Title: Improvements in and relating to the manufacture of silica-pigmented rubber articles
IPC: C08K3/34
Filed: 1959-07-27
Abstract: Vulcanized rubber of high resistance to abrasion and low flexural heat build-up is made from a mixture of a minor proportion of a silicon oxide pigment, a major proportion of a butadiene styrene copolymer and a minor proportion of a vulcanizing agent of structure R-S-S-NR1 (R2), where R is a thiazole radical of 3 to 14 carbon atoms and R1 and R2 are aliphatic, cycloaliphatic and aralkyl radicals and radicals wherein R1 and R2 are joined to form a single alicyclic or heterocyclic ring.  Preferably, the vulcanizing agent has the structure in which R1 and R2 each represent an aliphatic group of 1-4 carbon atoms, a cycloaliphatic group of 5-6 carbon atoms, an aralkyl group of 7-10 carbon atoms, an aliphatic group of 2-5 carbon atoms in which R1 and R2 are joined together, or represent alkylene groups of 1-4 carbon atoms joined together through a chalcogen atom having atomic weight less than 33.  The vulcanizing agent is exemplified by 2-benzothiazyl-N- morpholinyl and -N-thiomorpholinyl disulphides. Vulcanization is at 260-320 DEG F. The silicon oxide pigment may be fibrous monox (SiO2)x (Si)y, where x and y are substantially the same, arc silica, fume silica, silicon oxymide, precipitated silica, precipitated calcium silicate, silica gel, pulverized silica gel, silica aerogels, clay, natural and synthetic silicates.  The pigment is preferably of particle size 1-700 millimicron and of surface area 25-900 sq.m./g.  A typical mixture for vulcanizing comprises 25-45% of fibrous monox and 75-55% of a 55-85% butadiene-45-15% p  styrene copolymer with 3-6 parts, based on the combined weight of pigment and rubber, of the vulcanizing agent.  Mixing is preferably carried out in an inert atmosphere; to assist in maintenance of non-oxidizing conditions during mixing a polyamine having NH2 groups attached to an aromatic nucleus may be incorporated.

Title: Copper-containing polyazo dyestuffs
IPC: C09B33/18
Filed: 1957-08-15
Abstract: The invention comprises the copper complexes of polyazo dyestuffs of formula <FORM:0820472/IV(c)/1> wherein R and R1 are radicals, the same or different, of a coupling component bearing the hydroxyl group in ortho-position to -N=N-, Z is an azo or azoxy group and X is hydrogen or a sulphonic acid group.  The copper complexes are obtained by diazotizing aminonitronaphthalenes of formula <FORM:0820472/IV(c)/2> coupling with azo components coupling ortho to an hydroxy group, oxidizing coppering the azo dyes thus obtained (e.g. by treatment with copper sulphate and hydrogen peroxide) and then reducing the coppered nitrogen compounds in known manner (e.g. with glucose in aqueous caustic soda) so that 2 molecules are linked by an azo or azoxy group.  Alternatively the complexes may be prepared by linking the uncoppered nitrogen compounds by reduction and oxidizing coppering the polyazo dye thus obtained.  Finally the copper complexes may be obtained by tetrazotizing compounds of formula <FORM:0820472/IV(c)/3> wherein Z and X are as defined above, coupling with the same or different azo components which couple ortho to an hydroxy group and oxidizing coppering the polyazo dye so obtained.  The copper complexes dye cellulose fibres in blue or grey shades.  Specified p  coupling components include acetoacetanilide, phenols, naphthols, naphthol-sulphonic acids, aminonaphtholsulphonic acids, 1-(sulphophenyl or -naphthyl)-3-methyl-5-pyrazolones, 1-phenyl-3-carboxy-5-pyrazolone, 4-hydroxy-azobenzene-41-sulphonic acid and 1-hydroxy-3-sulpho-5-chloronaphthalene - [6 : 11] - azo - 21 - naphthol - 31 : 61 - disulphonic acid.

