Abstract: 752,555. Reduction of iron ores. KANAMORI, K., and YAWATA SEITETSU KABUSHIKI KAISHA. Jan. 4, 1954 [Aug. 10, 1953], No. 172/54. Class 72. The temperature of molten pig iron in the hearth of a blast furnace is controlled by forcing water in the liquid phase and under pressure directly into the liquid metal. As shown, a downwardly inclined tuyere 2 has a tube 3 passing through it into the liquid metal 4 in the hearth of a blast furnace 1. Water under pressure in a tank 5 is fed into the tube 3 and at the same time a gas, e.g. oxygen, nitrogen or carbon dioxide or a mixture thereof, may be passed through the tube. A carbon tube having a closed end in the molten metal and an open end outside the furnace may be used to obtain the metal temperature by the use of a pyrometer, Fig. 2 (not shown). By control of the oxygen in the gas-water mixture, oxidisable impurities, e.g. chromium, in the metal may be removed.

Abstract: 340,143. Automatic -- feed weighers. NAGEL, C., Gliesmarode, near Braunschweig, Germany. Jan. 6, 1930, No. 450. [Class 143.] In an automatic weighing machine of the type wherein the weighing receptacle discharges its contents by rotating or tipping and is coupled after the completion of the filling, with a mechanical drive which causes its emptying, the coupling of the weighing receptacle with the mechanical drive is effected bv the feed gate regulating the supply of material to the weighing receptacle. When the filling of the weighing receptacle 5 is completed the final cut-off flap 14 closes in known manner, and a rod 15 operating through mechanism 16 .. 19 couples a shaft 7 to a continuously-rotating pulley 8. A slotted disc 9 at one end of the shaft rotates a crank 20 on the trunnion of the receptacle 5 and rotates the receptacle to discharge its contents. A roller 22 on the hanger 3 of the receptacle is engaged by the notched periphery of the disc 9 so as to bring the trunnion again into line with the shaft 7. Shortly before a complete rotation of the receptacle, a cam 12 actuates a lever 23 and opens the feed gates which are retained in usual manner by levers 24 .. 27, and at the same time the rod 15 is moved downwards to uncouple the shaft 7 from the pulley 8. The invention may be applied to machines wherein the weighing receptacle tilts through about 180‹.

[Also in Division G4] In an alarm of the type in which an abnormal condition is indicated by the closure of a pair of contacts 26, 30 connected to a pair of leads 15, 21 by means of a connector, spurious alarm signals due to electrolyte in the connector shunting conductors 15, 21 are prevented by means of a member 60 which shunts currents in the electrolyte back to the energizing source. The connector comprises a first member 16 carrying sockets 18, 19 to which leads 15, 21 are soldered and a second member 41 carrying plugs 22, 23 connected to the detector which may be of the type disclosed in Specification 961,147. A rib 42 is provided on the member 41 which engages with a recess 43 in member 16 to ensure correct orientation of the connector. The metal disc 60 has two holes 61, 62, Fig. 4 (not shown), through which the connector plugs 22, 23 can pass. The outer edge of the ring is in electrical contact with the metal casing 35 and is connected to the side 11 of the battery (earth). If any electrolyte is present in the connector the current flow will then connect either or both of the leads 15, 21 to earth, and indicator 46 will not be energized. Occurrence of abnormal condition to be detected, e.g. a fire, causes the detector switch 26, 30 to close, completing an alarm circuit between a battery 10 and an indicator 46, Fig. 1 (not shown). The alarm sensor 32 includes an end portion 50 which is used for testing the system. Fig. 5 (not shown) relates to a similar circuit not connected to earth.

