Title: Improvements in or relating to the production of transparent tubes of normally solidethylenic polymers
Inventor: BERRY WILLIAM
IPC: B29C48/10
Filed: 1950-09-28
Abstract: <PICT:0714915/IV (a)/1> <PICT:0714915/IV (a)/2> <PICT:0714915/IV (a)/3> Apparatus for making transparent tubes of normally solid ethylenic polymer comprises an annular extrusion die 12, Fig. 1, through which the molten polymer is extruded substantially vertically downwards in the form of a hot seamless tube 11, a mandrel 13 over which the tube is passed and thereby distended, nip-rolls 14 for advancing the tube, a bath 19 of chilling liquid into which the hot distended tube is plunged after traversing a layer of air, means for supplying chilling liquid to the space within the distended extruded tube, and means for maintaining continuously the level of the chilling liquid in the said space at a predetermined height above the level of the chilling liquid of the bath.  Thus, water at 5 DEG  C. is fed slowly through an adjustable stop-cock 17 to both limbs of a constant-level device 18 of the siphon type.  One limb 18a feeds the bath 19 which is kept at a constant level by an overflow 16, and the other limb 18b feeds the interior of the tube 11.  Limb 18b terminates two inches above the level of the bath 19.  If the level of the water in tube 11 falls, water enters through limb 18b, and if it rises water siphons out through limb 18a into bath 19.  In a modification, Fig. 2, the siphon tube 25 dips into tube 11 and into a container 24 fixed to the inside of tank T, this container being fed with water; the level of the water in container 24 is the same as the level in the tube and is three inches higher than that of the bath 22.  In another modification (not illustrated), the water of the device shown in Fig. 2 is fed not to the container 24 but to the space within tube 11.  In a further modification, Fig. 3, the constant-level device comprises a pipe 37a feeding the space inside the tube and a siphon 33 dipping into the tube and into a glass vessel 34 floating in the bath.  In all these examples the air-filled space above the liquid in the extruded tube is at atmospheric pressure, but the space may be filled with air under pressure, and this pressure may be controlled as by means of a T-piece, the end of which dips to a controlled depth beneath the surface of a liquid. The temperature of the chilling water may be between 0 DEG  C. and 10 DEG  C., or may be as high as 80 DEG  C.  Other chilling liquids are alcohols, esters and ethers.  The ethylenic polymers may include normally solid ethylene polymers, vinylidene chloride/vinyl chloride copolymers and isobutylene/styrene copolymers.  Specifications 474,426 and 656,735 are referred to.

Abstract: 374,335. Loud speakers. THORNTON, A. A., 7, Essex Street, Strand, London. -(Magnavox Co. ; Oakland, California, U.S.A.) Aug. 24, 1931, No. 23822. [Class 40 (iv).] The coil 14 attached to the diaphragm 15 of a moving-coil loudspeaker is substantially longer than the depth of the annular air gap in the magnetic field in which the coil is located. Thus the end portions of the coil are always outside the influence of the field, and a uniform number of turns in the coil is maintained in the magnetic field as the coil vibrates. With this arrangement, the impedance remains constant, and lowfrequency response is improved. In the construction shown, the coil 14 is centred by a support 16 in the annular gap between the central pole 12 and the surrounding pole 11 of a pot magnet. The end of the inner pole 12 is formed as a disc-like member of the same thickness as the plate 11, though this detail is not shown in the Figure. The ends of the coil are brought along the support 16 to terminals 18, 19.