Filed: 1947-09-23
Abstract: 636,146. Autographic registers. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. Sept. 23. 1947, No. 25854. Convention date, Dec. 7, 1946. [Class 16] [Also in Group XVI] A printing machine which is especially applicable for printing sales slips in an autographic register, is arranged so that a pivoted printing member 65 is adapted to support a name plate 75 supplied by a customer, and the machine will only operate if the correct name plate is inserted. The printing- machine as a whole is attached to a writing tablet 34, Fig. 5, and by removing the writing-tablet of an autographic register of known kind, the mechanism as a whole can be attached to the register. The record strips S are fed over the tablet 34 below a writing aperture formed in the pivoted top portion 25b of the machine casing, and an inked ribbon 36 is led from a roll 37 transversely between two sheets S, and remains in position until a new surface is required, when the ribbon is pulled through by hand and the worn ribbon discarded. The member 65 is formed with channels to receive lugs on printing-plates to print fixed data, and with lugs 72, 73, Fig. 8 to receive the nameplate 75 which is formed with a series of notches 200, 200A, 200B, &c., Fig. 1, to enable the operator to check the correctness of the plate visually, and one notch 200F co-operates with a pin 202 on the member 65 which permits only authorised plates to make an impression since the plate 65 cannot be moved to printing position if the plate extends beyond normal position. The plate 65 is pivoted to its supporting brackets by eccentrically mounted screws 70, and when moved down into printing position by hand operation of an extension 79 it is locked in position by spring catches 94, 95 also mounted on eccentric screws 101. Adjustment of the screws 70, 101 permits printing of a variable number of copies at a time. The impression member is a roller 110 mounted on posts 111, 112 carried by a pivoted arm 50 having an operating extension 109 which passes through a slot in the front of the casing. After the roller 110 has pressed the slips S and ink ribbons against the type members, it acts on a bumper 130 which releases the catches 94, 95, and a spring 105 raises the type member 65 out of the path of the roller 110 as it is returned to its initial position and so avoids shadow printing.

Filed: 1924-10-31
Abstract: 242,775. Beasley, E. G., and Deacon, H. S. Oct. 31, 1924. Yarn supply ; bobbin stands.-An initial tension put on the yarn as it passes from a full bobbin is automatically and progressively reduced to compensate for the normal increase in tension due to the supply becoming exhausted. It is stated that stockings and other articles can thus be knitted of a more nearly uniform length and texture than would otherwise be the case. The bobbin is mounted on a plate 7 fixed to a rod 9 slidable vertically in a bearing on a frame 1. This frame is adjustably attached by an arm 2 and screws 3, 6 to a rod 4 of a bobbin carrier 5 of usual type. The weight of the bobbin &c. compresses a spring 12. As the yarn is drawn off, the plate &c. 7 moves up and also pushes up a rod 16 by engagement of an arm 13 under a stop 14, the parts 13, 14 sliding on a rib 17. The upper end of the rod 16 passes through the frame 1 and is provided with a stop 18, a pin 20 on which engages under an arm 21 on a swinging bar 23 pivoted at 25 in the frame. The bar has a number of fingers 22 having yarn eyes 24 and alternating with stationary lugs 26 having eyes 27. The yarn is threaded through the eyes, and as the, supply is reduced the bar 23 is rocked to relieve the initial tension due to the weight of the bobbin &c. In a modified construction, self-threading yarn forks are used in place of the guide eyes 24, 27.

Abstract: 631,298. Exciting dynamo-electric machines. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. Oct. 3, 1947, No. 26679. [Class 35] In order to provide a quick response to changes in the current controlling the excitation and thus the output of a D.C. generator 20 the field winding 31 of the latter is separately excited from a H.F. alternator 21 through a saturable transformer 25 or saturable reactor (not shown) and a bridge rectifier 30. A condenser 23 associated with the self-inductance of the alternator 21 forms a Bouchent circuit which gives constant current to a bridge rectifier 33 which in turn gives constant D.C. to the auxiliary winding 34 of the saturable transformer 25. The latter also carries a main control winding 29 which, when its flux due to the current flowing therein, is opposed by the flux due to the current in winding 34, the sense of the control is reversed, so that the D.C. generator 20 has its output increased with increasing current in the winding 29.
