Abstract: 991,068. Differential pressure indicator. DONALDSON CO. Inc. Sept. 30, 1963 [June 13, 1963], No. 38468/63. Heading G1L. A gauge for indicating the alteration in suction in an air intake manifold 2 is connected by a tubular connector 4 to the manifold 4 between an air filter 1 and the carburetter 3 and when the filter 1 is free of dirt a spring 11 depresses a bellows 17 upwardly Fig. 4, but when the filter 1 is dirty the pressure in a primary chamber 7 decreases and the higher atmospheric pressure passes through apertures 32, 24 to deflect a disc valve element 21 away from a seating 23 to allow the air to pass through apertures 25 to expand the bellows 17 to the position shown in Fig. 5 in which position a coloured wall 14 of a position 12 is visible through a transparent wall 8 indicating that the filter 1 requires renewal or clearing. After renewal or clearing of the filter 1 the air is exhausted from the bellows 17 by depressing a button 30 to open valve 21. In an alternative arrangement, Figs. 10 and 11 (not shown), the gauge is connected before and after a filter.

Abstract: 1519321 Ignition plugs; ignition systems MASSACHUSETTS INSTITUTE OF TECHNOLOGY 23 Sept 1975 [23 Sept 1974] 38894/75 Heading F1B Apparatus for igniting a fuel/air mixture comprises a corona electrode 0 for charging fuel droplets in the fuel air mixture and collecting electrode means, 1, 2, 3, 4 for concentrating the fuel droplets in a collecting mode and for igniting the fuel droplets in an ignition mode, the geometry of the collecting electrode means being such that an enriched region of fuel air mixture is provided that is extended in space and provides a large ignition zone. As shown there are gaps 10, 11 and 12 between the electrodes. The electrodes 2 and 3 are "floating" electrodes capacitively coupled to earth G. In a collecting mode of operation a switch S 1  (Fig. 2) is closed by a controller 13 upon the contact point 6 to thereby create a potential difference between the central electrode O and the electrodes 1 to 4. The switch S 1  is then moved under the influence of the controller 13 over to contact 7 to establish a sparking mode of operation. In the sparking mode of operation an arc will travel across the gap 10 then the gap 11 and then the gap 12. A high voltage pulse is supplied from a high voltage source which may be a capacitive ignition system. Modified forms of ignition plug are described.

The pistons of fuel injection pumps are double acting and are positively actuated on each stroke either by a surrounding radially acting rotary cam or by opposed axially acting rotary cams, both ends of the pistons being in cam engagement, and the spill point in each stroke is controlled by the angular position of the piston and can be altered during delivery. In the embodiment shown in Figs. 5, 6 the piston 46 is reciprocated in a carrier 47 by rods 54, 55 sliding in guides 56, 57 and engaging a three lobed cam surface 60. Fuel is drawn into the cylinder spaces through valves 50, 51 and delivered to oscillating distributing valves 65, 66 including spring loaded valves 71, 72, which deliver to outlets 67, 68. The distributers are oscillated by eccentric pegs 75, 76 which engage a cam track so shaped that the distributers are stationary during delivery. The position of the spillway 78 in relation to the mean position of the piston 46 is adjusted by means of an eccentric ring 80, the angular position of the piston being adjusted by a rack 25. Leakage grooves 83, 84 are provided in the guides 56, 57 and also grooves 85, 86 which are fed with pressure oil by a pump 88 having a pressure relief valve 93. A two-piston embodiment in which the pistons are actuated by opposed axially acting cams is described, and also a single radial piston embodiment ; in both embodiments the pistons, discharge directly to the outlets.

In an electrolytic capacitor of the wound or stacked type the anode consists of a plurality of individual electrodes 2 separated solely by surrounding material (not shown) or by strips 4 permeable to the electrolyte so that both sides of the individual electrodes are adequately wetted. The anodes 2 may consist of foils, e.g. of aluminium, tantalum, magnesium or niobium, formed with the usual dielectric oxide layer and roughened or perforated by mechanical or chemical means to increase their surface area. Alternatively, they may consist of sintered material or may be built up of thin parallel wires extending parallel to the longitudinal axis of the capacitor. The strips 4 may consist of thin absorbent paper or be replaced by amorphous surface layers applied to the oxide layers of the anodes 2. The cathode may also consist of two foils 1 constructed similarly to the anode foils 2 and are separated therefrom by strips 3.

Abstract: 1485147 Valves ANCIENS ETS LEON GUILBERT & FILS 19 Sept 1974 [21 Sept 1973] 40967/74 Heading F2V A valve for controlling flow to a burner of a welding appliance has a closure member 25 on a stem 40 which is movable relative a seal 28 on a seating 30 by a lever 57 pivoted at 60 or a handwheel 52 having a screw-threaded connection with the stem. The handwheel 52 may be rotated to abut the shoulder 10A on the body to lock the closure member closed or may be rotated to cause a cup-shaped member 54 to abut the lever 57, which cannot reverse pivot due to abutment of the end 62 with the valve body lug 61. Thereafter further rotation moves the valve to a partially open or fully open position dependent on the amount of this latter rotation of the handwheel. When the valve is in a partially open condition depression of the lever moves the valve member towards the fully open position. The closure member has a frustoconical face provided with at least one groove 27 and is biased towards the seal 28 by a spring 33. The end 46 of the stem is received in an elongate slot 53 in the member 54 which is held between ears 55 on the lever 57 to prevent rotation of the stem when the handwheel is rotated. The stem is guided in bore 50 and by the corners of flats on the member 18 engaging the wall of chamber 17. The end of the spring 33 is supported by a cap 34 retained by a split ring 35 and sealed by an 0-ring 36.
