Title: Electrostatic target recalculation in a xerographic imaging apparatus
Inventor: MACDONALD DANIEL W
IPC: G03G15/01
Filed: 1992-08-25
Granted: 1999-05-04
Abstract: Recalculation of electrostatic target values in a tri-level imaging apparatus are utilized to extend the useful life of the photoreceptor (P/R). The increase in residual voltage due to P/R aging which would normally necessitate P/R disposal is obviated by resetting the target voltage for the full ROS exposure when it reaches its exposure limit with current P/R conditions. All contrast voltage targets are then recalculated based on this new target. The new targets are calculated based on current capability of the overall system and the latitude is based on voltage instead of exposure.

A pusher is moveable longitudinally along the track over a range of operative positions, between a retracted position and an advanced position, and laterally between the retracted position and an inoperative position. The pusher is biased longitudinally so as to push the strip along the track, toward the advanced position, when the pusher is in the range of operative positions. The pusher is biased laterally toward the inoperative position, in which it can be releasably latched. A button is arranged to be manually depressed to release the pusher.

Title: Call routing in mobile telephone systems
Inventor: SAWYER FRANCOIS
IPC: H04W8/06
Filed: 1992-10-22
Granted: 2003-04-22
Abstract: A method and apparatus for providing continuous and accurate location information pertaining to a mobile telephone subscriber wherein a temporary location is utilized. Upon entry to a visited system the mobile subscriber either transmits a registration access or a call access. If the mobile subscriber sends a registration access, the visited system acknowledges the registration, records the mobile subscriber's presence and signals the mobile subscriber's home system of the mobile' s presence. Receipt of the mobile's location from the visited system causes the mobile subscriber's home system to update its location data for that particular mobile. If the mobile subscriber initiates a call access from within the visited system without registering within the visited system, the visited system allocates a record for the mobile indicating within the record that it has not received a registration from the mobile and transmits to the home system a temporary location signal. The home system, upon receipt of the temporary location stores the location without deleting the existing location data for the mobile subscriber. The temporary location data is deleted upon the conclusion of the mobile subscriber's call from within the visited system. The temporary location data is used by the mobile subscriber' s home system to effectuate the routing of calls for the mobile subscriber.

Title: Computer system with automatic adapter card setup
Inventor: THOMPSON STEPHEN PATRICK
IPC: G06F13/14
Filed: 1992-11-30
Granted: 1996-12-03
Abstract: A  computer  adapter  card  includes  a  plurality  of  setup registers    for   receiving    setup   parameters   during initialization of the computer system.   Each of the setup registers of an adapter card is accessed at the same address as the corresponding setup register of all other adapter cards in the system.   The adapter card is designed to be connected to a computer bus that does not include individual setup lines for each of the adapter cards in the system.  To select  an  individual  adapter  card,  each  adapter  card includes a register for storing a programmable adapter card number,  a  plurality  of  switches  for  selecting  a  switch selectable  adapter  card  number,  and  a  comparator  for comparing the programmable adapter card number to the switch selectable adapter card number.   When an adapter card is initially installed in the computer system,  the user sets the switches to correspond to the number of the adapter card slot into which the card is inserted.  Thus, the switches of each adapter card in the system are set to a unique switch seleted number.  When the comparator detects a match between the programmable and switch selectable adapter card numbers, and when the adapter card is placed in the setup mode, the setup registers of the selected adapter card are enabled, such that the computer system can write setup parameters to, and read setup parameters from the setup registers of the selected adapter card.

A generally J-shaped portion of the edge-covering leg defines a channel opening toward the lip, grasping an inner portion of the strip releasably, and having an edge spaced inwardly from the lip. An outer portion of the strip extends beyond the lip and performs such masking function.

Abstract: On décrit un procédé pour réduire la tendance à l'agglomération des hydrates au sein d'un fluide comprenant au moins de l'eau et des hydrocarbures, susceptibles de former des hydrates, dans des conditions où ces hydrates peuvent se former, caractérisé en ce qu'on incorpore audit fluide un polymère ou copolymère hydrosoluble à base d'oxyde d'alkylène contenant au moins une séquence -(OR)-n dans laquelle R représente un groupement hydrocarboné de 2 ou 3 atomes de carbone et n représente le degré moyen de polymérisation de ladite séquence, au moins une des séquences -(OR)-n étant une séquence polyoxyde d'éthylène, en association avec un inhibiteur thermodynamique de formation des hydrates, par exemple un alcool ou un glycol. Ce procédé est particulièrement adapté au cas où le fluide à traiter contient une forte proportion d'eau, par exemple plus de 30% en masse. La présence de sels dans l'eau peut dispenser au moins partiellement de l'addition d'alcools ou de glycols. Les polymères et copolymères mis en jeu sont plus particulièrement des polyéthylèneglycols, des copolymères séquencés d'oxyde d'éthylène et d'oxyde de propylène, par exemple obtenus par condensation d'oxyde d'éthylène sur un polypropylèneglycol, ou par condensation d'oxyde de propylène sur de l'éthylène diamine suivie de la condensationd'oxyde d'éthylène.

Title: Ophthalmic lens inspection system and method
Inventor: EDWARDS RUSSELL J
IPC: G01M11/00
Filed: 1993-12-17
Granted: 2005-04-05
Abstract: A lens inspection method and apparatus is disclosed comprising a pallet having wells for receiving one or more lens containers at the receiving point. A conveyor achieves uniformity of pallet motion needed in the direction of pallet travel and stability when transporting the lens in the orthogonal, non-translating directions by use of one or more guide rails and a mechanical bias means. Pallet wells for receiving the containers comprise holes that pass through the pallet. These holes along with a side driven transport system make possible an arrangement of a lamp and camera on opposite sides of the lens for capturing an image of a lens. A computer implemented algorithm processes the digitized image according to rules set forth in a program to determine the acceptability of the lenses. A lens disposition mechanism connected to the computer uses a signal generated by the computer and indicates lens acceptability to disposition the lens by physically separating a container with an acceptable lens from an unacceptable lens. After disposition of containers, the pallet is returned by conveyor to the lens receiving point.

Abstract: A method of obtaining glass materials from ash-slag waste wherein the waste is heated to a melting point temperature and melted in a reducing medium. The obtained melt is cooled by a thermal shock to form a foamed glass material. Prior to heating the charge, the carbon content therein is brought to 3.0 - 8.0 wt %, and the foamed glass material is foamed under a flow of a gaseous medium resulting from decomposition of carbides formed in the melt as a result of carbon content adjustment. Carbon addition also reduces iron oxide present in the waste, this reduction facilitating iron separation from the foamed material.

Granted: 1999-01-26
Abstract: A screw compressor employs a piston unloader which is disposed in a bore remote from the compressor's working chamber. Flow communication between the bore and working chamber is through a series of n on-overlapping unloader ports. The unloader piston has a notched end face which effectively causes the unloader ports to ove rlap in operation. Precise and continuous capacity control of the compressor over a predetermined portion of its operating range is thereby achieved while internal high to low side gas leakage within the compressor and the clearance volume of the unloa der ports is minimized. Compressor efficiency is thereby increased.
