Title: Improvements relating to Signalling by Sound.
Inventor: DRAGOUMIS EMMANUEL
Filed: 1898-09-14
Granted: 1899-09-14
Abstract: 19,552. Dragoumis, E. Sept. 14. Signals, bell, foghorn, &c. - Relates to apparatus for producing sonorous signals, of such a nature as to enable a person hearing them to reckon the position in which the object, e.g., a ship, is situated with respect to the observer. The apparatus and the observer may be either on a fixed or on a movable object, for instance, on the coast or on board ship, and the sound - producing instruments may be of any suitable kind, such as sirens, whistles, bells, &c. In the arrangement shown in Fig. 1, two signalling- instruments of different kinds are located at the extremities of a line A-B of known length. These instruments are sounded simultaneously and the sounds repeated at definite intervals. An observer on the line C<3>-C<5> hears both signals simultaneously, but on the line C<1>-C<4> the sounds are heard with an interval between depending on the time taken by sound to travel the distance A-B. In intermediate positions, such as C<2>, the interval varies approximately as the cosine of the angle a, so that, the interval being observed and the length A-B being known, the angle a can be determined. The sounds may be of definite duration, and may also be sounded separately with a known interval between them. In the latter case, the sounds may be of the same or of different character. Two or more such sets of apparatus may be employed for determining the positions of two or more lines, which may cross each other at right-angles &c., or a series of such signals may be arranged in one line, and sounded at definite intervals, the direction being indicated by the nature of the sounds heard by the observer. Instead of employing a number of fixed signals, a single sounding-body may be arranged to travel at a known speed along a definite path. Thus, as shown in Fig. 5, an electric bell &c. may be mounted on an endless band, arranged to travel round pulleys a, b, &c. The bell is sounded at definite intervals by means of a battery, the terminals of which make contact with a series of contact plates mounted on the band and connected to the bell terminals. Hammers may also be fixed round the band, to strike the signalling body. The air which is compressed in front of the moving body may also be utilized to actuate signals, such as sirens, whistles, or vibrating plates. In this case, the sound may be strengthened by attaching a funnel to the front of the moving instrument.

Title: Improvements in Valves for Water Closets.
Inventor: KENNEY DAVID THOMAS
Filed: 1898-10-11
Granted: 1898-11-26
Abstract: 21,365. Kenney, D. T. Oct. 11. Water-waste preventers.- Regulator valves in service pipe. Within the casing C<1> is a fixed cylinder F, within which the main valve G works on its seat e. The valve is operated by a stem N which passes through a tubular extension g', and is fitted at the top with a relief valve h and weight H. When the lever is operated, the first effect is to raise the valve h ; the plate n then strikes the tube g<1>, and raises the valve G, allowing the flush to pass through the ports f. Closure is regulated by a time-passage I and the area of the annular space i. The latter part of the flush is obstructed, to serve as an after-flush, by a plate, loose upon the stem g<1>, which rests normally upon a ledge m. In a modification, the main valve G is made of a cylinder open at the bottom and closed at the top. For high pressure, the valve seat e is raised above the level of the inlet ports. By the use of these valves a series of closet basins may be flushed from the same cistern.

Title: Improvements in Metal Bending Machines.
Inventor: MIALL ARTHUR
Filed: 1898-11-10
Granted: 1899-10-14
Abstract: 23,672. Miall, A., and Amos, E. C. Nov. 10. Bending.-Relates to improvements in machines for bending angle bars and Z-, T- and other sections used for ships' frames, bridges, roofs, and other structures. The improvements are particularly applicable to the machines described in Specifications Nos. 12,256 and 19,623, A.D. 1896, and are described with reference to the latter. The ring B which carries the movable rolls to vary the curvature is moved by a hydraulic ram C' instead of a screw. The opposite sides of the piston are of different areas, and pressure is admitted to both sides, so that, by closing the valve, the rolls are positively locked in position. The necessary position of the ring is determined by a pointer J fixed to it, and pointing to a curve drawn on a drum G, driven by belt gearing &c. from a spring-mounted roller H' in contact with the bar H being bent. The drum may be replaced by an endless band, or several drums and pointers may be used side by side when the bar is very long. Where accumulators are not available, a steam cylinder a, Fig. 5, is used in conjunction with a fluid cylinder b, the valves d, f being operated simultaneously, the fluid cylinder supplying the locking action when the valves are closed. The drum G may be replaced by a sliding table, and the pointer may be fixed on the valve-operating lever and caused to follow the curve.

