Abstract: 1,054,751. Magnetic information storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 27, 1964 [March 29, 1963], No. 8100/64. Heading H3B. [Also in Division H1] In a magnetic thin film store in which two conductors extend transversely to each other the area of film adjacent the conductors' intersections forms an individual storage cell and the width of each conductor is not greater than the " remaining domains " produced in the film by an incomplete switching process. If a gradually increasing external field H is applied in the direction # to an anisotropic thin film the magnetization of the latter is as shown in Figs. 5 a to 5 d, the vectors rotating until H = Hp, Fig. 4, when partial rotational switching occurs and stripshaped domains appear with the magnetization of alternate strips in different directions. Since a stray field energy with a strong local effect is linked with the suddenly formed domain walls and prevents further rotational switching, then if before wall moving occurs Fig. 5d, the external field is switched-off the stray field energy prevents the magnetization returning to its initial conditions and " remaining domains " of opposite magnetization directions are left, Fig. 5e. In the store of Fig. 11 (not shown), orthogonal sets of strip drive lines 12, 13 are arranged above a magnetic film 11. The areas 19 of the film 11 underlying the intersections of the drive lines form the storage cells and are of smaller area than the " remaining domains " which are formed by incomplete switching and reducing the external field to zero. Since the storage cells are smaller than the domains only the anisotropy of the film and the drive field are effective so that the magnetization of each cell can switch coherently. The memory cells may be rectangular, Fig. 13 (not shown), and the drive lines may be connected in parallel, Figs. 14, 15 (not shown).

Abstract: 1,232,242. Tape rolls. MINNESOTA MINING & MFG. CO. 28 June, 1968 [30 June, 1967], No. 31162/68. Heading B8M. [Also in Division F2] A roll 18 of film material which has a stretchy flexible nature, e.g. pressure-sensitive adhesive tape 16 wound upon a hollow cylindrical core is characterized in that the core is formed of discrete arcuate segments 10, 12, 14 which are held together to form the cylinder by the radially compressive forces of the tape. The ends of the arcuate segments may be formed to intermesh or may be hingedly connected together. The core may be formed of 2 to 6 segments. The expanded core is placed on an expandible mandrel which comprises arcuate elements around a solid core, the elements having protrusions with inclined surfaces which engage notches with similarly inclined surfaces on the solid core, so that axial movement of the segments relative to the core causes the arcuate elements to ride up the inclined surfaces and thus the circumference of the mandrel increases. Movement in the opposite axial direction collapses the mandrel for removal and collapse of the tape core.

Abstract: 1,234,418. Controlling clutches. C. CAPPA. 22 Aug., 1968, No. 40153/68. Heading F2L. A vehicle clutch is automatically disengaged by a vacuum-operated servomotor 17 on gear shift and, below a predetermined vehicle speed, an accelerator release and on application of the brakes. The clutch can also be disengaged manually by the usual clutch pedal 10. The servomotor 17 has a chamber 19 connected to a vacuum reservoir 25 on energization of a solenoid valve 24 to shift a piston 16 to the left and disengage the clutch by way of a flexible cable 14 or an hydraulic telemotor system. The control circuit of the valve 24 includes a centrifugal switch 29 which opens at a vehicle speed of 25 kilometres per hour, an accelerator controlled switch 26 opening on depression of the accelerator, an ignition switch 27 closed when the ignition is " on", a switch 74 closed on application of the brakes, a microswitch 68 which is opened on depression of the accelerator pedal, and a switch 72 closed on grasping the gear lever. Thus on starting, the ignition switch 27 is closed and the valve 24 energized so that the clutch is disengaged by vacuum in the chamber 19. On depression of the accelerator, the microswitch 68 is opened and the clutch engages under the action of the clutch engaging spring 69. Release of the accelerator below 25 kilometres per hour, i.e. when the centrifugal switch 29 is closed, energizes the valve 24 to disengage the clutch. Above this speed the switch 29 is open and the clutch remains engaged. Actuation of the brakes closes the switch 74 and if the switch 29 is also closed the clutch disengages. Operation of the gear shift lever closes switch 72 to disengage the clutch. The rate of clutch engagement is controlled by controlling venting of a servo chamber 18 behind the servo piston. Venting is controlled by three valves: a solenoid valve 21 which is closed when energized and is de-energized when the centrifugal switch 29 is open to give rapid re-engagement on completion of gear shift above 25 kilometres per hour, a valve 23 having a plurality of ports successively opened as the accelerator is depressed, and a valve 70 having a sleeve abutting the servo casing and co-operating with a vent port in the piston-rod. Thus assuming the valves 21, 23 to be closed, when the chamber 19 is connected to atmosphere the piston will move rightwardly until the valve 70 closes to give slipping clutch engagement, this position being set by adjusting the valve sleeve 70 by means of a screw-threaded collar thereon which abuts the casing. Air is admitted to the chamber 18 on clutch disengagement by a oneway valve 20.

