Abstract: 445,395. Treating sewage &c. HENRY, R. A., 78, Quai de Rome, LiÚge, Belgium. April 12, 1935, No. 11353. Convention date, March 11. [Class 111] Waste liquors, such as sewage, activated sludge, &c. are purified by treatment with a suspension of clay in an aqueous solution of lime. Inert finelydivided porous materials, such as coke dust, soot and ash, may be added at the same time. The amount of line used is sufficient to maintain the pH factor of the liquid treated at 11 or above. Lime from a vat C1 and clay from a vat C2 are mixed with purified liquid in a crusher C3 and the suspension formed is added to the liquid passing through an inlet channel A for distribution to precipitating vessels E, F, fitted with baffles. Slime is deposited in these vessels and the cleaner liquid passes through further basins G, H, I and is discharged at J. Subsequently, surface water is removed from the vessels E, F, G by a pump K and delivered to the channel A. The same pump delivers the slime from the vessels E, F to a basin B, whence it is removed by a bucket chain or scraper conveyer which delivers it to a base R heated by means of steam or hot water to a temperature of at least 42‹ C. Inert matter is added to the slime which is then passed to a rotary vacuum filter, kept at temperature of 42‹ C. by means of steam which is used to detach the solid matter from the filter. The solid matter may then be allowed to dry in the open air.

Title: Indicator mechanism for use with electric relays
Inventor: LEWIS HARRY STANLEY
IPC: H01H50/08
Filed: 1959-04-06
Abstract: 878,699. Electromagnetic relays; indicators for switches. CHAMBERLAIN & HOOKHAM Ltd. March 28, 1960 [April 6, 1959], No. 11538/59. Class 38 (5). [Also in Group XXXVIII] An indicator mechanism providing indication of first and second operation of a relay comprises two plates 18, 19 which overlie one another and are hinged for movement about a common-axis 20 on one side of a fixed plate 21, 22. In the set position two discs 25, 26 respectively coupled by extensions 23, 24 to the plates 18, 19 are retained by projecting pins 39, 40 thereon engaging a hooked catch 42 on a pivoted armature carrier 13. A second projecting pin 43 on the disc 26 engages a surface 44 of a lever 38 pivoted about axis 20 and having a parallel projecting pin 41. Each disc 25, 26 is connected to a pinion 27, 28 engaging a respective arcuate rack 29, 30. The latter form the ends of levers 31, 32 pivoted at 33 and independently spring loaded so as to urge the discs and plates anticlockwise (Fig. 1). When the relay is actuated the catch 42 moves downward, releasing pins 39, 40 and engaging the pin 41 with the result that disc 25 and plate 18 are released to move through 180 degrees revealing the two faces of plates 18, 19 which were previously in engagement, plate 19 being retained by the engagment of pin 43 on surface 44. When the relay is de-energized the catch 42 re-engages pin 40 and releases pin 41 so that the lever 38, biased by a weight 45, or a spring, is turned and disengages surface 44 from the pin 43. Release of the pin 40 due to a second relay operation allows the disc 26 and plate 19 to be rotated by its biased lever 32 to the Fig. 5 position to overlie the plate 18 in the upper position and the pin 43 engages a surface 46 on the carrier 13 to retain it in the energized position. The indicator and relay is reset by actuation of a finger-piece 36 on the lever 31 which also has an extension 37 for engagement with the lever 32. In addition to the changeover contacts 15 . . . 17, the relay may be provided with contact devices (not shown) actuated by cams 47 coupled to the respective plates 18, 19 to give remote indication of operation.

Filed: 1919-05-09
Abstract: 149,727. Henderson, J. B. May 9, 1919. Gyroscopic apparatus.- In order to reduce the friction in the suspension of a gyroscope intended, for example, to be used as a compass on aircraft, the horizontal trunnion axis comprises two coaxial bearings one of which is a knifeedge, and the vertical trunnion axis also comprises two coaxial bearings, the intermediate elements of the bearings being oscillated by power taken from the gyro rotor. As shown in Fig. 1, the vertical gimbal ring 2 is pivoted in the horizontal ring 1, the following element 5 being pivoted on trunnions 6, 7 in the ring 2. The sensitive element is mounted in a ring 11 bearing in trunnions 12, 13 and suspended on the filar 20 fixed to the torsion head 21 carried by the stem of the trunnion 6. Pivoted on horizontal ball-bearing trunnions 15, 16 in the ring 11 is a ring 14; the trunnions 15, 16 also carry seatings supporting the knifeedges 18, 19 carried by the gyro casing 17. The ring 14 is controlled relatively to the casing 17 preferably by an air jet from the nozzle 28 passing through a shoot 29 carried by the ring 14, the shoot being divided by a twisted diaphragm. The eddies in the air jet maintain the ring 14 in a state of oscillation. The ring 5 is similarly controlled by a jet from the nozzle 31 passing through a hole in the trunnion 16 and entering a shoot 32. Gravitational control is imparted to the gyro by a level 33, as described in Specification 166,570. The level is pivoted at 37, 38 to the casing 17 and may be controlled by an air jet from the nozzle 50 passing into a shoot 51 carried by the bracket 39. The rings 2, 5, 11 can turn somersaults around the gyro when the aeroplane loops or rolls. To increase the amplitude of oscillation of the ring 5 or 14, the shoots 29, 32 may be replaced by pivoted vanes 65, Fig. 3, having fins 69 at one end, the motion of the vanes being limited by stops 70, 71.

In a nuclear fusion device, an ionisable gas is injected into a plasma confinement chamber which contains both A.C. and D.C. magnetic fields. The D.C. fields are formed by both external and internal solenoids while the A.C. fields are produced by a waveguide antenna injector aligned with the chamber longitudinal axis and having cooled windows. The internal solenoids form a radial magnetic field. Highfrequency energy is transferred to the plasma through the waveguides and circular polarization antenna and ionization is effected by the cyclotron motion of the electrons. The radial velocity of the ions is converted to axial velocity by the axial magnetic field. The plasma is confined by the magnetic fields and the charged particles oscillate between the magnetic mirrors at the ends of the confinement zone to effect fusion.
