Title: Improvements in pyrotechnic devices
Inventor: SCHERMULY ALFRED JAMES
IPC: F42B3/28
Filed: 1962-02-12
Abstract: 1,026,162. Pyrotechnic devices. SCHERMULY Ltd. Feb. 11, 1963, [Feb. 12, 1962], No. 5226/62. Heading F3A. A method of lining the tubular metal casing 1 of a pyrotechnic device comprises inserting into the casing a rolled sheet 5 of water-impermeable synthetic resin material having a width greater than the internal circumference of the casing, allowing the sheet to unroll against the internal surface of the casing, and bonding the overlapping areas of the sheet together. Before inserting the lining a perforated alloy screen 3 is passed through the open end 4 of the casing and abuts an annular flange 2. The sheet 5 has adhesive applied to the surface 6 and has length slightly less than that of the interior of the casing and width approximately twice the internal circumference of the casing, so that when it is pushed through the open end 4 to abut the screen 3 it forms an adhesively secured lining of double thickness. The casing is then filled with pyrotechnic composition, e.g. primer and flare composition. According to the Provisional Specification an alternative method of lining the casing is to dissolve the sheet 5 in a volatile solvent and coat the internal surface of the casing with this solution so that a lining is left when the solvent evaporates.

Title: Improvements in or relating to fans
IPC: F04D25/10
Filed: 1924-03-01
Abstract: 231,301. Cable Accessories Co., Ltd., and Reeves, F. H. March 1, 1924. Mounting.-In an electrically operated fan alternate engagements of a toothed element, operated hv the fan, with two coaxial fixed segments effect a reciprocatory movement of the fan support. The fan blades 1 and an electric motor are mounted upon the spindle 2 supported in bearings 4, 5 in a casing which is in turn suported bv stems 6 in a U-shaped bracket 7. The fan can be rotated in a vertical plane about the stems 6 and can move round a vertical axis owing to the support of the bracket 7 on the pedestal 9. A shaft 11 is mounted in the base of the bracket 7 and is connected by a telescopic flexible drive 15 to a worm wheel 13 driven from the fan spindle 2. At the lower end of the shaft 11 is arranged a pawl 22 on a pivot 23 the pawl being kept in frictional engagement with the end of the shaft by a spring washer. This pawl works between a ratchet wheel 25 and an internally toothed ring 24 both of which are fixed to the pedestal. As the fan motor rotates the shaft 11 also rotates but the pawl 22 can only reciprocate while engaging the ratchet teeth of the wheel 25. The fan and bracket 7 are thus moved round on their support. When the pawl reaches the recess 26 in the ring 24 it can make a partial rotation and then engages the teeth on the ring to move the fan and bracket in the reverse direction. When the pawl reaches the recess 27 in the wheel 25 another reversal takes place. By setting the ring 24 by means of the set-screw 28 the distance between the recesses may be varied to change the angle covered by the movement of the fan. In a modification the pawl is replaced by a pair of toothed wheels 30, 32, Fig. 5 and a smooth oscillatory motion is given to the fan.

Abstract: 1,172,165. Purification of sublimable materials. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 Feb., 1967 [9 Feb., 1966], No. 5583/67. Heading BIB. [Also in Division C1] A sublimable material, e.g. uranium hexafluoride, in the form of vapour which contains gaseous impurities is purified by introducing the vapour through pipe 14 into a cooled chamber 1 which is mounted above an airlock chamber 2 leading down to a sublimation enclosure 3 heated by electrical resistance 13. The walls of chamber 1 are cooled by jacket 4, and the vapours of the sublimable material solidify in the form of crystals on the cooled walls, while the impurities remain in the gaseous state and are discharged through pipe 15. Periodically, the crystals are detached from the walls of chamber 1 by scrapers 7 which are connected to cylinder 5 and moved up or down by a pneumatic motor and a control rod 6. Bellows 9 provide sealing-tightness and allow movement to be transmitted to rod 6. The detached crystals drop into the inlet of airlock chamber 2, which has an upper baffle 10 and a lower baffle 11, the baffle system being rigidly connected to cylinder 5. Baffles 10 and 11 are mutually displaceable by two springs inside the baffle structure (Figures 2 to 5, not shown). The arrangement is such that the crystals enter chamber 2 only when baffle 11 has closed the sublimation enclosure 3; and the crystals drop into enclosure 3 when baffle 10 has closed the chamber 1. The crystals are sublimed in enclosure 3, and the purified vapour leaves the apparatus through pipe 16. Valves (not shown) disposed in pipes 14, 15, 16 enable the pressures inside chamber 1 and enclosure 3 to be controlled. Cylinder 5 has an internal heating device 8 to prevent crystallization on its surface.

Abstract: 817,530. Automatic voltage control systems. STANDARD TELEPHONES & CABLES Ltd. Feb. 24, 1958, No. 5965/58. Class 38 (4). [Also in Group XL (c)] The output level of a valve oscillator is stabilized by an automatic gain control circuit in which a transistor D.C. amplifier is used. The invention is described as applied to the frequency-changer in transmission measuring apparatus, the oscillator of which comprises a pair of valves coupled by tuned circuit 5 and back-coupled via a frequency-determining crystal 9 interconnecting the cathodes. Frequency changing is performed by a voltage doubling circuit comprising rectifiers 14, 15, the signal being applied at terminal 20 and I.F. taken out across resistor 17 in series with rectifier 15. The negative D.C. voltage across resistor 16 in series with rectifier 14 is applied to the emitter of a transistor D.C. amplifier 22 in common base connection. The collector is connected to a negative source 28 via resistor 27, the base being also connected to the source via voltage divider 25, 29. The amplified negative control voltage at the collector is used to control the gain of the valve 1 being applied to the grid via smoothing network 30, 31. The standing current through the frequency-changing rectifiers 14, 15 is monitored by a meter 18 which, with resistor 16, is decoupled by condenser 19. As shown, the transistor 22 is of P-N-P type; the N-P-N type may, however, be used, in which case the polarity of the source 28 is reversed and resistor 10 chosen so that the standing cathode potential of valve 1 is slightly greater than that of the source 28.
