Filed: 1976-06-29
Abstract: 1508921 Sulphur fluorides ALLIED CHEMICAL CORP 29 June 1976 [2 July 1975] 27093/76 Heading C1A A sulphur fluoride selected from sulphur tetrafluoride, sulphur chloride pentafluoride, sulphur hexafluoride and mixtures thereof is made by reacting under anhydrous conditions, sulphur chloride with nitrosyl fluoride or nitrosyl fluoridehydrogen fluoride complex at a temperature above the melting point of the highest melting of said compounds in said reactant mixture, whereby a mixture of said sulphur fluoride and nitrosyl chloride is formed. The sulphur chloride may be made in the presence of the fluorine-containing compound by reacting sulphur with chlorine at a temperature above about - 10C and sulphur tetrafluoride product may be reacted with chlorine and nitrosyl fluoride to form a reaction mixture including sulphur chloride pentafluoride and nitrosyl chloride. The latter may be reacted with hydrogen fluoride to form nitrosyl fluoride-hydrogen fluoride complex. Where nitrosyl fluoride is used excess chlorine may be added to the reactant mixture to form as the predominant sulphur fluoride, sulphur chloride pentafluoride which may be heated to between 350 and 475C to form a reaction product containing sulphur tetrafluoride, sulphur hexafluoride and chlorine, and the resulting by-product nitrosyl chloride may be reacted with hydrogen fluoride to form nitrosyl fluoridehydrogen fluoride complex which is decomposed to regenerate nitrosyl fluoride which is recycled to the reactant mixture. In a continuous process, sulphur tetrafluoride is made by combining nitrosyl fluoride-hydrogen fluoride complex, chlorine and sulphur as ingredients in a reaction mixture; continuously reacting said ingredients together by causing the reaction mixture to reach a temperature above about 5C; continuously fractionating the reaction mixture to remove hydrogen chloride and then to remove sulphur tetrafluoride; and continuously adding sulphur, chlorine and hydrogen fluoride to the mixture to maintain a numerical ratio of sulphur atoms, to chlorine atoms, to nitrosyl fluoride molecules, to hydrogen fluoride molecules of greater than 1:4:4:>12.

Filed: 1960-08-04
Abstract: 955,475. Valves. A. M. MOEN. Aug. 4, 1960 [Feb. 3, 1960], No. 27097/60. Heading F2V. A valve for controlling the flow of liquids comprises a housing 1, Figs. 1 and 2, with inlet openings 3, 4 and an outlet opening 5 and a removable valve cartridge positioned within the housing, the cartridge having a sleeve 11 with inlet and outlet passages passing through it to co-operate with passages 27, 28 leading to and from the interior 26 of a hollow valve stem which may rotate and reciprocate within the sleeve. The sleeve is secured, to the housing 1 by a key 10 and contains a lock ring 34 to cooperate with snap rings 32 on the valve stem to limit axial movement. O-rings are provided between the stem and the sleeve, a vent 21 permitting escape of air, and between the sleeve and the housing, one 0-ring, 17, being inclined to separate the ports 3, 4 which may supply hot and cold water to an inlet port 27 in the stem after the latter has been upwardly displaced from the position shown. From the interior of the stem the water flows through ports 28 annular recesses 19, 29 and ports 30 to the outlet port 5. Angular movement of the stem varies the extent to which the port 27 is in register with the ports 3 and 4 and hence the temperature at the outlet. The ring 17 may be replaced by a pair of horizontal rings connected by vertical sealing strips to separate the ports 3, 4 while the interior of the valve stem may contain a tube to permit fluid to escape from the lower part of the housing 1 to the annular space between the stem and the top of the sleeve. In a further modification the inlet and outlet ports in the valve stem are formed by a circumferential series of rectangular apertures and a single circular opening respectively while the sleeve is made of metal or plastic of thin sections and has its inlet ports 3, 4 sealed by rubber or rubberlike circular packings to which it may be bonded. The sleeve may also be perforated to permit penetration by one of the seals with the housing. A handle 193, Fig. 15, is connected by a screw 194 to a tapped hole 25 in the valve stem and is fitted with a plate 195 held in place by spring fingers 195a. A pointer 196 on the handle cooperates with an escutcheon 191 engaged by a bead on a stop tube 190 surrounding the valve housing. A diverter valve 176 may be opened to supply a bath tap 171 instead of a shower head 185.

