Patent number: 6379746Abstract: Methods for temporarily protecting a surface of a glass article by coating the surface are provided. The methods include forming a stable, hydrophobic, removable film on the surface at the end of the glass manufacturing process while the glass is still at an elevated temperature (e.g., above 175° C.). The film reduces chip adhesion to the surface as a result of cutting and grinding. After cutting and grinding, the film is removed allowing the glass to be used in such processes as the manufacture of liquid crystal displays (LCDs).Type: GrantFiled: January 31, 2000Date of Patent: April 30, 2002Assignee: Corning IncorporatedInventors: William Birch, Dana C.

Patent number: 6361020Abstract: A valve for use with an ultra high purity gas comprising a valve body defining a valve chamber having a valve outlet through which gas is discharged and containing a reciprocable sealing member, characterized in that the valve chamber is in fluid communication with a source of the gas and in that the sealing member is reciprocable along an axis substantially parallel to the direction of flow of gas discharged from the valve outlet and into and out of sealing contact with a sealing face located within the valve chamber and circumscribing the inlet end of a valve outlet pipe, the opposite, outlet end of which pipe forms the valve outlet. The valve has a low wetted area and is thus easy to purge, and the valve design both reduces wear and restricts it to a single component which is easily replaced when necessary.Type: GrantFiled: January 12, 2000Date of Patent: March 26, 2002Assignee: The BOC Group plcInventors: David William Birch, Peter Harold Buckley, Kenneth William Cross, Richard A.

Patent number: 5732735Abstract: A pressure reduction valve 2 includes a piston 12, a pressure regulating sub-chamber 50 and a movable means, preferably in the form of a second piston 12', which is activated by a filling nozzle 70 to prevent the flow of fluid between an inlet 8 and the regulating sub-chamber 50 thereby to allow the flow of fluid through the valve between an outlet 10 and an inlet 8. This allows a cylinder to be filled whilst the pressure reduction valve 2 is in situ.Type: GrantFiled: November 8, 1996Date of Patent: March 31, 1998Assignee: The BOC Group plcInventor: David William Birch

Patent number: 4578599Abstract: A flip-flop is provided having a data gate circuit for receiving input data and generating therefrom first and second complementary internal data signals representative of the input data. A master circuit is coupled to the data gate circuit for receiving a clock pulse and for latching the internal data signals during a predetermined portion of the clock pulse. A slave circuit is coupled to the master circuit for storing the internal data signals. A reset circuit supplies a synchronous reset signal to the master circuit for resetting the first and second complementary internal data signals on the occurrence of the next clock pulse.Type: GrantFiled: June 2, 1983Date of Patent: March 25, 1986Assignee: Motorola, Inc.Inventors: William A. Birch, Lillie M. Woodard

Patent number: 4491745Abstract: A master slave flip-flop includes a data gate for receiving the input data and generating therefrom first and second internal data signals, and a master section for latching the internal data signals and for transmitting such signals to a slave section during predetermined portions of a clock signal. In order to render the internal data signals symmetrical with respect to each other and therefore substantially reduce the possibility of transmitting incorrect data to the slave as a result of a race condition in the master section, a Schottky diode is coupled within the data gate to complete a discharge path for one of the internal data lines and thus prevent it from exceeding a predetermined voltage.Type: GrantFiled: August 12, 1982Date of Patent: January 1, 1985Assignee: Motorola, Inc.Inventor: William A. Birch

Patent number: 4413195Abstract: A transistor-transistor-logic circuit includes a discharge circuit coupled between the base of an output transistor and a reference potential. The discharge circuit includes a transistor whose base and collector terminals are resistively coupled to the base of the output transistor and whose collector terminal is resistively coupled to a reference potential. The emitter of the transistor is also coupled to the reference potential. The transistor in the discharge circuit appears as a finite impedance when the output transistor is on and provides a path for discharging the base-emitter charge storage while the output transistor is turned off. The resistor coupled between the collector of the bypass transistor and the reference potential provides a large but finite impedance path for leakage current in said output transistor. This prevents the output transistor from being turned on by the leakage current.Type: GrantFiled: July 10, 1981Date of Patent: November 1, 1983Assignee: Motorola, Inc.Inventor: William A. Birch

Patent number: 4413194Abstract: A transistor-transistor logic circuit includes an output stage comprising a pull-up and pull-down transistor and an input stage for receiving one or more binary logic signals. First and second current drive transistors regulate base drive to the pull-up and pull-down transistors respectively. A first switching transistor turns said first current drive transistor off when the binary signals reach a first logic level. A second switching transistor turns the second current drive transistor on when the binary logic signals reach the first logic level. In this manner, negative reflections at the output of the circuit will not result in the pull-up transistor and its associated current drive transistor being turned off.Type: GrantFiled: July 10, 1981Date of Patent: November 1, 1983Assignee: Motorola, Inc.Inventor: William A. Birch

Patent number: 3949751Abstract: A nasal insufflator for powdered medicaments comprises a tubular body having a longitudinal air passageway. One end of the body has an end suitable for insertion into a nostril, the other end is provided with a squeeze bulb by which a stream of air is driven through the passageway and into the nostril of a user. Wholly within the body and intermediate its ends is a chamber into which can be placed a capsule of powdered medicament. The device is characterised by having a piercing means, eg a needle, which is reciprocable along the axis of the passageway by having its non-operative end mounted upon the inner wall of the bulb. Longitudinal depression of the bulb drives the piercing end of the piercing means through the end walls of a capsule mounted in the chamber. Release of the bulb draws the piercing end back to its non-operative position, thus leaving the capsule pierced and ready to be emptied by transverse depression of the bulb.Type: GrantFiled: August 26, 1974Date of Patent: April 13, 1976Assignee: Fisons LimitedInventors: Leslie William Birch, Desmond Alfred Dean, Harry Howell, deceased
