Abstract: A boat trailer has a unitary fender having a base to which there is attached a light and license plate support bar. The unitary fender is attached to the trailer running gear by suitable brackets and bolts. The light support bar is pivotably attached at one end to the base near the center thereof and is releasably fastened to the base near the rear of the fender. A bracket for supporting a lamp and license plate is attached to the opposite end of the bar. Electrical wires extend from the vehicle's electrical system through the fender and bar to the lamp. The bar is fastened to the base in such a fashion that the lamp and license plate are repositionable from the rear of the trailer where the lamp and license plate are located during over-the-road travel to a position forward of the fender prior to launching a boat from the trailer. In this regard, the bar is released from the base of the fender and rotated 180.degree.

Abstract: Water-borne reaction products of (a) carboxyl-functional polymers; (b) polyepoxides; and (c) tertiary amines are blended with (d) carboxyl-functional polymers having an acid number dissimilar to that of (a). The resulting products are useful as film-forming components of coating compositions which can be spray-, flow-, dip-, roller-, or electro-coated and are especially useful for spray coating the inside of two-piece tin-plated steel cans of beverages and food. The coating compositions are useful as such or can be crosslinked with crosslinking agents such as a nitrogen resin.

Abstract: A solid state, band-pass filtered, RF power amplifier for equalizing the response of an amplified RF signal across the entire tuning range of a multi channel transmitter is disclosed. An RF signal is applied to the input of a low noise FET amplifier with a portion of the signal coupled off into a frequency counter which in conjunction with a digital switching logic selects a path through a band-pass filter having characteristics that reduce the broadband noise of the RF signal passed therethrough. Additionally, a dual directional coupler samples the output of the power amplifier with the forward sampled signal being used to control the amplifier output to a preselected level and the reverse sampled signal being used to reduce the amplifier output signal in proportion to an increase in the voltage standing wave ratio load between the amplifier and the transmit/receive switch.
