Abstract: METALLIC PROTECTOR FOR THREADED DRILL PIPE ENDS            A thread protector and a method for its production is provided.  The protector for threaded pipe ends comprises a metallic member having an undersized thread versus the thread of the pipe to be protected and a shock absorbing covering of plastic material on the metallic member threads. The covering shows a substantially uniform thickness over the region of the thread. If the pipe end comprises a sealing surface, then a corresponding undersized counter surface can be provided on the metallic member and can be equally provided with a uniform covering.          Advantageously, the threads of the metallic member do have to meet only coarse tolerances. The covering can be applied to the metallic member by electrostatic spraying followed by a fusing step.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus which controls lateral alignment of a belt arranged to move along a predetermined path. The belt is supported by a pivoted roller. A member having a pair of opposed, spaced flanges extending outwardly there-from is mounted slidably on a shaft extending outwardly from one end of the roller. A spring, contacting the flanged member, resiliently urges one of the flanges into continuous engagement with one side of the belt. Movement of the belt from the predetermined path slides the flanged member so that one of the flanges frictionally rotates a disc interposed therebetween. Rotation of the disc tilts the roller restoring the belt to the predetermined path of movement.

Abstract: ABSTRACT OF THE INVENTION           An accumulating conveyer is provided in which rollers are utilized which have a drive mechanism with a driven load-engaging portion in permanent frictional engagement with a driving portion.  The drive mechanisum includes an adjustable bias means so that the driving force between a driving portion and a driven portion is adjustable according to the characteris-tics of the loads to be conveyed.  A friction pad is positioned between a disc in the driving portion and a disc in the driven portion of the drive mechanisms; the two discs are urged against the friction pad by a compression spring.  When the weight of a load in contact with the driven portion is below a predetermined value, the friction between the friction pad and the two discs is sufficient to cause the two discs and the friction pad to rotate conjointly thereby coupling the driving portion to the driven portion.  When the weight of the load, or the weight of the load plus other resistance to movement of the load, exceeds the predetermined value, slippage occurs between the friction pad and the two discs thereby uncoupling the driving portion from the driven portion.  Only selected ones of the rollers include drive mechanisms, the number and spacing of rollers with drive mechanisms being determined by characteristics of the loads to be conveyed.  The conveyer can be used to column accumulate, and, with the addition of brakes actuated by a switching mechanism, to zone accumulate.

Abstract: Abstract of the Disclosure The incorporation of intercalated carbon/graphite in any of its forms such as powder, flake or fiber into an organic matrix results in a high strength, light weight composite with an electrical conductivity considerably higher than a similar product made with nonintercalated graphite.  A great variety of organic polymers may be used, such as epoxy, thermoplastics and thermoset resins.  Depending on the form of the intercalated graphite, fabrication techniques of extrusion, lay-up, injection molding and pressing can be employed to fabricate the parts from these composites.  A wide spectrum of properties is available from this type of composite in terms of strength and conductivity which will be useful for such widely ranging applications as aircraft structures and shielding for electronic equipment.
