Abstract: 566,069. Rod - feeding machines. MULLARD RADIO VALVE CO., Ltd., and HAYES, C. F. M. March 2, 1943, No. 3426. [Class 78 (i)] A machine for feeding simultaneously a plurality of rod-like bodies from a hopper &c., e.g. pins to a mould to form leads for electric discharge tubes, has the transfer of the pins controlled by direct fluid pressure. The hopper 1 surrounds an oscillatable or rotatable drum 2 furnished with grooves on its periphery parallel to its axis and connected by ducts to its hollow centre. The rods are put in the hopper either directly or by placing thereover a filled reservoir having a sliding bottom, and, optionally, a window or transparent side. The drum 2 is integral with a hollow shaft 5 rotatable in a bearing 11 and axially slidable therein within limits imposed by stops 12, 13. Slidable on the shaft 5 is a block 6 carrying pushers 51 which force the pins 50 lying in the drum grooves nearly out of said grooves, the final expulsion of the pins and their insertion into bore-holes 21 in a transfer member 20, turnable from horizontal to vertical, and vice versa, about a hollow shaft 23, being effected by suction into the holes 21. The shaft 5 is keyed to the block 6 by press pins 15 engaging one of two notches 16 in the shaft surface, and the block is movable axially by a handle 9 slotted at 10 to engage a pin 33 which also slides in a curved slot 8 in the block 6, thus imparting also a slight rotary movement to the block 6, the drum 2 and the shaft 5. The shaft 23 of the transfer member 20 is mounted in bearings 28, 29 which are spring-pressed to cause flatted mutilated pinions to bear against racks 25 on the underside of slide bars which carry the pin 33. The journal guides 30 form with the blocks 28, 29 valves whereby fluid pressure is introduced into the hollow shaft 23 to force the pins from the member 20 into the mould. Registering pins are provided between the drum 2 and the member 20, and also for correctly locating the mould carrier. Specification 566,070, [Group XXIII], is referred to.

Title: Well perforator
IPC: F42B3/08
Filed: 1957-02-01
Abstract: 837,900. Blasting cartridges. DRESSER INDUSTRIES Inc. Feb. 1, 1957 [Feb. 1, 1956], No. 3630/57. Class 9(1) Apparatus housing hollow charges for perforating well casings and earth formations surrounding well bores is provided with means for preventing the escape of the slug formed by collapse of the metal liner of each charge after firing of the charge. The apparatus comprises a thickwalled steel tube 10 closed at the base by a tapered plug 11 and at the top by a cable head 12 and sleeve 13. A cable 16, through which extends an insulated electrical conductor 17, is anchored in the head 12 and serves to lower the apparatus into the well. The conductor 17 is connected by a conductor 18 to an electric detonator 20 housed in a sleeve 21, which is crimped over one end of a detonator fuze cord 24 and is supported by a diaphragm 23. The hollow charge units 30 are aligned with ports 25 in the tube 10, the ports being staggered around the tube e.g. the ports may lie along a helix. Each unit 30 has a cylindrical boss 33 which enters a recess 32 in the tube 10 and is held in alignment with the port 25 by a retainer 35, which engages a port seal 28. The retainer 35 is frusto-conical and has thickened ends 36, 37, the intermediate portion 39 being of flexible resilient material such as rubber or neoprene. Fuze cord 24 is threaded through a bore 63 in the boss 33 and is preferably a P.E.T.N. reinforced Primacord, while the hollow charge 45 is preferably high explosive in cast, pressed or pellet form, e.g. R.D.X. The liner 57 may be aluminium or steel but copper is preferred, while the charge housing 46 may be of metal or synthetic plastic material. The metal port seal 28 has an axial passage 65 closed at the outer end until the charge is fired. The closure 66 is then pierced by the gas jet, but the passage is too narrow to allow the subsequent escape of the slug and debris from the housing 46. In Fig. 3 escape of the slug is prevented by a member 69 which is hemispherical and has a gas-escape passage 65a coaxial with the liner 57. The member 69 is preferably made of steel. In a further modification the tube 10 has, instead of the ports 25, apertures to allow the passage of the perforating jets but of too small diameter to let the slugs pass. The apertures are counter-bored at the outer surface of the tube 10 to form seats for fluid seals. A further modification, Fig. 5, may be used in the housing 10 or as a self-contained unit. The charge 45 is housed in a fluid-tight metal shell 75 having a hemispherical shield 76 at the forward end. Coaxial with the charge is a passage 65c extending nearly to the outer surface of the member 76, the passage being opened by the jet when the charge is fired and being too narrow to allow escape of solid fragments.

