Abstract: ABSTRACT OF THE DISCLOSURE A  low  cost,  multipurpose  digital  integrated circuit  (IC)  is  used as  the  basic  building  block  in establishing a network communication system over a desired communication link.   The digital  IC can function as an addressable microcomputer  interface between  the network line and a remotely located microcomputer which may, for example,  comprise  any  microprocessor  based  controlled product.   In such mode, the digital IC's function is to take data from the network and pass it on to the remotely located  microcomputer  upon  command  from  the  central controller and to transmit data from the microcomputer to the central controller.  The digital IC may also function as a nonaddressable microcomputer interface between the central or master controller and the network line.  In such case the digital IC's function is to continuously take data from the central controller and place it on the network and take data from the network and pass it back to the central controller.   The  digital  IC  may  also  function  as  an addressable load controller associated with an individual remote controlled device and responding to shed or restore load commands from the central controller over the network line.  When so used the digital IC may also be commanded to transmit a reply message back to the central controller giving  information  as to the status  of the  controlled device, thus enabling the central controller to monitor large number of remotely located controllable devices.

Title: Polyphase electronically commutated reluctance motor
Inventor: HENDERSHOT JAMES R
IPC: H02K19/10
Filed: 1989-04-24
Granted: 1992-05-05
Abstract: ABSTRACT    A motor structure and energization scheme provides a high efficiency electronically commutated reluctance motor that is characterized by less iron losses than conventional switched reluctance motors. Preferably, the motor operates without the reversal of the flow of flux in the member of the motor supporting the motor windings (e.g., the stator).  Also, the flux switching frequency in the first member is reduced and preferably minimized.  By eliminating flux reversals and minimizing the flux switching frequency, the electronically commutated reluctance motor is operable over a wide range of speeds with improved efficiency.  Structurally, first and second members of the motor are mounted for relative movement.  The first member includes unevenly spaced teeth, whereas the second member includes evenly spaced teeth.  The teeth of the first member are grouped into pairs separated by a space related to the even spacing of the teeth on the second member.  Adjacent pairs of teeth on the first member are separated by a spacing which is not equal to the spacing between the teeth of a pair.  To provide for relative movement of the first and second members, each pair of teeth on the first member are polarized to form poles of opposite polarity such that a magnetic circuit is formed joining the two adjacent teeth of the pair.

Granted: 1993-04-13
Abstract: 25,950 ABSTRACT OF THE DISCLOSURE            A container closure comprises a cylindrical molded uni-tary member defining a top panel and a skirt depending from the top panel to an open end for securement to the container, the skirt being interiorly tapered at the open end.  The taper begins flush with the outer surface of the skirt and ends in a first circum-ference extending radially of the central axis of such cylinder.          The skirt further defines a bead extending radially interiorly of the skirt to a second circumference radially closer to the cylinder central axis than the first circumference.  The closure provides sealing retention pressure in accordance with the radially interior extent of the bead and exhibits evidence of an initial removal from the container.  In one embodiment, the bead is generally of semi-spherical configuration and flow passages may exist in the bead, preferably over less than the hemispherical extent thereof.  The method for making the closure involves the use of a stripper plate to participate in part in defining a mold cavity.

Abstract: ABSTRACT OF THE DISCLOSURE A lamp replacement tool which provides for positively captivating lamps for ease of removing or inserting lamps from or into the type of a lamp housing that forms part of a flush mounted push button switch used in aircraft cockpit control panels.  The lamp is mounted behind a display legend formed on the face of the push button and for lamp replacement the push button portion of the switch unplugs from switch body and hinges down to expose the rear of the lamp.  A friction fit maintains the lamp in the lamp housing.  The lamp replacement tool includes upper and lower blades extending from a handle member in spaced apart parallel relationship.  The lower blade is formed with a forked end portion having a u-shape for engaging with a flange formed on a base portion of the lamp and for embracing the base portion.  The upper blade is formed with either a v-shaped portion or an aperture for engaging with a base contact protruding from one end of the lamp.  The upper blade terminates in an angled lead-in.  The lead-in provides a smooth surface for sliding over the base contact as the upper blade flexes over the base contact when the tool is pushed into engagement with the lamp.  The lamp is locked or captivated between the upper and lower blades of the tool when the u-shaped end of the lower blade embraces the base portion and engages with the flange and the interior surfaces of the v-shape or aperture portion of the upper blade engage the periphery of the base contact.

Abstract: A subscriber line access circuit for use in a telecommunications system is disclosed. The subscriber line access circuit includes a power supply bridge in the form of a first resistor inserted in the b-wire (ground potential side) of a subscriber line, a second resistor inserted in the a-wire (supply potential side) of the subscriber line, and a capacitor which bridges the two wires at the terminals of the two resistors on the sides thereof opposite to the respective potential sources. This supply bridge is coupled on the capacitor side with a two-to-four wire hybrid transformer for the two-wire/four-wire transition to the system and includes an evaluating circuit which delivers an indicating signal when the subscriber actuates a ground key. A cutoff circuit is arranged in the power supply bridge between the first and/or second resistor in that bridge and the respective one or ones of the transformer windings at the junction points at which the evaluating circuit is connected. The device for generating call signals is connected to one of these junction points via a coupling contact and a series resistance. The associated cutoff contact of the supply bridge and the coupling contact of the call signal generating device are controlled in such a way that they can be closed only alternatively.

Abstract: Structural joint for joining two elements (12, 14), the first element (12) having an elongate major tongue (22) of malleable deformable material and in one embodiment an elongate minor tongue (24), the second element (14) having an elongate protuberance in the form of e.g. curled tab (36). The major and minor tongues define an elongate recess adapted to receive the curled tab on joint formation. The major tongue (22) is deformed about the curled tab (36) to form at least a portion of an encircling curl which contacts the curled tab's external surface. When the elements are so joined, the gap between the major and minor tongues is less than the width of the curled tab, thereby precluding removal of the curled tab from the encircling curl. Prior to joint formation, the curled tab (36) is curled about a wire (37) which acts as a filler or support, and the joint will therefore be tight and solid. The inventive structural joint can preferably be used in ladders having rungs secured to side rails.
