Title: Determining an in-cylinder pressure curve representative of the evolution of the pressure within a cylinder
Inventor: TUGNOLO MANUEL
IPC: F02D35/02
Filed: 2009-10-16
Abstract: An in-cylinder pressure curve representative of the evolution of the pressure within a cylinder of a multi-cylinder internal combustion engine is determined by setting a timeframe in which the engine is functioning such that the pressure in at least two cylinders is sampled at consecutive time periods within the timeframe in order to acquire partial in cylinder pressure curves for each cylinder. The partial in cylinder pressure curves are used to reconstruct a whole in cylinder pressure curve. Each sampling period may be adjusted separately from each other on the base of one or more engine operating parameters, the adjustment may be the period width, opening or closing and the parameters may be the engine speed or engine load. The partial in cylinder pressure curves may be representative of different stages of an engine cycle. The sampling periods may be chosen such that the at least two partial in cylinder pressue curves comprise of an overlapping portion and a non overlapping portion. The method may be cyclically repeatable during the engine functioning. A computer program may be used to carry a computer code to perform this method.

Title: Improvements in and relating to booster engines or motors for locomotives
IPC: B61C15/02
Filed: 1926-04-17
Abstract: 274,204. Stenning, H. A. April 17, 1926. Hand gear; automatic gear; catches, arrangement and application of, and dis. connectible gearing.-In a steam - driven locomotive booster engine, the operation is controlled by a differential piston valve C which is moved in one direction by steam pressure to throw the engine out of action, and is operated through lever mechanism e, E by a cam D on the reversing lever when in positions between full forward gear and 50 per cent cut-off to operate the engine. A small quantity of steam is supplied to the engine to warm and run it slowly until the driving-gear is in operation when the main booster supply is opened. The cam D. can be turned out of the path of the arm e by means of a handle d. The casing of valve C is connected at a to a steam valve A, at 5 to exhaust, has ports F, G controlled by the valve, and has a branch J leading to the bottom of the gearentraining piston 0. The upper end of the casing of piston 0 is connected to the exhaust at V, and has ports T, U leading to pipes S, W connected respectively to pipe J and an auxiliary spring- pressed piston X which controls the main booster valve Y. The piston 0, Fig. 3, has bronze packing-rings of cup-leather type 7, 7<a>, 7b. The upper rings are spaced and arranged around a reduced part 19, and constitute a valve to control connections T, U and U, V. The rocking- arms Q<2> which carry the gear wheel Q which connects the booster shaft and locomotive axle is connected to the piston 0 by means of a crossbar 15 and have extensions q engaging transverse pins in spring-mounted rods. A hand-operated valve is arranged in front of the valve Y. The pipe J has two branches, one H connected to a fluid-actuated preliminary-supply throttle valve m<1>, the other L contains a ball valve K and is connected to pipe W. In working, when valve C is depressed by the cam D, ports F', G are connected and steam passes to the valve M by pipe H thereby warming and starting slowly the booster engine, and steam passes' to act on the piston 0. The arrangement of the packing on the piston 0 and the ports T, U is such that steam cannot pass to the engine by valve Y until the gears are in mesh. When the gears' engage and the piston 0 is raised, steam passes by branch S, parts T, U, and pipe W to piston X, thereby opening valve Y to run the booster normally. The engine is stopped by turning the cam or moving the lever 6. Steam then shuts valve C and the bottom of the cylinder of piston 0 is put to exhaust, the piston 0 descends, and pipe W is put to exhaust and the valve Y closed. The valve K which was raised against its seat during running opens and accelerates the release of pressure in pipe W. The steam pipe is connected to a drain pipe Z containing a ball valve 2, and also a valve 3 which controls an auxiliary spring-pressed plunger which automatically opens and closes the cylinder drains. The booster mav drive a rear, forward, or tender axle.

Abstract: 746,766. Supervising centrifugal separation by radio-activity. KODAK, Ltd. April 14, 1954 [April 14, 1953], No. 10163/53. Class 40 (3). The thickness of deposited material in a centrifugal separator is determined by means of a beam of gamma rays. As shown, denser material to be separated is deposited as a layer 9 on the wall of a rotating drum 1. This drum is surrounded by a housing 2 having an outer lid 3 and an inner lid 5. The inner lid carries a lead block into which is screwed a plug carrying a pin 14 on the end of which is a gamma ray source such as radium or cobalt. A small hole 15 provides a narrow beam of radiation so that cut off of the beam by increasing thickness of deposit is relatively sudden. Below the drum is a second lead block 16 carrying a Geiger detector 11. A hole 4 in the block allows the gamma rays to reach the tube. This hole may be elongated as shown in Fig. 3 to increase the sensitivity of the detector to dispersed radiation. A phosphor screen and photocell may be used instead of the photo-cell. A centrally located radiation source may be used to direct gamma rays radially and horizontally to a detector outside the drum or both source and detector may be situated outside the drum so that the beam passes twice through the wall of the drum.
