Title: Improvements in yarn winding machines
IPC: B65H54/38
Filed: 1944-10-07
Abstract: 586,069. Winding yarn. ARUNDEL, COULTHARD, and CO., Ltd., BATEMAN, L. H., and BURGESS, C. O. Oct. 7, 1944, No. 19253. [Class 120 (ii)] In a yarn winding machine of the drum-driven type, the traverse of the yarn being effected by the drum, or otherwise, means are provided for slightly and intermittently easing the driving pressure between the package and the drum so to destroy the harmony between the rate of rotation of the package and the rate of reciprocation of the yarn across the package. Yarn g, from supply, is led around a tensioning device h, through a detector i, then about a pin and traversed on to the package a by two grooved rollers k, f. The package a is carried by a cradle d pivoting about a rod e, the cradle d being slightly raised periodically, to ease the pressure of the package a on the driving roller f, by the rotation of an eccentric x which oscillates a frame w about a spindle v, this oscillation, through an arm u lifting a rod t, forming part of an oil dash pot device, lifting a rod m attached to the cradle d. The bottom of the dash pot cylinder n is pivoted at 2 to an arm y latched to the frame w by a spring catch z. A wide fork 3, forming part of a weighted lever 4, embraces the pin 2, the lever 4 being supported by a detector box member 5 If the yarn g fails or breaks, the detector i falls into the path of a rod 10, oscillated by the frame w, the detector box member 5 is moved to the right to release the weighted lever 4, and the spring-urged levers 7, 8 push the catch z from the frame w, to allow the cylinder n and rod m to be raised thus lifting the package a clear of the drum f. The connections to the dash pot comprise a coned collet or split sleeve r on the rod m the collet being moved by the rod t, a coned top cap s being fitted to the cylinder n. On normal winding, movement of the rod m, to ease the pressure of the package in the drum, takes place through the dash pot but upon thread breakage or failure, the coned portion of the cap s is raised to contact the coned collet r to lift the package completely from its driving drum. Specifications 399,546, 569,765 and 580,989 are referred to.

Abstract: 948,059. Moulding plastic materials such as dough. T. & T. VICARS Ltd. June 3, 1960 [June 6, 1959], No. 19409/59. Heading B5A. A machine for moulding, embossing and/or cutting plastic materials, e.g. dough, and embodying air-assisted ejection of the treated material comprises a roller having one or more dies located about its periphery and with the side wall of the or each die projecting from the surface of the roller to form a cutter shell, the bottom wall of the or each die constituting a surface for receiving the plastic material directly thereon and being micro- or macro-porous. The porosity of the dies allows unobstructed passage of the ejection air but the pores are too small to allow the plastic material to enter and block them. In the embodiment illustrated, an embossing and cutting roll 10 of a machine for treating dough is mounted for rotation on a power-driven shaft 11 and carries a plurality of cutter shells 13 around its periphery, each shell having an embossing die 14 formed from a micro- or macro-porous material at a depth determined by the thickness of the dough sheet to be embossed and cut. The dough sheet is led, e.g. on a conveyer or over a table, beneath the rotating roll 10. Roll 10 comprises a series of chambers 17 each having an aperture 21 at one end and apertures 18 beneath each die 14. A stationary annular air supply box 19 is located around shaft 11 at one end of roll 10, being urged against the end face of the roll by a spring 22. Box 19 has a single opening in the form of an arcuate slot 20 in the face which is urged against the roll 10 and this slot is successively brought into register with each of the apertures 21 as the roll 10 rotates. The slot 20 is positioned such that communication between a source of compressed air connected to inlet pipe 23 and the dies 14 is made as the latter retract from the dough sheet so that the cut sections contained within the cutter shells 13 are ejected.

Inventor: JACKSON WILLIAM MORRISON
IPC: B01J41/04
Filed: 1965-05-07
Abstract: The invention comprises magnetic sols of g Fe2O3 which are stable for at least two months and which show no increase in size as determined by electron microscopy.  The sols may contain up to 38% by wt. g Fe2O3 of particle size 3-12 mm  and the continuous phase may be water or a non-polar organic liquid, e.g. toluene. Stable aquasols are prepared by (a) adding, preferably in an inert atmosphere, an aqueous solution of ferric and ferrous salts of a monovalent anion (e.g. Cl-,NO3-) in which the molar ratio Fe (III): Fe (II) is 3:1 to 1:1 and the total concentration of Fe is 0.5-3M, to an agitated slurry of an anion exchange resin of the strong base type in the OH form present in an excess of 3-200% by volume of the anions to be removed, such that the pH is maintained at 7.5 to 9.5, (b) stabilizing the sol by reducing the pH to 1-3 rapidly by adding a mineral halide and/or an acid.  The sol may be dialysed at 10-30 DEG C. to form a gel which may be separated form excess water and redisposed in water at pH 1-3 to give an aquasol of increased concentration or contacted with a lyophilic transfer agent (e.g. ammonium oleate) in an organic liquid to form an organosol.  Solid hydrated g Fe2O3 may be prepared from the aquasol by (a) evaporating the sol in air, (b) adding alkali until the pH is 3.8 or (c) adding MgSO4 and drying the precipitate of Fe2O3 in each case at up to 200 DEG C.

