Title: Compound power plants
Inventor: WOOD-COLLINS CHARLES ALLISTER
IPC: F02D23/00
Filed: 1954-09-17
Abstract: 778,302. Charge pumps; regulating. NAPIER & SON, Ltd., D. Sept. 6, 1955 [Sept. 17, 1954], No. 27052/54. Classes 7 (2) and 7 (6). [Also in Groups XXVI and XXIX] Charge air, supplied to a two-stroke diesel engine A Fig. 1, by axial flow and centrifugal compressors E, F in series and powered respectively by an exhaust-gas turbine D and the engine, is throttled under idling and/ or low load slow running conditions by a valve H, thus ensuring satisfactory compression ignition at such times. A blow-off valve S operating as described below is incorporated. The compressors E, F may be linked by a fluid coupling or an infinitely-variable gear as in Specification 663,296 to transmit power from the crankshaft or chankshafts of the engine A to the compressor E or vice versa. The valve H is operated by a piston J in a hydraulic cylinder J<SP>2</SP>. Under normal engine operating conditions a servo-motor piston M<SP>1</SP> acting on a boost control (not shown), such as a ratio-control of a variable-speed gear between the engine A and compressor E, is in a position such that a spring-loaded valve K<SP>2</SP> in a supply duct L, K to the cylinder J<SP>2</SP> is closed and a spring J<SP>3</SP> therefore holds the valve H open. Under idling or low load conditions, however, the piston M<SP>1</SP> moves upward sufficiently for its rod M<SP>2</SP> to open the valve K<SP>2</SP> and the consequent feed to the cylinder J closes the valve H to give the negative boost required by the setting of a spring P acting on the servo-motor valve N via a lever O and loaded by a cam Q on an engine control shaft also mounting a cam Q<SP>2</SP> controlling via tracks Q<SP>4</SP> and Q<SP>5</SP> (appropriate in the case of an aircraft engine to no-power flight and ground running conditions) the fulcrum of a lever R<SP>1</SP> in the normal fuel injection control mechanism. The boost pressure re-acts on the valve N via a diaphragm O<SP>1</SP> the atmospheric pressure on which is counter-balanced by that on an evacuated capsule O<SP>2</SP>. The blow-off valve S, Fig. 1, operates to prevent compressor surging under idling &c. conditions, the compressor delivery pressure acting via a duct X on a spring-loaded pilot piston V<SP>2</SP> to uncover ducts V<SP>3</SP> or V<SP>4</SP> as this pressure falls or rises and so vent or pressurize the space below a main valve piston V and correspondingly open or close the valve member U<SP>2</SP>.

Title: Dividing mechanism
IPC: B23F23/08
Filed: 1971-04-19
Abstract: 1285317 Grinding KAPP & CO WERKZEUGMASCHINENFABRIK 19 April 1971 [16 July 1970] 27208/71 Heading B3D A dividing mechanism for a linear dividing table 1, for use in a machine for grinding a tooth rack 2, comprises first drive means for producing fine movement of the table, second drive means for producing coarse movement of the table, a common drive system for transmitting drive from the first and second drive means to the table, and control means for the first and second drive means to actuate each drive means to move the table by a predetermined distance. The table 1 is supported for movement on a bed (3, Fig. 4, not shown) by rollers (4, 5) and carries a rack 6 engaged by a positioning pinion 7 mounted on a shaft 8 having a worm wheel 9 engaged by a worm 10 on an output shaft 31 of a summation gear 30. The latter is connected to the spindle 22 of the coarse drive and, by reduction gearing 20 to the spindle 12 of the fine drive. The spindle 12 carries a dividing disc 11 and an impulsing disc 16 and is connected by a differential gear 13 to a high speed motor 14 and a low speed motor 15, the motors being arranged so that where one is driving the other is braked. The spindle 22, likewise, carries a dividing disc 21, impulsing dsic 26 and is connected by differential gear 23 to a high speed motor 24 and low speed motor 25, one of which is braked while the other is driven. Each dividing disc 11, 21 has notches 11a, 21a which are engaged by a roller 19, 29 on a lever 18, 28 which can be moved against a spring 34 by fluid pressure supplied to a cylinder 33 to disengage the roller from the disc. Each impulsing disc 16, 26 has markings 16a, 26a which are detected by a pulse signaller 17, 27 and fed to a controller. The latter has a counter 48 for counting the pulses from the signaller 17 and a second counter for counting the pulses from the signaller 27. When the number of pulses received by counter 48 is without a predetermined number of that set on the associated switch, the high speed motor of the associated coarse of fine drive is braked and the slow speed motors energized until the number on the counter almost equals that set on the switch whereupon the pressure in cylinder 33 allows the spring 34 to urge the roller 19, 29 into engagement with its dividing disc. When both rollers engage their discs, the indexing movement is complete. The distance between the notches of the fine drive disc 11 corresponds to a travel of 0À0001 mm. of the table 1 while that of the coarse disc 21 corresponds to 0À1 mm. travel of the table. During movement of the table, to reduce wear on the gearing, a thrust is applied to the table in the direction of movement by a pinion 45 driven by an hydraulic motor, the thrust being reversed on completion of the movement. Errors in the rack are corrected by a correction template 44 engaged by a follower lever 41 connected by levers 38, 39 acted on by a spring rocking an eccentric 37 engaging a bush 36, movement of the bush causing axial movement of the worm 10.

Abstract: 645,996. Gas turbine plant; axial-flow compressor. NAPIER & SON, Ltd.,D. Oct. 21, 1948, No. 27372. [Classes 110(i) and 110(iii)] [Also in Group XXXIII] An air intake assembly for a gas turbine plant comprises an annular air intake passage C arranged directly behind an air inlet orifice D which has a marginal contour, viewed in the direction of air entry, lying wholly within the inside circumference C<SP>1</SP> of the annular passage and a receptacle F for foreign matter situated inside the inner wall of the annular passage with an inlet opening directly behind the orifice D and at least equal in cross-sectional area to the orifice. Air entering the orifice D is therefore deflected radially in order to enter the annular passage C and heavy particles such as water or solid foreign matter are carried by their momentum into the receptacle F. These particles are carried away into the atmosphere by a stream of air passing intermittently or continuously through the passage G. Under icing conditions, hot gas from the engine is fed into the space J at the rear of the receptacle and from these passes in the direction indicated by arrows through the double walls of the receptacle. the inner and outer walls C<SP>1</SP>, C<SP>2</SP> of the annular passage and the wall H<SP>1</SP> of the nacelle H to the atmosphere. In a modification, the outer wall C<SP>2</SP> is fed by conduits directly from the space J and the hot gas from the inner wall C<SP>1</SP> passes into the air stream entering the compressor. It is stated that the diameter of the inlet orifice D is about half the external diameter and about two-thirds of the internal diameter of the air entry A into the compressor. When the turbine drives a propellor, the annular air intake may be formed by a ducted spinner in which case the receptacle F would be arranged within the central part of the spinner in front of the propellor boss.
