Title: Improvements in or relating to methods of applying powders used in agriculture
IPC: A01M9/00
Filed: 1947-12-16
Abstract: Insecticidal, fungicidal or herbicidal powders are electrified by friction before being applied to vegetation by passage in a gaseous current between closely spaced surfaces of a material capable of electrifying the powder by friction, in such a manner that the particles of powder repeatedly strike the surfaces.  An air pump or fan is employed to entrain the powder and force it through the apparatus, The surfaces may be formed by a coil of wire gauze, or by fine threads, blades, balls, or granules and crystals.  Alternatively the powder is forced between parallel flexible sheets held together by springs, the surfaces being preferably irregular, or passed between discs with offset apertures in a sinuous path.  A powder having good charge retaining properties may be employed in addition and the insecticidal powder mixed therewith at the inlet or outlet to the apparatus.  Either or both powers should preferably be pretreated to remove moisture and surface contaminations.  Independent means such as an electrode for precipitating the electrified powder may be provided at the outlet of the apparatus.  Specification 620,675, is referred to.ALSO:Insecticidal, fungicidal or herbicidal powders are electrified by friction before being applied to vegetation by passage in a gaseous current between closely spaced surfaces of a material capable of electrifying the powder by friction, in such a manner that the powder particles repeatedly strike the surfaces.

Title: Improvements in and relating to emulsifying apparatus
IPC: A01J13/00
Filed: 1932-11-23
Abstract: <PICT:0393494/III/1> <PICT:0393494/III/2> Emulsifying apparatus, particularly for making artificial cream, comprises a reservoir 4, Fig. 1, pivotally mounted between a pair of parallel steel bars 2 and having a cylinder 5 projecting downwardly therefrom.  The cylinder 5 contains a piston 6 integral with a pistonrod 9 pivoted at 13 to a pair of interconnected levers 14 carrying a handle 15.  The levers 14 are pivoted to the bars 2 by a U-shaped pin 16 having a short limb securing the levers and detachable therefrom, and a longer limb carrying a nut which prevents complete withdrawal of the pin. The piston 6 is tapered or formed with a flat 7, Fig. 3, at its lower end such that during the pressure stroke liquid is at first returned from the cylinder into the reservoir 4.  The piston-rod 9 carries a member comprising a large and a small baffle 10, 11, which agitate the contents of the reservoir during reciprocation and deflect the returned liquid thus ensuring thorough mixture of the materials employed.  Movement of the piston is limited by a shoulder 8, or by the top edges of the reservoir, and by a spacing member 18 engaged by the levers 14.  The compressed liquids are expelled past a conical valve 19, Figs. 1 and 3, pressed against a seating 19<1> in the cylinder by a pair of springs 20.  The springs 20 are looped round a crosspin 21 in the valve body and are connected to a U-shaped link 22 pivoted at 22<1> to the cylinder 5 and having a cranked portion 22a adapted, when the link is raised after insertion of the valve, to embrace the cylinder. The springs 20 cause the valve to open at a predetermined pressure irrespective of the speed of the piston, and when open the valve provides a crescent-shaped outlet orifice.  The valve body is formed with a concave annular surface 24 causing decompression of, and vortex motion in the issuing liquid, and a flat 23 providing a delivery passage.  In a modified form of valve a tapered portion is formed with concave annular recesses leaving between them circular ribs which engage a tapered seating.  The bars 2 may be extended as at 21 to form the upper member of a clamp for securing the apparatus to a table 27.  Alternatively the apparatus may be detachably supported in a wall bracket having hooks engaging beneath spacing members in the vertical parts of the bars 2.

Title: Improvements in and connected with paper-making
IPC: D21F11/00
Filed: 1936-03-26
Abstract: 472,871. Reinforced paper. KLEIBAUMHUTER, H., and KLEIBAUMHUTER, P., (trading as BAUMHUTER, P., [Firm of]). March 26, 1936, No. 33208. Divided out of 469,342 and addition to 446,049. [Class 96] In a modification of the invention described in the parent Specification for making reinforced paper, fibres from two supply sources are formed into the layers or fleeces which are then combined, with. the fibres of one layer running in a different direction from those of the other, fluid pulp being applied to the common layer in a paper-making machine. The fluid pulp may be applied by cylinders g, l to opposite sides of the fleece which is formed on a conveyer a and transferred to a felt k. The fleece is formed by a guiding and drawing device c which, swinging about an axis e lays a layer d of parallel fibres on to a layer b of parallel fibres on the conveyer a. In an alternative form a small transverse reciprocating conveyer is used above the conveyer a to lav one fleece on the conveyer a, and the longitudinal fleece is laid subsequently, to reduce disturbance due to air currents. A swinging guiding and drawing device is arranged above the small transverse conveyer. In a further modification, a pair of drawing rollers for laying the transverse fleece may be supported on a carriage moving backwards and forwards on rollers over the convever on which the longitudinal hand of fibres is subsequently laid. The combined fleece may be conducted around a roller through a bath filled with fluid paper pulp or may make limited contact with the roller at a point where the latter has emerged from the mass of pulp. More than one zigzag layer may be laid on a longitudinal layer of fibres.

