Title: Improvements in or relating to directional aerial systems
IPC: H01Q21/14
Filed: 1940-09-23
Abstract: 563,493. Directive wireless systems. CORK, E. C. Sept. 23, 1940, No. 14491. [Class 40 (v)] A directional aerial system comprises three elements, two having a minimum in the same direction and the third a minimum in two opposite directions in the same plane as, and perpendicular to, the first direction, the elements being so arranged that the transmission or reception efficiency increases continuously with angle between the said two opposite directions. The aerial system consists of three radiating elements lying in a single plane and formed by a bent wire ABCDEF, one end A being attached to the inner conductor 1 of the screened feeder 2 and the other end F being connected to earth through a resistance 3 equal to the characteristic impedance of the wire to prevent reflections. The wire is bent into equal loops ABC and DEF at right angles to the length of the wire, the loops forming two of the radiating elements and being equal in length to one quarter of the operating wave-length. The wire CD forming the third radiating element is of a length equal to a quarter of the operating wave-length. The loops ABC and DEF have minimum or zero radiation along the axes of the loops and a maximum in a medial plane normal to the axes. The radiation from the two loops cancels in the direction CD and adds in the direction DC. Radiation from the wire CD is zero in the directions CD and DC, but a maximum in a medial plane normal to CD. In the plane of the bent wire, the total radiation is a maximum in the direction DC, half this maximum in the direction AB, and zero in the direction CD, varying between these limits directly with the angle. To avoid ambiguity, the wire may be associated with a reflector to prevent radiation or reception from unwanted directions. The earth connections shown may be centre tapped half wave-length conductors. The feeder 1,.2 may be coupled to the wire ABC DEF by an impedance matching transformer. Switching means may be provided to interchange the feeder 1, 2 and the resistance 3 so as to reverse the polar diagram. Instead of a bent wire system, separate aerial elements may be fed by separate feeders with appropriate phasing of the currents.

[Also in Division F1] A device for feeding a freely flowing material to a machine tool comprises a container rotatably mounted on an inclined axis and adapted to receive said material, means for rotating said container, and a helically formed tube fixedly mounted in said container, the lower end of said tube being open to receive material from said container and the upper end of said tube opening outwardly of said container to feed material therefrom upon rotation of said container. A lapping machine comprises a box-like housing 6, preferably of sheet metal, having a top surface member 7 provided with a circular opening 8 accommodating a radially-grooved lap 9. Below the member 7 and attached thereto, e.g. by welding, at the periphery of the opening 8 is a combined drip pan and supporting member 10 having a circular opening 11 defined by a flange 12. Bolted to the underside of the member 10 in axial alignment with the opening 11 is a tubular support 13 carrying a worm drive gear box 14 and a drive motor 15. A hub 17 keyed to the output shaft of the gear box is journalled in the support 13 and projects through the opening 11 in the member 10. The lap 9 has a central circular opening 22 having an inwardly projecting flange 21 which is held against a flange 19 on the hub 17 by a disc 23 secured by a stem 24 threaded into the hub 17. The lap 9 can thus be reversed whereby either of the two lapping surfaces, which may be of the same or different surface finish, may be operative. Retaining and trueing rings 26, having external gear teeth 26a, rest on the lap 9 and receive workpieces 27 which are pressed against the lap surface by circular weights 28 having hand knobs 28<SP>1</SP>. The rings 26 are maintained in circumferentially spaced relation by a central roller spacer 29 carried by the stem 24 and by roller stops 30 mounted on the housing 6. When corrective treatment of the surface of the lap is required, a pinion 31 is placed on the end of the stem 24 to mesh with the gear teeth 26a whereby the rings 26 are driven reversely as in Specification 947,142; the pinion 31 is removed during lapping. A bracket 33 secured to the member 7 carries an electric motor 34 driving, through a reducing gear-box 34<SP>1</SP> giving, e.g., 18 r.p.m., a container 36 projecting through an opening 32 in the member 7. The container holds light oil with abrasive particles in suspension. An openended helically wound tube 38 is mounted in the container concentrically therewith by baffle plates 39, preferably of spring metal, secured to the tube. The suspension is thus fed on to the lap 9, the baffle plates agitating the mixture to keep the abrasive particles in suspension. Used abrasive mixture passes from the lap 9 to the member 10 and is swept by a wiper bar 42 threaded into the hub 17 towards a drain spout 41.

Title: Process for the production of a hydroperoxide
Inventor: WEBSTER WILLIAM
IPC: C07C407/00
Filed: 1954-06-11
Abstract: The invention comprises 1 : 1 : 3-trimethylindan - 3 - hydroperoxide which is prepared by reacting molecular oxygen with 1 : 1 : 3-trimethylindane in the liquid phase at a temperature between about 50 DEG  and 130 DEG  C. and recovering the hydroperoxide produced from the reaction mixture.  The 1 : 1 : 3-trimethylindane may be anhydrous or emulsified with water. Small amounts of alkaline stabilizing agents such as alkali metal hydroxides, carbonates, bicarbonates and acetates and calcium oxide hydroxide or carbonate are preferably present.  The hydroperoxide may be extracted from the oxidation mixture with a concentrated aqueous solution of sodium hydroxide which is subsequently diluted with water or acidified, for example with carbon dioxide, to give the free hydroperoxide. Alternatively petroleum ether may be added to the oxidation mixture to precipitate the hydroperoxide.  In examples: (1) oxygen is passed into 1 : 1 : 3-trimethylindane at 90 DEG  C. in the presence of an aqueous sodium carbonate solution or calcium hydroxide; (2) air is passed into 1 : 1 : 3-trimethylindane at 120 DEG  C. in the presence of aqueous sodium hydroxide solution.

Abstract: 217,607. British Thomson-Houston Co., Ltd., (Assignees of Blume, L. F.). June 16, 1923, [Convention date]. Regulating transformers.-The voltage of a transformer is adjusted without interrupting its operation by dividing one of the winding into four sections, each of which is provided with a number of tappings, and connecting two of the sections of a number of parallel winding sections to the line, while the remaining sections are connected in parallel between the line sections. In the arrangement shown, for supplying lowvoltage current to an induction furnace from a high-voltage source, the secondary winding is divided into four sections 1 - - 4 which are distributed between sections of the primary winding and connected in parallel to the load circuit 5. The high-voltage primary winding comprises sections 6, 7, connected to the lines 10, 11, and intermediate sections 8, 9 in parallel, all four sections being symmetrically arranged to avoid high reactance. Each of the sections 6, 7 comprises two parallel groups of turns with tappings connected to switches 12, 13, and the remaining sections comprise single groups of turns with tappings connected to switches 14, 15, the latter being connected through circuit-breakers 16, 18 and reactances 17, 19 to the inner ends of the sections 6, 7. A simplified diagram of connections with the switch levers in the extreme positions, giving minimum voltage in the secondary winding, is shown in Fig. 2. When it is desired to adjust one of the switch levers, the corresponding circuit-breaker 16 or 18 is opened. The adjustments are so effected that the electrical balance between the different winding sections is disturbed as little as possible in order to avoid local circulating-currents in the sections 8, 9; such circulating currents as occur are limited by the reactances 17, 19, which are in series to the circulating currents but in parallel to the primary current. Additional pairs of tapped intermediate winding sections may be provided in order to increase the range of adjustment.
