Title: Improvements relating to blasting cartridges
IPC: F42B3/06
Filed: 1946-07-25
Abstract: 615,115. Blasting-cartridges. CARDOX (GREAT BRITAIN), Ltd., and IGNATIEFF, A. July 25, 1946, No. 22150. [Class 9 (i)] Relates to an improved cap or head for a blasting-cartridge having a charge confined in a casing. According to the invention a cap or head for a blasting-cartridge has a positively held disc or sleeve, or a valve closing a transverse discharge port/or ports in the head until the disc or sleeve is ruptured or the valve opened by increased gas 'pressure caused by energization of the charge, the charge itself extending into the cap or head. A discharge cap having a metal body 1 with a threaded portion 2 for assembly in a cartridge casing 4 has a bore 7 communicating with a reduced bore 8 leading to a transverse passage 9 extending to the exterior of the cap, Fig. 1. The passage 9 is closed by a metal disc 12 seated on an annular shoulder 11, a sealing ring 13a being provided between the disc 12 and shoulder 11. A sleeve 13, which may have flats to facilitate turning by a key, is screwed into the passage 9 to hold the disc and sealing ring in position. The bore 15 of the sleeve 13 provides the discharge port of the cap and may be tapered outwardly to facilitate passage of the sheared-off disc 12. The blasting charge fills the casing 4 and in addition the bores 7, 8 and the inner portion of the passage 9. The discharge cap may be made integral with the cartridge casing, in which case the bore 7 is made parallel with the casing bore. In another form, Fig. 4, the cap is made in two sections, the forward section 18 being screwed into the other section 19 and having a reduced inner end extending into a sleeve 20, which normally closes a transverse discharge port 23a. The charge fills the axial bore in the head and sleeve and on energizing of the charge, the discharge gases shear a disc in the sleeve 20 and escape through the port 23a. In a modification, Fig. 7, the sealing disc is replaced by a valve of mushroom form, the head of the valve being seated on an annular shoulder 25 formed by a transverse counter bore 26 in the cap. A sleeve 27 holds the valve in position until pushed off its seating by the discharge gases which escape round the valve head to an annular space 31 communicating with discharge ports 30 leading to the valve stem which is tubular and communicates with the exterior of the discharge head. A spring 32 in the space 31 normally holds the valve on its seating. In another form the valve is arranged within the discharge head in alignment with the cartridge axis and normally closes the axial passage communicating with the main cavity in the cartridge casing. When lifted from its seating by the discharge gases it uncovers transverse discharge ports.

Title: Process for continuous multi-stage countercurrent extraction
IPC: B01D11/04
Filed: 1951-09-24
Abstract: In a process for the continuous extraction of two liquid phases of different density in a multi-stage mixing column, the extracted phases leaving the top and the base of the column are each passed to a centrifuge wherein the contaminating <PICT:0699133/III/1> phase withdrawn from the column is separated and thereafter returned to the column.  As shown, the heavy phase S is pumped into the top of an extraction column by a pump PS and the light phase l into the bottom of the column by a pump Pl.  The extracted light phase which is still contaminated with heavy phase is conducted from the top of the column to a centrifuge 1 from which the light phase is removed as an end product while the separated heavy phase is returned to the top of the column by means of a pump Ps1.  The heavier phase at the bottom of the column is similarly treated by centrifuge 2, the contaminating light phase being returned to the column by means of a pump Pl1.  In each stage of the tower, light liquid is drawn axially from the stage below and heavier liquid from the periphery of the stage above by a rotary pump P, the mixed liquids being fed into the corresponding chamber via a tangentially disposed inlet M.  Heaters or coolers K may be included in the circuits to control the temperatures in the various stages.  The apparatus may be used in the refining of a mineral oil with fuming sulphuric acid to produce white oil, if desired under pressure.

Title: Improvements in or relating to processes and apparatus for degasifying liquids
IPC: F16K24/04
Filed: 1927-08-25
Abstract: 276,987. Soc. Italiana Pirelli. Aug. 31, 1926, [Convention date]. Spreading liquids. - Liquids such as transformer oils are degassed by spreading them in thin layers having large surfaces by centrifugal force, within a container which is exhausted by a vacuum pump. The vessel 1 contains a number of fixed conical surfaces 4 which alternate with conical surfaces 3 carried by a rotary spindle 2. The inlet 6 for the liquid has a valve 11 controlled by a float 8. The pipe 5 is connected to the air pump. The liquid drops near the centre of the top rotary plate 3 and is spread out in a thin layer; it escapes over the upper edge and drops on to the first fixed plate 4 along which it travels to the centre and drops on to the second rotary plate. This action is repeated until the liquid collects in the lower part 7 of the vessel 1, and gas is drawn off through the pipe 5. When the liquid rises sufficiently to operate the float 8 the valve 11 closes the inlet 6 to stop the supply of liquid. During the operation of the machine, the whole apparatus, or the liquid only, may be heated to assist the de-gassing operation. A suitable container for the de-gassed liquid is shown in Fig. 2 and has corrugated metal walls 14 secured to metal rings 13.

Title: Improvements in means for and method of forming design stitch patterns on knitting machines
IPC: D04B15/04
Filed: 1967-05-15
Abstract: 1,148,217. Knitting. TEXTILE MACHINE WORKS. 15 May, 1967 [23 May, 1966], No. 22510/67. Headings D1C and D1K. Cable stitch patterning is produced on a straight-bar machine by transferring stitches of a group in a single course in opposite directions so that they cross each other to form the cable effect; the transferring being achieved by a single transfer point operated to successively transfer the loops in a single course. The machine has single point transfer mechanism as  described in U.S.A. Specification 2,182,220, comprising a single transfer point 25 or a number of such single points 'spaced across the width of the division each of which is secured  to. a bar 26 controlled by a pattern chain arrangement 41 adapted to be racked to position the point at any desired position over a group of needles. The point or points is or are normally held inoperative by a vertical cam bar 77 retaining the bar 26 in an inoperative position,. On cable stitch patterning being desired the bar 26 is released and a fashioning motion given to the points by shogging the main cam shaft 17 causing a follower 107 to engage one of a number of cams 115 and 118. During normal knitting and fashioning the follower engages cams 111 and 112 and is not operative to effect cabling. The follower, however, is capable of being shogged onto the cams 115 and 118 which control the sleeve cam of a unit 47 causing the individual points to move one or three needles in either direction. By suitable manipulation, therefore, the point bar first transfers a loop of a group in one direction followed by an adjacent loop being transferred in the opposite direction. The other stitches are transferred three needles in the opposite direction whereafter single needle transfer is achieved of the origirial loops to provide the cable effect as illustrated in sequence in Fig. 11. By provision of double needle spacing on a half gauge machine coarser patterning can be achieved.
