Abstract: A system and method is provided for enabling an online user to place bets concerning incidents occurring during a game or sports event. This is done by providing a portal for a user to place a bet predicated on a defined incident occurring during a predetermined time segment of the event. The platform includes a module for calculating odds and prize returns for said incident to occur during said sports event or game in response to a user request, a GUI presentation and a settlement engine.

Abstract: Apparatus for collecting solids settling at the bottom of a liquid reservoir, the apparatus including: a plurality of suction head assemblies, each suction head assembly including a hollow suction head configured to cause agitation of solids settling in or around the suction head and draw the solids entrained in a liquid flow into one or more outlets of the suction head; a manifold including a body having one or more inlets coupled to the one or more outlets of each suction head to permit the collected solids entrained in the liquid flow to pass into the manifold and one or more discharge ports configured to expel the collected solids entrained in the liquid flow from the manifold; and a pumping arrangement that draws in liquid and entrained solids from the suction head assemblies via the manifold and discharges the liquid and entrained solids via a discharge pipe.

A first game play area is provided on the front surface and includes a plurality of game symbols for play of a first game. A second game play area is provided on the back surface and includes one or more windows defined therein for play of a second game partially embodied on the back surface. A fold line indication on the front surface and divides the substrate into a first portion and a second portion. The second portion is foldable onto the first portion in a folded state of the substrate such that the front surface of the second portion is against the front surface of the first portion and the one or more windows align with the first game play area. The game symbols in the first game play area that are visible to a player through the one or more windows in the folded state of the substrate determine an outcome of the second game.

Abstract: Embodiments relate generally to systems and methods for preventing arcing within a snap action switch, particularly by removing a portion of a contact carrier attached to a stationary contact. A method of forming a contact for use in a snap action switch may comprise welding a contact onto a contact carrier; trimming at least one edge of the contact carrier proximate to the contact; and installing the contact carrier into a snap action switch housing. Trimming the at least one edge of the contact carrier may also comprise removing flash formed during the welding of the contact to the contact carrier.

Abstract: A battery pack for use with a motorized architectural structure covering is illustrated. The battery pack includes a battery tube, and first and second end caps. The battery tube may include a valley portion located between first and second battery cavities for receiving first and second rows of batteries. The second end cap may include one or more projections (e.g., first and second tabs, handle, etc.) to facilitate removal of the battery pack from mounting clips associated with the motorized architectural structure covering. The removable, second end cap may include first and second release buttons extending into the valley portion. The release buttons may have a wider portion adjacent to the second end cap, and a narrower portion extending at least partially into the valley portion. The release buttons preferably include a tapered, for example, triangular, or trapezoidal shape, to extend into the valley portion for facilitating user engagement therewith.

Abstract: A support structure is used to mount the stator of a rotating electrical machine (e.g. a motor or generator). The support structure includes a rigid external support frame (6). To minimise the transmission of vibrations caused by stator electromagnetic forces into the external support frame (6), at least one sandwich anti-vibration mount (14a) is secured between the external support frame (6) and a part of the stator (28). The mount (14a) is oriented relative to the stator such that it experiences compression loading in a substantially tangential direction of the stator and radial shear loading in a substantially radial direction of the stator during operation of the rotating electrical machine. The sandwich anti-vibration mount (14a, 14b) is pre-loaded with a pre-determined compression load substantially along its compression axis (Ac).

A plurality of pole bodies are independently mounted circumferentially around the rotor by a pole mounting arrangement.

Abstract: The present invention relates to a retaining band which provides outer reinforcement for the rotor assembly of a high speed electrical machine. The rotor assembly includes a plurality of circumferentially-spaced permanent magnet assemblies. A retaining band is fitted around the rotor assembly and applies a pre-load to the permanent magnet assemblies in the radial direction. The retaining band has a plurality of voids that are sized and shaped to provide the retaining band with a progressive spring stiffness in the radial direction. The voids are open before the retaining band is fitted and during the fitting process the retaining band is deflected in the radial direction so that the voids close up and the retaining band becomes substantially solid.

Abstract: Monitoring the condition of an anti-vibration mount, e.g. a sandwich mount in which a plurality of elastomeric layers are interleaved with rigid plates. A set of effectiveness data is determined using input and output data measured or derived over a period of time. The effectiveness data is indicative of the effectiveness of the anti-vibration mount, in particular is dynamic stiffness. The input data is indicative of the amplitude of input vibrations that are applied to the anti-vibration mount and the output data is indicative of the amplitude of corresponding output vibrations of the anti-vibration mount (e.g. the vibrations that are transferred into an external support frame of the associated apparatus or equipment). The operating condition of the anti-vibration mount is monitored using the set of effectiveness data, e.g. by comparing successive sets of effectiveness data determined using input and output data collected over different time periods.

Abstract: A torsional vibration damper is integrated into a rotating electrical machine. A rotatable assembly of the electrical machine includes a rotor core pack having a first end and a second end, The integrated torsional vibration damper consists of a torsional elastic coupling and a torsional elastic damper and provides mechanical damping. The integrated torsional vibration damper is mounted to the rotatable shaft of the electrical machine by a flange. The rotor core pack is mounted at the first end to the integrated torsional vibration damper by suitable structure members such as a mounting flange and is not fixedly mounted directly to the rotatable shaft. In the case where the rotor core pack is cooled by circulating coolant fluid (e.g. MIDEL) then the integrated torsional vibration damper may be a viscous damper that uses the coolant fluid as a viscous working, fluid.
