Abstract: A covered conduit box includes a cover which maintains screws, used to fix the cover to a base member of the box, captive, when the cover is disengaged. The cover includes stepped screw bores therein which allow the screws to cock slightly relative to the cover, to engage in mating channels provided in flanges on the base member, the flanges being angled away from the cover to provide a torque upon the screws, maintaining engagement between the cover and the body. The stepped screw bore maintains the screw captured within the bore unless pressure is applied against the end of the screw to cause a thread thereof to interact with sidewalls of the bore, at which point the screw can be disengaged from capture therein.

Abstract: A motor assembly has a lead guard detachably disposed within a housing adjacent a conductor receiving opening formed therein. The lead guard defines a space within the motor housing into which a conductor may be routed. The guard has a generally flat portion and an upstanding portion connected at an angle thereto that extends around three of four perimetral edges of the flat portion. A mounting mechanism is provided to position the lead guard within the housing of the motor. A guide mechanism for guiding conductors fed through the conductor receiving opening into the space defined by the lead guard may also be provided. This guide mechanism may be attached to or integrally molded with the generally flat portion of the lead guard and may include an angled/ramped portion, the edge of which abuts the inner surface of the housing below the conductor receiving opening to prevent conductors from entering the motor housing and coming in contact with rotating components disposed therein.

Abstract: A motor assembly has a stator and rotor housed within a frame. An end shield is attached to one end of the frame for rotatably supporting a shaft extending therethrough. A fan is mounted to the shaft adjacent the end shield. A fan cover is mounted to the end shield and about the fan in a snap-fit manner. The end shield includes a front face and an annular side face, and has a plurality of slots formed in the annular face. The end shield also includes a boss adjacent each slot, which is formed to include at least one bearing surface and a ramp thereon. The fan cover includes a plurality of mounting brackets spaced about its inner periphery and extending outwardly toward the end shield. Each mounting bracket has a projection thereon, which is receivable within the slot on the annular face of the end shield. Each bracket also includes a backstop with a crushable rib thereon.

Abstract: Method for deposit of a p type dopant from a dopant layer into a predetermined region of a III-V semiconductor layer or multiple layers. The p type dopant is deposited in very high concentration in a semiconductor layer adjacent to the predetermined region. A second semiconductor layer, doped with a lower concentration of an n type dopant, is later deposited so that the high concentration p type dopant layer lies between the predetermined region and the n type dopant layer. The p type dopant is diffused into the predetermined region by thermally driven diffusion, which may be carried out at a lower temperature or for a shorter diffusion time interval than with conventional diffusion, and p type dopant diffusion may extend over greater distances.

Abstract: A positive displacement fuel injection system for use with a combustion engine including a fuel pump (10,10') which forms and delivers pre-metered slugs of fuel and timing fluid to unit injectors (300,300') associated with the engine combustion chambers. The pre-metered slug of timing fluid has a prescribed volume and sets the timing advance for the unit injector. The fuel pump can vary the size of the pre-metered slugs of fuel and timing fluid on a cycle-by-cycle basis.

Abstract: An intermittent motion horizontal packaging machine in which pouches made one at a time by a pouch making section operating at a high index cycle rate are filled two at a time while being advanced in a single row by a pouch filling section operating at one-half the index cycle rate of the pouch making section.

Abstract: A collar fastener for bringing the two tapered sides of a shirt collar together wherein the fastener hooks into the under-surface or back surface of the collar on each side. The fastener fits unobtrusively under the necktie so as to make it substantially invisible to others. A spring disposed between the arms of the fastener serves to apply spring pressure.

Abstract: Flexible pouches filled with product are gripped at their side margins by bag clamps and are advanced to a steaming station where steam is directed downwardly toward the pouches to drive air therefrom. As the steam is being introduced into each pouch, the pouch is held in a widely open position by the clamps. Thereafter, the pouch is closed by shifting one clamp away from the other clamp and then is sealed by heated sealing bars. To enable a substantially wrinkle-free top seal to be formed, each clamp includes upper and lower jaws which grip the pouch above and below the bottom margin of the top seal to keep the seal area tight.
