摘要： An apparatus and method is provided for introducing slack into a coil wire prior to termination. A stator having a volume of coil windings has a terminal board mounted thereon. Means for introducing slack in the coil wire includes a terminal receiving cavity located in the terminal board. A portion of the coil wire is passed across the cavity and a terminal is inserted therein, thereby crimpingly engaging the wire. The wire is simultaneously passed over a spacer which extends laterally across the cavity. When the spacer is subsequently removed a loop of slack remains in the wire.

摘要： A fan end bracket for a motorized fan assembly has a plurality of curvilinear tapered air passages. Each air passage includes a flow port, such that air being moved by a rotating fan assembly is directed through the air passages and the flow ports. A skeletal motor assembly is affixed to one side of the end bracket such that the motor shaft is disposed through a shaft aperture in the end bracket. A rotating fan member is affixed to the motor shaft adjacent to the other side of the end bracket. A shroud member is provided to shroud the rotating fan member so as to cause the flow of air to be directed through the air passages. A baffle plate is interposed between the rotating fan member and the end bracket. The baffle plate includes a plurality of curvilinear scallops which correspond to the air passages in the end bracket. An effective flow port is created between the scallops of the baffle plate and the tapered ramp surfaces of the end brackets so the size of the effective flow port may be adjusted by merely changing the baffle plate so as to optimize the flow and pressure parameters of the fan for a particular motor size.

摘要： A blower fan assembly is provided which includes a blower housing, an exhaust port having an air passage connected to the housing and an impeller assembly rotatably received within the housing. A sound attenuator is also provided to be received in the exhaust port. The attenuator includes at least one edge which extends into the housing to provide a gradual cutoff point. Air moving ahead of the rotating impeller vanes is partially redirected through the exhaust port by the attenuator. Remaining air is directed over and around the attenuator and is forced out of the housing at the cutoff point created where the exhaust port joins the housing. The redirection of air alleviates compression/decompression at the cutoffs thereby reducing the pulsing noise associated therewith.

摘要： A composite cartridge-type filter effective to substantially reduce low but hazardous concentrations of lead in drinking water to acceptable levels utilizes a porous activated carbon block filter and a powdered deionizing resin which is converted to an ion exchange resin in situ and during use of the filter. The method of operation of the filter results in a substantially extended life for lead removal as compared to similar disposable cartridge filters. The composite filter is also effective in removing dissolved metals which are leached from the soluble ash fraction of the carbon block itself. Powdered deionizing resin, having a greatly enhanced active surface area as compared to the resin beads from which it is formed, is formed by fracturing the resin beads in situ in a slurry filling and drying process which provides a stable packed resin bed.

摘要： A web of foam material is fed to a cutting station by upper and lower rollers drawing the web from a supply roll and along a low-friction table surface. A cutter station has a knife bar and blade, with a clamp bar coupled with the knife bar. The lower draw roller has its axle mounted in a pair of pivoted arms depressible by presser feet on a presser foot bar carried by the knife bar. When a desired length of web has been drawn past the cutter station, actuation of the knife bar lowers the blade toward a grooved anvil, while the presser feet swing the arms down to depress the lower roller away from the web to stop drawing it. Immediately after interrupting drawing action, the web is clamped by the clamp bar, and then immediately thereafter cutting occurs. The table has bridge-like fingers extending downstream through grooves in the movable lower feed roller. These fingers support the web when the lower roller is swung down. The cut sheets are conveyed through a static eliminator and then pass between staggered corrugation rolls for temporarily imparting longitudinal stiffness for enabling the temporarily corrugated sheet to be longitudinally projected through the air for dispensing into a desired position of utility, for example landing in the open top of a box packed with delicate items.

摘要： A by-pass vacuum motor assembly wherein the motor cooling fan is positioned in an opening at the bottom of the motor band and immediately above a flat plate portion of the fan housing bracket. The flat plate portion functions as a plate diffuser, redirecting air drawn through the commutator end bracket and across the motor internals into a radial exhaust between a bottom portion of the band and a top portion of the fan end bracket. The invention also includes a brush holder clip passing through a vertical opening in the commutator end bracket and engaging a collar on the brush mechanism. The brush mechanism passes through a horizontal opening in the commutator end bracket which intersects with the vertical opening. Armature grounding is achieved by a disk maintained in a recess in the commutator end bracket and urged by a spring against the bearing receiving the motor shaft. The power wires to the motor are secured by a tab maintained opposite an opening in the commutator end bracket which is itself opposite an opening in the band. Power wires pass through the openings and over the tab, being crimped thereby.

摘要： A fire fighting tool is described which is capable of both penetrating the wall of an enclosure, and dispensing a fire fighting agent into the interior of the enclosure. A drill bit or other penetrating device is carried at the forward end of an elongate shaft which is connected at its rear end to a drill motor or other appropriate actuating device. The shaft is surrounded by a barrel which receives a fluid fire fighting agent and includes a series of outlet openings at its forward end through which the agent is dispensed. The shaft is thus surrounded and cooled by the agent during the penetration operation. A leaky bearing is provided at the forward end of the barrel, and is specially configured along with the shaft and drill bit to induce a leakage of agent through the bearing and onto the bit and surrounding enclosure wall during drilling, thereby cooling the various parts and lessening the risk of an explosion. The barrel is designed to hold the tool in place once it has been inserted into the enclosure.

摘要： An optical fibre cable switch is provided in which opposed cable end faces are precisely aligned coaxially while permitting standard optical fibre cable bushings to be used. An alignment member is first positioned within the central opening of the bushings. The aligned bushings are then cemented or glued to the switch housing while being held in alignment by the alignment member. The alignment member is then removed so that standard cable terminating ferrules may be inserted into the aligned bushings.
