IPC: A43D35/00
Filed: 1941-03-22
Abstract: 548,146. Sole-moulding machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). March 22, 1941. No. 3909. [Class 17 (i)] Machines of the kind described in Specification 474,811 are provided with means for positioning the work in predetermined lengthwise and widthwise relation to the moulds but initially out of contact therewith. Upper moulds of wood comprise a heel-end member 20 carried by rods 50, 52 vertically slidable in a carrier 16 adjustable along a cross-head 12, friction against .the vertical movement of the mould being provided by a spring-pressed pad 58. A shank form 18 of wood is secured to the carrier 16. A toe-clamp 22 is mounted similarly to the heel-end mould. The lower mould 24 is of rubber, caused to ascend to operative position and descend to permit work-changing as described in the prior Specification. Just below the normal position of the upper mould a rubber sheet 86, on which the sole to be moulded is positioned, is supported by end clamps carried by levers 96, 104, the sheet being tensioned by a spring 108. A stop 120 on the sheet serves as a gauge for one side of the sole and a step 118 near one end serves as a toe end gauge. To compensate for length of sole the sheet is adjusted longitudinally by a wire cable 138 carried by levers 142, 148 geared together and adjusted by a screw head 196. To move the sheet laterally during adjustment, since width of sole varies with length, inclined slots 134, 136 guide pins secured to the support for the sheet, to which pins the end of the cable is secured. The slots are adjustable transversely of the sheet and angularly, scales 208, 234, being provided for indicating the adjustment which has been made. A scale 252 indicates the normal longitudinal position, which may be varied after releasing clamping nuts 244. A scale 198 indicates the variation which has been made by the knob 196.

Title: Improvements in and relating to the removal of thionates from solution
IPC: C01B17/60
Filed: 1938-02-08
Abstract: 510,804. Recovering sulphur dioxide. LEVY, N., IMPERIAL CHEMICAL INDUSTRIES, Ltd., and BOLIDENS GRUVAKTIEBOLAG. Feb. 8, 1938, No. 3966. [Class 1 (ii)] Thionates are removed from aqueous absorbents used for the recovery of sulphur dioxide from gaseous mixtures by treating the absorbent, before the concentration of thionates therein has exceeded that equivalent to 0.18 grams of oxidizable sulphur per 100 mls. of the absorbent, with sulphur dioxide and copper or a copper compound, boiling the treated solution and filtering it to remove the resultant precipitate. The anion of the copper compound, if such is employed, must be such that it is without injurious effect on the absorbent and the quantity of copper or copper compound must be at least sufficient to depress the thionate concentration to below that equivalent to 0.15 grams of oxidizable sulphur per 100 mls. but insufficient to cause complete decomposition of the thionates. Suitable copper salts are the sulphate or carbonate, and they may be added as such or as an aqueous solution or suspension respectively. It is preferably to maintain the thionate concentration below that equivalent to 0.15 grams of oxidisable sulphur per 100 mls.,say by withdrawing a portion of the absorbent in circulation, treating it and returning it to the absorbent in circulation. If the thionate concentration has been allowed to build up to that equivalent to between 0.15 and 0.18 grams of oxidisable sulphur per 100 mls., the whole of the liquor in circulation must be treated, if desired in batches. This may be effected by treating successive batches of absorbent for thionate removal after which they are stored in a clean vessel until sufficient absorbent has been collected to run the plant. The remainder of the absorbent in circulation is then withdrawn for treatment being replaced by the treated absorbent. The examples describe the application of the treatment to an absorbent consisting of an aqueous solution of basic aluminium sulphate. Specification 445,711 is referred to.

