An apparatus and method are provided for automatically positioning a scanning device such as a video camera at selected locations of a substantial area of operation to permit the scanning device to selectively scan different phenomena within the realm of the different areas which may be scanned thereby. In one form, the scanning device is supported by a carriage which is movable along a trackway and is automatically or remotely controlled in its operation. The scanning device is also movable on ...

A system for exposing artworks on a photosensitive surface includes a photoexposure device having a cathode ray tube energized to exhibit luminous symbols, one at a time, on its face. An associated optical system projects a real image of the luminous exhibited symbol onto a sheet of photosensitive material. Symbol generating signals supplied to the cathode ray tube are derived from a store wherein they are defined in relation to a single fixed or standard angular orientation relative to the face...

A microprogrammed peripheral controller includes a deskew buffer including a plurality of clocked storage devices. Pairs of the clock storage devices of each register provides storage for a single information channel. Each channel is driven from a separate clock circuit which is enabled for operation only when circuits associated with the channel detect that information signals are being received by the channel indicating that the channel is "active" at the start of an actual record. The circuit...

A method and apparatus providing positive control of steam conditions during start up, shutdown and low load operation of the vapor generator including by-passing vapor around the heating, reheating and turbine zones for discharge to the condenser and using the by-passed vapor to attemperate the outflow from the heating and reheating zones.

An electronic phototypesetting system utilizing a single cathode ray tube (CRT) timeshared as (1) a flying spot scanner and (2) a photo exposure device. In the scan mode, the CRT scans an optical representation of the next character to be displayed by the photo exposure device to develop electronic font digital data signals. The digital data is stored in a single character digital memory and is read out during the exposure mode to display the character on the CRT for imaging onto photosensitive ...

System for counting components produced on machine tools such as automatic nd semi-automatic lathes. Comprises first switch or valve operated by a component positioned in the machine tool and second switch or valve operated when machine cycle is initiated. Both switches or valves are connected to a counter in such manner that a count is recorded only if both switches or valves are operated.

A steering system comprises a pair of fluid actuators connected to effect turning of wheels of a vehicle when actuated. Each of the actuators is a cylinder divided into two fluid chambers of unequal volume by a piston. Fluid flow into certain chambers of each cylinder effects steering in one direction and fluid flow into the other chambers of each cylinder effects steering in another direction. Respective fluid controllers are associated with each of the cylinders. Each of the fluid controllers ...

A seal system is described for a shaft which extends between two regions which are to be isolated. The seal includes a seal housing which defines an annular land facing on the shaft and which defines an annular labyrinth facing on the shaft. The housing also defines a collection cavity communicating with the spaces between the land and the shaft and between the labyrinth and the shaft. Fluids compatible with the fluids in each of the two regions to be isolated are introduced, respectively, to th...

A hypothermia system for therapeutic use, particularly in hospitals, to cool or heat patients, the hypothermia system including a novel fluid pressure operated impeller driven pump effective to recirculate heat transfer fluid through a virtually closed fluid circuit including a hypothermia pad.

1. Means for guiding an object along a line-of-sight path from a launching site to a target comprising an object having an aerodynamically stable shape with a front to rear axis oriented during flight to extend substantially on the line-of-sight between the launching site and the target, means at the launching site for launching the object on a course toward the target, means for causing the object to roll about its axis at a predetermined roll rate, a light source mounted on the object in posit...
