Title: Improvements in and relating to bombs and projectiles for use in aerial warfare
IPC: F42B12/66
Filed: 1937-06-09
Abstract: 498,595. Projectiles. MOTLEY, L. June 9, 1937, Nos. 15977 and 18628. [Class 9 (i)] A bomb or projectile for attacking hostile aircraft comprises a number of units coupled by cable and adapted to be separated from each other in the air, increased tension of the coupling cable arising, e.g. by contact with an aircraft causing at least one of the units to explode. The projectile may be fired from a mortar 7 and may comprise a frictionally held cap 1 housing a parachute 2 connected by a bolt 29 passing through wadding 28 to a container 3 which is connected by a coiled cable 8 to a second container 4, the containers accommodating explosive charges 5, 6. Separating charges 9, 10 are located between the parachute and the upper container, and between the containers, respectively. The cable 8 may be coupled with one or both containers by a detonating device which is actuated by excessive tension on the cable. In one form, the cable 8, Fig. 3, is coupled to a lever 11 having a pin to strike the detonator 12, the lever being held in inoperative position by a pin 23 which shears under excessive load. In another form, the cable is coupled to a lever 11, Fig. 4, which is held inoperative by a spring 24 until the cable is subjected to abnormal strain, in which case the lever swings and is snapped to operative position by the spring 24 to strike the detonator 12. The projectile is mounted in a cartridge case 13 which accommodates the propellant charge 14. A time fuze 18 connects the charge 14 with the separating charge 10, and an instantaneous fuze 19 is provided between the separating charges 9, 10. When the projectile is fired, the containers 3, 4, after a given time interval, are separated by the firing of the charge 10 and substantially at the same instant the charge 9 blows off the cap 1 and allows the parachute to open. The container 4 falls to the extent permitted by the cable 8 and the apparatus falls as a whole under the restraint of the parachute, constituting an aerial mine. Impact on the cable, e.g. by hostile aircraft, increases the tension on the cable and fires the explosive charges 5, 6. The projectile may be fired from the ground or may be dropped or fired from an aircraft ; when it is to be dropped, the cartridge case is omitted and the fuze 18 is ignited directly either electrically or by a blow. Specification 498,599 is referred to, as describing and claiming means for automatically ejecting the cartridge case from the muzzle of the mortar after the firing of the projectile.

Title: Catalyst carrier
IPC: B01J35/10
Filed: 1961-05-08
Abstract: An alumina catalyst carrier contains 0.02-1% of boron oxide and has a porous volume due to pores of diameter from 0.1-8 microns of 5-20 cm.3 per 100 g., a specific surface less than 0.5 m.2/g., the carrier having been prepared by calcination at 1600-1800 DEG  C. of a mixture of active alumina of specific area at least 20 m.2/g. together with 25 to 400% of its weight of a -alumina and the necessary proportion of boron oxide.  The calcination may be effected in a tube furnace along which the alumina is passed in which case the quantity of boron oxide added to the initial charge is substantially equivalent to that present in the final product.  Alternatively, if a static mass is heated in a furnace then the initial mixture should preferably contain from 0.1 to 5% of boron oxide.  According to a typical example aluminum oxide of which not more than 80% is larger than 20 microns, the remainder being less than 60 microns is mixed with an equivalent quantity of active aluminium oxide obtained by pulverizing aluminium oxide trihydrate in a current of a hot gaseous mixture of air and hydrocarbons at about 700 DEG  C. 0.05% of boric anhydride is added to the mixture which is then kneaded with water and granulated into 3 mm. balls which are dried at 1100 DEG  C. before calcining at 1700 DEG  C. for thirty minutes.  The addition of boron oxide increases the porous volume and decreases the surface.  The carriers obtained may be impregnated with metallic salts.

Title: Improvements in and relating to the production of hydrogen and gas mixtures containing hydrogen
IPC: C01B3/34
Filed: 1928-06-08
Abstract: 296,428. Epner, C. Sept. 2, IMP, [Comvention date]. Cyclic hydrocarbons; aldehydes; ketoues.- Hydrogen or gases containing it together with thin liquid hydrocarbons or viscous lubricating oils are obtained by treating hydrocarbon-containing gages such as coke oven gas or distillation gas. with a silent electric discharge produced by high-tension alternating electric field of high frequency. The liquid products are mixtures of cyclic saturated. and unsaturated hydrocarbons, and where the gases treated contain carbon monoxide or dioxide, aldehydic or ketonic products are obtained. The process may be carried out at normal or elevated temperature. If the gases produced are to be used under pressure, they are first treated by compression, or with oi]s or absorbents such as active carbon or silica gel to remove the less volatile substances present. The process may be carried out in a device of the Siemens ozonized type in which the earthed outer electrode may be flowing water and the high-tension electrode concentrated sulphuric acid which may be provided with a water coil for cooling. For higher-temperature liquid metals or alloys may be used as electrodes. The gases may be passed through several of the devices in series. The gases may, in otherforms of the process, be passed through plate condensers or between concentric tubes of dielectric material covered with conducting foil. An example is given in the Specification in which a discharge of 20,000 volts and 1-0,000 cycles per second derived from a high-frequency machine is employed in a Siemens ozonizer of 4 em. outer diameter having a discharge chamber 15 cm. long and a gap of 2 cm.. the gas flow being 2 litres per hour.
