IPC: H01F10/00
Abstract: 1,095,440. Magnetic storage devices. STANDARD TELEPHONES & CABLES Ltd. Oct. 14, 1966, No. 45948/66. Heading H1T. [Also in Division H3] A magnetic storage device comprises three thin film regions two of which regions have the information stored therein and a third region, situated between the two regions, in which the information stored in the two regions is temporarily stored for read out. A thin film of isotropic magnetic material is deposited over four posts 4 of a base-plate of ferrite material which form closed magnetic circuits with storage regions 1, 3 of the film, the region 2 forming the interrogation region of the store. To write information into the store the wordclear write conductor, which passes through all the slots 7 of a row of the storage devices, is first pulsed with a clearing pulse, Fig. 5 (not shown) to switch all the devices in the row to the " 0 " condition dotted flux path in Fig. 3. The clearing pulse is then followed by a word pulse of opposite polarity coincidently with an information pulse on the digit write conductor 9 which passes through all the devices making up one column of a rectangular array. If the information pulse is positive it combines with the word pulse to switch the storage regions 1, 3 to the " 1 " condition, solid lines in Fig. 3, whereas if it is negative the total field strength is reduced and the regions 1 to 3 remain in the " 0" condition. In order to read information out a negative transfer pulse is first applied to interrogate conductor 11 which writes into the interrogation region 2 a remanent condition representing the stored information in the regions 1, 3. The combined effect of the transfer pulse and the fringe fields in the region 2 of the device due to the flux in the regions 1, 3 is to write into the interrogation region a remanent magnetization having a diagonal component, Figs. 4, 6 (not shown). If a " 1 " is stored the remanent magnetization is directed upwards to the right and if a " 0 " is stored is directed upwards to the left. Following the transfer pulse a read pulse is applied to the interrogate conductor 11 of positive polarity and twice the amplitude of the transfer pulse which switches the remanent magnetization of region 2, the polarity of the induced pulse in the digit-write conductor 9 indicating whether a " 1 " or " 0 " was stored. Since the fringe fields due to the regions 1, 3 remain unchanged a second transfer pulse will produce a remanent magnetization in the region 2 the same as the first transfer pulse.

[Also in Division G3] A machine for grinding or polishing irregular workpieces of wood, e.g. chairlegs, comprises a machine bed 1, Fig. 8, on which a sliding carriage 2 is horizontally guided which carriage carries a turntable 7 carrying a vertical pillar 8 on which a second carriage 11 is guided for vertical movement, on which second carriage 11 an axially movable, horizontal beam 20, 24 is rotatably mounted, which beam has a fixing apparatus for one or more workpieces at one end. The machine also includes grinding wheels 14-19 each driven by its own motor, having its spindle perpendicular to the direction of motion of the carriage 2 and being different from its or one of its neighbours in diameter and/or direction of rotation. In the machine described the beam comprises an axially movable arm 20 and a rotatable spindle 24. The spindle carries a fixing apparatus 27 which includes a pair of elements for engaging the ends of a workpieee under hydraulic pressure, and a motor 30 for rotating the elements and workpiece. The carriage 2, turntable 7, carriage 11, arm 20, spindle 24, and elements of the fixing apparatus 27 are moved by oil motors 3, 9, 12, 22, 25, and 30 respectively each controlled by a servo-valve operated by an electric or electromagnetic switch controlled from a magnetic or punched tape. A further switch and servo-valve controls the clamping action of the apparatus 27. The operation of the motors is so controlled by the tape that a workpiece fed from a magazine 58 is picked up by the apparatus 27 and moved over the grinding wheels 14-19, which may have convex, flat, or concave grinding faces, before it is discharged into a container 62. In this machine only the long faces of the workpieee are ground. In a second embodiment the carriage 11, Fig. 15, carries a second beam carrying a pair of hydraulically operated jaws 69, 70 which after grinding of the long faces of the workpiece grip the latter, which is then released from apparatus 27, and rotate it through 90 degrees to cause its ends to be ground on one of the wheels 14-19. The apparatus 27 may include means for gripping more than one workpiece, in which case similar portions of the workpieces are ground by different wheels simultaneously.

Abstract: 1,231,493. Photo-electric devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 June, 1968 [1 July, 1967], No. 30939/68. Heading H1K. A radiation-sensitive PN junction between a surface region and a wall isolated part of a layer epitaxially deposited on a substrate of opposite type is disposed above a more heavily doped zone of the same type as the layer buried in the surface of the substrate. A typical device (Fig. 2) is made by oxidizing the surface of a 3 ohm cm. P-type silicon wafer in wet oxygen conventionally forming a mask therefrom, prediffusing arsenic derived from an arsenic-doped silicon source through an aperture therein and continuing diffusion in oxygen to form an N+ zone 12, 10 Á deep. Boron is then diffused in similar manner through an aperture at the site of isolation wall 4, and after removal of the masking 0À3 ohm. cm. N-type silicon is epitaxially deposited to a depth of 10 Á. over the treated wafer face. After forming an oxide mask on the layer surface as above boron is diffused in to join up with that which has diffused outwards during epitaxial deposition to complete isolation wall 4.' P zone 5 and N+ contact zone 11 are then formed by successive masked diffusions of boron and phosphorus. Finally apertures for contacts are etched in the oxide and aluminium vapour deposited overall and shaped by photolithographic techniques to provide contacts 7, 8 with lateral extensions serving to facilitate attachment of leads or connection to other circuit elements in the wafer and to optically mask the edges of the PN junction. In a modification a further N region is diffused into zone 5 to provide an NPN structure, which with appropriately connected contacts may be used as a phototransistor or optoelectronic transistor, or as two photodiodes responding to different spectral regions connected in series or or parallel. A photothyristor is formed by providing another P region. In all cases one or more of the junctions may be a heterojunction between, for instance, A III  By compounds. The junction 15 should lie more than two minority carrier diffusion lengths beneath the layer substrate 14 to prevent leakage currents.

