Patent GB-286006-A (GB)
Title: A new or improved means for coating or ornamenting surfaces of wood, glass, or other material
IPC: B29C65/48
Filed: 1926-11-29
Abstract: 286,006. Smith, M. Nov. 29, 1926. Ornamenting.-A surface decoration or finish is produced, e.g. on tennis-racket-handles or electric lamps, by placing on the surface a yarn or fabric, preferably consisting of a cellulose ester such as cellulose acetate, and applying, either with the fabric or subsequently, a solvent, such as ethylacetate, which partly or wholly dissolves the fabric and causes it to adhere to the surface. The surface may initially be varnished to assist in the adhesion, and differently coloured fabrics or yarns may be used to provide special decorative effects. A yarn may be wound spirally on to a rotating article and a solvent applied to the yarn whilst it is being fed or subsequently. Also, the fabric may be tubular in form or otherwise shaped to conform with the article to be decorated.

Title: Improvements in or relating to electroluminescent cells
IPC: H05B33/20
Filed: 1955-10-21
Abstract: 788,479. Electroluminescence. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Oct. 21, 1955 [Nov. 1, 1954], No. 30130/55. Class 39(1). Electroluminescent particles embedded in dielectric material are oriented in groups perpendicular to the parallel electrodes of the cell by applying an aligning electric field whilst the dielectric is in a fluid condition. Heat is applied simultaneously with the orienting field to render fluid the thermoplastic and thermosetting dielectrics. Polyester epoxy, acrylic and styrene resins are satisfactory thermosetting dielectrics. Canada balsam, polymerized ethyl methacrylate or polyvinyl acetate are suitable thermoplastic materials. The alignment apparatus for a cell comprising a backing plate 22, electrode 20, high dielectric constant layer 18, e.g., mica, phosphor-dielectric layer 16 and subsequently a further electrode layer with bus-bar terminals, consists of spacers 27 placed on the layer 18 to confine the phosphor dielectric suspension. A heater 26 is placed on top of the assembly and a field applied between the heater and the electrode 20. The phosphor dielectric may be introduced when the heater is already in position by means of the overflow ports 28. The alignment of the phosphor particles in the fluid dielectric is thought to be primarily a dielectric phenomenon. Dielectric materials which polymerize at room temperature, e.g. water emulsified acrylic resins or epoxy resins, may also be used thereby dispensing with the heating step.

Title: Improvements in and relating to the manufacture of insecticides
IPC: A01N59/10
Filed: 1927-11-10
Abstract: 301,186. Groombridge, W. H., and Dickinson, Ltd., A. J. Nov. 10, 1927. Insecticides.-In the manufacture of aqueous solutions, suspensions, or colloidal solutions, suitable for use as insecticides, particularly on cotton plantations to destroy boll-worm and leaf-worm, ammonium silicofluoride in an aqueous medium is treated with one or more soluble soaps. Ammonia or a caustic alkali may be added at any stage of the process. The mixing operations are preferably carried out below 30‹ C. The relative proportions of soap and silicofluoride may vary within fairly wide limits. In one example 60 lbs. of soft potash soap having a fatty acid content of 40 per cent are made up to 20 gallons with water. In a separate vessel 20 lbs. of ammonium silicofluoride are dissolved in 15 gallons of water and are treated with a solution of 10 lbs. of caustic soda in 5 gallons of water. The second solution is gradually added, whilst stirring, to the first solution. According to another example 14 lbs. of ammonium silicofluoride are dissolved in 13 gallons of water and 5 lbs. of caustc soda are added. This mixture is then added to a solution of 2¢. cwts. of soft potash soap having a fatty acid content of 12.6 per cent, the mixture being made up with water to 40 gallons. These insecticide solutions may also be mixed at any convenient stage with other suitable substances.

