Title: Improvements in or relating to a method and machines for the manufacture of metal shot
IPC: B22F9/08
Filed: 1949-08-06
Abstract: 663,595. Granulating metal. AMERICAN WHEELABRATOR & EQUIPMENT CORPORATION. Aug. 6, 1949. No. 20495/49. Class 82(ii). A machine for the continuous production 'of steel shot comprises means to direct a continuous flow of molten metal against an imperforate surface which is given a compound movement consisting of a rapid vibratory movement normal to the surface and a translatory movement parallel thereto. As shown molten metal from a spout 2 falls on to the end surface of a drum 22 which is mounted in a water-cooled cylinder 21 supported by rods 37 and 38 on an eccentric sleeve 36. The cylinder 21 has a rod 14 slidable in a sleeve 12 pivoted at 13 to a support 11. Rotation of the eccentric 39 produces a vibratory movement of the drum and a swinging movement about the pivot 13. A ratchet 60 and pawl 58 operated through gearing from the eccentric drive shaft 40 rotates and moves the surface upwards to allow for wear and maintain the height h constant. The surface may be of ceramic or graphite or may be of watercooled metal having a layer of carbon thereon produced by an acetylene burner, Fig 3 (not shown). In a modification Fig. 4 (not shown) the drum may be rotated horizontally, the metal falling on the periphery, and may be given a vertical vibratory movement by a rod mounted on an eccentric.

IPC: C01B3/36
Filed: 1928-07-14
Abstract: 294,113. Battig, R. July 16, 1927, [Convention date]. Grant of Patent opposed. Hydrogen.-The methane fraction obtained in the fractionation of coke furnace gas is converted with steam or oxygen, or both, into carbon dioxide and hydrogen. The resulting mixture is washed with water under pressure. to remove the carbon dioxide. It is then cooled to -70‹ C. to remove the water and further cooled, either indirectly with liquid nitrogen or by the evaporation of the constituents of the gas itself, and thereby fractionated into its individual constituents. The resulting hydrogen fraction is treated directly with liquid nitrogen in order to remove the last traces of methane, oxygen, and carbon monoxide. By suitably controlling the pressure and temperature whilst scrubbing with liquid nitrogen, a resultant gas consisting of one part of nitrogen and three parts of hydrogen and suitable for use in the synthesis of ammonia maybe obtained. Reference has been directed by the Comptroller to Specifications 3776/85; 124,824, [Class 8 (ii), Air and gases, Treating &c.]; 231,218; 231,444. 238,175 and 242,583, [all in Class 8 (ii), Air and gases, Treating &c.]; 244,730: 248,377, [Class 8 (ii), Air and gases, Treating &c.] ; 254,713, 274,610 and 288,662.

Abstract: 879,514. Air-break switches; oil-break switches; switchgear structures. GENERAL ELECTRIC CO. Ltd. May 19, 1959 [June 27, 1958], No. 20678/58. Class 38 (5). An isolator suitable for use with the oil circuit-breaker described in Specification 879,511 is arranged to be plugged into and interlocked with the latter in place of the breaker coverplate. To facilitate this an insulating base 5 is mounted over the breaker cable terminals 4 and carries fixed contacts 11 connected to the latter. An insulating wall 7 carrying insulating boards 10 is secured to base 5 and carries fixed contacts 14 and cable cleats 15, contacts 11, 14 having a double-spring V-shape. The isolator comprises a housing 1 carrying an insulating base 18 from which project fixed knife contacts 16 to engage contacts 14 through holes 9 in an insulating member 8. Base 18 also carries fixed conductors 22 which slidingly engage the spring- controlled ends of moving contacts 23 mounted on a rotatable bar 25, the other ends of these contacts engaging the fixed contacts 11 when the isolator is closed. In this position closure of the breaker causes a slot 30 in a metal plate 29 of the breaker latching mechanism to engage a pin 31 on a plate 32 rotatable with the bar 25, thus preventing the opening or removal of the isolator. This arrangement also prevents closure of the isolator when the breaker is closed, by the engagement of pin 31 with the top of plate 29. Contacts 16, 22 may be connected by shorting strips or by high-rated cartridge type fuses and screened instruments may be fitted to the isolator if desired. The isolator may alternatively be plugged into the side or back of the breaker. Specification 879,513 also is referred to.