Abstract: 412,598. Variable-speed driving arrangements for yarn-winding machines. HOLT, R., Atlas Iron Works, Whitworth Road, Rochdale, Lancashire. Oct. 1, 1932, Nos. 27280/32 and 30319/33. [Class 120 (ii).] In a machine for winding yarns or threads on to bobbins revolving at speeds determined by the speed of delivery of the yarn and the diameter of winding according to the movements of yarn guides, there is provided a three phase or other alternating current electromotor S and three, four or more electric resistances q connected with the slip rings r of the rotor windings of the motor and with a set of contact parts o, and contact means m for completing the circuit through the rotor windings and resistances to start the motor at one speed, the resistances also being connected to a set of contact parts p to receive contact of other contact means m<1> to short circuit the part of the resistances between A2, B2, C2, and A3, B3, C3 and drive the motor at a higher speed, the contact means m,m<1> connected by the bar m<2> being housed in a casing n and mounted on the same shaft g controlled by a treadle a so that depression of the treadle causes the contacts to be made one after the other, there being a series of contacts to be made if desired to progressively short circuit more and more of the resistances. The treadle a is connected by a link c with a bell crank lever d connected with a chain e secured to a block f on the shaft g carrying another block to which is secured a chain i secured by a spring j to the shaft l on which the treadle a and controlling weight b are supported. The shaft g carries in the housing n the contact parts m m<1>, the parts m being larger than the parts m<1> so that as the shaft g is rotated by depression of the treadle a the parts m contact with the contacts o before the parts m<1> contact with the contact p. Similarly when the treadle a is allowed to rise the contact p m<1> is broken before the contact o, m. In a modified form of the treadle mechanism the bell crank lever d is connected with a slotted bar, the slot permitting lateral movement of a stud carried by an arm on the shaft g which also carries a notched plate, the notches receiving a roller carried on a pivoted spring controlled lever. The engagement of the roller in the notched plate as the shaft g is rotated give greater certainty as to the positions in which the treadle should be held for the various contacts to be made. In a further modification the contacts as they are made energize electromagnets, on the armatures of which the contact pieces corresponding to m, m<1> are mounted. A multi-pole switch 24 may be provided to short circuit the parts of the resistances q between A1, B1, C2 and A2, B2, C2 if desired.

Abstract: 1360089 Battery charging systems J A MACHARG 1 Nov 1972 [16 Nov 1971; 12 June 1972] 53141/71 and 27355/72 Heading H2H The battery charging apparatus disclosed in Specification 1,309,394 is modified so that the ON periods of the ON/OFF cycle of the charging process are substantially fixed in length irrespective of the duration of the intervening OFF periods. This is effected by a timing means comprising a capacitor which is charged when an output appears from a device which compares the battery terminal voltage with a reference voltage, the capacitor subsequently discharging after the output of the comparator device has disappeared. The length of the ON periods may be made adjustable if desired. The control of the charging current is effected by way of a thyristor bridge, the gate signals for the thyristors being derived from a dynamic load device whereby the lower part of the conduction characteristics of the thyristors are made substantially linear. Parts of the circuitry used in the invention are similar to those disclosed in Specification 1,225,802.

Title: Improvements in or relating to the production of artificial filaments
IPC: D01F2/30
Filed: 1928-09-28
Abstract: 326,461. British Celanese, Ltd., and Taylor, W. I. Sept. 28, 1928. Apparatus for making filaments.-For the production of artificial filaments of large crosssection, a number of artificial filaments extruded from a plurality of spinning orifices are by means of a fluid stream caused to converge together and to unite while they are setting and are therefore in a sticky or tacky condition. The method is particularly applicable to the dry spinning process using solutions of cellulose acetate or other esters or ethers of cellulose; but it may also be applied to the wet spinning of solutions such as nitrocellulose, viscose, or cuprammonium cellulose. It is convenient to maintain around the filaments, prior to their convergence and adhesion, a medium rich in solvent. For effecting the desired convergence of the filaments, the latter mav be passed through a double cone device 4, Fig. 1, mounted in the cell at a short distance below the spinning nozzle 2; air is blown through the space between the inner and outer cones 5, 6, the outer cone preferably extending beyond the inner. As an alternative a sleeve or hood 15, Fig. 2, may be adjustably mounted on the candle 16, the lower portion of the hood being closed by a hinged plate 18 in order to maintain within the hood an atmosphere rich in solvent vapour; the plate is slotted to permit the passage of the filaments, and in the centre of the plate there is provided an incomplete ring 21 having a number of perforations or slots 22 or a single slot through which inwardly-directed jets of air are projected on the filaments. The united filaments may be withdrawn through an opening 10, Fig. 1, in the side of the cell, passed round a feed roller 11 which may be run at a speed sufficient to stretch the filaments and finally wound on a roller 12. The filaments obtained may be used to produce figured, pattern or other effects in woven or knitted materials, and they may be used in conjunction with other artificial threads of the same or different types or with natural filaments or fibres; they may be doubled or twisted with other yarns. Specification 322,557 is referred to.
