Title: Improvements in or relating to extrusion dies for the production of tubular films
IPC: B29C48/10
Filed: 1961-11-14
Abstract: <PICT:0929200/IV(a)/1> An extrusion die for extruding thermoplastics into seamless tubular films comprises an adaptor (1 in the preferred embodiment illustrated), a die body 2 and a die head 3, and is adapted to be concentrically mounted, e.g. by at least two bolts 36, over the cylindrical cavity of an extruder 4 in which is mounted a rotatable conveyer 5 having a conical tip 10.  The extrusion die has, in communication, a converging passageway 13 a cylindrical passageway 15, a diverging passageway 19, an annular passageway 18 and a diverging annular passageway 41, the cross-sectional area of which is less at its exit end, forming at its tip, an adjustable die orifice 32.  The cross-sectional area perpendicular to flow of the thermoplastic material at any point of the passageways up to the entrance of the diverging annular passageway 41 is substantially equal, and also equal to the cross-sectional area, perpendicular to flow, at any point of the cylindrical cavity of the extruder, defined between barrel liner 6 and conveyer worm 5.  Conical plug 16, threaded at one end to engage die head 3 is conveniently attached to the die body by three separate 1/2 inch wide metal pieces, e.g. 21. These pieces may also house wire 22 connected to heater 23 inserted in the plug.  The die may also be heated by further heaters, e.g. band heater 24.  The temperature of adaptor 1 may be determined by thermocouple 25.  The size of adjustable orifice 32 is varied by tensioning or loosening bolt assemblies 30 upon members 28 and 29 of circumscribing bifurcated flange 27.  Film of varying thickness down to 1 mil. or less may thus be produced.  The extrusion die may also be provided with a passageway through which air or other gas may be passed and introduced into the interior of the tubular film.  Plate 35, having nut 40 may be used to facilitate threading die head 3 on to die body 2, and removed before operation of the die.

Abstract: 1399923 Extrusion blow-moulding B STRONG 1 Sept 1972 [27 Dec 1971] 40734/72 Heading B5A Extrusion blow moulding apparatus comprises frame 1A, 1B, 19, 2A, 2B, 27 on which are mounted carriages 3, 5 connected by rods 22A, 22B and traversed on rollers 9, 11, respectively, in a horizontal path by rod 13 of cylinder 12. Front cylinders 4A, 4B with mandrels 14A, 14B and blowing air orifices 10A, 10B are mounted on carriage 3. Carriage 5 carries extruder 6 with crosshead 7 with pre-blow orifices 8A, 8B and rear cylinders 4C, 4D having mandrels 14C, 14D and blowing air orifices 10C, 10D. Rods 17A, 17B carrying heated knife 15 are also carried by carriage 5 and traversed by cylinder 18. A front platen 33 carries mould halves 16A, 16E mating with mould halves 16B, 16F, respectively, on central platen 34. Also on platen 34 are mounted mould halves 16C, 16G which mate with mould halves 16D, 16H respectively, on platen 35. From the position of Fig. 1, parisons 28A, 28B are extruded between mould halves 16A, 16B, 16E, 16F which are closed to seal the lower end thereof while mould halves 16C, 16D, 16G, 16H open to release the formed articles (30C, 30D, Fig. 2, not shown) therein, platen 34 moving in the direction Y, platens 33, 35 in the opposite direction. The enclosed parisons are then partially pre-blown by air from orifices 8A, 8B (Fig. 2), leaving upper flared sections (29A, 29B) after severing thereof by rightward movement of knife 15. After stripping of articles (30C, 30D) from the right-hand station, carriages 3, 5 are traversed to the right so that blowing mandrels 4A, 4B may be lowered into the left blow moulds halves 16A, 16B, 16E, 16F to form articles (30A, 30B, Fig. 3, not shown) and fresh parisons 28A, 28B may be extruded from crosshead 7 between right mould halves 16C, 16D, 16G, 16H which are then closed and mould halves 16A, 16B, 16E, 16F opened. The new parisons are then severed by knife 15 and pre-blown as before. Bottom flash (31, Fig. 2) on the formed articles may be removed by grippers before or after mould opening. Ejection is effected by air from mandrels 14 which also sever flared sections (29) at points (32) by co-operation with the mould-parts. Sections (29) are stripped from mandrels 14 against carriage 5 as they are raised by cylinders 4 before traversing of carriages 3, 5. Extrusion is interrupted during traversing of carriages 3, 5 but may be made continuous by provision of cylinder (59, Fig. 2) which pivots extruder 6 about point (75) during this time. In Figs. 6, 7 (not shown), there is only one mould at each station requiring a stirrup (40, 41, 42) for vertical movement of right-hand blowing mandrel (38). In Figs. 8, 9 (not shown), the extruder (64) is vertically reciprocable. An electrical, mechanical or fluid pressure operated timing mechanism may be used.

