Title: Magneto-optic transducing systems
IPC: G11B11/105
Filed: 1970-11-13
Abstract: 1316448 Magneto-optic transducing INTERNATIONAL BUSINESS MACHINES CORP 13 Nov 1970 [15 Dec 1969] 54024/70 Heading G5R A magneto-optic system is employed to read out one of a plurality of superimposed recordings on a magnetic storage medium. In the arrangement shown in Fig. 1, the magnetic storage medium 10 is positioned close to a magnetic film 12 formed on a face 26 of a prism 24, and biasing magnetic field sources 13, 14 are arranged to produce fields in the plane of the film 12 such that only one set of recordings is effectively transferred to the film as a consequence of the proximity between the medium 10 and the film 12. Thus, with orthogonal recordings as in Fig. 3A, either set may be selectively transferred to film 12, as shown in Figs. 3B, 3C. The read out from the detecting system 29 (Fig. 1) thus depends only on which recording is transferred to film 12.

Abstract: 1443348 Mounting and dismounting bearings MORGAN CONSTRUCTION CO 29 Nov 1973 [18 Dec 1972] 55425/73 Heading F2U A bearing 20 has a retaining force applied by a nut 70 when the latter is rotated upon a screwthreaded ring 68 which moves rearwardly along a keyway to a stop 78, Fig. 3, disposed in a groove 18, Fig. 2, a locking member 100 being attachable to the nut, as by bolts 112, to prevent rotation of the nut on the ring after assembly. The shaft end 14 has a flat 90 to permit insertion of the key 88 between the shaft and screwthreaded ring 68 and the locking member is L-shaped and arcuate and provided with an end plate 114 for retaining the key. The stop 78 is formed of two arcuate sections hinged together at the top and provided with handles 82. The bearing 20 shown is a roll neck bearing which is keyed to and tapered to fit the roll neck 4 for rotation in a stationary chock 26 lined with bush 28. Rotation of the roll causes rotation of the bearing 20, a sleeve ring 34 and an inner race 40 of a thrust bearing, the sleeve ring being keyed to both the bearing and race. With the locking member 100 removed, the nut 70 can be rotated to move the race 40 and sleeve ring 34 forwardly to cause a flange 36 to press on the bearing 20. To dismount the bearing 20, the nut is rotated to move rearwardly into contact with a flange 76 on the chock assembly to move the assembly into contact with a flange 46 on the bearing. The locking member 100 can only be attached when aligned with the groove 18 to ensure correct tightening of the nut 70 during the mounting operation.

Abstract: 1430439 Pneumatic conveyers A MEARS & CO Ltd 29 Nov 1974 [30 Nov 1973] 55747/73 Heading B8A A hopper for the reception of granular material comprises a conveying line along which material is carried by compressed air and a diaphragm in a wall of the hopper, pressure of material on which causes closure of a valve supplying the compressed air. In Fig. 2, material enters hopper 1 by pipeline 9, carried therealong by air entering line 9 at open end 22, from line 20. A diaphragm 10 in the wall of hopper 1 is arranged to operate control valve 19 such that when the pressure of the material on the diaphragm exceeds a predetermined amount, valve 25 operates to close the line 20 at port 27, thus preventing passage of compressed air to line 9 and so stopping conveyance of material. The carrying air is filtered off at 5, and hopper 1 may be arranged above a second hopper. As pressure on diaphragm 10 decreases due to emptying of hopper 1, line 20 is opened again and conveyance of material recommences.

Abstract: 1,273,250. Welding by pressure. ALLWOOD, SEARLE & TIMNEY Ltd. 16 Nov., 1970 [19 Nov., 1969], No. 56525/69. Heading B3R. Friction welding apparatus comprises work supports 8, 11, the support 11 being adjustable between a friction position in which it follows a path which is at least substantially circular but does not rotate relatively to the second support and a welding position in which it does not move relatively to the second support. The motion of the work support is derived from drive means including a rotor (e.g. crank portion 28 of shaft 16, Fig. 2) the axis (32) of which on rotation generates a cone, and a follower (e.g. bearing 37) which may be located at the apex of this cone or spaced from it, the former position producing no motion of the follower and the spaced position giving rise to a circular but non-rotary movement of the follower and hence also of the work support. In the embodiment described in relation to Figs. 1, 2, a pair of parallel shafts 16 having cranked portions 28, 29, 30 are driven from a common drive shaft 22 to effect the desired motion of a carriage 13 supporting the work support 11. Axial movement of the shafts 16 may be effected by hydraulic cylinder and piston unit 25 to adjust the apparatus between the friction and welding positions and this movement is possible while rotation of the shafts 16 continues. The crank portions 29 of the shafts 16 provide for dynamic counterbalancing of the motion of the carriage 13, by means of a counterweight 41. The provision of a flywheel in the drive and of means for mounting a plurality of workpieces for simultaneous welding are envisaged. In a second embodiment (Figs. 3-5, not shown) adjustment from the friction to the welding position is effected by altering the position of the apex of the cone without altering the relative longitudinal positions of the rotor and follower.

The cracking of the light fraction is at 950‹ to 1100‹ F. and at a conversion of at least 80%, to maintain the pour point of the light gas oil product at 10‹ F. or less, while the cracking of the heavy fraction is at 900‹ to 1050‹ F. and a conversion of 60 to 85%. This enables the ratio of naphtha to light cycle gas oil to be varied with seasonal variations in demand by varying the conversion of the heavy fraction, while keeping the pour point of the light cycle gas oil low enough for use as a furnace oil. Reference has been directed by the Comptroller to Specification 1,167,254.

A fuze for a projectile comprises a firing pin 28, Fig. 2, having a cylindrical lateral extension 31 and a portion 33 of reduced diameter, and an L-shaped sealing ring 37 compressed against the wall of the bore 30 in which the firing pin is movable, the thickness of the ring in the uncompressed state being greater than the gap between the wall of the bore 30 and the extension 31. The sealing ring is made of P.V.C. or rubber. A fusible ring 39 formed with air passages 40 retains the firing pin in a safe position. In another embodiment (Fig. 3, not shown) the fusible ring is formed with air passages in each end face and is separated from the sealing ring by a metal ring. In a further embodiment (Fig. 4, not shown) the sealing ring is compressed between the bore wall and a metal ring separating the fusible ring and the sealing ring. The sealing ring is bent into an L-shape by allowing the ring to overlap the extension 31 as indicated in chain lines and then drawing the housing 29 over the extension. The lower end of the firing pin holds a centrifugal rotor 13, Fig. 1, in a safe position. Upon launching a projectile fitted with the fuze, the fusible ring 39, Fig. 2, is melted by air flowing through the passages 40, and the firing pin, thereby freed, is lifted by the rotor as it rotates under the action of centrifugal force. The firing pin is driven against a detonator 14 either at impact or when the force of a spring 20 overcomes the centrifugal force acting on balls 26, which ever is the earlier.
