Title: Acrylic multi-coloured textile products having tone-on-tone effect and process for producing the same
IPC: D06P3/87
Filed: 1970-06-16
Abstract: 1,272,917. Acrylic fibres. JAPAN EXLAN CO. Ltd. 16 June, 1970 [16 June, 1969], No. 29234/70. Heading B5B. [Also in Division D1] Fibrous textile products, e.g. yarn, comprise acrylic fibres P containing acidic groups and acrylic fibres Q containing both acidic and basic groups, the fibres satisfying the inequalities 3#(A-B)#1/ 3 C where C <30 or 5#(A-B)#<SP>1/</SP>4C where C#30 in which A and B are respectively the m.eq./kg. of the acidic and basic groups in fibres Q and C is the m.eq./kg. of the acidic groups in fibres P. The products show tone-ontone dyeing from a single dyebath containing a cationic dyestuff. Other fibres, non-substantive to such dyes, may be present, e.g. wool, polyesters, polyamides, cellulosics and neutral or basic acrylics, and the dyebath may contain a dyestuff substantive to these fibres. The acrylic fibres may contain up to 15% of a neutral monomer. At least 80% of the fibre content may be acrylonitrile, the acidic and/or basic component preferably not exceeding 15%. Fibres P may be made by spinning a polymer of acrylonitrile containing an acid monomer, e.g. Na allylsulphonate or K p-styrene sulphonate, and optionally a neutral monomer, e.g. vinyl acetate or methyl acrylate. The acid groups may alternatively be derived from an acid polymerization initiator. Fibres Q are made by blending P with a basic acrylonitrile polymer containing vinyl acetate and either N,N-dimethylaminoethyl acrylate, 1-vinyl-3-methyl-imidazolium chloride or 2.methyl.5-vinyl-pyridinium methosulphate.

Title: Surface elastic wave electromechanical device
IPC: H03H9/02
Filed: 1975-07-11
Abstract: 1513415 Surface wave devices THOMSON CSF 11 July 1975 [12 July 1974] 29349/75 Heading H3U To prevent bulk wave signals in a surface wave filter or delay line, identical parallel-connected output transducers 3, 10 are positioned equidistantly on opposite sides of an input transducer 5, cancellation of the surface wave signals being prevented by the provision in at least one of the surface wave paths of means which change the propagation characteristics of the surface waves i.e. their amplitude or phase. As shown, conductive bands 19, 20 of unequal width are provided, which introduce a relative phase shift of T 1 between the surface waves 21, 22 so as to provide an output signal at terminals 15, 16. The bands 19, 20 are of aluminium or gold and may be earthed to constitute electrostatic screens. In the embodiment of Fig. 2 (not shown), which is used as a filter in a T.V. intermediate frequency amplifier, the earth electrodes of the transducers have extensions (42-44) which constitute earth connections for bands 19, 20 when they are subsequently deposited. The means which change the propagation characteristics of the surface waves may alternatively be constituted by depressions produced by ion erosion or zones in which the substrate has been implanted with ions. In such cases electrostaticscreening conductive bands (31, Figs. 4, 5, not shown) may be provided.

Title: Electric furnaces
IPC: C03B5/03
Filed: 1973-06-20
Abstract: 1440967 Protective systems OWENS-CORNING FIBERGLAS CORP 20 June 1973 [19 July 1972 19 April 1973] 29355/73 Headings H2H and H2K [Also in Divisions H3-H5] In a through-flow molten glass furnace 10 heat is generated by passage of electric current through the glass between electrodes 17, 18, 19, arranged in a series of rows containing at least three electrodes each and spaced transversely of the flow path, power supplied to a row being reduced or terminated if the temperatures of the glass at two regions adjacent the row and spaced transversely of the flow path differ by more than a particular amount. The temperature of glass leaving such a row will be less and its resistance higher than otherwise and the shortfall of power maybe made up automatically by maintaining constant the power supplied to subsequent rows. Alternatively circuitry may be provided for increasing the power supplied by other rows in dependence on a sensed outlet temperature (Fig. 5 not shown). Temperature differences are obtained from thermocouples or infrared sensors 25, 26 or indirectly from a comparison of the power supplied to pairs of electrodes, (Figs. 3, 4 not shown). Current reducing and terminating circuits include pairs of silicon controlled rectifiers 33-36, controlled normally to pass a part of each cycle or a sequence of cycles with pauses between. Temperature differences or power differences reduce the amount of current passed by the SCR's or inhibit their firing completely. Control circuits 31 are disclosed in Specification 1,161,851. Removal of power from a row may trigger an alarm.

