Title: Treatment of textiles and compositions therefor
Inventor: PAYNE JOHN
IPC: D06M13/02
Filed: 1956-02-16
Abstract: Spun or unspun textile fibres are treated with colloidal dispersions of silica in a textile oil, preferably containing a dispersing agent favouring water-in-oil dispersions, to improve the interfibre friction.  Specified textile materials are wool and wool blends with nylon, rayon, polyester and protein fibres. Unspun fibres may be treated at any time prior to spinning.  The compositions may be applied by spraying.  Specified oils are mineral oils; vegetable oils (olein, arachis oil, castor oil, olive oil and other glycerides); sperm oil; and oil blends, e.g. sperm oil and castor oil or olein and mineral oil.  Dispersing agents specified are lanolin; mono-and di-esters of long-chain n-alkyl carboxylic acids (e.g. lauric, stearic, oleic or palmitic acids) with di- and polyethylene glycols; propylene glycol and glyceryl esters of long-chain alkyl carboxylic acids; sorbitan-fatty acid condensates (e.g. sorbitan sesquioleate); and ethylene oxide-fatty alcohol condensates.  Suitable silicas may have particle sizes from 10-100 millimicrons and may be prepared by combustion of silicon or tetraethyl orthosilicate or of gaseous silicon compounds such as silicon tetrachloride or silicochloroform in air or by removal of the organic solvent from a silica organosol to form an aerogel.  The sols may be obtained by stirring the silica into a solution of the dispersing agent in the oil, and may contain 5-10% of silica and 1,5-10% of the dispersing agent, by weight of the oil.  Examples are given. Specifications 607,696, 626,847 and 654,858 are referred to.ALSO:Colloidal dispersions of silica in a textile oil, preferably containing a dispersing agent favouring water-in-oil dispersions are used in the improvement of textiles and textile fibres; the dispersions are of improved stability and reduced viscosity.  The oils to be used are nonvolatile water-immiscible pourable liquids, specified oils being mineral oils; vegetable oils (olein, arachis oil, castor oil, olive oil and other glycerides); sperm oil; and oil blends e.g. sperm oil and castor oil or olein and mineral oil.

Title: Improvements in and apparatus for the manufacture and production of gaseous unsaturated hydrocarbons
IPC: C07C4/04
Filed: 1935-02-15
Abstract: <PICT:0451958/IV/1> Unsaturated hydrocarbons, e.g. olefines are obtained by subjecting gaseous or vaporous hydrocarbon to treatment at temperature of 650--900 DEG  C. in a Cowper stove or like chamber in which the free cross-section available for the passage of the gases is not more than one tenth of the total cross-section of the reaction chamber, the gases after the treatment being discharged rapidly without passage through the combustion chamber used to heat the stove.  The gases are preferably led at a speed of 40 metres per sec. or more through narrow passages formed by subdividing the eccentric space into channels of less than 1 cm. cross-section.  A Cowper stove A is provided with refractory bricks G of silicon carbide so as to form channels L 2.5 mm. wide; the free cross-section of the stove being 137,5 sq. cms. and the total cross-section 3735,5 sq. cms.  The stove is heated to 1000 DEG  by flowing hot gases from a combustion chamber B through the channels L, part of the gas being recycled by a blower H.  Gases to be treated are then led in through K and pass off through a spray cooler N.  Steam can be introduced for scavenging through J. A gas mixture containing 3 per cent H2, 5 per cent CH4, 18,8 per cent C2H6, 0,2 per cent C2\H4, 48 per cent C3H8, 2 per cent C3H6, 19 per cent C4H10, 1 per cent C4H8 and the remainder nitrogen is thus converted into a product containing 18 per cent H2, 37 per cent CH4, 25 per cent C2H4, 6 per cent C3H6, 1,5 per cent C4H8 and 11,5 per cent of homologues of methane.

