Title: Power supply current regulation
IPC: H02M7/155
Filed: 1963-04-08
Abstract: 1,008,256. Automatic control of current and voltage. VARIAN ASSOCIATES. April 8, 1963 [April 13, 1962], No. 13948/63. Heading G3R. In a regulating arrangement for a supply to the windings an electromagnet 6 from an alternating-current input through a transformer 1 and rectifiers 2, 3 the value of the current through the windings is maintained constant by controlling the base bias of a transistor 8, or paralleled transistors,by a regulator circuit responsive to the difference between the output of a reference source 10 and the voltage across a resistor 7 in series with the windings. The voltage across the transistor 8 is compared in a transistorised voltage regulator 11 supplied through a bridge rectifier 18 from a transformer fed at A from the transformer 1. The voltage regulator 11 develops pulses, delayed by an amount proportional to the voltage across the transistors 8, which are fed through a transformer 16 to control the firing point of controlled rectifiers 14, 15 so as to tend to maintain constant the voltage across the transistor 8. A potentiometer 34 is connected in parallel with the series combination of the windings if the electromagnet 6 and the resistor 7 and a tapped voltage, through an over-voltage control 17 influences the regulator 11 to prevent damage to the transistor 8 by large voltages being set up across the resistor 34.

Title: Improvements in or relating to direction finding apparatus
IPC: G01S1/02
Filed: 1921-05-20
Abstract: 185,169. Jackson, W. J. Mellersh-, (Taylor, A.). May 20, 1921. Bearings, determining; directive signalling; aerials.-A rotatable loop-aerial is mounted over a ship's compass and carries an indicator which coacts with a card fixed to the compass dial and previously calibrated for quadrantal error, so that the correct bearing of a distant wireless transmitting- station can readily be ascertained. The shaft 6 of the loopaerial A is mounted on ball bearings 8 over the binnacle 2, as shown in Fig. 1, and is adjusted for maximum or minimum sound in the telephones by means of a hand-wheel 21. The leads to the detecting-circuit are taken from slip-rings 12, 13. The end of the shaft is supported in a bracket 16 fixed to the binnacle, and is provided with bifurcated arms 19, Fig. 3. carrying stretched indicating-wires 20 which sweep around the quadrantal-error card 22. This card is initially calibrated by swinging the ship about a known source of wireless signals. Fig. 5 shows the receiving circuits. The loop aerial may be connected to a further aerial or to a capacity B by means of a switch q, and condensers C, C1, C2 are provided for separately tuning the closed circuit, comprising the loop-aerial, in a symmetrical manner about the earth connection E. To do this, the switch c is placed in contact with the point d so as to short-circuit the branch C2, L and the switch g is thrown over to the upper position. The amplifier e and detector f are then across the closed circuit, and the loop is oriented for maximum or minimum sound. Similarly the open antenna circuit may be tuned by opening the switch c, throwing the switch g into the lower position, and suitably adjusting the condenser C3 and inductance L. If the switch c is brought into contact with the point a, the symmetry of the closed circuit is disturbed by the introduction of the capacity C4, and then, whether the switch g is in the upper or lower position, the telephones T receive energy from both the open and the closed circuits.

Title: Improvements relating to liquid resistance controllers
Inventor: RAMSDEN LLOYD DOUGLAS
IPC: H01C10/02
Filed: 1954-05-14
Abstract: 773,201. Variable liquid reactors. ENGLISH ELECTRIC CO., Ltd. May 13, 1955 [May 14, 1954], No. 14179/54. Class 37. In a variable liquid resistor of the kind in which fixed and moving electrodes are mounted axially in an electrolyte so that movement of the electrodes result in a variation of resistance, the fixed electrodes are generally conical or frusto-conical in external form and the moving electrodes are annular in form with their internal surfaces tapered in the same direction as the taper on the fixed electrode. An annular column of electrolyte is defined by an insulating baffle and the cross-sectional area and length of the column is such that a large amount of the total resistance is cut out of circuit with a comparatively small amount of movement of the moving electrode from the maximum resistance position. The Figure shows a variable liquid resistor in which a fixed insulating tube 10 is mounted via a base plate 11 on the floor of a tank of electrolyte 12. The fixed electrodes 13 are steel nickel plated, nickel clad on the outer conical surface, and baffles 21 are provided to increase the resistance passed between the electrode 13 and the floor of the tank. Each moving electrode 22 is in the form of an annular ring tapered to conform with that of the outer surface of fixed electrode 13 and the surface is also nickel clad. An inner insulating tube 28 closed at the upper end with holes 31 allowing for circula. tion of the electrolyte provides an annular column of electrolyte between tubes 10 and 28. The length and area of this column is such that as the movable electrode 22 is lowered from the maximum resistance position shown in the drawing a large change of resistance takes place initially and a smaller change as the movable electrode 22 moves in proximity to the fixed electrode 13. As illustrated, approximately 75 per cent of the total resistance is cut out of circuit during the first 25 per cent of the total travel of the moving electrodes. The characteristic of this non-linear change of resistance may be varied by altering the position of the baffle 28 by means of the nut and screw 30, 29. Three such variable resistors may be mounted together, Fig. 1 (not shown), to provide variable resistance in each phase of A.C. used for operating A.C. mine winders.

