Abstract: A sectionalized surfboard, which can be dismantled into sections and rejoined for use. The sections are joined using a vertically installed bolt or pin. The bolt or pin is inserted through holes in metal plates mounted securely to the stringer on one section and a tube mounted securely to the stringer of the other section.

Abstract: A TV frequency modulation feedback loop (FMFB) remote volume control includes an RF input and a mixing means with the RF input being connected to and providing one input for the mixing means. A voltage controlled oscillator is connected to the mixing means and provides the other input thereto. The output from the mixing means is an IF FM sound signal which is connected to a demodulator. A remotely operable deviation control is connected to the output of the demodulator for changing the amplitude of the demodulated sound signal. The deviation control is connected to and provides a deviation controlled input for the VCO.
