Abstract: 19,036. Slaughter, T. Aug. 25. Four-stroke-cycle engines.-A single oscillating sleeve valve surrounding the cylinder controls the admission of charges to the crank case and the transfer of these charges after compression to the combustion chambers of both four-stroke-cycle super-compression engines and two-stroke-cycle engines. The valve may also control the exhaust. Fig. 1 shows a four-strokecycle engine. The valve 4 is arranged between the cylinder 2 and the outside air or watercooled casing 5 bolted to the cylinder head and crank chamber respectively. The valve is rocked through a T-lever pivoted at 23 by levers 17<a>, 18<a> and cams 17, 18, one of which revolves at twice the speed of the other. During the suction stroke, mixture enters the combustion chamber through the port 6<a> while mixture previously drawn into the crank chamber through the port 7<a> is compressed and enters at the end of the stroke through the by-pass port 10<a>. A charge of air enters the crank chamber through the port 9<a> during the compression stroke and is admitted to the cylinder for scavenging at the end of the exhaust stroke. The exhaust port may be controlled by the valve 28 or by the valve 4. A throttle valve may be fitted in the admission passage between the two gas-ports 6<a>, 7<a> so that the crank-case admission may be cut off if it is desired to work on the ordinary four-stroke cycle. In this case, a crank-case relief valve may be fitted and opened when the throttle is closed. The throttle may be worked by hand or by a governor. The lower gas-port 7<a> may be cut out altogether and air admitted to the crank chamber at every revolution, the ordinary charge being heavily carburetted, or again the air-port may be dispensed -with. In a modified four-stroke engine, there are two inlet valves one of which is automatic and opens into the top of the cylinder, while the other is mechanically operated and opens into the closed outer end of the cylinder by way of the by-pass. The usual exhaust valve is fitted, and also a non- return air inlet for the outer closed end of the cylinder. The sleeve valve may be applied to a two-stroke-cycle engine, and be provided with ports for admission to crank case, by-pass to cylinder, and with exhaust ports.

Abstract: 23,653. Blake, G. G. Dec. 7. R÷ntgen-ray apparatus.-A device for locating bullets &c. by means of the X-rays comprises a pair of metal cylinders T, T', a needle N of known length embedded in a mass of wax or wood B, and a wooden distance-piece Z sliding in guides. The device is placed on a plate P together with a flat piece of metal M having a handle, the end of the piece Z and a metal piece M are moistened with silver nitrate, and the body S is placed so as to lie on the piece M and to be touched by the distance-piece Z. Two exposures are made on the same plate by shifting the X-ray tube from L to L<1> ; thus two shadows are formed of the cylinders, the needle, and the bullet &c. X, and only one of the piece M. By drawing lines along the shadows, the intersections give the points L, L<1>, and the proportion of length of shadow gives the height of the tube. The intersection of the lines from L, L' to the shadows of the bullets D, D', gives the position of the bullet X, and by proportion its height is found. To avoid calculations, the device shown in Fig. 6 may be used. This consists of two scales at right-angles, and the measurements read off on the plate are marked on the scales and the proportional triangles formed so that the solution can be read off by one of the scales. In place of a single plate, two plates connected by a metal strip, which may be disconnected, may be used. The silver nitrate leaves marks on the body to serve as guides to the surgeon.
