The present disclosure relates to gas turbine engine operation in which an igniter assembly is provided with an electrical energy input (e.g., an electrical waveform) that is configured to increase a likelihood of igniting a fuel-air mixture surrounding the igniter assembly. In certain embodiments, the igniter assembly is supplied with an augmented electrical waveform that may reduce a quantity of sparks generated by the igniter assembly before successful light-off (e.g., ignition) of the fuel-air mixture is achieved (e.g., as compared to a quantity of sparks generated to achieve ignition by an igniter assembly that receives an electrical energy input in the form of a conventional electrical waveform). Accordingly, the augmented electrical waveform may reduce wear (e.g., via oxidation) on electrodes of the igniter assembly, such as a primary electrode (e.g., a center electrode) and a secondary electrode (e.g., an outer shell electrode) disposed about the primary electrode.

A durable and wear resistant synthetic sports transition turf field having at least two strips with a plurality of fibrillated polypropylene strands tufted within a backing material. The strands are tufted in a wide variety of pile heights, patterns, gauges, and stitch patterns depending upon end use. The backing material consists of at least two layers of a woven material, with the bottommost one coated with a secondary coating used to contain the ends of the plurality of strands. The strips are placed onto a shock layer and coupled together using a hook and loop fastening system. The field is covered with an infill preferably consisting of resilient particles. The field is easily installed and removed and is ideal for use in indoor, multiuse sports and entertainment facilities that require a multitude of different flooring surfaces.

A drainage system for a synthetic sports field is disclosed that substantially prevents the leeching of specific contaminants from surface runoff water from entering into water tables or sewer systems associated with the drainage of the synthetic sports field. The drainage system includes a containment system and filtration system located beneath the synthetic sports field for directing rainwater through a series of drains and filters prior to being exposed to either the sewer system or water table. In this way, environmental concerns associated with the drainage of synthetic sports fields is alleviated.

A modular synthetic grass playing surface system formed from a plurality of modular units. Each modular unit has a synthetic grass layer placed upon predetermined sized pallets having a pre-installed elastomeric layer. A layer of resilient particle infill is optionally introduced to the top surface of the modular unit. A corrugated plastic sleeve is optionally installed around each formed modular unit while the modular unit is stored and moved. A plurality of modular units are then installed onto a relatively flat surface to form the playing surface in a desired shape and size.

A device for entering data into a computer and for manipulation of a cursor. The device includes a joystick, a conductive spring and at least one capacitive force sensor. The conductive spring is capable of being deflected by force applied to the joystick which is measured by the capacitive force sensor.

A sewage ejector system includes a basin and top cover. The basin body includes a generally cylindrical wall, a closed bottom, and an open top. Several features assist in installation, handling and/or performance of the basin. An annular collar projecting from the outer surface of the wall is useful for inhibiting flotation of the basin. Diametrically opposed recesses formed in the outer wall surface facilitate handling of the basin during transport and installation. A raised annular edge at the top of the basin body protects outer edges of the top cover.

A patient fluid collection system is disclosed which includes a fluid collection reservoir, a cover for the reservoir, and a port on the reservoir having a scalloped upper edge. The scalloped upper edge prevents the port from being inadvertently closed off in the event that a tube valve containing a flapper valve is improperly positioned on the port.

Suction canister system

A closure system includes a plurality of closure panels adapted to be moved between deployed and stowed positions. All on a pair of carrier tracks on opposite side of a building opening. The actuator in the deployed position have abutting top and bottom edges and parallel side surface that span across the building opening. The actuators in the stowed position have abutting in inner and outer side surfaces in parallel top edges and parallel bottom edges. The top and bottom edges maintain their top and bottom orientation as their closure panels transition between the deployed an stowed positions.

Closure system

A patient fluid collection system is disclosed which includes a fluid collection reservoir, a cover for the reservoir and a liner within the reservoir comprising an enlargeable or expandable wall portion such that the wall portion may expand if the liner fills with fluid. An anti-reflux system is also disclosed as well as a new tandem tube and a new connector.

A pump assembly having a hermetically sealed switch cavity for retaining a magnetically actuated mechanical switch. The assembly includes a housing having a motor cavity and an integral guide for cooperating with an external float assembly. A housing cover includes electrically conductive pins extending therethrough and is connected to the housing to substantially seal the motor cavity. A switch cover cooperatively engages a portion of the housing cover to form the hermetically sealed switch cavity. The switch cavity also encloses at least one conductive pin in the housing cover.

A process is provided for the removal of HCl and HF from a hot gas stream concurrently with the removal of sulfur compounds. The process involves the introduction of an HCl/HF sorbent such as nahcolite, sodium bicarbonate, sodium carbonate or Trona in powder form into the process stream at any one or all of four alternative locations in an amount sufficient to break down the HCl and HF into solid salts which are subsequently removed from the stream.

A drive system for the internal combustion engine of a large work vehicle, such as a self-propelled agricultural combine. The drive system comprising three concentric drive shafts that are housed in a housing for driving three separate usage assemblies. The outer and middle drive shafts are provided with bevel gear assemblies having output axes perpendicular to the drive shafts axis. The bevel gear assembly of the outer drive shaft is coupled to a series of four sequentially mounted hydraulic pumps, whereas the bevel gear assembly of the middle drive shaft is coupled to a forwardly extending drive shaft. An internal clutch is provided for operatively engaging and disengaging the middle drive shaft from the drive train.

Compact combine drive system

A rechargeable emergency portable battery charger for starter motor storage batteries. The device includes a sealed lead acid battery as a source of energy. An oscillator circuit connected to a transformer generates 3 V in its secondary. This voltage is rectified and added in series to the 12 V of the self-contained battery to provide charging current to a starter motor storage battery. Connection is made via a cigarette lighter socket in the disabled vehicle. Current is limited to approximately 4 amps so as to limit heat dissipation to a safe level. Furthermore, a voltage-sensing circuit determines if the voltage of the starter storage battery is below approximately 6 V or is shorted to ground. In either case, output current is further limited to the point of cut-off. Recharging the self-contained battery is made possible by a switch that connects the cigarette lighter of a running car directly to the self-contained battery of the charger. This switch also permits connection of any 12 VDC device directly to the self-contained battery. An ammeter monitors current flow in this power pack mode, as well as the charging and recharging modes. A light-emitting diode circuit indicates when the charging of the starter motor storage battery is complete.
