Abstract: A quadruplex receptacle where all four receptacles can be connected in common to a single electrical cable or by severing the connecting links on its line bus it can be divided into two duplex receptacles each fed by a single cable. A feed-through arrangement can be used with either arrangement of the line bus. The neutral bus surrounds the line bus, both supported and electrically insulated from one another by a series of tabs and columns in the cavity within a housing. A ground bus extending into the cavity from a rear cover provides an isolated ground. Mounting apertures in the housing and cover permit mounting to a support surface, to a standard gang gem outlet box, or by means of an adapter plate to a number of mounting devices.

Title: Customer activation system for cellular network
Inventor: HOLMES DAVID WILLIAM JAMES
IPC: H04B3/21
Filed: 1996-11-12
Granted: 2006-12-12
Abstract: A mobile communication terminal device such as a cellular telephone is provided with a preliminary identifier stored in memory. The identifier allows access to a cellular network for verification and provides essentially unique identification by the network, but is insufficient to allow further use of the network. During verification, the identifier is analyzed by a cellular network processor and a determination is made whether the cellular telephone should have restricted access to the network. Upon favorable completion of the identifier analysis, a signal may be transmitted to the cellular telephone that allows the cellular telephone to have less restricted access to the network.

Abstract: A number of distinct parallel digesters are fed with chips from a common steaming vessel. After steaming the chips are slurried and pressurized, and substantially simultaneously the steamed, slurried, and pressurized chips are transferred to at least some of (and typically each of) the distinct parallel digesters. A material stream is split into a number of individually controllable material streams (one for each of the digesters) either at the discharge from the steaming vessel, after slurrying (or at the discharge from a slurrying vessel), or after pressurizing (e.g. in a high pressure transfer device). For example a multi-branch conduit may be connected to the slurry outlet from the high pressure transfer device, the conduit having a branch directly connected to each of the digesters. A distinct return conduit may also be provided from each of the digesters to the high pressure transfer device, each return conduit preferably has a distinct flow control device and/or pump which are individually controlled.

The degree to which the colour location can be affected may be reinforced by a luminophore coating (4). To achieve the operation of the invention, the discharge chamber (3) has at leat one additional electrode (13, 14) which is separated from the discharge by a dielectric layer (3).

Title: An inexpensive single-fiber bidirectional data link
Inventor: NORTE DAVID A
IPC: H04B10/24
Filed: 1997-11-28
Granted: 2001-11-27
Abstract: An optical wavelength-division multiplexed bidirectional data link (FIG. 1) is constructed using a single multi-mode fiber (130). The link comprises the optical fiber with a single-lens optical transceiver (100, 150) at each end of the fiber. Each single-lens optical transceiver comprises a transmitter in the form of a surface-emitting light-emitting diode (LED 101) that emits light at a wavelength of .85µm, and a receiver in the form of a large-scale optical detector (102) and a dielectric optical filter (103) that has a passband at a wavelength of 1.3µm. In the other transceiver, the wavelengths of the transmitter and the receiver are reversed. The transceiver is made as a single integrated-circuit device and is coupled to the fiber by a single-lens optical coupler (110, 160). The optical coupler is a light pipe (112) that consists of the following: a first surface (114) along the length of the light pipe for positioning adjacent to the transceiver, a reflective planar second surface (111) at one end of the light pipe for positioning in front of the transceiver and forming a 45° angle with the first surface, and a convex lens (113) at the other end of the light pipe for optically coupling light into and out of the multimode fiber.

Abstract: A method of biotreating a solid material to remove an undesired compound usi ng a nonstirred surface bioreactor is provided. According to the method, the surface of a plurality of coarse substrates is coated with a solid material to be biotreated to form a plurality of coated coarse substrates. The coarse substrates have a particle size greater than about 0.3 cm and the solid material to be biotreated has a particle size less than about 250 .mu.m. A nonstirred surface reactor is then formed by stacking the plurality of coate d coarse substrates into a heap or placing the plurality of coated substrates into a tank so that the void volume of the reactor is greater than or equal to about 25 %. The reactor is inoculated with a microorganism capable of degrading the undesired compound in the solid material, and the solid materi al is then biotreated in the surface bioreactor until the undesired compound in  the solid material is degraded to a desired concentration. The process is useful for bioremediation of contamined soils, the desulfurization of coal a nd the biooxidation of refractory sulfide ores and concentrates.

Abstract: In an ATM network node, cells of different service classes are stored in respective buffers and counters respectively associated with the buffers are initially loaded with full-count values respectively corresponding to the weight valeus of the service classes. The initial full-count values are updated respectively with the output values of the associated counters. Control circuitry sequentially interrogates the buffers and the counters in a round-robin fashion. If the output value of each interrogated counter is not decremented to a predetermined value, a cell is forwarded from the associated buffer and the counter is decremented by one. At the end of a round robin cycle, all of the counters are reloaded with the initial full-count values or the updated full-count values depending on the number of cells forwarded from each of the buffers.

On the basis of the obtained period, a judgment is made as to whether rotation of the compressor is in an abnormal state.     An electromagnetic clutch between the compressor and a car engine is controlled on the basis of the judgment.  The protecting device is mounted on a housing of the compressor with the rotation sensor so that wiring is executed only in an engine room.  The protecting device includes a state holding device for memorizing the abnormal state of the rotation of the compressor.  The air conditioner can re-start on condition that a conscious operation is performed to reset the state holding device.
