International Classification:

H01J 29/02

US Classification:

313414, 313409, 313383, 313389, 313446

Abstract:

A multi-beam electron gun provides a plurality N of cathode assemblies comprising a cathode, anode, and focus electrode, each cathode assembly having a local cathode axis and also a central cathode point defined by the intersection of the local cathode axis with the emitting surface of the cathode. Each cathode is arranged with its central point positioned in a plane orthogonal to a device central axis, with each cathode central point an equal distance from the device axis and with an included angle of 360/N between each cathode central point. The local axis of each cathode has a cathode divergence angle with respect to the central axis which is set such that the diverging magnetic field from a solenoidal coil is less than 5 degrees with respect to the projection of the local cathode axis onto a cathode reference plane formed by the device axis and the central cathode point, and the local axis of each cathode is also set such that the angle formed between the cathode reference plane and the local cathode axis results in minimum spiraling in the path of the electron beams in a homogenous magnetic field region of the solenoidal field generator.

Assignee:

N.V. Raychem S.A. - Kessel

International Classification:

H01B 1300

US Classification:

156 56

Abstract:

The present invention provides a method of re-entering and reclosing a cable splice case enclosing a splice between first and second cables and comprising a wrap-around sleeve and a closure channel, the sleeve having opposing longitudinal edge portions, each bearing a rail, the edge portions having been brought together around the splice such that the rails are adjacent one another and the closure channel being positioned over the adjacent rails, which method comprises: (a) removing a portion of the sleeve from the splice, leaving an end portion of the sleeve attached to the first cable; (b) removing a portion of the channel from the rails of the remaining portion; (c) positioning over the rails of the end portion at a position where the portion of channel has been removed a hot-melt adhesive plug, the plug having a recess for receipt of the rails; (d) positioning a heat-shrinkable reclosure sleeve around the splice, the reclosure sleeve extending from the adhesive plug at the end portion; and (e) heating to cause the reclosure sleeve to shrink into engagement with the end portion and to cause the plug to soften and form a seal.

Assignee:

N.V. Raychem S.A. - Kessel-lo

International Classification:

B32B 3126

US Classification:

156 85

Abstract:

A method of forming a branch-off seal between a heat-shrinkable sleeve and at least two substrates, which comprises the steps of: (a) positioning the substrates within the heat-shrinkable sleeve; (b) forming at least two heat-shrinkable terminal conduits by positioning a clip having at least three elongate legs over the outer surface of the heat-shrinkable sleeve at an open end thereof, wherein at least two of said legs are positioned externally of the sleeve, the substrates are within the terminal conduits and at least one of said legs is positioned internally of the sleeve, and (c) while the clip remains on the outer surface of the heat-shrinkable sleeve, applying heat so as to effect shrinkage of the sleeve and to form the desired seal; in which the leg positioned internally has a coating of heat-softenable sealing material that extends beyond its distal end, the extension being such that at least a portion of extending material does not flow significantly during step (c).

International Classification:

H02G 1508

US Classification:

174 88R

Abstract:

A method of forming a branch-off seal between a heat-shrinkable sleeve and at least two spaced-apart elongate substrates, which comprises the steps of: (a) positioning the substrates within the heat-shrinkable sleeve; (b) positioning between the substrates and within the sleeve at an open end thereof a plug having a larger cross-sectional size at a first position away from said open end and a smaller cross-sectional size at a second position towards said open end; (c) positioning a heat-activatable sealing material at the first position; (d) shrinkable conduits in the sleeve by positioning one or more clips at the open end of the sleeve such that the substrates and the plug are in respective conduits; and (e) while the clip remains on the sleeve, applying heat so as to affect shrinkage of the sleeve to activate the sealant, and form the desired seal.