Title: Improvements relating to fluid pressure operable braking apparatus for vehicles
IPC: B60T8/18
Filed: 1962-10-30
Abstract: 989,445. Fluid-pressure brakes. WESTING- HOUSE BREMSEN-G.m.b.H. Oct. 30, 1962 [Nov. 16, 1961], No. 40981/62. Heading F2F. In pneumatic braking apparatus for vehicles having a load dependent valve 1 for controlling the fluid pressure supply to a brake cylinder or cylinders 10 at one set of vehicle wheels, fluid supply to a brake cylinder or cylinders 21 at another set of wheels is controlled by a pressure proportioning valve 14-16 which is under the joint influence of a brake control valve 8 and the controlled fluid pressure supply fed to the cylinder or cylinders 10 so as to proportion the fluid pressure in cylinder or cylinders 21 relative to that in the output of the control valve 8 in a ratio dependent on vehicle load. The load dependent valve 1 is a relay valve, said to be of known type, which is controlled by pressure in a pipe 7 leading from the control valve 8 and also by the position of a lever and linkage 4 connected via a spring member 3 to the vehicle rear axle 2, so as to provide a controlled supply dependent on load from a compressed air reservoir 6 to pipes 9 leading to cylinders 10. A branch pipe 19 from pipes 9 leads to an annular chamber 117, a pressure reducing arrangement comprising a composite piston 13 and the valve 14-16. An inlet chamber 17 of the arrangement is fed from the control valve 8 via pipe 18. In operation, as pressure rises in chamber 17 piston 13 is moved to cause element 14 of the valve to close an exhaust port 15 and subsequently to open an inlet port 16 in the piston to permit air to flow to cylinders 21 until the pressure therein reaches a proportion of that in chamber 17 dependent on the ratio of the areas of piston 13 in chambers 17 and 20. This ratio is varied as pressure rises in chamber 117 so as to be dependent on the load dependent pressure in cylinders 10.

Abstract: 863,973. Variable resistors. SHIELDS, R. (Edcliff Instruments Inc.). Dec. 29, 1958, No. 41830/58. Class 37. An adjustable resistor comprises a tubular core, having a longitudinal slot in its wall, a resistance element substantially covering the slot, and a threaded shaft passing through the core, carrying a contact element a finger of which extends through the slot to engage the resistance element. As described, a tubular core 12 has a resistive winding 15 wound about it, and a longitudinal slot 14 formed in the wall, through which projects the contact 30. The contact is mounted on the sleeve 31, threaded on to the shaft 16, having a boss 32 to which the contact is fixed. The shaft has a moulded plastic end-piece 17 at one end, which is supported in one end of the outer casing 10, and the other end bears against a thrust bearing 22 retained in a bore 25 in a plug 23. The bearing 22 is a conductive disc, preferably silver, to which a lead 27 is attached. The end-piece 17 has a slot 21 for screw-drive adjustment or alternatively may extend out of the casing for adjustment by other means. Longitudinal movement of the shaft is prevented by spring 18 and the resistor may be sealed by inserting an 0-ring 20 such that it is compressed by the spring. A backer strip 36 is cemented to the coil overlying the slot 14 and may serve to carry the lead from the front end of the coil to the lead 38. The strip, the inner face of which is slightly convex, may either be of conducted material insulated from the coil or alternatively may be of insulating material and carry a conductor printed on it. In an alternative form the wire wound resistance may be replaced by a resistive coating on the convex inner face of the backer strip.