Patent GB-1105130-A (GB)
Title: Production of continuous filament tows
IPC: D02G1/00
Filed: 1965-07-12
Abstract: Flat bands of parallel, continuous, manmade filaments are assembled into a tow in which the filaments are sufficiently intermingled to render the tow resistant to splitting along its length.  Tensioned bands are passed side-by-side and in edge-to-edge contact through sets of feed and draw rolls between which the filaments are oriented by heating and stretching.  All or most of the filaments are diverted from the straight path between the sets by engagement with a guide surface(s) having a V-shaped cross-section, as may be provided by a freely rotatable, double frustoconical reel.  The amount of diversion decreases progressively from one edge of the tow towards the other or from both edges towards the centre so that the filaments are consolidated into a tow, or perhaps two separate tows formed one on each sloping face of the V surface.  The thickness of the final tow varies across the width thereof.  The one tow (or the two tows merged into a single tow which is readily splittable along one line only) is crimped in a stuffer-box and subsequently split and/or processed e.g. stapled, opened and spun into yarn or directly converted to spinnable sliver.  The crimps in the filaments may be "deregistered" by passage of the tow between rollers the surface of one or both of which is formed with helical grooves and ridges and the resultant tow is opened and spread laterally by passage through a series of air spreaders to form a diaphanous but coherent web.

Title: Improvements in filling feeler mechanism for looms
IPC: D03D51/34
Filed: 1919-11-26
Abstract: 154,446. British Northrop Loom Co., (Northrop Loom Co.). Nov. 26, 1919. Weft-feeler arrangements.-A weft-feeler for use with either bobbins or cops comprises a side-slipping feeler A, which is provided with a toothed weft-feeling tip B so as to act in the normal manner when bobbins are in use, by slipping laterally along the bared bobbin when the weft is nearly exhausted, but is also provided with a feeling-finger G adjustably screwed to a vertically-extending standard H on the feeler A, so that this can act as a measuring feeler when cops are in use. the finger in such cases contacting with and sliding along a smooth fixed datum surface such as the shuttle or shuttle box, when a predetermined state of weft exhaustion is reached, thereby causing the feeler to make the operative side-slipping movement that actuates a slotted controller X governing weft replenishment. When the weft is not nearly ex. hausted, the tip B engages therein, and the feeler is moved frontwards thereby without moving laterally sufficiently to actuate the controller X.

Title: Compressible metallic bellows
IPC: F02P7/00
Filed: 1972-06-23
Abstract: 1377087 Welding by fusion; soldering; making bellows A MCNAMEE and J FERGUSON 21 Nov 1972 [30 Nov 1971 23 June 1972] 55443/71 and 29461/72 Headings B3A and B3R [Also in Division F1] A bellows for use in a compressor, engine or actuator is produced from a plurality of sheet metal, e.g. stainless steel annuli 1, each annulus 1 being produced from a flat annulus in which the inner and outer margins 4, 5 of the annulus are relatively displaced while being kept parallel so as to form a portion between the margins having positive AC and negative CA curvature. The curved portion may correspond to the natural curve ACB produced by the displacement of the margin or that curve modified by increasing (to the dotted position A<SP>1</SP>C<SP>1</SP>), or decreasing, Fig. 8 (not shown), the curvature of the outer positive curvature portion AC. To produce the natural curve ACB, each annulus is clamped by its outer margin between two halves of a rigid ring 7 while axially displacing a rigid cylindrical member 8 clamping the inner margin. With the member 8 in its displaced position the annulus is stress-relieved by heating. The annuli are arranged axially in oppositely facing pairs and brazed, soldered or welded together along their adjacent inner and outer margins, with or without the interposition of inner or outer spacer rings (27), Fig. 13 (not shown). Electron beam welding is preferred, the beam being directed so as to impinge radially upon the abutting edges of the respective margins whilst rotating the annuli relative to the beam. The bellows may be circular or oval in cross-section and each annulus may be of two or more sheets.

