IPC: D06F39/00
Filed: 1962-02-14
Abstract: 973, 582. Dubbing magnetic recordings. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 14,1962 [Feb. 17, 1961], No. 5665/62. Heading G5R. To prevent instability arising from magnetic coupling between heads 4, 14, when the head 4 is playing back a pack 2 for dubbing on to a track 3 together with signals supplied from a source 10 and admixed therewith, the head 4 is tuned to some 7 kc/s by a capacitor 15 and the amplified signal is fed to the stage of the second channel recording amplifier 8 at the pre-emphasis point. The dubbing facility may be disabled by earthing the junction-point of two isolating resistors 6, 7. The arrangement may be duplicated such that track may be dubbed on to track 2, the disabling button 9 then applying to both networks.

Yarn 12 having a thermoplastic component e.g. continuous filament thermoplastic yarn is drawn between first and second devices such as draw rollers 18, 19 the yarn being heated by the drawing process and then being fed through a short distance, e.g. less than 20 cms., to a device which crimps the softened yarn by linear compression e.g. a stufler box crimper 26, 29. The draw rollers 18, 19 are each associated with a skew roller 17, 20 so that the several turns about each roller are spaced. Between draw roller 19 and the nip rollers 21, 22 of the stuffer box 26, 29 is a tubular guide 23 which has bell ends and a longitudinal slot to facilitate threading up. The guide may be heated to maintain the yarn in its softened state. The yarn in the stuffer box is heated by means 29 The separation of the axes of rollers 18, 19 is less than twice and preferably less than the sum of their diameters. The diameter of rollers 18, 19 is preferably at least twice the diameter of the nip rollers 21, 22. The separation of rollers 18, 19 is preferably greater than the separation of roller 19 and nip rollers 21, 22. As shown the yarn passes from a bobbin 13 via a tensioner 14 and a driven roller 16, to the draw rollers 18, 19. The speed of roller 16 is equal to or greater than the speed of roller 18, which is less than the speed of roller 19, the speed of nip rollers 21, 22 is equal to the speed of roller 19. The plug of yarn leaving the crimping chamber is sensed by optical means 39, 40 and the speed of roller 37 driving the take-up package 35 is varied accordingly to maintain the head of the plug between the means 39, 40. A snubbing pin may be positioned between the drawing rollers to limit the size of the drawing. region.

Abstract: 754,345. Operating clutches. REGIE NATIONALE DES USINES RENAULT, Feb. 26, 1954 [April 27, 1953], No. 5794/54. Class 80(2) The frequency of a press or other intermittently clutched machine, whilst in continuous operation with the start pedal 21 depressed, is adjusted by varying the clutch-release dwell at top stroke by selection amongst a group of cam-plates 9 fast on a shaft 8. driven through a chain 4 and worm gear 5 by the driving flywheel 2 and operating through an arm 16 a switch 19 or valve in series with a start-pedal switch 21. In the electro-pneumatic form shown, engagement of the clutch 26 at top stroke is dependent on closure of both the manual start switch 21 and cam-operated switch 19 which latter occurs every time a cam lobe 10 on a selected cam-plate 9 pivots the arm 16, thus providing a dwell period dependent on the number of lobes on the armature cam-plate 9. Dwell adjustment is by-moving the switch-arm 16 axially along its splined shaft 13. by a handle 14, to bring it opposite a different cam-plate 9 having a different number of lobes. Figs. 4 and 5, not shown, are an all-pneumatic equivalent.

A gas cooler particularly for cooling cracked or other hot gases, comprises upright parallel tubes 5 having their ends secured by closure members 2, 3, the tube assembly being contained within a casing 1 in which a body of coolant water is located. The level 11 of the water within the casing 1 is controlled, e.g. by a float valve (not shown), the space above the water constituting a steam chamber, in which are baffles 13 with openings 15 disposed in staggered relationship, which force the steam to describe a tortuous path generally transversely of the tubes 5. The steam is thereby dried and slightly superheated by the tubes. At least the lower closure members 2 may comprise a plurality of hollow elements 4 into which some of the coolant may flow, as described in Specification 1,129,588. Apertures 10 which allow the coolant water to enter the hollow elements are provided around the tubes 5 in the hollow elements 4 (Fig. 2) and further holes (18) may be provided in the inwardly facing sides of the hollow elements (4) to cause a circulation of coolant through the hollow elements. The casing may be formed with an upper section 19 of larger diameter to increase the capacity of the steam chamber. Short tubes 17 may be employed in the region of the water level to protect the tubes 5 from corrosion.
