Abstract: UMBRELLA               ABSTRACT OF THE DISCLOSURE        An umbrella is convertible between an expanded and contracted position to adjust the area of coverage thereof when the umbrella is in the opened condition.  The umbrella is formed with a pair of sticks which extend from the handle thereof with the sticks being pivoted at the handle for movement between a spread position whereby the sticks may be placed in a generally V-shaped configuration, and a position wherein the sticks are brought together to be generally parallel with each other.  Each stick includes a slider which may move relative to the stick in order to effect opening and closing of the canopy of the umbrella, which canopy is generally supported upon the ends of the sticks by ribs.  With the sticks in a generally parallel position, a smaller area of coverage is provided by the umbrella.  By spreading the sticks apart into the V-shaped configuration by pivotal motion thereof about the handle, the canopy of the umbrella is spread to cover a larger area and the umbrella may be used, for example, by two persons.

Abstract: CONTRAST/COLOR CONTROL FOR A TELEVISION RECEIVER     ABSTRACT OF THE DISCLOSURE     Control circuitry for selectively controlling the contrast of a video picture displayed by a television receiver and for selec-tively controlling the color level of the video picture.  The television receiver is of the type which has a controllable video amplifier for amplifying a luminance signal and a controllable chrominance amplifier for amplifying a chrominance signal.  The control circuitry includes pulse generating circuits for generat-ing contrast control pulses of selectively variable duty cycle and color level control pulses of selectively variable duty cycle.           A contrast control circuit is responsive to the contrast control pulses for generating a contrast control signal in accordance with the duty cycle of the contrast control pulses.  The produced con-trast control signal is used to control the gain of the video am-plifier to as to correspondingly control the contrast of the video picture.  A color control circuit responsive to the color level control pulses generates a color level control signal in accord-ance with the duty cycle of the color level control pulses, and the color level control signal is changed proportionally with a change in the contrast control signal so as to maintain a substan-tially constant chrominance-to-luminance signal ratio despite changes in the contrast control signal.  The color level control signal is used to control the gain of the chrominance amplifier so as to correspondingly control the color level of the video picture.            In one embodiment, the duty cycles of the contrast control pulses and of the color level control pulses are remotely controlled, as by ultrasonic transmitting/receiving devices.                             -i-

Abstract: ABSTRACT OF THE DISCLOSURE    A vertical post extends through the center of an enlarged central opening in an annular circular disc.  Manually adjustable mechanisms removably secure the disc to the post in such manner as to permit the angle between the plane of the disc and the axis of the post to be set at any value between -X and X, where X as expressed in degrees can range between 0 and somewhat less than 180.  A first elongated vertical member with a semicircularly shaped central section has upper and lower hori-zontally elongated hollow tracks extending in the same direction and coplanar with the section.  The post passes through the tracks and section with clearance so that the member can be moved vertically up and down with respect to the post and also can be rotated around the post.  A second elongated vertical member has a straight vertical central section provided with a guide mechanism engagable with an disengagable from the periphery of the disc.  The second member has parallel horizontal upper and lower rails at corresponding upper and lower ends of the straight section. Each of the rails slidably engages a corresponding one of the tracks and is horizontally movable therein.  A marker device slidably engages the lower rail and is securable thereto.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved wire wound disc type armature for electric motors or generators. The armature has a disc shaped body mounted on a central shaft with a commu-tator formed of spaced insulated commutator elements located around it.  The disc shaped body has opposing flat sides on which a predetermined number of  wire windings are located.  The insulated wire forming each winding extends outward from the commutator through a U-shaped wire channel on one side of the disc shaped armature and back through a corresponding wire channel on the other side.  The disc shaped body of the armature is formed of high strength plastic and the wire channels are formed of laminated steel.  In one embodiment, the wire then passes through an aperture in the disc shaped body associated with each winding and back out through the first wire channel and this is repeated until a winding of a desired number of turns is formed in the two channels.  This structure and winding configuration provides the significant advantage that the amount of wire used which does not pass through the magnetic field during use is kept to a minimum. This reduces initial wire costs and more significantly, decreases heat and other losses which otherwise occurs in the excess wire, as well as minimizes interference currents which may be induced on current reversals.
