Title: Improvements in or relating to apparatus for coating strip material
Inventor: FARROW VICTOR GEORGE
IPC: B65H39/16
Filed: 1962-10-22
Abstract: 1,000,697. Laminating. EVODE Ltd. Jan. 22, 1964 [Oct. 22, 1962], No. 39931/62. Heading B5N. An adhesive coated strip S having adhesive on both sides and a release paper backing on one side is supplied from a roll R1 and passes round guide rollers 28 and 27 to a guide roller 24 where its exposed tacky face contacts a web material W supplied from a supply roll R mounted on spool 31 via guide rollers 21, 23, and the strip S and web W together pass between guide rollers 25, the release backing strip B at this time being pulled away from the adhesive strip to be taken up into a roll R2 mounted on a spool 19, and the coated web passes between a feed roller 36 and the ledge 26a of a shelf 26 and out of the apparatus through slot 47. The rates of withdrawal of the web with the attached strip from the apparatus, the take-up of the release paper and feeding of the adhesive strip are controlled by a chaindrive system which operates as follows: Depression of treadle 43 causes spindle 17 on which spool 19 is mounted to turn and wind a short length of release paper B into roll R2 causing the strip S and web W to be advanced through the apparatus unwinding a length of strip S from the roll R1. A drive will be thus transmitted through roller 28 and spindle 30 to turn chain wheel 40, also secured to spindle 30, thereby causing the chain 38 to drive chain wheels 37 and 39 and in turn the feed roller 36. Chain wheel 39 may be coupled to an indicating bell or light set to indicate a particular length of strip. A pivoted cutter blade 48 may be associated with the slot 47 to cut the coated webs and is operated by a Bowden cable 49 from a treadle 50 which may be operated in conjunction with treadle 43. The web W may be coated on both sides with adhesive strip, the second adhesive strip S2 being supplied from a roll R3 and passing over guide roller 23 so that its sticky face contacts the underside of web W. The release paper B2 is parted from the strip at rollers 25 and is taken up by roll R4 on spool 20 which has its spindle 18 coupled by a chain drive to turn the same extent as the spindle 17. In this case the shelf 26 is replaced by a conveyer of the track element type, conveniently made of p.v.c. or polythene so as to be readily releasable from the tacky surface. The rollers 28 and 36 preferably have fluted or embossed peripheral surfaces so as to have only limited areas of contact with the tacky surface. The web W may be paper, thermoplastic or thermosetting plastic sheets or films, webs of foam plastic or foam rubber or textile fabric.

Filed: 1960-11-21
Abstract: 2-(31- or 41-carboxyphenylamino)-4,6-di- or -4,5,6-tri-chloropyrimidines are prepared by condensing 3- or 4-aminobenzoic acid with 2,4,6-trichloropyrimidine or 2,4,5,6-tetrachloropyrimidine.  The preparation of the corresponding acid chlorides by reaction with thionyl chloride is also specified.ALSO:The invention comprises vat dyes of formula <FORM:0925998/IV(a)/1> wherein A is the residue of a vattable compound free from sulphonic and carboxylic acid groups, as hereinafter defined, which contains 3 to 8 condensed rings, X is a chlorine atom or a methyl group, Z is a hydrogen or chlorine atom and n is 1 or 2.  A "vattable compound" is a compound which can be converted by reduction into a leuco-form or vat having a better affinity for natural or regenerated cellulose fibres than in the non-reduced and can be reconverted by oxidation into the original chromophoric system.  Suitable vattable compounds are dyes of the anthraquinone series which contain 3-8 condensed carbocyclic or heterocyclic rings or a plurality of anthraquinone units, perylene tetracarboxylic acid series and thioindigoid series.  The dyes are prepared by condensing a suitable vattable compound containing at least one acylatable amino group with a pyrimidine derivative of formula:-  <FORM:0925998/IV(a)/2> (see Group IV(b)).  In an example 5:51-diamino-1:11-dianthrimidecarbazole is condensed with the acid chloride of 2-(31-carboxyphenylamino)-4:6-dichloropyrimidine to give the dye of probable formula:-  <FORM:0925998/IV(a)/3> Further examples are given.

Title: Method of increasing the dispersability of slurry particles
IPC: C09K23/54
Filed: 1958-12-15
Abstract: Metal oxides, and in particular those of thorium, titanium, uranium, zirconium and magnesium, are treated with an organo-silicon compound to coat the surfaces thereof, and the resulting coated particles are thereafter fired at 600-1200 DEG C. to decompose the organosilicon compounds are alkyl and aryl, aralkyl and alkaryl silicon halides, alkyl and aryl halosilanes and alkyl and aryl silicates.  In addition to the organo-silicon compounds, inorganic silicon compounds which decompose on firing to form silica, may also be employed.  According to an example, thorium oxide was exposed to the vapours of a 50% mol mixture of dimethyldichlorosilane and methyltrichloro-silane and then heated to 150 DEG C. to induce polymerization and remove hydrogen chloride. The product was washed with ammonium hydroxide and alcohol and finally with water, to remove the chloride ion and, after drying, the product was fired at 650 DEG C.  Treatment according to the invention facilitates dispersion of the treated particles in slurries and results in extremely low settling rates.

