A method of making hollow cylindrical articles provides for preparing a blank through electroslag casting at a speed of 0.3 to 0.6 mm/sec., its surface hardening with a flow of plasma jet formed in a plasmatron at a current intensity of 220 to 320A, at a linear rotation speed of the blank of 3 to 10 mm/sec. and at a gap of 2 to 10 mm between the plasmatron and the blank, and its magnetoabrasive ma...

A partially-oxidized spent pulping liquor is produced which is added to unoxidized strong spent pulping liquor prior, during, or subsequent to concentration to form a novel partially-oxidized, concentrated, high total solids spent pulping liquor. This novel, partially-oxidized, concentrated spent liquor is capable of being combusted in a spent liquor recovery furnace without the addition of auxili...

Process for the oxidation of sulphur dyes or vat dyes. The oxidation bath contains hydrogen peroxide, a metal salt, preferably a copper salt, and an alkaline vanadate.

A roadway barrier section (10) includes a duct (26) formed of two intersecting frusto-conical portions (32, 34) placed end-to-end so that the portions taper from the ends of the barrier toward the central portion (40) thereof. The duct (26) is formed using two tapering mold plugs (76, 78) that are preferably frusto-conical. The mold plugs (76, 78) are placed in a concrete form so that the lower ed...

Improvements to instantaneous connections for smooth and bare pipes comprising a hollow body with a bore equal to the fluid passage and an inner housing of appropriate shapes wherein are arranged a sealing means and a pipe holding means, the housing being limited by a bearing and a stopping means. The housing which has at least two successive bores (1a-1b) contains a sealing member (2) and a holdi...

A gun barrel is produced by vacuum plasma spray depositing an inner layer of a refractory metal as a gun barrel liner on a mandrel, followed by deposit of successive layers of dense gun barrel jacket material to build up a structure from the inside out. The outermost layer can include attachment means for fixing the barrel into a gun mechanism.

An ice detector of the vibrating element type comprises a tube that vibrates along its longitudinal axis, and is driven by an excitation coil at the natural frequency of the tube is sealed by a diaphragm which has a surface exposed to an air stream in which icing is to be sensed. The exposed diaphragm surface is deflectable during vibration of the tube at a flexible support portion of the diaphrag...

A transducer assembly includes first and second stators which are axially aligned with, and bear upon opposite sides of a proof mass. The stators and proof mass are clamped together by means of a sleeve having a side portion with spaced apart upper and lower flanges extending therefrom. The flanges bear against receiving surfaces on the stators with the sleeve under elastic deformation such that a...

A transducer assembly includes first and second stators which are axially aligned with, and bear upon opposite sides of a proof mass. The stators and proof mass are clamped together by means of a sleeve having a side portion with upper and lower flanges projecting therefrom.

A reagent and method for in vitro determination of the eye irritating properties of individual compounds and/or mixtures is disclosed. The material to be assessed is combined with the reagent which provides a response, for example, the production of a precipitate, which is proportional to the deleterious response elicited by the material in the human eye.

A radiometer (100) uses the fringe pattern of an interferometer (110) to scan a scene to produce a time record from which a high-resolution radio frequency, or other radiation, distribution of the scene can be reconstructed. A matched filter (120), or other means, transforms the time record according to a function of a signature of the determinable scanning motion relative to the fringe pattern. F...
