Title: Improvements in or relating to spinning processes and apparatus therefor
IPC: D01D5/04
Filed: 1947-05-01
Abstract: <PICT:0639723/IV (a)/1> <PICT:0639723/IV (a)/2> Gaseous medium is supplied to spinning cells into which artificial filaments are spun by passing a stream of gaseous medium through a main supply duct in large excess of the amount required by the cells, then passing the stream directly from the supply duct into or through a contiguous return duct, withdrawing the requirements for the cells from the stream at spaced points along one of the ducts, and maintaining the stream in the return duct in heat interchange relationship with the stream in the main supply duct by means of a closed heat-conductive partition therebetween along all of that portion of their length comprising the spaced points of withdrawal.  The process is applicable to dry-spinning in which case a heated evaporative atmosphere is supplied, and to melt-spinning, in which case a cooling medium is used.  As shown, a fan or blower 3 is connected to a main or feeding duct 2 which is provided with side ducts 4 communicating directly with the spinning cells 5.  A return duct 6 surrounds the main duct and receives excess medium discharged from the open end 7 of duct 2, and is provided with a layer of insulating material 8.  If desired, the fan, ducts thereto, spinning cells and any unprotected parts of the branch outlets may also be insulated and the spinning cells may also be provided with a jacket 81 for heating or cooling. A pipe 9 connects the return duct to the blower, and may be provided with heating or cooling means (steam coil, electric heater or brine coil) as required.  An open branch pipe 11 provided with a filter 12 and a damper 13 controls the admission of supplementary air from the spinning room or of gas or vapour from the supply vessel.  The damper is adjusted so that from 2-10 times the amount of air actually used is introduced into the duct 2.  Alternative arrangements described include (a) the branch ducts communicating direct with the outer return duct instead of the inner main duct, (b) the blower discharging into an outer main duct, the side branches opening into an inner return duct, and (c) as in (b) with the side branches opening into the outer main duct.  If desired, the blower may communicate with opposite ends of two parallel ducts with one set of spinning cells between them, each cell communicating with both ducts, the return ducts discharging into opposite sides of the blower.  A plurality of machines or of rows of spinning cells may be supplied by one fan.

Title: New steroid compounds
Inventor: OUGHTON JOHN FRANCIS
IPC: C07J75/00
Filed: 1954-04-28
Abstract: The invention comprises cyclpseudo-sapogenins which are isomers of iso-(22a)-sapogenins and have the following infra-red absorbtion characteristics: g  max. circa 1070, 1012, 920, 895, 856 and 785 cm.-1, no absorbtion at circa 98 DEG  cm.-1, said compounds being convertible to pseudo-sapogenin acetates by heating with acetic anhydride at temperatures from 100 DEG  to 150 DEG  C., and the preparation thereof by subjecting a pseudo-sapogenin derived from an iso-(22a)-sapogenin to the action of hydrogen to ions in the presence of an inert solvent under relatively mild conditions, i.e. conditions which are sufficient to bring about the desired isomerization but not so vigorous as to lead to the iso-(22a)-sapogenin.  The isomerization may be carried out with a strong mineral acid, e.g. hydrochloric, sulphuric or phosphoric acid, or with an organic acid, e.g. acetic acid.  The mineral acids are preferably used in a concentration between 0.02 and 2 per cent.  Suitable inert solvents are methyl and ethyl acetate, ethanol and chloroform.  Reaction temperatures may vary between 0 DEG  and 50 DEG  C., and in the case of hydrochloric acid, the preferred reaction temperature is 20-25 DEG  C.  The 3-esters of the above cyclopseudo-sapogenins containing a 3-hydroxy group may be prepared, e.g. by reaction with an acid anhydride and pyridine. The above cyclopseudo-sapogenins may be converted into pseudo-sapogenin esters by heating with a carboxylic acid anhydride, either alone or in an inert liquid medium, suitable anhydrides being aliphatic carboxylic anhydrides, e.g. acetic, propionic, butyric, valeric, caproic and capryllic anhydrides. The above cyclopseudo-sapogenins may also be converted into iso-sapogenins by the action of heat in the presence of a strong mineral acid, e.g. hydrochloric acid, preferably at a temperature between 70 DEG  and 120 DEG  C.  In the examples the following compounds are prepared: 11-oxo-cyclopseudo-tigogenin and the 3-acetate thereof, cyclopseudo-hecogenin and the 3-acetate thereof, cyclopseudo-tigogenin, cyclopseudo-diosgenin and the 3-acetate thereof, and cyclopseudo-smilagenin and the 3-acetate thereof. The examples also exemplify the preparation of 11-oxo-psuedotigogenin diacetate from 11 - oxo - cyclopseudo - tigogenin, pseudohecogenin diacetate from cyclopseudo-hecogenin, pseudotigogenin diacetate from cyclopseudo-tigogenin, hecogenin from cyclopseudo-hecogenin, and 11-oxotigogenin from 11-oxo-cyclopseudo-tigogenin.

