Granted: 1905-05-11
Abstract: 22,128. Merck, W., Merck, L., Merck, E. A, and Merck, C. E., [trading as Merck, E.]. Nov. 14, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. 4-Imino-2:6-dioxypyrimidines are produced by condensing urea or alkyl urea with cyanacetic esters with the aid of alkali metals or their alcoholates. In an example, cyanacetic ethyl or methyl ester is added to a mixture of alcohol or sodium. Urea is then added and the mixture is boiled under a reflux apparatus. The mixture is next neutralized, the alcohol is distilled off, and the mass is extracted with water. The addition of acetic acid precipitates the pyrimidine derivative. In another example, cyanacetic ester and methylurea are added successively to a cold suspension of sodium in xylene, and the temperature is raised gradually. Water is then added, the xylene is removed, and 3 - methyl - 4 - imino - 2 : 6 - dioxypyrimidine is precipitated by adding acetic acid.

The turbine wheels 10 are mounted on a shaft 14 and are separated by diaphragms 2, which are fitted with packing-devices of the kind described in Specification No. 13,192, A.D. 1904. A feedwater-heater 40 may be placed in the exhaust chamber beneath the last wheel. The nozzles 12, Fig. 2, for the first wheel are controlled by lift valves 50, each valve being operated by a grooved piston 54 having underneath it an auxiliary piston 52. The valveoperating pistons are controlled by a tubular valve or nozzle 91 adapted to direct a jet of steam either into a channel 75 leading to the pistons or into a channel 106 leading to the turbine wheel. The tubular valve is connected by a lever 96 to an eccentric 99 which oscillates the valve and causes a pulsation of the issuing jet. The valve lever is connected to a governor 97 which regulates the position of the valve, and thus the intensity of the jet acting on the valve-operating pistons. By means of passages 71 in the pistons and casing, one or more valves are opened according to the load on the turbine, and the extreme valve effects an oscillating adjustment. Each of these piston chambers is connected by passages 73 to pistons 84 in each partition, operating rotary plug valves 89 for the nozzles in the respective stages. The chambers for the plug valves are formed as radiallybored holes closed by plugs.

Patent GB-190511519-A (GB)
Title: Improvements in Air Brake Systems.
Filed: 1905-06-01
Granted: 1905-10-12
Abstract: 11,519. Lake, H. H., [Dukesmith Air Brake Co.]. June 1. Brakes.-Relates to means whereby the driver is enabled to control the engine and tender brakes independently of the train brakes in Westinghouse and similar systems. The main reservoir 1 is connected to the train-pipe 6 by the usual driver's valve 4. The engine brake cylinders 7 and auxiliary reservoir 20 are connected to the trainpipe by the usual triple valve 9. The tender brake cylinder has no separate triple valve, but is connected by a pipe 26 with the exhaust port of the triple valve 9 and by a pipe 39 with an additional driver's control valve 30, which also has connexions by pipes 40, 41 with the engine brake-cylinder pipe 25 and by a pipe 42 with the main reservoir 1, besides having ports 34, 36 opening to the atmosphere. The valve is shown separately in Figs. 3 and 4. The plug has two right-angled passages 45, 47, two horizontal grooves 48, 49 extending for ninety degrees, and one inclined groove 46 also extending for ninety degrees. The valve has four operative positions and is.checked in each by a spring catch 51 on the handle. In the position shown, the groove 46 connects the pipes 39, 40, and the other connexions are blanked. With the valve in this position, the engine and tender brakes are both applied at the same time as the train brakes but remain applied when the train brakes are released. To release the engine and tender brakes, the valve is turned through a rightangle, thus causing the passage 47 to connect the pipe 40 with the exhaust port 36, and the pipe 39 with the exhaust port 34. In one of the other positions of the valve, the passage 45 connects the pipe 39 with the exhaust port 34, and the engine and train brakes can then be applied and released together in the ordinary manner. In the fourth position of the valve, the groove 49 connects the pipes 41, 42 and admits air from the main reservoir to the engine brake cylinders. To avoid clogging of the tender triple valve, when one is used, by the condensed moisture and dirt from the train-pipe, a drip bag is placed in the train-pipe on the tender ; or the tender triple valve being dispensed with, the condensation is collected at the usual drip cup at the rear of the tender.