Patent GB-910914-A (GB)
Title: Pour point apparatus and process for using same
IPC: G01N25/04
Filed: 1961-02-10
Abstract: 910,914. Determining pour points. ESSO RESEARCH & ENGINEERING CO. Feb. 10, 1961 [March 8, 1960], No. 5022/61. Class 97 (3). [Also in Group XL (b)] An arrangement for determining the pour point of oils, i.e. the minimum temperature at which the oil is mobile, comprises a container for the oil and rotatably mounted near its top on a rigid and stationary horizontal pivot axis so as to be capable of rotating in a vertical plane, a light source positioned to permit a beam to strike the surface of the oil within the container, a photo-electric sensing element positioned to change its electrical signal output upon angular movement of the oil surface with respect to the container, whilst the oil is mobile, a temperature sensing means immersed in the oil within the container, and means for periodically and partially swinging the container about the horizontal pivot. The arrangement includes means for gradually reducing the temperature of the oil to a value at which it is no longer mobile, so that during the rocking motion there is no change in the electrical signal from the photoelectric sensing element. As shown in Fig. 1, the oil 5 is in a container 2 mounted in a casing pivoted at 4, and carrying an arm 12 engaged between a biasing spring 16 and an eccentric cam 15 rotated at one revolution per minute. The container has a closure member 3 carrying a thermocouple member 7 and formed with channels for a light source 8 and a photo-cell 11. Normally, i.e with the container in the position shown, no light from the source 8 reaches the photo-cell 11, but with the oil in liquid form, the rocking of the container changes the relative position of the surface 6 so that some light is reflected to the cell, until with the oil temperature sufficiently reduced, the oil surface remains invariable with respect to the container and no light reaches the cell. In the circuit arrangement, Fig. 3, with contacts 18, 19 closed, a capacitor 22 is charged and provides anode voltage for a thyratron 23. If the cell 11 receives light reflected from the oil surface, a valve 28, operating as a cathode follower, controls a valve 29 to apply positive voltage to render the thyratron 23 conducting to effect discharge of the capacitor 22. If no light reaches the cell 11, the thyratron remains non-conducting, and the closure of contacts 18, 20 effects discharge of the capacitor 22 through relay 30 which operates, locks up over actuated contacts 31 and 32 and over contacts 34, 35 actuates a control circuit 36 to hold a recorder 37 at its last reading which is the pour point of the oil sample. Other dispositions of the light source in relation to the oil surface and the photo-cell are described in connection with the diagrammatic arrangements of Fig. 2 (A, B, D, E, F, G) (not shown), the arrangement of Fig. 2C (not shown) being regarded as similar to the embodiment of Fig. 1. Two of the diagrammatic arrangements, Fig. 2 (F, G), may be used to detect the cloud point in addition to the pour point for the sample of oil in the container.

Filed: 1950-02-28
Abstract: 667,991. Compressors. MANSTED, S. A. J. Feb. 28, 1950, No. 5097/50. Class 8 (i) In a compressor having opposed pistons working in a cylinder block which rotates around an axis at right angles to the cylinder axis, the pistons work pairwise in a common through going cylinder bore, and are driven in counter-phase by stationary, oppositely directed eccentrics which are mounted at the axis of rotation and a channel from the cylinder bore opens out on one side surface of the cylinder block and co-operates with an annular slide valve face at right angles to the axis of rotation. A cylinder block 4 formed in one with a driving shaft 3 is provided with a bore containing pistons 18, 19 the outer ends of which are connected by rods 20, 21 to eccentrics 15, 16. A bore 31, Fig. 2, in the cylinder face co-operates with a slide valve face having an inlet chamber 9 and an outlet chamber 10. An extension shaft 6 drives a lubricating pump 17. A bore 25, Fig. 2, is closed by a valve 24 secured to one side of a frame 26, two other sides being guided in bores in the cylinder block and passing freely through slots, in the pistons 18, 19 ; to the fourth side is secured a mass 28. Balancing masses 29 are secured to the cylinder block 4.. Springs 27 normally hold the valve 24 open until centrifugal force acting on the mass 28 overcomes the force of the springs and the valve closes.

Title: Improvements in and relating to control systems for regenerative braking of electricmotors
IPC: H02P7/34
Filed: 1936-02-20
Abstract: 470,771. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., LIDDIARD, H. W. C., and PETCH, T. H. Feb. 20, 1936, No. 5154. [Class 38 (iii)] Regenerative braking.-Regenerative braking is effected in a Ward-Leonard system by providing separate exciters 2, 4, for the motor and generator fields 1, 3, and a switch 17, 18 is arranged to disconnect the field 9 of the generator exciter 4 to allow it to decay under control, the field 7 of the motor exciter 2 also being disconnected by a switch 19, 20, dependent on the operation of the first switch 17, 18, so that the field 7 of the motor exciter 2 also decays under control, and a desired relationship in the decay of the two fields is maintained. Upon opening of a switch 15, a relay coil 16 is de-energized and contacts 17, 18 opened, so that the field 9 of an exciter 4, supplying the generator field 3 is disconnected and the field 9 discharges through a resistance or condenser or through the armature of a motor 12 driving a flywheel 13. The rate at which the field 9 dies away is determined by the size of the flywheel, and may be adjusted. by means of a friction brake on the flywheel, an oil damper or rotating air vanes. An adjustable resistance 11 may also be provided in parallel to the field 9. As the field 9 dies away the motor supplied from the generator is regeneratively braked. The de-energization of the relay coil 16 also opens contacts 19, 20, to disconnect the exciter field 7, and this field allowed to discharge in the same way as the field 9 discharges. The discharge circuit for the field 7 may comprise the armature of a motor 21 driving a flywheel 22, and an adjustable resistance 24 may be connected across the field 7. The flywheel 22 will be large in relation to the flywheel 13. A brake coil 25 may be connected across the exciters 4 or 2, or the brake coil may be de-energized by a relay, so that the main brakes are tripped at a predetermined voltage across the fields 1 or 3. The Provisional Specification refers to a system in which the motor field is maintained at full strength by maintaining the field of the motor exciter, or is disconnected by a relay operating a fixed time after braking is initiated, or in response to falling voltages resulting from the de-energization of the field of the generator exciter. Specification 434,668 is referred to.

