Title: Improvements in Duplex Pumps.
IPC: F04B9/12
Filed: 1917-04-23
Abstract: 107,564. Weir, G. & J., and Lang, C. R. April 23, 1917. Duplex arrangements.-In a duplex pump, each cylinder has two valves, one controlling the admission, cut-off, and release, and the other the compression. The valves are actuated bv transverse rocking shafts actuated by the piston-rods. Each piston, through the valve-gear, controls the compression in its own cylinder and the admission, &c. in the adjacent cylinder. One cylinder works one-quarter of a cycle or a half-stroke in advance of the other. One of the admission &c. valves is actuated so as to move in the same direction as the piston which drives it while the other admission &c. valve works in the opposite direction to the piston which drives it. The shaft s is driven by the pump-rod of cylinder A and drives the compression valve h, Fig. 8, of A through the lever y, Figs. 1 and 5, and tappets on spindle z, and the admission valve n of cylinder B through the crank S, loosely-mounted bellcrank 3, 4 in shaft r, anc. tappets on spindle 5. The shaft r is driven by cylinder Band drives the admission valve f, Fig. 6, of cylinder A through crank u and tappets on rod v, Figs. 1 and 4, and the oompression valve p of cylinder B through the crank W and tappets on the rod x. The steam passes to the cylinder A through passages 7, 8 until cut off on the downward movement of the valve f. The exhaust then passes through a passage 9 in valve f to passages 11, 12, Fig. 8. The exhaust is cut off on the downward movement of the valve h, To hold the exhaust valve up to its seat, steam is supplied to a passage 18, and a cavity 16 is provided which communicates with the exhaust by a passage 17. The cushioning is varied by adjusting the tappets on the compression-valve spindles. In the construction shown, the piston in cylinder B is one-quarter of a cycle in advance of that in cylinder A. In a modification, the converse is the case. In this modified construction, no lost motion is provided in the gear of the exhaust valves.

Abstract: 727,323. Spray carburetters. GENERAL MOTORS CORPORATION. March 5, 1952 [March 27, 1951], No. 5708/52. Class 7 (3). Tubes 40 manually rotatable about their longitudinal axes each communicate with the air space of the fuel chamber. By rotating one or both of the tubes the pressure in the fuel chamber can be varied. The tubes may be a tight fit in the wall of the intake passage so that when set in position they remain in this position. Alternatively they may be attached by screw threads and lock nuts. More accurate control can be obtained by use of two tubes. By setting the tubes in different positions any vapour which forms in the fuel chamber can be drawn off. As shown the carburetter is a dual carburetter having two mixture passages 8, 10 with separate throttle valves not shown on a single shaft. An unbalanced choke valve 28 is shown and it is controlled according to temperature and suction. A manually operated choke may be employed.

Title: Process for the extraction of metals or metalloids from their oxides
IPC: C01B32/942
Filed: 1921-02-19
Abstract: The general process for the reduction of oxygenated compounds to form metals, metalloids, carbides &c. by means of coal or hydrocarbon oils described in the parent case is utilized in the preparation of calcium carbide, and the process is rendered continuous by employing a rotary furnace in the following manner.  Lime or limestone and the necessary amount of coal and fluxes are charged by means of a feeding-device into the upper end of a horizontal or, preferably, slightly inclined rotary furnace and strongly heated air together with finely-pulverized coal or atomized hydrocarbon-oil are injected into the lower end.  The quantity of air admitted is adjusted so that there is only sufficient for carbon monoxide to be formed by the combustion. The combustible gases leaving the furnace are employed to heat the air before it is injected into the furnace.  The general process of the parent Specification may be conducted in a rotary furnace as described above.
