Title: Means for Converting an Engine into a Coal Gas Compressor, applicable also to other uses.
Inventor: MURPHY STEPHEN JAMES
IPC: F04B41/04
Filed: 1917-11-14
Abstract: 120,622. Murphy, S. J. Nov. 14, 1917. Actuating pumps by fluid-pressure motors; compound piston pumps; heat of compression, absorbing; valves, arrangement of.-A multiplecylinder engine, such as an internalcombustion engine, is converted into a compressor for coal gas, air, &c., or a pump for liquids, by attaching a cylinder such as D of smaller diameter to the end of one of the ordinary cylinders E of the engine, and mounting a plunger such as A on the engine piston G to compress coal gas, say, in the cylinder D and deliver it past a non-return valve H into a reser voir. The engine piston and cylinder may be employed merely as a motion block and slide respectively, in which case the piston may be perforated to diminish air resistance. The cylinder has one or more holes in it, and gas is admitted to the additional cylinder through a side port uncovered by the plunger or a non-return valve. Alternatively, the engine cylinder may be employed to compress gas up to its limit of strength and then be cut out automatically. In the form shown, gas is admitted to the cylinder E past a valve, actuated from the piston G, and through a port J, is compressed in the cylinder E, passes through ports C into the hollow plunger A and past a non-return valve B into the cylinder D where it is further compressed, and finally is delivered past the valve H to the reservoir. The plunger has piston rings and behind these clearance is left for the passage of the gas to the ports C which may be fitted with valves. A cooling- water jacket L is secured by ties K around the cylinder D and communicates through passages P with a jacket M surrounding the cylinder E and provided with a filling-top N. Several compressors with plungers of different diameters may be employed to effect multi-stage compression, or they may deliver the gas at different pressures to separate containers. When liquids are to be pumped, the inlet valve is connected to a liquid supply and the valve H delivers to a storage tank.

Abstract: 1,219,477. Regulating I. C. engines; fuel injection pumps. ALLIS-CHALMERS MFG. CO. April 8, 1968 [April 10, 1967], No. 16744/68. Headings F1A and F1B. [Also in Divisions G1 and G3] A device for moving a control member 20, on the reciprocating and rotating pumping plunger of a fuel injection pump, Fig. 1 (not shown), angularly and axially to vary the timing and quantity of fuel delivered to an I. C. engine comprises a centrifugal governor 19 which causes axial and angular movement of a member 36 controlling the member 20. A linkage 29, 33 connected to the member 36 transmits angular movement to the control rod 24 via a pin 26 and a plate 25 and a linkage 41, 42, 45 transmits axial movement via a pin 27 and the plate 25. The linkage 41, 42, 45 is pivotable about a manually adjustable pin 46 when the engine speed decreased from a high idling no-load speed (A) Fig. 2 (not shown), to increase the injection pump delivery. When the engine speed is reduced below a predetermined rated speed (B), Fig. 2 (not shown) the linkage 41, 42, 45 pivots about an adjustable pivot screw 49 to provide an increasing, constant or decreasing fuel delivery. With further decrease in engine speed the plate member 45 of the linkage is pivoted about the point 8 by the screw 48 and fuel delivery is decreased. At a selected speed (H), Fig. 2 (not shown) the force of a spring (59), Fig. 15 (not shown), biasing the stop 60 for the lever 50 carring the screw 49 is overcome and the fuel delivery is increased. The pin 46 is connected by a crank 39a, Fig. 6, to a shaft 39 which is manually operable to set the control characteristics of the device. A shaft 40 is operable to move the pin 46 to prevent fuel delivery. The pivot screw 49 may be replaced by a nut (95), Fig. 17 (not shown), on an adjustable bolt (53) and the supporting lever (80) may be adjusted vertically be a device (90) which operates in accordance with the fuel viscosity. The viscosity measuring device includes orifices defined by two different metals in order to compensate for ambient temperature variations. The pivot nut (95), Fig. 17 (not shown) may be moved vertically by a capsule (100), Fig. 19 (not shown), which is subjected to the barometric pressure or the engine intake manifold vacumm. The angular movement of the member 36 and the linkage 29, 33 is produced by engagement of the eccentric pin of an adjustable screw 30 in a slot 32 in the linkage plate 29.

