Title: Method of controlling fire
IPC: A62D1/00
Filed: 1969-10-10
Abstract: 1,221,160. Fire fighting with fluid blankets. FACTORY MUTUAL RESEARCH CORP. 10 Oct., 1969 [10 Oct., 1968], No. 50018/69. Heading A5A. The exposed surfaces of objects on fire or under fire risk in an enclosure are subjected to a continuous stream of an ablative fluid from an automatically operable fixed source in an amount sufficient to maintain a coating thickness with ablative properties. An "ablative" fluid is defined as a fluid which, in a layer of sufficient thickness, permits heat transmission from its exposed outer surface but not throughout said layer, the heat instead being absorbed by the layer in converting it into vapour which escapes via the outer surface. Specified fluids are aqueous gels of (i) a crosslinked ethylene/maleic anhydride copolymer (ii) the diammonium-sodium salt thereof and (iii) a cross-linked polyethylene oxide, in an amount 0.1-0.5% by wt. gelling agent in water. The ablative fluid is preferably made on the occurrence of the fire by slurrying powdered gelling agent with a non-hydrolysable, non- reactive water-miscible solvent, e.g. methanol, ethanol or acetone, and injecting the slurry into the fluid carrier. In a test colloidal silica was included in the slurry. The ablative layer should be at least 0.04 in. thick.

Abstract: 985,267. Intercommunication systems. THORN ELECTRONICS Ltd. Dec. 18, 1963, No. 50064/63. Heading H4K. In an intercommunication system in which a number of stations A, B and C are wired in a loop with amplifiers G located at intervals, as required, the loop is closed by a frequency converter V which converts the frequencies at which the transmitters at the stations work into the frequencies at which the receivers at the stations work, thus the gain at any one frequency in the loop is prevented from exceeding unity.

Title: Improvements in process and apparatus for producing particles by ultrasonic agitation
IPC: H01J37/305
Filed: 1964-12-09
Abstract: Uniformly small particles of Fe, Ni, W, Mo, Ta, Al, their alloys, ferrites and compounds, <PICT:1084908/C6-C7/1> resins, plastics, and resinous polymers are produced by ultrasonically vibrating a molten surface of the particle material heated by electron beam irradiation in vacuum apparatus comprising a housing 1, having a cylindrical wall 3 which may be transparent, a vertical or horizontal cylindrical rod 6 of the particle material, a storage rack 9 supporting a plurality of similar rods, mechanism for moving rod 6 down as it is consumed, disposing of unconsumed rod ends and conveying the nexy body 6' to the processing position, an electron beam source and a ceramic or ceramic and stainless steel concentrator horn 21 vibrated ultrasonically by a transducer 20 comprising a magnetostrictive drive energized at 20 Kc/s at an amplitude several times the diameter of the particles to be formed.  He, A, or H2 is introduced through a passage 16 to provide a pressure of 5-12 microns Hg maintained by a pump drawing exhaust gas through a passage 18. Molten material drips on to the horn forming a liquid film from which particles are emitted as a fine spray, collected in a trough 23 terminating in a funnel 24 leading to a cooled container 25 in which a Si oil prevents coalescence.  The electron beam source comprises a hollow cold Mo cathode 10 containing a control electrode 15 and is surrounded by a shield 12. Alternatively a therionic cathode having a beam focusing arrangement may be used with the rod horizontal.  In further modifications the rod itself may be vibrated and the housing may be divided into two parts containing different atmospheres.  If the rod is magnetostrictive i.e. a Ni alloy, nitrided steel or a ferromagnetic material it may be vibrated by an ultrasonic frequency magnetic field or if it is electrically conductive by applying a high frequency current to the rod placed in a strong magnetic field. In other modifications (Fig. 6) material is melted in a crucible 41 subjected to ultrasonic vibration and poured on to a vertical rod 39 vibrating at ultrasonic frequency the bottom of which is heated by an electron beam.  Alternatively the crucible has an extended lip vibrated by a rod and the surface of material at the lip is heated by an electron beam. Smaller or non-spherical particles may be produced by impacting emitted molten or plastic particles respectively on a solid surface or a high velocity jet 51.

Title: Process for preventing decomposition of anhydrous ammonium thiosulfate
IPC: C01B17/64

Abstract: 1,087,796. Automatic control systems. E. BEAUDREY & CIE. Dec. 21, 1964 [Dec. 24, 1963; July 16, 1964], No. 51788/64. Heading G3R. A parameter, such as the pressure drop across a rotating drum or band filter, is kept constant by a system such as that shown, in which deviation from a standard difference in head across a rotary filter 4, measured by movement of a pulley from which is suspended two floats, moves a potentiometer 1 in the control winding circuit of a magnetic amplifier controlling the motor which drives the filter. The control voltage is modified by a second potentiometer 2 whose slide is positioned by a pair of servomotors A, B set in motion by the deviation, either by a third potentiometer 3 or by contacts operated by the pulley. This second potentiometer thus comes to rest when the motor speed has been changed to such new value that the pressure difference across the filter is restored to its original value.

Title: Machine for the continuous manufacture of fibre-containing materials
IPC: B60P1/48
Filed: 1977-12-19
Abstract: A continuous machine for the manufacture of fiber-containing materials such as paper, which comprises a rotating cylinder partly immersed in a body of liquid containing fibers in suspension. The surface of the cylinder comprises permeable and impermeable areas arranged in a predetermined pattern, and fibers are drawn onto the permeable areas by suction from within the cylinder, the layers of fibers formed on these areas being transferred to a conveyor belt which contacts the cylinder surface at a zone out of contact with the liquid. The surface of the cylinder is washed upstream of the transfer zone to remove fibers and other particles which may adhere to the impermeable areas of the cylinder surface by feeding cleansing liquid, such as pure water, across an overflow edge into a space adjacent the cylinder so that the cleansing liquid flows parallel to the impermeable areas.

Abstract: 1,260,763. Weft stop motions. LOEPFE BROS. Ltd. 29 Oct., 1969 [29 Oct., 1968], No. 53023/69. Heading DIE. A weft stop motion comprises a signal transmitter in the shuttle including a thread sensor 10 controlling an active electronic component, a signal receiver outside the shuttle for controlling the means for stopping the loom, and first and second devices located respectively alongside the path of the shuttle and in the shuttle, which devices are not in electrical contact but interact temporarily, during the shuttle movement, to provide electrical energy for the electronic component in the shuttle. The weft sensor comprises a friction plate 10 over which the thread runs, thereby generating an electrical signal in a conductive plate which is transmitted to an amplifying transistor 25 energised by electrical pulses produced when a coil 15 carried by the shuttle passes a stationery permanent magnet 21 carried by the batten and situated inside a coil 17 forming a signal receiver. The signal produced by the action of the weft on the plate 10 is transmitted by coil 15 and picked up by coil 17. Filter 29 separates the part of the signal produced by the thread and filter 34 that due to the supply voltage pulses, and after amplification and pulse shaping, two pulses are fed to a carrier device 36 which only produces an output pulse if both signals are present, indicating the presence of weft. This pulse is fed to a device 37 and cancelled therein by a pulse from a generator 38 actuated by the loom drive mechanism, whereby the stop motion mechanism 40 is not operated. If the weft is broken, no signal is produced by the device 36 and a pulse is emitted by the device 37 to actuate the stop motion mechanism. Separate coils may be provided in the shuttle for generation of supply energy and transmission of signals and the supply energy may alternatively be generated by a beam of light cooperating with a photoelectric device in the shuttle or by an alternating current in an induction coil.
