  • Patent number: 11131863
    Abstract: A method of forming an optical device in a body (32), comprises performing a plurality of laser scans (34,36) to form the optical device, each scan comprising relative movement of a laser beam and the body thereby to scan the laser beam along a respective path (34a, 34b 34f; 36a, 36b 36f) through the body to alter the refractive index of material of that path, wherein the paths are arranged to provide in combination a route for propagation of light through the optical device in operation that is larger in a direction substantially perpendicular to the route for propagation of light than any one of the paths individually.

  • Patent number: 9869466
    Abstract: A heat recovery system arranged to heat water includes at least one heat exchanger (9) arranged to heat water by heat exchange with waste heat. A storage reservoir (11) is arranged to store water heated by the heat exchanger (9). The heat exchanger (9) is switchable between a first mode of operation in which water is circulated by a pump (12) in a circuit that includes the storage reservoir (11) and the heat exchanger (9), and a second mode of operation in which water is circulated by the pump (12) in a circuit that by-passes the heat exchanger (9). Heated water of at least a desired minimum temperature can be supplied to at least one outlet during both the first and second modes of operation.

  • Patent number: 9266683
    Abstract: A two mass, single motor bi-directional conveyor for conveying solid objects, granular and powder material. The unit utilizes the two mass sub-resonant natural frequency system driven by a single motor with counterweight wheels. The forces created by the rotation of the counterweight wheels results in a trough stroke at an angle from the horizontal pan resulting in material motion. The trough stroke is absorbed with isolation springs mounted between the conveyor and the ground.

  • Publication number: 20080292906
    Abstract: Magnetic medium recording performance can be enhanced by irradiating a magnetic medium with ions having an acceleration voltage of between 10 keV and 100 keV to induce exchange coupling between grains of the magnetic medium. The magnetic medium is exposed to a cumulative ion dosage of between 1013 ions/cm2 and 1017 ions/cm2 using a non-patterned exposure of the magnetic medium. The ions can be selected from the group consisting of H+, He+, Ne+, Ar+, Kr+, and Xe+. Alternatively, the ions can be selected from the group consisting of Ga+, Hg+, and In+.

  • Publication number: 20050258017
    Abstract: A balanced flat stroke bi-directional conveyor for conveying object, granular and powder material. The unit utilizes the skewed sine wave trough stroke principle using primary eccentric counterweights wheels driven by a motor running at the secondary speed and equipped with the secondary eccentric counterweight wheels and a third counterweight wheel. The forces not in line with the trough stroke are absorbed with an isolation spring mounted between the drive assembly and the base, while the forces in line with the trough are balanced via a connected balancer.

  • Patent number: 6456815
    Abstract: The present invention relates to improved methods of coating donor members with waterbome coatings, wherein a resin, a pigment, and water are combined in proportions effective to provide a donor member precursor composition; the donor member precursor composition is subjected to high pressure communition to provide a donor member conductive coating composition; and the donor member coating composition is coated onto a substrate. The present method advantageously provides a donor member coating which is substantially free of air pockets or defects. In preferred embodiments the resin is a phenolic resin, preferably a waterborne phenolic resin, such as a phenol-formaldehyde resole, and in other preferred embodiments the pigment is selected from the group consisting of carbon black, graphite, magnetite, nigrosine, and combinations thereof.
