  • Patent number: 4817013
    Abstract: An improved gas analyzer system (FIG. 1) and method of use for detecting and displaying the constituent gases of a respiratory gas stream, the system comprising an optical bench (109) through which a respiratory gas flows and in which measurements of the gas are taken; analog input circuits (122) for receiving signals output from the optical bench (109); analog processing circuits (124) for processing signals output from the analog input circuits (122); display processing circuits (128) for processing the signals output from the analog processing circuits (124) and other system circuitry; pixel logic circuits/analog outputs (130) for processing signals output from the display processing circuitry (128) and providing analog output ports; a five button panel (148), an alarm-knob board (144), and a speaker driver (152) for operator interface and activation of audible and visual alarms; a CRT driver for driving the CRT; and a power supply (158) for powering the system.

  • Patent number: 4328971
    Abstract: Conventional dartboard wiring grids and their attachment structures obscure a significant proportion of the target areas. The invention aims to provide an improved definition of target areas by using fine high tensile wires for the grid. The grid is formed in such a manner that the fine wires are not easily bent on impact but can be easily replaced should they become bent. The grid (11) has straight high tensile radial wires (17) running from an inner ring (20) to an outer ring, endless high tensile wires (18,19) defining doubles and trebles and a plurality of pegs (18c, 18d, 19c 19d) projecting in concentric circles from the board, the endless wires being held in tension around the circles of pegs. The endless wires preferably overlie the radial wires and are held clear of the dartboard surface.

  • Patent number: 4262910
    Abstract: The invention provides a dartboard having a wire grid defining the target areas which enables finer wire than conventional to be used. The grid consists of straight high tensile radial wires and arcuate high tensile wires with bent ends pushed into the dartboard adjacent the radial wires to define the target areas within the sectors defined by the radial wires. Each ring of the target areas can conveniently be made up of a series of separate arcuate wires with bent ends and each radial wire can similarly be attached to the board by having bent ends. The radial wire can lie in the V-grooves between the upper ends of the legs of adjacent arcuate wires. Thus the grid can be a collection of separately-removable units for repair or replacement.
