinging arms 34 connected by spring-returned rods 35 attached to cross-bars 36 of pendulously mounted frames 37 having rollers 37<a> which are engaged by stops 40 on plates 39 mounted on the slides 19, 20, the frames 37 being thereby swung to operate the pawls. The bars 4a are released just prior to the transfer of their units 1 by the latching levers 7 engaging a stop. The freed bars are then lifted by bars 11<b> which engage cam plates 11<c> on the slides, the top of the bars 11<b> engaging the rollers 4<b>. At the same time the pivoted stops 11 are operated by rollers 11<a> on the bars 11<b> and release the locking levers 10, thereby freeing the units for transfer. After the transfer the core bars are lowered by inclined members 22, the latches 7 re-hooking themselves. The levers 10 are forced in to re-lock the units by cam plates 23 on the slides 19, 20 which lift rods 24 and force spring plungers 25 against the levers 10. Butter is supplied, before the core bars are lowered, by swinging nozzle arms which are supplied from a pump operated by the slides 19, 20. The moulds are heated by gas burners 26 supplied from a main pipe 27. A copper heatconducting spindle extends into each core, and the bar 4 is preferably hollow to allow the heat to pass through the bar and around the copper spindles.
Patent GB-477230-A (GB)
Title: Manufacture of sodium hydroxide
IPC: C01D1/20
Filed: 1936-12-09
Abstract: Sodium oxalate is precipitated by reacting a suitable metal oxalate and a soluble sodium salt, e.g. sodium chloride or nitrate, the acid radicle of which forms a soluble calcium salt, in the presence of water and a volatile alkali, e.g. ammonia or trimethylamine.  The metal oxalate must be soluble in the presence of the alkali and the metal must give a soluble compound with the acid radicle of the sodium salt.  Suitable oxalates are those of Cu, Zn, Ni, Ag, Co, and Cd.ALSO:Sodium hydroxide is prepared by reacting, in the presence of water and a volatile alkali, a suitable metal oxalate and a soluble sodium salt, e.g. the chloride or nitrate, the acid radicle of which forms a soluble calcium salt to precipitate sodium oxalate, causticizing this with lime to give sodium hydroxide and a precipitate of calcium oxalate, and reacting this precipitate with the mother liquor from the first stage, after removing at least part of the volatile alkali and adding acid to dissolve soluble constituents of the resulting precipitate, to precipitate the original metal oxalate.  This oxalate must be soluble in the presence of the volatile alkali but less soluble than calcium oxalate, and the metal must yield soluble salts capable of reacting with calcium oxalate and of separation from the alkali to permit recovery thereof, and the compound of the metal and the acid radicle of the sodium salt must be soluble. Suitable metal oxalates include those of Cu, Zn, Ni, Ag, Co and Cd.  In modifications, the precipitated calcium oxalate is added to the mother liquor prior to removal of volatile alkali or the alkali is removed, the resulting precipitate separated, treated with acid, and reacted with the calcium oxalate.  Ammonia is the preferred alkali but other volatile alkalis, e.g. trimethylamine, may be used. The causticizing with lime is preferably carried out in two stages. Removal of volatile alkali may be effected by distillation in steam.

Title: A process for the treatment of synthetic fibres in order to render them suitable for carding
IPC: D06M15/356
Filed: 1954-11-24
Abstract: Polyamide fibres are rendered suitable for carding by treatment with a polymeric substance containing a number of carboxyl or sulphonic groups and, in a second step, with an organic monomeric cation-active substance.  Before the treatment the fibres may be moistened with water, dried, e.g. at 60 DEG C., and further heated, e.g. at 105 DEG C.  The polymeric substance may be polyacrylic acid, polymethacrylic acid, polystyrene sulphonic acid or a copolymer of styrene and maleic acid and may be applied in aqueous solution at a pH between 3 and 4 and temperature between 70 and 95 DEG C.  The fibres may be centrifuged before treatment with the cation-active substance, which may be dodecyl, tetradecyl, hexadecy or octadecyl trimethyl ammonium chloride or dodecyl tetradecyl, hexadecyl or octadecyl pyridinium chloride, triethyl octadecyl hydroxymethyl ammonium chloride, phenyl benzyl dimethyl ammonium chloride, octadecyl hydroxymethyl pyridinium chloride, other corresponding quarternary ammonium halides and the analogous phosphonium, sulphonium or oxonium salts of which dimethyl hexadecyl sulphonium bromide is mentioned.  In the example fibres formed from polymerized epsiloncaprolatam are treated with an aqueous solution of polymethacrylic acid at 90 DEG C. and, after centrifuging, with a solution containing lauryl trimethyl ammonium chloride and oxyethylated stearic acid amide converted into a quaternary compound by dimethyl sulphate, after which the fibres are dried at 60 DEG C.  The reagents may be removed from the fibres with hot solutions of sodium chloride or sodium sulphate or with dilute acids.

A gyroscope rotor is composed of two identical halves axially spaced and rotatably supported on a member extending between them perpendicular to the spin axis and pivotally supported about an axis perpendicular to the spin axis. In the form shown in Fig. 3 a rectangular plate 5 apertured at 15 supports trunnions 6, which may be hollow to accommodate conductors 16, and a bearing member 20 forming the outer race of ball-bearings having inner races 18, separated by a spacer 17 and supporting a spindle 4 carrying'two rotor members each consisting of a cup-shaped member 11 having lightening holes 14 and ventilating holes 12 and carrying a heavy rim member 9 and rotor laminations 30 of hysteresis motors. Flanged tubular members 28 carried on the bearing member 20 support stator laminations 24 and windings 26. The plate 5 may be circular and a single set of windings 26 extend through it to embrace both sets of stator laminations. To the periphery of such a plate may be attached two hemispherical shells to form an envelope filled with inert gas. The stators may be outside the rotors and the eddy current motors may be used instead of hysteresis motors. The directional gyroscope shown in Fig. 4 has rotor halves 44, 45 on either side of a plate 43 supported on an axis 42 in a gymbal 39 supported on an axis 40, rotation about which is transmitted by a gear 38 and a cup-shaped gear 37 to a dial 34. A member 52 sliding on the gymbal 39 carries a finger 54 which by raising the member 52 can be brought adjacent the plate 43 to cage the gyro. This is effected by pressure on a knob 56 transmitted to a projection 58 from a yoke 59 bearing on a plate 60 carrying pins 61 which actuate a yoke 53 and the slide 52. Magnets 46, 47 at the ends of the rotor spindle co-operate with a conducting ring 48 to level the rotor axis. Precession coils 49 co-operate with magnets 50 carried on gymbal 39. A pick-off device 90 may operate a remote indicator. In the gyro vertical shown in Fig. 5 the rotor halves 72, 73 are carried on either side of a plate 74 pivoted about an axis 71 in a yoke 69 in bearings 70. Continuous markings 75, or discontinuous markings 76 co-operate with a reference mark 77, or the plate 74 may carry a scale for the same purpose. a yoke 85 on bearings 86 supports a pendulous member 84 co-operating with one of the end members 82, 83 of the rotor to erect the gyro. The end members are conducting and the pendulous member magnetic or vice versa. Pick-off devices 88, 89 are provided.
