Inventor: SMALL JAMES MILN
Filed: 1903-07-28
Granted: 1903-10-15
Abstract: 16,584. Small, J. M. July 28. Gas turbines.-Consists first in propelling a turbine or the like by means of a stream of pressure fluid produced by a continuous succession of explosions of a mixture of gas or oil and air, and secondly in apparatus for generating the pressure fluid. Fig. 1 shows a valve n for controlling six combustion chambers a, only one combustion chamber being shown. The suitablyrotated valve n has a central chamber filled with compressed air from the main pipe b. The valve casing has a set of three chambers i, Fig. 2, for each combustion chamber, and the valve has a port o for each set of chambers and adapted to admit compressed air to the chambers in rotation. These chambers are connected by pipes m<2> to piston chambers c<4>, and, as the valve rotates, the piston c<3> is first raised opening the air valve c so that air is admitted to the combustion chamber, then the valve f<1> is opened carrying with it in the annulus g a charge of gas or oil. The mixture is exploded and finally the outlet valve e opens and the exploded gases pass to the motor supply pipe d. The ports o are angularly spaced, so that a continuous rotation of explosions is produced in the chambers.

Title: Improvements in Drain Valves for Cylinders of Steam Engines and the like
Inventor: KENNEDY-MCGREGOR JOHN ALEXANDE
Filed: 1903-08-22
Granted: 1904-05-05
Abstract: 18,136. McGregor, J. A. Kennedy-. Aug. 22. Cylinders, draining.-The water escapes into a chamber through an orifice controlled by a valve, and from the chamber into a drain pipe controlled by a valve which opens when the first valve closes. A pipe M, N from each end of the cylinder communicates with a cylindrical valve-casing C through an orifice controlled by a valve A, B. The spindle a<2> of the valve A slides in the interior of the spindle b<2>, and is connected with a piston-valve A' by a pin a<3> which passes through slots in the spindle b<2>. A spring E, confined in the interior of the spindle b<2> and acting on the end of the spindle a<2>, tends to force outwards the valves A, B, and to press together the valve A<1> and a valve B' formed on the spindle b<2>. If no pressure acts on either valve, both valves A, B and the pipe F will be open. If pressure acts on both valves A, B, the valves A', B' will be forced apart, and so close the pipe F, while, if pressure acts on either the valve A or the valve B, the valve acted on will close, and will so open the chamber on the same side to the pipe F. In a modified arrangement, the valves A, B, and a single valve controlling the pipe F, are formed in one with a common spindle.

Title: Improvements in, and relating to, Brake Mechanism for Velocipedes and other Road Vehicles.
Filed: 1903-11-16
Granted: 1904-09-22
Abstract: 24,932. Dring, J., Trigwell, J. R., and Bowden's Patents Syndicate, E. M. Nov. 16. Brakes.-Relates to improvements upon the inventions described in Specifications No. 20,512, A.D. 1899, and No. 21,380. A.D. 1900, [Abridgment Class Mechanism &c.], and consists chiefly in the use of the Bowden mechanism for operating two brakes upon a velocipede, motor car, or other road vehicle by means of a lever fulcrumed on the frame. As applied to a velocipede, the lever f with equal or unequal arms, is pivoted upon a pin d, which is capable of sliding in the slot c of a plate b fixed on the lamp bracket, handle-bar stem, or other part of the frame. A main length of the incompressible member i of the mechanism passes through a stop h adapted to be received by a lug g, and is connected to a nipple j. The nipple of a further length of Bowden mechanism, preferably connected to the back brake, is received by a joint k, while the other joint k<1> takes the end of a telescopic rod or the like l for the front brake. To prevent both brakes from being put out of action in the event of a breakage of one of the operating-members, the end of the main member passing through the nipple j may be attached to the upper part of a flanged bridge-piece m, Figs. 5 and 6, secured to the pin d. The bridge-piece has wings n, while a part o enters the slot, so that too wide a range of rocking movement of the lever f is prevented. In lieu of this arrangement to limit the action of the lever, a plate or frame on the pin may carry adjustable studs, or the ends of the frame may be turned at right-angles to form the stops. The front brake may be operated by Bowden mechanism, or the device may be used to apply two band or other friction brakes.

Abstract: 5549. Richardson, J. C. March 7. Camphors; borneol; terpenes.-Artificial camphor, C10H17Cl, is converted into borneol, or isoborneol, and this is oxidized to form camphor C10H16O. Artificial camphor, alcohol, water, sodium hydroxide, and sodium formate, or other salt capable of reducing artificial camphor and soluble in alcohol, are mixed together in the order named. The mixture is heated in an autoclave at about 120‹ C. for about 10 hours. After cooling, alcohol is distilled off on the water bath. The residue is acidified, and borneol &c. is distilled off with steam. The borneol is dissolved in benzene, or other neutral solvent, and is oxidized by means of permanganate, or the like, to camphor. The camphor is separated by steam distillation and filtration, and is purified by recrystallization from ether or the like. According to the Provisional Specification, an improved artificial camphor is produced by heating artificial camphor with oxalates, formates, and the like, and free alkali, and steam distilling.
