Filed: 1967-12-21
Abstract: 1,205,776. Stripping volatile substances from polymer latices and other fluid materials. PARKSON INDUSTRIAL EQUIPMENT CO. 21 Dec., 1967 [20 March, 1967], No. 58139/67. Heading BIB. [Also in Division F1] Volatile substances are stripped from a polymer latex, a slurry or other fluid material by pumping it through line 26 into a stream of vapour, e.g. steam, flowing through venturitube 28, passing the suspension of: dispersed particles of material in steam through.a tortuous path formed by a pack 40 of alternate plates and gaskets' where the suspension expands and the particles are fractured by impact against surfaces, and then passing the suspension to separator 50 where the steam, containing the volatilized substances, is separated from the particles of stripped material. The stripped 'material, withdrawn from the separator by pump 56, may be submitted to a second treatment, if required. The steam passes from separator 50 to condenser 62, and the condensate is withdrawn by pump 64. The system is operated under vacuum by means of two-stage steam ejector 66. The temperature and pressure of the steam in venturi-tube 28 are controlled by temperature probe 34 and valve 38 in steam-line 30. The venturi-tube may be replaced by a vapour line 118 (Fig. 3) in which is positioned a fid 100 made up of two portions 102, 104, the upstream portion having in it an annular chamber 106. The materal to be dispersed is pumped through line 116 into chamber 106, and then passes through annular slot 108 from where it is radially injected through annular groove 112 towards the interior wall of pipe 118 so that the material is distributed in the vapour flowing through the annular space defined by the interior wall of the pipe and exterior of the fid. The fid-containing device, or venturi-tube, may be constructed of metal, glass, fiberglass, or polytetrafluoroethylene. Examples relate to thestripping of styrene from styrene-butadiene copolymers, the stripping of polyvinylidene chloride, and the complete removal of liquid from an aqueous-alcoholic slurry of a quaternary ammonium compound. The stripping of the following compositions is referred to:- aroma from coffee, methyl acetate from cellulosic slurry, acetic anhydride from an oily siliconetype material, acrylic acid from acrylic latices, odorous components from fatty oils, fatty acid from glyceride, hexane from fatty oils. When steam may not be used as stripping-agent owing to product reaction or contamination, other vapours, such as toluene, ethylene chloride, or alcohols, can be employed.

Filed: 1970-12-10
Abstract: 1357349 Tape transport SOUTHERN COMMUNICATIONS Ltd 10 Dec 1971 [10 Dec 1970] 58735/70 Heading G5R A tape transport control system allows a person recording on a tape to rewind the tape only as far as his actual starting point on the tape. For this purpose, a digital counter is used to indicate the current position of the tape, e.g. by counting the rotations of the take up spool, and the system provides that the counter is re-set to zero at the end of each period of use of the tape. The system is arranged such that in normal recording periods the maximum value of the highest order digit of the counter is never reached, e.g. if the counter has a capacity of 9999 then the reading 9000 is never obtained. Rewind beyond the zero position is prevented by a make/break arrangement, e.g. a magnetically operated reed switch or a pair of contacts, associated with the said maximum value digit, the arrangement providing that the tape drive circuit is broken immediately the reverse movement tries to change the count from 0000 to 9999.

Title: Apparatus for generating a digital representation of an analogue physical quantity
IPC: G01R19/00
Filed: 1979-04-17
Abstract: A digital representation of an analogue physical quantity, e.g. temperature value, is obtained by measuring a first impedance (RM) the value of which depends on the quantity. The measurement is obtained by applying a voltage to the series combination of this impedance and a second impedance (C) of a different kind and counting, in a counter (PCT), the pulses produced by a source (CL) between the instant the voltage is applied and the instant a threshold detector (DT) detects that the voltage across the second impedance (C) reaches its threshold (Vo). The result is stored in a register (RP1). In order that variations in certain parameters should not affect the result the operation is immediately repeated replacing the first impedance (RM) by a reference impedance (RR), the new result also being stored in a register (RP2). The contents of the two registers are then divide one by the other in a processing unit (PM) to yield a digital representation of the relative values of the first (RM) and reference (RR) impedances. The various operations may alternatively be performed by a programmed digital processing system.   <IMAGE>
