L., 5, Radford Road, all in Coventry. Nov. 15, 1934, No. 32849. [Classes 79 (iii) and 136 (iii)] The petrol tank is secured on a motor-cycle by a flexible metal strap 10, permanently connected at one end 9 to a part such as the cycle head 5 and at the other end adjustably and detachably connected to another part such as the top-rail 3, the strap embracing the tank longitudinally, preferably with an aperture therein to clear the filling spout 16. Attached to the base of the tank may be an inverted channel bar 2 adapted to seat on the top rail, preferably with a layer of felt or rubber interposed. A similar cushioning layer 13 may be provided between the strap and the tank. At the end 9, the strap is connected by a hinge pin to a lug 6 on the cycle head 5 conforming to the shape of the tank with all extension 8 for attachment of the top rail 3 which comprises a pair of spaced angle bars. At the other end, a bolt 11 integral with a cross-pin 17 passes between the angle bars and is secured by a wing-nut 12.

Abstract: 307,326. Graham Amplion, Ltd., and' Freedman, P. Dec. 5, 1927. Vacuum tubes.-An equipotential cathode is heated wholly or partly by positive-ion bombardment from an auxiliary electrode and is so shaped and arranged as to form an electrostatic enclosure for the auxiliarv electrode and the discharge region between it and the cathode in respect to the other electrode or electrodes. The valve mav be highly exhausted, the cathode being in the form of a filament or other heater coated with a material capable of emitting positive ions, such as a composition prepared by fusion of a mixture of magnetite with 1 per cent of aluminium oxide and 0.5 per cent of caesium incorporated by the addition of caesium nitrate; or the valve may contain gas at low pressure such as helium or neon, or the vapour of an alkali metal such as caesium or rubidium. The cathode is either maintained at a negative potential with respect to the auxiliary electrode so as to be heated by positive ions, or an alternating potential may be applied to the electrodes so that the cathode is bombarded by positive ions and electrons and also possibly by heavy negative ions. As shown in Fig. 3, the auxiliary electrode consists of a cylinder 2<a> with a central stem 5a as described in Specification 291,531, the cylinder being covered with the composition already referred to. The cathode consists of a cylinder 1 closed at the top. In a modification the auxiliary electrode consists of a tungsten rod. In another arrangement the auxiliary electrode consists of the outer plate of a tubular condenser having a dielectric layer and an inner plate as described in Specification 307,325.

Filed: 1976-08-06
Abstract: 1525350 Pressure indicators PALL CORP 6 Aug 1976 [8 Aug 1975] 32926/76 Heading G1L A magnetic pressure indicator includes a sampling port in its housing. The indicator comprises a first magnet 1 in a piston 5 biased upwards by a spring 7. Pressure e.g. from opposite sides of a filter is applied to the top and bottom faces of the piston via ports 12, 13. Whilst the pressure difference is below a predetermined value the magnet 1 holds a second magnet 2 against a spring 82. When the pressure difference rises piston 5 is forced down carrying magnet 1 away from magnet 2 allowing spring 82 to force magnet 2 up to the position shown dotted. A wall 3 which may be a magnet or of magnetizable material isolates the indicating magnet assembly from the fluid. A filter 16 surrounds the inlet from port 12; a bi-metal strip 60 prevents the indicator operating at low temperatures. The polarity of the magnets may be reversed. The sampling port includes a ball 35 which can be moved inwardly by a spring-loaded pin 43 by a member 30 (shown dotted). Fluid emerges through passage 36, slot 42 in the pin head and a channel in the member 30.

Abstract: 875,304. Filters. COMPAGNIE DE CONSTRUCTION DE GROS MATERIEL ELECTRO-MECANIQUE. Sept. 29, 1959 [Oct. 24, 1958 ; July 8, 1959], No. 33018/59. Class 46. A filter having an inlet 2 and outlet 10 has a fixed cylindrical surface within which is mounted a pump comprising two bores 11, 21, movable about an axis coinciding with that of the filter surface in such a manner that they can only turn in one and the same direction. The bore 11 is moved towards the bore 21 to force the liquid between the bores through the filter surface, against the normal flow, to clean it. The bore 21 is then moved away from the bore 11 by a predetermined amount so that the cycle may be repeated on the adjacent section of the filter surface. The bore 11 is  connected to the shaft 12 which is prevented from turning anticlockwise by the ratchet arrangement 18, 19, and the bore 21 is mounted between the plates 22 and 23 which are also prevented from turning anticlockwise by the ratchet arrangement 24, 25. A spring 27 maintaining the bores apart by a predetermined amount in the normal position. Rotation of the bores is effected manually through the levers 20 and 26. In the embodiment shown in Figs. 4 and 5, the movement of the bores is effected by the rotor body 29 which is keyed to the shaft 12. A flap 31, integral with the plate 22 and bore 21, is moved in a chamber 30 by filtrate under pressure entering either through the duct 32 or 33, the cock 35 and port 38. The plate 22 carries an arm 43 connected by compression spring 44 to an eccentric nipple 45 of the cock 35 which controls the position of the cock owing to the movement of the bore 21 relative to the body 29. In the embodiment shown in Figs. 6 and 8, a chamber 51 is formed by the cup member 50.and plate 22 which is divided into two chambers 51a, 516, by flap 31, attached to the plate 22 and bore 21, and the flap 52, attached to the shaft 12 and bore 11. The flaps 31, 52 are moved by pressure charges in the chambers old, 51b by alternatively connecting each chamber to the filter interior and to the drain 41, in such a manner that the approach of the bores 11 and 21 is sudden and the moving apart is comparatively slow.

The cutter shaft 3 is driven, and is connected through a reversing clutch 12 to the shaft 14 carrying a pinion 16 which can be interchanged with larger or smaller pinions, and drives, through an intermediate pinion 17 which is vertically adjustable. a wheel 72 on the spindle 71 of the lower feed roller 7. The upper feed roller 6 is carried bv a bridle 26 which slides in slots 25, Fig. 3, in the cheek-plates 19, and engages an arm 55 connected to an arcuate cover plate 49 sliding in guides 50, which is thus caused to follow the movement of the bridle 26 and close the slots 25. The roller 6 is pressed down by springs 30 abutting against an adjustable bar 33 and is maintained horizontal by links 47 attached to the bearings 27 and connected through levers 44, pivoted at 43, and a link 45. The upper roller is driven from the lower feed-roller by gearing having long teeth which remain in engagement throughout travel of the adjustable roller. The upper feed roller is provided with a comb-bar attached to a frame pivoted to the bridle 26 and adjusted by nuts 99, 100 on rods 97. A reversible mouth plate 101 which coacts with the cutter blades rests upon the bar 95 and is adjusted by means of a rod 103 and is clamped by a screw 109.
