Title: Method for producing low sheet gloss coated paper
Inventor: LEE DO I
IPC: D21H19/10
Filed: 1987-04-27
Granted: 1992-04-21
Abstract: ABSTRACT     This invention relates to an improvement in the production of low sheet gloss coated papers which comprises using as the synthetic polymer latex binder for the aqueous coating composition employed to coat the papers, a carboxylated latex which substantially swells during the preparation of the aqueous coating composition and subsequently shrinks during the drying of the coated paper, whereby a microscopic surface roughness is obtained to yield a low sheet gloss coated paper while retaining high ink gloss without detrimental effect on ink gloss, or the printing characteristics of the coated paper.  Carboxylated latexes and their methods of preparation are generally taught in the art,  The carboxylation is introduced by utilizing as one of the comonomers in the preparation of tha latex a vinyl acid, such as acrylic acid, 34,505 F     methacrylic acid, itaconic acid, fumaric acid, and maleic acid.  The carboxylated latexes suitable for use in this invention are those which contain at least 6 parts of a vinyl acid monomer per 100 parts of total monomers.  Using these carboxylated latexes as the binder for the aqueous coating composition employed to coat papers produces low sheet gloss coated papers to be prepared without the use of large pigment particles and/or specialized supercalendering techniques.     34,505-F

Abstract: A pipe bolt having a central bore is inserted into a hole formed in an underground excavation.  A high density grout is injected into the central bore of the pipe bolt to cause the high density grout to travel through the bore, out of the pipe bolt and past the sides of the bolt filling the space between the bolt and the hole.  The high density grout allows for improved bonding strength concomitant with reduced porosity.

Title: Method for manufacturing an optical probe
Inventor: GUENTHER MARTIN
IPC: A61B5/00
Filed: 1989-04-07
Granted: 1994-07-19
Abstract: ABSTRACT Optical probes for the invasive measurement of blood parameters consist of at least one sensor (6, 7, 27), each of these sensors (6, 7,27) having a diffusion zone with a selective membrane (20, 24, 29). The sensor or the sensors (6, 7, 27) are surrounded by a stabilizing sheath (5). This sheath (5) is to be fastened on sensor(s) (6, 7, 27) by a glue (17). A silicone glue provides the feature that gas molecules can diffuse through it; therefore, blood gas sensors such as PO2 sensors or pCO2 sensors may be completely embedded in said glue. If a pH sensor (6) is used, it must be placed in the top position of the horizontally lying sheath (5) during manufacturing. The silicone glue then does not cover the diffusion zone of the pH sensor (6) com-pletely. Further, silicone glue provides additional elasticity which improves sensor characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE A noise and vibration damper for a shift lever assembly in a manually operable vehicle transmission is disclosed.  The damper includes a hollow cylindrical housing having upper and lower pairs of aligned, transversely extending apertures.  The upper end of a lower shift lever member extends upwardly into housing, while the lower end of an upper shift lever member extends downwardly into the housing.  A transversely extending pin extends through apertures formed in the ends of each of the shift lever members and through their respective pair of apertures to secure the shift lever members to the housing. The ends of the pins are supported within the apertures by nylon bushings.  The ends of the upper and lower shift lever members are spaced apart from one another and from the damper housing by a hollow cylindrical sleeve of vibration dampening material, such as polyurethane.  The polyurethane is injected into the housing and molded about the ends of the shift lever members so as to acoustically isolate them from one another.  A collar is provided about both the upper and lower ends of the damper housing to provide positive stops for the shift lever members when they are moved.
