Abstract: A method, an apparatus, and a computer program product for electromagnetically designing a shaped-reflector multibeam antenna (100) are disclosed. An initial configuration of the multibeam antenna (100) for given beam directions is provided of reflectors (110,120) shaped with an initial reflector shaping process (612) and feeds of an initial specification (614).

Abstract: A compact, broadband laser source is realized by using a rare earth dopant to define a laser gain spectrum and by using holographic imprinting techniques to form a wavelength selection element for selecting a particular wavelength from within the gain spectrum. Artificial broadening of the gain spectrum can be achieved by establishing varied (e.g., randomized) domains of space charge within a rare earth-doped laser gain medium. Compactness can be enhanced by fabricating the laser gain medium and wavelength selection elements within a single member, such as a photorefractive crystal substrate. Flexibility in the selection of a wavelength can be obtained by holographically imprinting multiple sets of wavelength selection elements.

Abstract: A method and a pig feeder is described for mixing metered amounts of liquid and dry feed. Both are caused to migrate in a downward direction over a mixing region to a feeding region of a feeding trough. The liquid and dry feed are both dispensed from above the mixing region so as to fall onto the mixing region in a generally downward manner, and are delivered onto the mixing region in a predetermined dispersal pattern. The liquid is delivered on to the mixing region in a similar pattern, typically by means of a spray nozzle. The delivery of feed and water is animal activated, and the animal activation is inhibited at intervals so that the feeding cycle of the animals is controlled. To this end the intervals between inhibition and/or the duration of each inhibition is adjustable. The level of feed in the trough is sensed to prevent build up of uneated mixed feed in the trough.

Abstract: A mobile saw bench is designed for cutting elongate workpieces such as elongate open or closed steel sections. The mobile saw bench comprises a base structure which is mounted on four castor wheels. Formed continuous with the base structure is an intervening frame structure to which a benchtop is mounted.

The universal coupling is mounted to an underside of the benchtop and is releasable clamped to an elongate member which is in the form of a rigid measuring staff. The universal coupling allows pivotal movement of the benchtop relative to the measuring staff which is stationary.

Abstract: A recirculation system for circulating distillate during gas fuel operation so as to reduce or eliminate distillate carbon formation. The recirculation system keeps the distillate's temperature below the carbon formation limit by circulating the distillate back to a heat sink and/or heat exchanger. The recirculating flow also exercises the flow dividers' gears without having to perform fuel transfers. Further, the system evacuates air from the liquid fuel lines to further decrease the likelihood of carbonaceous residue forming on any interior surfaces that are actually exposed to distillate.

Abstract: A paintball container comprises a body 12 and a lid 14. The lid 14 is hinged to the body 12 at one side, and has a tab 42 at the other side to facilitate opening of the container. The body 12 has a guard 26 formed on it adjacent to the tab 42 on the lid. The guard is substantially U-shaped and bounds a recess 30 into which a user can insert their thumb to pull up the tab 42 to release the lid. The guard 26 prevents accidental opening of the lid, for example when the container is being removed from a harness in which it is being carried.
