摘要:
A nozzle in which an airfoil includes a pressure surface and a suction surface that join at substantially opposing chordal ends of the airfoil to form a leading edge of the airfoil and a trailing edge of the airfoil. A trailing edge passage is defined through the airfoil through which coolant flows. The trailing edge passage is proximate to the trailing edge of the airfoil and has a contoured shape that conforms to that of the trailing edge.

The present invention relates to sealants for skin and other tissues. The sealants include an electroprocessed material. The sealants may contain more than one electroprocessed materials and may contain additional substances. The invention further relates to methods of making and using such sealants.

A drill-pin implant includes a cannulated body having an interior surface and an exterior surface each extend between a first end and an opposing second end. The interior surface bounds a guide aperature through the body. The first end of the body is configured to penetrate into bone by cutting away the bone as the body is rotated. One or more external threads redially outwardly project from the exterior surface of the body. The external threads are configured to engage bone so as to secure the body to the bone.

Compositions for electrodepositing silver, comprising a soluble silver compound, a non-cyanide electrolyte and selected organic phosphonate compounds, are described. These are stable for prolonged periods and are capable of depositing silver at relatively high rates without the need for soluble silver electrodes or cyanide replenishment to the bath, in contrast to conventional procedures.

A bone alignment implant includes a first bone fastener with a first bone engager that is adapted for fixation into the metaphyseal bone and a second bone fastener with a second bone engager that is adapted for fixation into the diaphyseal bone. A link connecting the two fasteners spans across the physis. Alternatively, the bone alignment implant is adapted for fixation into the diaphyseal sections of two adjoining vertebral bodies. These implants act as a flexible tethers between the metaphyseal and the diaphyseal sections of bone during bone growth. These implants are designed to adjust and deform during the bone realignment process. When placed on the convex side of the deformity, the implant allows the bone on the concave side of the deformity to grow. During the growth process the bone is then realigned. A similar procedure is used to correct torsional deformities.

The invention relates to a berley dispenser which can hold large pieces of berley. Under the action of wave movement, the berley dispenser chops the berley into smaller pieces which are then dispersed through a series of apertures.
摘要:
Disclosed are compositions of nonionic siloxane alkoxylates with aminopolyalkyleneoxide surfactants which are useful in treating plants, for instance as adjuvants for pesticides including in particular herbicides. These compositions overcome the antagonism associated with nonionic trisiloxane alkoxylates on pesticide uptake in plants.
摘要:
Disclosed is a palladium electroplating bath and a method of plating therewith. The bath contains palladium as the palladosammine chloride and a phosphonic compound which is an alkylene diamine phosphonate derivative. The bath may be employed to plate palladium or its alloys. In a preferred embodiment, a pure palladium deposit may be obtained which exhibits very low porosity even after subsequent cold forming of the article on which it is deposited.
摘要:
The present invention relates to a method for consecutively producing at least two different polyethylene resins in one slurry loop reactor, comprising producing a first polyethylene resin in the presence of a Ziegler-Natta and/or a Chromium catalyst, and consecutively producing a second polyethylene resin in the presence of a metallocene catalyst, characterized in that the ratio of the melt flow index of the first produced polyethylene resin to the melt flow index of the second produced polyethylene resin is at least 0.3.
摘要:
A clamping device particularly for use in the preliminary stages of the erection of roof trusses, the clamping device comprising a first attachment means (11) to enable the device to be securely and releasably attached to one truss, a second attachment means (20) to enable the device to be attached to an adjacent device or a truss, and means (13) to enable the length between the first attachment means and the second attachment means to be varied.
