Abstract: A process for the production of stable aqueous emulsions of polymers, which can be cross-linked by oxidation and which contain units of esters of a , b -olefinically unsaturated carboxylic acids and alcohols containing at least one ether oxygen atom, comprises copolymerizing (1) 2% to 50% by weight of the monomers of an ester of an a , b -ethylenically unsaturated carboxylic acid and a saturated aliphatic or cylcoaliphatic alcohol having one alcoholic hydroxyl group and at least one ether oxygen atom in the molecule with (2) 98% to 50% of a further ethylenically unsaturated monomer, while in contact with a Redox catalyst system comprising a free-radical-forming catalyst and a reducing agent therefor which is present in molar excess by comparison with the radical-forming catalyst.  Emulsifiers, e.g. fatty acid salts, alcohol sulphonates, aryl alkyl sulphonates and alkyl phenol-ethylene oxide condensates, may be present.  Specified unsaturated acids are acrylic, methacrylic, a -chloracrylic, maleic, fumaric and citraconic acids. The alcohol may be a partial ether of a polyhydric alcohol, many examples being listed. The comonomer may be an ester of acrylic, methacrylic, a -chloracrylic, maleic or fumaric acids, acrylonitrile, vinyl chloride, vinylidene chloride, vinyl ester, vinyl aromatic hydrocarbon or conjugated diene.  The free radical catalyst may be a peroxide or azo compound and the reducing agent an oxidizable sulphur or phosphorus compound, tertiary amine, a -ketol or endiol or water-soluble metal salt, many examples of catalyst components being listed.  Examples describe the copolymerization of (1) 3-methoxybutyl acrylate, butadiene and acrylonitrile in the presence of potassium persulphate, sodium pyrosulphite, lauryl sulphonate and n-dodecyl mercaptan; (2) 3-methoxy-butyl acrylate, butadiene and styrene in the presence of cumene hydroperoxide, sodium formaldehyde sulphoxylate, lauryl sulphonate and n-dodecyl mercaptan; (3) 3-methoxybutyl methacrylate, styrene and butyl acrylate in the presence of potassium persulphate, sodium pyrosulphite and oleyl sulphonate; and (4) 3-methoxybutyl acrylate, ethyl acrylate, acrylonitrile and styrene in the presence of potassium persulphate, sodium pyrosulphite and lauryl sulphonate.  The reaction may be stopped by adding hydroquinone and the polymer protected from premature oxidation by adding phenolic compounds, e.g. phenol, hydroquinone, pyrogallol, 1, 2, 4-tertiary butyl pyrocatechal or 2, 21-methylene bis(4-methyl-6-cyclohexyl phenol).  The polymers may be cross-linked by air, preferably in the presence of peroxides or metal driers, e.g. cobalt, iron, copper, manganese, chromium calcium, nickel or lead naphthenates, and may be used for coating paper, wood, textiles and leather.

