Title: Improvements in and relating to circular knitting machines with duplex cylinders
IPC: D04B9/10
Filed: 1920-03-09
Abstract: 164,492. McGeorge, J. C., and McGeorge, D. March 9, 1920. Circular machines; knitted fabrics.-Relates to the use of an auxiliary pattern mechanism in machines with two end-to-end needle cylinders, in order to increase the range of patterns that can be given to the articles being knitted, and in particular to knit a kind of honeycomb or basket pattern composed of two courses 1/1 rib and one course plain, followed by two courses 1/1 rib reversed and one course plain, and so on. The sliders or jacks are shifted as required in order to transfer from the top cylinder to the bottom or vice versa by a cam a driven by pawls d, d<1> acting on ratchets c, c'. The pawls d, d<1> are mounted on reciprocating bars e, e<1> driven by means of bell cranks f, f<1>, links l, l<1> and levers k, k<1> from cams on a rotating part j of the ma,- chine. The pawls d, d<1> are put into or out of engagement with the ratchets c, c<1> by a spring- controlled lever m actuated by a cam m<1> on a shaft n. The shaft n is rotated according to the setting of the lugs on a pattern chain o which passes under a spring-controlled lever q and moves the opposite end q<1> into or out of engagement with a pawl r. The pawl r operates a ratchet r<1> on the shaft n. The sliders operating the needles are of two kinds, i.e. with high or with low butts, and when it is required to transfer needles carried by low batted sliders from one cylinder to the other it is necessary to actuate all the sliders by one cam plunger v or the other, according to whether the movement is to be up or down, and then to return the high butted sliders. Thus in transferring the needles carried by the low-butted sliders to the top cylinder, all the sliders in the bottom cylinder are acted upon by the cam v which is thrust in towards the bottom cylinder by means of connections v<2>, v<1>, t<1> and a lever s, the right-hand end of which engages with projections on the cam a. The return of the needles carried by the high-butted sliders from the top cylinder is effected by means of connections which are acted on by a series of projections on the cam a. The projections are of two different heights, and the lower projections enable the high-butted sliders to be operated independently of the low-butted sliders.

Title: Treatment of molten ferrous metal with oxygen and solid refining agents
Inventor: LAMB LEONARD DOUGLAS
IPC: C21C5/32
Filed: 1962-02-23
Abstract: <PICT:1014803/C6-C7/1> In a process for the treatment of molten ferrous metal with oxygen and solid reagents the latter in the form of powder are fed through the inner tube of a concentric double lance, while a high pressure stream of oxygen is fed through the other tube, which terminates in a nozzle so shaped that mixing of the powder with the oxygen stream occurs before the latter contacts the metal surface.  Solid materials used include lime, fluorspar, iron ore, desulphurizing agents, alloying elements or carbon, and the feed may be assisted by a flow of atmospheric air.  The process may also be applied to mixed charges of molten metal and solid scrap, the latter melting as the reaction proceeds.  A suitable apparatus illustrated comprises a tube 10 attached to the base of closed hopper 11, the bottom 12 of which is of porous material to permit the influx of air.  Tube 10 is surrounded by tube 13 through which oxygen is supplied by inlet 14 and which is restricted in diameter at its lower end 15 to form annular nozzle 16. Tube 10 is tapered at its lower end whereby nozzle 16 produces sub-atmospheric pressure at the end of tube 10.

Filed: 1945-03-22
Abstract: 603,715. Velocity-modulated tubes. BARFORD, N. C. March 22, 1945, No. 7317. [Class 39 (i)] An electron discharge device of the velocity modulation type comprises a coiled length of waveguide with apertures through which is projected an unmodulated beam of electrons. In Fig. 3, the waveguide is coiled in a helical manner, and the electron beam is projected through apertures 2 in adjacent walls arranged in a line parallel with the axis of the helic. The whole coil may be enclosed in an evacuated envelope, or the apertures and electrodes may be enclosed, the remainder of the waveguide being external to the envelope. Alternatively, the first aperture, the cathode and focusing electrode are enclosed in one envelope and the last aperture and anode in another, the guide being evacuated and the ends sealed. More than one series of apertures 2 may be provided, and their shape may be circular, arcuate or even annular. In Fig. 4, the electron beam passes down the axis of the coiled waveguide, a helical slot 6 in the wall yielding a continuous interchange of energy between wave and electron beam. The wall mav however be omitted entirely. The pitch of the coils may be constant or variable, preferably the latter to compensate for the slowing down of the electron beam. The helix may be square and the cross-section of the wave guide may vary from circular to square. The devices can be employed as amplifiers, as mixers of high frequency waves to give an intermediate frequency, as detectors for modulated waves and as generators of self-maintained oscillations ; in the latter case, a coupling is provided between the ends of the coil such as a cavity resonator chosen to give fine, coarse or wide band tuning or one end of the guide is closed so as to set up a system of standing waves.

Patent GB-830233-A (GB)
Title: The treatment of sulphide ore
IPC: C22B1/02
Filed: 1957-03-06
Abstract: Sulphur is recovered from pyritic iron ores by distilling off the labile sulphur in a distillation zone, and roasting the resulting material in a roasting zone, characterized in that a major portion of the roaster gas, composed mainly of nitrogen and sulphur dioxide, is removed from the roasting zone, or from a point between the roasting and distillation zones, cooled, and returned to the roasting zone, and that a minor portion of the roaster gas is passed to the distillation zone, where the sulphur dioxide is reduced, the heat of reduction providing the major portion of the heat for the distillation of the labile sulphur, the distillation being carried out without sintering or melting of the ore.  The process may be carried out in shaft furnaces or in fluidized beds.  Any non-ferrous metals in the ore may be sulphatized in the roasting zone by the recycled cooled gases. The sulphur dioxide may be reduced in the distillation zone by gaseous reducing agents, which may be derived from pig-iron furnaces or coke oven gas, and may be introduced at a point at or below the distillation zone.  Solid reducing agents may also be employed.  The raw material may be briquetted and have incorporated in it salts, such as magnesium chloride and sulphate, calcium chloride, and sodium sulphate, which have a catalytic effect on the conversion of nonferrous metals to water-soluble compounds during sulphatizing.  The roasted material may be leached or subjected to a chlorodizing roast to recover the non-ferrous metals.
