Title: Improvements in or relating to the manufacture of organic sulphur compounds
IPC: C07D277/36
Filed: 1941-02-19
Abstract: 547,255. Mercaptothiazoline derivatives. DU PONT DE NEMOURS & CO., E.I., STURGIS, B. M., and VERBANC, J. J. Feb. 19, 1941, No. 2247. [Class 2 (iii)] Homologues and derivatives of 2-mercapto- 4:5-thiazoline containing aliphatic substituents in one or both of the 4- and 5-positions are prepared by reacting carbon disulphide with an amino-aliphatic alcohol, other than ethanolamine, containing a single amino group bonded to a carbon atom adjacent to that carrying an hydroxyl group, under superatmospheric pressure and at a temperature above 120‹C., preferably by heating in a closed vessel to a temperature of from 130‹ to 170‹C. The carbon disulphide is usually in excess, advantageously 2 to 3 mols. per mol. of amino-alcohol. A solvent, such as water or an alcohol, may be employed, and basic materials, such as ammonia or the hydroxides and carbonates of alkali and alkaline earth metals, may be present. The products are useful as vulcanization accelerators. Examples describe the preparation of 2- mercapto-4:4-dimethylthiazoline using 2-amino- 2-methyl-1-propanol, 2-mercapto-4-ethylthiazoline using 2-amino-1-butanol, 2-mercapto-4- methylthiazoline using 2-amino-1-propanol, 2- mereapto-4-methyl-4-ethylthiazoline using 2- amino - 2 - methyl -1- butanol, 2 - mercapto - 4 - propylthiazoline using 2-amino-1-pentanol, 2- mercapto-4:4-dimethyl - 5 - methylthiazoline using 3-amino-3-methyl-2-butanol, 2-mercapto- 5:5- dimethylthiazoline using 1-amino-2- methylpropanol-2, and 2-mercapto-4-methyl- 4-hydroxymethylthiazoline using 2-amino-2- methyl- 1:3-propanediol.

Title: Improved retractor for safety belts
IPC: B60R22/41
Filed: 1970-01-16
Abstract: 1280443 Seat belt inertia reel JIM ROBBINS SEAT BELT CO 16 Jan 1970 [7 April 1969] 2337/70 Heading A3V A safety seat belt retractor includes means for moving a locking member towards a locking position when the belt 40 is unwound with an acceleration greater than a predetermined value, such means being operable only when the reel 30 and belt 40 have been unwound and subsequently slightly rewound to a position outside a predetermined range of positions. The pin 62 of a locking pawl 44 engages a slot in plastics clutch member 52 and the pawl is normally biassed by a magnet (80) to a release position in which it does not engage the teeth of ratchets 34, 36. The engagement of a cut-out portion 70 of member 52 by an arm 72 of stop 68 normally holds the pawl in the release position but when a spiral cam track 76 and follower 66 sense that the reel has been rotated from the fully wound position by more than a predetermined interval, the follower 66 disengages from loop 78, and upon slight retraction of the belt allows leaf spring 74 to move the arm 72 past projection 82 of cut-out 70. If now the belt is unwound at an acceleration greater than a predetermined value, a steel clutch member 54, which acts as an inertia member and has cam surfaces (86), (88) cooperating with a radial pin 84, biasses the clutch member against and into frictional entrainment with the ratchet 34 thus moving the pawl 44 into a locking position to stop further belt extension.

Patent GB-373166-A (GB)
Title: Briquet and method for producing same
IPC: C21B5/00
Filed: 1931-02-18
Abstract: Fuel briquettes are obtained from coal purified by amalgamation with a liquid hydrocarbon in the presence of water which is subsequently separated, and metallic substances such as iron oxide or iron sponge are added, the mixture being distilled to remove residuary water and light fractions of the oil, before being charged into a blast furnace.  Iron ore should be first concentrated and washed before use in the amalgam, which may consist of 75 per cent coal, 15 per cent oil, and 10 per cent water, and the ore concentrates and amalgam are mixed in about equal proportions before distillation at about 600 DEG F., which removes about 50 per cent of the oil.  The distilled mixture is briquetted and carbonized at red heat, the oil residue being converted into coke.  Sponge iron may be converted into pigiron by being briquetted with the carbonaceous material, and heated to melting, when it absorbs about 2 per cent of carbon.  A desulphurizing agent such as limestone may be added, which acts also as a fluxing agent, calcium sulphide being formed.  The desulphurizing and fluxing action of the limestone is completed in the blast furnace.  A suitable oil for use is low temperature tar oil.  If bituminous coal is used it should first be distilled at 1100-1200 DEG  F. to give low temperature coke and tar oil for use in the process.  Specification 151,236, [Class 50, Fuel, Manufacture of], is referred to.  The Specification as open to inspection under Sect. 91 (3)(a) describes also the manufacture of briquettes from ore concentrates and tar oil or petroleum oil, the ore and oil being mixed in about equal proportions, and the mixture being distilled to remove about 50 per cent of the oil and leave an asphalt residue. This subject-matter does not appear in the Specification as accepted.

