Abstract: 657,049. Aerials. RADIO-INDUSTRIE. May 29, 1947, No. 14318. Convention date, May 31, 1946. [Class 40 (vii)] In a scanning directional antenna system of the kind in which radiation is fed into a parabolic or other suitable reflector the feed member is a wave-guide having one side wall provided with a plurality of slots arranged to give directional transmission and having means for continuously moving it, or at least said side wall thereof, in a direction parallel to the plane of said side wall to cause continuous scanning. In the embodiment of Fig. 1 an endless screening band 3 having horizontally stacked slots is adapted to run on drums 3a such that the slots pass continuously across the open face of the wave-guide 2, which is shown above its actual level for clarity but would in fact be directly behind band 3. In another embodiment (Fig. 2, not shown), a slotted plate is reciprocated in front of the wave-guide opening by means of cams and causes scanning in alternately opposed directions. A similar scan is provided by the embodiment of Fig. 3 (not shown), wherein the slotted wall is integral with the wave-guide and the whole is reciprocated by a cam and return spring. Conical scanning is provided by reciprocating such a slotted waveguide in both the direction of its axis and perpendicular thereto by means of cranks, as in Fig. 4 (not shown). The Specification as open to inspection under Sect. 91 comprises also a reflector designed to make the reflected beam substantially flat in a plane transverse to the feeding wave-guide (Fig. 1 (Cancelled), not shown). Its surface is generated by a parabola P1 displaced to remain always parallel to the plane of the wave-guide and so that its vertex lies on another parabola P2 fixed in space with its plane perpendicular to the axis of the wave-guide. The focal length of parabola P2 is greater than that of P1 and the wave-guide intersects the axis of the reflector at the focus of parabola P1. Alternative means of producing scanning are also disclosed wherein the wave-guide is equipped with dielectric radiating elements and the beam directivity is controlled by means of rods on the opposite face of the wave-guide having their respective depths of engagement varied by cams as in Fig. 6 (Cancelled) (not shown) ; or the dielectric elements may be pivotally mounted and oscillated simultaneously by a coupling rod as in Fig. 7 (Cancelled) (not shown). This subject-matter does not appear in the Specification as accepted.

Patent GB-270108-A (GB)
Title: Improvements in and connected with pulp thickeners or filters
IPC: B01D35/12
Filed: 1926-06-11
Abstract: 270,108. Haddan, R., (Oliver Continuous Filter Co.). June 11, 1926. Filters having sheet filtering-materials. - Tubular filter elements 1, suspended in a tank 2 containing material to be filtered and kept clear by the periodic introduction of air or gas under pressure, have filtering material 16 covering the whole length of the tubes and inner depending tubes 18 which secure that a quantity of liquid within the tubes is driven outwards before the gas under pressure passes out. The elements are connected in sets by pipes 23 to the casing 24 of a rotary valve which connects each set successively to vacuum and a source of gas under pressure. This valve and the pipe 2<1>, through which material is supplied to the tank are preferably placed below the level of the liquid in the tank. The filter fabric 16 is retained in position by wire or other winding. The bottom of the tank slopes towards a conveyer with inclined blades 5 coacting with breaker blades 6 fixed to the tank and pushing settled matter to an outlet 7. Froth or scum on the surface is moved to a launder 660 by rakes 650 which are mounted on endless chains. The rotary valve is as described in Specification 270,616. The casing 24, Fig. 5. has apertures for the connection of the pipes 23, of a pipe 27 leading to a vacuum and of a pipe 26 from the source of pressure. The pipes 27, 26 connect respectively with circular passages 34, 33 in the casing, and each of the pipes 23 is connected to the passage 33 through a plug valve 30. All the pipes 23 except one are in communication with the passage 34 through a port 36 on the plug 35, but a longitudinal projection 350 on the plug closes the end of each of the pipes 23 successively as it rotates. As it does so a pin 35<1> on the plug contacts with the handle 31 of the corresponding valve 30 and gas under pressure is delivered from the passage 33 to the pipe 23 from which the vacuum has been shut off. The apparatus is applicable for thickening pulp. It may also be applied for filtering such liquids as gasoline or alcohol in which case the vapour of the liquid under treatment is used for the reverse pressure.

Abstract: 878,994. Impregnating for electric insulation. HUNTING MHOGLAS Ltd. April 26, 1960 [May 1, 1959], No. 15007/59. Addition to 747,257. Class 140. [Also in Group XI] In the method disclosed in the parent Specification of making a flexible resistance by coating a non-combustible previously cleaned fabric (such as woven threads of glass or silica) with a liquid dispersion of colloidal graphite, heating to remove liquid or allowing to dry, subsequently heating to 500‹ C., cooling, and finally coating with a protective varnish, the protective varnish is a silicone resin rendered highly penetrating by dilution or by dilution accompanied by heat and used in that condition to effect the coating: As the initial varnish coatings cause an increase in the electrical resistance of the element successive coatings are applied until the resistance becomes constant. A normal silicone resin of 60% solids is diluted in xylene to 0.1% solids or less depending on the viscosity of the resin and applied by dipping, the solvent then being evaporated off before further coatings are applied. A final coat of less dilute resin may be applied, the whole being subjected to the normal drying and curing process. In another form a resin of 10-20% solids is used. At least the final coatings and probably one or more intermediate coatings may comprise a silicone rubber applied as a paste, a dilution or a rubber stock. The Provisional Specification states that a silicone resin diluted to about 10% solids, to which is added a low boiling point wetting agent such as sorbitan polyoxyethylene laurate or oleate, may also be used as the varnish. The first coat is applied and heated sufficiently to remove the wetting agent and a second coat without wetting agent is applied.

Abstract: 1,201,283. Tubular electrodes. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 28 March, 1968 [31 March, 1967], No. 15067/68. Heading H1B. A tubular electrode for an alkaline storage battery comprises two half-shells each being made of perforated metal and comprising a recessed part with a surrounding flat edge and being filled with a compressed active material, said half-shells being secured by their edges to opposite sides of a metal band. The half-shells may be made of nickel-plated steel. The flat edge may not be perforated, the perforations in the recessed part being about 0À7 mm. apart and not more than 0À2 mm. in diameter. If the electrode is a positive one the active material may be nickel hydroxide containing graphite or nickel or cobalt powder. Cadmium hydroxide may be the negative active material. The metal band may also be perforated. The electrode may be made by making a continuous groove in a strip of perforated metal, placing active material at intervals along the groove, compressing the active material, placing two such strips on either side of a metal band, joining them to the band and punching and cutting the assembly between the portions of active material. Alternatively, in the first step of this process instead of making a continuous groove a series of recesses may be formed. Each half-shell may contain metal current collectors in contact with its inner wall. These may be nickel-plated perforated strip, screen, or wire. In a particular embodiment, Fig. 2, the recessed metal strip, 1a, forming each half-shell is filled with alternate portions of active material, 3, and metal strips 4. To make a multiple electrode (Fig. 4, not shown) the electrodes may be formed with the central band longer than the half shells, the electrodes being arranged parallel to each other and the protruding ends of their bands being joined to metal supports. The electrodes may be initially of circular cross-section, but may then be deformed to hexagonal crosssection so that they may be used in staggered relation in the cell, Fig. 6.
