Abstract: A hydraulic pump or motor includes a mounting flange that is disposed at the first end of the housing. The mounting flange defines a pair of bolt receiving slots that are disposed along the X-axis on either side of the shaft. The pair of bolt receiving slots each define a radius center that are spaced away from each other a X dimension, and a pilot projection extends longitudinally away from the mounting flange, defining a pilot projection diameter. A ratio of the X dimension to the pilot projection diameter ranges from 1.1 to 1.5.

Abstract: A female mounting member is configured to mate with a hydraulic pump or fan. The member includes a body that defines a projection receiving cavity defining a cavity diameter, and a first threaded hole defining a first threaded hole diameter. A ratio of the cavity diameter to the first threaded hole diameter ranges from 8.0 to 8.15.

Abstract: A casing cover for enclosing a casing in a jet engine is disclosed. The casing cover includes two coaxial shells arranged one inside the other and radial envelopes which connect the two coaxial shells. Radial arms of the casing extend inside the radial envelopes. The cover is fastened at its downstream end to a first element of the casing and axially abuts at its upstream end on a second element of the casing. In a free state, an axial dimension of the cover of less than the axial distance of the casing between the point where the first element of the casing is fastened to the downstream end of the cover and the point where the second element of the casing axially abuts the upstream end of the cover such that the cover is tensioned axially when it is mounted on and fastened to the casing.

Abstract: Casing cover (10) in a jet engine, comprising two coaxial shells (36, 38) arranged one inside the other and joined fixedly by radial envelopes (40) inside which extend radial arms (26) of the casing, the cover being fastened at its downstream end to an element of the casing and bearing axially at its upstream end on another element of the casing, and the cover having, in the free state, an axial dimension (D) of less than the axial distance (L) between the points where its downstream end is fastened to the casing and the points where its upstream end bears axially on the casing, and being tensioned axially when it is mounted on and fastened to the casing.

Abstract: The invention concerns a device for removing dust from nuclear fuel pellets.The object of the invention is to embody a device able to simply and effectively remove dust from pellets coated with dust, including non-electrically charged dust.This aim is obtained by using a device including a dedusting tube (1) inside which said pellets (35) circulate, said tube (1) being provided at its inlet extremity (2) with a gas injection orifice, an opening for introducing the pellets to be dedusted and means to create a laminar flow of dedusting gas around the pellets circulating in said tube, said tube (1) being further provided at its outlet extremity (4) with a gas and dust suction opening and an opening for recovering the dedusted pellets (35).

Abstract: The invention relates to a process for preparing pieces of solid electrolyte based on stabilized zircon having an improved conductivity due to the addition of Al.sub.2 O.sub.3. According to the process, an alcoholic solution is prepared of a salt of zirconium, a salt of a metal stabilizing zircon such as yttrium and a salt of aluminium; from this solution is formed a coprecipitate of hydroxide of zirconium, hydroxide of said metal and hydroxide of aluminium; the precipitate is washed by means of a hydrophilic solvent to eliminate the traces of water, then is dried and calcined in air; a piece of solid electrolyte is then formed by compression and sintering from the powder obtained.The invention is applicable to the production of solid electrolytes for cell for electrolysis of water vapor or for fuel cell.
