Abstract: HIGH TORQUE PLUG VALVE ACTUATOR             ABSTRACT OF THE DISCLOSURE     A high torque actuator for a plug valve of the type having a body with a central chamber having diametrically opposed inlet and outlet ports and a plug within the chamber having a transverse passage therethrough and an upstanding stem.  The plug has a first, upper, valve-open position with its transverse passage in alignment with the inlet and outlet ports of the chamber, and a second, lower valve-closed position wherein its transverse passage is oriented at 90° to the chamber inlet and outlet ports and seal means on the plug are in sealing engagement with the chamber walls about the inlet and outlet ports.  Means closing the top of the chamber through which the plug stem extends in fluid-tight fashion.  The actuator comprises a hollow cylindrical yoke the lower end of which is operatively affixed to the plug valve with the plug stem extending axially into the yoke.  A valve stem is rotatively mounted at the upper end of the yoke and has a lower threaded portion extending axially into the yoke.  The valve stem is threadedly engaged with a drive cam non-rotatively mounted within the yoke and axially-shiftable by the valve stem within the yoke.           The lower portion of the drive cam has a diametrically opposed identical pair of sloped drive slots therein and is received in the axial bore of a coupling and is affixed thereto by a drive pin passing through the drive cam drive slots with its ends mounted in diametrically opposed perforations in the coupling.          The upper end of the plug stem is non-rotatively affixed to the cylindrical coupling. The coupling has diametrically opposed cam slots formed therein.  The yoke supports a cam follower for each cam slot. The cam slots are so configured that upon turning the valve stem in one direction, the plug in its valve-open position will be simultaneously partially lowered and turned 90° and thereafter lowered without rotation to its valve-closed and sealed position.  Upon turning the valve stem in the opposite direction, the plug will first be lifted vertically without rotation out of sealing relationship with the chamber inlet and outlet ports and thereafter simultaneously lifted and rotated 90° to its valve-open position.  The drive cam and its slots impart additional torque to the coupling during rotation of the plug.

Abstract: MATERIALS TRANSFER SYSTEM AND METHODOLOGY               ABSTRACT OF THE DISCLOSURE          A method and system are provided for continuously conveying hard particulate material of non-uniform size, like coal.  A high pressure transfer device has high and low pressure feed and discharge lines extending to and from it, and a screen arrange-ment for allowing liquid and fines to pass from the low pressure feed line to the low pressure discharge line, while stopping large particles.  An excess accumulation of fines is prevented by providing a screen assembly vertically above the high pressure transfer device.  Level control in a hopper - which provides the low pressure feed line - is accomplished merely utilizing an overflow technique.  The concen-tration of particles in the liquid in the high pressure discharge line is maintained about 50% by withdrawal a portion of the liquid (while still under pressure) from the high pressure discharge line, and returning it to the high pressure feed line. density measuring device downstream of the liquid withdrawal automatically controls the amount of liquid withdrawal.

Abstract: ABSTRACT OF THE DISCLOSURE     An automatic level control (ALC) circuit is used with a light beam scanning apparatus to inspect printed circuit boards containing a pattern of conducting surfaces on an insulating substrate.  Light interaction with the conductors produces a first set of signals called conductor signals while light interaction with the substrate produces a second set of signals called substrate signals.  A first corrected reference signal corresponding to the conductor signals is generated and provided to a summing circuit where it is summed with conductor and substrate signals from the scanning apparatus.  When the first reference signal is summed with conductor signals a near zero level summed conductor signal is produced.  Substrate signals added to the fixed level first reference signal produce summed substrate signals with a non-zero value.  Sub-sequently a second corrected reference signal is generated.  Thereafter, both summed conductor and summed substrate signals are provided to the multiplier circuit along with the second corrected reference signal. The adjusted sub-strate signals will have a signal level nearly equal to the preselected signal value for all printed circuit boards which undergo inspection.  The adjusted conductor signals will have a near zero signal level for all printed circuit boards undergoing inspection.  In this manner, the ALC circuitry provides uni-form adjusted substrate and adjusted conductor signals for all printed circuit boards undergoing inspection.

