Title: Single reel magnetic tape unit
IPC: G11B23/107
Filed: 1975-09-05
Abstract: 1480868 Recording and playback INTERNATIONAL BUSINESS MACHINES CORP 5 Sept 1975 [20 Dec 1974] 36726/75 Heading G5R [Also in Division B8] A single reel magnetic tape unit comprises a cartridge support 46, Fig. 2, so that the hub 204 of reel 200 can be rotated, via hub 208, by drive motor 84, a vacuum column for producing a gap 250 between adjacent turns and a stepping motor 28 for inserting a head 32 into the gap. The unit may be operated in a rapid access mode (Fig. 4, not shown) whereby the tape is rapidly transferred from the outer bale 136 of the reel to the inner bale 134-approximately 17 layers per revolution of the reel. The outer bale is kept stationary by a roller 60 and a friction layer 50, and the inner bale is rotated clockwise or anticlockwise. The unit may also be operated in a sequential mode (Fig. 5, not shown) for reading or writing, one layer being transferred from one bale to the other for each revolution of the reel. A light sensor 138 senses the presence of the gap and the force transducer 144 ensures that the force on the head is at a given level by comparing its output signal with a reference signal. Wedge-shaped horizontal and vertical means 18, 44, co-operate to position the head assembly 30. The means 18 is driven by a stepping motor 36. The vacuum ports 66 pull reel flange (202, Fig. 7, not shown) in an axial direction which enables a magnet (210A) to be moved away from its keeper (210B) and the latter locks the reel in place when the cartridge is removed from the unit.

Title: Improvements in or relating to circuits for cathode-ray tubes
Inventor: HALL ROBERT JAMES
IPC: H04N3/26
Filed: 1963-09-18
Abstract: 1,024,637. Cathode-ray tube circuits. ELECTRONIC TUBES Ltd. Sept. 18, 1964 [Sept. 18, 1963], No. 36757/63. Heading H4T. In a cathode ray tube circuit comprising a first potentiometer VR2 controlling the potential applied to the brightness controlling grid of the tubo, and a second potentiometer VR1 controlling the potential applied to the focusing anode A2, the first and second potentiometers are ganged together, so that defocusing of the tube spot which would otherwise occur on adjustment of the spot brightens by manipulation of the first potentiometer is substantially automatically corrected by the resultant adjustment of the second potentiometer. Since the law relating the focusing voltage required to give the best focus with a given brightness control voltage, is non-linear, Fig. 2 (not shown), the output of potentiometer VR2 is made correspondingly non-linear by the addition of resistors R3, R4 and VR5. Resistor VR3 adjusts the voltage across potentiometer VR1; VR6 adjusts the voltage across potentiometers VR2 to be equal to the cut-off grid voltage of the tube, and resistor VR4 adjusts the voltage difference between the focusing anode and the brightness controlling grid. Neons N1 and N2 stabilize the voltage across potentiometer VR2. Examples of component values are given, and the setting up procedure of the circuit is given. Fig. 4 (not shown) illustrates the modifications necessary when time-base bright-up pulses are applied to the grid.

Abstract: 368,471. Starting and ignition circuits. BRETTELL, F. G., 75, Colmore Row, Birmingham.-(Motor Devices, Inc. ; 540, North Michigan Avenue, Chicago, U.S.A.) Jan. 27, 1931, No. 2614. [Classes 7 (ii) and 7 (v).] A key-switch 27 first closes the circuit of an electric starter, then the ignition circuit, and finally opens the starter circuit while leaving the ignition circuit closed. Primary and secondary windings of an ignition coil are arranged in a casing 1 adjacent to an insulating partition 15 in which are mounted segmental contacts 18, 21, 19, 20. Arcuate contacts 38, 39, 40 project from an insulating disc 30 integral with the rotatable lock-barrel 26. Axially projecting from the disc 30 are a ratchet disc with three teeth 41a and a step-by-step rotative member 43 having fingers which coact with the segment 21 and with arcuate recesses 22, 23 in the partition 15. Terminals 45 . . 49, at the opposite end of the casing 1 are connected as shown in Fig. 6. With the switch in the " off " position, the finger 38 is adjacent to but out of contact with the top end of contact 18, the fingers 38, 39 adjoin the lower ends of contacts 19, 20, two of the fingers 43 are engaged with the shoulders 24, 25 of the recesses 22, 23 and the third finger 43 will be to the left of segment 21. The first movement of the key causes engagement of contacts 18, 19, 21. The solenoid 76 is energized, contacts 75 are closed and the motor 68 rotates. The pinion 69 engages flywheel pinion 61 and turns the engine shaft. Further key rotation closes contacts 20, 40 and completes the ignition circuit. As the switch reaches full " on " position the contact 21 is disengaged, but the circuit through the motor 68 remains completed, due to the engagement of a flange 71 with a blade 72, until the engine speeds up sufficiently to overrun the motor and cause the pinion leg and flange 71 to slide out of engagement with the wheel 60 and blade 72 respectively. Should the engine stop it cannot be restarted by the motor until the switch has been turned back to " off " position. During this reversal, the member 42 remains inoperative due to the obstructing shoulders 24, 25. The contacts 71, 72 may be omitted if a definite stop is ensured in the movement from "off" to " on " position. This may be effected by means of a spring-pressed ball 36 engaging a recess in the member 30.

Title: Solvent extraction process and apparatus therefor
IPC: C13B10/10
Filed: 1963-09-25
Abstract: In a process and apparatus, Figs. 1 and 4, for the continuous, countercurrent extraction or diffusion of a soluble substance such as sugar from subdivided solid material, such as sugar-beet or sugar-cane, the material is fed, as by a travelling belt 40 and a distribution scroll 42, into an annular trough 5 having inner and outer cylindrical walls 22 and a flat, e.g. perforated, draining base 24.  The trough 5 is supported on rollers 15 and mounted on a slowly rotating central shaft 2.  The material is thus distributed around the trough as a bed having a substantially horizontal upper surface. Extracting liquid, e.g. a mixture of fresh water, from a pipe 121, and water expressed from spent material delivered through a pipe 122, is circulated by a system including distributers S to S16 and S17, pumps P1 to P17 and tanks T1 to T17, so that it makes progressively a series of downward percolations through the rotating bed and the base 24.  The resulting solution or extract is collected in a tank T18 beneath the material-receiving part of the trough 5.  Spent material is removed from part of the trough above the tank T1, e.g. upwardly, as by mechanism including an elevator 52 and a scroll conveyer 55, or downwardly, as by mechanism described in relation to Fig. 6 (not shown).  The distributers S to S16 each comprise a radial trough 90 provided with outlet openings 117 for distributing the extracting liquid.  Substantially the same quantity of liquid is collected in each of the tanks T1 to T17.  The distributing troughs 90 are secured to inner and outer, circular, roller-mounted tracks, which can be turned around the shaft 2, so that all the troughs 90 can be moved together over and around the annular trough 5. <PICT:1066791/C6-C7/1> <PICT:1066791/C6-C7/2> Chlorine, formaldehyde or sulphur dioxide may be used in the process to control the growth of bacteria.