Abstract: 1,177,032. Indicating apparatus. HUSQVARNA VAPENFABRIKS A. B. March 14, 1968, No. 12339/68. Heading G1J. In order to make manual compensating adjustments to the setting of a room thermostat which has an element directly affected by one or more room heaters as well as by the temperature inside the room, at least two concentric scale knobs 3, 6 are provided, fixed and relatively rotatable respectively to the thermostat spindle 2 and each having a temperature scale and index mark 11, 12 and 9, 10, the scale on knob 3 being calibrated empirically so that by setting it to indicate the external environmental temperature, a rotation of the spindle 2 is superimposed on its setting by the knob 6 to a desired internal room temperature to compensate for the direct effect on the sensing element of the room heaters in so far as that effect is dependent on the external temperature. As shown, the scale 11 and index mark 12 are applied to the knob 3 and a third knob 5 and the scale 9 and index mark 10 are applied to the knob 6 and a cover 1. A frictional coupling between the three knobs is produced by springs 7, 8 (between knobs 5 and 6 and between knob 6 and a disc on the spindle 2) maintaining engagement between conical surfaces and readily released by depressing the knob 6 or knobs 5, 6 lowest on the spindle 2.

Class 118(2) A direction indicator for a vehicle of the kind comprising an illuminated arm formed of two translucent members 13 separated by an opaque partition 14 which prevents wholly the transmission of external light from one side of the arm to the other, is pivoted by bolts 32 in a bracket 12 attached to the vehicle body and is retained in a position at rightangles to the body by spring-loaded cam followers 35 engaging notches in cams 34. The cams are so shaped that the arm can swing back on striking an obstacle, and then return automatically to its central position unless it is deflected so far that the followers engage notches at the end of the cam profiles and hold the arm parallel to the. side of the vehicle. Each member .13 is rendered opaque by paint to define an arrow 16 and lamps 25 are provided on both sides of partition 14. The lamps are carried on an circulating plate 21 formed with grooves 22 which slide into a slot 19 cut in the partition. Connections to clips 24 holding the lamps are made by strips 23 which extend to the inner end of plate 31 where they are engaged by clips 45 on a detachable plug 39 having 'leads 42 extending through a flexible covering 43. The inner faces of member 13 are serrated to provide facets over the areas of arrows 16. In a second embodiment, Fig. 5 (not shown), the cams are mounted on the bracket and the followers are carried by the arm. The electric connections to the plate carrying the lamps are effected in this case by spring-loaded plungers located within pins about which the arm pivots in the bracket. In a third embodiment, Fig. 6 (riot shown), only a single cam and follower system is employed. The slot in the partition extends to the outer end of the arm so that the plate carrying the lamps may be withdrawn from the outer end.

Title: Carbonisable fibrous sheet
IPC: D04H3/002
Filed: 1972-07-21
Abstract: 1447030 Needled fibre fabrics HYFIL Ltd and COTTON SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION 18 July 1973 [21 July 1972] 12416/76 Divided out of 1447029 Heading D1R Onto a unidirectional warp array 10 of continuous carbonisable filaments in an oxidised state are cross laid other of said filaments on one side of the array in a state of restraint from displacement from their cross-laid relationship, and the resultant assembly is needle punched from the resultant assembly the same side. The fabric produced may be carbonised. In one embodiment the state of restraint is produced by previously passing the warp array 10 through needling machine 14 and winding it up on roll 30, the needling being from the second side of the warp so as to push loops and broken ends of filaments out from said one side, the upper side in Fig. 2, to key weft array 34 which is cut and cross laid whilst warp 10 is stationary. An additional warp and an additional weft array may be needled onto the fabric (Fig. 3, not shown). The two weft arrays may be at 45‹ to the warp and at 90‹ to each other. The exemplified array is a 24 inch wide sheet of 25,000 continuous 1.5 denier polyacrylonitrile filaments per inch, the filament array having been divided into groups to enable at least one weft filament to be woven over and under said groups to hold the sheet together. The weft filaments may alternatively or additionally be restrained by resilient pads 38 on stripper plate 22 of the needling machine. The weft filaments are 2 inches longer than the width of the warp array so that pads 38 exert pressure on the fringes of weft array 34. Stripper plate 22 pivots to allow the fabric to pass freely through the needling machine during the advance stage of the cycle. After carbonising the fabric may be "pre sized" with a resin solution, dried and impregnated with a matrix solution, as claimed in Specification 1447029.

Title: Improved method of reducing ores with gases
IPC: C21B13/00
Filed: 1930-04-23
Abstract: In a cyclic process for the gaseous reduction of iron and other ores, of the kind described in Specification 130,334, [Class 72, Iron &c.], the charge is contained in a series of vertical receptacles arranged in pairs, and the gases pass downwards and upwards respectively through the charge in the receptacles of each pair.  The reducing gas from a producer 21 passes downwards through receptacle 1 and upwards through receptacle 2, and so on through each successive pair.  On reaching receptacle 7 the gas current is divided, part returning to the producer for regeneration and the remainder continuing to traverse the <PICT:0352580/III/1> receptacles; air is supplied at the top of receptacle 9, and the combustion products serve to preheat the ore in receptacles 10, 12 and then escape through conduit 25.  On completion of reduction in the leading pair of receptacles, the latter are detached from the train which is then moved forwards to accommodate a fresh pair at the rear.  The receptacles may be arranged in straight line, zig-zag, or annular formation.  The Specification as open to inspection under Sect. 91 (3) (a) states also that the process may be applied generally to the treatment of solids with gases, and mentions the burning of limestone, the purification of gases, and the carrying out of catalytic gas reactions.  This subject-matter does not appear in the Specification as accepted.
