Title: A laser
Inventor: ROBERT LAMB
IPC: H01S3/083
Filed: 2018-03-09
Abstract: A laser system comprising an optical ring resonator where one or more elements is provided to correct a beam shape. The element such as a phase distortion rectifier, may correct wave-front aberration of a beam in the resonator, and may comprise a modifying element with a profiled surface or have a varying refractive index, and may be reflective or transmissive. The element preferably modifies the spatial distribution of phase across the aperture of the beam. Preferably the ring resonator comprise mirrors 3 and gain medium 2 which outputs two counter rotating beams (ic, ia). The ring preferably includes a polarising beam splitter 4 arranged with a reflector 5 (such as a corner retroreflector) so that both beams can be coupled at an output (ic+ia). The element may correct the phase distribution of one beam to better match the other beam. A modifying element may be positioned at 6, where beam ic passed through the element twice. A beam rectifier element maybe positioned at output 7A or be positioned within the ring at 7’. An alternative not shown in the figure is to have a profiled surface for one of the mirrors forming the ring.

Title: Artificial candle with moveable projection screen position
Inventor: Carlos Carpintero
IPC: F21S10/04
Filed: 2018-09-07
Abstract: A flameless candle includes a candle body 110 forming an interior region containing a light source 150. A force-inducing portion 122 such as an electromagnet or electric motor is configured to alternatively induce a first mechanical force and a second mechanical force. A flame-shaped projection screen 120 receives the first mechanical force and responsively moves to a first folded position and receives the second mechanical force and responsively moves to a second upright position. When the projection screen is moved to the second position, the light source is automatically energized so that light is emitted onto the projection screen. When the projection screen is moved to the first position, the light source is automatically de-energized such that light is not emitted. A lens and pendulum arm (132, 134, Fig. 4) may be swung by an electromagnet to sweep light from the light source 150 onto the projection screen 120. The light source 150 may itself be controlled to achieve a flickering flame effect.

Title: Valve with pressure seal protection
Inventor: RICHARD ELLIS
IPC: B65G53/66
Filed: 2019-03-01
Abstract: A valve 100, and associated method of flowing particulate material and a carrier gas, comprises a body 107 with a fluid passage between an inlet 103 and outlet 107. A rotatable closure member 135, within the passage, has a convex sealing surface 138. Closure member 135 is rotatable between closed and open positions so as to prevent/allow flow through the passage. A sealing ring 147 extends around the passage and is moveable so in a first position it forms a seal around the circumference of the convex sealing surface 138, or in a second position allow a gap / annular clearance 166 therebetween. When closure member 135 is in a closed position the annular clearance166 between the fluid passage surface and the sealing surface tapers 164 towards the sealing ring, so as to become narrower gap 166. When there is a pressure drop across valve 100 and before closure member 135 is moved to fully open the valve, material flowing through the valve experiences a dynamic pressure rise towards the circumferential gap, decreasing flow velocity and wear. A pressure vessel and a particulate material conveying apparatus utilising the valve 100 are also disclosed.
