Title: Improvements in and relating to Rotary Engines.
Inventor: ROUX HENRI
Filed: 1907-11-13
Granted: 1908-08-27
Abstract: 25,194. Roux, H., and Homsy, F. H. Nov. 13. Movable-abutment type, with rotary abutments. The shaft a carries two rotors, one of which is shown in section in Fig. 1 and consists of a disk c keyed on the shaft a and carrying a piston d. The pistons of the two rotors are placed 180 degrees apart in the rotor chambers b<1>, b<2>, Fig. 4, in the annular chambers e of which the pistons work. The side walls of the casings have grooves f<1> in which slide annular flanges c<1> of the pistons. At the top of the casings are placed the abutment chambers f in which work cylindrical abutments g having sector-shaped recesses on one side. The abutments are carried on the common shaft h, which is driven by toothed gearing from the main shaft. The shaft h also carries the distribution valve l, consisting of a sleeve l<1> keyed on the shaft and carrying two disks l<2>, l<3> enclosed in a box, of which the disk l<3> forms one end. The disk l<2> has a concentric semicircular slot l<5> which, when the disk revolves, uncovers successively two ports m<1>, m<2> in the valve-box. The steam is thus supplied in three stages : (1) the steam enters one rotor casing b<1> through the port m<1> and drives the piston therein ; (2) the ports m<1>, m<2> are both partly open and the steam is split and drives both pistons; (3) the steam is cut off from the first chamber and drives the piston in the second chamber, the steam in the first acting expansively in this stage. Between the two rotors is provided a regulating and reversing arrangement, which consists of two cylinders o<3>, o<4> in which work rods o<1>, o' carrying double plungers and connected at one end to a bar n<2> loosely mounted on a nut n' with a handle n<3>. The cylinder o<3> is connected to the rotor chamber b<1> by passages and orifices q<1>, q<2>, and to the part m<1> of the valve l by orifices r<1>, r<2> and a tube r<3>. The cylinder o<4> is similarly connected to the chamber b<2> and the port m<2>. By moving the nut n' along the spindle n, the steam may be passed into either side of the steam-chambers of the rotors to reverse the engine, while in the mid-position steam is cut off from both passages and the engine is stopped. A scale is provided the sections of which correspond to the three plunger positions, and an indicating- finger is provided on the bar n<2>. More than two rotors may be placed on the shaft, in which case the valve-box l is provided with a corresponding number of ports which are uncovered in turn, and the valve l may be operated by connecting-rods and eccentrics, instead of gearing, from the main shaft.

Title: Improvements in Power Transmission.
Inventor: THOMAS JOHN GODFREY PARRY
IPC: H02P9/00
Filed: 1907-11-15
Granted: 1908-11-12
Abstract: 25,386. Thomas, J. G. P. Nov. 15. Distributing. - Relates to electro - mechanical power transmission systems of the kind in which a prime motor and two dynamo-electric machines are mechanically interconnected through three members of an epicyclic gearing. The prime-mover A is connected to the planet-carrier D, the planet-wheels d, b gearing with sun-wheels g, f connected respectively to the armatures C, B. The field-magnet frames C', B' are stationary. On a hollow shaft E a brake P is arranged, and a clutch Q is adapted to connect the hollow shaft K to the load shaft H. The dynamo-electric machines are series wound or separately excited, and the field strength is varied by a shunt for the winding. The armatures of the machines are electrically connected. At starting, the wheel g is stationary, and the wheel f and armature B are rotating in a weak but increasing field B<1>. The current generated is led to the armature C, which starts the vehicle. As the vehicle gains speed, the field C' is diminished, and the armature B diminishes in speed, and may be held by the brake P. If the ratio of the diameters of the wheels b, f is twice that of the wheels d, g, the armature C is then rotating at half the speed of the shaft A. If the field C<1> is reversed and the brake P released, current is generated in the armature C and drives the armature B in the same direction as the engine shaft A. By increasing the reversed field C', the speed of the armature B may be increased to the speed of the shaft A, so that the whole of the gearing is rotating solidly. The clutch Q may then be engaged so as to give a mechanical drive at the top speed. The brake P may, under these circumstances, be used to retard the vehicle. The direction of motion is-reversed by reversing the field C' and exciting it strongly, and gradually increasing the strength of the field B. During reverse movements, the shaft H may be separated from the gearing and the sun-wheel g held stationary. The machine C may be connected up as a braking-generator, the current developed being dissipated in resistances or employed to drive the motor B against the brake P. In a modification, the prime-mover is connected to the smaller sun-wheel and the machine B to the planet-carrier. The apparatus is described in connexion with a motor vehicle, but is applicable for other purposes, such as winding - gear. In this application, the energy of the descending cage is stored in a flywheel by transmission through the machine C running as a generator and the machine B running as a motor.

