Covers are mounted so as to cooperatively close and seal the mouth or opening into conventional backhoe and clam-shell excavating buckets with the covers being positioned or positionable so as to engage the buckets after the buckets have been operated or manipulated to excavate earthen material or debris to thoroughly enclose such materials within the buckets until such time as the material is deposited into an appropriate receptacle or deposit site.

A floatable heavy duty hose assembly for conveying fluid entrained materials during dredging and related operations which includes a flexible cylindrical conduit which is reinforced at spaced intervals and wherein a plurality of floats are mounted in surrounding relationship with the conduit at the areas of reinforcement to thereby provide evenly distributed areas of flotation intermediate spaced areas of flexibility with the overall structure permitting the hose assembly to be handled and maneu...

Coupler assemblies for permitting the selective connection of two or more barges or other water borne floating vessels or structures wherein one or more pairs of vertically spaced coupler boxes are united in fluid tight communication with one another along one or more side walls of such vessels or structures in such a manner as to be open through the side walls, decks and bottom walls thereof and wherein upper and lower opposing coupler boxes of adjacent vessels or structures are united by upper...

An adjustable stirrup leather and a saddle including such a stirrup leather for suspending a stirrup relative to a saddle seat wherein a spring element is provided within the stirrup leather to provide a torsional force to properly align the stirrup for a rider's foot when the saddle is placed on a mount. In a preferred embodiment the spring element is vertically adjustable depending upon an adjusted length of the stirrup leather.

An auxiliary step for a stirrup associated with a saddle wherein the auxiliary step is mounted so as to be pivotable from a first position generally adjacent to the stirrup to a second position spaced below the stirrup to thereby assist a rider in mounting the saddle. In a preferred embodiment, the step is positively urged to the first or raised position adjacent to the stirrup when not being used to assist the rider in mounting.

A dredging apparatus for dredging waterways containing sediment includes a hood having a passage for water and sediment to enter the hood under the influence of a submersible dredge pump apparatus. The dredge pump apparatus includes an inlet line having an inlet opening positioned in the passage of the hood, and an outlet line which communicates with the inlet line and extends exteriorly to a spoil collection area. A dredge pump draws water and sediment from within the passage into the inlet ope...

An assist step for a stirrup associated with a saddle wherein the step is secured to or formed integrally with an outer side element of the stirrup which is pivotally mounted at a base of the stirrup such that when pivoted downwardly relative to the base, the step provides a platform for assisting a rider in mounting a saddle. The outer side element also functions as a safety breakaway portion for the stirrup to permit release of a rider's foot in the event a rider falls from the saddle.

The present invention relates to a process for the coating of objects made of valve metals or their alloys with a thin barrier layer consisting of the metal and an oxide ceramic layer provided thereon whose surface has been coated with fluoropolymers, characterized in that the fluoropolymers are introduced into the capillary system of the oxide ceramic layer in the form of a solution by vacuum impregnation, followed by removing the non-wetting portions of the solution and drying.

A directional thermal neutron detector for detecting thermal neutrons and determining the direction of the thermal neutron source. The directional detector includes an array of individual thermal neutron detector modules, each of which comprises front and back planar silicon detectors having a gadolinium foil sandwiched therebetween. The array comprises a plurality of individual detector modules which are angularly displaced with respect to each other. The direction of the thermal neutron source...

The degradation of harmful substances in water by compounds, such as hydrogen peroxide, which form hydroxyl radicals under UV irradiation in continuous reactors is improved when the irradiation is carried out in a reactor with a specific reactor volume of at least 10 liters per kW of the UV radiator or radiators, and if the amount of water to be treated is 0.25 to 25 times the amount of the intrinsic volume of the reactor flows through the reactor per hour. It is particularly preferred that the ...
