Title: Improvements in or relating to combustion chambers
IPC: F23R3/06
Filed: 1950-03-07
Abstract: 676,473. Generating combustion products under pressure. RICARDO, H. R., and ALCOCK, J. F. Feb. 22, 1951 [March 7, 1950], No. 5734/50. Class 51 (i). In a combustion chamber in which primary air enters through guide vanes B<SP>2</SP> in the same direction as fuel delivered by the nozzle C, and in which orifices G are provided for the admission of additional or dilution air, trough-shaped baffles or scoops G<SP>1</SP> project inwards into the combustion chamber at the downstream side of each of one or more of the orifices, the open side of the baffle facing upstream. Some of the dilution air is thereby carried into the central core of hot gases while the remainder spills over the sides of the baffles. The baffle may have a deflector J2 on its inner surface, or the sides of the baffle may have notches so as to cause some air to spill over the sides. The baffles may be stub-like or may extend diameterically across the chamber, and in the case of an air-jacketed combustion chamber the baffles may extend through the apertures into the jacket. The baffle may be U-shaped to provide a streamlined contour for the flow of air over it. Holes may also be formed in the baffle to allow air to pass therethrough.

Title: Improvements in and relating to electric control systems
IPC: H02P5/00
Filed: 1921-02-21
Abstract: 183,503. British Thomson - Houston Co., Ltd., (General Electric Co.). Feb. 21, 1921. Regulation, automatic systems and apparatus for; dynamos and motors combined for transmitting power.-An electric control system in which alternating-current motors are supplied includes a device depending upon the current and voltage of the supply and unaffected by change of supply frequency, for indicating directly that the motors are operating near their point of maximum torque, or for regulating the system so that the motors are maintained operating near that point. In the automatic regulating-arrangements shown the device controls the excitation of an alternator supplying a motor. When used simply as an indicator, the pointer of the device moves freely to one side or the other of a scale. and the necessary regulation is effected manually. In the arrangement shown in Fig. 2 a current coil 17 and a voltage coil 20 of high inductance or, as shown, in series with a relatively high inductance 25, act differentially upon vanes 22, 23 mounted on a spindle carrying a contact-making pointer 14 which closes the circuit of a reversible motor 33, the shaft of which operates to vary a rheostat 30 in series with the alternator field 29. In another arrangement the current and voltage coils act on cores mounted on the contact-making spindle, and the rheostat 30 is in series with the exciter field 32. Instead of vanes or cores, short-circuited cores may be carried on the contact-making element, these coils being positioned with their axes displaced from one another so that opposing torques are produced by the current and voltage elements. In another arrangement, shown in Fig. 5, the pilot motor is omitted and the contactmaking member shunts a relatively small resistance 55 in series with the exciter field and resistance 56, the later mechanism being so proportioned with respect to the former that the motor is maintained operating near its point of maximum torque.

Filed: 1974-02-08
Abstract: 1437689 Hydrogen O ISHIZAKA 8 Feb 1974 05905/74 Heading C1A A method for generating hydrogen comprises reacting metallic zinc with an aqeuous solution of ammonium hydroxide and/or an ammonium salt of an inorganic acid in the presence of a metal (other than zinc) or a compound thereof which is capable of forming an ammine complex. The ammonium salt may be (NH 4 ) 2 CO 3  or NH 4 Cl or a mixture thereof. The metal capable of forming an ammine complex may be cobalt (II), iron (II), aluminium (III), copper (I) or (II) or an alkali metal or alkaline earth metal. The zinc may be coated with a film of the other metal. The rate of hydrogen generation may be controlled by varying the concentration of the ammonium hydroxide and/or ammonium salt and/or by variation of the contact area between the metallic zinc and the reaction medium. The reaction is preferably carried out between 10‹ and 40‹ C. The reaction medium suitably contains 10-20% by weight of NH 4 OH and/or ammonium salt. The metal is preferably located out of direct contact with the metallic zinc. The reaction medium may contain two or more of the ammine complex forming metals. The ammine complex may be formed first and then poured over the metallic zinc or alternately zinc grains are placed in a porous vessel in a bath of the aqueous solution and the metal is introduced into the solution in the form of a powder or, preferably, a wire.
