Abstract: 1285694 Automatic control of magnetic fields PERKIN-ELMER Ltd 25 Nov 1969 [10 Sept 1968] 42928/68 Heading G3R [Also in Division G1] A magnet system, for example that used in a nuclear magnetic resonance spectrometer, is stabilized against short-term flux disturbances by the provision of a pick-up coil 4A, 4B, a main bucking-out winding 5A, 5B and an auxiliary bucking-out winding 6A, 6B arranged as shown in Fig.1, the signal generated by the coil 4A, 4B being applied to a high-gain amplifier 7 whose output is fed to the windings 5A, 5B, 6A, 6B in such a manner that the auxiliary winding receives a fraction of the energization supplied to the main winding to complement the stabilizing action thereof. This fraction is determined by the setting of a variable resistor 10 which may shunt the winding 6A, 6B if a series connection of the two windings replaces the parallel one shown. The spacing of the two windings is chosen so that the main winding provides a major part of the stabilization and the auxiliary winding retains its operational identity. Construction and arrangement of the windings is discussed together with the design values of the circuit components 7, 8, 9, 10. If the system is used in a N.M.R. spectrometer, the effectiveness of stabilization corresponding to the setting of the variable resistor 10 may be tested by introducing a deliberate magnetic disturbance around the system and measuring the shift in the position at which a given resonance line is observed.

Abstract: 1,061,024. Control of D.C. motors. BAILEY METER CO. Nov. 1, 1963 [Nov. 1, 1962], No. 43207/63. Heading H2J. [Also in Divisions G3 and H3] In a control system for a turboalternator, Fig. 1, the load on a turbine 5 is determined by a pressure sensitive transducer 37 in the first stage, and compared with a demand signal 11 at a summing junction 13 to derive an error signal 17. The error signal is fed to an input winding of a magnetic amplifier 19 to control the energization of the appropriate field of a motor 9 to position a linkage 22 of a primary valve 23 of a speed governor 7 which, through a main pilot valve 27, positions a steam admission valve 35. The magnetic amplifier has a second input winding which is energized by the output of a unijunction switch 20 which is cyclically operated to block the magnetic amplifier to error signals of less than a predetermined level. The unijunction switch. Fig. 2, incorporates a power supply section consisting of a full-wave rectifier bridge 41, 43, 45, 47, a smoothing filter 49, 53 and a Zener diode stabilizing arrangement 51, 55. A multi-vibrator section comprises a unijunction transistor 57, biased by resistors 61, 59, with feedback applied through resistors 63,. 65 and a capacitor 67. A switch section comprises a transistor 69, with inhibit coils 71, 73 of the magnetic amplifier and current adjusting resistors 75, 77 in the collector circuit. During full conduction of transistor 69 the negative side of capacitor 67 is clamped at the base potential of this transistor which is near zero. The capacitor then charges through resistors 61, 59 until the potential on the positive side reaches the firing voltage of the unijunction transistor 57. The transistor 57 then conducts causing the emitter voltage to fall, which in turn, through the capacitor 67, causes transistor 69 to become non-conductive. The capacitor 67 charges again, through resistors 63, 65, until transistor 69 is fully-conductive and forwardly biased. The capacitor then discharges through the emitter-base circuits of the transistors 57, 69. When the positive side of the capacitor 67 has discharged to about 2 volts the unijunction transistor 57 is cut-off. The capacitor 67 now recharges through the resistors 59, 61 and the cycle recommences.

Title: Alignment of members to electron beams
IPC: H01J37/304
Filed: 1971-09-16
Abstract: 1361804 Positioning electron beams WESTINGHOUSE ELECTRIC CORP 16 Sept 1971 [6 Oct 1970] 43302/71 Heading H4D A plurality of areas on the surface of a silicon semi-conductor wafer 32, Fig. 1, are to be electron beam worked by respective electron beams. Apparatus is provided for exactly and repeatedly aligning the electron beams on the areas to be worked. Two alignment electron beams, produced by the photocathode 40 producing the working beams are roughly aligned with respective conductive areas 72, 74, Fig. 2, having the same cross-sections as the beams and positioned in diametrically opposed hollows 64, 68 on the peripheral surface of the wafer 32. X and Y deflection circuits in coils 56 and 58 move the beams until maximum current is detected for the areas 72, 74 whence exact alignment is achieved. The photo-cathode and wafer and their mounting means are enclosed in a vacuum chamber. Ultra-violet light from source 50 is used to illuminate the photocathode comprising a quartz base 40, ultraviolet opaque areas 42 and electron emitting areas 44 of palladium or gold exposed to the ultra-violet. The electron beam emitted by areas 44 are focused on the wafer by coils 54 and - 10,000 V. bias 46. The alignment beam may be two selected ones of these beams, or source 50 may be covered apart from two areas, or a light guide may convey the ultra-violet from a source to an area 44. Wafer 52 is roughly positioned by stops 61, 62, 63, 65. The alignment beam 92, Fig. 4, for area 72 is first used for X direction beam deflection wherein the D.C. component in the output 87, Fig. 8, varies as shown at Fig. 4B, the maximum at O indicating when alignment in the X-direction has been achieved. A more exact measurement is enabled by imposing a small component of circular oscillation on the beam deflection by means of orthogonal sinusoids from oscillator 108 fed to the amplitude modulators 126, 130 in the deflection feed paths. Such oscillations give rise to an A.C. component in the output 87, having a phase reversal at the alignment point. This is detected by phase detector 106. The procedure is repeated for deflection in the Y-direction. The deflection correction signals are produced by integrating the outputs of the detector and are then modulated. The beam for area 74 is now used and the same method used to swing the beam in an arc about beam 92 until a maximum output of area 74 is detected and the alignment beams are angularly aligned. Detection of alignment causes detector 156 to stop oscillator 108 and, via delay 166, causes the main or working electron beams to be included. Various shapes of areas 72, 74 and corresponding crosssection of beams are shown, Figs. 5, 6, 7 (all not shown) together with the variation of their output.

