Patent GB-569188-A (GB)
Title: Improvements in or relating to the impregnation of regenerated cellulose staple fibers
IPC: D06M15/423
Filed: 1943-03-04
Abstract: Staple fibres of regenerated cellulose are rendered resilient and more amenable to dyeing, carding, spinning, weaving, &c., and to the production of brushed, napped and pile fabrics, by impregnating them under sustained fluid pressure and at a temperature of 30-100 DEG  F. with a true solution containing from about 5-20 per cent of resin forming components or the primary condensation products thereof, removing the solution from the surface of the fibres, drying and heating to convert the components to an insoluble resin.  Suitable resin-forming components are urea, thiourea, melamine and like carbamides, or phenol, with formaldehyde.  Acid-forming catalysts such as ammonium chloride, ammonium phosphate, chloramides, with addition of free ammonia if desired, and lubricants such as long chain quaternary ammonium salt or sulphonated tallow or oils, may be added to the impregnating solution.  The fibres are impregnated in a pressure dyeing machine, or in an autoclave, and are then subjected to a hydro-extraction treatment, and, if desired, rinsed with water or a concentrated solution of sodium chloride or sodium sulphate. They are then dried at a low temperature and finally heated by infra-red radiation, steam, or hot air to insolubilize the resin. The fibres may be dyed prior to or after the impregnation process, or dyestuffs may be incorporated in the impregnating solution.  In an example, staple viscose fibres are treated under pressure and at a temperature of 55 DEG  F. with a 15 per cent solution of dimethylol urea containing small amounts of cetyl-dimethylbenzyl ammonium chloride and diammonium phosphate. The fibres are then hydroextracted, dried, and heated to insolubilize the resin. Specifications 291,473, 291,474, [both in Class 15 (ii)], 449,243 and 462,599 are referred to.

Title: Improvements in or relating to the recovery of antibiotic materials
IPC: C07H15/238
Filed: 1949-02-10
Abstract: A process for the recovery of antibiotic materials comprises treating a solution of an antibiotic material with activated carbon, eluting the adsorbed antibiotic material from the carbon, and thereafter washing the activated carbon with an aqueous solution of a base having a pH greater than 8.  Specified antibiotics are penicillin and streptomycin.  Specified bases are hydroxides, carbonates, and bicarbonates of the alkali metals, alkaline earth metals, or ammonia, pyridine, trimethylamine and triethylamine.  The regeneration step may be carried out with the carbon in the form of a bed or by agitating a suspension of the carbon in the alkaline aqueous solution.  The carbon is preferably reused in the adsorption step, after if necessary washing it to bring it to the optimum pH. Steam-activated or phosphoric acid-activated carbon may be used.ALSO:Activated carbon, which has been employed in the recovery of antibiotics from their solutions by adsorption and subsequent elution, is regenerated by washing it with an aqueous solution of a base having a pH greater than 8.  Specified bases are hydroxides, carbonates and bicarbonates of the alkaline metals, alkaline earth metals, or ammonia, pyridine, trimethylamine and triethylamine.  The regeneration steps may be carried out with the carbon in the form of a bed or by agitating a suspension of the carbon in the alkaline aqueous solutions.  Steamactivated or phosphoric acid-activated carbon may be so treated.