Title: Precipitating process
Inventor: ROLAND KLAUS
IPC: B01J19/00
Filed: 1969-06-11
Abstract: 1,214,128. Precipitation. INDUSTRIEFORSCHUNGSZENTRUM CHEMIEANLA - GEN. 11 June, 1969, No. 29642/69. Heading B1X. In a precipitation process an aqueous salt solution is conducted in a first column 1 in counter-current with a mixture of precipitating agent, e.g. methanol, and a carrier substance, e.g. octanol. Precipitation occurs and the charge solution, enriched in precipitation agent, and the precipitate are conducted to a separating apparatus 3 where the precipitate is separated out. The mixture of residual charge solution and methanol passes to the head of a second column 2 and is conducted in counter-current with the octanol containing some mathanol, which has been conducted to the sump of the column 2 from the head of the column-1. The octanol dissolves out most of the methanol in the residual charge solution and is used to precipitate out further charge solution in the column 1. The residual charge solution largely free of methanol is conducted away at the sump of the second column 2. The octanol emerging from the head of the column 1 has its methanol content reduced by, e.g. distillation, to facilitate subsequent methanol take-up, as may be the residual charge solution leaving the column 2, any methanol remaining being distilled in a third column 4. This separated methanol can be added to the change solutionmethanol mixture at 5 or to the octanol supplied to the column 1.
Patent GB-932434-A (GB)
Title: Improvements relating to organopolysiloxanes
IPC: C07F7/20
Filed: 1960-08-30
Abstract: A lower alkyl chlorophenyl siloxane liquid is stabilized by adding thereto an iron salt of an organic acid, bubbling an oxygen-containing gas therethrough while the mixture is heated, and filtering off the precipitate formed during the bubbling operation. The resulting filtrate serves as a concentrate which can be added to additional amounts of alkyl chlorophenyl siloxane liquids, from 0,15to 10 parts by weight of the concentrate effectively stabilizing 100 pts. of the siloxane liquid.  The siloxanes used contain lower alkyl radicals and phenyl radicals having 3, 4 or 5 chlorine substituents, the chlorinated phenyl radicals constituting from 1 to 7% of the total number of Si-bonded radicals.  Iron Iron salts specified are iron acetate, propionate, butyrate, isobutyrate, n-hexoate, 2-ethylhexoate, benzoate, naphthanoate, toluate, cycohexanecarboxylate, oxalate, succinate, adipate, maleate, phthalate and rosinate.  The iron salt per se or in solution or paste in an inert solvent, is usually used in amount of 0,1 to 2,5 pts. (by wt.) of iron per 100 pts. of siloxane.  In a typical example (1) air was bubbled through a mixture of a liquid siloxane containing per Si atom an average of 2,22 methyl radicals and 0,03 chlorophenyl radicals containing an average of 4 chlorine atoms per phenyl radical, and a paste of iron octoate in mineral spirits, while the temperature was raised to 280 DEG C. for 90 minutes and then cooled; the precipitate which formed was then filtered off to yield a filtrate which constituted the desired concentrate.  Uses: As heat transfer and hydraulic liquids and as lubricants.  Specifications 586,187, 586,956 and 650,800 are referred to.
Patent GB-1037087-A (GB)
Title: Separating and washing plant
IPC: C08B3/22
Filed: 1964-07-28
Abstract: In a countercurrent washing plant comprising an upward-moving inclined surface on which rest a plurality of spaced rollers, a mixture of comminuted solid and liquid is fed in at the bottom end of the surface and solid collected at the top, while liquid is fed in at the top end of the surface and collected at the bottom.  In Fig. 1 (not shown), the inclined conveyer surface driven by roller 11 moves on the bottom of rectangular trough 1.  The roller 3-7 rest on and are free to move to and from the surface of the belt 2.  The solid-liquid mixture from feed 18 reaches the belt between rollers 3 and 4 and travels under the rollers up the belt.  Liquid from feed 19 reaches the belt between rollers 6 and 7 and travels downwards, being dammed behind each roller in turn.  Sliding of the conveyer over the surface is facilitated by coating the surface with polytetrafluoroethylene or by feeding a liquid such as water from pipe 15 (Figs. 1 and 2, not shown) to the underside of the belt. Instead of rotating freely, the rollers 3-7 may be power driven.  The apparatus may be used in the purification of cellulose acetates prepared from cellulose and acetic anhydride.  The bulk of the solids are first separated from the acetic acid solution by known means such as the passage of the slurry over a perforated travelling band such that the liquid drains back into the vessel containing the slurry, while the solids and remaining acetic acid are passed to the apparatus of the invention.ALSO:In a countercurrent washing plant comprising an upward-moving inclined surface on which rests a plurality of spaced rollers, a mixture of comminuted solid and liquid is fed in at the bottom end of the surface and solid collected at the top end while liquid is fed in at the top end of the surface and collected at the bottom end.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/18
Filed: 1963-07-29
Abstract: <PICT:1011935/C1/1> In a process for the production of a ribbon of glass by flowing molten glass on to a liquid support (e.g. molten tin, silver, lead or their alloys), a liquid, particularly one based on boric anhydride, which wets glass, has a surface tension different to that of the glass, and does not react with or mix with the liquid support, is brought into contact with the edge of the glass ribbon, thus forming a band, the surface tension characteristics of which are different from those of the glass itself.  Other oxides, such as those of potassium, lead or vanadium may be used in combination with the boric anhydride.  A ribbon of glass 6 is formed on a molten bath of denser liquid 4, e.g. molten tin, and at the point 7 where the glass begins to spread out there is introduced into contact with each of its edges liquid boric anhydride through tubes 8.  The boric anhydride also covers a small portion of the tin bath in the immediate neighbourhood of the glass ribbon to prevent oxidation. Alternatively, the liquid anhydride may form a film covering all the free surface of the liquid support not covered by the glass.