Plant; gravity-separation apparatus; aerating. -A single mechanical fluid-moving device, such as a scoop wheel, a paddle or an Archimedean screw pump, is used in a sewage circulation system to provide the necessary energy for the circulation, for aeration and mixing and for the return of activated sludge to the system. The sewage is delivered to preliminary sedimentation tanks b, c, Fig. 1, from which it passes over weirs j, and through an apertured diaphragm l and a pipe m to a cross-channel p connecting endless treatment channels n, o. Each of the treatment channels is provided with a fluid. moving device q and agitating arrangements s. A portion of the liquid is continually passing away through cross-channels p<1> and pipes t to settling-tanks u. Liquid is discharged from the settling-tanks over weirs v and through a pipe w, which may be provided with a gauge x. Sludge is continuously discharged from the settling- tanks, through a pipe z, part passing into a detritus pit g, whch also receives the settled matter from the tanks b, c, and part being delivered to a pit b<1>, from which it is returned to the treatment channels n, o, at points near the devices q where the pressure in the channels is low. The'channels are at this part so shaped as to produce a local increase of velocity resulting in a lowering of the liquid level. The agitating arrangements s may comprise plates or other flat surfaces which form passages divergent in one direction and convergent in another, so that the liquid on one side of the channel at the up-stream side of the device is at the down-stream end below the liquid which comes from the other side of the channel. Paddle wheels, having parallel or helical blades, and caused to revolve by the velocity of the liquid, may also be provided to agitate and aerate the liquid. Such paddle wheels may be mounted on displaceable bearings which can be inserted as desired at any part of the channel. The devices q may be scoop wheels having paddles with adjustable rubber edges. Fig. 3 shows a single endless treatment channel with multiple convolutions. It may be constructed on a horizontal surface and its width may vary, so that a constant liquid cross-section is maintained although the liquid head is lowered in the direction of flow.

Filed: 1965-05-19
Abstract: 1,114,381. Making tubular components by winding. C. F. LATTER. 19 May, 1965 [22 May, 1964], No. 21210/65. Heading B8G. [Also in Divisions F2 and G3] A machine having a power train for moving a workpiece, and a head that can traverse the workpiece, includes programming means operated by said power train for controlling the traverse of the head, there being provision for a dwell period of the head. In Fig. 1 the disc 25 rotates with the mandrel 12. The disc 25 has a large number of holes 31 on a first circle and a lesser number of holes 33 on a second circle. Each circle of holes is scanned by separate light activated switches 106, 116 responsive to light beams passing through said holes. On each actuation of the switch 106, associated with the holes 31, a motor 23 is pulsed by an increment to cause a belt 26 to move a filament winder head 18 by an increment along the mandrel 12. The number of holes 31 and the pulsing of the motor 23 can then be selected to give the desired helix angle of the winding. Whilst the head 18 traverses between limit switches 27R and 27F the light-sensitive switch 116 is not active. When one of the limit switches 27R, 27F is actuated, the light-sensitive switch 116 is rendered operative. When a first hole 33 passes the switch 116, a pulse is generated that renders the light-sensitive switch 106 inoperative and the mandrel 12 thus rotates for a period whilst the winder head 18 remains stationary. When the next hole 33 passes the switch 116, the light-sensitve switch 106 is again rendered responsive to the passage of the holes 31 and the winder head 18 re-commences its incremental movement but this time in the opposite direction of traverse. The dwell period created by the holes 33, at each end of the traverse, ensures that each successive end of filament that is wound lays adjacent to, or is disposed in a predetermined pattern with respect to, the preceding winding. The electrical control circuits are described.
