Abstract: A method and system for interconnecting a telephone system and an intercom system. In one exemplary embodiment, telephone switchgear is connected to a telephone interface which provides separate voice transmit and receive channels. For example, an E&M tie line module can be utilized, which also includes E&M signaling connections for signaling an incoming intercom call to a telephone and for signaling an outgoing telephone call to an intercom. In this exemplary embodiment, an interface circuit is also provided to allow for signal level adjustment along the transmit and receive channels, such that the signal gain of the telephone system can differ from the signal gain of the intercom system. The interface circuit can include a controller which controls a switching device for selectively allowing communication along the transmit and receive channels during periods when communication is desired.

Abstract: Automated testing of versioned information handling system applications is performed by automatically compiling currently available versions at regular time intervals throughout a development cycle and then automatically testing each compiled version on test information handling systems to detect errors associated with each compiled version of the application. For instance, production operating systems used to configure manufactured information handling systems are automatically tested at regular intervals during development so that versions of a complete operating system and application environment are properly integrated. Testing of the complete operating system and application environment of a production operating system is accomplished by interrupting power to test information handling systems and loading the production operating system with a PXE agent. Periodic compilation and testing of versions provides simplified identification and tracking of development errors.

Abstract: A conveyor system for delivering items between a processing station and a remote delivery station includes a pair of flexible drive members and a pair of spaced apart drive guides each positioned to define a path of travel for one of the drive members between the stations. A carrier member having an item receiving portion and upper and lower ends is attached to both of the flexible drive members adjacent one of its upper or lower ends for reciprocation between the stations along the guides. A third flexible stabilization drive member and a corresponding stabilization guide is positioned to define a third path for the stabilization drive member. The carrier member is attached to the stabilization drive member adjacent to the other of its upper or lower ends. The active stabilization guide member provides for more uniform and stable translation of the carrier member between the stations.

Abstract: In a method for automatically naming hosts, a cluster controller receives unique identifiers (UIDs) from multiple hosts. In response to receiving the UIDs, the cluster controller causes the multiple hosts to produce ready signals. The cluster controller then receives user input (e.g., an indication that a floppy disk has been inserted into a floppy disk drive) from a first host among the multiple hosts. In response to receiving the user input from the first host, the cluster controller associates a first host name with the UID for the first host. The cluster controller then causes the first host to produce a completion signal. The cluster controller then receives user input from a second host among the multiple hosts. The operations of receiving replies from hosts, associating host names with UIDs, and causing hosts to produce completion signals may be repeated until each of the multiple hosts has been named.

Abstract: An apparatus for removing a fastener includes a main body portion. The fastener secures a first panel and a second panel and includes a retaining portion extending substantially through an aperture in the second panel. The retaining portion has a pair of resilient legs. Each resilient leg has a free end. The main body portion of the apparatus defines a slot. The slot has a open end and a closed end. The slot preferably tapers from the open end to the closed end. The slot is adapted to compress the free ends of the resilient legs together in response to translation of the fastener from the open end toward the closed end.

Abstract: A flexible drive tape conveyor system for conveying items between at least two spaced apart stations includes a carrier member and at least one tape guide track having a tape guide. The drive tape is substantially inflexible in a direction transverse to its width, and is at least partially housed in the tape guide. At least a portion of a tape guide track and tape guide are twisted about their longitudinal axis so that the drive tape and its affected carrier member can be turned in a direction transverse to the width of the drive tape. A drive mechanism is used to selectively reciprocate the drive tape and the carrier member between the spaced apart stations.

Abstract: A modular transaction station, comprising a frame; a monocoque counter assembly secured to the frame; and a pair of mounting sleeves extending about at least a portion of the periphery of the frame. The first mounting sleeve is secured to the frame, and the second mounting sleeve is securable to at least one of the frame and the first mounting sleeve, such that the transaction station may be secured within an opening in a wall with a portion of the wall bounding the opening positioned between the first and second mounting sleeves.

Abstract: An improved transactional drawer and method for reciprocating the drawer relative to its housing and opening the customer door in a sequential multi-stage manner. The drawer assembly preferably comprises a housing, a drawer and a customer door, wherein the drawer is free to reciprocate relative to the housing by interaction of a rail and corresponding slot guide track arrangement. A low powered reversible power source selectively reciprocates the drawer relative to the housing, a cam actuator, and the interaction of a cam actuator and follower arrangement mechanically moves the customer door between pre-determined opened and closed positions in a sequential multi-stage manner in response to the reciprocation of the drawer.

Abstract: A dynamic braking circuit for use with bi-directional conveyor systems and other equipment having a soft start/hard stop capability in both directions of movement. The circuit electrically brakes the rotation of a DC motor by short-circuiting the armature of the motor, thereby creating a reverse current and reverse magnetic field to oppose the motor's rotation. The circuit uses high-voltage, high-current SCR's to switch the motor running current (in both directions) and to brake the motor as quickly as is possible for a braking circuit that uses such reverse current. The circuit thereby operates without the use of any in-series braking resistors or "smoothing" inductors which lower the magnitude of the reverse current. The SCR's are gated "on" in pairs per each half-cycle of the AC power supply, which enhances noise immunity of the overall SCR control circuit.

Abstract: A debris control system is provided for an electron-beam drilling apparatus having a chamber encompassing a drilling area and a calibration area.

Abstract: This invention relates to an all gas-loadable liquid injector. The gas-loadable liquid injector comprises an accumulator for containing a liquid and a propellant gas, a liquid delivery tube for insertion into a material to be treated by the liquid, and intermediate means between the liquid delivery tube and the accumulator. The intermediate means restricts the flow of liquid when the pressure in the accumulator substantially exceeds that in the delivery tube and allows a restricted flow of liquid when the pressure in the accumulator is substantially equal to or less than that in the delivery tube. The intermediate means has a flexible and collapsible tube extending into the accumulator from the bowels of the accumulator and a straight rigid tube having a free end. The free end of the rigid tube always lies at the lowest level in the accumulator regardless of the altitude of the injector so as to dip into any liquid in the accumulator.

A cog wheel surround includes an outer guide track having an inner cog race with an inner surface of a diameter slightly larger than the base diameter of the cog and spaced substantially parallel therewith. A pair of oppositely disposed peeler tips are situated adjacent the top of the cog wheel surround between the outer guide track and the cog wheel, each including a peeler edge which has an arcuate inner face extending from the edge at a non-parallel orientation relatively to the base surface of the cog.

Abstract: An air conditioning system has a refrigeration system that supplies a refrigerant to an evaporator coil enclosed in a chiller tank. A low temperature coolant in the chiller tank is then refrigerated by the evaporator coil. The coolant is then pumped from the chiller tank through a spiral wall pipe in an area to be air conditioned, removing heat by conduction, convection, and evaporative cooling, and returned to the chiller tank to be cooled and recirculated. The coolant in the chiller tank is maintained at a desired temperature by the refrigeration system. The temperature in the conditioned area is controlled by the temperature and flow of the coolant in the spiral wall pipe. A heating system supplies hot water to the above air conditioning system while bypassing the refrigeration system. Humidification and cleaning are achieved by an overhead pipe which is perforated, and water or cleaning solution is pumped under low pressure and dispersed down onto the spiral wall pipe.
