Abstract: AN ELECTRO HYDRAULIC CONTROL WITH DEAD ZONE COMPENSATION          Abstract of the Preferred Embodiment The present invention is directed to an electro hydraulic control system wherein electric current output of the control is applied to an electric force motor to position a valve spool which in turn modulates fluid flow to a device to be controlled.  The valve spool, either to accommodate manufacturing tolerance or to assure zero output flow, in the neutral position, has a flow dead zone which requires a substantial valve spool travel to initiate fluid flow through the valve.  In the preferred device the manual control handle modulates the current output of the electric circuit which in turn proportionately modulates the position of the valve spool.  The electric circuit is provided with resistance means which are selectively inserted into the circuit to assure that sufficient output current is provided to the force motor to move the valve spool that amount necessary to initiate fluid flow upon a small movement of the control handle to compensate for the fluid flow dead zone in said valve.

Abstract: ABSTRACT OF THE DISCLOSURE   A mounting for an article, such as a high-voltage fuse. The article may be located inaccessibly behind a wall or accessibly in front of the wall. The wall may form a part of an enclosure and contains an opening. The article is affixed to one surface of a panel. The panel is attached to the wall so that it may be simulta-neously moved and translated (or pivoted) end-for-end (or side-for-side) relative to the opening to selectively move the article between its two locations. The panel covers or blocks the opening in both locations of the article. The panel may be attached to the wall by rollers mounted at or near one end of the panel and by links pivotally connected between the wall and the panel. The rollers are guided to move generally along or coplanarly with the opening by channels on the wall adjacent to the opening. In this way, substantially all of the movement and translation of the panel may occur in front of the wall.

Abstract: ABSTRACT OF THE DISCLOSURE     Valve Actuators A valve actuator has an electric driving motor for driving an output shaft through reduction gearing and manual operating means for driving the output shaft manually.          A drive transfer device for transferring the drive from the electric motor to the manual operating means incorpor-ates an electric switch which is operated by the initial movement of a manual operator of the drive transfer device to cause the motor if rotating to be brought to a stop. Continued movement of the manual operator causes the drive transfer device to transfer the drive to the output shaft from the electric motor to the manual operating means.          The drive transfer device advantageously includes a clutch between the motor shaft and a worm shaft forming part of the reduction gear.  The driven clutch member may form an integral part of a unit which is slidable as a sleeve along the worm shaft but is keyed for rotation to the worm shaft, the unit also having a pinion for meshing with a drive gear forming part of the hand drive.

Abstract: Abstract of the Disclosure PROCESS FOR THE MANUFACTURE OF FILM      The invention contemplates the manufacture of a wrinkle-free, amorphous, unoriented polyester film which is produced by an extrusion blowing process.  The process consists of extruding a bubble of polyester, expanding the bubble, and then collapsing the bubble at a temperature above the polyester's glass transition temperature to prevent the formation of wrinkles.  The collapsing step is effected through the use of a shroud which receives the bubble and has a low friction surface.    The process is illustrated in Figure 1 wherein a schematic representation of the process is designated by the number 10.  The molten polyester is extruded through a circular die 12 having an annulus 13.          Positioned immediately above die 12 is an air ring 14 having an annulus 15 through which passes a stream of air to inert gas.  The molten polyester is cooled by the air or gas such that its viscosity increases to produce an acceptance melt strength.  A stationary fluid bubble 18 or air or inert gas is located above the air ring and within the interior volume of the tubular polyester bubble 16.    As the polyester, usually polyethylene terephthalate or a copolymer thereof, is continuously extruded through the die 12, it is expanded by the fluid bubble 18 and then collapsed by means of a shroud 20.  The interior angle of the shroud may vary from 10 to 70 degrees with from 15 to 60 degrees preferred.          The polyester then passes through a slit 22 located at the apex of the shroud 20 and is thereafter pressed by means of nip rolls 24.  The polyester may then be wound.
