Abstract: 351,639. Tuning-fork oscillation generators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Ranger, R. H. ; 574, Parker Street, Newark, New Jersey, and Nelson, C. E. ; 347, 83rd Street, Brooklyn, New York, both in U.S.A.) April 23, 1930, No. 12597. Convention date, May 3, 1929. [Class 35.] Pulsating current of constant frequency suitable for use in synchronizing rotating or vibratory apparatus in facsimile telegraph and television systems is produced in a coil 43 by means of a tuning fork 1 or like vibrator driven at its natural frequency by air projected at predetermined intervals against a disc 9 mounted on one tine of the fork. Air under pressure is supplied through a nozzle 17 to a chamber 19 which is made broadly resonant to the natural frequency of the fork by moving the nozzle 17 in or out of the chamber. The latter communicates through an opening 21 with a second chamber 23 which is made broadly resonant to the same frequency by adjustment of a plunger 31. The outlet from the chamber 23 is partially obstructed by the disc 9 which vibrates with the tine 7, a rubber buffer being provided on the latter if required to prevent the disc from touching the chamber 23. The other tine of the fork vibrates between the poles of a magnetic core 41 energized by a permanent magnet 39 and embraced by the pick-up coil 43. A disc 11 and washers 49 are used to balance the tines of the fork. Specification 285,503, [Class 38 (iii), Electric motor control systems &c.], is referred to.

Abstract: 1357010 Fire extinguisher CHUBB FIRE SECURITY Ltd 21 April 1972 [3 May 1971 17 Sept 1971] 12698/71 and 43474/71 Heading A5A A fire extinguisher comprises a flexible tube containing a fire extinguishing liquid under pressure, the tube wall being made of thermoplastic material the external surface of which is exposed throughout its length, the tube thus constituting a continuous detector and exting- uisher along its length, the said pressure and the strength of the tube wall being such that the tube resists the pressure of the liquid at normal ambient temperatures but softens and bursts at any point along its length when said point is subjected to a temperature developed by a fire, thereupon releasing the liquid at that point. The extinguisher may also include a pressure or heat-sensitive isolating device to start an alarm or to switch off the equipment in which the extinguisher is housed (e.g. a television or engine compartment) when the extinguisher operates. A reservoir of fire extinguishing liquid having an outlet connected with an end of the tube may be provided so as to supply the tube with further liquid when the tube has burst at some point. The tube wall may be nylon and the extinguishant may be bromo-chloro-difluoromethane or dibromotetrafluoroethane. A low boiling liquid or inert gas (e.g. N 2 ) may be additionally incorporated to reduce the temperature at which the extinguisher will operate.

The filament 16 is secured to support wires 14, 15 spot welded to the contacts or thimbles 12, 13 which may be formed of chrome iron and are sealed in the bulb 11. The bulb 11 is evacuated through an orifice 17 in the thimble 13, a small quantity of solder, soft melting glass, Khotinsky wax or cement or like fusible material 20 arranged inside or outside thimble 13 being subsequently heated to seal orifice 17. The inside, diameters of the neck portions 21 are made large enough to permit the thimbles 12, 13 to slide freely into position and are fused thereto by heating, pressure being applied to the plastic glass if desired, to effect a tight seal. In another arrangement, Fig. 10, the thimble 13 is first sealed to the lower neck of bulb 11, the filament being attached to the support wire on the thimble 12 and carrying a support wire 15 at its other end. A bead of solder 26 or other conducting fusible material is provided on the wire 15 so that when thimble 12 has been fused to neck 21 and the bulb evacuated the thimble 13 is heated and the bead 26 melts to close orifice 17 and connect wire 15 to thimble 13. Fig. 12 shows a thimble provided with a tongue 28, 29 to eliminate the use of filament support wires. In a further arrangement, Fig. 14, the thimbles 12, 13 are arranged in the bulb 11 with the openings outwards as shown. Thimble 12 is sealed to bulb 11 which is evacuated through the space in neck 21 around thimble 13. The neck 21 may be originally formed as a tube 31 which is used as an exhausting tube and is finally cut or cracked off at the outer end of the thimble. Fig. 16 shows a vacuum chamber 32 exhausted througb tube 35, leads 36 being arranged to supply heating coil 38 which is energized to effect sealing of the orifice in the thimble when evacuation is complete.
