Title: Process for regulating the speed of alternating current machinery
IPC: H02K16/02
Filed: 1924-11-28
Abstract: 225,564. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Francaise pour l'Exploitation des ProcÚdÚs Thomson-Houston). Nov. 28, 1923, [Convention date]. Alternating-current motors; driving-arrangements. - Two alternating - current motors are mechanically and electrically connected so as to compound their rates of revolution additively or subtractively according to the electrical conditions. In one example, a commutator motor A<2> carries mounted on its shaft the primary member B<1> of an induction motor, the secondary member of which transmits the compounded revolutions to a shaft D. In addition to the mechanical coupling, tappings from the secondary of the motor A<2> feed current to a three-phase primary winding of the other motor B<1> and variations of speed are obtained by connecting the commutator brushes of the motor A<2> to different sections of the primary. In other combinations, movable brushes on the one motor feed current to the primary of the second motor, the frequency of the current varying with the position of the brushes. The Specification, as open to inspection under Sect. 91 (3) (a), describes combinations of machines wherein the motors have exclusively mechanical coupling through bevel gearing rope. and pulley mechanism &c. This subject-matter does not appear in the Specification as accepted.

Filed: 1976-07-15
Abstract: 1524263 Aircraft navigation system SPERRY RAND CORP 15 July 1976 [24 July 1975] 29443/76 Heading H4D In the vertical path control of an RNAV system when the A/C ascends or descends to a waypoint with an "at or above" or "at or below" altitude requirement, vertical steering is at a constant airspeed relative to reference airspeed. A warning is provided when the flight path angle is less than the straight line flight path angle to the waypoint from "at or above" waypoints, and when it is greater for "at or below" waypoints. Altitude error is displayed on a vertical deviation indicator in accord with difference between actual altitude and that of the next waypoint having a firm altitude requirement. For ascent or descent of the A/C to a waypoint through the pressure-barometric altitude transition, flight path angles are computed and used as the vertical steering reference to avoid steering discontinuity at the transition altitude. When an airspeed reduction is required in a descending A/C, vertical angles are computed and used to control the flight path to include a speed transition zone and still make good the desired waypoint altitude.

Title: Manufacture of benzene hexachloride
IPC: C07C17/02
Filed: 1951-12-18
Abstract: Benzene hexachloride is obtained by reacting benzene with chlorine in the presence of 0.1 part to 5 parts by weight of sulphur dioxide per 100 parts of benzene.  The process may be effected in the dark but is preferably carried out under the influence of actinic rays.  It may be carried out batchwise or continuously and is preferably carried out at 10 DEG  to 20 DEG  C.  When working continuously, benzene, sulphur dioxide, and chlorine may be fed to a glass chlorinator at a constant rate while at the same time a corresponding amount of the reaction mixture is withdrawn. The chlorinator is exposed to the light from a mercury arc lamp and the temperature of the reactants is held in the range from 10 DEG  to 20 DEG  C.  In examples: (1) chlorine and a small amount of sulphur dioxide are added over a period of 35 hours to benzene which is contained in a glass vessel and is vigorously agitated during the addition, the temperature being held at 10 DEG  C. and the entire solution exposed to an actinic light source.  The reaction mixture is then steam distilled to yield a mixture of isomeric hexachloro-cyclohexanes from which g -benzene hexachloride is obtained by crystallization from trichlorethylene; (2) benzene, chlorine and sulphur dioxide are fed at a constant rate into a chlorination apparatus exposed to actinic light and cooled with water while a corresponding amount of the reaction mixture is withdrawn from the reactor.  The benzene hexachloride produced contains an appreciable amount of the g -isomer.

Abstract: 968,195. Rotary pumps and motors. JAMES HOWDEN & CO. Ltd. Aug. 21, 1961 [Aug. 30, 1960], No. 29920/60. Heading F1F. In a rotary compressor or engine of the type comprising two or more rotors formed with intermeshing helical grooves and threads, the root and tip diameters of either or both rotors are gradually reduced from end to end of the rotor to provide tapered clearances, which compensates for the temperature gradient in use-so that, in operation, optimum working clearances for maximum efficiency are provided at all points along the length of the rotors. In Fig. 1 the tip diameter is gradually reduced from x at the inlet to x<SP>1</SP> at the outlet end and the root diameter similarly from y to y<SP>1</SP> to produce equal tapers t. Figs. 3 and 4 show female and male rotors having a 6 to 4 land combination, in which the full lines indicate the grooves and lobes at the inlet ends of the rotors and the chain-dotted lines the grooves and lobes at the outlet ends. The lobes of the male rotor and the grooves of the female rotor have the-same radii R which are constant along the lengths of the rotors but are on decreasing pitch circle diameters. In a modification (Figs. 5, 6, not shown) to provide the taper the radius of the male rotor lobes decreases going from inlet to outlet, and that of the female rotor grooves increases in the same direction. Specification 627,162 is referred to.