Title: Improvements in marking devices
IPC: D06L4/686
Filed: 1931-02-06
Abstract: Articles of an absorbent nature, e.g. ropes, are marked for identification purposes by impregnating the article or a part thereof with a substance capable of rendering it fluorescent, or, if fluorescent substances are normally present in the article, with a substance having a fluorescence different in degree or character from that of such normally present substances.  One or more yarns of a rope, for example, may be impregnated with the sodium salt of the sulphonic acid of methylated Primuline base; such yarns are inconspicuous among the other yarns in the rope, but stand out with a whitish-yellow colour under the action of ultra-violet rays in a dark room.  Other dyes which may be used for the same purpose are Chlorazol fast yellow 5GK, Chrysophenine G, Primuline, Auramine, and Rhodamine B.  The fluorescent material may be mixed with the oil or grease which is applied to the fibre in the manufacture of the yarn, and may be more, or less, fluorescent than the oil or grease itself, so that the treated yarns fluoresce distinctively when submitted to ultra-violet light.

Title: Improvements in or relating to a method of treating furnace blacks
Inventor: CINES MARTIN RICHARD
IPC: C09C1/56
Filed: 1951-02-19
Abstract: <PICT:0689141/III/1> Furnace carbon black is treated with an oxygen-containing gas containing 0.0001 to 5 volume per cent of sulphur dioxide for a time sufficient to produce a black having a pH of 7 or less measured on degassed black, that is, after removal of physically adsorbed sulphur dioxide.  The treatment may be effected in a pelleting drum, the black being thereby pelletized, or in a fixed or fluidized bed.  Temperatures of 70 to 300 DEG F are preferred employing 5-20 cubic feet of air per pound of black and a treatment time of 10 minutes to 24 hours.  In Fig. 1 furnace black is fed from a bin 7 to a rotating pelletizing drum 6 where it is contacted with air, suitably at atmospheric temperatures, entering at 11, containing sulphur dioxide from 13.  The air may be preheated at 18 and is exhausted at 17.  The treated black pellets pass either to a storage bin 22 or to a drum 24 where the pellets are degassed by a current of air from pipe 26 before passing to storage bin 34.  The air may be passed through pipes 28 and 12 to the treatment drum 6. The treatment increases the scorch time, hardens the pellets and produces a more hydrophilic furnace black.  Specification 670,227 is referred to.

[Also in Division A2] A method of drying a foam, e.g. a food such as tomato paste or tea or fruit juice concentrates, consists in depositing the foam in a layer up to 0À1 inch thick on a moving support, applying heat by condensing a vapour on the underside of the support and passing a drying gas over the foam on the support. The layer is preferably 0À005-0À040 inch thick and the moving support is preferably an impervious, e.g. metallic, endless belt. The condensing vapour which applies the heat is preferably a mixture of air and steam, and the drying gas is preferably air at 140-210 F. moving at a velocity of 500-1500 ft./min. relative to the foam, preferably transversely to the direction of movement of the conveyer belt. At the terminal portion of the drying process the foam may be passed under an inert gas or a dessicated gas, and the end product may be treated with an azeotroping agent and re-dried. Food emulsion from hopper 10 and a foam stabilizing emulsion 12 are spread on to endless belt 26, preferably of stainless steel, by spreader 22. The foam layer passes under drying hoods 28 (see also Fig. 3) into which heated air is introduced at 29 centrally of the belt, moves transversely across the belt and is exhausted at 35. Instead of air, an inert gas may be used in the last drying hood. Under the belt, heat is applied by steam chests 30 into which a controllable proportion of air may be admitted at 33. As shown, the dried material is removed at 40, but alternatively the material may be left adhering to the belt and further drying effected by enclosing the lower run of the belt in a drying tunnel, the material being removed at the bottom of roller 23.
