Abstract: ABSTRACT                      VACUUM CURET  A vacuum curet of novel design having a central portion which is tapered and an internal lumen which is preferably also tapered.  This provides a curet which is rigid over its central and proximal end (i.e. the end that fits into a vacuum source) and maxi-mal flexibility and small external diameter at its distal end portion.  Further advantages of this arrange-ment are reducing the possibility of perforation (due to the flexibility of the distal end portion), better "feel" (due to the rigidity of the central and proximal end portion), and decreased trauma due to the thin wall thickness of the proximal end portion and a corres-ponding reduction in outside diameter for a given or required lumen diameter.  The lumen of this design may also be mass produced.  In an additional embodiment, there is a novel design on the tip openings at the distal end, which further minimizes the possibility of perfora-tion.   1.

Abstract: ABSTRACT OF THE DISCLOSURE         A segmented thermoplastic copolyester elastomer containing recurring polymeric long chain ester units and short chain ester units.  The long chain ester units are derived from dicarboxylic acids and poly(alkylene oxide) glycols.  The segmented copolyester contains about 25-90 percent by weight of at least two short chain ester units, about 45-95 percent of the total of all short chain ester units have no side chain and have a melting point of at least 150°C if in the form of a high molecular weight polymer derived only from short chain ester units.  About 5 to 55 percent of the total of all short chain ester units have side chains said side chains having a length between 7 and 25 carbon atoms.  Such segmented thermoplastic co-polyester elastomers are suitable for certain specialty applications such as, for example, impact absorbers, coated fabrics, low pressure tubing and other uses where low hardness and modulus combined with high tear strength, high melting points, rapid crystallization rate, and good flexibility are needed.

Abstract: Abstract of the Disclosure A torsion bar is provided for stiffening lightweight paneled doors having a thin wood or composition panel and metal stiles and rails around the periphery so that the doors do not twist or rack. The stiffener has a torsion bar extending the height of the door and an L-shaped clamp at each end for connection of the bar to the door.   Each clamp has a flat face sheet held tightly against the face of the door by sliding a barbed edge under the rail.  The other sheet forming the L-shaped clamp has a window through it complementary to the cross section of the torsion bar and defining a centrally located web of metal near the free edge of the clamp remote from the face of the door.     To lock the clamp in place on the torsion bar the web is twisted out of the plane of the sheet, preferably by tilting a pin in a hold through the web, which pulls the sides of the window tightly against the torsion bar.   In a preferred embodiment the torsion bar is a square, roll formed, box section.

The thermally crystallizable glass composition is produced by a process involving the steps of providing a quantity of uncrystallized chips of crystallizable glass having a thickness of about 20-25 mils, and a quantity of essentially fully crystallized glass having a particle size ranging between about -20 and +80 U.S. Series Sieve screen size; reducing the particle size of the uncrystallized glass and fully crystallized to a particle size range wherein essentially all of the uncrystallized glass and fully crystallized glass particles are less than 100 U.S. Series Sieve screen size and wherein between about 65-78 percent by weight of the uncrystallized glass and full crystallized glass particles are less than 325 U.S. Series Sieve screen size; blending the fully crystallized glass particles together with the uncrystallized class particles in a ratio of between about 100-225 parts by weight of crystallized glass particles to one million parts by weight of uncrystallized glass particles to produce a uniform "master blend" of finely comminuted, crystallized and uncrystallized glass particles. The "master" blend is then used for blending with uncrystallized particles of thermally crystallizable glass having a composition similar to that of the "master blend" and having s particle size such that essentially all of the uncrystallized particles are of -100 U.S. Series Sieve screen size and such that between about 65-78 percent by weight are of -325 U.S. Series Sieve screen size; the ratio of "master blend" to uncrystallized glass particles being selected to produce a homogeneous resulting blend or "product blend" composed of from about 1-10, or more preferably 2-7, parts of fully crystallized glass particles to each one million parts of uncrystallized glass particles.

Abstract: SAFETY SKI BINDING                  ABSTRACT OF THE DISCLOSURE    Safety ski binding including an intermediate plate and improved boot gripping means.  A plate intermediate the boot and ski is mounted onto the ski by centrally positioned pivot means and held normally aligned with the ski by heel means which permits only limited swiveling movement of the plate with respect to the ski and only limited movement vertically of the plate away from the ski.  Conventional toe engaging means are provided between the plate and the ski boot and said heel means also engage the heel of the ski boot, said means being arranged for releasing the ski boot from the plate upon movement of the plate a predetermined distance either vertically away from the ski or pivotally laterally of the ski.  The ski boot is thus freed from said plate and said plate remains with the ski.  After the ski boot is so freed from the ski the plate returns to its aligned position with respect to the ski and the apparatus is ready for re-engagement of the boot therewith.