Title: Improvements in machinery for the automatic production of inlaid linoleum and the like
IPC: D06N7/00
Filed: 1922-02-08
Abstract: 199,062. Ellis, G. W. J., and Westle, J. E. Feb. 8, 1922. Mosaic and inlaid fabrics.- In apparatus for making inlaid linoleum of the type in which pieces are stamped from one sheet of composition into another sheet and the whole pressed on to a sheet of fabric fed in at the end of the machine the operations take place on a table with a number of rising and falling sections; means for waxing the fabric, a special arrangement of feed rolls, stamping heads and grid plates, and details of a finishing hydraulic press are also described. The ground sheet is supplied from a roll, A', Fig. 1, while the material to be stamped in is fed from rolls C<1> mounted on carriers E' suspended from overhead rails F', and rewound after stamping on rolls M<1>. The rolls C<1> are provided with adjustable friction devices D<1> for maintaining the tension, and the rolls M<1> are driven by friction gearing. The ground sheet is fed by rolls R<1> driven by friction gearing and provided with stopdevices consisting of spring-bolts O<3>, Fig. 10, operated by cams U' and engaging with recesses in discs P<3> on the spindles of the rolls R<1>, so that the sheet is moved step by step. The stamping heads H, Fig. 6, are carried by beams F reciprocated vertically by cams and carrying waxing- rolls Q<1> for lubricating the sheets. The cutting dies E<3>, Fig. 8, are carried by boxes K attached to detachable plates I on the stamping-heads, adjustable set-pins J being provided to take the pressure on the plates I. Spring-pressed pistons G<3> and sleeves F<3> hold the sheet down as the cutter rises. Roughened plates J<3> in recesses in the reciprocating sections L of the table are depressed against springs K<3>, and rise as the head rises, lifting the sheet and allowing it to pass easily from the tables. The grid plates L<3>, which are of lighter construction than usual, are separate from the tables L and left behind as the latter fall, thus allowing the waste to be swept off the table by reciprocating brushes &c. The inlaid material is waxed by a web H<2>, Fig. 1, and then passes with the backing-fabric supplied from a roll D<1> to a consolidating-press D<2>. Thence the material passes over a heated race F<2> to the finishing-press G<2>. This is a hydraulic press operated by a reciprocating plunger T<2>, Fig. 2, driven from a crank S<2>, and provided with a pump V<2> driven by an adjustable crank W<2> to supply water for making up leakage. The various mechanisms are driven from the main shafting by loose sleeves and clutches, so that any one can be put out of action and the machine used for different numbers of colours.

Inventor: PEROLLS ROLAND FRANCIS
IPC: H01R13/20
Filed: 1962-01-31
Abstract: 959,500. Two-part couplings. NOVANO Ltd- April 30, 1963 [Jan. 31, 1962], No. 3761/62. Heading H2E. For use in tabulating or recording machines, a plug-and-sooket assembly comprises a pin P and a tubular component T (Fig. 3) which is split longitudinally, and is provided internally with at least two projections, or sets of projections, the first A serving as the primary contact point, and the second B serving principally to work with the pin P as it is inserted, in springing apart opposite sides of the tube, and reducing the amount of initial engagement between A and the pin. The pin has a groove G which receives projection(s) B, allowing projections) A to contact the pin (Fig. 4) again. The two sides of the tube T are urged together by spring means located at the end remote from the pin entry aperture. The projections A, B may be formed, in diametrically opposite pairs, by indenting the metal of the tube. The initial contact between the pin and the projection(s) A (Fig. 2, not shown) serves to wipe clean the contact points of A, but when the pin engages points B, points A are lifted and engagement groove G is then temporarily prevented. The arrangement is used as a link between circuit masks and standard plug boards.

Title: Improvements in Carburetters for Internal Combustion Engines.
Inventor: SAUNDERS ALBERT
IPC: F02M7/22
Filed: 1918-03-04
Abstract: 120,839. Saunders, A. March 4, 1918. Addition to 20733/14, [Class 55 (ii), Gas manufacture &c.]. Spray carburettors.-A carburettor of the kind described in the parent Specification is modified by employing a double-seated valve as B, Fig. 2, with a variable groove H through which the petrol passes from the inlet A to a chamber L from which it issues in the form of a spray past a variable groove N in a screw 0 which is adjustable and held in position by a look-nut 7. In normal working the valve B is raised from its seat G against the action of a spring D by the action of the suction of the engine on a disk C on the stem K of the valve B. The valve is normally pressed on its seat by the action of the spring 0 on a loosely fitting collar E, the tension of the spring being adjustable by a stop-screw F fitted with a lock-nut 5. During the normal working a certain amount of petrol can pass the collar E and spindle K and this is of use mainly during the slow running of the engine. The extent to which the valve opens depends on the position of a cam 2, Fig. 3, against which the disk C is raised by the suction, and this cam 2 is controlled from a sleeve T which controls the air inlets, the cam 2 being automatically set to correspond to this setting by means of adjustable links X, X<1>, which actuate the shaft Z of the cam 2.