Filed: 1932-07-11
Abstract: Carbocyanine dyes derived from an azole base of the formula:--<FORM:0396217/IV/1> wherein R is a residue of anthracene phenanthrene, acenaphthene, fluorene, chrysene, carbazole or diphenyleneoxide, are prepared by treating a quaternary ammonium salt of a thiazole base of the above formula with a trialkyl orthocarboxylic acid ester.  In examples (1) 2-methyl-b -anthrathiazole-diethyl sulphate is heated in pyridine with triethylorthopropionate at 130 DEG  C., and 1.1<1>-diethyl-ms-ethyl-b -anthrathiocarbocyanine bromide precipitated by adding potassium bromide: (2) by similar means 1.1<1> - diethyl - ms - ethyl - a  - anthrathiocarbocyanine bromide is prepared from 2-methyl-a -anthrathiazole diethylsulphate, (3) 1.1<1>-diethyl-carbazolethiocarbocyanine chloride from 2-methylcarbazole diethyl sulphate using triethyl orthoformate and sodium chloride, (4) 1.1<1>-diethyl-ms-methyl-acenaphthenethiocarbocyanine bromide from 2-methyl-acenaphthenethiazole-diethyl sulphate, and (5) 1.1<1>-dimethyl-ms-methyldiphenyleneoxidethiocarbocyanine chloride from 2-methyl-diphenyleneoxidethiazoledimethyl sulphate using triethyl orthoacetate in the two latter cases. Specification 232,740, [Class 2 (iii), Dyes &c.], also is referred to.  Thiazole bases corresponding to the above formula are prepared by converting an amino compound of anthracene, phenanthrene, acenaphthene, fluorene, chrysene, carbazole or diphenyleneoxide into the acetyl derivative, and the latter into the corresponding thioaceto compound which is then oxidized by potassium ferricyanide.  Thus in an example acetyl-a -anthramine is treated with phosphorus pentasulphide and the product oxidized by alkaline ferricyanide to 2-methylanthrathiazole.  The following alternative methods of preparing the bases are also given: 9-benzoyl-3-aminocarbazole is converted into 9-benzoyl-2-amino-carbazolethiazole according to the process of Specification 295,295, [Class 2 (iii), Dyes &c.], and this compound saponified as indicated in Specification 306,590, [Class 2 (iii), Dyes &c.].  The o-mercaptoaminocarbazole obtained is treated with glacial acetic acid and acetic anhydride to give the 2-methylthiazole compound: (2) a similar series of operations applied to 2-aminodiphenyleneoxide gives the corresponding 2-methylthiazole derivative.  These bases are converted to their quaternary salts by the known methods.  The Specification as open to inspection under Sect. 91 relates to the manufacture of carbocyanine dyes by treating a quaternary ammonium salt of an azole base of the formula: <FORM:0396217/IV/2> wherein Y is sulphur, oxygen or selenium, and R is a residue of anthracene, phenanthrene, acenaphthene, fluorene, chrysene, carbazole or diphenyleneoxide each of which may contain one or more substituents, with a trialkyl orthocarboxylic acid ester or a tetraalkyl orthocarbonic acid ester.  This subject-matter does not appear in the Specification as accepted.

Title: Method of preparing carbon-base pastes
IPC: C25C3/12
Filed: 1949-07-28
Abstract: Carbon pastes, for the manufacture of electrodes and the internal linings of electric furnaces and electrolytic cells, and made from carbonaceous material of various sizes and a binder, e.g. pitch, are prepared by separating the carbonaceous material into a coarser and a finer fraction, the former constituting 30-75 per cent of the whole, mixing the coarser fraction with the binder until all the particles are substantially wetted, adding the finer fraction, and continuing the mixing until the mass is fully homogeneous.  If the carbonaceous material is porous, the finest particles of the coarser fraction are similar in size to the pores of the largest particles; if the pores in the material are comparatively small, the smaller particles of the coarser fraction should be approximately 0.2 mm. in size.  The binder is preferably used in liquid condition and the coarser fraction may be first mixed only with a part of the binder, the remainder being added with the finer fraction; alternatively, the coarser fraction may be mixed with the binder in solid condition, the binder being liquefied by heating before the fine fraction is added.
