Title: Improvements in automatic speed governing regulating means for internal combustion engines
IPC: F02D1/00
Filed: 1951-03-21
Abstract: 695,051. Speed governors. DAIMLER-BENZ AKT.-GES. March 21, 1951 [March 21, 1950], No. 6806/51. Class 57 [Also in Group XXVII] Automatic speed-governing means for internal combustion engines of the injection type comprising a governor, preferably a centrifugal governor, for an upper speed range and a hydraulically acting governor for a lower speed range, wherein the hydraulically acting governor comprises a spring- loaded piston which is connected to the fuel-regulating member of the injection pump and which is actuated upon by fuel at a pressure, substantially proportional to the engine speed, prevailing in the said pump. In the arrangement shown, a centrifugal governor 11, operative in the higher speed range actuates a lever 22 connected to the control rack 4 of a fuel-injection pump. The fuel-injection pump is fed by a fuel pump 7 actuated by a cam 13 on the governor shaft which is coupled to the shaft 2 of the injection pump. The fuel pump delivers to a passage 20 which is connected to the suction passage 40 through a relief valve 43 fitted with a throttle opening 41. The passage 20 is connected to a piston 36 connected by a lever 32 to the rack 4 and forms the governor operative in the lower speed range. The lever 22 is loaded at its pivot 23 by a torsion spring, manually adjustable, and loading the centrifugal governor. A stop 44 in the lever 22 is loaded by an idling spring arrangement which comprises a spring 46 engaging an abutment 47 loaded by a stronger spring 50 adjustable by a plug 49. Speed fluctuations at idling speeds are damped by the dash pot action of liquid passing through an orifice 48 in the abutment 47. The rack 4 has a pin 51, see Fig. 4, and its movement in a direction to increase the fuel is limited by the end 56 of a lever 55 which moves a lever 53 engaging a stop 58 through a leaf spring 57 which flexes to permit a slightly increased supply which is advantageous at low and medium speeds. A manually-operated lever 61 has a projection 63 for stopping the engine and also has an abutment 60 so that at starting, the lever 55 is raised by the abutment against the spring 59 to remove the projection 56 from the path of the pin 51 and enable the projection 62 on the lever 61 to move the rack to a position providing excess fuel.

Title: Improvements in and relating to the combustion of fuel
IPC: F23C99/00
Filed: 1930-03-01
Abstract: 349,915. Burning small fuel in suspension. GILL, H. A., 51, Chancery Lane, London.-(Stratton Engineering Corporation ; 116, East 18th Street, New York, U.S.A.) March 1, 1930, No. 6830. [Class 51 (i).] In the burning of crushed fuel in a combustion chamber to which an upwardly directed blast of air is delivered by a nozzle 3 at the lower end while the fuel is injected into the blast at a higher level, the velocity of the blast being so controlled that the fuel particles will be kept in suspension while the denser ash will fall, the combustion area is varied by moving the blast nozzle transversely to the combustion chamber, and the ash is maintained in a loose state by reciprocating a grate 6. The blast diverges upwardly so that its velocity at the fuel supply level will be insufficient to carry with it any substantial quantity of the fired particles of fuel, and any particles which are entrapped will be deposited in the chamber 9 and returned to the combustion chamber through the conduit 10. When it is desired to bank the fire the blast is reduced to allow fuel particles to accumulate at the bottom of the combustion chamber, and on restarting the blast this accumulation will be blown into the chamber and will ignite the incoming fuel. The volume of air supplied is from 15 to 30 per cent in excess of that required for complete combustion, and the fuel, which is crushed to pass a sieve of “ in. mesh, is injected with considerable initial velocity.

