Abstract: A catheter consists of a torque transmitting portion which has rigidity sufficient for torque transmission and a flexible portion made of a material having a glass transition temperature for giving rigidity before insertion and flexibility after insertion.  The torque transmitting portion maintains torque transmitting ability before, during and after insertion.           The flexible portion maintains appropriate rigidity before and during insertion, which enables easy insertion, and gains flexibility after insertion by the body heat, which avoids hurting of the vulnerable insertion walls.  Further, the torque transmitting portion may have a structure wherein a reinforcement of a coil or a braid of linear metal wires, specifically flat rectangular wires, is attached thereto to afford torque transmitting ability.  Catheters having various functions and structures can be easily manufactured by extrusion-molding, or the like.

Title: Method of treating a fibrous cellulosic web and liquids for use therein
Inventor: HOLMSTEDT JAN W
IPC: D06M11/79
Filed: 1991-06-14
Abstract: Abstract The invention provides a liquid for impregnating a fibrous cellulosic web , the liquid comprising a mixture of at least one alkali metal silicate solution, a plastics dispersion and a surfactant, characterised in that the liquid comprises; 50-85% by volume of sodium silicate solution; 1-36% by volume of potassium silicate solution; substantially 10% by volume of a plastics dispersion; substantially 2% by volume of a 10% surfactant; and substantially 2% by volume of silicon dioxide chloride in a 50% by volume water solution.     The invention also provides a method of treating a fibrous cellulosic web for producing sheets, tubes or other elements, comprising the step of fully immersing the fibrous cellulosic web in an impregnating liquid prior to formation of the fibrous cellulosic web into the sheets, tubes or other elements, characterised in that the impregnating liquid is as described above.     The fact that the fibrous cellulosic web passes through an impregnating liquid prior to being formed into sheets, tubes or other elements increases the rate of penetration into the material and therefore shortens the production time of fully impregnated materials.  The properties of the material are also enhanced sufficiently to enable elements suitable for use in the building industry to be made.

IPC: A61B3/032
Filed: 1990-11-21
Abstract: A method for diagnosing deficiencies in and expanding the size of a person's "Useful Field Of View" (UFOV").  The UFOV is determined by the eccentricity (in degrees of visual angle) at which peripheral targets (presented within an embedding context) can be localized 50% of the time while performing a concurrent visual task in central vision.  The method provides multiple blocks of trials, each block of trials consists of displaying a plurality of times before a subject's vision a set of four sequentially presented images having specific characteristics, and the specific characteristics of each block of trials is changed each time a new block of trials is displayed before the subject.  By changing the characteristics of each block of trials, a diagnosis can be made of the subject's vision by creating a subject database that contains the subject's indicated responses to each block of trials having specific characteristics and comparing the subject database to a normative diagnostic database in order to achieve a diagnosis.  The method also employs training programs to expand the size of the subject's UFOV.