Abstract: 734,322. Fastenings. ELSNER, E. C. May 11, 1953 [May 15, 1952]. No. 13040/53. Class 44. A fastening device comprises an elongated channel 38, Fig. 1, having two spaced flanges 40, 41 and a back member 50 forming a T-slot 39 having a first wide slot and a second narrow slot, both extending through the length of the channel, the second slot being formed between the flanges 40, 41 and the first slot being defined by the space between the flanges 40. 41 and the back member 50, a connector adapted to be inserted into the channel which connector comprises a pin 48, Fig. 3, a bar member 22 on one end of the pin the bar member 22 being insertable through the second slot and forming interconnecting engagement with the first slot upon turning of the bar member 22 into the first slot, a cupped member 43 mounted on the connector for locking the bar member in said engagement, the cupped member having means for engaging the channel through the second slot for obtaining said locking, and a fastening ring 49 connective to the other end of the pin 48. The ring 49 may serve as a cargo fastening ring which can be secured at selected points along the channel 38. The flanges 40, 41 are provided with spaced notches 42, which can receive end edges 47, Fig. 2, of the cupped member 43. The ring 49 is carried by a section 14 pivotally mounted by the pin 48 on a section 13 which is formed with the bar member 22. An elongated shank 45 on the upper side of the section 13 slidably fits in a corresponding slot in the cupped member 43 which is rotatable on the section 14. This shank 45 is disposed at an angle relative to the bar member 22 (see Fig. 4) and is parallel with the backs of slots 23 formed in opposite corners of the member 22. A spring 46 urges the member 43 downwardly on to the shank 45. When the bar member 22 is inserted in the slot between the flanges 40, 41 the edges 47 of the cupped member are out of alignment with the opposite notches 42 and can thus ride on top of the flanges 40, 41. However when the bar member 22 is rotated by rotating the cupped member 43 whilst at the same time the section 14, is depressed, the bar member will engage underneath the flanges 40, 41, owing to the provisions of the slots 23. The edges 47 will then be aligned with the notches 42 and the spring 46 will urge the cupped member 43 downwardly and thus the edges 47 to engage in the notches and interlock the parts against release. To release the fastening it is necessary only to raise the member 43 to release the edges 47 from the notches 42 and then turn, whereupon the bar member 22 will be aligned with the slot between the flanges 40, 41.

Title: Improvements in and relating to Automatic Lathes and like Machines.
Inventor: POTTER JAMES CHARLES
IPC: B23B7/14
Filed: 1916-09-22
Abstract: 109,660. Potter, J. C. Sept. 22, 1916. Lathes.-Automatic turret lathes and like machines have motions such as the turret and crossslide feeds, the back-facing bar mechanism, and the dog wheels for operating speed controlling and reversing mechanism, all operated in sequential relation from a common back shaft as controlled by a mechanism of the counter type. As applied to driving the pinion 30, Fig. 7, meshing with the turret feed rack, the back shaft 25, drives in opposite directions gears 53, 54 loose on the shaft 59 and meshing with gears 60, 61 loose on a sleeve 66, Fig. 11, of the counter mechanism, and carrying arms 62, 63 forming part of Geneva mechanisms 71, 72 for indexing a cam shaft 74, Fig. 6. in either direction. The cam shaft 74 through a lever 80 and yoke 83 controls a clutch 58 having three positions corresponding to forward and return feeds and dwell of the turret, and imparting drive to the shaft 59 from the gea.rs 53, 54 and thence through worm gear 91 to the pinion 30. A handoperated clutch 93, Fig. 7, provides for throwing out the power feed and feeding by a pilot wheel 94, for example during setting up. To lock the clutch 58 in the neutral position, notches 87 in it engage a fixed bowl 88. Counter dials 114, 113, 112, Fig. 11, each have two sets of ten holes to receive pins 116, 119, Fig. 12, co-acting with cam lugs on bars 69, 70 respectively. The lugs are so spaced that in the initial position only the pins in the dial of highest denomination are in the path of a lug. When the dial is indexed to the set position, the pin cams the bar forward bringing the next lug into the path of the dial pins of the next denomination. Finally, the pins in the unit dial cam the bar, by this time in contact with the gear 60, or 61 according to the sets of pins in operation, to slide the gear and render the Geneva mechanism operative to index the cam shaft 74 one step. A similar mechanism is applied to the cross slides which are arranged to swivel about the shafts, Fig. 4, of the bevel-gear train transmitting drive to the feed-screws. Other similar mechanisms control the dog wheels 137, Fig. 1<a>, acting through the lever systems 153. 146 to control the feed and spindle change-gear clutches 148, 155. Projections on the side of the dog wheels maintain the clutches in action when closed by the counter mechanisms until the wheels have been indexed one division. If it is desired to index through several divisions, filler blocks are inserted between the necessary number of projections. Hand-levers 98, Fig. 6, provide for maintaining the arms 80 in an inoperative position when desired. The counter control mechanisms are built up as complete units detachable as a whole from the machine. If a complete cycle of operations does not make use of all the index positions provided, the machine may be set to index idlv through the remaining positions at the end of the cycle, thus providing time for removal and replacement of work.