Abstract: 413,120. Sewing - machines. ARMSTRONG, J. J. V., 12, Church Street, Liverpool.-(Union Special Machine Co. ; 400, North Franklin Street, Chicago, U.S.A.) June 16, 1933, No. 17195. [Class 112.] Feed-bar mechanisms.-The feed bar is reciprocated positively by a direct connection to an eccentric member, this connection embodying an eccentric strap and means for varying the feed stroke without varying the effective stroke of the eccentric. The reciprocating movements of the feed dog 9 are derived from a crank pin 16 on the shaft 12. This pin is connected to arm 11 on the feed-bar 10 by a link 17 and pin 18. The lateral movements of the feed dog are derived from an eccentric 28 on the shaft 12. This eccentric works within a strap 29 with a rod 30 telescoping into a sleeve 31 carried by the feed rocker 24. The endwise movements of the rod 30 due to the eccentric strap do not rock the feed rocker. This is rocked by swinging movements of the rod 30. The feed length, and so the stitch length, is varied by the following mechanism. A link 34 is attached to the sleeve 31. This link is pivoted at 35 to a link 36 attached to the shaft 37. Attached to this shaft by an arm 38 is a rod 39 with a cylindrical head 40 located in a bracket 42 in the machine bed. A knurled nut 44, threaded in the rod enables this to be moved endwise to rotate the shaft 37 and vary the relative positions of the links 34, 36 and so vary the feed stroke. A part 46 of the rod may protrude through a hole in the cloth plate and be marked with graduations.

Abstract: 1,033,892. Radio signalling; modulators. MARCONI CO. Ltd. Feb. 18, 1963 [May 4, 1962], No. 17212/62. Headings H3R and H4L. In a radio communication system the pulse train to be transmitted is separated into two pulse trains, each comprising different alternate pulses of the first train, which are respectively modulated on to two carrier waves in phase quadrature to provide suppressed carrier signals. These suppressed carrier signals are then combined with each other and one of the unmodulated carrier waves prior to transmission and a receiver is provided to perform the inverse of the operation and reconstitute the original signal. The transmitting circuit (Fig. 1) comprises a pulse train source 1 whose output is applied to gates 2 and 3. Oscillator clock 12 is arranged to oscillate at the repetition frequency T of the pulse train from 1 and controls divider circuit 13 adapted to provide two oppositely phased square wave outputs at a frequency of T/2. The outputs of circuit 13 constitute gating signals for gates 2 and 3 so that the gates are opened alternately, thus dividing the pulse train from 1 into two trains each consisting of different alternate pulses. The pulse trains from gates 2 and 3 are applied to narrow band filters 4 and 5 (centred about T/2) respectively and then modulated in balanced modulators 6 and 7 on to a carrier wave from oscillator 9 applied directly to modulator 7 and in phase quadrature to modulator 6. The resultant suppressed carrier signals are combined at 10 with each other and the unmodulated carrier from 9. The receiving circuit (Fig. 2) comprises a band-pass filter 19 for selecting the carrier wave which is amplified at 20 and fed directly to phase detector 16 and in phase quadrature to phase detector 15. The receiver input it also applied directly to these detectors which demodulate the respective pulse trains. These are squared in squarers 18 and 17 and then applied to coincidence gates 23 and 22. These gates are controlled by oscillator clock 24 at a frequency of T/2 so that the pulses are narrowed to prevent overlap (this reverses the pulse broadening effect of narrow band filters in the transmitter). The original pulse train is then reconstituted in combiner 27.
