Inventor: WARSON HENRY
IPC: C08F2/22
Filed: 1963-11-19
Abstract: Acrylic polymer emulsions which are controllably thickenable on addition of alkali may be prepared by polymerizing in emulsion at least one acrylic monomer, 8 to 15 weight per cent of the monomers of a copolymerizable acid and a percentage of a cross linking monomer such that the fraction obtained when its percentage by weight multiplied by the number of polymerizable units in the molecule is divided by its molecular weight does not exceed 0.04. Specified acrylic monomers are acrylic and methacrylic esters, acids and derivatives thereof. Specified acids are acrylic and methacrylic acids.  Specified cross linking agents are multiunsaturated vinyl and allyl compounds, e.g. acrylic and methacrylic diesters of ethylene glycol and triethylene glycol.  Polymerization may be effected in the presence of emulsifiers, e.g. tetrasodium dicarboxyethyl octadecyl sulphosuccinamate, alkyl phenyl polyethers, fatty acid polyether esters and sodium alkylaryl sulphonates; modifiers, e.g. t-dodecyl mercaptan; and catalysts, e.g. potassium persulphate or redox systems comprising ammonium persulphate, sodium formaldehyde sulphoxylate and ferric chloride.  The emulsions may be thickened with alkali, e.g. ammonia, and used in coating compositions. Examples describe the emulsion polymerization of methacrylic acid, ethylene glycol dimethacrylate and (I) ethyl acrylate, (II) ethyl acrylate and butyl acrylate and (III) ethyl acrylate and 2-ethylhexyl acrylate.

Abstract: 1,163,466. Baling apparatus. WELGER GEB. 6 Oct., 1967 [27 Oct., 1966], No. 45760/67. Heading B5F. [Also in Division A2] Baling apparatus comprises four rollers 7, 7a for winding and compressing material such as fodder fed thereto by a conveyer 4, and further rollers 17 for consolidating and smoothing the resulting strand (30) of material, at least one of the compressing rollers 7, 7a being resiliently movable away from the strand, this movement causing similar movement of one of the rollers 17. As shown, two of the rollers 7, 7a are mounted at one end in self-aligning bearings 9 and at the other end in bearings (10) carried by frames 11. These frames are pivoted at 29 and biased towards each other by a spring 12. The rollers 17 are supported at one end by bearings 18 and at the other end by drive shafts. The upper pair of rollers 17 are mounted on frames 20, 21 pivoted at 29 and biased together by springs (22). A pin 28 carried by the mounting frame of roller 7a engages a plate 20a connected to one of the pivoted frames 20 so that movement of roller 7a away from the material to be baled causes the roller 17 to move similarly. Roller 7a can return, however, without affecting the position of the roller 17. Roller 7a has retractable tines 8. The rollers 7, 7a are shown as conical but may be cylindrical or with sides bulging inwardly or outwardly. The axes of the rollers may be parallel or oblique to the axis of the device.

Filed: 1972-10-06
Abstract: 1373866 Vacuum variable capacitors ENGLISH ELECTRIC VALVE CO Ltd 4 Oct 1973 [6 Oct 1972] 46179/72 Heading H1M The vacuum envelope of a vacuum variable capacitor comprises glass sleeve 1, metal members 2, metal end plates 21, 23 and, to allow axial motion of mobile electrodes 3, bellows 22, a further bellows 6 connected between end plate 21 and mobile electrode carrier member 5 and located within the vacuum envelope being of relatively large diameter so as to provide a low impedance path for current flowing through the capacitor. Vacuum-retaining bellows 22 which carries only a small proportion of the current can accordingly be of small diameter and therefore less vulnerable to the pressure difference on either side thereof. The actuation mechanism accordingly requires only a low torque and is suitable for motor control.

Abstract: 1,197,439. Sewing machines. NEWEY BROS. Ltd. 13 Oct., 1967 [19 Oct., 1966], No. 46648/66. Heading D1G. A needle-feed sewing machine is modified to sew eyes or the like on garments by providing needle-diverting means comprising sensing means engagable with the work and a catch coupled to the sensing means in such a manner that the movement of the sensing means on engaging an eye causes the catch to restrain forward rocking movement of needle barsupporting frame, and by substituting for a conventional pivotal connecting link in the means for rocking said frame a link in which the distance between the pivot centres is altered against spring bias when said catch operates to prevent the forward movement of the rocking frame. A clamp 30, secured to a presser bar 31, is rigid with a depending bracket (33) on which is pivoted a bell crank lever having a lower arm 35 carrying a work-engaging hooked feeler and an upper arm 36 pivotally carrying a block (37) slidable in a slot 38 in an arm 39 pivoted to bracket (33). A spring 47 biases arm 39 downwardly against a stop 44 rigid with bracket (33). A compression spring 43 is interposed between clamp 30 and a clamp 42 secured to a rook frame 13 slidably supporting a needle bar 12 carrying a needle 11. The linkage oscillating frame 13 contains a pivotal link 18 having a cylindrical pivot-receiving hole 21 and an elongated hole 22 slidably supporting a member 23 biased by a sprng 24 to bold a pivot at the inner end of hole 22. The arrangements is such that when the feeler rises on a wire fastener during the forward movement of frame 13, arm 39 is raised to position a stud 40 thereon in the path of movement of an abutment (41) on clamp 42, whereby movement of frame 13 is arrested, member 23 yielding to permit lost motion for this purpose, and the needle on descending avoids the fastener. On the return movement of frame 13, an arm 45, rigid with clamp 42, engages a stud 46 on arm 36 to raise the feeler from the work. In a modification clamp 42 is replaced by a bracket having a pin entering a hole in the needle bar rocker frame.
