Title: Asynchronous transfer mode switch architecture
Inventor: CYR GREGORY JOHN
IPC: H04L12/56
Filed: 1995-03-28
Granted: 1999-09-28
Abstract: A high capacity packet switch is implemented using an expansion module that divides an incoming packet cell into a plurality of segments and supplies the segments, based on their sequential order, to respective ones of a plurality of concentrator units contained in the expansion module. Each concentrator unit includes a plurality of concentrator logic units and one of those logic units accepts a segment for storage based on routing information contained in the packet cell. The stored segments forming a packet cell are thereafter unloaded and recombined in proper sequence for routing to a packet switch module, which then forwards the packet cell toward its destination.

Abstract: Novel mammalian phospholipase (PLA2) nucleotide sequences and low molecular weight (about 14 KD) amino acid sequences encoded thereby are disclosed. More particularly, a cloned human HPLA2 cDNA  expressing HPLA2 -10 and its cloned rat RPLA2 cDNA counterpart, expressing RPLA2 -10, which are characterized as PLA2 Type IV, are disclosed. A second type of PLA2 cDNA, characterized as PLA2 Type III and exemplified by a rat PLA2 cDNA encoding RPLA2 -8 and a partial human PLA2 nucleotide sequence encoding HPLA2 -8, is disclosed. Expression of the cDNAs encode the two new types of PLA2 enzymes which have phospholipase activity. The novel PLA2s do not include disulfide bridges between cysteine amino acids 11 and 77 or elapid loops. However, the novel PLA2s may include amino acid COOH-terminal extensions which can vary in length. Seventeen of the eighteen absolutely conserved amino acids in all active 14 KD PLA2s are believed to be conserved in RPLA2 -8 and HPLA2 -8, whereas all eighteen are believed to be conserved in RPLA2 -10 and HPLA2 -10. Because me encoded sequences of RPLA2 -8 and HPLA2 -8 include only 16 cysteine amino acids, they have been designated as Type III. RPLA2 -10 and HPLA2 -10 are designated as Type IV since their encoded sequences include only 12 cysteine amino acids.

Granted: 2000-04-18
Abstract: An apparatus is disclosed for mounting a chamber door (12) between open and closed positions relative to the opening of a sterilizer or autoclave chamber (10). The apparatus is adapted to be used in either motorized or non-motorized embodiments. The weight of the chamber door (12) is offset by a counterweight (16) and suspended using a cable (14) and pulley (18) system. In the non-motorized embodiment, the door/counterweight system is held in place by a securement, which, when disengaged, permits free motion of the door (12). In the motorized embodiment, a second cable (40) and pulley system is used to connect the door (12) and counterweight (16). The cable (40) from this second system is looped around a sheave (42) which is adapted to provide a predetermined frictional force. The sheave (42) is then connected to and rotated by a motor (44), and upon activation of the motor (44), the rotating sheave (42) displaces the cable (40), which respectively raises or lowers the door (12) and counterweight (16). In the event that the door (12) is obstructed during operation or forced open, the cable will slip harmlessly along the sheave (42), and will neither injure the operator nor induce damaging torques in the motor (44).

Abstract: Hydrocleaning apparatus for pipelines and the like includes a frame capable of advancing lengthwise of the pipeline, such frame carrying a plurality of liquid jetting modules which, in use, are disposed in an array around the pipeline surface to enable cleaning of the entire surface to be effected.  The frame can be opened up to allow the apparatus to be fitted to or removed from a continuous pipeline.  The frame arrangement and module mounting system are designed to provide good cleaning efficiency and proper orientation of the various modules in spite of pipeline irregularities including out-of-round conditions, uneven coating thicknesses and wrinkles.  A pivoting module mount helps to maintain cleaning efficiency in the case where thick coatings are being removed.  The frame drive wheels are disposed forwardly of the modules to avoid contamination of the cleaned surfaces by deposits that may build up on the wheels.  A shroud system connected to the modules prevents substantial escape of contaminating liquids and debris into the environment.

Abstract: Extruded pellets comprising a majority of activated carbon particles and an organic binder provide improved performance when processed through tumbling equipment while the pellets are in their "green" state, i.e., pellets which are fresh off the extruder and contain activated carbon, binder, and water and have not been subjected to any thermal processing (drying). The tumbling action both smoothes the pellets (by closing any cracks and greatly improving appearance) and increases the density of the packed bed, e.g., by increasing particle density and reducing voids between the pellets. Improved performance results from an ability to increase the weight of carbon pellets which can be packed into a fixed volume and thereby increase the volumetric working capacity of the bed for adsorbing/desorbing vapors. Another benefit is to greatly reduce the levels of dust associated with the carbon, both the initial dust and the dust attrition.
