Patent GB-734293-A (GB)
Abstract: 734,293. Supply systems for space discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 12, 1952 [Sept. 15, 1951], No. 22951/52. Class 38 (4). In a circuit in which a first gas- or vapourfilled electric discharge tube 1 is connected in series with a second such tube 10 and both tubes are in series with a ballast inductance 4, the second tube 10 being shunted by a ballast reactance which is capacitive at the working frequency and comprises a capacitance 2 in series with an inductance 3, the tubes are of a kind which can be ignited without a shortcircuiting switch at double their normal operating voltage, and the impedance of the capacitive reactance 2, 3 is not greatly different from, and preferably about 1.5 times as great as, the impedance during operation of the shunted tube 10. Tubes of the said kind may each have an internal auxiliary strip electrode 9, 13 or may have their main electrodes 7, 8, 11, 12 heated by a transformer. Electrode 11 of tube 10 may be connected to tap 15 or to tap 16 of inductances 3 or 4 instead of to point 14 between such inductances, and for facilitating ignition either tube 1 may be shunted by an inductor 17 or tube 1 and capacitor 2 may be shunted by a series combination of a capacitor 18 and a resistor 19. The source voltage may be transformed to that value required at the circuit input terminals 5, 6. The circuit is designed to reduce flicker and to yield an overall P.F. near to unity. Circuit dimensions are given in the Specification. Specifications 565,843 and 734,289 are referred to.
Patent GB-764212-A (GB)
Abstract: 764,212. Hatch covers. G. M. E. CORPORATION. Jan. 14, 1955 [Jan. 19, 1954], No. 1229/55. Class 113. In a hatch cover comprising a pair, or a series of pairs, of panels or covers A1-A2, B1-B2 pivotally connected at 24, and a reaction member 25, a hydraulic unit 31, 32 is mounted in each panel and connected to the member 25 to rotate the panels about their pivotal mount whereby the initial movement of one panel precedes that of the other. The panel A1 is hinged to the deck 11 at 16, and the other panels have rollers 16<SP>1</SP> which ride along rails 13 along each side of the hatchway. The hydraulic unit 31 has a single acting plunger 35 with a cross sectional area greater than that of the piston 43 of the double acting unit 32. The units are pivoted at 33 to a beam 34 of the panel and have ports 42, 45, 46 connected by pipe lines 69, 71 to a hydraulic supply system controlled by a selector valve 64. When the panels are in the closed position and pressure fluid is supplied from line to ports 42 and 46, due to its greater area plunger 35 will move to the end of its stroke thereby rotating the panels until they make an angle of 90 degrees with each other. The piston 43 then moves to complete the rotation of the panels, i.e. until they are both raised to a vertical position. In the case of the series of pairs of panels, e.g. as in Fig. 5, due to the fact that the unit 31 of panel Al has to drag the panels B1, B2 toward the hinge 16, the unit 31 of panel B1 is less heavily loaded and would therefore operate to raise the panels B1, B2 before movement of the panels A1, A2 begins. Since the torque acting to rotate each panel depends not only on the effective areas of the plunger or piston but also upon the leverage of the force applied, the torque required may be obtained not only by choosing a suitable area for the plunger or piston but also by choosing a reaction member of such a shape to give the required line of action of the force applied thereto and hence the required leverage, which leverage D<SP>1</SP>, Fig. 6, may be different for the force (X) applied by one unit from that for the leverage (D<SP>2</SP>) of the force (Y) applied by the opposite unit.
Patent GB-772490-A (GB)
Abstract: 772,490. Turning-gear; starting. PROCOMBUR SOC. POUR LE TRAITEMENT DES COMBUSTIBLES. March 22, 1954 [March 25, 1953], No. 8274/54. Class 7 (5). [Also in Group XXVIII] In a method of facilitating the starting of an engine wherein globules or particles of a starting fluid are introduced into the engine along with the main charge to facilitate combustion of the latter, the globules are obtained by atomization of droplets of the starting fluid in liquid form entrained in air by an ejector effect. A reservoir 23, Fig. 3, opens through an outlet 26 into a cavity 27 that houses a filter 29 and communicates with a well 33 that opens via a calibrated orifice 34 into a conduit 3 which is connected to the engine induction system. A conduit 6 which is joined to a single or double-acting manually-operable pump 194 (see also Group XXVIII) opens at the other end into the reservoir 23 above the level of liquid therein and communicates with the conduit 3 through another calibrated orifice 36. The reservoir and pump may be mounted on a vehicle dash-panel. In a modification, an electric starter 50, Fig. 6, with an axially movable pinion 53 is coupled to a vane or other type of rotary pump 58 which draws in air through a filter 59 and supplies it via the conduit 6 to the upper part of a reservoir 5, Fig. 7, which also communicates with the engine by the conduit 3 incorporating a calibrated orifice 17. Downstream of the latter is a calibrated port 16 which leads to the base of the reservoir 5 by a pipe 15. Conduit 3 supplies two parallel connected sprayers 61, 62, Fig. 6, each opening into an intake manifold 66, 67 provided with a filter 63, 64 catering for one engine cylinder or a group of cylinders. In another embodiment each side of the pump is connected through a ball valve with a feeder pipe containing starting liquid. Sufficient starting liquid for one or more starts is introduced into the reservoir, for example from 'a flangible receptacle that is pierced by a punch, and the pump 194, Fig. 3, is actuated ; part of the air from the latter enters into the top of the reservoir 23 and the remainder traverses the orifice 36 and flows into the conduit 3. The pressure drop caused by the orifice 36 forces the liquid in the well 33 to rise above the normal level h-h and issue from the other orifice 34 into the conduit 3 in a finely divided state where it is entrained by the air and delivered to a sprayer in the engine intake. The engine starter, not shown, is then operated. Before entering the induction manifold the entrained fuel may be further divided by flowing through a restricted opening. The introduction of starting fuel may be continued until a stable idling condition of the engine results. In the modification of Figs. 6 and 7 the operation is similar but the starter and air pump are conjointly actuated. The apparatus may be cleaned by continuing to supply compressed air after the charge of starting fuel has been admitted to the engine.