Abstract: ABSTRACT OF THE DISCLOSURE     A cold weather breathing device designed to use body heat to heat the air being inhaled by the user comprises a mouthpiece, a valve unit containing first and second valves in air communication with the mouthpiece and a conduit extending downwardly from the valve unit.  The first valve provides air communication between the conduit and the mouthpiece when the user inhales, and blocks said aircommunica-tion when the user exhales.  The second valve provides air communication between the mouthpiece and an exhaust opening of the valve unit when the user exhales, and blocks such air communication when the user inhales.  A shield unit including a substantially air impervious member is coupled to an end of the conduit remote from the mouthpiece.  A plurality of projections extend from the air impervious member for spacing the air impervious member from the body of the user to provide at least one air passage between the air impervious member and the body of the user, the at least one air passage being in air communication with the interior of the conduit.          In this manner, body heat is used to effectively heat the air being inhaled by the user via the air passage, conduit and valve unit.  Swivel connections and hinge connections may be incorporated in the con-duit, and/or an improved dual-flap valve arrangement may be provided to reduce vibration and to provide a faster acting valve device.  Further disclosed is a deflector baffle arrangement which promotes synchronous valve cycling even under severe conditions and a cool air bypass in the conduit of the device to enable the user to mix cool and warm air so as to provide the desired temperature of the breathed in air.

Abstract: STEERING ARRANGEMENT FOR AN OFF-HIGHWAY ARTICULATED VEHICLE        Abstract of the Disclosure In an articulated combine, front and rear bogies are connected by spaced-apart upper and lower links.  The upper link permits relative lateral movement between the bogies due to oscillation about a longitudinal axis.  At the lower link, a rigid tongue of the rear bogie is connected to the front bogie by a ball hitch.  Steering of the vehicle is through a pair of hydraulic cylinders controlled in part by a feedback cylinder. The steering cylinders are connected together to the rear bogie, at a common ball joint.  All other connections of the hydraulic cylinders are ball and socket type and their effective pivot centers define respective transverse (kneel) and longitudinal (oscillation) axes, intersecting at the ball hitch.  Forward connections of the steering cylinders and one end of the feedback cylinder lie on the kneel axis.  The common rearward steering cylinder connection and the connection of the other end of the feedback cylinder lie on the oscillation axis.  This arrangement isolates the steering system from oscillation and tipping movement of one bogie relative to the other in the sense that such movement, by itself, does not directly impose length changes or axial loading in the steering system cylinders.

Abstract: CENTRIFUGAL ACTUATED FRICTION CLUTCH    WITH A HYDRAULIC APPLY PISTON            Abstract of the Disclosure A friction clutch has an apply piston slidably disposed in a clutch housing and cooperat-ing therewith to form an apply chamber and a feed chamber.  The effective area of the apply chamber is greater than the effective area of the feed chamber.  Pressurized fluid for clutch engagement is distributed directly to the feed chamber and from there through a restricted passage to the apply chamber.  Fluid pressure in the feed chamber is established by a variable regulator valve and operates on the effective area of the piston to urge disengagement of the clutch.  Fluid pressure in the apply chamber is established by a pair of centrifugal exhaust control valves having indi-vidual speed-pressure relationships.  The fluid pressure in the apply chamber acts on the effective area thereof and urges engagement of the clutch. The pressure level  in the feed chamber controls the minimum speed of engagement which can be varied by varying the feed pressure.  The clutch can be designed to engage at one speed and dis-engage at another speed by changing the feed pressure level after clutch engagement.

Abstract: DEVICE FOR SEPARABLY CONNECTING NEIGHBORING PANELS IN              CONCRETE FORMS            ABSTRACT OF THE DISCLOSURE           A device which serves to temporarily and releasably connect two neighboring panels of a concrete form has two sections which are coupled to each other by a pivot pin, and two parallel projections each of which is carried by a discrete section.  One of the projections is rigidly attached to the respective section, and the other projection is rotatable relative to its section and can be locked to the flange of one of the panels after passing through a keyhole-shaped opening of such flange.          The other projection then extends into the opening of the flange which forms part of the other panel.  The section for the non-rotatable projection is L-shaped and the other section is a link which can turn about the axis of the pivot pin.  The non-rotatable projection is secured to the free end portion of one leg of the L-shaped section and the pivot pin connects the link to the free end portion of the other leg.  When the projections are properly inserted into the openings of flanges of two neighboring panels, one of the panels can be moved along an arc about the pivot pin away from the surface of the poured and hardened concrete and is then ready to be fully separated from the remainder of the form in response to extraction of the respective projection from the opening of its flange.  The device can be used with equal advantage for facilitating movement of a panel to the operative position; it is particularly suited for temporary coupling of neighboring panels which form part of a ceiling mold.
