  • Patent number: 6897749
    Abstract: A superconducting magnetic energy storage (SMES) device including a first coil made of superconducting material, a cooling mechanism for cooling the first coil to superconducting temperatures, a second coil inductively coupled to the first coil for inputting emergy to, and/or outputting energy from, the first coil, and a switch for switching the first coil between a superconducting condition and a non-superconducting condition. The first coil is arranged as a closed loop electric circuit having no connecting device mechanically connected to it for inputting or outputting energy. The switch includes a third coil for the application or removal of a magnetic field for switching the first coil between its non-superconducting and superconducting conditions. A method inputs energy to and/or outputs energy from the first coil and a power supply system utilizes the device and method.

  • Publication number: 20040114403
    Abstract: A superconducting magnetic energy storage (SMES) device (1) comprising a first coil (2) made of superconducting material, cooling means (3) for cooling the first coil to superconducting temperatures, a second coil (4) inductively coupled to the first coil (2) for inputting energy to, and/or outputting energy from, the first coil (2), and switching means (5) for switching the first coil (2) between a superconducting condition and a non-superconducting condition. The first coil (2) is arranged as a closed loop electric circuit having no connecting means mechanically connected to it for inputting or outputting energy. The switching means (5) comprises a third coil for the application or removal of a magnetic field for switching the first coil (2) between its non-superconducting and superconducting conditions. The invention also relates to a method of inputting energy to and/or outputting energy from the first coil (2) and to a power supply system.

  • Patent number: 4023754
    Abstract: Driverless vehicles, confined to motion in one direction along a defined path divided into blocks, receive commands from a central unit in the form of encoded command signals radiated from an elongated radiator. Each vehicle progresses only while receiving signals regularly. The radiator comprises two parallel stretches, each extending all along the path but divided into sections, each section being as long as a block but extending across a block boundary, with a section of each stretch paired with a laterally adjacent section of the other stretch. In each section pair, the segment of one section that lies in one block is shielded, the remainder unshielded; the other section of the pair has opposite shielded and unshielded segments.

  • Patent number: 3949728
    Abstract: A clay pigeon trap comprises a shaft member, provided with an adjustable support mounting, which carries at one end a casing containing a bearing providing a pivot mounting for an angularly movable throwing arm and tensioning apparatus for spring loading the throwing arm prior to a throwing stroke. The throwing arm has a pivot shaft projecting perpendicularly from its underside to engage in said bearing and the tensioning apparatus includes a freely rotatable tensioning bush within the casing, a helical coil torsion spring coupling the tensioning bush to the pivot shaft within the casing, and a tensioning arm which is detachably secured to the tensioning bush and which projects outside the casing to enable the bush to be turned so as to tension the spring by manipulating the tensioning arm whilst the throwing arm is held alongside the shaft member in its rearwardly directed position.
