Title: Improvements in or relating to blasting methods
IPC: F42D1/00
Filed: 1946-05-16
Abstract: 640,988. Blasting ; blasting caps. ATLAS POWDER CO. Feb. 27, 1947, No. 5687. Convention date, May 16, 1946. [Classes 9 (i) and 68 (i)] In multiple bore hole blasting wherein a row of at least three generally aligned charged holes is detonated to break away a face and form a new face therebehind, the charges in at least three successively adjacent bore holes in the row are initiated at times separated by from 2 to 150 (preferably 20 to 75) milliseconds and preferably within approximately 300 milliseconds of the time of actuation of the detonation initiator in the first firing of these adjacent holes. There may be more than one row of holes, and each row may be generally parallel to the face to be broken away, with or without a row of holes at right-angles to such face. The firing-time separation may be obtained by the use of electric blasting caps having different firing times or connected to different circuits which are energized at separate times, or by particular arrangements of detonating fuses. The Specification contains examples of suitable caps and firing arrangements. The Figure shows a bore hole 20 loaded with a main explosive charge 22 and upper explosive charges 26, 30 separated by gravel stemmings 24, 28, 32. The main charge 22 is initiated by two similar electric blasting caps 34, 36, whilst the upper charges 26, 30 are initiated from the main charge 22 by detonating fuse 50. Specification 640,514 is referred to.

Abstract: 672,384. Electrically-tripped switches. ELECTRICAL APPARATUS CO., Ltd., and BARBOUR, R. H. Nov. 29, 1950. [March 7, 1950] No. 5750/50. Class 38 (v). An electromagnetically-trippable switch has an armature 8 pivoted at 7 and normally biassed by a spring 10 to the position shown where a contact arm 17 pivoted at 22 is held against the end 16 of the armature by two springs 18, 19 acting on the arm 17 on opposite sides of its pivot. The springs 18, 19 carry contacts which are thus normally bridged by the arm 17, the circuit being broken when the arm 17 is released on attraction of the armature, the springs swinging the arm counter-clockwise so that it tilts an indicator 26, pivoted at 24, to show that the switch has tripped. The switch may have, and as shown has, a contact 31 which is engaged by a projection 33 on the arm 17 when the latter is in the tripped position. The spring 10 is attached to a member 12 which is adjustable by means of a screw 13 for current setting.

Filed: 1960-02-18
Abstract: 891,433. Electromagnetic switches. DONLAN ELECTRONICS Inc. Feb. 18, 1960 [April 2, 1959], No. 5865/60. Class 38 (5). [Also in Group XL (b)] A waveguide switch comprises a block 10 of triangular section having within it three waveguide passages intersecting at 120 degrees and an obturating vane 27 mounted on a rotatable shaft 28. The shaft is normally biased to a position in which the vane closes one of the passages 19, 20 and is actuated to open this passage and close the other one by means of a solenoid 43, Fig. 3. The shaft 28 is coupled by means of toothed wheels 31, 34 to an insulated shaft 38 which carries a solenoid plunger 35 and a helical biasing spring 46. Rotary motion is imparted to the plunger 35 and shaft 38 by means of a spiral groove 36 which engages lands 37 on the solenoid body. When the solenoid is energized, the plunger rises from its lower (biased) position and shaft 38 engages a reed-type contact arm 39 which normally forms a short-circuit around a resistor 42 arranged in series with the solenoid. The resistor limits the current in the solenoid to a value which is just sufficient to hold the plunger in the upper position.

