Title: Electrical Current Limiting Devices
IPC: B23H3/02
Filed: 1969-02-21
Abstract: 1,194,815. Protective systems. SIEMENS A.G. 21 Feb., 1969 [24 Feb., 1968], No. 9601/69. Heading H2H. [Also in Division C7] In order to protect electrical apparatus from the effects of an excessive current flow therethrough means are provided to detect a sudden change of voltage across the load and which means are then effective to limit the current through the load. An electrolytic forming machine comprising an anode 3 and a cathode 4 is supplied with direct current derived from an A.C. source RST by way of a voltage regulator 14, 15, a transformer 10 and a full wave rectifier 6. The voltage across the electrode gap 2 is sensed by a circuit comprising a capacitor 20 and the primary winding 22 of astep-up transformer 21. A sudden change in the voltage across the electrode gap 2, due to impurities in the electrolyte or to air bubbles therein, causes a voltage to be developed across the secondary winding 23 of transformer 21 which voltage is rectified by diode 26 and applied to a control device 17. The device 17 is operative to cause a further device 7, such as a thyristor to become conductive so as to short circuit the gap 2 thereby to divert current from the electrode gap 2. At the same time the control device 7 is effective to cause the voltage regulator 14, 15 to reduce the voltage applied to the electrodes 3, 4. The transformer 21 may be replaced by a magnetically controlled semi-conductor device such as a HALL device.

Filed: 1939-03-28
Abstract: 526,904. Aircraft landing gear. TAMPIER, R. March 28, 1939, No. 9678. Convention date, April 8, 1938. [Class 4] A retractable three-wheeled undercarriage for aircraft comprising a front medial wheel and two side wheels is operated from two transverse shafts connected to a common drive, one shaft causing the front wheel to be moved in the longitudinal plane of the machine and the other shaft actuating the side wheels which are moved in a plane transverse to the machine. In the form shown, which is suitable for use with the arrangement of inclinable propellers described in Specification 526,899, the invention is applied to a three-engined aeroplane having a front landing-wheel 5 disposed centrally of the fuselage and side landing wheels 6 and 7 disposed respectively at the rear of the engine nacelles 1 and 2. A transverse shaft 11 carries at its ends frames 12, 13, each supporting an engine and a gear quadrant 32<1>, 33<1>, with which mesh level gear wheels 32, 33. Rotation of the shaft 11 thus causes shafts 30, 31, which are carried in bearings infixed frames 18, 19, to rotate about longitudinal axes and extend or retract the wheels 6 and 7 which are on offset portions of the shafts 30, 31. The shafts 30, 31, pass through clearance slots in bosses 26, 27 on the shaft 11. The front landing wheel 5 is carried on a transverse shaft 10 to which is fixed a toothed sector 48. The shafts 10 and 11 are driven from a motor 43 through the gearing shown. The invention may be carried out without any driving connection between the shaft 11 and the engine frames, in which case the gear quadrants 32<1> and 33<1> may be directly fixed to the shaft 11.

Title: An improved vessel for handling corrosive liquids
IPC: B65D85/84
Filed: 1945-04-18
Abstract: 590,762. Vessels for corrosive liquids. ARNOLD, J. C. (Standard Oil Development Co.) April 18, 1945, No. 9713. [Class 66] A lined vessel comprises, e.g., an upper cylindrical part 14 and a lower frusto-conical part 15, which, respectively, have metallic outer shells 11 and 19 secured together at 20 and have, in common, a corrosion resistant, unbroken metallic lining 16 made preferably of lead and fitted flush with them. The shells have slots 12 at regular or staggered intervals. The cylindrical part of the lining is supported by passing a projection 18 (integral with the lining and preferably reinforced by a block of lead 17 fused to both), through each slot and bringing the projection to bear against the outside of the shell, e.g., by turning the projection over a shelf 13 secured to the shell 11, coplanar with the base of the slot. The frusto-conical part of the lining is secured by cutting slots therein which coincide with the shell slots and then burning the lining to sheets of lead 24, bearing outside the shell, by fusing lead into the slots so as to form corelike projections 25. Vessels having curved or flat surfaces may be so lined. An additional acid resistant ceramic lining 21, may be superimposed on the frusto-conical metal lining.

Filed: 1938-03-30
Abstract: 513,317. Lighting fittings. GENERAL ELECTRIC CQ., Ltd., and BEGGS, S. S. March 30, 1938, No. 9722. [Class 75 (ii)] In a directional lighting fitting, adapted to cooperate with a small source of light, at least one face of the fitting viewed from a preferred direction comprises a number of elements, each of which directs light into the preferred direction whereby the effective brightness of the face as seen by a normally placed observer in the preferred direction is not substantially greater than it would be if light of the same intensity in that direction came from a source uniformly distributed over the face, and at least some of the elements each directs light also into neighbouring directions, while only a few of the elements direct light into those directions in which the intensity is much less than in the preferred direction. The elements may be constituted by prisms with curved faces or by prisms with straight faces combined with flutes having their edges parallel to the edges of the prisms to form a combination optically equivalent to a prism with a curved face. Fig. 1 shows a glass drumlike fitting having on its outer surface annular prisms with curved faces 3 and horizontal edges 4 and on its inner surface prisms with straight edges 9 and'curved faces 10. Fig. 3 shows a glass panel with concentric prisms on one face and straight prisms on the other. Fig. 6 shows a part of a glass panel in which the elements 20 have a curvature in the planes perpendicular to OX and OY. Specifications 19185/93, [Class 75], and 408,419 are referred to. Reference has been directed by the Comptroller to Specifications 217,539, 240,569, 242,686, 312,750, 337,398. [all in Class 75 (ii)], 393,972 and 398,419.

