Title: Manufacture of zinc oxide
IPC: C01G9/03
Filed: 1921-01-14
Abstract: 161,156. New Jersey Zinc Co., (Assignees of Singmaster, J. A.). March 31, 1920, [Convention date]. Dry processes of refining lead.-In the production of z i n c oxide by volatilizing zinc in a retort and burning the vapour, a substantial body of molten zinc is maintained in the retort by adding zinc thereto from time to time to replace that which has been volatilized, the zinc so added being preferably molten and at a temperature near the boiling-point. The zinc may be drawn directly from a spelter furnace, but it is preferred to feed the retorts from a separate melting furnace in which a large quantity of zinc is maintained molten so that any inequalities in composition of the zinc supplied to this furnace are equalized before reaching the retorts. A reverberatory furnace 1 contains the body of molten zinc, the metal being withdrawn as required from a dip-well 2 which has a depression at the bottom as shown in which any excess of lead beyond one per cent separates and is drawn off. An overhead track 3 supported by brackets 4, 6 carries a ladle 16 which is filled from the dip-well and conveys metal to the retorts 9 which are set in chambers 7, 8. Each retort has an inlet pipe 13 for reducing gas, having a door 14 for the insertion of a funnel 15 which receives metal from the ladle 16. The pipe 13 is luted in position by clay or the like 12 when the operation is started which is broken away when it is necessary to clean out the retort. The level of metal in the retort is maintained by intermittent feeding at a considerable depth, say half full. The outlet 11 of the retort is open, and both the reducing gas and the zinc vapour burn as they issue, the zinc oxide being collected in the usual manner.

Title: Improvements in or relating to separators for liquids having different specific gravities
IPC: B01D17/02
Filed: 1932-01-25
Abstract: 377,570. Gravity-separation apparatus. THOMPSON, H. A., Eastfield Lodge, Eastfield Road, Benton, Northumberland. Jan. 25, 1932, No. 2245. [Class 46.] Apparatus for separating liquids of different specific gravity comprises a number of communicating quiescence chambers of ovate or substantially triangular vertical cross section with the portions of greater horizontal cross section directed towards a collecting dome and the inlets to the several quiescence chambers situated near the level of greater cross section. A mixture of oil and water is supplied through an inlet 8. Figs. 1 and 4, and the water flows longitudinally through an inner shell 2 of oval cross section and then back to an outlet 9 through the space between the shell 2 and an outer shell 1 of similar cross section, oil rising into a dome 3. A flared direction plate 10 adjacent to the inlet 8 and a deflector 36 on the base of a compartment 11 create a swireing motion in the compartment which causes particles of oil to coalesce. There is a baffle 17 in the shell 2 adjacent to the opening 15 through which the water passes from the shell, and a curved plate 18 just below the opening. The space outside the shell 2 is divided into compartments by division plates 20 which do not reach to the bottom of the shell 1. Intermediate baffles 23 extend upwards from the bottom of the shell 1. Oil separating in the outer space rises through passages 22 to the dome. The discharge of oil from the dome is controlled by a valve 6 which may be operated by hand or by a float 37 connected to levers on shafts 39, 39a, the shaft 39 being also provided with a weighted lever 42 outside the casing. The lever 42 contacts towards the end of each motion with triggers 53, 54 on the spindle of a slide valve which works the valves of a pressure cylinder, the piston of which is connected to the valve 6. The piston may be moved to close position by a spring, and a connection provided so that the pressure of the liquid under treatment is used to move the piston to open the valve. Alternatively the lever 42 may control electric trip-gear or operate a mercury-tube contact switch which controls electric valve-operating mechanism. When the valve 6 is opened and closed manually the lever 42 may operate an alarm. Steam heating pipes or electric heating elements' may be provided in any of the chambers. Apparatus is described in which a filter bed is provided above the opening 15 and another filter bed in one of the compartments of the outer space. Where the liquid to be separated is heavier than the main flow, for example where water is to be separated from petrol, the apparatus is inverted as shown in Fig. 11. A glass cylinder 81 may take the place of the dome, and a float-operated needle valve may control the discharge of water from this cylinder.