Title: Improvements in Roundabouts
Inventor: CLARKE WILLIAM HENRY
Filed: 1905-06-08
Granted: 1906-01-11
Abstract: 11,978. Clarke, W. H., and Wright, R. W. June 8. Roundabouts.-Roundabouts are constructed so that the cars receive a similar motion to cars moving on a circular switchback track, but the cars are suspended by means of wires from a rotating frame, and the vertical motion of the cars is obtained by drawing the suspending-wires n and out by means of an eccentric. Each car K is suspended from a jib J, supported by spars B, G, by means of two wire ropes H, one at each end of the car, each rope H being provided with a ring L, from which are suspended two ropes attached respectively to the front end of one car and the rear of the adjacent car. The spars B are attached to a plate S which moves round with the sbaft A. The shaft A is driven by means of a band U formed in two halves capable of being adjusted by means of bolts and springs so as to engage a friction drum T, fixed to the plate S. The band V is connected to the main driving-wheel W, loosely mounted on the shaft A and driven by suitable power. The rotation of the shaft A drives an eccentric E, loosely mounted on the shaft, through the operation of bevelwheels D, 0, M, the last being loosely mounted on an arm N fixed to the shaft A. This gearing causes the eccentric E to revolve in the opposite direction to the shaft A. The gearing may be arranged so that the eccentric revolves at a different rate from the shaft A. The eccentric E is surrounded by a ring or strap R running on rollers, and the ropes H, which are suitably guided by pulleys &c., are attached to the strap R, so that, for each revolution of the eccentric E, the cars K rise and fall through a certain distance. The cars K are guided in their vertical motions by rods Q attached to the beams C, which are connected to the cars by means of pins Z, about which the cars oscillate. The rods Q move through guides V on the spars G, and serve to prevent the cars from moving outwards by centrifugal force.

Title: Improvements in Radial Railway & Tramway Trucks.
Inventor: WARNER JAMES SUTHERLAND
Filed: 1905-07-21
Granted: 1906-02-24
Abstract: 15,059. Warner, J. S. July 21. Axle-trucks or under - carriages.-The axletruck is suspended from the axle-boxes by links which, when the vehicle is running round a curve, swing in a circular arc around the central pivot g, about which the sub-truck frame f turns relatively to the truck frame b. Roller connexions may be fitted to the suspension links, the rollers being arranged to run up slightly-inclined planes when displaced from their normal positions. In the example shown in Figs. 1 and 2, the axleboxes d are bolted to the sub-truck frame f, and each axle-box carries a plate h fitted with projecting bearings i, the axes of which, if produced, would intersect at the pivot g. Vertical or inclined links j, suspended from these bearings, carry each a washer or washers l, upon which rests a supporting-spring m for the frame b. The links may be jointed, as at o, or chain links may be employed. In a modification, Fig. 6, the plates h are in one with the sub-truck frame f, and the underside of the plates and the top of each axle-box are made with interlocking ridges q so that any axle-box can be readily removed. Each plate h has recesses r, for the eyes of the links j, and recesses t to permit of pins u being passed through the eyes. A stirrup v, Fig. 7, for use when a semi-elliptical spring y is employed, is placed diagonally across the top of the axle-box a, and the spring extends between the two limbs of the stirrup. The hole g<1>, Fig. 2, in the truck frame, through which the pivot g passes, is elongated transversely, to prevent the wheel flanges from being locked against the rails when the vehicle is stopped on a sharp curve. In Figs. 9 and 11, the chain links j support the frame b through rollers z, bearing against inclines z<2>, the chains being suspended from plates h which are supported on springs o<1> on the axle-boxes. The rollers z may be fitted to the upper ends of the links, Fig. 13. A roller may be applied to the top bar of the stirrup v, Fig. 7, or to its lower part, as shown in Fig. 16. Fig. 17 shows the roller z arranged on the top of the axle-box in connexion with a spring z<4> from which the links are suspended. According to the Provisional Specification, the links may be composed wholly or in part of springs, and they may be adjustable in length. When a leaf-spring is employed, it may be arranged diagonally across the axle-box in a rounded channel, or, when it is slung beneath the axle-box by a stirrup, it may be grooved to rest on a rounded diagonally-arranged bar, supported by the stirrup. The axle-boxes may have inclined faces to bear against similar faces on the truck frame, in which case lugs may be used to restrain the twisting tendency of the boxes. The wear of the brasses from this twisting tendency may be eliminated by coupling together the boxes at each end of the axle, or by causing the inclined sides of the axleboxes to bear against vertical rollers in the frame.

Abstract: 21,038. McNulta, H. Dec. 10, 1904, [date applied for under Patents Act, 1901]. Distributing.-Relates to motor systems with electric transmission of power on locomotive vehicles and boats. A turbine or other motor 1 rotates the armature 3 of an alternating-current generator, the field of which is connected to the driven shaft 7, shown in Fig. 1 as carrying a screw propeller. This shaft carries the armature 11 of an alternating- current motor, the field of which is stationary, and which is supplied with current from the generator through a transformer 14, the ratio of the transformer being controlled by a switch 16. The generator is excited from an independent source 5, and the exciting-current may be controlled by any ordinary arrangement. A reversing-switch 18 is provided in the circuit of the motor. Fig. 2 shows a method of applying the invention to locomotives. The rotors 21 of the turbines drive the armatures 24 of the generators, the field systems of which are internal and are rigidly connected to the vertical shafts 22, which drive the wheel axles through bevel-gearing. The generators supply current to a number of motors 33, coupled to the other axles of the locomotive, or to the axles of the tender or the train of cars. In the example shown in Fig. 2, the armature of the generator is wound for three-phase current, and a motor, transformer, and reversing-switch are connected up in the circuit of each phase.