Title: Automatic noise limiter
IPC: H04B1/10
Filed: 1977-03-08
Abstract: 1525904 Noise limiter MOTOROLA Inc 8 March 1977 [25 March 1976] 09766/77 Heading H4L In a circuit for limiting the amplitude of interfering pulses 24 in an AM receiver, the AM signal 22 is detected in 30 and filtered to produce an audio signal 40 having a D.C. component whose amplitude is proportional to the peak level of the AM signal 22. The D.C. component is extracted by low-pass filter 50 comprising 52, 54, 56 and the audio A.C. by high pass filter 62, 64. Diode 70 has a temperature compensation network 90 and bias network 74 arranged such that equal currents flow in 70 and 91. Diode 70 is biased such that it is conducting whenever the instantaneous value of the audio signal is lower than the D.C. signal, enabling the audio signal to pass through 70 to the output amplifier 92. Thus any interfering pulses 24 of greater amplitude than the peak value of the audio signal cause 70 to become reversed biased and are thereby limited in amplitude to this peak value. The bias means also ensures that 70 has zero bias when no input signal is present.

Abstract: 687,111. Regulating reciprocating pumps. BASTIAN & ALLEN, Ltd., and COX, W. J. G. April 20, 1951 [April 24, 1950], No. 9988/50. Class 102 (i) [Also in Group XXXV] A pumping apparatus includes a reciprocating pump having its inlet or delivery valve of the kind which is automatically opened for the appropriate periods by the action of the fluid therein, a magnet associated with the valve and arranged to cooperate with a part of magnetic material to hold the valve off its seat, and control apparatus whereby the magnetic force acting on the valve can be varied progressively between a force sufficient to hold the valve continuously in its open position, when it is next opened by the action of the fluid thereon and thus render the pump inoperative, and a force insufficient materially to affect the normal closing of the valve. Fig. 1 shows an arrangement in which an electrode boiler A is supplied from a source of electrical power E or is fed with water by a pump F driven by an electric motor F<SP>3</SP>. The inlet valve F<SP>2</SP> is controlled by an electromagnet J having coil J' supplied by a transformer K in the supply line D so that the output of the pump is varied according to the current consumption of the boiler; a rheostat K<SP>1</SP> varies the current in the coil J<SP>1</SP> relatively to the current in the supply line. Fig. 2 shows an arrangement in which the coil M' is mounted on a core M which is adjustable by lever N to vary the magnetic effect on the valve L and in such an arrangement, the rheostat K<SP>1</SP> would be unnecessary. In alternative arrangements, the core is partly surrounded by an adjustable flux-diverting member. Fig. 4 shows an arrangement in which the valve stem L' is formed as a permanent magnet and a soft iron control member P is adjustable on a guide P<SP>1</SP>. A relief valve H<SP>4</SP> actuated by the pressure of the teed water supply may be fitted.

Title: Synchronizing circuit
Inventor: SATO MASUJIRO
IPC: H04L27/14
Filed: 1986-01-07
Abstract: PURPOSE:To prevent malfunction of a synchronizing circuit by synchronizing an internal synchronizing signal with an external device after a reception electric field reaches a prescribed value or over. CONSTITUTION:Since a trigger input terminal of one-shot multivibrator 5 is connected to an output terminal of an oscillation limit device 2, the one-shot multivibrator 5 sends an output pulse only when an electric field is a threshold value or over at a change point of a data signal. An oscillator 7 outputs a signal having a frequency being nearly N-time (N>=1; integral number) of the data rate and is connected to a clock input of a frequency divider 6. Since the frequency divider 6 is reset by an output pulse of the one-shot multivibrator 5, when the data signal is correct, the output of a frequency divider 61/N rises at the center of the data signal and it is outputted as a synchonizing signal.

Title: Feeding method for recording chart
Inventor: TERANISHI HIROYA
IPC: B65H3/06
Filed: 1989-01-09
Abstract: PURPOSE:To restrain the head write-in position of a recording chart from scattering so as to be stabilized by detecting an amount of slippage when the recording chart is separated so as to be carried, and thereby changing the number of driving pulses for a recording chart carrying drive motor depending on change in an amount of slippage. CONSTITUTION:The first paper sensor 22A and the second paper sensor 22B are disposed between a separating roller 11 and a platen roller 14, which are adapted at specified intervals to detect the tip end of a recording chart 10. An amount of slippage is detected between the first and second paper sensor 22A and 22B so that a correction factor is computed by the CPU 24. A pulse motor 23 is actuated based on the number of corrected driving pulses to carry the recording chart from the position of the second paper sensor 22B to the position of a nip so that the head write-in position of the recording chart is fixed. The head write-in position can thereby be retained stably at all times regardless of change in an amount of slippage.
