Abstract: A magnetron cathode comprises electron emissive material included in a cathode body and a support structure for supporting the cathode body. The support structure has a longitudinal axis and includes a first part having a first cylinder integrally formed with a first end hat and a second part having a second cylinder integrally formed with a second end hat. The first cylinder and the second cylinder have an overlapping region in the longitudinal axial direction and are joined together. The cathode body is located around the first cylinder of the first part of the support structure and is joined to the first cylinder by a brazed joint. The outer surface of the first cylinder is grooved at the brazed joint.

Abstract: The present invention is a unique advanced hybrid iron type golf club. The club is characterized by a long blade length with a long heel blade length section, while having a small club moment arm, Zcg, and volume, and producing a high moment of inertia. The golf club incorporates the discovery of unique relationships among key club head engineering variables that are inconsistent with merely striving to obtain a high moment of inertia using conventional golf club head design wisdom.

Abstract: According to the present invention there is provided a method of analysis of the audience for channels selectable by a channel selector device for presentation on a presentation device, the channel selector device providing data indicating which channels are selected and the lengths of time for which selected channels remain selected. The data relating to the lengths of time for which channels remain selected is subject to a capping procedure, whereby the indicated length of time for which a channel remains selected is reduced to a capped maximum permitted length of time if the indicated length of time exceeds the maximum permitted length, to provide capped data.

Abstract: The present invention is a unique fairway wood type golf club. The club is a high moment of inertia fairway wood type golf club characterized by a long blade length with a long heel blade length section, while having a small club moment arm and all the benefits afforded therefrom. The fairway wood incorporates the discovery of unique relationships among key club head engineering variables that are inconsistent with merely striving to obtain a high MOIy using conventional golf club head design wisdom. The resulting fairway wood has a face closing moment of inertia (MOIfc) that provides golfers with a feel similar to that of a modern driver or hybrid golf club.

Abstract: A golf club head includes a striking face and a sole plate coupled to the striking face. At least one support bar extends between the striking face and the sole plate, wherein a weight member is selectively secured to the at least one support bar. In accordance with an alternate embodiment, the club head includes a heel and a toe, as well as a striking face and a rear surface opposite the striking face. A support bar extends from the toe to the heel along the rear surface of the club head body, wherein a weight member is selectively secured to the at least one support bar. In accordance with yet a further embodiment, a rail extends along the sole plate and a weight member is mount within the rail for movement relative thereto.

Abstract: A golf club head includes a club head body having a plurality of recesses and a plurality of weight members shaped and dimensioned for selective placement within the recesses.
