Abstract: 12,122 METHOD FOR PREPARATION OF CATIONIC CELLULOSE                     ABSTRACT OF THE DISCLOSURE The invention is a fibrous, cationic cellulose pulp product and the method for preparing it. A water suspension of cellulosic fiber is treated under alkaline conditions with a condensate of epichlorohydrin and dimethylamine. Up to 30 molar percent of the DMA may be replaced by a crosslinking agent such as ammonia or a lower aliphatic diamine. The process may be carried out at room or elevated temperatures. It is practical to add the condensate at one of the later alkaline stages of a bleaching process; e.g., an alkaline extraction or peroxide stage. This is most preferably done later than any chlorination or hypochlorite stages. The product shows greatly improved retention of acid and other anionic dyes. It also shows superior retention of some pigments and latices without the need for other cationic aids. In some cases a small amount of alum appears to have a synergistic retention effect with the cationic pulp product when used with titanium dioxide and certain anionic latices.

Abstract: ABSTRACT OF THE DISCLOSURE          Method and apparatus for acoustic wave generation and transmission into a subsurface earth formation, particularly adapted for use in borehole shear wave logging.  A logging sonde adapted to be suspended in a borehole traversing a formation houses a source of acoustic waves.  The source simultaneously generates a plurality of acoustic waves propagating generally radially outward from locations within the sonde housing adjacent the vertical central axis thereof and will interfere to produce multipole acoustic waves in the formation.  Detector means within the housing spaced longitudinally from the source detect acoustic energy in the formation resulting from the generated waves.  In a preferred embodiment, the source includes a cross-shaped rod assembly comprised of two rods perpendicular to each other and joined at their mid-points through which the central axis passes.  The rods lie in a plane perpendicular to the central axis and are preferably each comprised of a different magnetostrictive material such that the strain constant of the rods differ in sign.  Ends of each rod have a respective acoustic radiator attached thereto facing radially outward.  Upon electrical excitation of the rods, they may be caused to vibrate along their respective longitudinal axes substantially 180° out of phase with respect to each other.          Vibration of the reflectors of the first and second rods, in response thereto, set up respective first and second pairs of acoustic waves also out of phase with respect to each other which propagate from the radiators into the formation, where they interfere to produce the desired quadrupole acoustic wave.

Abstract: ABSTRACT OF THE DISCLOSURE:            A telescopic umbrella has a slider movable on a stick and has a canopy which supports forks to be opened and closed by the slider and which are provided in a star-shaped arrangement around a crown.  The crown is fitted on the stick and around  the  slider.   In each case  a link parallelogram is actuated by a scissors lever drive for the control of the folding motion of peripheral canopy spokes. In order to enable the canopy supporting forks to be more stable in  their middle region,  which is  sensitive to deformation or rupture,  and in particular to make in more resistant to excessive strain by gusts of wind causing the canopy to turn inside out, a hinge, connecting the inner canopy strut to the control strut,  in the open position of the umbrella canopy,  lies adjacent to the diagonal of the link parallelogram and bears against the bottom edge of a supporting strut so that the link parallelogram appears as a flat triangular formation.  This triangular formation has an obtuse outer angle (?),  while the hinge of the link parallelogram,  connecting the supporting strut to a short arm of the peripheral canopy spoke, adopts from above about the same distance from the diagonal as the hinge connecting the inner canopy strut to the control strut adopts from below.

Abstract: ABSTRACT         A method and apparatus are disclosed for accurate insertion of a ventricular catheter through the cranial surface into the ventricular system of the human brain.  The method in-cludes providing an orifice through the human cranial surface, cutting and coagulating the dural membranes separating the cere-bral substances from the interior cranial surface, and inserting a flexible catheter rendered rigid by incorporation of an obdur-ator in its lumen, or central cavity, through the cranial ori-fice and the cerebral substances into a ventricle  of the brain.          The catheter defines its path of entry into the ventricular sys-tem through a guide assembly mounted on the exterior of the cranial surface.  The guide assembly is disposed to enable the catheter and incorporated obdurator to enter the cranial orifice and cerebral substances and hence the ventricular system at an angle of 90° in relation to an imaginary plane formed by a tan-gent to the cranial surface at the point of entry through the orifice.  The obdurator is removed from the catheter when the catheter and incorporated obdurator have penetrated the ventric-ular system.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for connecting a tubular element to an underwater wellhead.  A wellhead extension having a threaded lower end is threadably connected to an underwater wellhead.  A stinger connected to a lower end of a string of riser pipe is lowered into the wellhead extension until the riser pipe is sealably connected to the extension spool.  In the event of damage to the hanger threads, a housing is mounted on the lower end of a string of riser pipe or a wellhead extension.  A substantially tubular nut is threadably engaged with the housing and includes a set of downwardly-projecting lugs on the lower end of the nut.  On the lower portion of the housing, a set of slips and an annular seal are mounted.  The housing is lowered until the lugs are engaged with flow by ports in the wellhead hanger.  Rotation of the pipe effects longitudinal housing movement relative to the nut which sets the slips thereby joining the housing to the hanger, and energizes the seal between the wellhead and the housing.

A transparent elastic solid medium contains uniformly dispersed droplets of a very high vapour pressure detector liquid substantially immiscible with the elastic solid.  It has been found possible to form stable droplets having a sufficiently high degree of superheat for their vapourization to be sensitive to lightly ionizing radiation such as gamma rays and even to microwave radiation.  The droplets can be made stable to spontaneous vapourization, yet their explosive vapourization will be triggered by gamma or in some cases microwave radiation.  The solid medium will retain a record of each droplet vapourized, the number being proportional to the dose of radiation.  If desired the detector liquid vapours can be condensed or compressed into droplets again and the detector/dosimeter re-used.
