Title: Method of producing bulky textured hybrid yarn and yarn produced thereby
IPC: D02G1/18
Filed: 1975-08-29
Abstract: 1513927 Bulking yarn by fluid texturing and heat shrinking VYZKUMNY USTAV PLETARSKY 29 Aug 1975 [6 Sept 1974] 35666/75 Headings D1F and DIW A hybrid textured and bulked yarn is obtained by passing threads 3, 5 of different shrinkability through a turbulent fluid texturing nozzle 10 to produce crimps and loops and intermingle the threads, and heat shrinking at least the more shrinkable threads to produce in them a specific shrinking stress of at least 0.1 p/dtex so as to enlarge and set the crimps and loops by passing the textured yarn 12 through heater 13. Generally the threads 3, 5 are each multicontinuous filament yarns but in example 3 the less shrinkable threads are supplied as a roving of staple polyester fibres and in example 4 the more shrinkable threads are staple copolyester fibres. The specified more shrinkable thread is an ethylene terephthalate/isophthalate copolymer of 40% shrinkability. The threads of lower shrinkability are of polyester, nylon, rayon, acrylics or polypropylene. In example 1 polyester filaments of 10% shrinkability are fed to nozzle 10 with 20% overfeed and copolyester filaments of 40% shrinkability are fed with 10% overfeed. The textured yarn is shrunk by heating to 150‹C. In example 2 filaments of different shrinkability are obtained from the same polymer by drawing one freshly extruded filament over one heater whilst another filament is drawn over two heaters. The bending moment may be reduced at intervals along the filaments by flattening or otherwise changing the filament crosssection, so as to make the length and frequency of the loops more controllable.

Title: Improvements in or relating to time and temperature controlled switch mechanism
Inventor: BOWEN TOM
IPC: H05B1/02
Filed: 1959-10-22
Abstract: 971,622. Thermal switches; time switches. S. SMITH & SONS (ENGLAND) Ltd. Oct. 21, 1960 [Oct. 22, 1959], No. 35874/59. Heading H2B. In a time and temperature controlled switch having a manually-adjustable heat-responsive means, when a delay period has been set, the temperature adjustment is made against spring action, the temperature adjusting member being held in adjusted position by means of a detent which is released at the set time. As shown, rotation of temperature setting spindle 50 winds up a spring 56 via pinions 51, 52. The inner end of spring 56 is fixed to a shaft 53 and its outer end to a cup 57 loose on the shaft 53. The cup 57 has a notch 59 engageable by a pawl 67 on a lever 66 when " off " timing mechanism 4 (which may be that of Specification 971,621) has been set. Setting of mechanism 4 causes a spindle 15 to be lowered so as to tilt lever 66 clockwise about a pin 82. In addition, a second lever 65 is also tipped in the same direction to engage a pawl 71 with ratchet teeth 62 on a cup 58 secured to shaft 53. Rotation of cup 58 by spindle 50 causes lever 65 to oscillate about the lower end of spindle 15 since it has a slot 76 engaging the pin 82. A second timer mechanism 5 (similar to mechanism 4) allows a normally-closed switch 9 to close when the " on " time is reached to close the supply circuit, which is re-opened at the "off" time by upward movement of spindle 15. This permits counterclockwise movement of lever 65 by a spring 74 to disengage pawl 71 and teeth 62 so as to free the cup 58. The spring 56 thereupon unwinds and returns the thermostat to " off " position in which a second switch 8 is opened. When the time controlmechanisms are not set, the spring 56 is not strained by adjustment of spindle 50.
