A process for the bleaching of cellulosic fibres comprising the steps of (a) providing a water supply; (b) adding hydrogen peroxide to the stabilised water supply to form a hydrogen peroxide solution; (c) adjusting the pH of the hydrogen peroxide solution by adding alkali; mixing the pH adjusted solution resulting from step (c) to allow complete formation of perhydroxyl ion; (e) adding a carboxylic acid anhydride compound to the solution resulting from step (d); (f) mixing the solution resulting from step (e) to allow complete formation of percarboxylic acid to give a dilute solution of percarboxylic acid; and (g) contacting the solution with a suspension of cellulosic fibres.

A urinary apparatus includes a catheter system for pressurizing either a bladder cavity or a urethral canal within a female urinary system and an endoscope device for observing a urethral sphincter muscle within the female urinary system for assessing the sling tension of an implant support adapted to restore female urinary continence. The catheter system includes a obturator occlusion member for plugging the urethral canal during the performance of a sling tensioning procedure.

A reduced size multiplexer and, in particular, a reduced size SONET multiplexer module is provided for use in a reduced size enclosure. The SONET multiplexer module has electrical and optical connectors on its faceplate to provide ease in access without having to remove the SONET multiplexer from the enclosure. The SONET multiplexer circuit is configured in a standard Type 400 mechanics circuit board arrangement. The SONET multiplexer module therefore can be inserted into an enclosure in a direction opposite to that in which the coaxial connector projects from the face plate, so that the coaxial connector remains freely accessible outside of the enclosure when the SONET multiplexer module is fully loaded into the enclosure. Coaxial cables and optical fibers can thus be easily coupled to the coaxial and optical connectors, respectively, when the SONET multiplexer circuit is fully loaded into the enclosure.

A device and method for dispensing and measuring a plurality of strands from a single spool of stranded material is disclosed. The device is comprised of a mobile portion on which a plurality of pulleys is mounted. The mobile portion includes a frame mounted on an axle to which tires are attached so that the mobile portion may be wheeled about readily. A stationary portion includes a plurality of pulleys and a supply spool of wire. Stranded material from the supply spool is routed back and forth between the mobile portion and the stationary portion, over the pulleys attached to each, until the number of strands between the mobile portion and the stationary portion corresponds with the desired number. Next the mobile portion is displaced away from the stationary portion a distance equal to the length of strands desired. A distance measurement device is mounted on the mobile portion to aid the user in ascertaining the distance that the mobile portion has moved, thereby indicating the wire length. Another embodiment of the invention includes open-faced pulleys that facilitate more rapid routing of the wires over the pulleys during use thereof.

A method of playing a multi-line poker game of cards on a computer-based video gaming device is disclosed. The poker game has a game hand line and a plurality of bonus lines that are combined to create a game array. The game array itself has a plurality of paylines used in determining winnings for the play of the game. The method of playing the multi-line poker comprises determining a set of game parameters from a set of input signals from a player. Next a plurality of cards are randomly dealt from a deck of cards to fill the game hand line. The player selects cards from the within the game hand that are to be held and the cards that are to be discarded. Cards from the deck of cards are randomly dealt to replace all of the cards discarded from within the game hand. Each card now within the game hand is duplicated and randomly placed within the plurality of bonus lines until all of the locations within the game array are filled with cards. Winning combinations of poker hands are determined for the paylines contained in the game array. An award amount is determined for all winning combinations found within paylines based upon the winning combination, the identity of the payline, and the amount of any wager placed on the payline containing the winning combination.

A cable lasher is provided for securing a telephone or transmission cable to a support strand strung in the air between adjacent utility poles to prevent sagging of the transmission cable. As the cable lasher traverses a span of the support strand, the lasher pays out a line of lashing wire that is helically wrapped around the cable and the strand to bind them together. A series of tensioning rollers maintains constant tension in the lashing wire at all times to ensure a tight uniform wind. A gearbox translates linear motion of the lasher along the guide wire into rotational motion of a drum portion of the lasher. The rotation of the drum causes the wrapping of the lashing wire about the cable and the strand. A one-way clutch allows the drum to rotate only in one direction when the clutch is engaged in order to prevent any slacking in the wound lashing wire.

A heat transfer arrangement for one or more heat-generating components (18a) on a printed-circuit board (16) includes a heat transfer plate (316) defining an aperture (416) registered with the components. A "vertically" movable heatsink adapter (410) is adjusted to juxtapose its "lower" surface with the "upper" surface of the components to be heat-sunk. A heat-transfer pad (318) may be used between the heatsink adapter (410) and the component (18a). In various embodiments, the heatsink adapter takes the form of circular (410) or rectangular (410R) plugs, a draw-tube (808) arrangement, or a bellows (1010).
摘要:
The present invention comprises a voltage controlled oscillator (VCO) circuit having high power supply noise rejection. The VCO circuit includes a VCO input for receiving a control voltage. A level shifter circuit is coupled to the VCO input. A first and second VCO cell are coupled to the level shifter circuit and are coupled to each other. The VCO circuit also includes a VCO output for transmitting a VCO output signal. A first source follower transistor is coupled to the first VCO cell to transmit a first voltage from the power supply to the first VCO cell. A second source follower transistor is coupled to the second VCO cell to transmit a second voltage from the power supply to the second VCO cell. A first and second load transistor are included in each VCO cell. They are directly coupled to receive the control voltage such that the VCO output signal is less sensitive to noise on the power supply and the VCO output signal remains stable. Additionally, the level shifter is coupled to control the first source follower transistor and the second source follower transistor such that the first voltage and the second voltage are insensitive to noise on the power supply.
