Abstract: Methods are presented herein for a reduced state machine that describes nodes and relationship dynamics representing real network elements (networking devices and software processes) in a computer/data network, and abstracted logical items. Logical states of networking features of the network elements are reflected in the graph, while configuration data is stored for completeness. A method called a “Versioner Algorithm” is provided to record the temporal history of a node and its state over time within the node's metadata itself, while recorded relationships represent logical relations between observed nodes. A method is also provided to time-travel back to observe a historical view of the network. Further still, a method is provided to a difference of two historical topologies and return that data in human-readable or machine consumable form.

Abstract: An insulin management method is provided. The method includes providing an insulin delivery device, wherein the insulin delivery device is in the form of an automatic insulin delivery device attachable to a user's body for the duration of a fasting period.

Abstract: A flashback arrestor for use in gas cutting or welding equipment includes a porous body which defines a proximal end portion and a distal end portion and which has a plurality of pores. Each of the pores defines a pore size. The pore size is a function of a detonation cell size such that the pore size is increased to reduce a size of the sintered body.

Abstract: A golf bag cover comprising a body configured to contain a golf bag with a set of clubs therein. The golf bag having a carrying means (104; 106), the body (202) defining an elongate first aperture (212) through which the carrying means can extend. The closing means (214) arranged to substantially cover the whole of the aperture (212) with the carrying means extending through the aperture such that the golf bag fitted with the golf bag cover can be carried with the carrying means. The closing means is a plurality of flaps (214) each extending across the width of the aperture.

Abstract: A gaming system for playing a wagering game on a handheld gaming machine includes a handheld gaming machine configured to play the wagering game and an external system configured to regulate wagering game play on the handheld gaming machine.

Abstract: A submersible light (10) comprising a lens (12) sealed to the front of the reflector (20), a replaceable light source (22) housed in an aperture (25) in the reflector, a pressure member (30) positioned behind the reflector to define an air chamber (32) open at the base of the light but in sealed communication with the aperture whereby, in use, as the light becomes submerged liquid enters the base of the pressure member to pressurise the air within the pressure member to in turn form a pocket of pressurised air in the space between the lens and the reflector and thus prevent entry of liquid into that space.

Abstract: A computerized wagering game system has a gaming module comprising a processor and gaming code which is operable when executed on the processor to conduct a wagering game on which monetary value can be wagered. A video module is operable to display one or more gaming objects, and a background image. The one or more gaming objects have a degree of transparency so that the background image can be seen through the one or more gaming objects.

Abstract: A gas cutting torch has a body including an oxygen preheat tube having a first longitudinal axis and a fuel gas preheat tube having a second longitudinal axis. A head is connected to the preheat tubes having an oxygen passage communicating with the oxygen preheat tube, a fuel gas passage communicating with the fuel gas preheat tube, and an outlet for the flow of mixed gases from the torch. A mixing chamber in the head communicates with the oxygen passage and fuel gas passage. The torch has an orifice in the oxygen passage through which oxygen is adapted to flow to the mixing chamber at an increased flow velocity with an accompanying pressure drop. The pressure drop assists in the flow of fuel gas into the mixing chamber for mixture with the oxygen. A diffuser in the head defines a diffuser passage having an inlet region for receiving oxygen and fuel gas from the mixing chamber for flow through the diffuser, and an outlet region for the delivery of oxygen and fuel gas to the outlet of the head.

Abstract: A pneumatic oxygen conserver for providing oxygen to a patient. The conserver includes a body having a cavity and a main diaphragm dividing the cavity into first and second chambers. A first inlet passage delivers oxygen from an oxygen supply to the first chamber, and a second inlet passage delivers oxygen from the supply to the second chamber. An outlet passage delivers oxygen from the first chamber to the patient. The main diaphragm is movable between a closed position to prevent oxygen flow through the outlet passage and an open position to permit such flow. Vent passaging vents the second chamber. A pressure sensitive valve is connectable to the patient for permitting flow through the vent passaging when the patient inhales and preventing flow through the vent passaging when the patient exhales.

Abstract: A switchover valve for switching over from one supply of pressure fluid to another supply thereof in response to failing or failure of the one supply. The valve has a valve body having two inlets for connection thereto of the respective pressure fluid supplies and an outlet. A valve member is movable in the valve body between a position establishing communication for delivery of fluid from one inlet to the outlet and blocking flow from the other inlet to the outlet and a position establishing communication for delivery of fluid from the other inlet to the outlet and blocking flow from the one inlet to the outlet. The valve member is subject to pressure of fluid supplied to the one inlet for moving it from the first-mentioned position to the second-mentioned position and to pressure of fluid supplied to the other inlet for moving it from the second-mentioned position to the first-mentioned position.

Abstract: An integral gas regulator and flowmeter unit. The unit has a housing body with a high pressure gas inlet, a low pressure gas outlet, and a receptacle. A passage communicates gas to a valve seat in the receptacle. A differential pressure piston having seals at each end is slidably received within the receptacle and is spring biased away from the valve seat. A first end of the piston cooperates with the valve seat for controlling gas flow into the receptacle. A bore within the piston communicates gas from the first end to a second end of the piston. A floating inner flow tube mounted on the second end of the piston receives gas from the bore. A ball is slidably received within the inner flow tube. An outer flow tube overlies the inner flow tube. Both tubes are arranged for being positioned in a normally vertical position and may be marked with graduations for indicating the ball position.