Filed: 1971-01-20
Abstract: 1384373 Temperature measurement UNITED KINGDOM ATOMIC ENERGY AUTHORITY 20 April 1972 [20 Jan 1971] 2825/71 Headings G1D D34 D37 and D43X A method of measuring temperature, or a weighted mean value of temperature over a given period, comprises locating in the measurement zone two different materials in contact with each other, the materials being solid at the maximum temperature likely to occur, and determining the change in concentration of one material in the other at the end of said period. The rate of diffusion is a function of temperature. The change in concentration may be determined by sectioning one or both of the materials and analyzing their composition, e.g. by employing radio-active tracer methods, or by measuring the change in electrical resistance of one or both of the materials, or if one of the materials is ferromagnetic, measuring changes in magnetic properties due to diffusion of the other material in the ferromagnetic material. When electrical resistivity is measured, preferably one material is deposited as a coating on a wire of the other material. When magnetic properties are measured, a foil of non-magnetic material is welded to the surface of a sheet of ferromagnetic material. Examples of suitable pairs of materials are listed in the Specification.

Patent GB-639908-A (GB)
Title: Improvements in and relating to machines for the production of artificial fibres from viscose
IPC: D01D5/00
Filed: 1948-02-04
Abstract: A spinning machine for the production of artificial fibres from viscose has a spinning zone closed off by a number of windows each of which can be opened and closed independently by hand and all or a set group of which can be opened or closed by fluid pressure-operated mechanism, irrespective of whether or not one or more of the windows have previously been opened or closed independently by hand.  As shown, one closed window 1, Fig. 1, of a number of windows constructed in the same way and mounted on a common shaft 2 about which they can rotate, is opened manually by lifting it outwardly and upwardly by means of the handle 4.  As this is done the small roller 16, Fig. 3, carried on the arm 13, Figs. 1 and 3, fixing the counterweight 3 to the window 1, travels down the edge 17 of the plate 11, Figs. 1 and 3, bolted to the shaft 2, towards the shaft 2, so pulling the slot 14, Fig. 3, along the peg 12, Figs. 1 and 3, fixed to the plate 11, until, at the fully raised position shown in Fig. 4 the peg 12 will be at the end of the slot opposite to that which it <PICT:0639908/IV (a)/1> <PICT:0639908/IV (a)/2> <PICT:0639908/IV (a)/3> <PICT:0639908/IV (a)/4> <PICT:0639908/IV (a)/5> originally occupied.  As a result, the centre of gravity of the combined window 1, Fig. 1, and counterweight 3 (which lies at about the centre of the slots 14) is transferred from one side of the pegs to the other; the counterweight 3 will then rest on the roof of the spinning zone or against a suitable stop and the window will remain open.  When the window is lowered manually the process is reversed.  To open the windows by fluid pressure one side of the piston 5, Fig. 2, is connected to a source of hydraulic pressure which forces the piston to the opposite end of the cylinder and rotates the shaft 2, Fig. 1, clockwise by means of a hinged connecting rod 6, Fig. 2, and a crank 7 bolted to the shaft by a bolt 8.  The leverage exerted by the peg 12, Fig. 3, and shaft 2 on the slot 14 and surface 15 will swing all the windows outwardly and upwardly simultaneously, Fig. 5.  To close the windows the ram 5, Fig. 2, is connected so as to exhaust, preferably through a constriction, so that the weight of the windows will return them gently to the closed position.  If one or more of the windows have been opened manually and left open as in Fig. 4, then operating the ram to rotate the shaft will open any windows that are closed and will move the pegs 12 back along the slots 14 of any that are open thereby returning the centre of gravity to the original side of the pegs 12 as shown in Fig. 5.  A pneumatically operated ram may be used in place of the hydraulic ram.  Specification 546,979 is referred to.
Patent GB-193646-A (GB)
Title: Improvements in the dyeing of cellulose acetate
IPC: D06P3/44
Filed: 1922-02-04
Abstract: In a single-bath process of forming azo dyes upon cellulose acetate silk the amino compound and the second component are absorbed by the silk from a single hot bath and the nitrous acid or nitrite and acid is then added to the same hot bath; diazotization is thus effected at temperatures of 30-90 DEG  C. and the colour is rapidly developed. The amino compounds are dissolved in the bath by means of acids and the phenolic components by means of alkalis, and their absorption is facilitated by the addition of salts such as sodium acetate; protective colloids may also be added.  The dyeings may be shaded by addition of basic dyes to the bath, and the dyeings may be after-treated in acid solution with reducing-agents such as formaldehyde-hydrosulphite or stannous chloride to remove any loose colour.  According to examples: a red shade is obtained from aminoazobenzene and b -oxynaphthoic acid and may be topped by Butter Yellow or Nile Blue; a maroon shade is obtained from aminoazotoluene and b -oxynaphthoic acid in presence of Nile Blue; a navy-blue is obtained from dianisidine and b -oxynaphthoic acid; a black is obtained from 1-aminobenzene-4-azodimethylaniline and b -oxynaphthoic acid; in each of these examples diazotization is effected by means of sodium nitrite and formic acid. p-Nitraniline and naphthylamines are also specified as first components and phenol, resorcin, naphthols, dioxynaphthalenes, aminonaphthols, naphthylglycines, dimethylaniline, or 1-phenyl-3-methyl-5-pyrazolone, as second components.