Title: Improvements in or relating to the reinforcement of fabric articles by slitting and sewing reinforcements to the slit edges
IPC: D05B33/00
Filed: 1956-01-25
Abstract: 792,335. Sewing machines. TEXTILE TRIMMING & BOARDING MACHINE CO., Inc. Jan. 25, 1956 [Dec. 19, 1955], No. 2492/56. Class 112 [Also in Groups XXIV and XXX] Multi-needle machines; guides for use in attaching tapes; severing work; folding work. Tubular blanks of knitted material B and two tapes 38, 39, Fig. 1, are fed through a sewing station where the tapes are stitched in spaced longitudinal fashion to the material which is then progressively slitted between the tapes. A twoneedle chain-stitch machine S having two loopers is employed, and the slitting is effected by a knife 82, operated from the rock-arm actuating the needle-bar, cooperating with a knife-edge insert fixed in the needleplate. The tapes are fed from reels through angular guides 48 arranged in front of the needles and adapted to bend the tapes to L-form, with the vertical limbs adjacent, the stitching being performed on the horizontal limbs. Feeding work: work supports. The blanks are fed to the machine by a conveyer C arranged in a casing 21 pivotally supported at one end of the table 1. The conveyer consists of an endless canvas belt arranged around a driven roll and a longitudinally adjustable supporting roll mounted at the ends of the casing. The driven roll is intermittently rotated through a variable angle by a linkage reciprocated by the rock-arm actuating the feed dogs. A uni-directional clutch and a uni-directional brake are incorporated in the roll to effect the drive and to prevent reversal, (see Group XXIV). The top run 7 of the belt passes over a plate fixed to the casing 21 and provided with a central, longitudinal rib which forms a longitudinal peak 42 in the canvas. This enables the operator to correctly align the tapes, a marker on the blank, and the needles. The casing 21 is provided with a scale 43 and after the tapes are secured to the forward end of the blank by anchoring stitches the blank is stretched or puckered, if necessary, to ensure that its length when reinforced by the tapes will be correct. The feed-dog arrangement, Fig. 9, comprises a front-feed dog D secured to a rod 54 passing through a frame carrying a rear feed dog M. Vertical movement is effected by a rock-arm 66 connected by a link 69 to the frame. The rod 54 is secured to a head 59 and the frame 65 is connected to a sleeve 57 supported on the rod 54. Both head and sleeve are connected for movement to an arm 61 pivoted on a shaft 31 and having a hub integral with or connected to the hub of a rock-arm 30 also pivoted on shaft 31 and actuated by eccentric rod 33. The pin-and-slot connection 73, 74 in the linkage between sleeve 57 and arm 61 can be adjusted to produce a difference between the longitudinal movements of the two feed-dogs. A part 103 of the rock-arm 30 is connected by a link 105 to a plate 28 pivotally connected to one end of a link 107, Fig. 1, and coupled by a member 25 to a rod actuating the driving roll of the conveyer.

Title: Improvements in the Treatment of Sewage for the Purification thereof and the Production of Combustible Gas therefrom.
Inventor: FLICKER HORACE
IPC: C02F3/24
Filed: 1917-02-27
Abstract: 111,401. Flicker, H. Feb. 27, 1917. Aerating; plant.-A process for purifying sewage comprises charging it with air, introducing the aerated sewage over the surface of sewage contained in a tank, the downward movement of the sewage in the tank while it is subjected to bacterial resolution, the continuous discharge of the effluent, and the periodical withdrawal of sludge. The combustible gases evolved may be collected for heating and lighting purposes. In the plant shown in Fig. 2, an aerating-device 2 charges the inflowing sewage in the pipe 1 with air, and the aerated sewage is sprayed by sprinklers 3 over the surface of the sewage in a chamber 5 formed by the wall of the tank and a baffle 7. The effluent leaves the chamber 5 by a passage 6, passes across the surface of the sludge deposited in a chamber 8 so as to facilitate the liberation of gas therefrom, and leaves the tank by a passage 9 and over a sill 11 where it is broken up to facilitate the liberation of gas from it. The leaving effluent is further aerated at 106. When the sludge reaches a gutter 14, as determined by the aid of a test pipe 105, some of it is drawn off by a pipe 101. Spray pipes 104, 102 facilitate cleansing the bottom of the tank and the pipe 101. The lower edges of the baffles are serrated to provide even distribution of the effluent. Gas may be drawn off by a pipe 20, and some of it is utilized in a heater 23 from which hot fluid is passed through a coil 24 in the tank to maintain the sewage at a temperature suited to the bacterial action. A circular tank is similarly arranged, annular baffles and a central discharge pipe being provided. In the circular tank shown in Fig. 4, the aerated sewage is supplied by sprinklers 304. The effluent flows downward in a chamber 302 and under a baffle 305 to an outlet 313, while the sludge is collected in a central chamber 308.