Title: Improvements in and relating to cam mechanism for operating reciprocative parts
IPC: B25B7/20
Filed: 1927-05-28
Abstract: 271,902. Perrin, F. May 31, 1926, [Convention date]. Punching; stamping; riveting. - A cam mechanism for operating reciprocating parts of punching, riveting, stamping, &c. machines, hand or mechanically operated, comprises a hand lever or other operating device of a cam disc with a number of cam projections, a ratchet wheel moving therewith and having principal teeth equal in number to the cam projections or a multiple thereof, finer teeth on or co-operating with the principal teeth, pawl mechanism on the operating device for engaging the principal teeth and retaining pawls engaging the secondary teeth to hold the cam disc and ratchet wheel against backward movement. One construction of device for fixing seals on bag cords comprises a body carrying a lever arm a and formed with a cushion a' and guide a<2> for a plunger b operated by a cam e on a spindle c, on which the movable lever arm d is mounted. The cam e has four operating projections, each adapted to move the plunger through its working stroke, a spring n returning the plunger to its initial position. Rotating with the cam e is a ratchet wheel f having a number of main ratchet teeth equal to or a multiple, of the number of projections of the cam e, eight in the construction shown. Each main ratchet tooth has a number of secondary ratchet teeth; a spring pressed pawl g on the movable lever arm d is adapted to engage the main teeth only, whilst a retaining pawl on the fixed body of the pliers engages both main and secondary teeth. The movable lever arm d has a range of movement through 45‹ and is held in raised position by a spring m. With this construction two complete closing movements of the lever arms are necessary to rotate the cam e through the space of one projection so as to depress the working plunger b through its complete stroke and permit its return under the influence of the spring n to its initial position. If for any reason the closing movements of the lever arms are not completed the next movement will only result in the completion of the working stroke of the plunger, thus ensuring the complete closing of the seal; also, the return of the plunger to its initial position and the removal of the tool from the seal cannot take place until the stroke of the plunger has been completed. The ratchet wheel f is preferably constructed in two parts, one on either side of the cam e, as shown in Fig. 2. Fig. 5 shows a modification adapted for closing the outer and inner rims 2, 3 of the lead seal 1 shown in Fig. 7, the plunger being formed in two coaxial parts, an inner part b and an outer ring part B, actuated respectively by links q, Q, levers o, 0, cams e, E and ratchet f, the plunger portions being returned to the initial position by springs n, N engaging tail pieces on the levers o, O. The front of the tool has a beak r adapted, to engage the cord of the bag.

Filed: 1964-04-08
Abstract: 1,067,021. Electron microscopes. HITACHI Ltd. April 8, 1964 [May 24, 1963], No. 14509/64. Heading H1D. A specimen tilting device for an electron microscope includes means for producing an alternating deflection of the electron beam in a direction parallel, or perpendicular, to the axis about which the specimen tilts, thereby facilitating adjustment of the specimen to ensure that it may be tilted about an axis which corresponds to a given line in the image of the specimen formed on a viewing screen, by observation of the direction of oscillation of the image on the screen, and rotation of the specimen about an axis perpendicular to the tilting axis until the direction of oscillation of the image is either parallel or perpendicular, respectively, to the given line in the image. For producing the deflection of the irradiating beam when adjusting the specimen, the specimen holder includes either a pair of coils (6, Fig. 2, not shown), mounted to provide a magnetic field perpendicular to the axis (3) about which the holder can tilt, or parallel to that axis, as in Fig. 2 (not shown). Alternatively, a ring-shaped electrode (8, Fig. 3, not shown), may be mounted on that portion (2) of the holder which tilts with the specimen, to produce a deflection of the irradiating beam in a direction perpendicular to the tilting axis (3) when the holder is tilted out of alignment with the optical axis of the microscope. The latter arrangement may be calibrated to permit the deduction of the angle of tilt about the tilting axis from the amplitude of the image oscillation. Reference is also made to the use of a coil rather than an electrode in the arrangement of Fig. 3 (not shown).

Title: Process for the electrical separation of suspended particles from gaseous fluids
IPC: B03C3/82
Filed: 1932-05-23
Abstract: <PICT:0402423/III/1> In a process for the electrical separation of suspended particles from gases by means of a non-homogeneous non-discharging field, the gases are treated under superatmospheric pressure.  It is stated that the use of increased gas pressure enables a greater potential difference to be applied to the electrodes without the formation of a discharge, thus increasing the electrical forces acting on the particles.  According to the arrangement shown, the gases are passed through a chamber 1, the walls of which are sufficiently thick to withstand the operating pressure, and between the tubular collecting electrode 2 and the high-tension electrode 3 which may be a rod of such a cross-section, size and shape that no discharge occurs.  The insulators 5 and 7 are isolated from the gas stream by the intermediate walls 14 and 15. The pressure employed is preferably above 2 atmospheres and may be as high as 150 atmospheres.
