Abstract: ABSTRACT         The ends of heat-recoverable polymeric sheet material are joined by overlapping the ends and bonding them together by means of a laminar panel comprising a layer of a cross-linked hot-melt adhesive coated on one surface of a reinforced polymer layer.  The panel has a length approximately equal to the width of the sheet material being joined and is disposed, adhesive side down, so that approximately half of its adhesive coated sur-face contacts the sheet material on either side of the line defined by the uppermost of the overlapping ends.  The panel is heated to activiate the adhesive and form a secure bond joining the ends.  Heat-recoverable sleeve can be made by joining the two ends of a single length of heat-recoverable sheet material.

Abstract: ABSTRACT       In known separator devices for transfer medium, a separating belt has been disposed between an image-bearing member such as a photosensitive medium or the like and a transfer medium to which the image on the image-bearing member is to be trans-ferred, and the separating belt has been fatigued by being sub-jected to localized friction with respect to the image-bearing member and/or a rotating member for effecting the separation.     In the present invention, the separating belt is gradually moved in accordance with the separating device, whereby such localized friction is reduced and the belt need not be replaced as frequently.

Abstract: METHOD OF LEVEL SENSITIVE TESTING A FUNCTIONAL        LOGIC SYSTEM WITH EMBEDDED ARRAY                     Abstract Level sensitive testing is performed on a generalized and modular logic with embedded array system that is uti-lized as an arithmetic /logical unit in a digital computer.          Each arithmetic/logical unit of a computer is formed of arrangements of combinational logic networks, arrays and storage circuitry.  The storage circuitry has the capability for performing scan-in/scan-out operations independently of the system input/output and controls.  Using the scan capa-bility, the method of the invention provides for the state of the storage circuitry to be preconditioned and indepen-dent of its prior history.  Test patterns from an automa-tic test generator are cycled through the networks of com-binational logic and arrays and their respective associated storage circuitry for removal through the scan arrangement to determine their fault status.    The above ABSTRACT is not to be taken either as a com-plete exposition or as a limitation of the present invention, the full nature and extent of the invention being discern-ible only by reference to and from the entire disclosure.

Abstract: Abstract of Disclosure A plastic coil bobbin has a recess with the precise dimensions of a thermal fuse.  On one side, the recess is open so that, as the coil is wound on the bobbin, successive layers of coil wire form a wall-like surface closing that open side.  As the fuse is press fit into the recess, it is also forced into intimate contact against the wall of wire. Thus, the only material between the fuse and wire is a thin plastic shell forming the fuse housing.  Since the fuse rating takes this wall thickness into account, there is effectively no thermal insulation between the coils and the fuse.  Accordingly, under overheating conditions, the fuse opens a circuit when there is overheating and before a fire can start.

Abstract: Synthetic absorbable sutures are prepared from copolyoxalate polymers having isomorphic sequences. The polymers are derived from mixtures of cyclic and linear diols, each having the same carbon chain length of 6 or 8 atoms. The cyclic diol may be aliphatic or aromatic. The diols are polymerized with dialkyl oxalate, preferably in the presence of an inorganic or organometallic catalyst, to obtain a highly crystalline isomorphic copolyoxalate polymer which is melt extruded and drawn to form oriented filaments. The filamenes are characterized by good initial tensile and knot strength and a high order of softness and flexibility. When implanted in living animal tissue, the fibers have good strength retention over a period of at least 21 days and eventually absorb with a minimal degree of adverse tissue reaction.

Abstract: ABSTRACT OF THE DISCLOSURE        A bifocal lens is produced on either a previously formed blank lens, or completely in a singular casting between two molds.  The bifocular lens is obtained by supporting a bifocal lower mold having a recessed bifocal well area on its concave surface and filling the lower mold with a resin material.  By positioning an upper mold in vertically spaced relationship to the lower mold, the resin material is displaced to extend between the overlapping surfaces of the molds to form the configuration of the bifocal lens with a bifocular portion on the convex lens surface corresponding to the bifocal well on the lower mold.  Curing of the. resin material situated between the molds and cooling the resin material and the molds forms the complete lens.          Thereafter, a separating of the bifocal lens from between the molds leaves the bifocal lens in a position to be completed and installed in a pair of eyeglasses.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus is disclosed for binding an article with strap.  A strap is encircled about the article to form a loop with the leading end segment of the strap over-lapping an adjacent segment of the strap.  The leading end is gripped to prevent further feeding and to subsequently restrain it against movement relative to the article while the trail-ing portion of the strap is retracted to draw the loop tight around the article.  While holding the leading end segment of the strap and an adjacent overlapped segment against relative movement  and under tension, either 1) a joint is first formed in the overlapping segments and the tension is then gradually released in the trailing portion of the strap to avoid shock loading of the joint and the machine or 2) the tension is first released only in the trailing portion of strap and the joint is then formed with tension in at least the overlapped segment adjacent the strap free end.  The pre-ferred embodiment of the apparatus is used with metal strap and forms an interlocking slit-type joint in the overlapping strap segments with a notcher jaw assembly coacting with a notcher punch, both of which also function prior to joint formation to hold the overlapping strap segments together against relative movement and to maintain tension on the overlapped segment adjacent the strap free end while tension is released in the trailing portion of strap.
