Title: Improvements in and relating to evacuating apparatus
IPC: H01J9/385
Filed: 1947-02-07
Abstract: 646,026. Making electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 7, 1947, No. 3724. Convention date, Feb. 7, 1946. [Class 39 (ii)] [Also in Group XL(a)] An electric discharge lamp evacuating and filling apparatus comprises a plurality of conduits 47 having means e.g., a solenoid valve 52 and a pump (not shown) for maintaining a rough vacuum therein and a movable assembly e.g., an indexible turntable 1 including a fine vacuum pump 3, a support 22 for a lamp 27 connected to the pump inlet and a solenoid valve 14 between the pump 3 and the lamp 27 and complementary ports 43, 45 on the table 1 and a support 2 for connecting the higher pressure side of the pump 3 with a different one of the conduits 47 in each of a plurality of positions of the table 1. Sixteen stations are mounted on a peripheral flanges 5 and each comprises a pump 3, valve 14, support 22 and lamp 27 and at one of the stations viz., that shown, is provided a xenon, argon or hydrogen gas duct and a solenoid valve 54 energized by a mercury switch 56 responsive to pressure within the duct 47 and hence of the lamp 27, assuming valve 14 to be open. In operation closing of a manual switch 65 supplies power through slip rings 63, 64 and lines 66, 67 to the condenser pump heating elements and through a cam switch 69 to the solenoid of the switch 14. The switch 69 when closed corresponds to the open position of the valve 14 in all but the one position of the table 1 at which the lamps 27 are loaded. With a switch 72 in the L.H. position the valve 52 is open and the valve 54 closed to roughly evacuate the particular system in register. On moving the switch 72 to the R.H. position the valve 54 is opened when the pressure in the duct 47 is reduced enough to close the mercury switch 56 whereupon gas floods the pump 3 and the lamp 27; the consequent rise in pressure then effecting closure of the valve 54. As the table indexes to the next position the cam switch 69 opens to close the valve 14 thus shutting off the inlet side of the pump 3 whilst the lamp is being sealed, removed and a new one loaded. The pressure to which the lamp 27 is filled is varied by the setting of the switch 56.

Title: An arrangement for operating, more particularly for starting and running up, high-speed diesel engines
IPC: F02N19/04
Filed: 1956-02-15
Abstract: 823,390. Compression ignition engines; starting. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Feb. 15, 1956 [March 1, 1955], No. 4711/56. Classes 7(3) and 7(6) ln a compression ignition internal combustion engine, more particularly a high speed diesel engine, in which an ignition accelerator is introduced into the delivery path of the fuel, preferably during the starting and running up state, the ignition accelerator used is lubricating oil which is taken from the lubricating oil circuit of the engine and automatically added to the fuel inside the fuel injection pump, for instance in the suction chamber of this pump. As shown a feed pump 4 supplies the injection pump 2 by way of a filter 6. A hand pump 7 can draw either from a container 13 which contains an ignition accelerator or from the lubricating oil circuit. In the latter case the pump 7 is preferably connected to the oil sump of the engine as indicated at 14. The delivery of the pump is connected by the pipe 15 to the suction chamber of the pump 2. Alternatively the ignition accelerating lubricating oil can be injected by the pump 7 by way of branch pipes 17 or 18 selectively or in combination also into the fuel pipe 5 and/or into the filter 6. In order if required to be independent of the hand pump provision is further made to connect the lubricating oil circuit at a place where it is under pressure directly with the points 16, 5, 6. For this purpose pipe 15 is connected by a pipe 19 to the lubricating oil pressure circuit and a valve 21 is provided which may be actuated by hand and also automatically. The valve is made dependent on the temperature or the speed of the engine. With temperature control the valve opens automatically when the engine is cold. The valve may be controlled by electric or electromechanical means or thermostats. The hand pump and lubricating oil pressure circuit may be brought into use jointly or selectively separately. If ignition failures occur at high speeds the hand pump can be controlled by electric or electrooperation only in the region of high speeds of revolution and connect the suction chamber of the fuel pump with the lubricating oil circuit or the container 13. As ignition accelerators nitrates may be used. The pump plungers may open a connecting bore or groove for the passage of lubricating oil only when the plungers are moved into their position for injection of the starting charge. This lubricating oil may come from the lubricating oil circuit of the pump plunger.

Filed: 1974-02-01
Abstract: 1452864 Determining particle size distributions K LESCHONSKI 1 Feb 1974 [1 Feb 1973] 04845/74 Heading G1A [Also in Division G2] The size distribution of particles is determined by injecting them into a flowing carrier fluid (liquid or gas) so that the particles are distributed across the fluid-flow according to their size; the distribution is then found by measuring the absorption of radiation by the particles at different points across the flow. Figs. 1 and 2 show the carrier fluid 2 passing via flow straightening baffles 3 into a measuring zone 4, the particles being injected at 10. Small particles follow path 15 and large ones follow path 14 to form a distribution across the zone. A light source 5, lens 6, apertures 7 and detector 8 are pivoted about point 11 so as to scan across the zone along an arcuate path. The optical assembly is driven by motor 13; the inside of zone 4 is electrically conductive and is earthed to avoid static electricity. The scanning may be replaced by an elongate source; alternatively multiple sources and detectors may be reciprocated across the zone. The measurement may be effected in regions where there are no particles to obtain a measurement of the absorption due to the carrier fluid alone. Gamma rays may be used. The particle size measurement may be used for process control.