Abstract: 23,898. Soc. Des GÚnÚrateurs Ó Vaporization InstantanÚe SystÚme L. Serpollet. April 20, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Single-acting engines; crank chambers; cylinders, arrangement or disposition of; valves and valve gear.-Relates to improvements in steam engines working with superheated steam at high temperatures. According to the invention, the engines are provided with valve gear of great simplicity, and are characterized by the absence of stuffing- boxes, slides, and slide valves, and by the provision for abundant lubrication, and for a free exhaust without the aid of a slide valve. The type of engine is that in which a group of two or more horizontal or vertical cylinders are arranged in any suitable manner, the cylinders, single-acting, opening into a common chamber in which a simple drop-feed lubricator maintains a constant level. Fig. 1 shows two cylinders arranged opposite to each other and opening into a common chamber in which the crank works. The pistons are recessed and joined directly to the connecting-rods. The distributing-gear is of the beat-valve type, and comprises a small shaft parallel to, and rotated by, the engine shaft, carrying a cylindrical cam adapted to slide along a feather, and actuated by a nut mounted on a screw turned by hand or by a governor. The admission valves e are pulled by opposing springs k<1>, and are worked by one and the same cam. The cylindrical cam has two symmetrical inclines, and allows of forward and backward running or stoppage of the engine, and also of the variation of admission of the steam. Apertures f in the cylinder wall allow the steam to exhaust freely.

Title: Apparatus for Simultaneously Actuating from One Point the Controlling Switches of the Several Electrical Motor Cars of a Train.
Filed: 1898-12-16
Granted: 1899-04-01
Abstract: 26,649. Siemens Bros. & Co., [Siemens & Halske Aktiengesellschaft]. Dec. 16. Electric locomotives and motor vehicles.-Relates to means for simultaneously actuating from one point the controlling-switches of the several electrical motor cars of a train. For this purpose, synchronously-running auxiliary motors m on each car are coupled by electromagnetic clutches to a shaft w<2> from which the controllers S are actuated, preferably through springs and a ratchet holding- device so as to give them step-by-step motions. The shaft w<2> is driven through gearings z<1> or z<3> at differing speeds and directions for the on and off position, and the clutches are excited from any one of the hand-switches u or g, which may normally rest in the off position. In Fig. 1, the main current is used for all purposes, and the switch consists of two double arms coupled together and working over contacts which excite the coils p, p<r>, and pv of the clutch so as to drive the controller S in one or other direction. In Fig. 2, a battery current is used for the clutches, and a single arm switch g sends the current through the coils p<v> and p<r> or through the coils p<r> only, or breaks the circuit altogether when the momentum of the motors is sufficient to return all controllers to the off or brake position, as the clutch K<v> is then released and the clutch K<r> thrown into action by the spring f<r>. Any interruption of the circuit produces similar results.

Abstract: 1994. Feeny, V. I., [Allgemeine Elektricitõts Ges.]. Jan. 29. Energy meters.-An induction motor meter for a three-phase three-wire alternating system, which may be unequally loaded, has a rotary disc A acted on at opposite sides of its spindle by two coils in mains J', J<2>, co-operating respectively with pairs of coils s<1>, s<2> in a shunt circuit between the mains J<1>, J<3>. The currents in the pairs of coils s<1>, s<2>, are respectively 90‹ and 150‹ out of phase with, the currents in the mains J<1>, J<2> when the load is balanced and non-inductive. This phase displacement is obtained in the coils s<2> by connecting the shunt circuit so that the current in it flows reversely to that in the coil in the main J<2>, and making the shunt circuit with such inductance as to give 30‹ displacement. Additional phase displacement of 60‹ in the coils s<1> is obtained by a non-inductive shunt resistance r. The disc is retarded by a permanent magnet M. Instead of the single disc, two discs on one spindle may be acted on separately by the two magnetic systems, as in the meter described in Specification No. 3056, A.D. 1900. The principal object is to reduce the consumption of energy in shunt circuits.
