A bridge construction is disclosed in which the ends of a bridge deck are supported by an abutment comprising a mass of internally stabilized earth. A plurality of elongate reinforcing members are arranged in vertically spaced horizontal layers. Within each layer the members are spaced apart laterally and some of the members extend at right angles to other members to form a lattice. Particulate material is placed and compacted into a contiguous aggregate which fills the vertical array of horizon...

A container and closure cap therefor which forms a package unit, with the container having an open top, a continuous sinuous surface adjacent the open top, the sinuous surface including rounded projections merging into adjacent rounded recesses, a closure cap for the container, the cap having a skirt and an open bottom with a continuous sinuous surface on the skirt, the last mentioned sinuous surface shaped complementary to the container sinuous surface so that the sinuous surface of the closure...

A radiation-sensitive element comprises a support having thereon a composition comprising a depolymerizable polymer, such as a polymer of an aromatic 1,2-dialdehyde, and may also contain a radiation-sensitive substance or combination of substances, binder and/or a color-forming substance or combination of substances. A negative-working radiation-sensitive process comprises exposing a radiation-sensitive element to radiation, following which the element is heated in order to accelerate the depoly...

S-nitrosohemoglobin can liberate NO by transfer to a low molecular weight thiol in the circulatory system, allowing the delivery of NO to the tissues. The effect of administering isolated S-nitrosohemoglobin and low molecular weight thiol to a mammal is to increase delivery of oxygen and NO.

Tetrazocines, prepared by reacting hexamethylene tetramine with a monocarboxylic acid anhydride. The compounds have utility as dispersants, suspending agents and blending agents.

A one-piece paperboard blank for erection into a display carton capable of supporting an article, such as an inflatable basketball, football, etc., in a manner that opposed surfaces of the article are exposed includes solid top, bottom, and side panels, while the back panel is defined by specially curved portions articulated to the top and bottom panels, and lock panels articulated to the side panels, with the lock panels and the curved panels being interconnected by intermediate articulated web...

A drumstick having a tip of synthetic material, the tip having a plurality of substantially circumferential grooves. A drumstick having a handle portion with a cylindrical shaft and a striking tip extending from one end of the shaft, the striking tip having a substantially spherical conformal cap of synthetic material, the cap having a plurality of substantially circumferential grooves that are disposed in space substantially parallel to one another and substantially equidistantly spaced. The ti...

This invention relates generally to articles of glass-ceramic, including glass-ceramic components of articles, and to processes for manufacturing these glass-ceramic articles. Specifically, a glass article is formed, the surface layer of the article is ion exchanged to add lithium, the surface layer is crystallized, and finally the whole article is bulk crystallized.

This invention relates generally to articles of glass-ceramic, including glass-ceramic components of articles, and to processes for manufacturing these glass-ceramic articles. Specifically, a glass article is formed, the surface layer is crystallized to form a skeleton, and finally the whole glass article is bulk crystallized.

This invention relates generally to articles of glass-ceramic, including glass components of articles, and to processes for manufacturing these glass-ceramic articles. Specifically, a glass article is crystallized in bulk, ion exchanged to add lithium to the surface layer, and heated to crystallize the surface layer where the coefficient of expansion of the surface is less than that of the main body.
