Abstract: A cooling system for a combustion turbine transition section. The combustion turbine includes a compressor assembly with a compressed air bleed line, a combustor assembly, a transition section with integral cooling channels, a turbine assembly with integral cooling channels. The compressor assembly is coupled to the combustor assembly, the combustor assembly is further coupled to the transition section, the transition section is further coupled to the turbine assembly. The compressor assembly, combustor assembly, transition section, and turbine assembly form a flow path. The cooling device includes a compressed air steam generator, a feed water source coupled to, and providing water to, the compressed air steam generator, a steam pipe coupled to the transition section cooling channels and the compressed air steam generator. The compressed air bleed line passes through the compressed air steam generator. In operation, the compressor compresses the ambient air thereby raising the ambient air temperature.

Abstract: A control system is used with an associated mower having a cutting blade, a drive shaft for rotating the cutting blade, first and second drive wheels, and a power train for driving the first and second drive wheels. The control system has an electric clutch for selectively coupling the cutting blade to the drive shaft, first and second handles for independently driving the first and second drive wheels, first and second switches selectively switchable between first and second positions, a relay for electrically connecting the first and second switches to the electric clutch and control rods for mechanically connecting the first and second handles to the first and second switches. First and second handles are placeable into reverse positions. This causing first and second bell cranks to rotate about a control shaft which lifts first and second control rods. When the control rods are lifted, first and second switches are switched and power is disconnected to the electric clutch.

Abstract: A lock-down device for use in a circuit breaker assembly. The device comprises a base for releasably securing the device to the assembly's saddle, an arm portion connected to the base, and a hand portion, connected to the arm portion, for engaging the housing of a first circuit breaker such that when the first circuit breaker and a second circuit breaker is mounted on the saddle the hand portion is intermediate the first and second circuit breakers and the first circuit breaker cannot be inadvertently removed from the saddle. In an alternative embodiment, the hand portion of the device comprises flanges for engaging and permitting the lock-down of the second circuit breaker as well.

Abstract: An air flow structure for use in providing air to an engine mounted on an associated vehicle includes a hood for covering the engine, an air grill and connecting means for connecting the air grill to the hood. The air grill has a contoured cap, air inlet openings around the circumference and a discharge opening. The inlet openings are angled and are covered by the cap so that it is relatively difficult for rain or other unwanted substances to enter the engine.

Abstract: An improved grounding plate or contact assembly is provided for a photosensitive drum of an image forming apparatus such as a printer or photocopier. The arrangement ensures contact between the grounding plate/contact assembly and a contact area disposed on an interior surface of the drum regardless of the rotational orientation of the grounding plate/contact assembly with respect to the drum. In a preferred form of the invention, the grounding plate includes a plurality of circumferentially spaced contact members and is mounted upon a flange which is inserted into the end of the drum. Since the circumferential spacing of the contact members is less than a length of a laser scribed contact area on the interior surface of the drum, contact between the laser scribed area or patch and one of the contact members is ensured despite variations in the rotational or angular position of the flange with respect to the drum.

Abstract: A single belt drive system for a grounds care device using two transmission power units to provide directional drive to the wheels. The single belt arrangement allows the vehicle to have two identical transmission power units due to the asymmetric design.

Abstract: An oxygen management device adapted to mount on a post on a compressed oxygen cylinder. The device includes a manifold block which is attached to the oxygen cylinder post. A pressure regulator is mounted directly on and is integral with the manifold block for reducing the oxygen pressure to a desired level. The manifold block also mounts an overpressure relief valve, a solenoid operated flow control valve, a bypass valve, a continuous flow restrictor and a pressure gauge. The manifold and the components mounted thereon, a control circuit and a battery for operating the control circuit are mounted in an annular housing which has a central opening for receiving the oxygen cylinder post. The control circuit senses when a patient inhales in a nasal cannula and opens the flow control valve to deliver a predetermined dose of oxygen to the nasal cannula at the beginning of inhalation.
