Filed: 1949-04-14
Abstract: 672,701. Agricultural implements. ALLIS-CHALMERS MANUFACTURING CO. April 14, 1949 [May 26, 1948; June 1, 1948; Aug. 23, 1948], Nos. 10155/49, 10156/49 and 10157/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 13, 1949]. Class 6(i) [Also in Group XXIX] Apparatus for controlling one or more implements associated with a tractor comprises a pivotally mounted draw-bar support member 12 mounted on the tractor for swinging movement longitudinally thereof, a soil working implement 272 connected with the support 12 to exert a draft induced force thereon, a spring 25 acting in opposition to the draft induced force, a hydraulic lift mechanism including a ram unit 34 deriving power from the tractor and connected to the implement to vary the position thereof and a control member 70 connected to the member 12 and to a valve mechanism controlling a hydraulic pump 51 (see Group XXIX) and operating as a result of changes in the draft induced force to effect a lift mechanism regulating movement of the valve mechanism. The member 70 cooperates through a pin and slot connection with levers which allow the position of the lower end of a valve lever to be varied. The valve lever co-operates at its top end with the valve mechanism controlling the hydraulic pump. A hand-lever 212 acts to alter the position of the fulcrum of the valve lever to raise or lower the implement. The levers connected to member 70 may be locked in position to render the member 70 inoperative with respect to the valve lever, the sole control of the hydraulic mechanism then being through the hand-lever 212. The plough is connected to lever 12 by a draught device which allows limited horizontal and vertical movement of the plough. The ram unit 34 is pivoted on the tractor frame and may be swung to operate implements in front of the tractor rear wheels. As shown the ram unit is pivoted to a bell-crank lever 63 which is connected to the plough beam by a link 306. In a modification ridging ploughs are provided at the front and rear of the wheels 2. Two separate ram units are used to raise the front and rear tool units separately or together. The invention may be applied to a towed implement such as a wheeled plough which is connected to the member 12 on the tractor by a draft device including a shock absorbing connection. A ram unit is mounted on the machine frame and connected to the pump and valve mechanism on the tractor by a conduit. The ram unit operates to raise or lower the plough bodies by varying the position of land and furrow wheels with relation to the machine frame.

Abstract: 943,455. Electrophotographic production of printing plates. KALLE A. G. March 16, 1962 [March 23, 1961], No. 10230/62. Headings G2H and G2M. [Also in Division H1] An otherwise known electrophotographic process uses a material comprising a support consisting of metal or having a metal surface, and a photoconductive insulating oxide layer produced by anodisation of the metal. Any metal may be used which is susceptible to anodisation but aluminium, tantalum, and titanium are preferred. The properties of the oxide film may be modified during or after its formation. The material is charged and exposed in known manner and developed in a standard way e.g. with a carrier/toner mixture and the powder image either fixed or transferred to another surface. To make a printing plate from e.g. an aluminium foil with superficial oxide film bearing a fixed resin image the exposed oxide is made hydrophilic by wiping with aqueous phosphoric acid and the plate used directly in an offset printing machine. After use the resin coating may be removed by treatment with ethylene glycol monomethyl ether and the foil can then be used again to make a new printing plate.

Patent GB-666970-A (GB)
Title: Improvements in stabilizing synthetic resins
IPC: C08L27/00
Filed: 1948-04-14
Abstract: Polymers and copolymers of halogen derivatives of ethylene, e.g. vinyl chloride, vinylidene chloride and after-chlorinated polyvinyl chloride are stabilized by addition, before or during hotshaping, of 0.5 to 2 per cent of an alkyd resin made by condensing ethylenic dibasic acids or their anhydrides with alcohols of the formula XHn(CH2.CH2OH)m, wherein n = 0, 1 or 2, m = 3, 2 or 1 and X is sulphur or nitrogen. Up to 50 per cent of the dibasic acid may be replaced by saturated mono- or poly-basic organic acids or anhydrides, e.g. oxalic, malonic, succinic, adipic, tartaric, diglycollic, thiodiglycollic and phthalic acids.  The ethylenic dibasic acids may be maleic, fumaric, aconitic, itaconic, mesaconic and citraconic acids, and suitable alcohols are mono-, di- and tri-ethanolamines or thiodiglycol.  Acids which thermally decompose to form ethylenic dibasic acids, e.g. malic and citric acids and dehydration products of polyalcohols, e.g. morpholine, may also be used.  The acid number of the alkyd resins may be reduced by dissolving the resin in caustic soda solution and precipitating with lead acetate or magnesium chloride.  Optional additions include resins prepared from the alcohols specified and saturated polybasic acids, and alkali metal or magnesium thiosulphates, as described in Specification 664,142.  The stabilizer may be added (1) on a heated rolling mill as such or in a solvent; (2) to the powdered polymer in a mixer; or (3) to an emulsion of the polymer as a p  solution or aqueous emulsion.  Examples describe: (1) condensing equi-molar quantities of maleic anhydride and monoethanolamine to form a viscous resin having a softening point below 40 DEG  C. and an acid number of 145; (2) condensing 3 mols. of maleic anhydride with 2 mols. of triethanolamine at 140-150 DEG  C. under reduced pressura to form e resin having a softening point of 100 DEG  C. and an acid number of 200; (3) condensing equi-molar quantities of maleic anhydride and thiodiglycol at 200 DEG  C. to form a pasty resin having an acid number of 175.

