Abstract: Low molecular weight copolymers of vinyl compounds with compounds of the formula: <FORM:0712220/IV (a)/1> wherein R1 and R2 are hydrogen, halogen, lower alkyl, aryl or aralkyl groups, and X is oxyalkyl or oxyaryl, are prepared by refluxing the dicarboxylic acid compound in solution in an inert organic solvent-diluent in the presence of a peroxide catalyst, at a temperature above the boiling point of the vinyl compound and slowly adding the vinyl compound, which may be in solution, at such a rate that the dicarboxylic acid compound is in excess throughout the major portion of the polymerization.  The dicarboxylic acid compounds may be maleic, ethyl maleic, phenyl maleic, benzyl maleic, dibenzyl maleic, chloromaleic and citraconic anhydrides and maleic acid ethyl ester, phenyl maleic methyl ester, chloromaleic propyl ester and citraconic butyl ester.  Specified vinyl compounds are methyl, ethyl, isopropyl, n-propyl, isobutyl and butyl vinyl ethers, vinyl chloride, bromide, acetate and formate, acrylic acid, and methoxyethyl vinyl ether.  The peroxide catalyst may be acetone, acetyl, benzoyl, butyryl, lauroyl or succinyl peroxide or tertiary butyl hydroperoxide.  The boiling point of the solvent-diluent must be above that of the vinyl compound and alkanes, cycloaliphatic or monocyclic aromatic hydrocarbons, or mixtures thereof in which the copolymer is insoluble may be used, if desired mixed with an equal amount of acetone methyl ethyl ketone or isoprobyl methyl ketone. A list of solvent-diluents is given. Alternatively a ketone solvent, in which the copolymer is soluble, may be used alone and the copolymer isolated by precipitation with a hydrocarbon non-solvent.  The powdery products have a specific viscosity of 0.02 to 1.2 and may be used in stuffing leather and in adhesive compositions.  U.S.A.

A speed-indicating apparatus comprising a differential gear having two elements adapted to be rotated at constant and varying speeds respectively and a third element the movement of which represents the difference in the rotational speeds of the first two elements is characterized in that the output element of the differential gear is connected to the main spindle of a counter mechanism having two sets of numeral wheels, adapted to indicate respectively the amount " fast " or " slow," in terms of time, by which the varying-speed driving element has departed from a desired pre-set average speed. An electric motor 13 drives a gear-wheel 24, Fig. 1, through the gearing 15, 16, 18, 19, 23 at a constant speed determined by an escapement mechanism, Fig. 2 (not shown). The gear-wheel 24 is free on a shaft 25 and carries two intermeshing planet wheels 34, 35, Fig. 3, which mesh respectively with gears 36, 37. The gear 36 is fixed to the shaft 25 and is driven through the gear train 38 ... 42, Fig. 1, and a variable speed gear comprising a roller 66, two balls 69, Fig. 5, and a disc 65 driven from a shaft 43, Fig. 1, the speed of which is proportional to the vehicle speed. The output gear 37 of the differential is connected through a sprocket and chain and a dog clutch 56 to the input shaft 50 of a counter 47 having two sets of numeral wheels 48, 49. The arrangement is such that the numeral wheels 48, 49 respectively indicate by how many minutes the vehicle is " slow " or " fast " with respect to the desired average speed as pre-set by the variable speed gear, the balls 69 of which are carried by a block 67 adjustable radially of the disc 65 through manually controlled means comprising a knob 74, a screwed spindle 75 and an arm 76 of the block 67. The block 67 carries a pointer 77 which is set to the desired graduation on the scale 78. The mechanism is within a housing having a transparent cover 12. To zeroize the counter 47 the knob 52, Fig. 4, is depressed to open the dog clutch 56 through the bell-crank lever 53 and a plunger 54 and to bring a contrate wheel 57 into mesh with a pinion 58 on the spindle 50 and the knob 52 is then rotated.

Abstract: 1294328 Direct positive silver halide emulsion production EASTMAN KODAK CO 3 Nov 1969 [1 Sept 1969] 24714/72 Divided out of 1294327 Heading G2C A direct-positive silver halide emulsion is prepared by a method including partially reducing a water-soluble silver salt to silver with a reducing agent and then reacting the remaining silver salt with a water-soluble halide. The reducing agent may be stannous chloride, thiourea dioxide, formalin or an alkaline arsenite reducing agent. Polyvinyl pyrrolidone may be added to the silver salt before reduction to obtain high contrast and maximum density with a small silver halide coverage. The silver halide grains formed may be chemically fogged. The material having a direct-positive emulsion prepared as above may contain nitron in at least one layer. The directpositive material may contain silver halide which is predominantly bromide and an overlayer which contains ions which are displaced by bromide ions, e.g. a desensitized (i.e. having a photographic speed at least ten times less than the image-forming silver halide layer) silver chloride emulsion layer. The silver halide emulsions of this invention comprise silver halide grains containing centres which promote the deposition of photolytic silver which are provided by the partial reduction of the silver salt. Direct-positive materials containing nitron are described and claimed in the Specification No. 1294327 (Serial No. 24714/72.)

[Class 35] [Also in Group XXIX] In an electromagnet in which a movable armature is pulled into a solenoid (e.g. for operating a hydraulic valve), the non-magnetic sleeve in which the armature moves is welded or brazed to the core to make a fluid-tight joint. In Fig. 1, the armature 4 which moves poppet valve 6 off its seating 10 against the force of spring 7 when coil 8 is energized, slides in the non-magnetic tube 3 which is secured to the magnet core 1 by welding or brazing at 2 to form a joint sealed against the pressure of the fluid passing through the valve. The seating 10 can be adjusted lengthwise in the body 12 and locked in place by circlip 14; the seal 11 forms a fluid-tight joint. The magnetic circuit is completed by the outer sleeve 9 and includes the seating 10. In a modification, the seating is not part of the magnetic circuit and the magnet, when energized, opens a normally closed valve.

Abstract: The invention comprises dyes of formula: <FORM:0844353/IV (c)/1> where R is a benzene residue containing an SO3H or COOH group or a COOH group with an OH group in #s-position thereto, A for a symmetrical triazine residue in which three halogen atoms originally attached to carbon atoms have been replaced by B, C and Z, Z is Hlg, OH or NH2 which may be mono- or di-substituted and one X is H or Cl and the other H, F, Br or Cl but the two X's may not be two different halogens.  They are made by condensing a triazine trihalide with appropriate azo and anthraquinone dyes and, if desired, replacing the remaining triazine halogen atom by hydroxy or amino groups. Preferred are dyes in which both X's are H, Z is Cl, OH, HN2 or phenylamino, and R is a 3- or 4-sulpho- or 3-carboxy-4-hydroxy-phenyl group.  Cyanuric chloride and bromide are specified halotriazines. Illustrative of amines for reaction with the third halo triazine atom are aniline and its sulphonic and carboxylic acids, 1-amino -4- acetylaminoben zene, N-methylaminobenzene, and methyl-, di-methyl-, ethyl-, diethyl- and mono- and di-ethanolamines.  The dyes dye cotton and fibres of natural or regenerated cellulose in green shades. Cellulose acetate is reserved.  When Z is a halogen atom a dyeing process may be used which causes the dye to react with the cellulose residue.  Materials dyed with a dye containing an #s hydroxy-carboxy grouping may be aftercoppered.  Examples are given of the preparation of the dyes and their use in dyeing processes. Specification 657,753 is referred to.
