Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus and method for reducing material accumulation on processing equipment caused by electrostatic charge.  By proper selection of materials, the equipment is designed to automatically develop a charge of the same polarity as that on the material being processed and thereby repel the material.  The selection can be based on the relationship of the materials in the Triboelectric Series.  The processing equipment is also electrically insulated from discharge paths so that the charge developed will not be dis-sipated or require high current generation to maintain the voltage required to repel the material particles.

Abstract: This method consists in preparing by extrusion an inner plastic tube (100) and in forming around the latter a metallic tube (300) which is covered by an outer plastic layer (900). The metallic tube (300) is formed to an internal diameter substantially greater than the external diameter of the inner plastic tube (100). This metallic tube (300) is closed by welding (40) edge to edge without overlap. The excess in diameter of the metallic tube (300) is reduced without drawing or stretching of the latter. 
<??>Adhesive coverings (200, 700) may be interspersed between the various constituent layers or tubes and a braid (800) may be interspersed between the metallic tube (300) and the outer plastic layer (900).

Abstract: PRINTER FRAME ASSEMBLY AND METHOD OF ASSEMBLY                   ABSTRACT OF THE DISCLOSURE A printer frame assembly having snap-together parts includes a base member, two side frame members, resilient cushions and an impact platen.  The base member has locating receptacles to position the side frame members and interlocking flexure latches to snap-lock with corresponding locking surfaces located on the two side frame members.  The interlocking flexure latches provide a bias to align the side frame members in a front-to-back direction and lateral alignment channels to prevent lateral displacement.  The resilient cushions are positioned between the bottoms of the side frame members and the base member to urge the interlocking flexure latches and locking surfaces into secure engagement and to eliminate any clearances between the side frame members and the base member.  The impact platen serves as a structural member of the frame and is positioned intermediate the two side frame members.  The method of frame assembly comprises locating the resilient cushions on the base member, snapping the side frame members into respective locating receptacles and  flexure latches of the base member, thereby trapping the resilient cushions, and locking the impact platen between the two side frame members.

Abstract: ABSTRACT      Ideas on book supports already developed by inventors have generally aimed at a simple, compact, collapsible, and economical product.  From the point of view of function, however, only supporting a book in an inclined position can be considered satisfactory, but not when this comes to the way the pages of a book are held open.    Of the three main approaches introduced for holding the pages open, the one using a flexible finger-like member that presses against the pages has adjustment difficulties.  The one dependent on tight hinges for its proper function has limited life span due to wear.  Finally, solid stops in front of the lower end of the book obstruct the free turning of the pages.    The present invention, without compromising on simpli-city, compactness and economy, is placing particular emphasis on the originality of the page-holding method.  The pages here are held open by two finger-like means which slide easily back and forth in front of the open book.  They become firm when slightly presses against the pages but go completely out of the way when pulled backwards.     _ 1 _

Abstract: Abstract of the Disclosure The flow rates in the cooling circuits of the apparatus  can  be  controlled  with  the  aid  of  a computer by means of ceramic turning valves.   The computer is connected to the central computer of a plastic injection molding machine.   The valve body disks,  lying  under  constant  pressure  via  ceramic sealing surfaces against valve seat disks,  can be turned by means of pulse-controlled electric motors.          Each fitting has a valve channel between the channel section of the supply channel and the channel section of the discharge channel which is covered by a valve seat disk and which forms a valve chamber.   This achieves the effect that the deviations from the set temperature in the temperature-critical zones can be substantially  reduced  with  acceptable  technical expenditure.  The temperature constancy achieved may be maintained for a virtually unlimited time without appreciable maintenance work.

Abstract: METHOD AND APPARATUS FOR FORMING AN   INSULATED OIL WELL CASING          Abstract of the Disclosure A method and apparatus for forming an electrically conductive externally insulated casing for an oil well of the type in which the casing carries electrical current to a primary heating electrode positioned downhole, using multiple prefabricated casing segments; each casing segment is a long steel pipe having a female thread coupling on one end and a male thread on the other end.  Each segment has an insulator covering, over substantially all of its length, that has a figure of merit   of no more than 4 x 108 so that the the shunt impedance of the casing to ground can be kept substantially greater than the spreading resistance of the primary heating electrode.  The preferred casing segment insulation is in two layers, including a hard, durable inner layer subject to water degradation and an outer water-impervious layer usually applied as tape.  The uninsulated portions of joints between segments are covered with an insulator cement in the field and then further covered with a water-impervious tape that overlaps the water-impervious layers on two segments.
