Title: Improvements relating to the binding of packs
Inventor: JONES MAURICE HOLFORD
IPC: B65B13/18
Filed: 1958-08-08
Abstract: 870,736. Bundling machines. POWER STRAPPING SYSTEMS. July 31, 1959 [Aug. 8, 1958], No. 25451/58. Class 94(1). [Also in Group XXX] Apparatus for binding packs with wire &c. comprises a binding machine 10 having a table 11 to which packs are supplied one at a time to be bound, a reciprocating thrust member 16 to feed each pack onto the table, an angularly movable driving lever 20 for actuating the member 16 and initiating the binding, and stop means for halting packs in the binding position. A pack 13 is fed from a shoot 14 across the table 11 until it reaches a stop plate 15a. The driving lever or handle 20 is moved in the direction of the arrow, Fig. 3, and moves the transfer shaft 17 angularly to advance, through links 21, 22, the thrust plate 16 the movement of which is limited by stops 25 on a rod 23 secured to it. The plate 16 advances the pack to the binding position and after being bound it is pushed onto a movable section 34 of the conveyer 32 by another pack taking its place. The section 34, pivoted to a frame 35 at 38, is normally biased towards a horizontal position by an axially adjustable counterweight 39 on a beam 40 and connected thereto by a link 42 and is depressed by the weight of a bound pack to be swung into line with a fixed section 33 of the conveyer 32. The bound pack slides' down the rollers 37. The section 34 may be held in its inclined position during the binding operation by a catch (not shown) which is released on the completion of the operation. During this operation the pack 13 is held stationary by a bar 26 carried by a shaft 27. Two levers 30 on the shaft 27 engage cams 29 on the shaft 17 so that movement of this shaft lifts the bar 26 out of the path of the pack as it is pushed forward by the plate 16. Specifications 523,830 and 777,965 are referred to.

Filed: 1969-05-20
Abstract: 1,207,097. Boots &c. T. FAKUOKA. 20 May, 1969, No. 25595/69. Heading A3B. [Also in Division B5] An article of footwear, e.g. a sandal, consists of a band member 1 and a sole member 2 both of which are integrally and inseparably moulded from synthetic resinous materials and which have a foamy interior 3 and a solid skin 4, the specific gravity of the sole 2 being lower than that of the band 1 by an amount in the range 0.2 to 0.4. The sandal is made by injecting the plastics material, together with a blowing agent, in a hot fluid condition and under sufficient pressure to prevent foaming into the cavity of a cooled mould and then increasing the volume of the mould cavity, e.g. by lowering a bottom plunger, to allow the plastics material to foam in its interior regions where it is uncooled. Suitable plastics materials are polymers and copolymers of styrene, polymers and copolymers a-methyl styrene, ar-methyl styrene or vinyltoluene, mono- and dichlorostyrene, copolymers of vinylidene chloride, polymers and copolymers of methyl methacrylate and ethyl acrylate, polymers and copolymers of vinyl acetate and vinyl butyral, and cellulose derivatives such as cellulose nitrate and cellulose acetate. Suitable blowing agents include dichlorodifluoromethane, carbon dioxide and pentane.

