Abstract: - 19 -              RCA 73,673 Abstract of the Disclosure A combined phase shift and bandpass filter circuit in a color television receiver including color signal demodulators, and an automatic flesh tone correction network which provides a reference signal for the color demodulators, is disclosed.  The circuit comprises an integral bandpass filter and phase shift network coupled between the output of the flesh tone correction network and the reference signal inputs of the demodulators.  The circuit filters unwanted frequency components of the reference signal from the flesh correction network, and provides phase shifting of the reference signal as appro-priate for proper operation of the demodulators.  The circuit exhibits good phase stability, does not require alignment from receiver to receiver, and requires a minimum of connecting terminals to the flesh correction network and color demodulators.

Abstract: ASPHALT COMPOSITION SHINGLES            ABSTRACT          The present Invention relates to the field of roofing, and more particularly, non-metallic roofing such as asphalt composition and woodshake roofing.  Asphalt composition roofing of various types is very well known in the prior art and historically have been characterized as providing a relatively flat (i.e. non-three dimensional) roof, thereby having a minimal decorative character. Also, asphalt composition roofing, whether by way of conventional shingles or otherwise, has historically utilized a highly repetitive pattern in the roofing, thereby again limiting the decorative characteristic of the roof.  The disclosed asphalt composition shingles for new roofing and reroofing provide a three dimensional appearance not unlike shake but with the characteristic lower cost and fire retarding characteristics of asphalt composition materials.  The shingles may be cut from a standard roll of asphalt composition material, and are then folded to provide regions of differing thick-nesses because of the differing number of thicknesses of the material in the various regions.  The shingle design allows reroofing over existing shake roofs without requiring the stripping of the old roof.  Various embodiments are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE            A peripheral subsystem accepts and responds to a plurality of supervisory channel commands which alter the operation of the subsystem; i.e., logically partition, break the logical partition, adjust or amend the logical partition, ignore the logical partition, give operator controls for loading and unloading a record cartridge, suspending multi-path reconnection and the like.  These supervisory commands can be located anywhere in a I/0 chaining sequence.  Some of the supervisory commands will result in changes in the subsystem operation for the duration of the instant channel program or CCW chain while other persist for as long as the sub-system is operating or until a subsequent super-visory command overrides the previous supervisory command.  One of the supervisory commands can selectively inhibit subsequent supervisory commands only within a given I/O chain.  This selective inhibit provides subsystem integrity.  At the end of the chain, the inhibition is removed.

Abstract: -i-Abstract of the Disclosure A plastic material, preferably polyvinylidene fluoride (PVDF) film, made highly piezoelectric by known methods, is placed in a sensor unit structure wherein pressure is exerted against the piezoelectric film by means of rotation of the steering wheel of the boat or vehicle to thereby cause the piezoelectric film to generate electric signals which are used in controlling the rpm of a low-inertia, instantaneously re-versible steering power assist motor.  The rpm of the motor is substantially proportional to the electric signals, which, in turn, are determined by, and responsive to, the degrees of rotation and speed of rotation of the steering wheel. The direction of rotation of the steering wheel determines the direction of steering assist, i.e., to the left or right. Available torque of the motor however is substantially inversely proportional to rpm of the engine propelling the boat or vehicle.
