Title: Apparatus and Means for ascertaining by Laboratory Experiments the Behaviour of Ships on Waves.
Inventor: RUSSO GIOACCHINO
Filed: 1899-02-02
Granted: 1900-03-02
Abstract: 2387. Russo, G. Feb. 2. Ships' design. -Relates to devices for experimentally determining the rolling movements of a ship. A pendulum, such as is shown in Fig. 1, is caused to roll on a plate L, which is given rotary and oscillatory movements corresponding to those of a portion of the surface of a wave. The oscillations of the pendulum are similar to those of the ship to be investigated according to Newton's law of mechanical similitude. In Fig. 1, the line C, C is the locus of the various centres of buoyancy of the ship, of which a midship section is shown, and G is its centre of gravity. The pendulum consists of a rod A-B, to which weights H, H are adjustably secured. F, F are two knife-edged plates resting on grooved bars on the plate L, their edges being parallel to the centres C, C. A block of wood or the like D is fixed to the pendulum so that it rubs on a leather or other band C, shown in Fig. 3, in order that the extinction curve of the pendulum shall correspond to that of the ship. The curvature of this block is determined by experiment. The pendulum and plate are placed in a machine, shown in Fig. 4, driven by an electromotor E at a constant speed. The plate L is rotated and oscillated by the means shown, and the pendulum oscillate, in a manner corresponding to the ship, a record of these movements being made on a moving paper band.

Title: Improvements in Valves for Air Brakes for Railway Vehicles and Similar Purposes.
Inventor: BOULT ALFRED JULIUS
Filed: 1901-12-02
Granted: 1902-05-22
Abstract: 24,506. Boult, A. J., [Christensen, N. A.]. Dec. 2. Brakes, air. Relates to drivers' valves fitted with automatic regulating or feed valves, and the chief object is to restore the normal pressure in the tram-pipe, after a service application of the brakes, without manually operating the feed-valves. The valve casing is in three parts a, b, c, of which the part a, shown in plan in Fig. 8, has ports g, h, i leading to the main reservoir, train-pipe, and exhaust respectively, while the part b has corresponding ports j, k, l, a passage m connecting the ports j, k, and a graduation port n fitted to the port l. The section c has a neck o in which the tubular valve-operating stem p turns, and this stem has a recess in which is fitted a plate x, having a guided spring stem y, and clamped to the diaphragm 2 secured by the ring 3, which has lugs 7 for engagement with the lugs 8 on the valve proper q. In the valve q is a port s for registering with the portj, and a cavity t for connecting the train-pipe port k with the exhaust port l and graduating-port n. The valve q also has a hollow stem r, in which is fitted the winged stem v of the spring- pressed automatic feed-valve u. Ports 19, 20 cut in the cap c communicate respectively with the main valve chamber or the space between the enlarged end of the stem p and the cap c and with the space between the stem and the neck o of the cap, and a passage 21 in the stem is adapted to register with one of these ports. When the valve q is turned to the "service" position, as in Fig. 3, the ports 19, 21 communicate, and air flows through them above the diaphragm and balances the train-pipe pressure on the underside of the diaphragm, while the spring 1 causes the projection on the plate x to open the valve u. If, now, the valve is turned to the ''lap" position, the compressed air above the diaphragm is retained, and the diaphragm is balanced so that the valve u remains open. At the "release" or "running" position of the valve, the ports 20, 21 register as shown in Fig. 2, and the compressed air above the diaphragm can escape very slowly through the small clearance space between the stem p and neck o, and, as in this position there is free communication between the train-pipe and the main reservoir, the feed-valve u being still held opeu, the brakes are positively released without manually operating the feed-valve. A push-pin 16 for operating the valve u in case of an emergency has a valve 18 adapted to close against the seat in the cap 17. The handle 11, fitted over the squared top of the stem p, has a spring detent which presses against the notched flange 13, and a projection 14 passing under the flange 13 prevents the removal of the handle except when the valve q is at "lap," and the projection 14 is then opposite a notch in the flange.

Abstract: 26,363. Karavodine, V. Dec. 24. Resins and resinous compounds.-Consists in producing insulating material with a basis of resinous substances or drying oils. Powdered resin such as bitumen, gum-lac, pitch, or other similar substances which will not readily decompose at 250‹-300‹ C., or drying oils are mixed with 25 to 35 per cent. of powdered sulphur, and to this mixture is added by malaxation, either cold or hot, 30 to 70 per cent. of inert fibrous or pulverulent materials, such as asbestos, sand, or pumicestone. The whole mixture is then heated in a vessel with a loaded cover while still mixing, to 350‹-400‹ C., until it becomes almost solid. The product is compressed in moulds heated to 250‹-400‹ C., or it may be first ground and then compressed. The resins or oils employed may, prior to use in the process, be heated to 300‹-350‹ C., for driving off a portion of their volatile constituents.

Abstract: 28,713. Unge, E. Dec. 30, A.D. 1901, [date appliedfor under Patents Act, A.D. 1901]. AÙrostats. - A balloon is designed to prevent loss of gas and to regulate its pressure. It is cylindrical, with either a conical or ellipsoidal top B, or it is conical. The cloths are arranged horizontally with only one vertical seam, and those on an ellipsoidal top are arranged radially. The appendix is closed, and its appearance indicates the pressure in the balloon. It has a casing E which protects it from the weather and variations of temperature. The cover is distended at the bottom by horizontal cones t, and between it and the balloon are arranged air tubes F. A gutter e catches rain, which is conveyed to the car for ballast. The temperature of the gas in the balloon may be controlled by passing air currents through the cover and out by the valve x or by circulating heated air through a pipe in the balloon. The valve is situated below the top, so that all the gas does not escape if the valve refuses to close. The car is attachad by a piece of stiffened canvas which tends to form the edge of a parachute when the balloon is falling.
