Abstract: ABSTRACT        A laminated tubular structure is obtained by a process in which a fabric sleeve is applied about a tube of thermoplastic polymer, following which plugs are inserted into the opposing ends of the liner.  A liquid, such as water, is then introduced to the liner, and the liner is rotated about a horizontal axis while heat is applied to the exterior surface of the liner, causing the surface to become molten.  The heat also causes vaporization of some of the liquid in the liner and the resulting vapor pressure causes the molten surface of the liner to expand radially into the interstices of the fabric sleeve.  The inner surface of the liner remains solid and form-maintaining by reason of the liquid within the liner and heat absorbed on vaporization of liquid.  Upon cooling, there is obtained a good mechanical bond between the liner and sleeve.  The liner-sleeve composite can be further reinforced by a surrounding layer of a thermosetting resin containing reinforcing fibers, the resin layer being bonded to the composite by means of the sleeve.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an optical system which will enable easy use in the field.  Known systems either require sample and reference targets to be imaged within the telescope field or do not enable accurate identification of the measuring field in a view finder.          The present invention overcomes this problem by providing a system having a first branch and a second branch which receive light from a sample and reference target respectively.  A shutter sequentially allows light from the two branches to pass to a mirror having a slit, reflective portions and transparent portions.  Light from the first branch passes through these portions to a detecting branch and some light is reflected through a lens to an eye piece.  Similarly some light from the second branch passes through the mirror to the eye piece and some light is reflected to the detecting branch.  Accordingly the measuring field can be accurately identified by looking through the eye piece whilst at the same time light is directed to the detecting branch for analysis.

Abstract: IMPROVED SPEECH CODING METHOD AND DEVICE       FOR IMPLEMENTING THE IMPROVED METHOD                     Abstract Method for coding a speech-originating signal.  The spectrum of the initial signal covering a frequency range of 0-4000 Hz is split into 16 subbands, each one containing 12-bit coded samples. The samples of the 16 sub-bands are requantized in BCPCM at dynamically variable bit rates.  For this, the sample flow of the sub-bands is divided into blocks of a given duration, then each block is processed for deriving therefrom two scale factors, the difference of which is analyzed to define the sample block as transient or non-transient block.  For each non-transient block, only one scale factor is retained, whereas for a transient block, both scale factors are retained.  The signal samples of the 16 sub-bands are then dynamically requantized with an overall number of bits depending on whether the block considered is transient or non-transient.

Abstract: Abstract of the Disclosure An improved easy opening container end is disclosed of the type wherein an opening tab is attached to a wall of a can end closure at a fulcrum adjacent to a primary score line.  The primary score line circumscribes a pour opening panel except at a hinge area. The forward portion of the opening tab is adapted to depress the pour opening panel into the container to expose a pour opening when the opening tab is pivoted about the fulcrum. The opening tab is attached to the wall by means of a rivet. One secondary score line intersects with the primary score line and projects away from the pour opening panel on one side of the rivet and another secondary score line, also intersects with the primary score line, and projects away from the pour opening panel on the other side of the rivet. In this manner, after the primary score line is severed and the pour opening panel is depressed, the opening tab may be retracted from the vicinity of the pour opening panel by severing the secondary score line so as to provide easy removal of the contents of the container and to expose an underportion of the wall for the reading of promotional indicia.         In another embodiment, a region of the wall contiguous with the pour opening panel and further defined by a secondary score line may be provided such that after the depression of the pour opening panel, the pour opening panel, and the region attached thereto by means of a hinge area may be severed from the container and along with the opening tab.

Abstract: ABSTRACT OF THE DISCLOSURE          A low-traction barrier method and a apparatus are provided for preventing the traverse of gypsy moth caterpillars or similar destructive crawlers across the barrier.  A strip of slippery, com-pliant material has low-traction characteristics with respect to gypsy moth caterpillars and thus initially arriving caterpillars do not become stuck on the harrier and do not form "bridges" across the barrier over which later arrivals can crawl.  Self-adhering adhesive material extends longitudinally on one surface of the strip along at least one of its longitudinal margins.  The strip is wrapped around and is adhered to the trunk of a tree to provide a barrier for preventing gypsy moth caterpillars from traversing either up or down the tree trunk by causing them to slip off of the barrier and fall to the ground whenever they attempt to traverse it.          The compliant characteristics of this low-traction strip enable the adhesive coated margin of the strip to be inserted into indenta-tions in the rough bark of a tree trunk as the strip is being wrap-ped around the tree for preventing the occurrence of vertical tun-nels underneath the barrier through which smaller caterpillars could crawl.  By positioning the low-traction strip around the trunk below the foliage of the tree, ascending caterpillars fall before they roach the foliage.  Descending caterpillars also fall while attempting to traverse the strip and thereafter are preven-ted from ascending back up the tree by the low-traction strip.  In one aspect of the invention, adhesive backing extends along the upper longitudinal margin of one side of the slippery compliant strip.  This upper margin of strip is folded by crimping between the thumbs into approximately equidistantly spaced pleats as it is being wrapped around the trunk to form an outwardly flared, down-wardly extending skirt from the main body of the strip.  In this advantageous manner, the barrier formed by the flared skirt approx-mately doubles the slippery surface area over which a caterpillar must traverse in order to climb up or down the tree, thus greatly enhancing the probability that the caterpillar will fall.  More-over, the skirt requires ascending caterpillars to negotiate a com-plete 180° inversion around the lower edge of the strip with gravi-tational forces acting against them, further impeding their tra-verse.
