Title: Improvements in sink-and-float separators
Inventor: HOWARD ALLAN MAURICE
IPC: B03B5/62
Filed: 1954-05-10
Abstract: 777,047. Washing granular materials. NORTONS-TIVIDALE, Ltd. Aug. 10, 1955 [May 10, 1954], No. 31152/53. Class 82(2) In a "sink and float" process and apparatus, the heavies come to rest on a surface 6 which slopes upwards to above the surface of the liquid medium, and are removed (at 32) by vibrating the sloping surface to move them up the slope. Preferably the bottom of the bath is the said sloping surface and the whole bath is'vibrated; alternatively the surface 6 may be the bottom of a trough mounted within a stationary bath and into which the heavies are directed by the upper side walls of the bath. Preferably also there are narrow openings in the surface 6 and an upward flow of liquid medium therethrough. In Fig. 1, the sloping surface 6 comprises parallel bars along the length of the slope and separated by narrow slots (8, Fig. 2, not shown). An electric magnetic or mechanical vibrator (or vibrators) 10 fixed to the side walls of the bath exerts high frequency e.g. 50 c.p.s., small amplitude impulses along a line X-X which is more inclined to the horizontal than is the base 6. The bath is pivoted to a block 12 on coil springs 14 and suspended by adjustable spring ties 16 thus allowing adjustments of the slope of base 6. Liquid medium is fed through pipes 24 to the bottom of the feed hopper 26 and also by flexible pipes 20 to boxes 22, both supplies being adjustable, and leaves over an adjustable weir 28 possibly assisted by paddles &c., carrying with it the float fraction 30. The vibrations of the base 6 are said to be communicated to the liquid medium and thus assist in the separation of the sink and float fractions.

Title: Methods of telegraphy
IPC: H04L19/00
Filed: 1926-12-10
Abstract: 262,805. McCormick, F. Dec. 10, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Type-printing telegraphs. - Means are provided in a typeprinting telegraph receiver for printing alternate sentences or other sections of a message in two different colours or stvles of type. Transmitter. The shaft 2 of the transmitter is turned by a friction drive 4, 5, from the continuously driven motor 3, and carries a commutator 10 adapted to send alternately positive and negative impulses over the line wires 16, 17. When a key of the typewriter or other keyboard is depressed, a projection 9a on a type bar 9 engages a corresponding stud 7 on a drum 6 carried by the shaft 2, and arrests the latter in a position distinctive of the letter transmitted. Receiver. The received impulses after amplification energize alternately the magnets 35. 36, Figs. 2 and 3, rocking their armature 95 about its pivot 96 and so controlling the escapement of the type-wheel shaft 42, which is frictionally driven at 44. The shaft 42 thus rotates in phase with the drum 6 of the transmitter. and when that drum is arrested by depression of a type-bar the type-wheel 45 stops in a position corresponding to that of the drum. At the same time one or other of the slow-acting magnets 37, 38, ooerates and closes the circuit of the printing magnet 48. The armature 49 of this magnet rocks about its pivot 50 and on energization operates a printing hammer 54, while on de-energization it operates a tape feed ratchet 60, and a ribbon feed ratchet 91. Escape mechanism. The shaft 42, Fig. 3, is. frictionally driven and rotates step-by-step as the armature 95 is rocked by the magnets 35. 36, about the pivot 96, the arm 97 engaging alternately the teeth of the escapement wheels 41, 98. Ink-ribbon feed and shift. The ribbon feed ratchet 91, Fig. 2, feeds the ribbon 56 through gearing which is reversed when one of two clips carried by the ribbon, one at each end, actuates linkwork to shift the shaft 93 axially. The ribbon is of the two-colour type and is shifted laterally by movement up or down, Figs. 2 and 3, of the guide 62 through which it passes. The position of the guide is determined by the position of the cam 63, which is turned step by step by the pawl 66 after each energization of the magnet 68, the circuit of which includes two breaks in series, one of which is closed at 73 whenever the printing magnet 48 is energized, while the other is closed at 76 whenever the type-wheel is in position to print a full stop or other sentence-terminating character. Thermionic valve circuits.-Each impulse received over the line wires 16. 17, Fig. 2, creates a D.C. potential gradient from a to b or in the reverse direction as the case may be, thus causing current to flow in the plate circuit of one or other of the valves 18, 19, the grids of which are negatively biased. A further pair of valves 20, 21, and a final stage comprising two parallel pairs of valves 22, 23 and 24, 25, cause amplified direct current fo flow, on receipt of a line impulse, in one or other of the output relays 35, 36.