Title: Titration apparatus and method therefor
IPC: G01N27/10
Filed: 1976-09-29
Abstract: 1513608 Titration MEASUREX CORP 29 Sept 1976 [7 Nov 1975] 40399/76 Heading G1N Liquor from a digestor is titrated with carbon dioxide in a sample vessel within the digestor or associated pipework. The end-point is determined from the conductivity of the liquor and the carbon dioxide is added at constant rate and the time to the end-point determined. A reference sample vessel is also supplied in the digestor and means for purging the cells e.g. high-pressure steam is provided. As shown sample cell 26 (with the reference cell behind it and electrodes at its base) is mounted on the inside of digestor wall 38 and in an enclosure provided by covering 46. Wire mesh 48 in opening 47 keeps solids out of the enclosure. Carbon dioxide (and nitrogen for the reference cell) enters through pipes 43 (45) and passes into cell 26 via sintered disc 44. Purging steam is admitted through 51. The measuring circuit comprises an A.C. fed bridge with output connected to end-point detector 34 which responds to a pre-set output voltage. Circuit 30 measures the absolute cell conductivity and is used to determine when the cells are full and empty for sequencing.  In operation, the cells are first purged of liquid by steam jets. After shutting off the steam, the residue condenses and liquor enters through 47 to fill the cell. CO 2  and N 2  are then bubbled into their respective cells, the N 2  serving to keep the CO 2  away from the reference, to equalize bubbling effects on the conductivity and to force excess liquor out of the container and thus isolate the samples. From the CO 2  admission time, the liquor strength is determined.

Title: Improvements in or relating to transistors
IPC: H01L27/06
Filed: 1958-12-17
Abstract: 905,945. Transistors. SOC. SUISSE. POUR L'INDUSTRIE HORLOGERE S.A. Dec. 17, 1958 [Dec. 28, 1957], No. 40796/58 Class 37. [Also in Group XL (c)] In a transistor with two base electrodes disposed at different distances from the emitter the electrodes are so positioned that in response to an increasing base-collector reverse bias the collector space charge region expands to increase the resistance of the current path between one of the base electrodes and the emitter junction without materially altering the resistance of the path from the emitter junction to the other base electrode. In one embodiment, Fig. 2, the base electrodes b 1  and b of a junction transistor are in the form of concentric annuli disposed on opposite sides of an annular groove surrounding the emitter E. In operation, the collector voltage may be increased until the associated space charge region extends as shown by the broken line to the base of the groove to isolate base b from the emitter without appreciably affecting the resistance between the emitter and base b 1 . In an alternative arrangement (Fig. 3) in which the groove is dispensed with, the inner base electrode b 1  and emitter are disposed on a thickened part of the base region. A further alternative shown in Fig. 5 is to mount the emitter and inner base electrode on a region of much lower resistivity than the remainder of the base zone into which the space charge region will only slightly penetrate. In the device shown in Fig. 4, two additional annular zones C 1 , C 2  of the same conductivity type as the collector zone C are provided which are electrically connected to the collector electrode proper. As the collector bias is increased the resistance of the channel between these annular zones is increased until the base electrode b is isolated. The transistors described may be used in bi-stable multivibrator circuits (see Group XL (c)).

Abstract: 1,271,666. Texturing yarns. INDIAN HEAD Inc. 18 Aug., 1969 [10 Sept., 1968; 26 Feb., 1969] No. 41071/69. Heading D1F. A textured, uniformly dyed (or perhaps undyed) filament yarn of synthetic polymer, e.g. polyamide, polyester, polyolefin, cellulose acetate, bicomponent fibres, copolymers and graft polymer, is produced by combining in sequence the steps of knitting a raw (untreated) yarn, heat-setting the knited yarn to form a mild crimp or crinkle therein, subjecting the knitted yarn to "dyeing conditions" (of moisture, pressure, temperature and duration normally employed in dyeing but with or without -the presence of dyestuff or colourant) "deknitting" the yarn, and heat-treating the yarn or plied yarns in the course of texturing, e.g. by stuffer-box or false-twist crimping. The heat-setting is effected at a temperature intermediate the temperature at which the yarn is subjected to dyeing conditions and a higher temperature at which it is heat-treated during texturing and such that the mild crimp is removed. Further heat treatment(s) may be effected provided the temperature thereof is below that of the final texturing step.

Title: Process and apparatus for vacuum-melting and teeming of steels and steel-like alloys
IPC: C21C7/10
Filed: 1964-10-13
Abstract: A process for producing alloys (such as steels) comprises preparing and refining the relatively non volatile components thereof in a copper, ceramic or refractory crucible under a high vacuum of at least 100 millitorr using electronic ray heating, switching off this heating and then using plasma ray heating under substantially normal pressure while adding the relatively volatile components such as Mu, Al, Cu and Pb.  The melt is then teemeed into a mould device (e.g. a continuous casting device), while maintaining the plasma ray heating. The apparatus may have both the crucible and the mould in the same enclosure thus necessitating batchwise production or continuous operation may be gained by using separate enclosures separated by vacuum tight seals.
