Title: Sound analysis apparatus
IPC: G10L19/02
Filed: 1968-09-10
Abstract: 1,245,414. Speech analysis. INTERNATIONAL BUSINESS MACHINES CORP. 10 Sept., 1968 [14 Sept., 1967], No. 42905/68. Heading G4R. Sound analysing apparatus comprises a plurality of filter systems, each of which has an output of amplitude and phase corresponding to a respective frequency band of an input sound signal, a threshold system for each filter system for determining which filter system output is above a predetermined threshold, and control means for varying this threshold independently of the instantaneous value of an input sound signal. A speech waveform at 1 is split into frequency bands by phase filters 2a-n, each of which produces an output the phase of which depends on the difference between the frequency of the input and the centre frequency of the filter, the outputs being limited at 4a-n and compared in quadrant detectors 6a-n with the original speech waveform limited at 8. Each quadrant detector produces a 2-state output, the upper state occurring when both inputs exceed a threshold. The quadrant detector outputs, after low-pass filtering at 8a-n for averaging, set respective threshold latches 14a-n if they, added to a ramp voltage from ramp generator 12, exceed a threshold. Each threshold latch 14a-n which is set, sets a corresponding formant latch 19a-n, via logic circuitry 16a-n, 17a-n, provided the two adjacent threshold latches (if any) are not set. The number of formant latches set is counted by a counter 22. A predetermined count resets the ramp. A sample clock 10 produces timing signals, the start of each of which permits the ramp to start, and the end of each of which resets the ramp if it has not already been reset by the counter 22. The counter 22 and threshold latches 14a-n are reset at the end of each timing signal.

Title: Anionic polymerization of vinyl aromatic monomers
IPC: C08F4/42
Filed: 1971-04-19
Abstract: 1340722 Polymerization of vinyl aromatic monomers MITSUI TOATSU CHEMICALS Inc 17 Sept 1971 [22 Sept 1970] 43532/71 Heading C3P A vinyl aromatic monomer is polymerized by forming a mixture of the monomer and an organo-alkali metal initiator and initiating polymerization by heating only a limited zone of the mixture to a temperature above 40‹ C. The heat of polymerization in this zone initiates polymerization in surrounding zones and the reaction thus spreads through the whole volume of the mixture. The heat of reaction is thus more readily dissipated than when polymerization is initiated simultaneously throughout the mixture. The intial heating may be brought about by inserting a hot body, e.g. a heater or a piece of hot metal, into the mixture or by injection of a polymerization accelerator such as a Lewis base, when the necessary heat is generated by the polymerization itself. Examples describe the polymerization of styrene, p-methylstyrene or styrene mixed with divinylbenzene in the presence of n-butyl lithium initiated by local heating or injection of tetrahydrofuran.

Abstract: 1,219,133. Glass fibre manufacture. PPG INDUSTRIES Inc. 13 Sept., 1968 [14 Sept., 1967], No. 43569/68. Heading C1M. In the production of glass fibres, molten glass from the refining zone of a glass-melting tank furnace is supplied to a forehearth feeding a plurality of bushings to form a head of glass over the bushings from which fibres are drawn, a substantially constant positive pressure differential being maintained between the atmosphere over the glass in the forehearth and the ambient atmosphere. The molten glass is fed along a canal 16 into two forehearths 18A, 18B. Baffles 32 prevent the furnace atmosphere from the canal entering the forehearths and from one forehearth to another, and are located less than ¢ inch above the glass level. However, the baffles may be platinum coated in which case they extend below the glass level. Each forehearth 18A, 18B has a pressure-sensing device 40 comprising an oil-filled bath 42 into which are partially immersed a pair of bells 44, 46 one of which 44 is connected to the atmosphere of the forehearth and the other is connected to atmosphere external of the forehearth. The difference in air pressure causes a relative movement between the bells which actuates a servomotor 50 which moves a pointer 52 over a calibrated dial 54. The motor 50 is linked to a further servomotor 56 connected to a valve 38A or 38B for controlling damping air flowing from a blower 36 into the exhaust stack 34 of the respective forehearth 18A, 18B. Thus from a given calibrated norm a change in pressure is indicated by movement of pointer 52 and this is corrected by movement of damper 38A, 38B. The forehearths are heated by gas burners located in the roof, the products of combustion exhausting up stack 34. The pressure differential is maintained at from 0À02 to 0À20 inch water column.
