Abstract: In Situ Re-Configurable Wireless Communications System (IRCWCS) in combination with a wearable computer provides an individual user at a public gathering place, fixed facility or non-stationary object with new and enhanced capabilities. In one embodiment of the invention, the re-configurable wireless communication system includes a portable wireless access unit and a Long Range Ethernet (LRE) network switch that connects to an existing LAN. A bridge device such as an LRE puck connects the portable wireless access unit to the LRE network switch through a communications infrastructure. A wearable computer in wireless communication with the portable wireless access unit using a radio frequency link allows communication of video, voice and data to and from the existing LAN through the LRE network switch. The LRE network switch couples to a central command station through the existing LAN.

Abstract: An apparatus and method for using a wearable computer in testing applications that uses a probe, a display, an audio communication device, a computer adapted to receive data from the probe, exchange data with the display, exchange data with the audio communications device, and exchange data using wireless communication, a battery, and a harness for securing the probe, display, computer, and battery to a person's body.

Abstract: A fault protection system whose trip logic considers power magnitude and direction at first and second points on a conductor is provided. Under normal operating conditions, power flows in the same direction through first and second points on the conductor. Under faulted conditions, a differential power condition exists; that is, the power flowing at a first point on the conductor is of different magnitude and/or direction than the power flowing at a second point on the conductor. The trip logic identifies the differential power condition as the result of a fault between the first and second points on the conductor and causes a protective device on each side of the fault to trip open, thus isolating the fault.

Abstract: A watertight door apparatus includes a door, a door frame, a number of dogging elements, and an actuator mechanism for toggling the dogging elements between a latched condition and an unlatched condition. The dogging elements include roller elements for reducing friction between mating parts. A detent mechanism is provided to prevent inadvertent operation of the actuator mechanism. The dogging elements can be configured to rotate into and out of the latched condition, or they can be configured to slide into and out of the latched condition.

Abstract: The present invention discloses a material handling system including a loading conveyor, a material processing conveyor, a cutting instrument, and a water table operably associated with the material processing conveyor. The material processing conveyor includes an endless belt having first and second sprocket chains and a plurality of support members extending therebetween. The ends of the support members are connected to the corresponding sprocket chains via U-shaped connectors. The water table is maintained in the storage position while the processing conveyor is operating. Once movement of the processing conveyor has ceased, the water table is raised to an operating position so that the by-products of the cutting operation will be collected therein. The U-shaped connectors receive the side walls of the water table E. The U-shaped connectors obviate the need for elaborate end wall systems which are extremely expensive and time consuming to operate.

Abstract: A compact wire feeder and arc welding control unit including, a portable housing having a base portion, a side portion and a removable cover portion. A wire feeder is included in the unit, for feeding filler metal wire or the like, and is disposed within the housing proximate one side of the housing so that when the removable cover portion is removed, the wire feeder is easily accessed by the operator. A gas line is positioned on a second side of the housing opposite the wire feeder and has with it a gas line valve. A feed wire motor for driving the wire feeder is disposed intermediate the gas line and the wire feeder. A circuit board is disposed above the motor intermediate the gas line and the wire feeder. A wire real housing is fixed to the side portion of the housing and communicates with the housing so that wire may be fed of a real in the real housing and fed into the wire feeder.

Abstract: An insulating device is disclosed as suitable for encasing and supporting a welding torch. The device is L-shape when finally assembled being formed by two T-shape panel members of closely woven fabric material. These panels are stitched along their contiguous edges and then folded to form an L-shape pouch or glove for the torch, the folded sections being held by heat conductive rings which serve to conduct heat from the stitching material. The folded sections are arranged to provide a corner opening for permitting the ingress and egress of the torch to the interior of the device.

Abstract: An alignment mechanism for punch presses and the like, comprising a base having an upper support surface; the upper support surface having a plurality of load oriented spaced shaped recesses; a base alignment sleeve positioned in each of the recesses and conforming thereto and extending upwardly above the upper support surface; a frame positioned on the upper support surface and having a portion extending upwardly therefrom; the frame having a first set of a plurality of load oriented spaced shaped recesses for cooperating with the plurality of base recesses for positioning the alignment sleeves in the first set of recesses for aligning the frame with the base; the upwardly extending portion of the frame having an uppermost surface; the uppermost surface having a second set of a plurality of load oriented spaced shaped recesses; a crown alignment sleeve positioned in each recess of the second set of recesses and conforming thereto and extending upwardly above the upper row surface; a crown positioned on the u

Abstract: In a fly wheel power press having a rotatable drive shaft mounted in a housing and with an H-shaped yoke to which pivot pins are mounted and from which a pair of clutch shoes and brake shoes depend, an adjustment mechanism having a knurled portion on the pin and a cooperating knurled aperture in a lock plate which is in sliding engagement with the knurled portion of the pin so as to permit securement of the lock plate, and thereby the clutch and brake shoes, in a pre-selected adjusted position to one of the uprights is disclosed.
