Title: Improvements in or relating to False Twist Devices
IPC: D02G1/06
Filed: 1968-09-12
Abstract: 1,191,029. Driving false twist spindles. HEBERLEIN & CO. A.G. 12 Sept., 1968 [13 Sept., 1967], No. 43514/68. Heading D1D. [Also in Division F2] A reversing apparatus for a false twist spindle 34 comprises a frame member 16 movably attached to a fixed part 10 and carrying the false twist device 14, a driving shaft 20 to rotate spindle' 34, and arranged to engage driving means such as a belt 42, means to disengage the driving means to stop drive to shaft 20 and means to move the shaft 20 relative to the driving means, e.g. by moving shaft 20 to the opposite side of belt 42, to reverse the direction of drive to Spindle 34. As shown the false twist apparatus 14 is mounted on the member 16 which is mounted on a shaft 44 rotatable and longitudinal slidable in bearings in the fixed part 10. To reverse the direction of drive from that shown, a shaft' 76 is rotated by a handle to cause a cam 84 thereon to shift shaft 44 longitudinally and thus move pulley 22 on shaft 20 out of contact with the continuously driven 'belt 42. After depressing a locating catch, frame 14 together with the false twisting apparatus 26 can be rotated about shaft 44 out of the plane of the paper, moved to the left as shown in Fig. 7 and rotated back to its original orientation. Pulley 22 is now located on the opposite side of belt 42 and the cam follower 86 on shaft 44 is located on the opposite side of cam 84. Thus by rotation of shaft 76 pulley 22 can be brought into driven contact with belt 42 and the drive to spindle 34 is thus reversed.

Patent GB-1099799-A (GB)
Title: Improvements in the treatment of cellulosic fabric
IPC: D06M101/02
Filed: 1965-10-19
Abstract: A cellulosic fabric is sensitized by impregnating it with an aqueous solution of a curable textile creaseproofing material and then drying and partially curing the impregnated fabric to remove substantially all of the water originally present in the fabric and in the aqueous solution contained by the fabric to the extent that the crease resistance of the dried, partially cured fabric is 20-72% of the total gain in crease-resistance obtained when the fabric is substantially fully cured.  The total gain in crease resistance is the difference between the crease resistance of the fully cured fabric and that of the impregnated dried but uncured fabric.  Drying may be effected at 70-300 DEG F and partial curing at 200 DEG  - 340 DEG F for 1-5 minutes.  The crease-proofing material may be a condensation product of formaldehyde with melamine, urea, thiourea, cyanamide, dicyandiamide, cyclic ethylene urea, cyclic trimethylene urea, 4,5-dihydroxy cyclic ethylene urea, formamide, methyl or ethyl carbamate, triazones, acetoguanamide or urons or their alkylated or acylated derivatives.  The treating solution may also contain a catalyst, e.g. hydrochloric, sulphuric, phosphoric or maleic acid, ammonium chloride or phosphate, zinc nitrate, magnesium chloride, sodium phosphate and monoethanolamine hydrochloride, softeners, e.g. silicones and polyethylene dispersions, cationic surface active agents, stearoxymethyl triethyl ammonium chloride, polyvinyl alcohol, modified starch, polyvinyl acetate, acrylic resins, and oil and water repellents, e.g. silicones and fluorocarbon chemicals. Fabrics comprising cotton alone or in admixture with polyester, nylon or polyacrylonitrile fibres may be treated.  The fabrics may be stored and subsequently made up into garments, e.g. trousers, pressed into the desired shape and the curing completed, e.g. at 250 DEG -375 DEG F for 2-20 minutes.

Abstract: 1420921 Vehicle overload system  R M COOKE A J WHITNEY and S W SHERLOCK 14 Dec 1972 [28 Sept 1:971] 45153/71 Heading G1W A vehicle overload system comprises a load sensor for each axle or axle group, each load sensor being arranged to operate a signal lamp when the permissible load is reached and to  interrupt the vehicle starter motor circuit when the permissible load is exceeded. Each load sensor comprises a casing 1 mounted on the vehicle body, and a spindle 4 connected to the axle via rods 7, 10 and bracket 11, so that spindle 4 rotates as the vehicle body moves downwardly under load. Spindle 4 carries a cam 14 which operates switches 19, 20, 21 via cam followers, the angular position of cam 14 relative to spindle 4 being adjustable. Spindle 4 also carries a slider 13 co-operating with an electrical resistance track on an insulating plate 18. A display unit, Fig. 3, includes a pair of signal lamps and a meter for each load sensor. With no load on the sensor switches 19, 20, 21 are all open and no lamp is lit. When loading is started, switch 19 closes and a green signal lamp is lit. When the maximum permissible load is reached, switch 20 closes and a red signal lamp is also lit. Further loading causes switch 19 to open and switch 21 to close, switch 21 operating a relay to open a set of contacts in the starter motor circuit to prevent starting of the engine. The load at any instant is indicated on meter LM connected in series with the slider 13 and the resistance track. There may be a relay IC1 for each load sensor or a common relay for all the load sensors. Switch 21 may be replaced by a switching device operated from the signal provided by slider 13 and the resistance track. The on-off switch of the display unit may be shunted by the vehicle ignition switch to prevent the vehicle being driven when overloaded, merely by switching off the display unit. Alternatively, the relay may be arranged so as to have normally open contacts in the starter motor circuit, the relay being energized to close the contacts by switch 21 whenever the load is within safe limits.
