Abstract: A support for conventional roll of perforated paper towelling includes a base for mounting on a vertical or horizontal surface, a support rod perpendicular to said base for holding the towel roll, and a manually operable braking device for impeding the unrolling of the towels when one is being torn off the roll.

Abstract: A snap-on swimming pool gutter cover is formed of a generally planar major portion including a rear edge and an inverted, channel-shaped, front, female portion which snaps down onto a correspondingly shaped male portion of the gutter lip. The rear edge is received in a horizontal slot in the rear wall of the gutter.

Abstract: In a printed circuit, a plurality of drive electrodes are arranged in an array which is symmetrical about a center detector electrode. A plurality of conductive arms extend outwardly from the center electrode between adjacent electrodes in the array. One of the conductive arms extends to a contact point outside the array and provides electrical communication in the form of an electrical conductive path from the center electrode to the contact point. The remaining arms terminate substantially co-extensive with the radial extremity of the drive electrodes in the array and eliminate inadvertent imbalances in the output signal from the array.

Abstract: The cam shaft of a fluid jet loom, which cam shaft normally operates the warp yarn harness frames, is disengaged from the machine drive mechanism by a clutch mechanism. The cam shaft is then rotated manually by the operator, as the machine drive is by-passed, to reposition the harness frames at a proper position such that faulty picks can be easily removed.
