Abstract: 957,193. Securing screening elements. F. PARKER Ltd. Jan. 26, 1962 [Oct. 26, 1960], No. 36762/60. Heading B2H. [Also in Division E2] In a single or multi-deck screening apparatus at least one screening unit 4, Fig. 2, is adjustably secured to a frame 3 by a fastening element 8 in the form of a talon, at least one arm being secured to each talon to project outwardly through the frame, the arm or arms being rockable in fixed lugs 15, and held in an adjusted angular position by use of a wedge 17. Each screening unit 4, e.g. a wire mesh screen, is supported on fixed brackets 6 fitted with wear beading 7, and along its edges the element is bent to form a hook 11 protected by reinforcement 12. Each talon 8 is also bent at its lower end 10 to engage with the hook 11. Each arm 9 has an enlarged head 16 to engage the associated wedge 17, which has an inclined lower face engaging with an inclined upper face on a member 19 secured to a fixed bracket 14, Fig.3 (not shown). To tighten the unit 4 the head 16 may be raised by use of a tommy bar 23 inserted into a recess 22 and the wedge 17 is moved to prevent return movement of the head, the wedge being locked in position by a peg (not shown) fitted in one of several holes in the member 19. The wedge 17 also has an inclined side face 24 so that it can be used when turned on its side. The range of adjustment covered by the face 24 is complementary to that covered by the normal bottom face. In an alternative arrangement, Fig. 4, each head 16<SP>1</SP> is fitted with a pawl 25 engaging with a ratchet block 26 carried by the corresponding bracket 14. On raising the head 16<SP>1</SP> with a tommy bar the ratchet automatically locks the arm 9 against return movement. The apparatus on the screening elements may be vibrated, agitated, oscillated, or rotated.

Title: Improvements in or relating to photocathodes
Inventor: PHILLIPS JOHN LESLIE
IPC: H01J9/12
Filed: 1964-09-10
Abstract: In a method of manufacturing silver-oxide-alkali metal photocathodes, a silver substrate is subjected to cycles of electrolytic oxidation and reduction to increase the surface area of the silver substrate. In particular, a semi-cylindrical silver cathode, or a silver layer on a glass base, after cleaning in a solvent, then HNO3, and treating with hydrogen at 650 DEG C, is immersed in an electrolytic bath of potassium hydroxide solution together with a silver wire electrode. The C.D. is adjusted to 1 mA per sq. cm., and alternate oxidation and reduction is effected every 10 mins by reversing the polarity of the current through the electrolyzing circuit, Fig. 1 (not shown).  The cycle is repeated 12 times, and then coating is then washed and dried.

Title: Reinforcement for refractory linings
Inventor: SCOTT THOMAS MARSHALL
IPC: F27D1/14
Filed: 1966-08-19
Abstract: 1,138,239. Refractory linings. CAUSEWAY STEEL PRODUCTS Ltd. 21 Aug., 1967 [19 Aug., 1966], No. 37394/66. Heading F4B. A reinforcement and anchorage system for supporting monolithic refractory linings of a ceramic material such as silicon nitride, comprises a honeycomb structure of hollow hexagonal cells. The monolithic lining is cast, moulded or sprayed into and over the cells. In one embodiment, Fig. 1, alternate hexagonal units 23, 38 of slightly differing type are interconnected through connecting flanges 33, 34 and 37 by transverse bars 21, or pins 20, adjacent alternate units 45, 46 in further rows, being secured to the first row by pins 32. Shackles 22 on bars 21 secure the system to a metal framework (not shown). Apertures 30 in the side walls permit the passage of the monolithic refractory between the cells. In modifications, some of the hexagonal cells may be made up from two half hexagonal units such as 47 or 49 split in a direction parallel to bars 21, or from units such as 48 or 50 split in a direction perpendicular thereto. In all embodiments, the units may pivot about the bars 21 or pins 20 to take up a curved shape in one dimension. In further modifications (not shown) the honeycomb structure may be formed from identical units having single and double connecting flanges on opposed corners, or single connecting flanges symmetrically offset from a centre line on opposed corners, to lie adjacent each other on assembly. Alternatively, Fig. 7, hexagonal units 80, 95, 96, 97 may be used having connecting flanges extending from each corner, adjacent flanges such as 89, 98, 99 of three adjacent units being interconnected by bent plates 100 and pins 101 passing therethrough. Pivoting of the units about these pins again allows the structure to take up a curved shape in one dimension. The support bars pass through lugs (105, Fig. 8) formed on the walls, e.g. 81 of these units. Shackles 107 then secure, the bars to a metal frame (not shown). In further modifications, the structure may be made up from assemblies of units 110 having bosses at the extremities of all their connecting flanges, which bosses are connected by a pin to the bosses of the connecting flanges of two like adjacent units (Fig. 10, not shown), or from units 131, 132<SP>1</SP> having such a connecting boss in each corner, to which Y-shaped connecting pieces 144 are attached to complete the honeycomb structure. In a further modification (Fig. 12, not shown) single hexagonal units are connected together through adjacent walls by loose split pins to allow some curvature of the assembled structure. Alternatively the structure may be formed from an assembly of castellated ceramic strips (not shown). The side faces of the honeycomb structure may be flat or curved (Figs. 2-6, not shown) as desired.