Abstract: 715,117. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 5, 1952 [Feb. 19, 1951], No. 3976/51. Class 38(3) [Also in Group XXXV] In an automatic speed control system for a D.C. hoist motor of the kind in which the armature is supplied from a grid controlled rectifier, and dynamic braking is applied if the load overhauls the motor, the motor armature is provided with slip rings to which the dynamic braking resistor is connected via either a grid controlled rectifier or a saturable reactor. The armature is supplied via the commutator 8 from rectifiers 7, and the field 5 from rectifiers 6. The polarity of the field supply is reversible by contactors 14U, 14D. The dynamic braking resistor R3 is connected to the armature slip rings by rectifiers 9. All three rectifiers are controlled by unspecified apparatus 13, in accordance with the difference between the output voltage of a D.C. tachometer generator 11 and a reference voltage supplied by a network 17 so as to maintain the speed constant. On closing switch 14 the reference voltage gradually builds up according to the time constant of the network and accelerates the motor. On opening switch 15 the reference voltage is gradually reduced to decelerate the motor to inching speed. The reference voltage is of reversible polarity since the polarity of the tachometer generator 11 reverses with the direction of the motor. In a modification, Fig. 2 (not shown), the braking resistor is connected to the slip rings via a saturable reactor controlled by the apparatus 13 above.

Title: Improvements in or relating to pigmenting water-immiscible organic film-forming liquids
IPC: D06P1/44
Filed: 1942-03-26
Abstract: A pigmented water-in-oil emulsion, suitable for use in dyeing and printing textiles and as a coating composition or a printing ink, and in which the aqueous disperse phase comprises at least 20 per cent of the emulsion by weight, is obtained by emulsifying an aqueous solution of a pigment-forming reactant into a water-immiscible organic film-forming liquid and mixing with such emulsion an aqueous solution of a second reactant forming a pigment with the first reactant.  The solution may be added in the form of a water-in-oil emulsion in an organic liquid.  The final emulsion may be inverted to an oil-in-water emulsion before use or the water may be removed to provide a water-free lacquer.  In examples: (1) an aqueous solution of basic lead acetate is emulsified into a solution of an alkyd (castor oil fatty acid-modified glyceryl phthalate) resin in a mixture of a hydrogenated petroleum, toluene and pine oil, an aqueous solution containing sodium bichromate and sulphuric acid is emulsified into a similar solution, the two emulsions are mixed and to the mixture is added a solution of a urea-formaldehyde resin in a mixture of butanol and xylene; the resulting emulsion may be printed on cotton and the print fixed, fast to washing, rubbing and dry-cleaning, by heating at 150 DEG  C.; (2) an aqueous solution containing the o-toluidide of 2 : 3-hydroxynaphthoic acid, turkey red oil and caustic soda is emulsified into a solution containing a urea-formaldehyde resin dissolved in butanol and xylene as in (1), an alkyd resin as in (1) dissolved in toluene, a hydrogenated petroleum and pine oil, and into the resulting emulsion is stirred an aqueous solution of 4 - benzoylamino - 2 : 5 - diethoxybenzenediazomium chloride, neutralised with sodium acetate; the resulting emulsion, after addition of pine oil and water to adjust its viscosity, may be printed on textile materials; (3) the coupling component in (2) is replaced by the anilide of 2 : 3-hydroxynaphthoic acid and the diazo component by 6-benzoylamino-4-methoxy-3-aminotoluene; (4) the coupling component in (2) is replaced by the 1-naphthylamide of 2 : 3-hydroxynaphthoic acid and the diazo component by 4-nitro-2-methoxyaniline; (5) the diazo solution used in (3) is replaced by a solution of Fast scarlet 2G salt; (6) an aqueous solution containing the anilide of 2 : 3-hydroxynaphthoic acid and caustic soda is emulsified into a solution of artificial resins as in (2), an aqueous solution of 6-methoxy-3-nitrobenzenediazonium chloride containing sodium acetate and acetic acid is emulsified into a similar solution, the two emulsions are mixed and diluted with water and passed through a colloid mill, whereupon pine oil and hydrogenated petroleum are added and the whole is stirred into an aqueous solution of sodium lauryl sulphate to produce an oil-in-water emulsion which may be diluted for use as a dyebath for textiles.

