Title: Improvements in cartridges for blasting, also applicable to the discharge of projectiles from guns
IPC: F42B3/087
Filed: 1938-04-14
Abstract: 514,383. Discharge apparatus. LEE, R. April 14, 1938, No. 11527. [Class 39 (i)] [Also in Groups XXI and XI] Relates to a cartridge for blasting or for the discharge of a projectile from a gun, the cartridge being of the type which is discharged through the expansion of a body of fluid confined therein. According to the invention, the heat necessary to the expansion of the confined body of fluid is produced by causing a substantially instantaneous, highly damped electric discharge from a condenser to occur within such confined body of fluid. As shown, the cartridge comprises a tubular metal casing 10 in which is confined a body of fluid 11 which may be a gas, such as hydrogen, or a liquid, such as water. An electrode 12 enters one end of the casing through an insulating bushing 13, a filament 14, e.g. of tungsten, being connected at one end to the electrode 12 and at the other to the remote end of the casing. If desired, both ends of the filament may be connected to insulated electrodes. When used for blasting the cartridge is inserted into a drill-hole 15 in the mass of material 16 to be disrupted and tamped in any usual manner whilst when applied to the discharge of a projectile from a gun, the cartridge is placed in the bore of the gun with the projectile in front thereof. A condenser 17, which may be in the form of a condenser blank, is connected to the casing 10 and electrode 12 by insulated conductors 18, 19 and is charged to a high voltage through direct current charging conductors 20, 21, the conductor 20 being grounded. A switch 22 controls the flow of the discharge current which is highly damped and ceases automatically. The current fuses the filament 14 and an arc discharge follows, the high voltage ionizing the hydrogen or, in the case of water, the latter dissociates at a high temperature yielding hydrogen which is rapidly expanded by the heat of the electric discharge to disrupt the casing 10 and the surrounding material in which the cartridge is placed. In some instances the filament may be dispensed with.

Title: Improvements in or relating to the treatment of glass fibres and articles formed therefrom
IPC: C03C25/26
Filed: 1961-03-29
Abstract: Glass fibres are lubricated by coating them with a continuous coating of a polymerizable lubricant comprising (a) aliphatic alcohol esters of epoxidized higher fatty acids, the esters having an oxirane content above 8.5, (b) polyamine resin precondensates of these epoxidized higher fatty acid esters with polyamines having at least 1 carbon atom between nitrogen atoms, (c) polyether resin precondensates prepared by the reaction of epoxidized higher fatty acids, epoxidized higher fatty acid esters, epoxidized higher fatty acid amides or epoxidized higher fatty alcohols with a strong Lewis acid catalyst or (d) polyester resin precondensates prepared by the reaction of epoxidized higher fatty acids or epoxidized higher fatty acid esters with polybasic acids, the higher fatty acids and higher fatty alcohols containing 10-30 carbon atoms, the fibres then being sized by partial polymerization of the lubricant and provided with a flexible, solvent and heat resistant coating by complete polymerization of the lubricant.  The lubricant as such or as an aqueous solution or emulsion is preferably applied to the fibres immediately after they are formed as they leave the orifice, partially cured, the fibres formed into a strand, woven into fabrics and completely cured, additional polymerizable treating agent being applied if desired.  Curing may be effected by heating if an epoxy curing agent is incorporated in the lubricant or by the use of an epoxy curing agent in the form of a gas, e.g. boron trifluoride. Epoxidized fatty materials which may provide the source of epoxy groups are animal, vegetable and marine triglycerides, e.g. epoxidized soybean oil, epoxidized safflower seed oil, epozidized linseed oil, epoxidized menhaden oil and epoxidized sardine oil which are epoxidized in an amount sufficient to provide two or more epoxy groups per molecule.  The polyamines used to prepare the lubricants are preferably lower alkylene polyamines, aryl polyamines or alicydic diamines. Suitable Lewis acid catelysts are boron trifluoride, zinc chloride, aluminium chloride, stannic chloride, silicon tetrachloride, sulphuric acid, perchloric acid and stannic oxide. The formation of the continuous coating of the lubricant on the fibres may be assisted by the incorporation of a spreading agent, e.g. a monoglyceride, in the lubricant.  Specifications 783,740, 788,381, 877,134, 877,136, 934,089 and 953,422 are referred to.

Abstract: 1,145,301. Transistor oscillator circuits. EVERSHED & VIGNOLES Ltd. 18 March, 1966 [22 March, 1965], No. 12047/65. Heading H3T. [Also in Divisions G3 and H2] An electric motor is energized with pulses of uniform length and amplitude, the interval between them and hence their frequency being controlled in response to the difference between a reference voltage V and motor back E.M.F. during the " off " periods. The control circuit comprises a multivibrator having PNP transistors VT1, VT2, and capacitors C1, C2, the discharge of C2, corresponding to the " off period," being controlled by NPN transistor VT5 which is associated with VT6 which has the control voltages applied to its base through R2, R3. Conduction of transistor VT2 effects conduction of a power transistor VT4 in series with the motor. The commutator ripple in the back E.M.F. is smoothed by the capacitor C2. A pair of diodes D1, D2 ensures cut-off of transistor VT6 while VT4 is conducting, and to prevent the circuit from switching on prematurely in response to the transient produced at the end of each pulse VT5 and VT6 are cut off by a pulse from the collector of VT1 when that switches on, for a time determined by C3, R4. Alternatively to the D.C. motor shown, one phase of a two-phase A.C. motor may be controlled in like manner, the other phase being continuously energized. A diode D3 protects VT5, VT6 from the pulse applied via C3.
