Abstract: A weather-resistant electrical connector having an environmental seal and including a locking assembly made from a high impact strength thermoplastic. A method is disclosed for overmolding the connectors in one step. A locking yoke latches the connectors together. Locking tabs secure the connectors to mounting plates. The locking tabs have steps to retain the connectors upon compression of a seal. An insulated mounting post supports the contact and is of sufficient length to seal and contain any arcs from live connections.

Abstract: A novel electrode and method of making the same. The electrode includes activated carbon that has been modified by treatment with an alkali solution and an acid, such as nitric acid, and then washed and dried. The carbon may then be annealed. The method of modifying the activated carbon helps produce an electrode with considerably higher electric capacity and stable electric characteristics. Additionally, the electrodes may be produced more quickly and inexpensively and, therefore, permits their production of electrodes that are used for superconductors.

Abstract: A method of formation and charge of a negative polarizable electrode of an electric double layer capacitor. The method can be used for manufacturing of high capacitance capacitors utilizing the energy of the electric double layer. The methods achieve hydrogen evolution on carbonaceous materials using very negative potentials. The methods provide an EDL capacitor, employing an aqueous electrolyte, with improved specific energy. The methods may also ensure the hermeticity of the capacitor. The methods include pretreating the electric double layer capacitor by keeping the negative polarizable electrode at a desired minimum potential prior to use. Desirably, the minimum potential ranges from about −0.25 to about −1.2 V vs. a reference hydrogen electrode.

Abstract: The invention relates to a tray for packaging portions of meat or similar foods that are stored and presented in refrigerated conditions. Said tray is deep-drawn from polystyrene or a similar foam material, and has a base and a peripheral side wall. Said base and said side wall have a liquid-impermeable skin on the inside and the outside. This skin has recesses on the inside of the base and the foam layer that is located between the inner and outer skin is at least partially open-celled and has the effect of absorbing liquid. At least one channel is molded in the inside of the base, said channel essentially completely surrounding a section of the surface of the base and having flanks and a channel floor which also have a liquid-impermeable skin. The flank which is oriented towards said section of the surface has at least one recess which allows the passage of liquid.

Abstract: A method and a system for providing a skewed clock signal which is used for latching a data signal received from a memory into a read-data latch. A control signal latch and a control-signal buffer provide a control sign to the memory. A read-data buffer feeds a data signal from the memory to a read-data latch, which is provided with skewed read-clock signal. A read-clock delay circuit provides a clock signal to the read-data latch, and delays the read clock signal a period of time approximately equal to the signal propagation delay time of the read data buffer and the propagation delay time associated with transmitting a signal from the output terminal of said control signal latch circuit to the control-signal input terminal of the memory.

Abstract: A cordless telephone employed in a public telephone system provides mobility and service at reasonable cost to users of portable communications equipment. The system includes a plurality of base units which are accessible by a plurality of similarly configured cordless telephones. Each one of these base units is assigned and operates on one of multiple frequency channels and each one of the cordless telephones is capable of establishing a communications link with each one of these base units. Once a cordless telephone establishes communications with a base unit within its reception range, other cordless telephones within this reception range are precluded from establishing communications with this base unit or monitoring or otherwise interfering with communications between the cordless telephone and this base unit while the communications link is established therebetween.

Abstract: A spread-spectrum signal which conveys identifying information for an associated information signal is superimposed on the associated signal and transmitted therewith. Such identifying information distinguishes between voice and data information signals and between different types of data information signals. Such identification can be used for a variety of purposes within a communications network, such as facility and equipment selection, equipment disablement and bypass, setting communications parameters, e.g., speed, and inhibiting communications upon fault detection.

Abstract: An arrangement for data conferencing either multiple computers (FIG. 1), or multiple terminals with a computer (FIG. 4), includes software (21;511) for communicating keystrokes from conference participants to an application program (22;550) that is the object of the conference, and for communicating display signals from the application program to the participants. In one embodiment (FIG. 1), a first program (23) executing on a first computer (PC 2) transmits first computer-generated keystrokes to a second computer (PC 1), and displays on the first computer images received from the second computer, while a second program (21) co-resident with the application program (22) on the second computer enters received first computer keystrokes into the second computer, and sends second computer-generated images for display to the first computer. In a second embodiment (FIG. 4), a program (511) executing on a UNIX.RTM.

Abstract: A timing control arrangement that dynamically controls the distribution of timing information in a distributed digital communication system having standard nodes and prioritized master nodes. Reference timing signals to control the system are distributed from the highest priority master node currently operational. Should a higher priority master node than the current master node become operational, the higher priority master node automatically takes control of the timing for the system. Each node is connected by links to at least one other node, and each node receives timing signals and a timing priority number (TPN) from all of the connected node. The TPN defines the number of links over which the timing signals travel to the receiving node from the current master node. Each standard node selects timing signals and TPN from the link having the lowest TPN and transmits the selected TPN (after incrementing the selected TPN by one) and timing signals on all connected outgoing links.

Abstract: Apparatus for automatically polling message service systems to obtain messages for a user of the apparatus. The apparatus is a computer attached to the user's telephone connected to a communication switching system. The computer responds to messages from the communication switching system or to an internal real time clock timing out to poll a number of message service systems to obtain messages for the user. The computer automatically performs logon procedures, message access procedures and message deletion procedures with the various message service systems. If the message service system is audio only, the computer generates audio tones and interprets verbal instruction in order to implement the above procedures.
