Abstract: 352,006. Gas storage. WILLENBORG, W. J., 36, Clifton Terrace, New Jersey, U.S.A. Feb. 19, 1930, No. 5487. Convention date, Feb. 19, 1929. [Class 8(ii).] In an apparatus for generating and storing non-oxidizing gases such as combustion products from an internal-combustion machine, the non-oxidizing quality of the gases is determined by measuring the proportion of carbon dioxide, and the gases are diverted when this proportion falls below a certain limit. In the apparatus shown, the pistons 1g of an internal-combustion cylinder 1c and a pump cylinder 1d are connected to the same crank shaft 1e. The combustion products from the cylinder 1c pass through a scrubber lw to the pump cylinder 1d, from which they are expelled through a non-return valve 1r and a conduit 5a to a storage vessel 4g. The conduit 5a is provided with a valve 5c, normally opened by a spring 5y, leading to the atmosphere, and with a valve 5e, normally closed, leading to the storage vessel 4g. A branch 5h on the conduit 5a leads to a carbon dioxide indicator 5i of the Orsat type, operated by a motor 5j and provided with an indicating scale 5k on which moves a pointer 5n. When the pointer engages an adjustable contact 5m, current is supplied to a solenoid 5q, actuating a switch which closes the circuit 5s of solenoids 5t, 5u by which the valve 5c is closed and the valve 5e, leading to the storage vessel, is opened.

Title: Discharge lamp starting apparatus
IPC: H05B41/04
Filed: 1973-02-05
Abstract: 1411482 Starting systems for discharge lamps MATSUSHITA ELECTRIC WORKS Ltd and MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 5 Feb 1973 [7 Feb 1972] 5700/73 Heading H2H A starting system for a discharge lamp 1 comprises a pulse generating circuit including a transformer 5, a first capacitor 7, a first bidirectional diode thyristor 6 and a resistor 8, a diode 9, a second capacitor 10 and a second bidirectional diode thyristor 11. During the positive half cycles of the A.C. supply, the diode 9 is reverse biased and initially the thyristor 11 is conductive thereby charging the capacitor 10 until the charging current falls to a value insufficient to hold the thyristor 11 conductive. The capacitor 10 charges the capacitor 7 thereby switching on the thyristor 6. The capacitor 7 then discharges through the primary winding n 1  of the transformer 5 to generate a high voltage pulse in the secondary winding n 2  which momentarily switches on the thyristor 11 to supply the pulse to the lamp. Starting pulses at a frequency of 5 KHz are applied to the lamp until the charge on the capacitor 10 falls below the breakover voltage of the thyristor 6. During the negative half cycles of the A.C. supply, the diode 9 is forward biased and the residual charge on the capacitor 10 is superimposed on the instantaneous supply voltage to switch on the thyristor 11 thus enabling heating current to be supplied to the lamp cathodes 2, 2<SP>1</SP> via the secondary winding n 2 . Once the lamp has been ignited, the lamp voltage is less than the breakover voltage of the thyristor 11 which is therefore switched off.

Filed: 1927-03-02
Abstract: 293,365. Wade, H., (Naamlooze Vennootschap Philips' Gloeilaimpenfabrieken) March 2, 1927. Vacuum tubes.-In incandescent-cathode, gas-filled discharge tubes such as rectifiers operating with a low-tension arc, a resistance is connected in series with the path of the discharge and maintains the current substantially constant on changes of potential during operation of the tube. The resistance may be of iron or tungsten and the tube may be filled with rare gas such as argon. The foot 2 of the tube 1 may support the resistance 5, an anode 4 and a Wehnelt or other incandescent cathode 3. The resistance 5 is prevented from taking part in the discharge, and so disintegrating, by shaping the anode 4 as a right-angled screen as shown and by a glass screening tube 10. The cap of the tube has pins connected to the leads 6, 7 of the cathode and to the lead 8 which is connected to the resistance 5, the other end of the resistance being connected to the anode 4. A lead 9 to the anode is used only during manufacture of the tube when the electrodes are freed from occluded gases by a discharge heavier than normal.

