Abstract: 640,174. Change-spetitt control. KESTERTON, H. M. Aug. 13, 1947, No. 22476. [Class 80(ii)] [Also in Groups XXIX and XXXV[I] In a control mechanism for variable speed gears, applicable to machine tool drives but shown as applied to a motor vehicle three speed and reversing gearing, a solid or hollow actuating shaft a is turned through a lever d by movement of the main clutch pedal (not shown) or other operating means such as a hand lever. Pairs of oppositely handed cam pieces, worm threads or, as shown. helical slots c on the shaft a co-act with pairs of plungers h in the gear operating forks e to slide the latter one way or the other to operative positions on turning the shaft a. The plungers are urged to engage the slots by leaf springs i, but are held from so doing unless cut-aways k in a rotary selector shaft f register with projections j on the springs. A fixed locking bar m has notches n in which the outer ends of each pair of plungers locate when the gearing is in neutral, whilst movement of a fork e to operative position brings the engaged plunger under the un-notched portion of the bar m and prevents disengagement. In operation, the shaft a is turned, as by depression of the clutch pedal, to neutralize the gear in operation, the shaft f is rotated manually or otherwise to change the operative plunger, and the shaft a is turned back as by release of the clutch pedal, to institute the new gear ratio. The leaf springs i may be replaced by spring-loaded levers, and either springs or levers may be biassed to disengage the plungers which are then moved into engagement by the selector shaft. The shaft f may be turned to pre-select gear ratios when a gear ratio is still in operation, such movement being allowed by the resilience of the springs i,' or, where rigid levers are used, by spring mounting on the levers of the plungers or the parts co-acting with the selector shaft

Title: Process and apparatus for manufacturing tubular films of synthetic thermoplastic materials
IPC: B29C48/10
Filed: 1964-06-02
Abstract: 1,009,294. Tubular films. MONTECATINI SOC. GENERALE PER L'INDUSTRIA MINERARIA E CHIMICA. June 2, 1964 [June 20, 1963], No. 22814/64. Heading B5B. A tubular film of a synthetic thermoplastic material is extruded in a heat-softened condition into a quenching liquid bath, pulled through the bath in collapsed condition, and, as the collapsed film tubing is pulled out of the bath in a direction which is vertical or within 45 degrees of the vertical, a spatially stationary bubble of the film tubing is formed and maintained during the extrusion process, vibrations being applied to said bubble in a direction substantially transverse to the length thereof to thereby dislodge any droplets of liquid from the inner surface of the bubble and collect them in a bottom section of the bubble. Specified thermoplastic materials include polypropylene and vinyl and vinylidene resins. A charge of solid absorbent for the liquid, suitable in granulated form, may be maintained in the bubble, preferably in the bottom section only of the bubble. Specified absorbents include silica-gel, anhydrous sodium sulphate, magnesium sulphate, potassium carbonate, anhydrous copper sulphate and activated alumina. In the Figure, a tubular film 4 is extruded from die 3, inflated with air or other gas, e.g. nitrogen, supplied through conduit 5, quenched in the water bath 6 and collapsed between collapsers 9. The collapsed film is pulled through the bath by pinch rolls 8, deflected vertically upwardly around guide roll 10 and taken up by a further pair of pinch rolls 11, placed above the tank 7. A bubble 46 is formed between the de-collapsers 13 associated with rolls 11 and the collapsers 14 associated with rolls 12. A gas such as air is contained in the bubble and transverse vibrations are imparted to the film by ultrasonic electroacoustical transducers 17, energized at a supersonic frequency by an electrical oscillator 18. A frequency of 20,000 c.p.s. is preferred. Electro-magnetic or mechanically operated vibrators may be used, operating if preferred at sonic frequencies. Thus any liquid droplets or particles of absorbent fall to the bottom section of the bubble. A charge 15 of pelletized absorbent 15 is contained in the bottom section of the bubble. When the charge 15 becomes loaded with the absorbed liquid, or where no absorbent is used, when the liquid pool reaches a certain depth, extrusion is stopped and the tube is severed. Cuts may be made just beyond points 11, 12, or a single cut can be made just below 17 and the bubble contents poured away. In the latter case, it is advantageous to support the lower pair of pinch rolls 11 and de-collapsers 13 by mounting means, indicated at 20, capable of rotation through 90-100 degrees in the direction of arrows F.