Abstract: 1,239,341. Controlling burners. ROBERTSHAW CONTROLS CO. 5 March, 1969 [6 March, 1968], No. 11793/69. Addition to 1,232,445. Heading F4T. [Also in Division G3] A control system for a burner comprises a casing 14 having an inlet 15 and outlet 16, a main valve 18 in a main flow passage having a diaphragm 19, a bleed flow passage 27 between the inlet and the outlet including an intermediate portion 35 communicating with an operating pressure chamber 21, an automatically operated bleed valve 32, and a thermostatic means 76 for operating the bleed valve 32 and is characterized by pressure-regulating means 38 having first and second settings for pressureregulation of the bleed flow and thermally responsive means 85 for moving the pressure regulation means 38 between its first and second settings. Cooling of the thermostat 76 causes a first circuit 78/81 to close actuating the bleed valve 32 and so reducing the pressure in the operating pressure chamber 21 that the main valve 18 opens. The main gas flow passes from the outlet 16 to the burner 10 and is ignited by the pilot burner 12. Should the thermostat 76 still cool, a second circuit 77/80 closes to pass a current over the thermal responsive means 85. The actuation of the pressure-regulating means may be made proportional control between its first and second settings (Fig. 4, not shown) by the inclusion of a bellows (193) filled with temperature-responsive fluid.

[Also in Division G1] Automatic apparatus for the transfer of a predetermined quantity of a liquid sample or of an upper liquid phase of a sample having a sedimented lower phase from one container 1 to another container 18 comprises a first tube 6 through which the liquid sample or phase is transferred, a second tube 7 connectible through 19 to a source of gas under pressure, tubes 6, and 7 being secured to a common support 5 which is movable rectilinearly to cause one end of each of tubes 6 and 7 to penetrate into container 1, the relative lengths of tubes 6 and 7 being such that the portion of tube 6 penetrating into the container is longer than that of tube 7, means 11, 12 for detecting the arrival of the liquid sample or phase at a predetermined location in tube 6, means 17 for effecting rectilinear movement of support 5 in response to signals from means 11, 12 and from element 13 for detecting contact between the end of tube 7 and the surface of the liquid sample or phase. Tubes 6, 7 may be of electrically conducting material when element 13 measures electrical conductivity. In operation, a start signal 21 to control unit 16 initiates downward movement of support 5 so that needles 6, 7 penetrate perforatable plugs 15, 14 in container 1. Movement of support 5 ceases when needle 7 touches the surface of the liquid. Air or gas pressure through tube 7 forces the sample into tube 6 until it reaches electrical conductivity or photoelectric gauge 11, when a signal causes support 5 to raise the tubes so that tube 6 emerges from the liquid, the sample meanwhile being forced by gas pressure into container 18. Another signal from 20 makes holder 5 lift the tubes out of container 1. If photocell 9 which is carried by support 5, is not actuated by lamp 22 throughout descent of the needles, i.e. if the needles reach the level of sediment 4 in container 1, a signal from element 10 makes support 5 raise the needles again and may operate a light signal for the operator. Containers 1 may form a continuous automatically moveable linear chain, or the containers may be chambers formed in film.

To free the king pin a lever 35 pivoted to the wedge at 34 is moved about a cam pivot 61 to withdraw the wedge, the lever arm continually changing during this movement until the lever occupies the position shown in dotted lines in Fig. 3, where a lip on the wedge engages a flange depending from the plate 12. As the king pin leaves the jaws it strikes a finger 75 of trigger 31 and rotates it causing the link 67 to pass under and raise the wedge to disconnct its lip from the flange and retain the wedge in a cocked position where the lip engages the link until a further coupling action takes place. The lever 35 is guided by a rod 46 and moves along a cam face 40 which causes up and down movement of the wedge to ensure engagement of its lip as required. A spring finger 45 retains the lever 35 when the wedge is engaged. The elastomeric block is formed of a hard and a soft block of material located in a housing 50.

In Fig. 1, the difference between the magnitude of a variable, measured at 4, and its desired value, set at 6, is determined by a comparator 5 the output of which is applied to an amplifier 12 having feedback through a capacitor 14 so that proportional and integral components of error are combined to control the number of pulses of constant duration applied during a given period by a generator 10 to correct the variable at 11. If the number of pulses is a maximum, such as might occur during start-up or upon a sudden change of the desired value, the time constants of a transistor circuit 22 are overcome and a delayed relay 21 is energized to short out condenser 14 and prevent excessive integration signal build-up. Alternatively, relay 21 may be operated in dependence on the output of amplifier 12. Addition of a differential component of control is referred to. In a modification, Fig.4 (not shown), the integral component is derived by feedback from the output of a pulse generator controlling the variable.
