Abstract: This invention provides E.M.I. gaskets for electrically shielding and environmentally sealing the space between two surfaces which comprises a metallic electrically conductive deformable structure adapted for forming electrical contact with said surfaces and/or providing electrical shielding in the space between said surfaces; and a gel material for sealing the space between said surfaces having a cone penetration value of about 100 to about 350 (10<-><1>mm) and an ultimate elongation of at least 200% and being present in sufficient amount and positioned to provide environmental seal between said surfaces and to provide environmental protection for said metallic structure. The gel may encapsulate the entire metallic structure so that portions of the metallic structure pierces through the gel when the gasket is installed to make electrical contact. Alternatively portions of the metallic structure may extend beyond the surface of the gel and the gel deforms to cover exposed portions of the metallic structure when the gasket is installed. The gasket of this invention provides moisture seal and is resistant to corrosion.

Abstract: A variable gain analog to digital compression encoder apparatus and method is operational for 'on the fly' gain adjustments without introducing significant distortion or noise in telephone conversation. An incoming analog signal (9) is fixed gain (11) reproduced as a first stabilized mid-operating point analog signal (41). A second stabilized mid-operating point analog signal (42) is produced in inverse proportion to the first stabilized mid-operating point analog signal, in response to a signal (43) tapped along a signal division of a difference between the first and second signals. The second signal is compression encoded (13) at a predetermined rate to produce pulse code modulated signal samples (25). The tap may be varied (44) to change the encoding gain, at any time, in accordance with operating requirements of a telephone apparatus.

Abstract: A surgically implantable shunt system (20), including a flow control valve (24) and an antechamber (22), is provided for controlling the release of entrapped body fluids. The flow control valve (24) includes a pair of molded plastic bases (42, 44) situated, respectively, adjacent to an inlet (74) and an outlet (76) of the valve (24), which bases (42, 44) are situated within a flexible encasement (46). Each base (42, 44) includes an outer housing (48, 56), a valve membrane carrier (50, 58) positioned within the housing (48, 56), and a flow control member (52, 60). The flow control members (52, 60) each include a rigid nail-like central support and a separate flexible resilient membrane (70) positioned on the central support. The first flow control member (52) is capable of selectively occluding the valve inlet (74), but is normally spaced from its base (42) to permit free fluid flow through the inlet (74). The second flow control member (60) is generally arch-shaped and resiliently biased to contact its respective base (44) generally along the outer edge of the membrane (70) in a manner permitting only controlled one-way flow through the valve (24). The antechamber (22) permits injection of medication into the shunt (20) between a proximal catheter and the distal flow control valve (24), and pumping of the medication in either direction. Additionally, a method for assembling the shunt system (20) in a quick and economical manner is provided, which utilizes tapered grommets (96) to anchor components in place prior to adhesively securing tubing (28, 30) to the flexible encasement (46).

This surface structure, the roughness height Ra of which lies in the range of just a few  mu m, is impressed in the material to create fine surface grooves or ribs by corresponding shaping of the contour of the die orifice at the extruder output or, for example, in a band press by the structure of a fabric running along with it. This undersurface is preferably produced in ski production in the form of an undersurface prefabricate on which the undersides of the steel edges of the ski are flush with the upper edges of the ribs of the said undersurface. <IMAGE>

Abstract: Novel lubricant compositions comprising polyalpha-olefins are disclosed having high viscosity indices with low pour point. The compositions are characterized by a uniform molecular structure with low branch ratios. The invention describes a liquid lubricant composition comprising C30-C1300 hydrocarbons, said composition having a branch ratio of less than 0.19, weight average molecular weight between 300 and 45,000, number average molecular weight between 300 and 18,000, molecular weight distribution between 1 and 5 and pour point below -15 °C. 1-decene trimer comprising 9-methyl, 11-octylheneicosane and 11-octyldocosane is disclosed. The lubricant compositions are produced by contacting said alpha olefin with a supported solid reduced Group VIB (e.g., chromium) catalyst under oligomerization conditions at a temperature of about 90 to 250 °C to produce liquid lubricant hydrocarbon. The hydrogenated lubricant range hydrocarbon product has viscosity index of about 130 to 280 and a viscosity up to about 750 mm2/s(cs). The process is particularly useful where the starting alpha olefin consists essentially of olefinic hydrocarbon having 8 to 14 carbon atoms or mixtures thereof; wherein the process conditions include reaction temperature of about 100 to 180 °C; and wherein the support catalyst includes porous inert silica.
