Patent GB-439341-A (GB)
Title: Improvements in the production of craped or crimped artificial yarns
IPC: D01F2/06
Filed: 1935-02-27
Abstract: Cr<\>zeped or crinkled artificial yarns are produced during the winding of the thread by rapidly alternating extensions and shortenings of the winding stretch, i.e. the distance between the moved winding-on device and the nearest thread guide member.  This effect is produced particularly simply in the centrifugal spinning process by disposing the thread guide funnel eccentrically in the spinning can, preferably closer to the axis of the can than to the can wall.  Thus with a can 150 mm. in diameter the funnel is advantageously 20 mm. from the axis of the can.  To obtain a more uniform crinkling, the funnel is moved during the winding process nearer to the axial line of the can, e.g. at a rate proportional to the growth of thickness of the winding.  Thus, the distance of 20 mm. from the axis of the can may be reduced to 15 mm. during the course of a winding.  The absolute diameter of the can is also found to affect the nature of the crimping, the crimps being larger and less numerous the greater the diameter of the can.  The composition and ripening of the viscose spinning solution and the composition of the coagulating bath are preferably adjusted to ensure that the threads are fed to the can in as plastic a state as possible.  The crimped thread may be treated in an acid fixing bath, containing, e.g. 5,7 per cent H2SO4 before further after-treatment.  After washing, the thread preferably has an intermediate drying treatment before further after-treatment.  When using spool, cylinder, reel or similar winding-devices, the variations to the winding stretch are produced by oscillation of the thread guide.

Title: Improvements in or relating to cooking appliances
Inventor: JONES JOHN ROBERT
IPC: H03K17/28
Filed: 1965-02-13
Abstract: 1,138,837. Timing control for toasters. MORPHY-RICHARDS Ltd. 8 Feb., 1966 [13 Feb., 1965], No. 6323/65. Heading A4D. [Also in Divisions G1 and H3] In a cooking appliance, a timing circuit, controlling the cooking period, includes means mounted so as to be sensitive to radiation emitted by the material being cooked or to the ambient temperature in the appliance so as to modify the operation of the circuit. The application is to a toaster in which a thermistor, mounted near the toast and receiving radiation from it, forms part of the timing control circuit. At the beginning of the cooking operation the thermistor is sensitive to the general ambient temperature due for example to residual heat in the heating element, but as cooking proceeds it will be heated by radiation from the toast. Thus as the temperature of the thermistor rises, the cooking time is shortened. The circuit is supplied from a tapping on the heating element and essentially comprises a capacitor 9 which, from the commencement of the cooking operation, i.e. when the toast carriage is lowered to a position adjacent the heating elements which are simultaneously energized, is charged until it reaches a pretedermined voltage, when it discharges and energizes a coil to free the latch mechanism maintaining the toast carriage adjacent the heating elements and to switch off the heater. In one form of the circuit, Fig. 1, the charging rate of the capacitor is set by a variable resistor 6 and the triggering voltage controlled by the thermistor 17. The circuit includes PNP and NPN transistors 12, 13 which are non-conducting at the beginning of the heating period but which are connected so that after the capacitor 9 has been charged to a voltage near to that of the junction between resistors 15, 16 they rapidly become highly conducting and a high current passes through the coil 14. This counteracts the holding effect of coil 19 on the toast carriage latch and the carriage is ejected, the heating element supply being switched off. The discharge of the capacitor 9 is slowed down by rectifier 11 to allow the latch means to have enough time to be released. Finally, the transistors return to a non-conducting condition. The thermistor thus controls the voltage at the junction of resistors 15, 16, the rate of charging having been previously set by resistor 6. In a second form of the circuit, Fig. 2 (not shown), the charging rate is controlled by the thermistor (22) and the triggering voltage set by variable resistors (23, 25). The transistors 12, 13 may be replaced by a single PNPN device, e.g. an S C R, or by thermonic or gas filled valves.
