Title: Improved method of attrition and mill for effecting same
IPC: B02C19/00
Filed: 1941-01-14
Abstract: 546,474. Pulverizing by attrition; centrifugal separators. EAGLE PENCIL CO. Jan. 14, 1941, No. 524. Convention date, Jan. 15, 1940. [Classes 23 and' 59] The stock to be pulverized passes from a hopper 23 down a conduit 21 into a chamber 12 whence it is sucked into a tube C by two compressed air, gas or steam ejectors I and D. The tube C is kept substantially full of stock, and pulverizing is effected by relative movement between the centre of the stock stream and the sides thereof which make contact with the tube. The pulverized stock passes through a curved tube 32 which enters tangentially an expansion chamber 17, and the heavier particles fall into the chamber 12 to be re-pulverized while the lighter particles are levitated off through a pipe 34. From pipe 34 the lighter particles pass through successive separators 36, 41, 47. By attaching the pipe 34 to the inlet 50 or inlet 49 the proportion of fines obtained will be smaller or greater respectively. The pipe C may be in the form of a helix.

Title: Rolling mills horizontal-roll change
Inventor: SWALLOW REGINALD DENNIS
IPC: B21B31/10
Filed: 1962-01-08
Abstract: 1,008,944. Rolling. DAVY & UNITED ENGINEERING CO. Ltd. March 4, 1963 [Jan. 8, 1962; Jan. 15, 1962], Nos. 734/62 and 1440/62. Heading B3M. A method of changing a pair of horizontal rolls of a rolling mill which is provided with guides for the rolls as they are extracted, includes the steps of extracting the rolls from the mill on to the upper and lower decks of a first mobile roll change unit, removing the unit from the mill vicinity, and replacing it with a second, similar unit carrying a second pair of rolls, the rolls then being inserted in the mill. The vertical rolls of a mill may be exchanged at the same time as the horizontal ones. In operation, a roll change unit 43, Fig. 2 of the first Provisional Specification is rigidly coupled to a mill 10 having horizontal rolls 15 and 16 supported on slideways 19 and 26, and hydraulically operated, hooked pistons 57 withdraw the rolls on to sliding surfaces of the unit 43. A motor-driven locomotive unit 40 houses piston assemblies 55 and is coupled to the unit 43. The locomotive unit 40 moves the unit 43 to a section of track 91 where a piston assembly 93, Fig. 1, shifts the now uncoupled unit 43 sideways. A second roll change unit carrying replacement rolls is simultaneously aligned with the unit 40, the replacement rolls being moved towards the mill where they are inserted. The slideways of the roll change units are slightly inclined to assist in roll changing, and the units themselves may be self-propelled in order to obviate the locomotive unit. An mill 97, Fig. 1, has a roll changing arrangement similar to that of the mill 10. The sliding table 89 may be replaced by a roller-table, by tracks, or by a turntable, and the unit 43 can have retractable wheels, mounted transversely to the wheels running on the tracks 36, for sideways movement. The locomotive unit can have, instead of motor-driven wheels, a motordriven sprocket engaging with a toothed track. After removing the horizontal rolls, a bridge at the foot of the roll change unit is pivoted vertically and the two vertical rolls are mounted on a platform beneath the bridge. Piston and cylinder assemblies are used to manipulate the rolls and the chocks on to the carriage, the left-hand vertical roll assembly being shown in Fig. 2 of the second Provisional Specification after being moved across the roll stand but before being lowered on to the right-hand assembly. A separate trolley which runs on inclined rails on the rail change unit may alternatively be used for the vertical rolls.