Title: Saponification apparatus and method
Inventor: AKABOSHI MICHIJIRO
IPC: B01F25/74
Filed: 1959-07-27
Abstract: <PICT:0862488/IV (a)/1> In a method of continuously making polyvinyl alcohol from a polyvinyl ester (especially polyvinyl acetate) by base catalysed alcoholysis, a viscous alcoholic solution of the ester is introduced at 6 and flows from the adjustable annular orifice formed by the cap 9 and the lower part of the tube 5, in a cylindrical film 11.  An aqueous or alcoholic solution of a strong base such as sodium hydroxide or sodium methylate is introduced at 4 and sprayed on to the inner surface of the film 11; the reacting film then falls on to the rapidly rotating disc 12 where it is further admixed and projected outwardly in the form of fine droplets towards the walls 14 of the reactor vessel, where it meets a downwardly flowing film of an additional liquid (which may be the recirculated by-product of the reaction) and flows into the slurry 17.  The polyvinyl ester may be a solution of 20% by weight of polyvinyl acetate in methanol, or may be polyvinyl formate; the alcohol may be ethanol, propanol or the like. The base is suitably 23% by weight sodium hydroxide; or may be potassium hydroxide, potassium methylate or sodium methylate.  Both catalyst and polymer are preheated to 35-90 DEG C. and about 0.15 mol. of basic catalyst per mol. of polymerized vinyl acetate can be used. The reactor is preferably heated by hot water circulating in the jacket 2 to 50-90 DEG C.  The polyvinyl alcohol is formed as uniform small particles which may be recovered from the slurry 17 by filtration.
Patent GB-587218-A (GB)
Title: Improvements in or relating to insecticidal compositions
IPC: A01N25/02
Filed: 1944-12-21
Abstract: An insecticidal stock solution comprises a dinitrophenol, an oil soluble lower aliphatic acid which is also water-soluble, e.g., glacial acetic acid, and an oil-soluble emulsifying agent stable in acid media, dissolved in a mineral oil, the proportions being such that when the solution is gently stirred into water an emulsion is formed.  Suitable nitro-phenols are 2 : 4-dinitro-ortho-cresol and 2 : 4-dinitro-ortho-cyclohexyl phenol. Suitable emulsifying agents include oil-soluble petroleum sulphonates formed as by-products in the refining of petroleum oils, amine salts or other oil-soluble salts of sulphated alcohols, cation surface-active substances such as quaternary ammonium or pyridinium salts containing long-chain alkyl groups, e.g., trimethyl octadecyl ammonium bromide or cetyl pyridinium bromide, and non-ionic substances such as polyhydric alcohols partially esterified with fatty acids, e.g., glyceryl dioleate or diethylene glycol mono-oleate, or the alkyl or aryl ethers of polyethylene glycols.  The solution may also contain auxiliary oil-soluble substances which assist emulsification such as phenol, cresols, cresylic acid, cyclohexanol methyl cyclohexanol, n-hexanol and hydroxy-aliphatic compounds.  The mineral oil may be spindle oil.  The solution may be formed by first dissolving the dinitrophenol in the mineral oil with heating, then adding the emulsifying agent and if required, the auxiliary oil-soluble substance with mixing, with or without heat to obtain a clear solution, and finally adding the acid with further mixing.  The Provisional Specification describes also preparations in which the aliphatic acid is omitted and refers to Specification 526,066.

Patent GB-782956-A (GB)
Title: Polyvinyl alcohol yarn
IPC: D01F6/14
Filed: 1955-09-08
Abstract: <PICT:0782956/IV (a)/1> <PICT:0782956/IV (a)/2> Polyvinyl alcohol filaments are obtained by extruding an aqueous solution of polyvinyl alcohol into an aqueous coagulating solution of a salt substantially without oxidizing action, preferably a saturated solution of sodium sulphate, and subsequently treating the filaments so formed while they still contain salt derived from the coagulating liquid with an organic liquid which is a non-solvent both for the salt and for the polyvinyl alcohol.  Such an organic liquid is acetone containing not more than 5 per cent water but other suitable volatile liquids are methanol, ethanol, ethyl acetate, methyl ethyl ketone, and carbon tetrachloride.  To increase the speed of coagulation the spinning solution which suitably contains polyvinyl alcohol in a concentration of 15-27 per cent, also contains a small concentration of the same salt as is used in the coagulating solution, e.g. up to 2 per cent sodium sulphate, when saturated sodium sulphate solution is the coagulant, and the coagulating solution is kept at an elevated temperature, i.e. 32-70 DEG  C.  To prevent any colour-forming tendency, sulphuric acid in an amount of 0.5 per cent by weight of the polyvinyl alcohol may be added to the spinning solution; more preferably, however, hydrogen peroxide as a 3 per cent aqueous solution is added.  Wetting agents may, if desired, also be incorporated in the spinning solution.  Salts other than sodium sulphate which may be used in the coagulating solution are sodium hydrogen phosphate, aluminium sulphate, ammonium sulphate, and potassium sulphate.  As shown (Fig. 1), spinning solution passes through pipe 17 to spinning jet 16 and is spun into coagulant 12. The filaments pass to guide 19 where they converge to form a yarn, and then pass to freely-rotatable rubber covered skew-rolls 22. On leaving the rolls the yarn passes in the manner indicated through the snubbing device 23, the pins of which should have matt surfaces.  By means of the rolls and snubbing pins, stretch of at least 50 per cent is imparted to the yarn.  Above the pins are situated guides 24, 26, 27, 33 and 34, and bobbins 28 and 32 which are used alternately.  The bobbins and snubbing device are enclosed in cabinet 36, within which the humidity is maintained at 100 per cent by means of steam pipe 37 to prevent salt from the coagulating solution crystallizing out on the yarn.  The yarn fully wound up on bobbin 28 is transferred to container 41 (see Fig. 3), in which it is treated with acetone which enters through inlet 42 and leaves through outlet 43.  The acetone extracts both water and salt from the yarn, aided mechanically by the whipping about of the balloon of yarn coming off the end of the bobbin and by the rubbing of the yarn against the snubbing pins 46. The yarn is then dried by dryer 49 and finally wound up on bobbin 54.

