Title: Process for the manufacture of polyester filaments having a low degree of shrinkage
IPC: D01F6/62
Filed: 1971-05-12
Abstract: 1325297 Polyester filaments FARBWERKE HOECHST AG 12 May 1971 [14 May 1970] 14439/71 Heading B5B In a process for preparing filaments having a low degree of shrinkage and low elongation at break, filaments of a high molecular weight linear polyester are stretched and passed for a total contact time of 0À02 sec. to 0À5 seconds over or around one or more rollers having a surface temperature of from 230‹ to 280‹ C. and are then allowed to relax under a tension of from 0À2 to 10 p/tex (calculated on the final filament titre). The polyester is preferably polyethylene terephthalate, a long list of precursors for other suitable polyesters being given in the Specification.  The process is preferably carried out during a continuous spin drawing process in which filaments are melt extruded from spinneret S, passed over sizing roller P and then over or around one or more rollers 1 having a surface temperature of from 80‹ to 120‹ C. to a second pair of rollers 2 having a surface temperature of from 120‹ to 220‹ C., stretching of the filaments being substantially terminated prior to the filaments passing around rollers 2, after which the filaments pass over or around a third set of rollers 3 maintained at a temperature of 230‹ to 280‹ C., the number of turns on rollers 3 being sufficient to attain a contact time of 0À02-0À5 seconds, and then pass under a tension of 0À2 to 10 p/tex to unheated rollers 4. The wind-up speed is suitably in the range 1200 to 3500 m/min., sets of rollers 2 and 3 having circumferential speeds 3À5 to 5À5 and 4À5 to 7 times respectively that of rollers 1. The draw rollers 2 may be replaced by (a) a single roller having a temperature of 120-220‹ C. around which the filaments make “ to ¢ a turn; (b) a heated plate having a temperature in the same range; or (c) jets of super-heated steam having a temperature of 175‹ C. to 450‹ C.

Title: Improvements in or relating to fly wheel starters for internal-combustion engines
IPC: F02N5/04
Filed: 1940-09-25
Abstract: 617,233. Turning-gear. WASEIGE, C. R. Sept. 25, 1940, No. 14555. Convention date, July 28, 1939. [Class 7 (v)] A fly-wheel 1 driven through a centrifugal clutch by an electric motor 78 transmits movement to an engine engaging jaw 61 through epicyclic gearing surrounding the hub of the fly-wheel and variably - tensioned resilient mechanism enclosed in the barrel 32, an independent friction clutch device being adapted to slip only if abnormal resistance is encountered. As the motor speeds up, a centrifugal band clutch 83 engages the hub 79 of the pinion 76, the drive being then transmitted to the fly-wheel 1 and through the ensuing epicyclic gearing to the claw 61. Adequate speed having been attained, the central rod 67 is moved axially by electromagnetic means compressing the spring 64 and sliding the claw 61 into engagement with the engine crank-shaft. The shock is absorbed by the spring 53, one end of which abuts a flange on a sleeve 50 while the other presses into an annular cup 47 which is internally and externally threaded or splined to engage the members 32, 50. Internally, the member 50 is splined to the sleeve 60, terminating in the claw 61. Excessive torque results in slipping at the friction clutch 39 interposed between the toothed annulus 36 and adjustable spring- pressed pins 38. Hand actuation may be effected from the shaft 88 through the pinion 86.

An electric cigarette lighter for mounting on the dashboard 2 of a motor vehicle comprises a cigarette-holding sleeve 27 arranged in front of a heating element 4, a handle 28 slidable over the sleeve 27 and coupled to a spring- returned operative portion 17 adapted to close electric contacts for energising the heating element 4, means for releasing the operative portion 17 when the heating element 4 has reached a predetermined temperature and an acoustic or luminous warning device operated by the return movement of the operative portion 17. The cigarette holding sleeve 27 is secured to the forward end of a cylindrical body 1 fixed to the dashboard 2. The heating element 4 comprises a spiral resistance mounted on an insulated support 9 fixed to the cylindrical body 1 by a pin 10 insulated therefrom. The pin 10 is connected to a metallic cover 11 embedded in the support 9 but exposed by three slots 8 in the support 9. One end of the heating element 4 is connected to three thermostatic blades 7 disposed in the slots 8 in the support 9 and the other end is connected to a pin 12 extending rearwardly through the support 9. The operative portion 17 is provided with three tongues 22 which hook on to the thermostatic blades 7 and also contact the metallic cover 11 thus connecting one end of the heating element to the pin 10, and with a spring urged contact pin 21 which engages the pin 12 and is connected electrically to a metallic casing 18 fixed to the operative portion and having cams 19 adapted to engage earthed tongues 15 on a fixed insulating member 13. The handle 28 is attached to the operative portion 17 by two sliding rods which extend through the casing 1 and are connected to a bridge 23 connected to the rear end of the metallic casing 18. In operation a cigarette is inserted into the sleeve 27 and into contact with the heating element 4 and the handle is pulled out to cause the tongues 22 to hook on to the thermostatic blades 7. The handle is then released and when the heating element reaches the predetermined temperature the blades 7 expand and release the tongues 22 so that the operative member 17 returns under the action of springs disposed between the fixed member 13 and the bridge 23 to open the electric circuit and to cause the cams 19 to actuate the clapper 31 of a bell 3 on the end of the casing 1.