IPC: B01F7/16
Filed: 1957-03-29
Abstract: 853,624. Batch mixing machines; continuous discharge mixing machines. AMERICAN MACHINE & FOUNDRY CO. March 29, 1957, No. 10445/57. Class 86 In a an apparatus for incorporating dry substances into wet substances, for example, as used in the making of cakes, muffins, &c. or plaster, cement, paint and chemical mixtures, the substances within a bowl 10 are circulated therein by means of an impeller 12 fixed to and rotating with a shaft 22. The impeller 12 operates below the level B and at a depth determined by the viscosity of the wet mixture which is revolved circumferentially about the axis of the shaft 22 in the form of two rotating toroidal-shaped volumes R and D having the rotations indicated by the arrows in Fig. 3 and forming a vortex V into which dry substances are fed. The dry substances fed in this manner are thoroughly wetted by being carried between the two volumes R and D, the outer surfaces of which meet at a point P, and the dry substances are thereafter incorporated into the mixture. The depth of the impeller 12 may, in the case of a batch mixer, be maintained by raising the impeller in relation to the feed of dry and wet substances, or, in the case of a continuous-discharge mixer, by adjusting the quantity of the mixed substances discharged through a valve 26 to -that of the total quantity of the dry and wet substances fed thereto. The wet substances 6 are fed at a constant rate from a container 40 through a pipe 42 controlled by a valve 44 and the dry substances F are fed by a metering device 30. The axis of the impeller 12 or, as shown in Fig. 3, the axis of the bowl 10 is preferably inclined to the vertical to improve the intermix of the ingredients within the bowl. The impeller 12 consists of two hollow. frusto-conical members 14, 16 mounted, in spaced base to base relationship, on the shaft 22 by means of spokes 18 and struts 20, the latter being preferably formed as vanes. In modifications the members 14, 16 may be mounted vertex to vertex or may be replaced by flat annular rings, and the members may, instead of being continuous, be in segments. The bowl 10 may be other than hemispherical in shape.

Title: Device for use in connection with operations to be effected on the ends of glass tubes while rotating round their axis, and machine equipped with a number of such devices
IPC: C03B23/09
Filed: 1951-05-04
Abstract: 688,437. Chucks. LUMALAMPAN AKTIEBOLAG. May 4, 1951 [May 4, 1950], No. 10591/51. Class 83 (iii). [Also in Groups XXIII and XXX] Glass tubes 28 are shaped at the ends whilst held in a turret which rotates on a horizontal shaft 13, the tubes being rotated on their own axes. The tubes are held at one end in chucks and are steadied at the other end by a guide comprising two fixed and one displaceable roller. The chucks 29 are spaced around a disc 26 on the shaft 13 and each comprises a sleeve 32 screwed into the disc 26, a ring 36 revoluble on ball-bearings 37 on the sleeve 32, a ring 41 revoluble on the ring 36, and four pairs of links 34, 38 coupling the rings 36, 41. The tube 28 is engaged by the ends of the links 34 which on relative rotation of the rings 36, 41, move towards or away from the axes of the tube. Springs 42, 43 tend to move the rings 36, 41 so that the links 34 are pressed inwardly, the holders being opened for insertion and removal of tubes by a stationary cam 57 engaged by a roller 56 on an arm 54 pivoted at 53 so that the pawls 49, 50, which are pivoted together at 51 and are connected by a spring 59, are swung upwards to engage ratchet teeth 47, 48 on the rings 36, 41. The rings are thus moved relatively in opposition to the springs 42, 43 and the tube-holding links 34 are moved outwardly. The holders are rotated, except at the charging and discharging station, by a belt 61 engaging the rings. In some circumstances, the roller guide at the other end of the tube may exert a screw action on the tubes and tend to displace them axially. To prevent this, the ends of the links 34, 38 under the heads of the pivot-pins 35, 40 are chamfered so that the links may tilt without releasing the tube.