Title: Improvements in or connected with electrical apparatus for producing at a distance indications of the rotation and direction thereof of rotatable shafting and the like, particularly propeller shafts of ships
IPC: G01P13/00
Filed: 1921-03-02
Abstract: 182,161. Mechans, Ltd., and Mechan, H. March 2, 1921. Revolution-direction indicators. - Electrical apparatus for reproducing at a distance the movements of shafts, such as ships' propeller shafts, so as to indicate the direction of revolution, comprises a casing near the shaft enclosing a selector switch member set from the shaft to control the circuits of electromagnets at the indicating station, and a centrifugal circuit-completing switch. The electromagnets at the indicating station control a reversing-gear between the shaft of an electric motor and the spindle of the indicator driven thereby. The switch casing 10 is hinged at 16, Fig. 5, to a support, and frictionwheels 12 on a shaft 13 passing through the casing are pressed into contact with the propeller &c. shaft A by springs 17. The shaft 13 is geared to the switch shaft 11, on which is slidably mounted a member 19 having contact rings insulated from one another and from the shaft. This member 19 is rotated from the shaft by an inclined slot and pin connection 20, and is thereby moved to connect one of two contacts F, F<1> with a ring 18, and energize a corresponding electromagnet E, E' at the indicating station. The circuit-completing switch G comprises two stationary rings 24 and two brushes 23, 123, carried by a rotating weighted member 21 pivoted at 22 so as to assume an inclined position when rotating. One brush is held always in contact with its ring by a spring and the other makes contact only when the shaft 11 rotates. At the indicating station an electric motor C in the same circuit as the magnets drives a worm 3 in one direction only, and wheels 4, 4<1> in opposite directions. A pinion 6 on a pivoted arm 7 is brought into gear with either of two wheels 2, 2<1>, in one with the wheels 4, 4<1>, according to the movement of a rocking member carrying armatures 9, 9<1>, and drives a wheel 5 on the indicator spindle 1 accordingly. The indicator may be in the form of a propeller B, mounted in front of a translucent dial, which may be illuminated. The pivoted arm 7 may be provided with means to maintain it in its normal position with the wheels out of gear. According to the Provisional Specification the indicator spindle may be carried in a rocking frame moved by the electromagnets to change the direction of the drive, and the selector switches at the shaft may comprise a radial contact arm frictionally mounted on the shaft so as to swing over to one or the other of fixed contacts.

Title: Improvements in and relating to Steam Superheaters.
Inventor: PARSONS CHARLES ALGERNON
IPC: F22G3/00
Filed: 1916-05-13
Abstract: 108,690. Parsons, Sir C. A., and Cook, S. S. May 13, 1916. Overheating of superheating - tubes, preventing. - A superheater is provided at its outlet end with a relief-valve adapted to blow off at a lower pressure than the boiler safety-valve. The pressure at which the reliefvalve blows off may be adjusted automatically by a thermostat in the superheater or by a pressure-operated device. The relief-valve 1, Fig. 4, is controlled by a thermostat consisting of concentric alternate steel and copper alloy tubes 5, 6 placed in an enlarged superheatertube 3. An increase in the steam temperature causes the valve-spring cap 10 to lift, and so reduces the spring pressure and the blow-off pressure of the valve. In modifications, the lever 13 engages a sliding piece between two springs on the valve spindle, or engages the spindle directly. A thermostat 21, Fig. 6, placed between the superheating-tubes consists of a flat bar of alloy riveted at one end to the free end of a double bar, which is slidably supported on a bracket 36. The thermostat operates a relay valve 23 controlling the supply of steam through a pipe 27 to a chamber 28 containing an enlargement of the valve spindle 30, the steam pressure acting on the enlargement in opposition to the pressure of the spring. A relief-valve may be connected by a pipe to a highpressure steam space of the main engines, the steam pressure acting on an enlarged part of the valve. The relief-valve 51, Fig. 9, is controlled by the drop of pressure of the steam in passing through the superheater, which drop varies with the quantity of steam passing. Steam from the superheater inlet is led by a pipe 55 to a chamber 54 containing a piston 53 on the valve spindle and forces the relief valve on its seat against the upward pressure of a spring 57 and of the superheated steam acting on the face of the valve. The pressure drop through the superheater may be increased by restrictions in the inlet or ontlet pipe, or by a valve 59 having a weak closing spring.

Title: Improvements relating to electrical logging
IPC: G01V3/24
Filed: 1954-03-11
Abstract: 799,041. Electric well-boring tests. BRITISH PETROLEUM CO., Ltd., MANN, F. H., and MACDOUGALL, D. March 11, 1954, No. 7087/54. Class 37. Apparatus for determining the resistivity of the walls of a bore-hole comprises means for measuring the power sent into apparatus located in the bore-hole whose impedance is determined by the wall formation. As shown (Fig. 1) a constant current generator B supplies a valve V feeding an electrode P<SP>1</SP> in the bore-hole, whereby current flows in the surrounding media to create a potential difference between further electrodes P<SP>2</SP>, P<SP>3</SP>, which potential is applied to the grid of valve V via a transformer T to alter the impedance of the valve. Thus, the voltage E developed by the generator B to maintain a constant current output is a measure of the pick-up potential between electrodes P<SP>2</SP>, P<SP>3</SP> and therefore a measure of the resistivity of the walls of the bore-hole. The valve may be other than a triode, and may be duplicated, the two valves being connected anode to cathode to allow current to flow from electrode P<SP>1</SP> in both halfcycles. The valve-heaters may be supplied from local batteries or from a transformer carrying the constant current, which may be reduced except when a measurement is to be made. Alternatively germanium diodes may be used. Another embodiment (Fig. 3) uses a magnetic amplifier K with positive feedback, the potential between electrodes p<SP>2</SP>, P<SP>3</SP> supplying the control winding L<SP>1</SP> to vary the impedance of the A.C. windings L2, L3.
