Abstract: A data structure, such as a telecommunications connection map, comprises at least one list of data elements which are stored in a predetermined sequence of locations of a memory device (52). The structure is updated by moving a portion of the list through the sequence of memory locations so as to insert a new element into, or delete or change an existing element at, a particular position in the structure while maintaining the order of the list. Elements of the structure are read in the sequence in which they are stored and the structure is updated during the accessing of the structure by moving elements through the sequence of memory locations. A particular application of this invention is in maintaining a connection map for a telecommunications switch, the map storing connection instructions defining into which ATM cell payload received narrowband call data is assembled.

Title: Amidases, nucleic acids encoding them and methods for making and using them
Inventor: REID JOHN C
IPC: C12P21/08
Filed: 1997-06-17
Abstract: A purified thermostable enzyme is derived from the archael bacterium Thermococcus GU5L5. The enzyme has a molecular weight of about 68.5 kilodaltons and has cellulase activity. The enzyme can be produced from native or recombinant host cells and can be used for the removal of arginine, phenylalanine, or methionine amino acids from the N-terminal end of peptides in peptide or peptidomimetic synthesis. The enzyme is selective for the L, or "natural" enantiomer of the amino acid derivatives and is therefore useful for the production of optically active compounds. These reactions can be performed in the presence of the chemically more reactive ester functionality, a step which is very difficult to achieve with nonenzymatic methods.

Title: Transparent functional membrane containing functional ultrafine particles, transparent functional film, and process for producing the same
Inventor: SUZUKI HIROKO
IPC: G02B1/18
Filed: 1994-12-02
Abstract: The present invention provides a transparent functional film comprising a transparent plastic substrate film and a hard coat layer provided thereon, wherein functional ultrafine particles are present in a highly localized form, thereby enabling the functional ultrafine particles to effectively exhibit their function and, at the same time, the hard coat layer to have a good adhesion to the functional ultrafine particle layer; and also an antireflection film and processes for producing the transparent functional film and the antireflection film.     A functional ultrafine particle layer 2 is formed on a release film 1.  Separately, a resin composition for a hard coat layer is coated on a transparent plastic substrate film 3.  The coated release film is laminated by press bonding to the coated transparent plastic substrate film so that the functional ultrafine particle layer 2 faces the resin composition coating, thereby causing part of the functional ultrafine particles 5 to be embedded in the resin composition coating for a hard coat layer.  The resultant laminate is cured, and the release film 1 is then peeled off.  In the resultant transparent functional film, the functional ultrafine particle layer 2 is partly embedded in and fixed to the hard coat layer 4, and the functional ultrafine particles 5 are localized in the hard coat layer 4 on its surface side.

Abstract: A fluid separation system is provided for separating wellbore fluids into production fluids and non-production fluids. The system includes a separator adapted for transmitting mechanical power between a drive motor and at least one pump.  The separator includes one or more separation units, such as hydrocyclone separators. A drive train traversing the separator is interfaced with drive elements, such as a submergible electric motor, and driven elements such as an injection or production pump. Wellbore fluids are channeled through the separator in either a push-through or pull-through manner. Production fluids are then transferred from the separator to the production pump for removal from the well. Non-production fluids are transmitted from the separator either to the injection pump for reinjection into a subterranean discharge zone, or directly into the discharge zone from the separator. The drive train elements traversing the separator are supported by antifriction bearings in interface plates on either end of the separator. The ability to transmit mechanical power through the separator facilitates assembly of pumping system components in various configurations as well as piping fluid communication paths between the pumping system components.

Patent CA-2279866-A1 (CA)
Inventor: JAEGER ERICH
IPC: B26D1/28
Filed: 1998-01-28
Abstract: The invention concerns a method of cutting up or trimming flat objects along cutting lines running parallel to a delivery direction (F), said flat objects being continuously delivered substantially parallel to their main surfaces in the delivery direction (F). The objects are guided between a first and a second cutting edge (SK1 and SK2) and cut by a relative movement of the two cutting edges. The first cutting edge (SK1) is thus disposed in stationary manner, for example, in a plane in which the objects rest and the second cutting edge (SK2) is guided past the first cutting edge for a cutting process such that at least the cutting point on the second cutting edge (SK2) has, in the delivery direction, a speed component which is equal to the delivery speed and a speed component perpendicular to the resting plane. This is preferably brought about in a pivot movement of the second cutting edge (SK2) about a pivot axis (M) which is disposed above the resting surface, the distance (.gamma.) and the pivot speed (.omega.), in order to satisfy the above condition, being adapted accordingly to each other and to the delivery speed. Advantageously, a plurality of second cutting edges (SK2) are disposed in a star-shaped manner in a plane perpendicular to the pivot axis (M) and the arrangement is rotated by the second cutting edges (SK2) at a constant speed (.omega.) about the pivot axis (M).

Title: Method and system for visualizing software execution
Inventor: WARE COLIN
IPC: G06F11/36
Filed: 1999-08-31
Abstract: Rapidly advancing hardware technology has been fueling a steady increase in software complexity. Not only are programs becoming larger but more complex and intricate interdependencies are being formed between software objects. Given that multiple processes or threads can act within an application, software understanding and debugging can become extremely difficult. This thesis explores the use of 3D  visualization to simulate the execution of a program within the context of its structure, for the purposes of training and debugging. In order. to intuitively visualize software execution in 3D, a 3D model of executing software has been implemented. This model uses NestedVision3D, a software structure visualization tool, to display the source code's static structure. A novel concept called the snake has been developed to superimpose software execution onto NestedVision3D graphs. The software execution is time sequenced against a running clock;  therefore all three dimensions can be used for simulation, none having to represent time.  Animations are derived from execution traces collected from various sources.
