Title: An improved method of forming apertures in the walls of pressure vessels and improved tools suitable for carrying out the method
Inventor: STOCKMAN SIDNEY JAMES
IPC: B23K7/00
Filed: 1957-11-01
Abstract: 875,520. Cutting by fusion; portable boring-machines. BABCOCK & WILCOX Ltd. Oct. 31, 1958 [Nov. 1, 1957], No. 34165/57. Class 83 (3) and 83 (4). An accurately positioned aperture 142 is formed or finish machined in the wall 1 of a pressure vessel, particularly for a nuclear reactor, by a rotatable cutting tool 105 mounted for universal adjustment on a support frame 7 attached to the wall 1, and a sighting device is provided for aligning the tool. A pilot hole 3 is first flame cut in the wall and the frame 7 is attached to the shell exterior by welds at the feet 13. The frame carries a tool head 19 mounted for angular and lateral adjustment in two directions whereby the correct position of the tool axis can be determined by a telescopic sighting device 191, Fig. 11 (not shown), or 191X, Fig. 12 (not shown), removably mounted on the tool head. The sighting device is then removed and a tool shaft 109 is passed into the head. This shaft which is rotated through gearing in the head by a geared electric motor 96, mounts at its lower end a radial arm 107 carrying an oxy-acetylene torch 105 and at its upper end a radial arm 132 carrying a tracer head 133 co-operating with a template 103 pivotally mounted on pins 101. A wire rope 113 passing over a winch drum 117 driven by a D.C. shunt-wound geared motor 119 supports the weight of the shaft 109. The tracer head has a spring-loaded plunger 139, Fig. 5, engaging the template surface 103A and co-operating with reversing contacts supplying the motor armature AW whereby as the torch 105 rotates the tracer head is maintained at a substantially constant distance from the template surface. A solenoid brake 141 is applied when the motor is de-energized. The shaft 109 is then removed, a second frame is attached to the inside of the shell, the alignment of the tool head is checked by the telescopic sighting device and a boring bar 151, Fig. 6, is inserted in the tool head. This bar carries a boring tool 175 in a holder 155 which is traversed vertically by a lead screw 177 rotating with the boring bar and carrying at its lower end a star wheel 183, Fig. 9 (not shown) engaging on each revolution a fixed peg. The boring bar is rotated by a pneumatic motor on the shaft end 73A. Separate tools are used for up and down cutting movements.

Abstract: 511,010. Ball mills. KENNEDY, J. E. Nov. 24, 1938, No. 34188. [Class 59] In a tube mill in which a drive shaft is connected to trunnion opening by spider arms, the arms extend tangentially to and from the hub in the direction of rotation and transmit rotary movement edgewise through the arms. As shown, a drum 5 provided with inlet trunnion 8 and outlet trunnion 9 is mounted on bearings 10, 11 and is driven axially by a motor M through speed reduction gear and flexible coupling 36, 37.

Class 106(5) Free-piston apparatus for delivering fluid in predetermined quantities comprises supply and delivery passages placed alternately in communication with opposite sides of the piston by a manually - operated slide valve, the quantity of fluid delivered being varied by altering the piston stroke by means of an adjustable stop. The piston comprises a centre-plate 20 between cup - washers 19, 21 and a clamping plate 22 screwed on to a bush 17, the lower face of the bush contacting the end of an externallyscrewed member 24 whereby the stroke of the piston may be adjusted to vary the quantity of fluid delivered. After adjustment, the member 24 may be secured by a lock-nut 9 screwed against the outer face of the lower cylinder head 12. The cylinder 10 is held between the upper- and lower heads 11, 12 by bolts 13, a tube 35 being inserted between the heads to provide communication between passages formed in the heads. A piston guide-rod 15 is screwed into the upper cylinder head 11 and extends through packings 23 in the bush 17 and in the interior of the threaded member 24, which may be provided with a leakage draining passage. A valve block 38, secured to the upper cylinder head 11, has three right-angled passages 39, 40, 41, Fig. 4, formed therein and leading from a side face of the block to ports 45, 46, 47 in the bottom face, communicating respectively with the space above the piston, via passages formed in the cylinder head, the outlet port 31, and the space below the piston. A slide valve 49 mounted on the end of an arm 50 of a bell-crank lever pivoted at 51 puts the outlet port 43 on the block 38 alternately into communication with the spaces above and below the piston as the crank is manually operated by a lever 72 and rod 59 to move the valve between stops 53, 54, pressure within the valve cover 77 causing the fluid to flow alternatively via ports 45, 47 and passages 39, 41 in the valve block to opposite sides of the piston. A spring-loaded ball 63 engages detents on the rod 59 to ensure full-stroke movement of the valve 49.

Cylinder machines; tripping arrangements.- A travelling cylinder printing machine comprises a base 23, at least a portion thereof forming a plane which defines a print bed adapted to support a printing means, e.g. plate (20) (Fig. 1), a carriage 36 mounted for reciprocating travel across the print bed, a platen assembly, e.g. including an L-shaped bracket 39, 41, mounted for pivotal movement, e.g. about rod 44, relative to the carriage and also including a platen roller 43 rotatably mounted, e.g. about shaft 42 at one end of the bracket, movable means, e.g. yoke-shaped bar 46, extending parallel to the path of travel by the carriage for rooking the platen assembly about its pivot point 44 to elevate the platen roller from the print bed when rocked in one direction and to lower the platen roller toward the print bed when rocked in the opposite direction. As shown in solid lines, Fig. 3, the gate 46 is shifted to the right thus rocking the platen assembly by way of shaft 45 about rod 44 and seating rod 44 in a detent 49 on cam 48 until bracket bar 41 abuts adjustable screw 57. This is the printing position and the pressure of roller 43 on avil 24 is adjustable by screw 57. Manual movement of carriage 37 via handle 37 in the Y direction performs the imprinting function, carriage 37 being guided by bearings (29), (31), (32), (33), (Fig. 2), travelling in tracks on guide rails (25), (26), (Fig. 1). When carriage 37 reaches its extreme right-hand position protruding end 53 of yoke 46 engages member (60), (Fig. 1), shifting the yoke to the left and simultaneously rocking bracket 38 about rod 44 to the position shown dotted where rod 44 is engaged in a detent (51, Fig. 2) on the opposite side of cam 48, thus raising the roller 43 from the print bed, and allowing the carriage to be returned across the print bed to its start position where the yoke engages member 59 (Fig. 1) causing the roller to be lowered once again.

Title: Process for preparing light magnesium hydroxide
IPC: C01F5/14
Filed: 1946-11-23
Abstract: Light magnesium hydroxide in powder form is produced by mixing moist magnesium hydroxide precipitated from aqueous solution with a hydroxylic liquid, e.g. water and/or methyl, ethyl, isopropyl, &c., alcohol, mixture of alcohols or methylated spirits, heating the mixture to within say 50 DEG  C. above or below the critical temperature, and reducing the pressure while avoiding a fall in temperature of more than 30 DEG  C.  The magnesium hydroxide employed may be obtained from solutions of magnesium salts and strong alkali or ammonia, or from sea water and lime or dolomitic lime. 10-30 parts hydroxylic liquid to one part magnesium hydroxide (reckoned on the dry material), are suitable.  The process may be effected batch-wise, or the suspension may be pumped intermittently into a heated pressure vessel, and drawn intermittently into a second heated pressure vessel in which the pressure is released; alternatively, it may be pumped into a vessel or through a coil wherein it is heated to near the critical temperature, the pressure being maintained by regulated withdrawal into a vessel at atmospheric pressure and heated to a temperature near the critical temperature of the liquid.
