A satellite dispenser and method of using same are disclosed. In various embodiments, a satellite dispenser as disclosed herein includes a dispenser body defining an interior cavity to accommodate a payload; and a plurality of externally adjustable restraints positioned within the interior cavity and configured to be extended further into the interior cavity by actuation of a manual interface external to the interior cavity.

Disclosed is a self-lubricating composite friction part (1) that can be subjected, during operation, to temperatures that are at least equal to 250 C. The part includes, along the friction surface (2), a single layer of a material consisting of weft and warp yarns made of polytetrafluoroethylene, the material being impregnated with a thermostable resin having a glass transition temperature that is at least equal to 250 C. It is applied to a reinforcing layer (3).

A bearing having an electrically conductive sleeve and a self-lubricating liner wherein the electrically conductive sleeve comprises a first portion and a second portion, the first portion and the second portion having respectively an inner surface and an outer surface; the self-lubricating liner extends over the inner surface of the first portion of the electrically conductive sleeve to define a first tubular volume, the first tubular volume having a first diameter and a first longitudinal axis; and the inner surface of the second portion of the electrically conductive sleeve defines a second tubular volume, the second tubular volume having the same diameter and the same longitudinal axis as the first tubular volume.

First and second bearing cage halves each having an annular base body and a plurality of pins extending from the base body and a plurality of pin receptacles, the first and second cage haves forming a bearing cage when the pins are received into the pin receptacles. A body of sacrificial material is located on the pins and/or in the pin receptacles which body is configured to be melted ultrasonically to join the first cage half to the second cage half and form the bearing cage.

A flexible composite driveshaft is formed by modifying the shape of a preliminary composite driveshaft. A fiber tape is applied to a temporary mandrel using automated fiber placement to form a preliminary composite driveshaft having a flexible shaft element with an initial geometry. The temporary mandrel from the preliminary composite driveshaft is removed and the initial geometry of the flexible shaft element is modified to form the flexible composite driveshaft having a flexible shaft element with a final geometry.

An annular ring having a contact portion, a raceway and a squirrel-type cage secured to the contact portion. The contact portion is formed from a first metal material, and the squirrel cage is formed from a second composite-type material including a matrix in which reinforcing fibres are embedded, the pierced portion of the squirrel cage being attached to an outer surface of the contact portion. Also, a bearing assembly with rolling elements having an outer ring, an inner ring coaxial with the outer ring, and a plurality of rolling elements housed between the raceway of the contact portion of the outer ring and a raceway of the inner ring.

A connection element providing a first ring and a second ring, the two rings rotating relative to one another about a central axis, the first ring having a contact portion with a contact surface interacting with the second ring for the relative rotation, and a fastening portion configured to be rigidly secured to a support. The contact portion is made of a first material and the fastening portion is made of a second material, different to the first material, the first material having a hardness strictly greater than that of the second material, and the second material having a structural fatigue strength strictly greater than that of the first material.

A sliding contact surface-forming material, and method of making the material are disclosed, the material having minimal swelling and excellent friction-proof and wear-proof characteristics when used in moist environments such as in water, and improved in the friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, particularly under oscillation conditions for testing journal. The material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, as each of the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyester fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.

An orifice plate includes a wear-resistant inner diameter surface, an outer diameter surface, a first side surface extending between the wear-resistant inner diameter surface and the outer diameter surface, and a second side surface extending between the wear-resistant inner diameter surface and the outer diameter surface, the second side surface disposed opposite the orifice plate from the first side surface. The orifice plate may comprise a body portion comprising a first material. The wear-resistant inner diameter surface may comprise a second, wear-resistant material.

The invention relates to a pivot connection type assembly comprising a shaft and first and second connection parts, each receiving the shaft so as to enable them to pivot relative to each other, the first connection part being arranged axially between a first end of the shaft and a radial plane, while the second connection part is arranged axially between said radial plane and the other end of the shaft. The shaft is hollow and includes an inside section that presents a radial dimension at least in a first axial plane and over a first segment of the shaft extending axially between the first end and the radial plane, which radial dimension varies, decreasing on axially approaching the radial plane. The assembly includes a ring interposed radially between the shaft and a bore of the first connection part, and presenting radial thickness that varies.
