Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a lug nut capable of manufacture on existing nut forming machinery having a continuous thread through the entire axially inner surface while having suitable drive means placed upon the axially outer surface 14 such as a conventional hex.  The lug nut has a conical bottom section for tight engagement and centering of a vehicle wheel upon a vehicle and an integrally formed flange at the other end thereof along with seat for acceptance of an insert in tight engagement therewith.  The insert can have a highly reflective surface to provide a safety feature for night time driving.  The insert is readily deflectable to a diameter at least as small as the insert receiving surface defined by the flange so as to allow the insert to pass through the open end, the insert having sufficient elastic memory to cause it to fit within the insert surface and against the seat with a tight fit without subsequent shaping of the insert receiving surface.  The flange has an inner diameter at least equal to the root diameter of the thread so that a mating threaded lug threaded into the nut does not threadingly engage the insert flange.

Abstract: SPECIFICATION                          FOR                    CARRYING HANDLE                           BY                   ROLLAND R. EDWARDS and LAWRENCE R. MOBLEY                          ABSTRACT           The handle includes an elongated grip constructed of a compliant material such as a molded foam rubber or plastic and has a pair of longitudinally extending parallel grooves on an upper surface, one adjacent each of the grip sides.  The grip is molded about an elongated rigid member which serves to reinforce the grip throughout its entire length.  A half-shell metal frame generally U-shaped in cross-section, has side edges received in the grooves of the grip and otherwise fits about the grip covering the top and part of the lateral sides.  Mounting stanchions are provided one for each end of the handle assembly and are affixed to the top surface of a luggage case, beauty case, or the like.  Each stanchion includes a stub shaft which is pivotally received through an opening in an end portion of the half-shell frame and reinforcing member.

Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for producing cellulosic pulp by the thermo-mechanical pulping method wherein wood chips are contacted with gaseous steam at a temperature and for a time sufficient to bring the temperature of the chips close to that of the steam, compacting the resulting steam treated chips while mechanically conveying the same to reduce the moisture content and produce a compacted moist mass, shred-ding the compacted mass while further conveying the same under more severe conditions than the original conveying and then passing the shredded mass into a refiner.      The apparatus of the present invention preferably takes the form of a pair of coaxially operating worm type conveyors with the end of one conveyor being journalled in the end of the other, and operating under conditions such that the second conveyor tends to pull the compacted mass faster than it is being delivered and thereby provides a shredding action to maintain a fairly uniform input into the refiner stage.

Abstract: ABSTRACT OF THE DISCLOSURE A lever-type load binder is disclosed in which the necessary force to draw the ends of the binder together is provided by a pivoting lever element. The binder employs a handle for tensioning and releasing the binder. The handle and lever element are constructed so that the handle positively engages the lever element to pivot the lever element on the tensioning stroke. However, the handle is employed merely to trigger the release stroke by rotating the lever element through dead center while the handle is out of the path of travel of the lever element. Because of this feature, the user is not endangered by a "flyback" of the handle when the binder is released.

Abstract: CLAMP                 Abstract of the Disclosure A spring steel wire is bent to have an open head from which criss-crossing limbs extend to form separated limbs each with two bearing points for gripping an object to be clamped.          Preferably each limb is a tilted "L" which is normally crossed twice over the other limb.  The head defines a hand or finger grip such that when the extremes of the separated limbs are placed in contact with a work to be clamped, the head affords a grip by which the entire clamp may be twisted with respect to the work and then pushed further onto the work such that the grip of the clamp on the work is increased because of the forces resulting from the re-orientation of the cross-over limbs.

Abstract: ABSTRACT OF THE DISCLOSURE A flying-saucer (flying disc) amusement device which is thrown by hand having greater stability and range than prior known devices.  The device achieves superior per-formance by the addition of "pimple" shaped or other shaped discrete spoilers on the upper surface of the flying saucer which creates a thin layer of turbulent air over the entire upper surface of the flying disc reducing aerodynamic drag.  The raised spoilers are arranged in annular rings which may cover part or all of the upper surface of the flying saucer.  The annular rings can be placed at varying intervals.  Each interval defines an "equator" which provides additional flight stability, helps to prevent "slicing" of the throw and also improves the range of the device.  When one or more annular rings of discrete, raised spoilers are placed at or near the periphery of the device (but not at or near the centre of the device), the discrete, raised spoilers add a small additional weight to the device which serves to dispro-portionately increase its angular momentum and, hence, its range.

Abstract: FLUID DISPENSING SYSTEM     ABSTRACT OF THE DISCLOSURE           A system for dispensing fluid from a container.  The container is pressurized by supplying gas into the container thereby forcing the fluid out of the container through a siphon tube and an outlet valve in the container.  The system utilizes a valve assembly having two valves, one for enabling the flow of the gas into the container and the second for allowing the flow of the fluid out of the container.  The valve ??? bly is  mounted in a neck member that is secured to an opening in one of the walls of the container.  Arranged within the neck is a deformable seal that is  compressed between a body portion of the valve assembly and an inner surface of the neck member.  A non-threaded retaining ring holds the valve body portion of the valve assembly within the neck member and serves to apply the force to the valve body portion for compressing the seal.  In order to avoid the existence of a sump within the valve structure, which could damage or contaminate the fluid dispensed from the container, the top of the valve assembly is substantially flush with the top of the neck member.  A coupler is connected to the neck member and has a probe capable of being moved between an open position and a closed position.  In its open position, the probe serves to open the two valves of the valve assembly for enabling gas to be fed into the container and fluid to be dis-pensed from the container.

Abstract: ABSTRACT A proportional fuel fuel control (11) regulates the fuel flow (Wf) from a hydromechanical unit (36) based upon an error signal (E) representing the difference between a demanded speed signal  (Nd) and an actual speed signal (Nh).  The demanded speed signal (Nd) is generated by an integrator (32) as the time integral of the least of a plurality of acceleration terms (Aa, Ab, Ac, Ad) selected by a select low gate (38). The demanded acceleration term (Aa) is generated by junction (26) as the difference between the demanded signal (Nd) and a scheduled speed signal (Ngs).  Stress acceleration terms (Ac, Ad) are generated by junctions (48, 50) and scheduling means (42, 44) which form stress limiter circuits.  A stall acceleration term (Ab) is generated by a junction (46) and a scheduling means (40) which form a stall prevention feature.                           (Figure 1)