Abstract: 709,340. Hydro-pneumatic shock-absorbers. BOULTON PAUL AIRCRAFT, Ltd. March 12, 1952 [March 13, 1951J, No. 5981/51. Class 108(3) A wheel-mounting unit for an aircraft t undercarriage comprises a combination of cantilever and articulated type units in which the normally-fixed member of one unit constitutes or carries the movable member of the other unit. In the construction 'shown in Fig. 2, the articulated unit comprises a cylinder 1 in which a piston 18 works. The piston rod 19 is linked to an intermediate point of an arm 15 which carries the aircraft wheel (not shown) at one end, and is fulcrummed at 16 to a bracket 14 rigid with the cylinder I. Liquid in the cylinder 1 is displaced by upward piston movement, through a valvecontrolled orifice 21 to displace a floating piston 22 against air pressure in the hollow piston rod. The cantilever unit is formed by the cylinder 1 and an outer cylinder 2. A head 4 on the cylinder 1 acts on liquid 8 and displaces it through an orifice n and a valve 13 to act on a floating piston 23 loaded by air pressure in an extension 60 of the cylinder 1. The valve 13 may be a valve of the kind described in Specification 707,970, [Group XXIX], and maintains a constant pressure across itself. In a modification, Fig. 1 (not shown), extension 60 is solid and carries a piston which has merely a dashpot action in the liquid 8. This piston may have an orifice, or controlled leakage may occur around its periphery. It also has a valve corresponding to the valve 13 of Fig. 2. In the construction shown in Fig. 3, the liquid space of both articulated and cantilever units are in communication tnrough orifices 110, and this liquid acts on a single floating piston 22. The leverage of the arm 15 and the ratio of areas of the pistons 4, 18 may be selected to cause closing of the articulated unit before the cantilever unit, or vice versa. Air may be charged into the hollow piston rod 19 through a valve which is slidable in a slot in the cylinder 1. A liquid-spring unit may be used instead of the hydro-pneumatic arrangements described.

Abstract: 687,579. Time-recorders. ASSOCIATED INDUSTRIAL CONSULTANTS, Ltd. June 12, 1951 [March 14, 1950], No. 6329/50. Class 106 (iv). A time recorder for use in taking time studies of the type including winding-off and take-up spools adapted respectively to receive a rolled paper band and to wind up such band into a roll and means to drive a driving roller intended to be in frictional or positive engagement with the band comprises a speed control roller interposed between the winding-off spool and the driving roller and adapted to be in frictional or positive engagement with the band and means to control the speed of rotation of the speed control roller. A record paper band shown in chain lines in Fig. 3 is drawn from a supply roll on a spool 23 mounted in arcuate slots 25 in side plates 10, passes over a table 11 which joins the side plates 10, and is engaged by rollers 18, 12 before passing on to a take-up spool 30 mounted in arcuate slots 32. The roller 12 is driven through gearing by a spring 16 tensioned by means of a key and the speed of rotation of the roller 18 is controlled by escapement mechanism 20. The spool 30 is driven by the roller 12 through a band, slipping allowing for the increasing diameter of the roll thereon and the spool 23 is braked by means of a band round a small roller 28 which engages a braking disc 29. Thus the paper traverses the table 11 at a constant speed and the device may be applied, e.g., to the time study of an operation by making a transverse mark with a pencil, using an edge of a window in an enclosing casing as a guide, at the beginning and end of an operation, thereafter reading the time off a predetermined time/length scale. Movement may be prevented by holding a finger on the paper band, or stop means acting on the roller 12 or shaft 15 may be provided to brake the drive. The engagement between the rollers 12, 18 and the record band may be through radially projecting pins on the rollers engaging holes along an edge of the band or it may be frictional, the rollers being formed of or covered with rubber or other friction material.
