Abstract: 1388956 Drawing sheet glass GLAVERBEL 5 July 1972 [14 July 1971] 31481/72 Heading C1M In a process of manufacturing sheet glass by upwardly drawing a ribbon from a supply of molten glass in a drawing chamber a gas displacing force is exerted periodically across the ribbon path at a position where the ribbon viscosity is between 10<SP>7.6</SP> and 10<SP>13</SP> poises. The forces may be applied in the drawing chamber in an associated annealing shaft. The gas displacing forces may be provided by a pair of gas ejectors 30, 32 (Fig. 2), whose periodic operation is controlled by a device 35 and which are supplied with preheated gas. Alternatively, the annealing shaft may be provided with ports 159, 160, 161, 162 on each side thereof (Fig. 12), closable by shutters 166, 165 controlled by a device 173. Gas is drawn into the annealing shaft through the ports by the convection currents in the annealing shaft and is preheated by burners 174, 175. The gas displacing forces may further be supplied by a pair of propellers 42, 43 (Fig. 4), located one on each side of the ribbon, which propellers are controlled by a device 49 so that only one propeller operates in any period of time.

Title: Method and apparatus for purification of solvent used in the polymerization of olefins
Filed: 1957-10-10
Abstract: Solvent used in the polymerisation of monoolefins and diolefins having an olefinic linkage in the 1-position and which has been separated and recovered from the polymerisation reactor effluent is distilled, the polymer in solution recovered as a bottom product passed to a flash zone, whence the vaporised solvent is returned to the distillation, the polymer recovered from the flash zone, and solvent free from polymer recovered as an overhead product from the distillation.  In a preferred process a portion of the overhead distillation fraction is cooled, condensed, free water removed, part returned as reflux to the distillation, another portion of the condensate, degassed and dehydrated, a portion of the overhead vapours from this step also cooled, condensed, free water removed and returned as reflux to the degassing and dehydrating step, and pure solvent recovered as a bottom product of the degassing and dehydration step.  It is preferred that the olefin is a 1-olefin, e.g. ethylene or butadiene, prepared in the presence of an activated chromium oxide-silica-alumina catalyst in solution in a saturated hydrocarbon solvent.  Apparatus for carrying out the process is described.  Specifications 790,195 and 804,641 are referred to.

Title: Improvements in or relating to electrical stack or layer capacitors
IPC: H01G4/18
Filed: 1969-06-24
Abstract: 1,242,467. Capacitors. SIEMENS A.G. 24 June, 1969 [25 June, 1968], No. 31702/69. Heading H1M. In a capacitor made by dividing up a parent capacitor comprising strips of metallized dielectric material wound on to a drum, the dielectric foils are of shrinkable synthetic resin and the conductivity of the metal coatings is less than 1À5 mho. During division, e.g. by sawing, local heating causes shrinking at the foil edges and the metal coating at the edges is split up into small islands. If the metal is one which undergoes surface oxidation, the islands are insulated from each other. Damage due to flash over is minimized. The dielectric material may be polycarbonate, polyethylene terephthalate or polypropylene.

Title: Dynamic silencing systems
IPC: G10K11/178
Filed: 1970-07-01
Abstract: 1357330 Noise reduction DEFENCE SECRETARY OF STATE FOR 15 July 1971 [1 July 1970] 31795/70 Heading H4J Reduction of sound having one or more prominent frequencies, produced by a source in an enclosure and emitted through an aperture is obtained by picking up a sample of the sound, amplifying the sample and directing the amplified sample sound so that it interferes destructivey with sound from the source in the region of the aperture. Preferably the phase difference between the sound emitted by the source and the amplified sound is between 177 degrees and 183 degrees at the aperture. The sound source may be a generating set, compressor, motor boat engine, hydraulic or pneumatic equipment or a power unit on a fighting vehicle. In a first embodiment an internal combustion engine 2 is situated in a first fork 4 in a duct 20. The sound is picked up by a unidirectional microphone 8 and corresponding electrical signals are passed through an amplifier 12 and phase shifter 14 to a loud-speaker 16 in a second fork 18 of the duct 20. A sound level meter 24 in the aperture 22 of duct 20 is used to adjust the amplifier 12 and phase shifter 14 until minimum noise level is registered. Instead of reducing noise at aperture 22, the noise at aperture 28 may be reduced. Frequencies above 1 KHz may be absorbed by a lining 26 of mineral wool. Preferably the adjustments are made to provide 180 degrees phase shift at the fundamental frequency of the sound source. If a number of frequencies are strongly represented an amplifier, phase shifter and loud-speaker may deal with each frequency separately. An alternative duct 30 (Fig. 2) has two forks 32, 34 and an aperture 35. Fork 32 is connected to a housing (not shown) for an internal combustion engine. A condenser microphone 38 in a chamber 42 through which flows cooling water 44 is set in the wall of the fork. It is connected to an amplifier and phase shifter 40 the output of which is applied to a loud-speaker 46 whose rear is sealed by an enclosure 48. Destructive interference ensures that little sound is emitted from the aperture 35.

Title: Frequency multiplex differential phase modulation signal receiver
IPC: H04L5/06
Filed: 1968-07-05
Abstract: 1,205,658. Digital transmission systems. FUJITSU Ltd. 5 July, 1968 [7 July, 1967], No. 32324/68. Headings H4P and H4R. In an apparatus for demodulating differential phase modulated multiplex carrier signals the incoming signal of each frequency channel is demodulated by a local reference oscillator during one digit period and the resulting signal, proportional to the phase difference between the required frequency channel of the incoming signal and the local oscillator, is used, during the succeeding digit period, to modulate the phase of one output of the local oscillator so that it is suitable for demodulating the incoming signal. Fig. 1 shows a demodulating system in which the incoming signal on line 11, each frequency channel of which comprises two differential phase modulated carriers in quadrature, is applied to two demodulators where the incoming signal is multiplied, in ring modulators 21 and 21<SP>1</SP>, by the output of a reference signal oscillator 20, direct, and by the reference signal in quadrature, derived by phase shifter 19. The resulting signals are integrated over the digit period, in integrators 22 and 22<SP>1</SP>, and the resulting value, dependent on the phase difference between the incoming signal and the reference signal, is stored for the duration of the succeeding digit period in stores 23 and 23<SP>1</SP>. The stored values are used to amplitude modulate, in ring modulators 18 and 18<SP>1</SP> the quadrature outputs of the reference oscillator so that the signal produced by combination of the modulated outputs in 17 is a reference oscillation which, at any time, has the phase of the signal input on the respective frequency channel during the previous digit period. This signal is used to generate a quadrature signal in phase shifter 16 and the two signals in quadrature are used to demodulate the incoming signals in ring modulators 12 and 12<SP>1</SP> and integrators 13 and 13<SP>1</SP>. The demodulated signals are shaped in a limiting amplifier and trigger circuit 14 to produce the required output on line 15. Each frequency channel is provided with a similar arrangement to that shown in Fig. 1 with the local oscillator 20 adjusted to the carrier frequency of that channel. As described the storage of the phase difference signal derived by the integrator 22 in one digit period is obtained by providing two integrators which are used alternately on successive digit periods, one being used to evaluate the phase difference while the other is holding the previously evaluated signal to feed the modulator 18.