[Also in Group XXVI] In combustion equipment of a gas turbine engine, the outlet passage part of a flame tube comprises spaced concentric walls and a plurality of turbine inlet nozzle guide vanes extend between and are carried by the concentric walls, the flame tube together with the nozzle guide vanes constituting a unit which is removable from the engine as a whole, or in which all the parts are connected together in a permanent manner. The combustion equipment shown in Fig. 4 comprises outer and inner air casing walls 61, 62 forming an annular space therebetween in which a number, say seven; tubular flame tubes 14 are disposed in circular formation. The downstream end of each flame tube changes from circular cross-section to a segment of an annulus having outer and inner walls 86, 28 respectively and radially-disposed side walls 87, 88 secured thereto by welding. Lugs 95, 96 are formed integrally with the outer wall segment 86 and are bored to receive bolts 43 by which adjacent flame tubes are secured together. The inlet nozzle guide vanes 45 are hollow being formed of sheet metal and are mounted in correspondingly shaped apertures formed in the walls 86, 28. Relatively cool air passes from the space between the outer air casing wall 61 and the flame tubes through the hollow guide vanes 45 to an annular space formed between the inner wall 28 and a U- section ring 115 formed by segments secured to the radially inner surface of the wall 28, the air escaping through ports 121 into the working fluid stream. The wall 86 is formed as a separate casing and is secured to the outer arcuate wall 12 of the flame tube by welding. The wall 86 is formed at its downstream end with a flange 102 which is provided with dogs 110 which are engaged in recesses formed in the extension 105 of the turbine casing. The upstream end of the flame tube is supported by the fuel injector in a manner allowing for angular or endwise movements; swirl vanes 20, 18 and 75 are provided in the inlets for primary air.

Title: Dyeing textile materials of polymers and co-polymers of acrylonitrile and asymmetric dicyanethylene
IPC: C09B44/04
Filed: 1958-02-28
Abstract: Dyestuff compositions contain as dyestuff components dis- and tris-azo dyestuffs, free from sulphonic acid and carboxylic acid groups and having at least one externally bound primary, secondary or tertiaryamino group or quaternary ammonium group.  By 'externally bound' groups is meant such groups which are not attached to an aromatic nucleus but are attached to a terminal radical of the dyestuff molecule, and do not form part of a carboxylic acid amide or sulphonic acid amide group.  Textile materials consisting of polymers and copolymers of acrylonitrile or asymmetric dicyanethylene may be dyed or printed with these compositions.  The dyestuff may be used in acid or neutral solution or suspension, and dispersing agents may be added to the dyebath.  In an example, 3 gms. polyacrylonitrile fibre are dyed in an aqueous dyebath containing 1% of a dyestuff of formula:-  <FORM:0849994/IV (c)/1> and 3% by weight acetic acid, (based on the fibre weight) at a liquor to goods ratio of 40 : 1. The material is introduced at 40 DEG -50 DEG C., the bath raised to the boil in 20-30 mins. and boiled for 1 hour.  An orange dyeing is obtained.  In another example, a polyacrylonitrile fabric is printed with a paste consisting of 30 gms. of the dyestuff obtained from 2 mols. of diazotised 1-amino -2- chloro-nitrobenzene and 1 mol. of the chloride of 1-(b  trimethylammonium ethyl) amino -5- hydroxy-naphthalene together with 50 gms thiodiglycol, 30 gms. cyclohexanol, 50 gms., 30% by weight acetic acid, 280 gms. water, 30 gms. 50% zinc nitrate, 30 gms. printing oil (a mixture of aliphatic hydrocarbons), and 50 gms. resoranol.  The print is steamed at 100 DEG -103 DEG C. for 10-30 mins. and then soaped at 40 DEG -60 DEG C. and dried.  A greenish-black print with good fastness is obtained.

IPC: F16H15/10
Filed: 1925-03-10
Abstract: 251,730. Stevenson, D. March 10, 1925. Variable-speed friction gearing comprises an intermediate or idle face disc C adapted to connect driving and driven roller members a, b which disc is so mounted in a movable bracket D that it will take up an inclined position when disengaged. Thus when the disc C is moved into engagement, it contacts with the driven member b first, and so avoids wearing flats on that member. The gearing is of the type in which the speed is varied by moving the roller b across the intermediate disc, and in which members a and b carry clutch members for direct driving. The tilting of the bracket D is effected by a slot connection d with a fixed pin E, and by a spring F.
