Abstract: TRACTION-DRIVE TRANSMISSION WITH HYDRAULIC CONTROL                 ABSTRACT OF THE DISCLOSURE      The invention contemplates an improved mechanical traction drive with a hydraulically implemented single control whereby a desired range of speed ratios between input and output shafts is selectively available, without requiring clutch connection to the power source, such as a battery-operated electric motor.  The transmission employs a combination of completely mechanical friction-roller and meshing-gear planetary systems which are connected at all times, whether the single control is operated to call for a forward drive or a stop, and whether the motor is run in the direction to produce a forward or a reverse drive of the output shaft.  Provision is made for auto-matically downshifting and upshifting the transmission via hydraulic means, in response to input-torque requirements and/or output-torque limitations.

Abstract: RCA 71,398 Abstract A comb filter comprising a charge transfer device (CTD) structure for separating frequency interleaved luminance and chrominance components of a composite color television signal directly within the CTD structure.  The CTD structure has first and second pairs of input sections of substantially identical geometry, one input section of the second pair being preceded by a signal inverter.  Signal charge as applied to the first and second input pairs are delayed such that signal charge from the first input pair exhibits a l-H delay relative to signal charge from the second input pair, when the signal charge from the respec-tive input pairs are combined with each other.  A first charge summing well combines mutually in-phase signal charge at multiples of the line scanning frequency from the first and second inputs to provide a combed luminance signal charge component, while a second well combines mutually inverted or out-of-phase signal charge at these frequencies from the first and second inputs to provide a combed chrominance signal charge component.

Abstract: PANEL REPAIR KIT          ABSTRACT OF THE DISCLOSURE A kit for repairing a hole or providing a more substantial mounting for an anchor device, as in a panel of a hollow construction, such as a room partition or a hollow door, including a thin sheet of perforated material which is cut to form a plate slightly exceeding the size of the hole after it has been squared-up.  A suitable adhesive, such as two-sided adhesive tape, is applied to a face of the perforate plate along substan-tially the entire periphery of the plate.  An opera-tively rigid tool, having resilient legs with feet at adjacent ends, has its legs slightly spread apart and the feet inserted through spaced apart ones of the perforations until the legs seat in these perforations and the tool is generally perpendicular to the plate. A rod is then inserted through a perforation preferably aligned with and equally spaced from the perforations receiving the legs.  An outer end of the tool has a recess which receives the rod, so that the tool and rod may be held by the fingers of one hand for inserting the plate through the hole and then pulling outwardly on the tool so that the adhesive secures the plate to the inner face of the panel being repaired.  The rod is then pushed through the perforation until it is seated against a fixed portion of the hollow construction, such as another panel, for example.  The rod may be smooth, in which event friction between the rod and the plate operatively fixes the rod and plate to each other; or the rod may have abutments for engaging the panel about the perforation, to operatively fixedly secure it to the rod.  The outer portion of the rod is then broken off proximate the plate, and the hole is filled with a suitable patching material.          This invention relates to a repair kit and, more particularly, to a kit for repairing a hole in a panel of a hollow construction, and to an installation tool forming part of the kit.
