Abstract: Chemorheologically viscosity tailored matrix resin formulation for use in forming prepregs and filament wound composite articles and having a specified viscosity profile comprising a curable matrix resin and an effective amount of a reactive resin curing agent reactive at room temperature and a latent resin curing agent substantially non-reactive at room temperature but activated upon heating or radiation such that the matrix resin formulation is adapted upon formulation to have a viscosity sufficiently low to enable the matrix resin to impregnate a filament or fiber at room temperature without the necessity for the application of heat or solvent and which, upon standing at room temperature after impregnation into the fiber or filament to form a prepreg composition, rises in viscosity to a viscosity level sufficiently high to prevent substantially any bleed of the matrix resin from winding tension upon spooling of the prepreg yet of sufficiently low viscosity to allow the prepreg to tack and drape in order to nestle and set during winding of a filament wound composite article from said prepreg after room temperature storage of the spooled prepreg material, and which matrix resin in the prepreg experiences a reduction in viscosity upon heating the prepreg composition, to a viscosity minimum sufficiently low to allow the matrix resin in the heated prepreg to flow and substantially eliminate formation of voids in the winding of a composite article from said prepreg yet not so low as to permit bleeding of the matrix resin from the prepreg and with the continued application of heat to the filament wound composite article to permit the matrix resin in the filament wound composite article to cure to a hardened or gelled state.

Abstract: ABSTRACT OF THE DISCLOSURE.    For automating the placement or removal of printing plates on plate cylinders (16, 17) of rotary printing machines, particularly web printing machines, an application head (11) is secured to a multiple linked roboter arm (2), slidable vertically along a guide post (1).   The roboter arm can be pivoted about the axis of the guide post, moved vertically thereabout, and includes a plurality of joints (3, 4, 5, 6) which connect roboter arm link elements (7, 8, 9, 10).  The positioning head (11) is located at the roboter arm element (10) most remote from the guide post.   The guide post is positioned between the axes of rotation of printing cylinders of adjacent printing stations, axially removed from the path of the web between the printing stations, so that interference with the web is effectively avoided.

Title: Actuator mechanism for pump sealing apparatus
Inventor: SIDELKO JOHN E
IPC: F04D29/14
Filed: 1991-03-07
Abstract: Abstract of the Disclosure A centrifugal pump of the hydraulic sealing type has a novel and improved sealing apparatus for establishing a hydraulic seal and limiting the flow of liquid from a pump casing into a reservoir or seal housing at one end of the pump casing, and a valve assembly in the seal housing hoes valve member normally urged into engagement with the seal housing to isolate liquid in the seal housing from the casing by washer-like spring elements.  When the pump is activated and brought up to speed, centrifugal force-responsive pivot members will impart sufficient opening pressure to overcome the resistance of the spring members when the pump approaches operating speed to move the valve member away from sealed engagement with the seal housing; and when the speed is reduced below the operating speed level the spring elements will rapidly undergo deflection to cause the valve member to return to a closed position.

IPC: G01T1/164

Abstract: TRANSMISSION/EMISSION REGISTERED IMAGE (TERI) COMPUTED TOMOGRAPHY SCANNERS     ABSTRACT AND SUMMARY OF INVENTION Reconstructed SPECT (Single Photon Emission Computed Tomography) images describe the intensity and location of sources of emitted photons in an attenu-ating medium, whereas transmission computed tomography (TCT) seeks to describe the distribution of different attenuation values within the attenuating medium.  The photons  emitted  by  inhaled,  ingested  or  injected radionuclide sources in the body are attenuated by the amount and density of the attenuating material along a line between any emission source and the detector.  The major problem in precise reconstruction of the SPECT image requires both the calculation of unknown activity in each part of the cross section as well as calcu-lation of the unknown attenuation coefficients.   The latter problem has been very poorly treated and is essentially unsolved by current methods which either make  the  (entirely incorrect)  assumption of uniform gamma ray attenuation for all parts of the body or which grossly attempt to register CT images obtained by a  different scanning device with different  scanning geometry  (and possibly different photon energy)  for attenuation correction of a SPECT image.  The present invention  defines  a  system,  a  method,  and  several families  of  apparatus  which  make  possible   the 1-1a acquisition of transmission and emission data from the same scanner.  There has, until the present invention, been no simple, safe and reliable method of creating transmission and emission images in exact registry on a multihead SPECT scanner.