Abstract: 1330165 Cathode-ray storage tube MASSACHUSETTS INSTITUTE OF TECHNOLOGY 15 Sept 1970 [18 Sept 1969] 43899/70 Heading G4C [Also in Division H1] The target of a cathode ray storage tube comprises conductive layers 4 and 10, Fig. 16, between which is a semi-conductor layer 1, on which is deposited an insulating layer 2. The target is preferably used to store binary data, and if the semi-conductor is P-type the layer 4 should be biased positively to record a one and should preferably be biased negatively to record a zero; the former results in a charge being stored in the depletion layer of the semiconductor material, whereas the latter causes no charge storage and removes any previously stored charge. During the reading operation the bias may be zero or positive, and the beam current may be reduced to prevent erasure; a separate beam may be used for reading. Alternatively data may be re-recorded immediately after reading, as shown in Fig. 16 where the output on line 98 is fed back to the input circuits 101 and 102 which control the bias applied to layer 4. The normal inputs for "write one", "write zero", and "read" are supplied on lines 85-87 respectively from a computer (not shown) and input address signals are gated at 83, 84 by the write 1 read signals and converted into suitable voltages for feeding to the beam deflection plates 76.

Abstract: 1,078,336. Converting. ALLMNNA SVENSKA ELEKTRISKA A.B. Oct. 28, 1964 [Oct. 31, 1963], No. 43919/64. Heading H2F. In a polyphase converter station in which the constituent converters are operated in mutually phase-displaced groups, the total power output is regulated so as to be approximately the same for each group in order to reduce the number of harmonics in the A.C. side of the converter. Fig. 3 shows a chain of converters 1-6 between D.C. lines 7 and 8. The converter transformers have their inputs connected in parallel to an A.C. network as at 9 and their outputs provide star and delta phase groups Y, D. Under normal conditions, all the converters 1-6 provide equal voltages and carry equal currents. If a converter in one group is by-passed under fault conditions, the power balance between the groups may be restored by tap-changing on the converter transformers so as to increase the output voltage of the converters in the affected group and reduce the output voltage of the converters in the other group. Alternatively, the balance may be restored by drawing currents from D.C. lines 10 and 11 (which may connect with an adjacent converter station) and a centre-tapped earth line (Fig. 2, not shown), such that the 'total current carried by the converters of the affected group is increased with respect to the total current of the other group. Tap-changing may also be used to compensate for any current unbalance caused by an adjacent converter station. In a further embodiment (Fig. 4, not shown), two or more chains of converters may be connected in parallel. If a converter in one chain becomes by-passed, the voltage in a parallel chain may be lowered to restore the power balance either by disconnecting a converter in the parallel chain or by grid control of the converters in the parallel chain. Fig. 5 (not shown), illustrates an arrangement for co-ordinating the control of the current and voltage of a converter station having two groups of constituent converters, in which each converter is provided with a grid control system (2) which determines the control angle of the converter valve group (1), a tap selector (4) and a watt-meter (5). The total power for the two groups of converters is determined by summation units (7 and 8) and compared by a device (9). The output from device (9) is fed as an error signal to the grid control system (2) and the tap selector (4). In the embodiments described, A.C. machines or generators may be connected to Y-D pairs of converters.

Heading B3M. In a ten-high rolling mill with alternative working rolls 1 and 15, for cold rolling or hot rolling strip respectively, intermediate, driven, backing rolls 2 and 3 are mounted in chocks 6 and 7 which are radially guided in bores 10 and 11 of backing roll shafts 4a and 5a. The shafts support backing rolls 19 (Fig. 2, not shown), for engagement with the rolls 2 and 3. Rockers 12 and 13, shrunk on to the shafts 4a and 5a and similarly formed with bores, are rotatable about roll axes 4b and 5b to vary the position of the rolls 2 and 3 so that they each lie on a line joining a work roll to a respective backing roll 4 or 5. This rotation is effected by cylinders 21 and 22 which slide within a fixed common cylinder 20 and embrace arms 12a and 13a of the rockers. Hand wheels 36 and 37 move the cylinders 21 and 22 axially, while a chamber 33 which is supplied with pressure fluid urges the cylinders apart and prevents backlash in the adjustment. The rolls 2 and 3 are additionally adjusted to lie slightly off the lines joining the roll centres in order to oppose forces due to strip tension and driving torque. Thus, for each reversal in a rolling programme the rolls 2 and 3 are adjusted to lie on the opposite sides of these lines. Pistons 23-26 within the cylinders 21 and 22 abut the arms 12a and 13a and are movable through a small distance 5 to effect this adjustment. Hydraulic conduits 28-31 supply fluid to opposite sides of the pistons 23-26.
