Abstract: A method of preserving frequency components in digitally sampled signals exceeding a maximum frequency related to a predetermined digital sample interval. The signals correspond to a plurality of sensors positioned at spaced apart locations, and the signals from each of the plurality of sensors are digitally sampled at the predetermined digital sample interval. The method includes the steps of determining time adjustment values corresponding to each sensor which provide amplitude correspondence between each of the signals generated by each of the sensors in response to different propagation times of energy from an energy source to each of the sensors; adjusting a time of acquisition of each digital sample from each of the sensors by applying the corresponding time adjustment value to generate time-adjusted samples; and combining all the time adjusted samples into a combined output signal having a sampling time interval smaller than the predetermined digital sample interval.

Abstract: An integral ground lug assembly for a dynamoelectric machine in the form of a motor is provided which permits quick attaching for a ground wire. The assembly includes a lug integrally formed with an end-shield of the motor. The lug extends radially from the end-shield and has both an axially extending bore and a radially extending bore which intersect one another. In addition, the lug may incorporate a transverse bore intersecting the axial bore. A clip is received in the axially extending bore and interacts with the bore to prevent movement of the clip relative to the bore. This maintains the clip in place during shipment and thereafter. A fastener extends through the radial bore to press the clip legs together to pinch or hold the ground wire in place. The clip operation within the lug may be varied so that ground wire attachment may be made from a number of directions, depending, for example, on the applicational use of the matter.

Abstract: A valve body pressure formed from pipe components includes an annular portion for receiving a ball closure member. A pair of conduit portions are connected to the annular portion and the ball. A stem housing for rotatably supporting a valve stem extends up from the annular portion. The stem housing, annular portion, and conduit portions are welded to form the unitary valve body. The conduit portions are integrally connected to end fittings adaptable to connect identical or different grades of polyethylene pipe or metal pipe to polyethylene pipe. The internal surface of the conduit portion includes gripping teeth and O-ring seals that frictionally and sealingly engage the surface of the polyethylene end fitting. The valve can include a metal end fitting and a polyethylene end fitting. The polyethylene end fitting is connected by butt fusion or electrofusion coupling to polyethylene conduit, generally 6 inches in diameter or larger for use in a natural gas distribution system.

In one aspect fuel fluid, liquid or vapor is injected into an intake (e.g.

Abstract: A baffle and lead guide is provided for an electric motor with a reverse air flow cooling system for the motor. The motor includes a shell housing a stator assembly and a rotor assembly, the rotor assembly including an axially extending shaft. A first end shield closes one end of the shell and a second end shield closes the second end. The shaft is rotatably journaled in at least one of the first and second end shields and extends through at least one of the first and second end shields. A fan is fixed to the shaft between the rotor and the second end shield to rotate with said shaft. Leads extend to the second end shield through the motor shell from the stator assembly. The baffle is positioned axially adjacent the fan. Preferably, the baffle is annular in shape and includes at least one axially extending leg which defines a lead chute radially outboard of the fan to guide the lead wires past the fan.

Abstract: A gas cylinder valve with minimum wetted area has a one-piece valving assembly comprising a valve member, a non-perforated diaphragm member and a valve stem, the latter including a threaded stud and a stem shaft threaded on to the stud. The threaded stud, diaphragm member and valve member are fused together by a YAG laser weld applied through a central, blind bore in the valve member. Another through weld is applied around the peripheral edge of the threaded stud. A rim on the stem shaft clamps the diaphragm outside the peripheral weld through a pair of washers which absorb the torsional load. A helical compression spring bears on a valve stem shaft shoulder outside the wetted area to bias the valve open. A resilient bushing supported by a metal cup backs up the diaphragm member.

Abstract: A multi-function fluid flow monitoring apparatus capable of measuring fluid flow-related variables of fluid in a channel on the basis of signals from any one or more of a plurality of different types of flow sensors. Such different types of flow sensors may include, for example, a bubbler-type pressure sensor, a submerged pressure transducer, an ultrasonic transducer, and/or a velocity sensor forming part of an area-velocity sensor system, each of which sensors may be selectively connected to the apparatus as needed to accommodate various monitoring conditions. The apparatus is further capable of monitoring various conditions of fluid in the channel, such as pH level, ORP, temperature, solution conductivity, dissolved oxygen, and the like.

Abstract: A printing plate with a mesh material, a removable substrate, a substrate, and a paper backing on said substrate. The mesh material has interstices and has first and second surfaces. The substrate is adhered to one of the first and second surfaces of the mesh material and forms a well defined at its bottom by the substrate and at its sides by the interstices of the mesh material, wherein the well receives and stores pigment for printing. Multiple colors of pigment may be stored simultaneously within the wells of the printing plate, thereby enabling those multiple colors to be printed concurrently in a single printing pass operation.

Abstract: A bracket of the present invention is for use with a capacitor motor having a stator and at least one end shield. The motor end shield has a side wall the bottom of which is spaced axially upwardly and radially outwardly from an axially outer face of the stator to define a gap. The bracket has a base, a pair of legs extending upwardly from the base to snappingly receive the capacitor, and a tab which is received in the gap to secure the bracket to the motor without the use of fasteners.

Abstract: The present invention discloses a wireless LAN, a peer-to-peer wireless LAN, a wireless transceiver and a method of transmitting data, all of which are capable of operating at frequencies in excess of 10 GHz and in multipath transmission environments. This is achieved by a combination of techniques which enable adequate performance in the presence of multipath transmission paths where the reciprocal of the information bit rate of the transmission is short relative to the time delay differences between significant ones of the multipath transmission paths. In the LANs the mobile transceivers are each connected to, and powered by, a corresponding portable electronic device with computational ability.

The ballast has a substantially flat backwall, attachment devices for rigidly attaching the ballast to a support, and electrical connectors for connecting to an electric current source. The backplate has a forward surface rigidly attached to the backwall of the ballast. The socket is attached to the forward surface such that the fluorescent light tube extends substantially perpendicularly away from the forward surface, above a part of the ballast which is not covered with the socket.

Abstract: A grease collector housing is mounted directly atop a filter-containing kitchen exhaust hood at the exhaust collar. The housing includes a liquid reservoir at the bottom, a 360 degree shallow conical spray head immediately above the reservoir, an array of baffle-type grease filters above the spray, a filter-cleaning spray head above the array and a connector above it to the exhaust duct.