Patent GB-572858-A (GB)
Title: A process for the production of synthetic resins
IPC: C08F36/20
Filed: 1942-03-30
Abstract: Synthetic resins are made by polymerizing, in the presence of a catalyst, an unsaturated ester of the formula <FORM:0572858/IV/1> wherein R1 is a hydrocarbon radical containing an unsaturated aliphatic carbon atom, R2 is a divalent hydrocarbon radical and R3 is the same as R1 or is a radical -R4COOR5, wherein R4 is a divalent hydrocarbon radical and R5 is the same as R1. Preferably, R1, R3 and R5 are allyl.  Examples of suitable esters are diallyl diglycollate, dilactate and dihydracrylate, dimethallyl diglycollate, dicrotyl dilactate, dipropargyl diglycollate, methallyl, allyl lactate glycollate, oxy-bis-(crotyl-b -acrylate), oxy-(3-butenyl-g -crotonate, 3-butenyl-a  propionate, methylene bis-(allyl glycollate), dibutin-2-yl diglycollate, oxy - bis - (allyl hexahydro - p - benzoate), oxy - (cyclohexane - 2 - yl acetate, cyclohexene - 2 - yl - b  - propionate), diallyl di - salicylate, oxy - (ethallyl - p - toluate, cinnamyl 4 - cyclohexene - 1 - carboxylate), methallyl allylacetate and isopropenoxypropionate, allyl methalloxyacetate, butenoxyacetate, alloxyacetate, crotyl cyclohexenoxybutyrate, cinnamyl methalloxycaproate, propargyl methalloxybutyrate and cyclopentenyl alloxybenzoate.  Suitable catalysts are hydrogen, benzoyl, barium, sodium, tetralin, olefine, acetyl and acetone peroxides and alkali metal perborates and persulphates.  A soluble fusible polymer is obtained by stopping polymerization before gel formation occurs, for example, by discontinuing the heating or adding a reducing agent to destroy the catalyst, and separating the polymer, for example, by saturation with a solvent for the monomer which is a non-solvent for the polymer.  The soluble polymer may be used for coating surfaces in solution in acetone, methyl ethyl ketone, cyclopentanone, cyclohexanone, ethyl isopropyl and butyl acetates, benzene, toluene, ethylene dichloride, trichlorethylene and chlorbenzene.  Pigments, plasticizers and resins may be added.  It may also be used for moulding, impregnating, forming films and is an adhesive.  Further heating, especially with added catalyst, converts the polymer to the insoluble infusible form. By stopping polymerization at the gel stage, an insoluble mouldable thermosetting polymer is obtained.  The powdered gel incorporating a catalyst is moulded under heat and pressure.  If an oxygen-containing gas, e.g. air, is used as a catalyst, polymerization stops automatically at the gel stage.  Methyallyl allyl lactate glycollate is prepared by heating a mixture of pyridine and allyl glycollate dissolved in dioxane and slowly adding methallyl a -chlorpropionate.  Methylene bis-(allyl glycollate) is prepared by heating a mixture of formaldehyde and allyl glycollate in the presence of calcium chloride.  Benzene is added and water is removed by azeotropic distillation.

Title: Latching mechanism
IPC: B04B7/06
Filed: 1974-01-30
Abstract: 1500141 Latches HOOVER Ltd 27 Jan 1975 [30 Jan 1974] 04336/74 Heading E2A The lid of a spin dryer or like rotary device is secured by a latch which is decoupled from its release handle until the rotation has ceased. The lid 11 carries a keeper 16 by which it is secured by a latch arm 20, 21 pivoting about spindle 22. The latch bolt is itself latched in a retracted position. Fig. 1, by a spring arm 24 until closure of the lid causes the keeper 16 to press it down so that the latch arm 20 can move forward to secure the lid. The latch is released to open the door by sliding a handle 32 (mounted on plate 31) upwards. However, this movement depends on coupling between the handle plate 31 and a plate 41 which is linked to the latch by lever 45. This coupling is provided by a Bowden cable 35, but only when its inner 34 and outer 36 are rendered mutually immovable by a ball 50 blocking movement of the other end of the cable inner. This only occurs, Fig. 1a, when cessation of the rotation of shaft 53 allows the ball to roll back from position 56 to the position in which it blocks the movement of rod 51. Movement of the plate 41 also operates a cut-off switch 60. A modified mechanism is described in Figs. 6 and 7 (not shown).