Title: Improvements in the Manufacture of Hydrazine.
Inventor: RASCHIG FRIEDRICH
Filed: 1908-01-02
Granted: 1908-04-02
Abstract: 139. Raschig, F. June 6, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Hydrazine is obtained by the action on chloramine or a hypochlorite of much larger quantities of ammonia than are employed in Specification No. 22,957, A.D. 1907, the operation being performed in the cold. The yield is greatly increased by addition of compounds which increase the viscosity of the solution, such as a weak solution of cane-sugar, dextrose, lµvulose, mannite, lactose, glycerine, formaldehyde, starch, dextrin, gum arabic, albumen, casein, gelatine, isinglass, or ordinary glue. By the application of heat, the quantity of ammonia necessary may be reduced. In an example, three litres of concentrated ammonia, to which have been added 12 c.cs.. of 5 per cent solution of glue, are added to one litre of sodium hypochlorite solution ; heat is applied, the excess of ammonia is driven off, and the hydrazine precipitated as sulphate.

Abstract: 20,013. Zerbino, P. Sept. 23. Gate opening and closing apparatus.-A slidiug gate is constructed so that the operation of opening it sets in action a device for unlocking the mechanism that keeps the gate open after a suitable interval. The gate 2 is supported by wheels 7, 8 which run on a guide-rail 4 pivoted at 33 so that it can be tilted to cause the gate to move along the rail. The rail 4 is rigidly connected to a bar 3 on which is fixed the device for operating the unlocking-mechanism. This comprises a sinuous channel 11 and a straight channel 12 which open into a straight channel 13. When the beam 3, 4 is tilted by pulling the rods 26 so as to open the gate, a ball 14 runs down through the channel 11 and strikes against the plunger 15. This plunger actuates the bar 17, Fig. 4, and so frees the tooth 19 on the beam 3, 4 which thereupon tilts, and the gate closes. The tooth 19 can also be operated through the lever 20, wire 21, crank-lever 22 and chain 23. The front part of the guiding-frame 1 of the gate consists of a high post in the top of which is pivotally mounted the beam lever 24. The levers 27 are connected to the lever 24 and also to the fore end of the beam, which has antifriction rollers 32 to prevent it rubbing against the post. Stops 28 on the frame 1 prevent the wheels 7, 8 from striking against the standards, and a tooth 29 engages a closing-device 30, Fig. 5, at the exact moment the gate is closed. A catch 31 is provided to engage a notch at the front part of the gate and hold it open until the catch is released by hand.

Title: An Improved Method of Protecting Stereotype Matrices from the Penetration and Adhesion of Metal.
Inventor: COHN HUGO
Filed: 1908-10-16
Granted: 1909-02-18
Abstract: 21,953. Cohn, H. Oct. 16. Stereotype.-To prevent the liquid type-metal from penetrating into the pores of a stereotype matrix during casting, the matrix is coated first with a protecting layer of talc, China-clay, alum, &c. or with "collodin" (a gluey powder made from starch), and then with a material containing an easily-fusible fat, such as stearin, in a powdered condition. Or collodin and fatty material may be mixed and applied together. The stearin is preferably used in combination with talc or other mineral powder. After the impression is taken, the matrix is dried and heated so as to melt the fatty substance, which, together with the talc or other substance used, forms a protective layer over the surface of the matrix. The matrix should preferably be powdered with the fatty substance after every fourth or fifth casting.
