Abstract: A reverse address resolution protocol for use in a communication network which allows resolution logic to provide a higher level protocol information (such as an IP address) to a source of a request (127) for such information (122), independent of the physical network address of such source. The protocol is used in a processor having a plurality of parts, at least one of such ports connected by a point-to-point channel to a remote network device. Reverse address resolution protocol is responsive (129) to a resolution request from the remote network device across the point-to-point channel to supply the higher level protocol information based upon the port through which the resolution request is received (125), rather than the physical network address of the requesting device. Thus, a remote device may be coupled to a network, and connected to a central management site across a point-to-point communication link, in a "plug and play" mode. The person connecting the device to the remote network does not need to determine the physical network address of the device or configure the device with a higher level address protocol.

Abstract: A Z-folded barrier cuff is provided to allow both sufficient lateral spacing of the barrier cuffs for the genitals in the front and for BM containment in the back as well as sufficient cuff height in the crotch area for good fit into the leg crease and good containment of body exudates. The barrier cuff is Z-folded by folding a first portion back upon itself such that a first segment and a second segment is formed. A second portion is folded laterally inwardly back upon itself such that a third segment is formed. Thus, the Z-folded barrier cuffs are properly laterally spaced in the crotch area and near the end edges while providing sufficient height to properly contain body exudates.

Abstract: Systèmes de décharges utilisés pour l'analyse chimique y compris pour l'identification et la quantification d'impuretés gazeuses et se composant d'une paire d'électrodes qui créent entre elles une étincelle de préférence pulsée. Lorsqu'un gaz inerte passe entre les électrodes, l'étincelle y donne naissance à des photons énergétiques qui sont émis et utilisés ainsi que décrits. Dans d'autres variantes, d'autre particules énergétiques créées dans l'espace séparant les électrodes restituent ensuite leur énergie. L'émission de photons ou la perte d'énergie contribuent à l'identification et à la mesure de pics fournis par un chromatographe courant. Le gaz inerte préféré est de l'hélium avec ou sans traces de gaz rares inertes.

Abstract: A balloon (10) for use in compressing cancellous bone and marrow (also known as medullary bone and trabecular bone) against the inner cortex of bones whether the bones are fractured or not. The balloon comprises an inflatable, non-expandable balloon body (12, 14) for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon is prevented from applying excessive pressure to the outer cortical bone. The wail or walls of the balloon are such that proper inflation of the balloon body is achieved to provide for optimun compression of all of the bone marrow. The balloon is folded so that it can be easily inserted into a bone. The balloon can he made to have a suction catheter (16). The main purpose of the balloon is the forming or enlarging of a cavity or passage in a bone, especially in, but not limited to, vertebral bodies.

Title: Thermal apparatus and process for removing contaminants from oil
Inventor: TACIUK WILLIAM
IPC: B01J19/28
Filed: 1996-09-27
Granted: 2001-10-30
Abstract: Used oil is treated in a reactor to remove contaminants. The reactor comprises a rotating vessel forming an internal reaction chamber. The vessel is housed within a heating chamber. The inside of the vessel is indirectly heated by conduction through the vessel walls. The reaction chamber contains a permanently resident charge of non-ablating, granular coarse solids. Within the reaction chamber, the oil is vaporized and pyrolyzed, producing a hydrocarbon vapour. Coke is formed as a byproduct. Contaminants, such as metals and halides become associated with the coke. The coarse solids scour and comminute the coke to form fine solids. The fine solids are separated within the reaction chamber from the coarse solids and are removed from the vessel through a pipe located at the axis of the vessel. The hydrocarbon vapours are also removed from the vessel through the axial pipe, as a separate stream. Residual fine solids are separated in a cyclone from the vapour stream. The cleaned vapour stream is then condensed to produce a substantially contaminant free product oil. The contaminant-rich solids are collected for disposal.

Abstract: A method of pulse width modulation using a spatial light modulator (40) with a finite transition time. The method uses m bits per sample to digitize the incoming data, but apportions the LSB times for pulse width modulation based upon m-1 bits. The current video frame displays all of the bits for each sample, except for the LSBs for each sample. The next video frame displays all of the bits for each sample, adding one more LSB for dividing up the frame time. The first frame could use either the additional LSB time and display no data, or it could use only that number of LSB times it needs. In the latter, the system will have to adjust to different partitions of the frame time for alternating frames. The system includes a spatial light modulator (40), a memory (42), a formatter (48), a sequence controller (44) and a toggle circuit (46), to perform this method.