Abstract: 1282465 Automatic analytical apparatus GREINER ELECTRONIC AG 25 July 1969 [18 Dec 1968] 37468/69 Heading B1X [Also in Division G3] Apparatus for sequentially carrying out chemical and/or physical analysis comprises at least one indexable conveyor 1 carrying vessels 11-15 to stations 10, 20, 30, 40, 50 where samples are treated and/or analysed by apparatus 21, 31, 41, 51 according to any combination of programmes I, II, III selected by control discs 60, 70, 80. Each control disc has related sets of control pins, e.g. 62, 72, 82, associated with particular vessels, in this case vessel 12. The pins are displaceable axially upon contact with energisable electromechanical relays 67, 77, 87 from a neutral position (see pin 63) to an activating position, (see pin 62). Relays 68, 78, 88 reset the pin 3. After a programme has been carried out, upon rotation of the control discs 60, 70, 80 on a/shaft 7 the activated pins contact control order receiving members, e.g. 24, 44 which then transmit these signals to their associated apparatus via leads 22, 32, 42, 52. Consideration of vessel 14, and its associated control pins 64, 74, 84 shows that at station 40 only the activated pins 64 and 84 will contact the members 44 and 56 and therefore vessel 14 will only be subjected to programmes I and III at this station. The conveyor 1 and shaft 7 are both indexed by a drive unit (not shown) via bevel gears and the drive unit is controlled by an impulse unit 6. Several conveyors may be used consecutively or alongside each other. The control pins may be associated with groups of vessels arranged transversely or longitudinally of the conveyor or conveyors.

Filed: 1958-11-21
Abstract: 895,226. Variable resistors. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 12, 1960 [Nov. 21, 1958], No. 37514/58. Class 37. The current path between terminals 2 and 3, Fig. 1, of a variable resistor of the meandered film type includes secondary excursions defined by cuts 8 arranged transversely of the primary excursions defined by cuts 4 and 7, which latter extend from respective opposite edges 5 and 6 of the resistive film. A wiper contact 9 can move along a track 10 along which the primary cuts are of increased width, 7A. In a second embodiment, Fig. 2, the film is of annular form, and the secondary cuts are omitted in the neighbourhood of the circular wiper track 10. In a third embodiment, Fig. 3, the film is of a metal oxide, and the wiper track 10 is again circular and intersects the cuts at right angles. The meandering film configuration may be produced by the partial removal of a film formed on an insulating base, by spraying the resistive material through a shaped mask, by the silk screen printing technique, or by the photographic technique disclosed in Specification 845,453. Templates, Figs. 4 and 5 (not shown), may be employed for producing the films. The parts of the resistive film upon which the wiper contact bears can be strengthened by the application of a metal layer, or the wiper may contact strips of strong and good conducting material extending from the points at which one primary excursion ends and another begins.

[Also in Group XXVI] A fuel system for a gas turbine aircraft engine including a positive-displacement fuel pump arranged to be driven by the engine and an air/fuel ratio control which comprises a main fuel flow control valve 15 operated in response to movement of an evacuated bellows 17, the bellows being housed in a chamber 18 which is subject to air delivered by an engine-driven compressor via a restrictor 24 and with air which is modified upstream of the restrictor by a leak to atmosphere controlled by a valve 11 variable in response to engine speed. The valve 15 is connected to a hinged rod 16 which is coupled to the evacuated bellows 17, the movement of the rod being limited by adjustable stops 25, 26. Air is fed into the chamber by the engine-driven compressor through pipes 20, 21, and restrictors 19, 24; the compressed air is also fed through a pipe 23 which, through a hinged leak-off valve 11 and pipe 22, communicates with atmosphere. The valve 11 is actuated by a Bourdon tube 5 mounted in a chamber 4 which is subject to pressure of fuel fed by an engine-driven pump, the interior of the tube being in communication with pressurized fuel downstream of a restrictor 2 via a tapping 6 leading from the main fuel flow line 1; the Bourdon tube may be replaced by other pressure-sensitive devices such as a piston or capsule. In operation, the fuel pressure, which is dependent upon engine speed, controls the leak-off valve 11 thereby regulating the pressure of the air in the chamber 18 which through the capsule 17 varies the opening of the fuel valve 15.

Title: Ore dressing
IPC: B03B1/00
Filed: 1962-10-05
Abstract: A magnetic ore is comminuted, deslimed, and concentrated by wet gravity sorting to produce a concentrate and a tailing, the tailing is subjected to wet magnetic separation, the concentrate thereby obtained being submitted to wet gravity sorting to produce a concentrate and a tailing rich in ore-gangue particles, and from the latter ore particles are liberated by attack with alkali or acid depending on whether the gangue is acidic or basic.  The ore may be a Minette paramagnetic ore, a mixed ore, e.g. colombo-tantalite, wolframite, or ilmenite. The ore is preferably ground to a particle size less than 0.5 mm. before it is wet-gravity-sorted, e.g. by hydrocycloning, decanting, sieving, tabling, and jigging.  The concentrate is suitable for smelting. The tailing is subjected to wet magnetic separation, preferably by passage past a single magnetic pole.  The magnetic ore concentrate may be agitated in water or ground to liberate ore particles from the ore-gangue particles, and wet-gravity-sorted, the concentrate containing, for example, 40% iron being suitable for smelting, and the tailing, containing for instance 25% iron and 30% silica, being subjected to chemical attack, e.g. heating at 200 DEG  C. with Na2Co3 solution of gangue is acidic or treatment with a mineral acid, e.g. H2SO4 if gangue is basic, to liberate ore particles, which are then deslimed and wet-gravity-sorted to yield a concentrate suitable for smelting and a tailing which may be recycled or discarded. The concentrate is agglomerated before smelting.