Filed: 1964-08-05
Abstract: 1,008,323. Making electrical connections; jointing by stamping; shearing; breaking. A.M.P. CORPORATION. Aug. 5, 1964 [Aug. 9, 1963], No. 31737/64. Headings B3A, B3E, B3Q and B3W. A method of crimping electrical connectors 4, joined by a carrier strip 6, to wires comprises weakening a portion of the strip 6 upstream of the crimping station, feeding the strip towards the crimping station, crimping a connector to a wire, and bending the strip to break it at the weakened portion, freeing the connector. A carrier strip 6 may be provided at each end of the connectors, which comprise limbs 8 for crimping to insulation, limbs 10 for crimping to a conductor, a spring 3, and guide fingers 11, 13. The feeding and crimping means are similar to those described in Specifications 944,469 and 944,470. The feed finger (not shown) engages holes in the strip 6, which is engaged by a spring-pressed bar 90, Fig. 14, to locate the connectors 4 against an abutment 84. A bifurcated tool 29, Fig. 16, for breaking the weakened strip is mounted on a screw 53 which secures the crimping dies 52, 54 to the ram 48, as described in the above Specifications. The strip is weakened by a shear blade 106, Fig. 4, co-operating with an edge 116 on a lower blade 110 to partially shear the connector at 20, and with a blade 121 to partially shear the strip at 16. The blade 110 is clamped by a bolt 124 and may be adjusted by rotating a polygonal spacer 122 formed with a screwdriver slot, Fig. 3 (not shown). A housing 92 for the upper blade 106 is adjustable laterally of the mechanism by turning a nut 101, Fig. 2, on a screw 100 connected to the housing. The upper blade 106 is raised by springs (Fig. 3) and is lowered by a plunger 132 carried by the ram 48. A coil spring 136, Fig. 15, is compressed as the plunger 132 engages the blade 106, followed by compression of cup springs 135 during the partial shearing operation. The breaking tool 29, Fig. 8, engages an unsupported section 14 of the strip during the bending operation breaking the strip at the weakened parts during a crimping operation, but for simplicity the limbs 8, Fig. 8, are shown uncrimped. Instead of weakening by partial shearing, portions of the strip may be removed by a punch, or by a milling operation.

Abstract: 990,807. Large-scale filters for liquids. FULLER CO. Aug. 13, 1963 [Feb. 18, 1963], No. 31988/63. Heading B1D. The Figure illustrates, diagrammatically only, apparatus including six filter beds (of which only two are shown) whose underdrain spaces communicate by means not shown. They are radially arranged around a cylindrical doublewalled core 10. Liquid to be filtered introduced at 13 passes into an annular trough 14 whence it is withdrawn, as shown on the left of the Figure, by an inlet siphon 16 communicating with a weir box 62. From the weir box the liquid flows over a weir into a duct formed by radial partitions in the double wall and flows out at 56 into the forebay 26 of the appropriate filter bed. Filtrate is received in a retention tank 36 provided with a weir. For backwashing any bed, a valve 68 is operated to connect siphon 16 to atmosphere instead of to vacuum tank 66, and thereby stop inflow. Next, a valve 72 is operated to connect a backwash siphon system (see below) to another vacuum tank 70. The backwash siphon system consists of two further ducts (52 being one of them) within the double wall, which are connected only at the top by a weir 55 (on the right of the Figure) and are closed by a cover 54. Filtrate from tank 36 (maintained at the height shown by continued operation of the remaining filter beds) passes along the underdrain spaces, upwards through the bed on the right, into horizontal backwash channels (not shown), into the forebay 26, through a port 56 into one of the backwash conduits, up the conduit and over weir 55 into the other conduit, and out of the latter by a port 58 laterally spaced (not as shown) from port 56. The liquid thus reaches an inner chamber 50 where a certain level is maintained by a weir box (on the extreme right of the apparatus) to which leads a discharge pipe 76. Vacuum for the backwash siphon systems is provided by a vacuum pump connected at 73, while that for the inlet siphons is provided by a tube 79 depending from tank 66 and opening within liquid in a tube 77 at a height H above the liquid level in chamber 50. (Tube 77 depends from tank 70 and opens within the liquid in chamber 50).
