摘要： 652,443. Stuffing-boxes and substitutes therefor. UPTON, E. J., and FISHER, J. W. May 26,1948, No. 14229. [Class 122(v)] In a pressure gland assembly for a rotatable shaft 8 extending from a high pressure zone to a low pressure zone, a flange 10 fixed to the shaft 8 engages a fixed gland seating 11; a sleeve 24 fixed against rotation but capable of slight lateral movement with the shaft 8 fits closely about the shaft 8 on the low pressure side of the flange 10; and a chamber enclosing the part of the shaft 8 between the flange 10 and the sleeve 24 is supplied with a liquid at a pressure at least as great as that in the high pressure zone, the sleeve 24 forming a slowly leaking closure between the chamber and the low pressure zone. An oil reservoir 22, communicating with the high pressure zone via the tubes 7, 42 and with the chamber via a pipe 23 is arranged higher than the chamber so that a pressure is obtained in the chamber, greater by the hydrostatic head, than that in the high pressure zone. Oil leaking past the sleeve 24 collects in a cup 27 from which it flows to a reservoir 43 to be pumped by hydraulic pump 44 back to the reservoir 22. In a modification of a further embodiment, a packed gland which can be adjusted to cancel the leakage takes the place of a single sleeve.

摘要： A jet assembly for the extrusion of artificial filaments and like products comprises a jet having extrusion orifices therein, and a plate finely spaced from the inner surface of said jet, said plate being perforated, at a distance across the face of the plate from any of said orifices, for the passage to the inner surface of said jet of material to be extruded. The plate may be spaced from the jet by means of a washer or by the provision of integral projections on the plate or inner surface of the jet. The jet must be of sufficient thickness to withstand the pressure developed, and in order to obviate long holes forming the orifices, the inner surface of the jet is recessed at the points where the orifices are formed. The complete assembly may be used for the melt-spinning of polyamides. As shown, a steel disc 1 is drilled with six holes 2 on centres equally spaced from the centre of the disc, and at the bottom of each hole and coaxial with it is a spinning orifice 3. A washer 4 separates the disc from a second hardened steel disc 5 having a central hole 6. 1, 4-5 are clamped together by means of a heavy internally flanged nut 7 against the end of a flanged screw-threaded pipe 8 which supplies the spinning material to the assembly.
