Abstract: 987,863. Thermal switches; cam operated switches. S. SMITH & SONS (ENGLAND Ltd. July 14, 1961 [July 14, 1960], No. 24508/60. Heading H2B. The switch comprises an actuator arranged to be moved by a spring between a variable displaced position and a datum position, means holding the actuator in its displaced position, a trip member settable in the path of a part movable by a thermal element so as to be engaged by said part at a temperature dependent on the setting, the actuator being connected to the trip member by a cam and follower so that the setting of the trip member is dependent on the displacement of the actuator, the latter being released by engagement of the trip member by the said part. As shown, the actuator comprises a shaft 7 carrying a cam 37 controlling a switch 65 and is movable clockwise from the datum position shown in Fig. 2 to stress the spring 23. A cam 6 on shaft 7 tilts a lever 17 about an adjustable pivot 19 to an extent determined by the rotation of the shaft 7, which is held in its displaced position by the end 16 of lever 17 engaging a tooth 14 on the cam 6. When the predetermined temperature is reached a part 33 carried by a diaphragm 34 engages a part 30 carried by lever 17 and tilts the end 16 clear of cam 6 so that the shaft 7 is restored by the spring 23 to the datum position. The camshaft 7 is set by a spindle 10 via helical gears 8, 9, and if after setting cam 6 it is desired to set a lower temperature the spindle is turned in the appropriate direction. Since cam 6 is locked by end 16, the reaction of gears 8, 9 causes the spindle to be displaced to the right, Fig. 2, so that a disc 12 engages a lever 13 which has lugs 73 which tilt lever 17 to disengage end 16 from the cam. In the datum position of shaft 7, a lug 24 displaces an arm 27 pivoted at 28 so as to disengage a brake 55 from the balance wheel 43 of a timer, Fig. 3. A time delay is set by turning a shaft 40 carrying switching cams 51... 53 counterclockwise to strain a spring 41 an amount depending on the desired delay, the delay period only starting when the brake is moved clear of wheel 43.

Patent GB-648854-A (GB)
Title: Improvements in or relating to the straightening of animal fibres, particularly in the form of furs and pile fabrics
IPC: D06M15/39
Filed: 1947-09-05
Abstract: Animal fibres, particularly when they form the pile of a pile fabric, are impregnated with a thermo-hardening or thermo-setting synthetic resin or a partially condensed or partially polymerized synthetic resin or with reagents which react together to form such resin, and are subjected to a vigorous brushing treatment at elevated temperature during which treatment they are straightened and in which forming, hardening, or curing of the resin takes place.  The mechanical straightening operation may be effected at 100-160 DEG  C. It may be a brushing treatment with rapidly rotating brushes. Additionally, the fibres may be brought into contact with heated rollers.  Frictional heat evolved by the brushing operation promotes the formation of the synthetic resin and its hardening.  The synthetic resin may be phenol-formaldehyde, an amine- or amide-formaldehyde such as urea-formaldehyde, a ketone-formaldehyde, casein-formaldehyde, a polyhydroxy alcohol/polybasic acid resin, a polyvinyl ester or acetal, polystyrene, or a polyacrylic resin.  More than one resin may be used.  The fibres may be subjected to a pre-treatment with a softening agent, e.g. steam, dilute alkali, or dilute acid, e.g. acetic acid.  The base fabric may be rendered non-receptive of the applied resinous material or resin components. Prior to the vigorous brushing treatment, the fibres containing the resinous material may be passed over or held stationary against a rapidly revolving heated roller at 120-160 DEG  C.  They may be passed over stationary brushes or may be brushed by rotating brushes. Brushing may be interspersed with combing or carding.  The direction of brushing may be varied during the treatment.  Curing of the resin may be completed by a further heat treatment.  In an example, a wool-pile fabric having a cotton base is steamed to soften the wool. The pile is brushed until nearly dry and a liquid phenol-formaldehyde product is applied.  The fabric is vigorously brushed until the desired degree of straightening has been achieved and the fibres are no longer tacky.  A solution of urea-formaldehyde in alcohol is applied and brushing continued until all tackiness has gone.  The fabric is heated to 120-130 DEG  C. to complete the curing of the resins.  After washing, the pile fibres are soft and glossy as well as in alignment. Specifications 497,647 and 609,625, [Group VIII], are referred to.