Title: Improvements in rubber treatment and article
IPC: B29C37/00
Filed: 1949-11-25
Abstract: <PICT:0660070/IV (a)/1> The surface layer of a vulcanized synthetic rubber article, e.g. butadiene-styrene or butadiene-acrylonitrile copolymers, containing a combined zinc activator of vulcanization in a proportion of less than 25 parts of the activator per 100 parts of rubber is modified to resist over-vulcanization by treatment with an alphamono-halogenated, or an alpha, alpha1-dihalogenated lower aliphatic saturated monocarboxylic acid in which the halogen is chlorine or bromine, e.g. monochloroacetic, alpha-chloropropionic, alpha-bromopropionic, alpha-bromobutyric, alpha - bromocaproic, alpha, alpha1 - dichloroacetic, alpha, alpha1 - dichloropropionic, or alpha, alpha1-dibromocaproic acid, and they may be applied directly or dissolved in water.  The process is preferably applied to the treatment of conveyer belting used in the manufacture of rubberized fabric.  In an example, a cloth liner 26, Fig. 2, such as a loosely woven cotton cloth is passed from roll 27 under rollers 28 which are immersed in a solution of 100 parts of monochloracetic acid in 150 parts of water and then fed up to meet the vulcanized rubber belt 30 coming from roll 31, the liner and belt are then wound together on to roll 32.  After being allowed to stand for 48 hours the acid is found to have penetrated to a depth of about 0.020 inch.

Title: Milk flow sensing valve for treat cup release
IPC: A01J5/01
Filed: 1972-06-28
Abstract: 1398616 Milk flow sensing valve W F ABRAHAMSON J H ABRAHAMSON and B H ABRAHAMSON 28 June 1972 [30 June 1971 3 March 1972] 30296/72 Heading AIM [Also in Divisions F2 and G3] A sensing valve in a pneumatic milking system cuts off the vacuum to the teat cups when the milk flow stops; it may also be arranged to actuate apparatus for withdrawing the teat cups. In one embodiment (Fig 1) the sensing valve comprises a chamber 4 with a milk inlet 15 and a milk outlet and vacuum pipe 6. An annular float 5 carries a valve member 8 in the form of an inverted cone or flat disc which closes the pipe 6 when the chamber 4 is empty. To permit residual milk to drain from chamber 4 after the closing of the main valve 8 the floor of the chamber 4 slopes towards a drain outlet 11 connected to pipe 6 closable by a needle valve 13 after the valve 8 has closed, a lost-motion connection being provided between the valve member 8 and the float 5. Alternatively there may be a drain aperture in the pipe 6 at the base of the chamber 4 which is closed by the descent of the float 5. The valve may be opened initially by lifting the float 5, either by a spring biassed plunger, or by distorting the flexible bottom of chamber 4 by a cam-like lever or trigger; this may be accomplished using an electric solenoid. Alternatively a by-pass conduit 16, with a tap 17, may be provided. Alternatively the sensing valve may simply be inverted. A screen 26 (Fig 4) adjacent the drain outlet 11 and a transparent section of the wall 1 of the chamber 4 collects evidence of mastitis. In another embodiment (Figure 3, not shown) the float is sperical, is disposed above the vacuum pipe 6, and acts itself as the valve member. Above the float is an arcuate deflector plate under which the float is located when the valve chamber is full of milk. The milk inlets are so located at the top of the valve chamber that the milk flows over the deflector plate and in a spiral path, so as to reduce turbulence. The drain outlets for the valve chamber also act as air vents. The milk outlet has a wide section to provide for milk return on surging. In a further embodiment (Figure 4) the valve member is formed by a lip 21 on the float 5, the resulting upper and lower ports 4a, 4b of the chamber 4 being joined by a by-pass conduit 24 with a tap 25 for initial activation of the valve. A diaphragm 27 is connected to a flexible rubber or plastics tube 32 which joins two tubes 30 and 31 to allow air supply to a pneumatic cylinder which when activated removes the tea cup assembly and supports it clear of the ground. Activation of the ram is prevented while vacuum exists in the chamber 4a by the occlusion of the angled end 30a of the tube 30 by the downward position of the flexible tube 32, and because in that position a transverse slit 33 in the wall of the flexible tube 32 is open, thus venting the pneumatic cylinder.

