The conduit is fabricated by solid state hydro-static extrusion of a substantially non-oriented semi-crystalline thermoplastic polymer preform which may contain up to about 60 weight percent filler. The polymer is sub-stantially simultaneously elongated in both circumferential and axial directions by compressive forces with the circum-ferential elongation being at least 100 percent. The apparatus used to produce the product is a hydrostatic extrusion press which includes an annular orifice in which the thermoplastic polymer is elongated substantially simultaneously circumferentially and axially with the circum-ferential elongation being at least 100 percent. Means for maintaining the rigidity of tooling and the hydrostatic extrusion fluid pressure while providing a film of the fluid on the preform for lubricity are provided in the apparatus. -1-A sheet substantially uniform in thickness and having substantially the microstructure and properties of the conduit and excellent drawability may be made from the conduit.

Abstract: ABSTRACT OF THE DISCLOSURE           A universal front anchoring system for reusable impact attenuation devices is provided.  Buffer elements are positioned in an ordered array extending forwardly of a rigid backing member adjacent to a fixed structure.          Diaphragm members are interposed in the array and ex-tend laterally outward of the array at fixed intervals.   Fender panels are pivotally coupled to laterally extend-ing ends of the diaphragm members and extend rearwardly from their associated diaphragm members and partially overlap the fender panels coupled to the succeeding diaphragm members.  Nonrigid means such as restraining cables and secondary cables interconnects the backing member and the diaphragm members.  A pair of laterally spaced anchor assemblies is connected to the nonrigid means at the forward end of the impact attenuation device.          The anchor assemblies are adapted for fixing to the ground and are symmetrical, identical and interchangeable with each other.  Preferably, the anchor assemblies have a large central mounting bracket for securing one of the restraining cables and two smaller mounting brackets laterally spaced on opposite sides of the central mounting bracket, one of which is used to secure one of the second-ary cables.

Abstract: ABSTRACT         In the art of shaping sheets of glass and other deformable materials comprising engagement of said sheets while hot by a vacuum holder in a relatively hot atmosphere and removing the holder into a cooler atmosphere to cool the holder between successive shaping cycles, production of shaped sheets was limited by the time necessary for the holder to cool during its exposure to said cooler atmosphere to a temperature suitable for beginning a subsequent sheet shaping cycle.  The present invention lessens this necessary time by drawing cold air by suction from said cooler atmo-sphere between successive shaping cycles, thereby increasing the maximum production rate possible.

Abstract: ABSTRACT OF THE DISCLOSURE      Wiper comprising a matrix of nonwoven fibers having a basis weight generally in the range of from about 25 to 300 gsm and including a meltblown web having incorporated therein a staple fiber mixture including synthetic and cotton fibers.  The combination provides highly improved wiping properties as well as strength and absorbency for many industrial applications requiring wiping of oily and/or aqueous materials.  The wipers may be formed by a conventional meltblowing process involving extrusion of a thermoplastic polymer as filaments into airstreams which draw and attenuate the filaments into fine fibers having an average diameter of up to about 10 microns.  The staple fiber mixture of synthetic and cotton fibers may be added to the airstream, and the turbulence produced where the airstreams meet results in uniform integration of the staple fiber mixture into the meltblown web.  The matrix may contain up to 90% by weight of the synthetic and cotton fiber blend, which, itself, may contain up to about 90% by weight of the synthetic fibers.  The meltblown web may be formed from a wide variety of thermoplastic polymers including polyolefins, polyamides, polyesters, and the like.  The synthetic fiber component of the staple fiber mixture may also be formed from such synthetic thermoplastic materials as well as others including rayon, polyacetate, and the like.  Wipers produced in accordance with the invention have particularly improved oil absorption rate and clean wiping properties as demonstrated by residual testing and capillary suction curves.     1.            In particularly preferred embodiments, the staple component has a denier in the range of up to 6 denier for even further improved wiping properties.  The matrix is preferably bonded by a patterned application of heat and pressure or sonic energy providing for a percent surface area of bonding in the range of from about 5 to 30 with individual bonds in the range of from about 20 to to 200 bonds/in2 or line patterns either generally in a single direction or intersecting in the range of 2 to 15 lines per inch.   2.

Abstract: Disclosure 245-83-0090 ABSTRACT        A directional optical filter (41) is provided for a shadow mask color cathode ray tube (shadow mask CRT)  (47) having a plurality of display elements on its face (49).  Two sets of light absorbing planes are  arranged  at  approximately  90°  from  one  another  and  serve  to block  light  passing  therethrough  from  an  angle  greater  than a predetermined angle of viewing.   In order to  reduce moire patterns which  would  result  from  varying  coincidences  of  the  planes  with patterns of phosphor dots on the shadow mask CRT (47), filter sheets (43, 45) containing the light absorbing planes are rotated so that at least one set of light absorbing planes is misaligned with a set of closely-adjacent phosphor dots by approximately 15°.      Advantages  include  the  ability to  provide  a  parallel  light absorbing  plane  directional  optical  filter  in  association  with  a shadow mask  CRT and  an  ability to control  the  range  of preferred viewing angles to differing amounts substantially in the horizontal and vertical directions.

Abstract: DRUG, AND METHODS OF PREPARING AND USING IT          FOR TREATMENT OF TUMORS ABSTRACT      To  obtain   tumor-selective,  photosensitizing drugs useful in the localization of neoplastic tissue and treatment of abnormal neoplastic tissue such as tumors, one of two  methods is used.   In the first method, a hydrolyzed mixture of the products of reaction of hematoporphyrin with acetic acid and sulfuric acid is cycled through a microporous membrane system to exclude low molecular weight products.   In the second method, drugs are synthesized or derived from other pyrrole compounds.  The drugs:  (1)   include two covalently bound groups, each with four rings, some of which are pyrroles  such  as  phlorins,  porphyrins,  chlorins, substituted  pyrroles,   substituted  chlorins or substituted phlorins, each group being arranged in a ring structure,  connected covalently to another  group and have a triplet energy state above 37.5 kilocalories per mole; (2) are soluble in water, forming an aggregate of over 10,000 molecular weight in water and have an affinity for each other compared to  serum protein such that 10 to 100 per cent remain self aggregated in serum serum protein;  and (3) are lipophyllic and able to disaggregate and attach to cell plasma,  nuclear membrane, mitochondria, lysosomes and tissue.  The drug obtained by the first method has an empirical formula of approximately C68H70N8O11 or C68H66N8O11Na4.  Neoplastic tissue retains the drug after it has cleared normal tissues and   illumination  results   in necrosis.            Moreover, other photosensitizing materials may be combined with a carrier that enters undesirable   and cells of the reticular endothelial system such as macrophages. These photosensitizing materials:  (1) must have a triplet energy state above 3.5 kilocalories per mole; (2) cannot be easily oxidized; and (3) not physically quench any required energy state.          Preferably, this photosensitizing material should be lipophlic.