Abstract: 1,238,014. Cutting by fusion. H. R. MORGAN. 29 July, 1968 [30 June, 1967], No. 30273/67. Heading B3V. Means for generating relative linear motion for tube-end cutting apparatus wherein a cutter and a tube 31 to be cut have such relative motion parallel to the tube-axis and also have relative rotary motion, comprises a crank 5 on crankshaft 1 rotated in synchronism with the relative rotation and in bearings 2, 2A mounted on a bed plate 4, a saddle 18 in bearings parallel to the crank-shaft's axis and supporting a transverse platform 16 which carries a cross-slide 14 supporting a shaft 11A having an arm 10 connected to the crank 5 by a universal swivel connection 9. Thus, rotation of the crank-shaft reciprocates the saddle, which may support a flame-cutter, or this may be on a saddle-extension 18A. The angle of the cutter may be varied during cutting, as described in Specifications 1,013,738 and 1,111,900. A spring 33 or a weighted chain &c., acts on the saddle to hold the ball 9 in its socket. A clamp 17, securing the platform 16 to the saddle, permits angular adjustment of the platform. The throw of the crank 6 and the effective length of the arm 10 also are adjustable for different tube-sizes. A chuck 30 may rotate the workpiece 31 and is driven by a countershaft 25 rotated by chains 21, 23 which are driven manually through a wormgear. A multiplying or dividing device may be included in the saddle-drive.

Abstract: 1,238,595. Vibration dampers. CLARK EQUIPMENT CO. 3 June, 1969 [7 June, 1968], No. 28032/69. Heading F2S. In a vehicle having a super-structure, such as a stacker truck 9 running on rails 21, the superstructure tends to oscillate when the vehicle is decelerated. To damp such oscillations the invention provides a damping device 49 including a rotary electric generator 50 whose electromagnetic resistance to rotation is selectively variable. The generator is belt-driven from a roller 61 running on a fixed guide rail 30 and it is arranged that the motor's resistance to rotation is increased whenever the structure as a whole is decelerated. Fig. 3 (not shown) depicts a suitable control circuit. When a switch in the control panel 11 of Fig. 1 is operated to decelerate the structure it also varies the resistance to rotation of the generator in one or more of three ways, viz. (a) it increases the current in a stator winding of the generator; (b) it energizes such a winding, the winding being unenergized when the structure is moving at its normal transit speed; (c) it varies the electrical resistance in series with the rotor coils of the generator.

Pans 38, 40 and 42 are positioned beneath and collect sand from a sand blasting room and convey the sand by reciprocation thereof by respective cams 92, 94 and 96 to discharge it on to a vibrating conveyer 80 operated by cam 120. In Fig. 2, cam 94 engages a roller 112 mounted on a support 108 secured at 118 to the pan 40 so that rotation of the cam moves the pan leftwards and then frees it to swing under gravity so that the support 108 engages a stop 99 to jerk the cam and cause conveyance. In Fig. 5, the sand falls through a grating 101 and on to the pans 40 and 42, the pans being supported by pivoted levers 48, 50 which are protected from the sand by a resilient member 68. Barrier members 70, 71 and 72, 73 aid in deflecting the sand and further resilient members (77), Fig. 6 (not shown) provide seals for the sand. A screw conveyer (130) can be used in place of the conveyer (80), Figs. 13, 14 (not shown). In Figs. 15, 16 (not shown) hydraulic cylinders are used in place of the cams for moving the pans.