Title: Improvements relating to model railway trains
IPC: A63H19/18
Filed: 1933-02-22
Abstract: 415,410. Toy-train coupling devices. OULD, J. V., 13A, South Parade, Southsea, Hampshire. Feb. 22, 1933, No. 5462. [Class 132 (iii).] A coupling for a model or toy railway train comprises a loop member pivotable about a horizontal axis, a hook to engage the loop to effect coupling, and an electromagnet, to which current is supplied through a running rail and an additional rail, for moving the loop to effect uncoupling. The coupling device comprises a hook 16 with inclined edge 20 and a wire loop 10 fixed to an armature 22 rotatable about the pivot pin 14 carried by lugs 52 bent up from the member 50 secured at 51 to the floor of a coach and carrying the electromagnet 24 earthed by a wire 26 to the coach and connected by a wire 29 to a spring pressed shoe 30 engaging an additional rail 34 and insulated from the frame of the coach. A running rail and the additional rail 34 are connected to a battery 36 by means of wires 38, 40 through a press-button 42. Two shoes 30 connected by a wire 44 may be provided and the additional rail 34 may extend the whole length of the track or may be in the form of a short ramp so that uncoupling can only occur thereat, the pressbutton 42 being optional in the latter case. An indicating lamp may be connected across the contacts of the press-button 42, the resistance of the lamp preventing the lifting of the armature 22 when the press-button is open. The lamp lights up when the shoe 30 is on the additional rail or ramp but goes out when the pressbutton is closed. When the locomotive is driven by an electric motor the circuit of which is maintained through a live rail placed between the running rails and the running rails, the electromagnet 24 is supplied from the same battery as the motor, the two circuits being in parallel. When a reversing switch is used for the motor this may be so connected as to control both circuits. If a resistance is employed for speed regulation this is connected so that it cannot come in series with the electromagnet.

Title: Fabric draw-off mechanism for a flat knitting machine
IPC: D04B15/90
Filed: 1959-02-17
Abstract: 863,763. Knitting-machines. STOLL, R., STOLL, E., STOLL, H., STOLL, G., and STOLL, E., [trading as STOLL & CO., H.]. Feb. 17, 1959 [Feb. 28, 1958], No. 5468/59. Class 74(2). The fabric draw-off mechanism for a flat machine comprises a draw-off roller 51 which is intermittently rotated by the action of a weighted pivoted arm 46 through pawl-andratchet mechanism 49, 50. The arm 46 is raised every time a follower 53 or an arm 48 attached to arm 46 is engaged by a constantly revolving cam 52 so as to reposition the pawl 49 in relation to the ratchet. To maintain the fabric draw-off tension constant the weight 45 on the arm 46 is movable therealong by a chain 44 secured to it and driven from a sprocket 43. The sprocket 43 is rotated in one direction or the other to move the weight inwardly or outwardly along the arm by either one or the other of two continuously reciprocating pawls 26, 28 which are adapted to be rendered operative or inoperative through the action of two solenoids 14, 15. These solenoids are energized according to the tension imposed on the fabric proceeding from the needles of the machine and at the dictates of feeler rollers 2 which are supported to lightly impinge on the fabric so that as the rollers move and pivot, according to whether the fabric is taut or slack, a bell crank lever 1 supporting them causes a link 5 connecting the lever 1 to an arm 9 to raise or lower the arm 9 to close electrical switch 12 or 11 coupled to the appropriate solenoid. The rollers 2 are balanced by a weight 7 supported on the end of link 5 and in the event of an increased tension in the fabric being required an additional weight 20 may be attached to the link, and such increased loading may be under the control of pattern mechanism on the machine.
