Title: Diesel particulate trap of perforated tubes having laterally offset cross-wound wraps of inorganic yarn
Inventor: BLOOM RICHARD L
IPC: B01D46/24
Filed: 1993-04-02
Abstract: An efficient, economical, compact diesel particulate trap has a plurality of perforated hollow tubes, on each of which a heat-resistant yarn is helically cross-wound to provide a plurality of layers that function as a filtering element. The yarn, which preferably is a continuous-filament ceramic yarn, has a core from which filaments or fiber segments project outwardly and intermesh with fiber segments of laterally spaced cores to provide traps. The cores of yarn convolutions of at least one layer are laterally offset from the cores of convolutions of an adjacent layer to deflect into tortuous paths gases flowing generally radially through the filtering element.

Title: Hands free noise canceling headset
Inventor: CLAYBAUGH DAVID
IPC: G10K11/16
Filed: 1992-04-30
Abstract: In the area of the active noise cancelation headsets, the noisy environment often encountered in the link with communication systems causes lack of intelligibility on the outward communications path. Consequently another in-wire cancellation channel to enhance the intelligibility is required. This additional processing channel adds to the cost of the headset. The invention uses residual microphones to reproduce the sound that remains in the ear after cancellation so that the controller can make further adjustments through filter and LMS adapter to the anti-noise signal.
Patent CA-2135342-A1 (CA)
Title: Sealing nut and method of making same
Inventor: DEHAITRE LON
IPC: F16B33/00
Filed: 1994-11-08
Abstract: A sealing nut has an annular heat stabilized nylon sealing insert retained within a recess in a metallic nut body by a coined collar on the nut body.   The sealing insert is initially formed symmetrical about a transverse median plane to enable bidirectional assembly into the nut body recess,  and undergoes dynamic preloading when the collar is coined onto the periphery of the insert.  When installed onto a threaded shaft extending from a bearing surface so that the coined collar is torqued against the bearing surface, the sealing insert forms a fluid-tight seal between the threaded shaft and a threaded bore in the bearing surface through which the threaded shaft extends. The nut body and sealing insert facilitate reduced manufacturing costs while enabling re-use without significant loss in sealing properties.

Title: Network-based system enabling image communications
Inventor: MERRITT ANDREW
IPC: H04N21/4786
Filed: 1994-11-17
Abstract: A system is disclosed which enables a multitude of dissimilar end-system devices, appliances, and platforms to interchange image information.  The inventive method utilizes a directory database of end-user profiles, a session manager, a conversion manager, individual conversation processors, a queuing database, and a store-and-forward file-folder database.  The system accommodates pre-subscribed end-users as well as non-subscription users.  The system handles both real-time and store-and-forward communications modes.  The present invention may be practiced as either a one-node or a multi-node distributed architecture, scalable as required, and may be either network-based or premises-based, or a hybrid combination of these.  Communications transport both into and out of the node(s) can range from voiceband telephone on analog circuits to high speed channel or fact-packet protocol communications modes.
Patent CA-2146790-A1 (CA)
Inventor: WILSON MICHAEL
IPC: G07B17/00
Filed: 1995-04-11
Abstract: This invention provides a secure environment to allow the customer to purchase postage for counter resettable postage meters. This invention allows the post office or agent to insure the accuracy and integrity of counter resettable meters by validating the counter resettable meter against a data center funding computer. The procedure would be as follows. The agent interfaces with a central computer where the serial number of the counter resettable postage meter is requested and entered, the contents of the ascending and descending registers are requested and entered. The computer checks as to the validity of the ascending and descending registers. The computer also checks the validity of that particular postage meter with respect to the customers physical location and status (lost or stolen, active). The customer requests and pays the postal agent for the amount of postage to be added to the meter. The computer system processes and verifies the added amount and transmits the approval to a postal agent. Thereupon, the postal agent then takes a key that opens that particular model meter and adjusts the descending register by the approved reset amount. The agent, then securely closes the postage meter with a key for that particular meter.

Title: Improved steam generating apparatus and method of controlling the same
Inventor: ALTMAN MITCHELL
IPC: H05B3/82
Filed: 1995-08-04
Abstract: Improved steam generating apparatus in the form of a thin, compact generally self-contained wall-mountable fixture.  The fixture includes an upright front face section of porcelain or the like for being mounted in the wall of a shower or other enclosed steam room.  The fixture further includes a frame that is fixed to the rear of the face section and supports a closed steam tank or boiler.  A steam line delivers live steam from the boiler into the steam room.  An improved steam head delivers the steam safely and with minimum noise.   The fixture may also include a mirror and be mounted so that the mirror is face height of a standing user.  The mirror is positioned adjacent to the boiler so that heat radiated from the boiler warms the mirror and inhibits it becoming fogged over by the steam in the room.  The fixture also includes an electrical control system that is operable by the user from inside the steam room.  The control system automatically maintains the user-preselected steam room temperature by regulating the power to the boiler so that steam is generated without interruption and after equilibrium is reached there are no noticeable changes in the room temperature.

Abstract: La dimérisation et l'oligomérisation de protéines sont des mécanismes généraux de commandes biologiques contribuant à l'activation de nombreux processus cellulaires. Nous avons mis au point un procédé général de dimérisation ou d'oligomérisation régulée (inductible) de protéines intracellulaires. Comme l'illustre la figure 15, on peut provoquer l'association de l'une ou l'autre de deux protéines cibles en traitant les cellules ou les organismes qui les contiennent avec des ligands synthétiques perméables aux cellules. En résumé, nous avons provoqué: (1) l'aggrégation intracellulaire de la queue cytoplasmique de la chaîne aux états du complexe récepteur (TCR)-CD3 de cellules T, ce qui conduit à la signalisation et à la transcription d'un gène reporteur, (2) l'homodimérisation de la queue cytoplasmique du récepteur de FaS, ce qui implique une apoptose spécifique à la cellule (mort cellulaire programmée) et (3) l'hétérodimérisation d'un domaine de liaison de l'ADN (Gal4) et d'un domaine de transcription-activation (VP16), ce qui provoque la transcription directe d'un gène reporteur.

Title: Mouse driver arrangement for providing advanced scrolling capabilities to a conventional mouse
Inventor: FALCON FERNANDO D
IPC: G06F3/038
Filed: 1995-10-10
Abstract: A mouse driver arrangement combining a first functional block, comprising a scrolling-rate function generator for generating a time-dependent scrolling-ratecontrol signal of pre-defined shape, whose output cycle is a function of the activation status of one or more mouse push-buttons, plus a second functional block, comprising a cursor trail analyzer for detecting a dominant direction in a cursor trail and setting a scrolling direction option accordingly.