Abstract: 996,863. Boring earth &c. R. F. BAUER, and H. STRATTON. Jan. 9, 1963, No. 995/63. Heading E1F. Casing 15 is set in a well 19 in a formation 20 underlying a body of water 17, and a marine conductor 60 is guided to be connected to the casing by a drill pipe 41 extending from a vessel 18 to the well. The casing is fixed to a base 14 having buoyancy tanks 14A, and is releasably attached to blowout preventers 44, and a receiver 45. The base, casing, blowout preventers and receiver assembly is floated into the position shown in Fig. 1 beneath the cellar 38 of the vessel. The drill pipe, having collars 42 and under-reamer 43, is run through the casing and rotated to start the well, seawater being pumped through the pipe to clear drillings. When the well reaches a sufficient depth to receive the casing the assembly is lowered down the pipe so that the base rests on the formation. Where the depth of water is less than the length of the casing, the base alone is positioned beneath the cellar, casing is run into the base, and the base and casing are lowered until the base rests on the formation. The well is drilled sufficient to receive all the casing, the casing is lowered a few feet into the well, the drill pipe is withdrawn from the casing, and the remainder of the casing is lowered by means of the drill pipe which is gripped by the blowout preventers which finally rest on the base. When in place in the well the casing is cemented. To enable the drilling of the well to be completed with circulation of drilling mud the conductor is fixed to the receiver, the conductor being lowered over the drill pipe which is held by the preventers. The upper end of the conductor has a buoyancy chamber 88, a sliding section 108 which carries the mud return line 118, and a telescopic section 94 which permits the vessel to be moved quickly to abandon the well temporarily. The well may also be abandoned by removing the conductor and the upper part of the drill pipe, operating the preventers to grip the pipe extending from the well, and attaching a buoy to the extending pipe. In a modified method of temporarily abandoning the well, the preventers are dispensed with and the top of the pipe carries a plug which engages the receiver (Fig. 7, not shown). In a further method the pipe is removed from the well the casing being sealed by a plug to which the buoy is attached (Fig. 6, not shown). In a modified method (Figs. 8-11, not shown) of locating the assembly at the formation, the base is supported in the cellar, the casing is run through the base until just clear of the formation, the drilling equipment is run through the casing, the well is drilled for a sufficient depth to receive the casing, the equipment is removed, the casing is lowered and fixed to the base, the receiver and preventers are fitted, the receiver is releasable connected to the drill pipe, and the assembly is lowered until the base seats on the formation. Reference has been directed by the Comptroller to Specification 873,480.

Title: Production of light guide
Inventor: AMANO MICHIYUKI
IPC: G02F1/361
Filed: 1989-01-05
Abstract: PURPOSE:To easily produce the core-clad type light guide parts by heating a high-polymer material which is changed in refractive index or both of the refractive index and optical nonlinear constant by electrification at the glass transition temp. or above to the glass transition temp. or above, then electrifying only the prescribed part to form the core and cooling the same. CONSTITUTION:A compd. having the structure expressed by formula I is used as the high-polymer material (sample). This sample 1 is heated to the temp., for example, 70 deg.C, above the glass transition temp. The charge flowing in from a corona discharger runs off to the outside through the conductive layer of a mask 3 in the part where the mask 2 is mounted if the sample 1 is electrified by a corona discharger. As a result, only the part where the mask 2 is not mounted is electrified and is oriented and polarized. The sample 1 is then slowly cooled in the electrified state down to room temp. and finally the mask 2 is removed. The need for mounting electrodes to the waveguide surface at the time of production by orientation and polarization treatments is eliminated in this way and the easy production of the long-side light guide is possible. Various light guide elements, optical nonlinear elements, etc., are, therefore, easily produced.

Abstract: PURPOSE:To eliminate a rout including a backup part by the backup information obtained by communication between cars on road, display the shortest route, and allow the search of an optimum route even in a traffic backup. CONSTITUTION:A route searching part 52 searches, for example, a link 0-1-2 as an optimum route (first route candidate), a link 3-4-5 as a second route candidate, a link 0-6-4-5 as third route candidate, and the like up to a eighth route candidate, and stores them in a route candidate storing part 53. A backup presence judging part 54 judges the presence of a traffic backup by the information of a VIES receiver. In case of NO, the optimum route is displayed, and in case of YES, initialization is conducted with an ordinal (i) as 1 to judge whether a backup is present in the link of the i-th candidate. In case of YES, 1 is added to the candidate ordinal (i), the same judgment is conducted. Namely, the delay is present in any one of the link 0-2 in the first candidate, and the link 3-5 in the second candidate. In case of NO, the i-th candidate is displayed. Thus, by adding the dynamic information of backup, an optimum route capable of arriving at a target position can be determined.
