Title: Improvements in or relating to water compatible explosive
IPC: C06B47/14
Filed: 1960-03-21
Abstract: 893,590. Explosive compositions; blasting. HERCULES POWDER CO. March 21, 1960 [March 20, 1959], No. 10011/60. Classes 9(2) and 68(1). A water-compatible explosive comprises 20 to 80%, by weight, of an inorganic oxygensupplying salt comprising ammonium nitrate in at least a major proportion, 8 to 70% of a nitrocellulose material which is fibrous nitrocellulose, a densified nitrocellulose, or a smokeless powder, and 5 to 45%, of water. Preferably the salt consists of ammonium nitrate only but it may be replaced in minor part by sodium nitrate, magnesium nitrate, calcium nitrate, potassium nitrate, barium nitrate, sodium perchlorate, ammonium perchlorate, calcium perchlorate or magnesium perchlorate. The viscosity of the mix may be increased by adding 0.5 to 5.0% of a gelforming agent such as guar gum, methyl cellulose or water-swellable starches. The compositions are insensitive to commercial blasting caps but may be detonated by booster charges of PETN or RDX. Preferably the composition is poured or pumped into a borehole or inserted in plastic bags which are slit when the hole is filled. In mixing the ingredients they may be heated to 70‹C. to remove entrained air and sufficient water is added to bring the bulk density of the mass to 1.0.

Title: Regulating means for use in liquid fuel supply systems
Filed: 1947-04-16
Abstract: 633,565. liquid-fuel burners. LUCAS, Ltd., J., and IFIELD, R. J. April 16, 1947, No. 10065. [Class 75 (i)] [Also in Group XXVI and XXIX] Regulation means for the return flow of fuel from the spill-type burner of a jet-propulsion turbine comprises a valve controlling-the inlet to a duct in the return flow system and responsive to the difference between the blower-air pressure and the returned-fuel pressure, and another valve controlling a byepass outlet from the duct and responsive to the blower-air pressure. In Fig. 3, which shows the fuel circulating system, a pump 33 delivers fuel from a tank 35 to the burner nozzle 34 and the fuel return flow from the nozzle is connected at 30 to a fuel regulator 32 comprising the duct having the valve controlled inlet and the valve controlled byepass outlet. The normal outlet from the duct is connected through an adjustable choke 36 to the inlet of the pump and the byepass outlet from the duct is connected through a connection 22 to the inlet of the pump. Blower air is conveyed to the regulator through a connection 29. The regulator 32 is shown in Fig. 1 and comprises a valve member 24 mounted on a flexible diaphragm 25 and co-operating with the inlet end of a duct 15 carrying the return flow of fuel from the burner nozzle. The diaphragm 25 divides a chamber in the fuel regulator into a compartment 26 connected to the oil return flow system and a compartment 27 connected to the blower-air system of the burner. The outlet end of the duct 15 communicates through other regulating means, such as a manually adjustable choke, with the inlet side of the burner fuel pump. A byepass outlet 16 in the duct 15 is controlled by a valve member 17 connected by means of a U-shaped member 19 to a second flexible diaphragm 4 which divides another chamber in the fuel regulator into two compartments 2, 3. The upper compartment 2 is connected to the blower-air system and contains an evacuated elastic capsule 10 which is secured to the flexible diaphragm 4 and is adjusted by a supporting bolt 11 rotatable in the cover of the regulator. The lower compartment 3 contains the duct 15 and is connected to the inlet side of the burner fuel pump. A perforated spring disc 20 is attached to the lower end of the U-shaped member 19 to guide the valve member 17. During normal working conditions in the combustion chamber the byepass outlet 16 is closed and the inlet to the duct 15 is open, since the pressure of the returned fuel in the compartment 26 is greater than the pressure of the blower-air in the compartment 27. If, however, the supply of fuel to the burner is suddenly reduced, as by manual means, the blower-air pressure closes the valve 24 to interrupt the return flow and prevent extinction of the flame. Should the maximum speed of the turbine be exceeded the increased blower-air pressure causes the diaphragm 4 to open the byepass outlet 16 thereby reducing the oil discharge through the burner nozzle.

Title: Improvements in or relating to the production of alkenyl benzenes
Inventor: CAPP CLIFFORD WILLIAM
IPC: B01J23/16
Filed: 1963-03-14
Abstract: An alkenyl benzene is produced from a mono- or di-alkyl benzene having at least two carbon atoms in each alkyl side chain by vapour phase dehydrogenation with molecular oxygen in the presence of an oxidation catalyst comprising an oxide of vanadium, while maintaining a molar ratio of oxygen to alkyl benzene of less than 10 : 1. Suitable catalysts comprise ternary compounds of vanadium, another metal and oxygen, e.g. vanadates of tin, cobalt, chromium, manganese, tungsten, zinc, lead and bismuth, uranyl vanadate, and the vanadyl compounds chromate, manate and tungstate; they may also contain other metal oxides or salts and may be supported on silica, alumina or a diatomaceous earth. Dehydrogenation of a reaction mixture containing 5-17% by vol. alkyl benzene, 2.5-17% by vol. oxygen and, if desired, an inert gaseous diluent such as N2 or steam may be effected in 0.1 to 30 secs. at 200-600 DEG  C., the alkenyl benzene being recovered, e.g. by solvent extraction or liquefaction.  Preferably the molar ratio oxygen : alkyl benzene is less than 3 : 1.  By this process styrene may be produced from ethyl benzene, a -ethyl styrene or divinylbenzene from diethylbenzene, and a -methyl styrene from isopropyl benzene.  In an example, a catalyst containing vanadium, manganese and oxygen was used to convert ethyl benzene in a gaseous mixture of 8.2% ethylbenzene, 4.6% oxygen, 87.2% nitrogen (all by volume) to styrene at a temperature of 350 DEG  C.