Title: Method of setting hair
IPC: D06M15/11
Filed: 1964-08-14
Abstract: Hair is set by treating it while arranged in a desired configuration with an aqueous solution of a water-soluble alginate, e.g. sodium alginate, having a pH of above 3.6 but below 7, lowering the pH of the applied solutions to below 3.6 to precipitate alginic acid from the solution as a film upon the hair and then drying the hair.  The hair may simultaneously be tinted by adding to the alginate solution a water-soluble dye or pigment dye which dyes the film of alginic acid on the hair.  The pH of the solution on the hair may be lowered by rinsing the hair with a dilute aqueous solution of a physiologically tolerable inorganic or organic acid, e.g. citric or lactic acid.  Alternatively the alginate solution may be adjusted to a pH value between 3.6 and 4 just before applications to the hair with a non-volatile physiologically harmless organic acid, e.g. citric or lactic acid, so that when the hair is dried the pH is lowered by the change in concentration sufficient to precipitate the alginic acid.  The treating solutions may also contain a water-soluble plasticizer for the alginic acid film, e.g. a polyglycol, a synthetic resin, e.g. a polyvinylpyrrolidone-vinylacetate copolymer or dimethyl hydantoin-formaldehyde resin, a preservative, e.g. the methyl and/or propyl esters of p-hydroxybenzoic acid, a perfume and an alcohol, e.g. ethyl or isopropyl alcohol.ALSO:Hair is set by treating it while arranged in a desired configuration with an aqueous solution of a water-soluble alginate, e.g. sodium alginate, having a pH of above 3.6 but below 7, lowering the pH of the applied solution to below 3.6 to precipitate alginic acid from the solution as a film upon the hair and then drying the hair.

Title: Improvements in or relating to sonic gas analysers
Inventor: MARTIN ALBERT EDWIN
IPC: G01N29/024
Filed: 1954-11-17
Abstract: Relates to means for nullifying the effect of standing waves in a sonic gas analyser of the type in which the composition of a sample gas comprising a mixture of two gases is determined by measuring the phase difference between <PICT:0792986/III/1> <PICT:0792986/III/2> <PICT:0792986/III/3> the sound waves received at two receivers from a single transmitter energized at a constant frequency, the phase difference being dependent upon the velocity of sound wave propagation in said sample gas.  As shown in Fig. 3, the analyser comprises a toroidal container with two receivers M1 and M2 spaced equally from a transmitter T.  A datum gas is introduced at U and the sample gas at N.  Outlets are provided at U and V and the relative rates of flow of the sample and datum gases are so controlled that the space between T and M1 contains only the sample gas and the space between T and M2 contains only the datum gas.  In a modification, Fig. 4, suitable for a corrosive or hot sample gas, the transducers T, M1 and M2 are located in containers connecting with the toroid, the main datum gas inlet is at J and a smaller supply of datum gas is introduced at G and H so that the transducers are not in contact with the sample gas.  In both embodiments the electro-acoustic transducers T, M1 and M2 may be piezo-electric or electromagnetic and the phase difference is measured by squaring and differentiating the sinusoidal output from each receiving transducer to produce two pulse trains which control a trigger circuit producing a train of pulses each of duration proportional to the required phase difference, the pulse train being applied to a meter indicating the average value of the current.  The Specification refers to known methods of eliminating standing waves by lining the gas container with sound-absorbing material and the Provisional Specification describes an arrangement, Fig. 4, comprising a transmitter T connected by capillary tubes to two larger tubes P and Q.  A small flow of datum gas, e.g. air, is fed into the tube Q and a larger flow of sample gas into the tube P, a single outlet being provided at the opposite end of the tube P so that the tube Q contains pure datum gas and tube P contains sample gas mixed with a negligible amount of datum gas.

Abstract: 506,756. Moistening yarns during winding. UNIVERSAL WINDING CO. Dec. 3, 1937, No. 33502. Convention date, Dec. 10, 1936. [Class 120 (ii)] - [Also in Group VIII] Yarn is uniformly treated whith a liquid during winding by being brought into contact with a surface whoreon a film of the liquid is maintained, the thickness of the film being controlled by a wiper so as to be varied in accordance with the variation in the speed of the yarn. The yarn y to be wound on the uniformly driven top-tube t, is led through adjustable guide eyes 55, 51, 53, a tension device 20 and tangentially, against a wetting cylinder 43, uniformly driven in a counterclockwise direction by pulleys 46. As the package grows in diameter, the traverse frame 18, 24 pivots about the shaft 22 to move a link 76, adjustably connected therewith, which, in turnmoves a slide frame 72 along a guide bar 70 so to position a wiper blade 60 further from the surface of the wetting-cylinder to provide a thicker film of wetting liquid for the treat. ment of the quicker moving yarn. The operative -blade surface remains parallel to the surface of the cylinder 43 although the guide bar 70 and the shaft axis 44 converge. The blade-carrier slide 72 and bar 70 are carried by a frame 62, 64 freely mounted on the shaft 44, the frame being prevented from rotation by a yoke 67 and an, abutment rod 68. In a modified form of the apparatus, Fig. 10, the wiper blade 106 is adjustably carried by a housing 107, 110 mounted on a shaft 92 eccentrically of the shaft 44. The adjustable link 123, equivalent to 76 of the first embodiment, moves the slide 121 on the guide bar 122, a projecting stud 120 on the slide moving the wiper blade about its pivot shaft 92 by engaging the under surface of an inclined bail or cam member 115. In this form, the blade carrier shaft 92 is prevented from rotating by an adjustable slotted arm connection 95, 96, 100.