Title: Tracking adjustment for u.h.f. circuits
IPC: H01P7/04
Filed: 1953-09-18
Abstract: 756,953. Cavity resonators. STANDARD TELEPHONES & CABLES, Ltd. Sept. 18, 1953 [Jan. 22, 1953], No. 25816/53. Class 40 (8). A tuning device for U.H.F. circuits comprises a coaxial line with a plunger, electrically connected to one of the conductors, movable between the inner and outer conductors to vary the capacitance, and corresponding longitudinal discontinuities in the other conductor and the plunger whereby the capacitance and rate of change of capacitance with insertion is variable on rotation of the plunger relative to the line. In the embodiment shown a shorted quarter-wave line is formed by core 13 in recess 12, and the plunger 6 in contact with wall 12 forms a variable capacitance with an expanded part 15 of core 13, and is movable longitudinally by screw 8. A longitudinal groove formed in expanded part 15 and a corresponding slit 21 in the plunger are arranged so that rotation of the plunger varies the capacitance. The device shown in Fig. 1 comprises four such tunable lines 6, 7, &c. All are simultaneously adjustable by rotation of tuning knob 1 which advances plate 5 and thus the plungers. To track each line at its high-frequency end the insertion of each plunger is independently adjusted by rotation of screws 8, 9, &c., with the dial fixed, while tracking at the other end of the range is effected by loosening bolts 27 to allow rotation of the individual plungers, which after adjustment are clamped to prevent rotation while allowing longitudinal motion by tightening bolts 27 to clamp the members 23 which engage grooves 22 in the plunger. Specifications 730,080 and 756,940, [Group XL (c)], are referred to.

Title: Improvements in welt bar operating means for straight bar knitting machines
IPC: D04B11/32
Filed: 1957-08-16
Abstract: 830,186. Knitting-machines. TEXTILE MACHINE WORKS. Aug. 16, 1957 [Aug. 16, 1950], No. 25970/57. Class 74 (2). The welt bar 47 of a straight bar knitting- machine has at each end a flange 81 which rides on guides 50. After the first course of fabric has been returned to the needles, the tension in take-up straps 56 is released and the fabric is drawn off by the welt-rod 65 and straps 67 with the welt hooks 46 still in the fabric. In order to disengage the hooks 46, levers 116, 105, 100 are actuated to cause lever 88 to turn counter clockwise. A pin 85 on each end of the welt bar 47 engages the surface of lever 88 and the bar 47 is forced to turn about its flanges 81 to a roughly vertical position (Fig. 16), from whence it falls to a horizontal position with the hooks 46 directed away from the needles (Fig. 17) so that the hooks 46 disengage the fabric. To return the welt bar to a position for recommencement of the welting operation, the take-up straps 56 are retensioned; welt-bar 47 turns about pin 85 until it reaches a vertical position (Fig. 16) and then falls back into a horizontal position with the hooks 46 towards the needles. Lever 88 is then returned to a horizontal position, and welt-bar 47 is drawn further away from the needles, so that spring clip 55 on the welt bar comes into contact with pin 52 of pusher arms 51 which subsequently serve to advance the welt bar towards the needles in order that the hooks 46 may take up the first course of the next welt. Specification 594,290 is referred to.