Abstract: 1,206,353. Filter element. INDUSTRIAL FILTER & PUMP MFG. CO. 3 Jan., 1968 [25 Jan., 1967], No. 484/68. Heading B1D. A leaf filter element comprises two flat screens 36a, 36b, connected by a peripheral frame and having areas 34, 51, 52 of the screens rendered impervious; to provide gaps or weakened strips in filter cake forming on the screens, so that when the element is shaken the cake breaks into separate sheets of such shape that they fall from the vertically oriented element without impinging on other parts of the apparatus. In Fig. 3, the areas 34, 51, 52 break the cake into four sections which fall clear of filtrate manifold 27 and arcuately reciprocating liquid spraying headers 46, 47. In Fig. 2 (not shown) a rectangular element has only a vertical impervious strip, for use in apparatus without spray headers. Fig. 1 (not shown) illustrates a filter with a number of elements mounted on a common manifold 27 and shaken by a common motor 31. Before shaking, the end cover (32) of the housing is removed and the elements, manifold and shaking bar 29 are withdrawn from the housing by assembly (33). Impervious areas 34, 51, 52 have a width of about 80% of the maximum cake thickness and are formed by adhesive plastics or stainless steel strips outside the element, or by applying paint to the screens. The screens are separated by a wire grid (37) (Fig. 4, not shown), and filter aid may be applied thereto before filtering.

Abstract: 1,020,247. Sewing machines. CLINTON INDUSTRIES Inc. Jan. 4, 1963, No. 547/63. Heading D1G. A sewing machine thread-cutting device comprises upper and lower guide plates having vertically-aligned openings registering with the path of a vertically reciprocating needle, a cutter member disposed between the guide plates for movement in a liner path across said openings and having a leading edge inclined to said latter path and a rearwardly-directed thread-cutting edge, and means for reciprocating said member along said path. In a twin-needle, lock stitch sewing machine having combined needle and dog feeds, the presser foot has a lower, work-engaging plate 22 formed with needle-passing slots 24, and an upper plate 26 which is separated from plate 22 by side flanges 27 and is formed with needle-passing slots 30. A lug 34 on plate 26 is pivoted at 36 to the lower end of a bracket 18, the upper end of which is fixed in a slot formed in the presser bar 16. A thread-cutting member, slidably disposed in the space between plates 22, 26, comprises a lower blade 40 engaging plate 22, and an upper blade 39 which is secured to blade 40 and to a bar 38, and is sprung upwardly at its front end to engage plate 26. The front ends of blades 38 and 40 are bifurcated and each bifurcation has an inclined leading edge 46, while blade 40 has a rearwardly-directed hookshaped sharpened edge 44 and blade 39 has a rearwardly-directed hook-shaped rounded edge 48. A lug 49 on bar 38 is pivoted to the lower end of a stud 61 slidable in one arm 58 of a bell crank lever pivoted at 51 to a collar 50 fixed to the presser bar 16. The other arm 63 engages the ball end 69 of one arm of a bell crank lever pivoted at 66 to collar 50. The other arm 70 carries a pin 71 slidable in a slot formed in a plate 72 rigid with the spring-biased armature of a solenoid. Energization of the latter thereby moves blades 39, 40 forwardly, when the needle threads T move past the inclined edges 46 and become engaged with the hooked edges 44, 48. On de-energization of the solenoid, the blades 39, 40 move rearwardly, when the threads T are severed between edges 44 and the sharpened rear edges of slots 24, while the thread ends are held between edges 48 and the rounded rear edges of slots 30. The lower threads are simultaneously severed by a device which is the subject of the divisional Specification 1,020,248.

The radiators are spaced half a wavelength apart along the loops and some of them are connected at one end to a first loop and at the other end to a second loop, both loops being in series with the same feeder. Auxiliary radiators 10, 11, Fig. 2, may be added as shown.. In Fig. 2, the feed-wires are crossed so as to preserve the desired phase-relation whilst keeping all the feed-wires in the same plane. This simplifies the suspension of the system. Since the radiators are series-fed, the points at which the loops are connected to the feeder 5 are potential nodes, and do not require expensive insulation. The aerial system is directive in two opposite directions.
