Abstract: An arc quenching device includes a frame, at least one controlled-arcing device supported by the frame, and at least one contact assembly supported by the frame and electrically connected to the at least one controlled-arcing device. The device further includes a racking mechanism supported by the frame and including a motor and at least one actuator member driven by the motor and configured to engage a feature in an electrical equipment unit compartment to move the arc quenching device within the compartment and engage the at least one contact assembly with a bus of the electrical equipment unit. The arc quenching device may be configured to be installed in a cassette in the electrical equipment unit and the actuator member may be configured to engage a feature of the cassette.

Abstract: A test apparatus includes an output configured to be coupled to a sense input of an arc quenching device control circuit of an arc quenching system, a user interface, and a control circuit configured to generate a simulated sense signal at the output in response to an input at the user interface, the simulated sense signal representing a physical state associated with a fault condition of a bus coupled to the arc quenching system. The simulated sense signal may be configured to cause the arc quenching device control circuit to trigger an arc quenching device of the arc quenching system. The physical state may include, for example, a voltage condition, a current condition, a temperature, a pressure or a light intensity. In some embodiments, the simulated sense signal may include a current indicative of a current passing through a bus to which the arc quenching system is connected.

Abstract: An airlift pump comprising a hollow, cylindrical main body having an injection hole near the bottom end, a channel routed in the outside surface of the main body and extending continuously from the injection hole to the top end, and an air tube seated in the channel and bonded to the main body. The air tube comprises an injection end having an elbow forming an injection angle such that the air is injection into the main body in a downward direction toward the bottom end. The air tube further comprises a receiving end extending past the top end of the main body and connecting to air supply tubing. The pump has a restricted lateral width enabling the pump to fit inside the narrow monitoring wells typical in the groundwater monitoring industry.

Abstract: Generally stated, the present invention provides a glove which can be used in playing the game of golf. In desired arrangements, the glove can include a control-strap which is operatively affixed to the back-side surface of the glove. The control-strap is configured to extend around a handle or grip-end of a golf club, with at least a portion of the control-strap configured to extend along the heel region of the glove and contact a thumb-side surface of the grip-end of the golf club. In other aspects, the glove can include first and second indexing lines which are located on the palm-side surface of the glove and delimit a finger-alignment area therebetween. Additionally, a grip target-region can be operatively designated on the palm-side surface of the glove.

Abstract: A current mortgage price indicator futures contract (“Mortgage Futures Contract”) that can be traded on a futures exchange is described. The contracts add value over existing hedging and speculating alternatives by meeting the needs of a wide range of mortgage and mortgage-backed securities (MBS) market participants such as portfolio managers, dealers, hedgers, originators, speculators and arbitrageurs. The Mortgage Futures Contract is based upon conventional MBS and has a relatively current coupon composition, thereby resulting in risk properties that appeal to market participants more so than prior contracts based on non-conventional MBS that were not correlated to current MBS production. The Mortgage Futures Contract has a cash settlement feature designed to eliminate complicated and largely uneconomic physical delivery of the underlying security. A options contract corresponding to the Mortgage Futures Contract and that can be traded on a futures exchange is also described.

Abstract: An apparatus and methods for measuring and supporting the cervical curve include a tool comprising a plurality of predetermined curves each substantially complementary in shape to a cervical curve, for measuring a person's cervical curve when the tool is positioned adjacent the nape of the person's neck. The tool comprises a predetermined size range of curves for allowing measurement of variously sized cervical curves. An embodiment of the tool includes a plurality of cards having a predetermined curve positioned along the edge of the card, for positioning adjacent the nape of the person's neck to measure the cervical curve. The method includes providing a cervical support pillow having dimensions substantially corresponding to the cervical curve measurement.

Abstract: Disclosed are tools and methods for assisting in the manual insertion of a needle into a medical device implanted under the skin of a patient and for assisting in the manual removal of the needle from this implanted medical device. The same tool may be used for both accessing and deaccessing the needle, or a special tool may be used for just assisting in the insertion of the needle into the implanted medical device. This special tool includes a holder section with a pair of fork elements spaced apart a distance which is slightly greater than the width of the implanted medical device. The tool for assisting in the manual removal of the needle from the implanted medical device includes an elongated body having a handle section and an enlarged guard section with an elongated slot extending from an edge of the guard section into the guard section, terminating at an internal portion of the guard section.

A plurality of equidistantly spaced radially extending grooves are formed in the end face of the inboard section of the hub forming a plurality of radially extending pulse teeth, a sensor detects the rotation of the pulse teeth and provides this information to a logic unit of the ABS system.

Abstract: Improved techniques are provided for separating mixtures of materials having different densities. The apparatus of the present invention is well suited for separating oil from water, and includes a separation tank defining a cylindrical water inlet chamber and a frustroconical separation chamber spaced above an adjoining the input inlet chamber. An oil leg is spaced above the separation chamber, and an adjustable oil overflow unit is provided adjacent the oil outlet for controlling the height of oil in the oil leg. A water leg is provided in parallel with the separation tank, and the elevation of the water outlet controls the height of water in the water leg. The oil leg overflow unit allows the head pressure in the oil leg relative to the head pressure in the water leg to maintain the interface within the separation chamber. Sensing devices are provided for monitoring the elevation of the oil/water interface within the separation chamber.

Abstract: A drill for a paper drilling machine. The drill is made of two separate parts, namely a cutting bit of hollow generally cylindrical form having an annular cutting edge at one end, and a hollow cylindrical sleeve which receives the opposite end portion of the bit and which is itself received in a collet assembly of a drill spindle of the machine. The sleeve is radially compressible and is compressed by the collet assembly to frictionally grip the bit and permit transmission of drilling torque from the drill spindle to the bit in use.
