Title: Two piece multiple inshot-type fuel burner structure
Inventor: WILLBANKS SCOTT A
IPC: F23D14/46
Filed: 1997-11-07
Abstract: A multiple inshot-type gas burner structure is formed from a pair of facing, intersecured stamper sheet metal plates. A spaced plurality of parallel,rectangularly cross-sectioned burner bodies are defined by facing triangular indentation pairs in the plates and have, at front outlet end portions thereof, side indentations which serve to mix air and gaseous fuel received at rear end portions of the burner bodies, and to divert a portion of the fuel/air mixture into crossover channels intercommunicating front interior portions of the burner bodies. The crossover channels have central arcuate closed portions that cooperate with progressively sized standoff dimples extending between opposite wall portions ofthe channels to provide an even crossover flame pattern along the outlet slot section of each channel. At the outlet end of each burner are four flame retention tabs which are transverse to the flow axis of the burner body and serve to prevent induced secondary combustion air from causing undesirable main flame liftoff. Originally rectangular inlet end portions of the burner bodies are laterally inwardly deformed to define generally circular sections that receive and firmly hold hexagonal gas supply orifice fittings mounted on a gas supply manifold pipe. Immediately forward of these deformed circular sections a plurality of primary air inlet openings are formed through the burner body walls.

Title: Buck regulator with plural outputs
Inventor: EDWARDS GARY ARTHUR
IPC: H02M3/155
Filed: 1998-01-23
Abstract: A buck regulator provides two outputs via two transformer-coupled inductors eachcoupled to a respective output capacitor and to a respective diode or switch for allowing current to flow in the respective inductor for charging the respective output capacitor during intervals between pulses of a pulsed input supply. One of the inductors is directly coupled and the other of the inductors is coupled via a further capacitor to the pulsed input supply so that current for charging the respective output capacitors flows in both inductors during the pulses. Each inductor can be tapped, and/or the transformer turns of the inductors are equalized, so that no a.c. voltage appears across the further capacitor and the output voltages can be different. The output voltages can also be stacked or of opposite polarities.

Filed: 1998-01-26
Abstract: An EMP-eliminator is to be created which is simultaneously applicable for multiple frequency bands and highest frequencies and at the same time allows transmission of AC/DC supply voltages. For this purpose a casing (20) set in an outer line (10) is provided as well as a line (24) connected in an electrically conductive manner to an inner line of a coaxial line (30). The line (24) is connected in an electrically conductive manner with the equipment casing (20) on its face side via a gas filled overvoltage suppressor (28). The gas eliminator (28) is set into a threaded cover and thus can be exchanged. Between the equipment casing (20) and the line (24) several bushes (25,26) connected electrically to the line are provided. The length of the line (24) corresponds to the .lambda./4 length of the lowest transmitted frequency band.      Several serially connected resonant cavities result which are matched in their length to different midband frequencies. With this kind of serially connected resonant cavities it is easily possible to transmit several frequency bands and thus protect end apparatuses from interference current impulses. The capacitance of the gas filled overvoltage suppressor (28) is decoupled by the line (24) and the bushes (25,26) to such a degree that use up to 18 GHz is possible.

Abstract: A distributed architecture for control of printing presses includes a job-control computer facilitating at least selection of printing jobs, and a separate image-control computer or computers managing operation of the various imaging devices.  The job-control and image-control computers interact over a computer network, which can range from a single LAN to the Internet; typically, the image-control computer is physically associated with the press, while the job-control computer may be proximate or remote.  The job-control computer may contain on-board storage for retaining multiple printing jobs, or the system may instead include a server computer, connected to and accessible over the network, that serves as a central storage facility.  The job-control computer may allow the operator to perform various functions and adjustments relating to final printing quality, and which may affect the job data, printing-press operation, or both.  The job-control computer may also afford the operator control over ink regulation, typically via a separate dedicated computer.  The architecture of the invention is capable of supporting a plurality of printing presses under the common control of one or more job-control computers.  In this way, a single job-control computer may interact with and direct the operation of remotely located printing presses, each of which is served by a separate image-control computer.

Title: Writing bragg reflection gratings in optical waveguides
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G03F7/20
Filed: 1998-09-21
Abstract: Instead of a single beam, two coherent beams of light are used to illuminate a phase grating in spatially separated zones for writing a Bragg reflection grating in an underlying optical (fibre) waveguide. Close proximity between phase grating and waveguide is not required. This facilitates the use of masking so that only two different diffracted orders contribute to the fringe pattern that generates the Bragg grating, thereby improving fringe contrast and reducing the deleterious spectral effects upon the reflectivity of the Bragg reflector occasioned by the presence of stitch errors in the phase grating.
