Abstract:
An apparatus (10) and method for selecting a fluid material to be supplied to a material applicator (24) from a plurality of fluid materials (23), the material applicator being located in a hazardous area (12), includes a control circuit (26) located in a non-hazardous area (11) for generating a coded address signal representing a selected fluid material and for generating a predetermined amount of electrical power, a valve selection circuit (27) located in the non-hazardous area and connected to the control circuit and being responsive to the coded address signal for generating the predetermined amount of electrical power at a selected one of a plurality of outputs corresponding to the coded address signal, and a valve actuation circuit (28) located in the hazardous area and including a separate valve (22) connected to each of the valve selection circuit outputs. The valves (22) includes electrically actuated valves (46) mounted on and pneumatically actuated valves (47) releasably retained in a manifold assembly (41) formed of a plurality of blocks (42,43,44) each having a material distribution passage (62) connected to the material applicator (24) and a material inlet passage (60) connected to the fluid material supply (23). The control circuit (26) limits the predetermined amount of electrical power to a value sufficient to actuate one of the electrically actuated valves (46) and permit fluid material flow from the material inlet passage (60) to the material distribution passage (62) through the associated one of the pneumatically actuated valves (47).

Abstract:
An electro-optical position transducer employs an optical mask having a number of parallel channels formed of alternating opaque and transparent sections extending along the direction of motion of a movable member. One channel has opaque and transparent sections, and the section lengths correspond to the smallest measureable increment. This channel generates the least significant bit of the code. A pair of channels, displaced linearly relative to one another, are provided for each of the higher order bits. Pairs of LED's and photo-transistors are provided for each channel and extend in a line normal to the length of the channel. The outputs of the photo-transistors are decoded so that all transitions between binary values in the output signal occur in synchronism with transitions of the least significant digit.

Abstract:
A versatile output card circuit capable of switching a wide range of voltage levels for use with the central processing unit of a computer or microprocessor controller. The versatile output circuit includes an isolation switching means circuit for electrically isolating a second predetermined range of load voltage while responding to a first predetermined range of signal output voltage by switching the second predetermined range of load voltage to a desired load and an indicating means circuit coupled to and responsive to the isolation switching means circuit for indicating when the second predetermined range of load voltage has been switched to the load.