A vehicle control pedal assembly, especially for a hydrostatic transmission, comprises a pair of pedals 2 pivotally mounted in a support 1 above a rocker arm 13 operatively connected to the transmission and having lobes 15a and 15b so that depression of one pedal or the other causes that pedal to contact the associated lobe and to rotate the rocker arm whereby the corresponding transmission control is effected and the other lobe is moved to a position where it cannot be contacted by the other pedal. Locking means 7 are associated with each pedal and may be held in operative and inoperative positions by spring-urged detents. The rocker arm 13 is spring-biased to a neutral position by an arm 16 engaged by spring devices 19. The arm 16 may be part of the rocker arm 13 or may be separately attached to the shaft 14 upon which the rocker 13 is mounted and the transmission control member may be connected at 13 to the rocker arm 16 or may be connected to the rocker by means of a cable wound round a shaft rotated by movement of the rocker. The transmission control may be such that depression of one pedal causes the vehicle to move forwardly and of the other causes movement in a rearward direction.

Title: Rate of change of fluid pressure indicator applicable as a rate of climb indicator or as an accelerometer for aircraft
IPC: G01P3/62
Filed: 1947-11-12
Abstract: 653,399. Electric indicating systems. SQUARE D CO. Nov. 12, 1947, No. 30055. Convention date, Nov. 27, 1946. [Class 40 (i)] [Also in Group XIX] In an instrument for indicating rate of change of fluid pressure, e.g. a rate of climb indicator or accelerometer for aircraft, an electric motor is rotated at an average speed determined by the rate of change which is indicated by a tachometer or equivalent device driven by the motor. As shown, a two phase motor 9 is controlled in the manner described in Specification 620,279, so that an electric contact 36 driven thereby always follows up a contact 32 actuated by aneroids 16 (see Group XIX). Thus the average speed of rotation of the motor shaft corresponds to the rate of change of pressure detected by the aneroids, and this speed is indicated by an eddy-current tachometer including a drag cup 54 and a magnet 55. U.S.A. Specifications 2,232,789 and 2,437,064 are referred to.