Abstract: 1,014,483. Packaging-machines; shoots. SACK FILLERS Ltd. June 6, 1962 [Aug. 23, 1961], No. 30385/61. Headings B8C and B8S. Paper bags 5 are filled from a hopper 1, which receives a weighed charge of flowable material 2 from an automatic scale, and the material 2 passes down a shoot 4 having means, e.g. an adjustable plate 8, for restricting the crosssectional area of the flow, thereby allowing air to pass from the bag to an outlet 15 in the shoot. The cross-sectional area of the material 2 is further restricted in the lower part of the shoot owing to the taper of the shoot wall. The bag may be seated on a settling device 6. An adjustable valve 7 controls outflow from the hopper. In a modification the bags may be filled and weighed simultaneously, in which case the valve 7 is replaced by a manually or automatically operated feed control gate and the shoot is mounted on the scale supporting the bag.

Title: Improvements in or relating to the fractionation of hydrocarbon mixtures by means ofsolid adsorbents
IPC: C07C7/12
Filed: 1949-11-28
Abstract: <PICT:0661741/III/1> The concentration of an intermediate component B of a vaporous mixture of A, B and C wherein A is less readily adsorbed and C more readily adsorbed than B, is effected by passing a fluidised solid adsorbent, preferably charcoal, downwardly through a primary tower 1, which has an adsorption section 2 above the tower feed point 5, a middle rectification section 3 and a heated lower desorption section 4 below the feed point, removing the unadsorbed component A from the top of the tower at 10 and 14, a portion being recycled by blower 34 through lines 13 and 6 to the top of the adsorption section, removing the desorbed component C from the desorption section 3 at 23, and passing a vaporous stream of components B and C substantially free from A from the rectification section 3 via pipe 17 to an auxiliary tower 15, to pass in countercurrent to a stream of adsorbent entering the top of the auxiliary tower by line 16 from the adsorption section 2 containing components A and B substantially free from C, and withdrawing component B, freed from A and C from the centre of the auxiliary tower at 18.  The unadsorbed components are returned to the adsorption section of the primary tower through line 19 whilst the adsorbent, now containing component C is returned via line 20 to the rectification section of the primary tower.  A portion of the adsorbent may be continuously withdrawn from the adsorption section 1 of the primary tower via line 30, to a regenerator 31, to flow countercurrent to hot flue gas and steam entering at 32, the regenerated adsorbent being recycled to the base of the desorption section at 37.  Steam is passed into the desorption section at 22 and a slurry of the adsorbent resulting from the working of the effluent gases is injected at 35.  The process is applicable to the concentration of a C2 hydrocarbon from its mixture with C1 and C3 hydrocarbons, particularly mixtures of methane, ethane, ethylene, propane and propylene with or without inert gases such as nitrogen. Specification 638,745 is referred to.

Abstract: 323,019. Moulton, H. F., and Tschudin, E. June 16, 1928. Divided on 322,998. Cellulose nitrates and xanthates.-Wood pulp is stirred up with 70 per cent of water, treated with about 10-15 per cent of caustic soda and then with 5-10 per cent of carbon bisulphide to form a gelatinous paste, which can be pressed through dies into continuous strings and subsequently cut into pellets or alternatively extruded directly in the form of short pellets. The strings or pellets are immersed in a hardensolution, for example an acid or acid salt solution, washed and dried, but if desired they may be immersed in a glycerine bath before drying. The pellets in an air dried state are then nitrated preferably in a centrifugal nitrator. A nitration mixture may be used in which the proportions differ substantially from those ordinarily used, for example, a mixture comprising 81 per cent of nitric acid, 16 per cent of sulphuric acid and 3 per cent of water. Alternatively, the material may be nitrated in the form of strings, which can be subsequently divided into pellets. The material is freed from the nitration mixture, preferably bv means of a centrifuge, washed with water, and stabilized by boiling. The Provisional Specification refers to the employmeent of soda lye of 30-36 BÚ. in quantity amounting to 80 per cent on the weight of cellulose and 20 per cent by weight of carbon di-sulphide for gelatinizing the wood pulp.
