Title: Improved brush filaments
IPC: A46D1/00
Filed: 1993-11-03
Abstract: The invention provides novel, improved wear indicating brush filaments and novel, improved coextrusion process for their manufacture. Essentially, the filaments of the present invention are coextruded filaments which include a longitudinal surface (22) providing a boundary about the cross-sectional area (24) of the filament and the longitudinal surface (22) and/or the cross-sectional area (24) presents a two-colored region (26, 28) adapted to provide a visual signal indicative of wear in response to filament use.  The filaments can be natural or synthetic materials. In filaments of the present invention, the colored region (26, 28) provides an initial color or color intensity viewable to the user. As wear is produced by continuing use of the filaments, the intensity of the colored region (26, 28) changes to a point which signals the user that the filament no longer provides the requisite performance characteristics for effectively performing its assigned function.

Title: Channel module for a fiber optic switch with bit sliced memory architecture for data frame storage
Inventor: BENNETT DWAYNE R
IPC: H04B10/291
Filed: 1995-07-13
Abstract: A channel module  (34)  has an interchangeable port intelligence system (71a, 71b, 71c) at a front end which is connected to a memory interface system (72) at a back end. Each port intelligence system (71a, 71b, 71c) provides one or more ports (33) for connection to fiber optic channels (32) and, the various port intelligence systems (71a, 71b, 71c) are distinguishable by a particular bit rate in which each supports.   Data from the port intelligence system (71a, 71b, 71c) is bit sliced and forwarded to the memory interface system (72).   In the system (72), the data is stored in receive memory (84) in a distributed manner over a plurality of receive memory components (131).  The bit slicing  simplifies  the  input/output  interface  to  the receive memory  (84)  and enables storage of data with a common format, regardless of the rate at which the data was received from the channel (32).  When data is read from the receive memory (84), each of the receive memory components (131) contributes bits in order to reconstruct the data.

Title: Ballast containing protection circuit for detecting rectification of arc discharge lamp
Inventor: SUN YIYOUNG
IPC: H05B41/24
Filed: 1995-08-01
Abstract: A ballast includes an inverter for providing an AC voltage to a discharge lamp. As the lamp approaches end-of-life, a DC voltage component develops across the lamp. The ballast includes circuitry for monitoring the condition of each of the cathodes by measuring this DC voltage component. After a predetermined increase in this DC voltage component, the inverter is disabled in order to prevent excessive heating of the cathodes.      The inverter is also disabled as a result of a resonant or near resonant mode condition of a tank circuit caused by an open circuit condition or a leaking lamp.

Title: Methods and apparatus for providing suppressed ringing access
Inventor: COURVILLE BERNARD
IPC: H04M11/00
Filed: 1995-08-23
Abstract: In methods and apparatus for providing suppressed ringing access to a subscriber line, a connection request is sent from a server to a telecommunications switch and the switch performs a connection routine in response to the connection request to connect the server to the subscriber line.  The connection routine is adapted to avoid audible ringing of a telephone set connected to the subscriber line. The connection request comprises a signal indicating a subscriber line to which the server is to be connected and a signal indicating that suppressed ringing access to that subscriber line is desired.  The methods and apparatus avoid the need for especially provisioned trunks between the server and the terminating switches by including in the connection request a signal indicating that suppressed ringing is desired and by making the telecommunications switch responsive to that signal.

IPC: H05K3/30
Filed: 1995-09-19
Abstract: A fuse holder assembly (100) has a pair of fuse clips (23) which provide electrical connection between a fuse (22) and a circuit in a printed circuit board (15). The fuse holder assembly (100) securely holds a fuse (22) adjacent to an edge of the printed circuit board and in spaced relation to the printed circuit  board (15) for easy access to the fuse and for maximizing the area on the printed circuit board available for circuit components or edge connector contacts.  Each fuse clip (23) has a mounting base (25) for mounting to the printed circuit board and for providing electrical connection with the circuit on the printed circuit board, and a retention clip (33) attached to the mounting base.  A support (55,58) supports the retention clip and provides access (53,70) to the retention clip for installation and removal of a fuse within the retention clip.  The support (55,58) limits the movement of the retention clip with respect to the printed circuit board, while allowing resilient deformation of the clip for receiving and releasing a fuse.

Patent CA-2159790-A1 (CA)
Title: Control of Prime Mover in HVAC Distribution System
Inventor: AHMED OSMAN
IPC: F24F11/04
Filed: 1995-10-03
Abstract: A controller controls a prime mover (source component) in a heating, ventilation and air-conditioning (HVAC) distribution system. The controller determines a static pressure setpoint for the source component by first determining the pressure loss of each branch throughout the system. The controller then determines the pressure loss contributed by local components located within each branch of the system. The maximum of the branch pressure losses and the maximum of the component pressure losses are summed to provide the static pressure setpoint for the source component. The method provides improved control of the prime mover independent of the configuration of the system, which allows for easy and cost-effective implementation of the control method.

Title: Rotary anode type x-ray tube and method of manufacturing the same
Inventor: ONO KATSUHIRO
IPC: H01J35/10
Filed: 1995-10-12
Abstract: A rotary anode type X-ray tube comprises a thin gas passageway extending from a lubricant chamber formed along the axis of a stationary structure and open at a fine gap G effective for preventing a lubricant leakage.  In manufacturing the tube, a liquid metal lubricant is supplied to the lubricant chamber and to a slide bearing section, followed by assembling the tube and, then, sealing the assembled tube in a vacuum vessel.  In the subsequent exhausting step, an open end of the gas passageway is allowed to face upward.  The particular exhausting operation permits completely releasing to the outside the gas impregnated in the bearing-constituting members and the liquid metal lubricant, making it possible to maintain a stable bearing function.

Patent CA-2176700-A1 (CA)
Inventor: ROE DONALD CARROLL
IPC: A61F13/15
Filed: 1994-11-18
Abstract: Absorbent articles such as disposable incontinent briefs, diaper holders, training pants feminine hygiene garments, and the like, having ex-tensible side panel features that improve the dynamic fit of the diaper around the legs and waist of the wearer. Such absorbent articles comprise a con-tainment assembly comprising a liquid pervious top-sheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the back-sheet; and extensible side panels, each comprising a waist panel and a thigh panel disposed along each longitudinal edge of the containment assembly in the first waist region. The waist panel and the thigh panel are operatively associated so that the waist panel has a primary direction of extensibility in one direction and the thigh panel has a primary direction of exten-sibility in a different direction. This forms a multi-directional extensible side panel wherein the waist panel provides tension around the wearer's waist to maintain fit about the waist and to hold the diaper on the wearer, and the thigh panel expands and con-tracts to maintain a dynamic fit around the leg of the wearer. Thus, the waist and thigh panels reduce the negative effects of the dynamic forces on the ab-sorbent article, such as sagging and gapping that can cause leakage, while increasing freedom of motion and wearer comfort.
