Title: Improvements in and relating to aerial mines and projectiles
IPC: F41H11/04
Filed: 1937-04-20
Abstract: 493,312. Aerial mines. BICKEL, E. April 20, 1937, No. 11247. [Classes 9 (i) and9(ii)] An air mine for destroying aircraft is stored in a projectile and discharged from a gun, the mine being released from the projectile at a predetermined point in the trajectory. The mine comprises a nose 1 which constitutes also the nose of the projectile, and a body 2 carrying an explosive charge and, if desired, an incendiary charge 3, pivoted arms 10 lying along the body, when in the projectile casing 6, and being surrounded by a coil of wire &c. 9 which is coupled to a parachute 8. A time fuze in the nose may fire a charge 7 in the base, through a central tube 4, so as to expel the mine from the casing 6, the parachute 8 then opening and uncoiling the wire from the mine. The coils may be glued or soldered together sufficiently to retard the running off of the wire &c. When all the wire is unwound, the arms 10 move to radial positions in contact with detonators 11 so that on the fouling of the line 9 by an aircraft, and impact occurring on the upper side of any of the arms 10, the mine is exploded. If, however, the mine comes to earth without having been exploded in the air the arms 10 will only move upwardly. thus ensuring that the mine is not exploded on contact with the ground.

Filed: 1974-03-14
Abstract: 1424939 Brake boosters ALFRED TEVES GmbH 14 March 1974 [14 March 1973 31 Aug 1973] 11330/74 Heading F2F  A booster assembly for an hydraulic braking system comprises in a housing 1 a master cylinder and piston 3, a brake-pedal-operable member projecting from the housing, a control unit including an axially-movable valve spool 23 and control casing 17 coupled to the pedaloperable member, and a travel simulator piston 12 allowing the pedal-operable member to travel an amount conducive to " feel " during boosted braking, wherein the master cylinder piston 3 is separated from the control unit by a first pressure chamber 21 which is connectible upon brake actuation to a supply of pressurized fluid, and wherein when pressurized fluid is not supplied to the first chamber 21 the master cylinder piston and control unit are mechanically linked by an axially movable connection composed of several parts to drive the piston 3 and actuate the brakes upon failure of the presurrized fluid supply. On actuation of the brake pedal 5 an accumulator charging valve is moved to open position and pressure medium supplied to the control casing. By further shifting of spool 23 the connection between chamber 21 and a chamber 18 is separated and pressure chambers 21 and 11 are no longer connected to reservoir 29 and pressure in chamber 11 moves piston 3 away from a pistonrod 15 of piston 12. The pressure increase in chamber 21 causes casing 17 to be displaced and the spool 23 follows its movement whereby the pedal travel required for brake actuation is obtained. If the brake circuit assigned to working chamber 6 fails master cylinder piston 3 moves to the left until it touches the bottom of chamber 6 and further actuation of pedal 5 causes a further pressure build-up in chamber 11  to apply pressure to brakes 13, 14 via a port 27.

Inventor: BATES JAMES JOHN
IPC: H01R39/46
Filed: 1965-03-19
Abstract: 1,079,792. Improving commutation in dynamo - electric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 7, 1966 [March 19, 1965; July 29, 1965; Nov. 4, 1965], Nos. 11755/65, 32571/65 and 46890/65. Heading H2A. Mechanical commutation is improved by dividing the brushes into two parts 16, 17 and 18, 19, each of which is connected to the terminal 10 or 11 through a thyristor T 1 , T 2 , T 3  or T 4 . The commutator segments 1, 2, 3 . . . are so spaced that at least one, and sometimes both, brush-parts make contact. Each thyristor is triggered when its brush-part makes contact and is extinguished by a reverse voltage V 1  induced either by commutating poles 9, by angular displacement of the brushes, or by graded air-gaps (Figs. 7-10, not shown), or by A.C. voltage induced by generator or transformer action in coils 7, 8 linking the partbrushes, or by A.C. injected into the armature. As shown, a single commutator is used, but alternate armature leads may be connected to separate commutators with mutually staggered segments engaged by the part-brushes respectively (Fig. 2, not shown). The part-brushes are replaced, in this form, by two brushes 73, 74 and 75, 76, so spaced that they nearly cover the internal between commutator segments. Triggering pulses are fed from a gate pulse generator 86, through a controlling commutator 77 to the thyristors. The commutator may be separately enclosed and flexibly connected to the machine shaft. An inverted D.C. machine, i.e. with rotating poles and fixed commutators, is described (Fig. 3, not shown), the brushes and thyristors being carried on the shaft and fed via slip-rings. The stationary armature winding may be liquid cooled. A generator-motor set is described in which the voltage induced by the generator interpoles serves to extinguish the motor thyristors. The interpoles are shunt excited. Disc-type commutators gripped between brushes on spring-loaded arms, are described (Figs. 5 and 6, not shown). Flat D.C. motors are described (Figs. 7-10, not shown) in which the two commutators are mounted on either side of the rotor disc which carries the commutated pole-windings.

Title: Improved method of preparing finely comminuted oxides
IPC: C01B13/36
Filed: 1939-04-21
Abstract: 527,855. Colloidal sols, silicon boron aluminium, titanium and zirconium oxides. CORNING GLASS WORKS. April 21, 1939, No. 12059. Convention date, May 14, 1938. [Classes 1 (i), 1 (ii) and 1 (iii)] Finely comminuted oxides are produced by dissolving a hydrolizable compound in a non- aqueous liquid medium consisting of or containing a liquid in which water is substantially insoluble or immiscible, introducing water by adding a stoichiometric quantity thereof to the solution and thereafter filtering out the product. The water may be dissolved in a nonaqueous medium and mixed with the hydrolizable compound solution, the concentrations of the water and hydrolizable compound in their respective solvents determining the size and thus the filtering properties of the resultant product. Examples of hydrolizable compounds are silicon halides, ethyl silicate, titanium tetrachloride, aluminium chloride, zirconium chloride and methyl borate. A suitable water insoluble liquid medium is benzene while suitable non aqueous liquid media are glacial acetic acid and acetone. While it is possible to add the water dissolved in the miscible medium to the hydrolizable compound dissolved in the water immiscible medium it is preferable to use an equal mixture of the two media to dissolve both reactants the liquid being reusable without modification other than replacing losses, A preferable concentration is one gram molecule in 500 c.c. which in the case of silicon tetrachloride would require two gram molecules of water dissolved or suspended in 500 c.c. of medium to complete the reaction. Very dilute solutions produce unfilterable precipitates. To economise in solvent ice may be added to the solution of the hydrolizable compound in a water immiscible medium. It is stated that part of the precipitate produced is unfilterable. If desired mixtures of oxides may be produced by using a solution containing hydrolizable compounds of two elements.
