Title: Non contact sensor having means to convert linear motion into rotary motion
Inventor: ERICKSON STAFFAN
IPC: G01D5/20
Filed: 2009-12-17
Abstract: A non-contact sensor system is provided that comprises a first sensor element disposed within a first member having an axis Y, and a second member configured to rotate about the axis Y at a value X. The second member is configured to interface with the first member. The non-contact sensor system further comprises a second sensor element disposed on the second member proximate the first sensor element without physically contacting the first sensor element, and the first sensor element and the second sensor element are operatively coupled to facilitate sensing the value X. The non-contact sensor system may be configured to sense velocity, acceleration, and other values. In the embodiment, the linear motion of a helical member causes the rotation of a member through which it passes. A sensor part on the rotating member is detected by another sensor part not in contact with it. The sensing of movement may be based on the convention detection of the movement of a magnetic member or a change in capacitance for example.

Title: Improvements in and relating to electric protective system having grounded phase selectors
IPC: H02H3/353
Filed: 1949-04-13
Abstract: 663,055. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd. April 13, 1949. [April 29, 1948] No. 10039/49. Class 38 (v). A protective system for a polyphase circuit having single-pole circuit-breakers, utilizes wattmetric relays to cause the tripping of only the faulty phase or phases on the occurrence of an earth fault. Each relay S1-2, S2-3, S3-1, has a coil energized by a selected line-to-line voltage by means of a potential transformer 6, and a coil energized by an electrical quantity which may be the residual voltage from the "open-delta" secondary winding of a transformer 7, or alternatively the current in a neutral-to-earth connection, Fig. 10 (not shown). The relays are constructed so that they produce maximum operating torque when the electrical quantity leads the line-to-line voltage by an angle corresponding to substantially 105 degrees for residual voltage. For example, in the event of an earth fault on phase 1, the voltage between phases 2 and 3 which is applied to one coil of the relay S2-3 would have the correct phase relationship to the residual voltage applied to the other coil of the relay to cause the relay to close its contacts to energize the trip coil 4 of the circuit-breaker 5 to open the faulty phase 1. An earth faul directional relay G supervises this action as the relays S are not directional. In the event of a double phase-to-earth fault very close to the protective equipment causing a complete collapse of the voltage triangle, only one relay S would operate, so that to ensure the tripping of both the faulty phases, directional distance relays x ... z are provided ; each of these relays having two current coils each responsive to the current in a phase conductor and a voltage coil responsive to the voltage between these phase conductors. The Specification describes with the aid of vector diagrams the manner in which the system functions under various fault conditions.

Title: Improvements in or relating to circuit arrangements for starting self-generating controlled semi-conductor rectifier oscillators
IPC: H02M7/516
Filed: 1964-03-10
Abstract: 1,036,251. Controlled semi-conductor rectifier oscillating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 10, 1964 [March 13, 1963], No. 10051/64. Addition to 958,311. Heading H3T. The invention relates to a circuit arrangement for starting a self-generating controlled semiconductor rectifier oscillator of the type disclosed in the parent Specification, i.e. comprising a capacitor connected to a direct-voltage source through a resistor, a discharge element which is in series with a direct current impedance being connected across the capacitor, so that a given value of the voltage across the capacitor the discharge element becomes conductive and a pulse is produced across said impedance, which pulse is fed to the control electrode of a controlled rectifier of the oscillator. According to the present invention the time-constant of the network comprising the capacitor and resistor, based upon the voltage of the direct voltage source and breakdown and extinguishing voltages of the discharge element, is so chosen that the recurrence period of the generated starting pulses is so long that the switching-on phenomena produced in the oscillator by a first starting pulse are substantially ended at the instant the next starting pulse appears, thereby preventing dangerous voltage surges on the semiconductor rectifiers.

Abstract: 833,902. Ammunition fuzes. BREVETS AERO-MECANIQUES S.A. April 1, 1958 [April 25, 1957], No. 10463/58. Class 9(1) A direct action percussion fuze for spinstabilized projectiles comprises a casing 2 in which a slidably mounted striker 1 for firing a primer 3 is immobilized by a split sleeve 4 surrounding the striker and abutting a shoulder 1a thereof, the sleeve being held against expansion during the initial part of the trajectory, to delay arming, by a strip 5 wound around the sleeve in such a way that as the strip unwinds, due to centrifugal force produced by the spin of the projectile, the sleeve 4 tends to rotate around the striker in the sense opposed to the centrifugal force. The strip 5 may be resilient or non-resilient metal, e.g. tin, and have say twelve turns, the inner end being anchored to the sleeve 4 and the outer end secured to the casing 2 either permanently or by centrifugal force developed when the projectile is launched. An outer split ring 6 may retain the strip 5 in position, the ring 6 opening under centrifugal force as soon as the projectile starts to spin. The sleeve 4 split at 4a is provided with radial notches 4b, 4c to increase its flexibility and to prevent the sleeve opening until the strip is fully unwound the inner end of the strip may be pressed into the notch 4b on each side of the split 4a. When the ring 6 has moved into contact with the outer surface of the annular housing 7, the strip 5 is released and also moves outwardly causing the sleeve 4 to rotate on the striker 1 in the reverse direction to the spin of the projectile. When the strip is fully unwound, the bent portions leave the notches 4b and the sleeve 4 expands under centrifugal force and frees the striker for operation on impact.
