Abstract: Compositions for protecting materials from growth of pestiferous organisms, and particularly for protecting marine surfaces from fouling organisms, are formed from precursors having the formula ##STR1## where m is from 1 to about 10, where each X is independently selected from the group consisting of alkyl and alkoxyalkyl radicals containing less than about 6 carbon atoms and Y, where Y has the formula ##STR2## where R.sub.1, R.sub.2 and R.sub.3 are independently selected from the group consisting of alkyl, cycloalkyl, and aryl radicals, where R.sub.1, R.sub.2 and R.sub.3 contain in combination up to about 18 carbon atoms. The ratio of the tin atoms to silicon atoms in the precursors is at least about 1:50. The precursors can be directly used as an additive for coatings.

Abstract: An optical scanning and encoding device for providing a print signal pulse train to an ink jet printer in which a master image, including a reference image area, is scanned along a scan line. An optical scanner scans the master image and provides a signal which is inversely related to the print density of the image along the scan line. An integrator integrates the density signal during receipt of a gating signal pulse. A level detector detects when the integrator output has reached a predetermined level and provides a pulse to the printer and to an integrator reset circuit. A reference level means, responsive to scanning the reference image area, provides a signal output indicative of the maximum print density in the master image. A tachometer provides tachometer pulses at a frequency proportional to the rate at which the master image is scanned along the scan line.

Abstract: An improved uniform for ice hockey players is disclosed which provides improved protection for the player and a more streamlined appearance compared with traditional uniforms. The uniform includes an inner protective garment for the lower portion of a wearer's torso including the hips and the thighs, and an outer garment in the form of a long-legged pant to be worn over the inner protective garment and conventional shin pads. The inner garment comprises a shell provided with a plurality of pockets capable of receiving protective pads and including flap-like pouches at the sides of the shell for receiving hip pads. The pouches have lower portions which are free of attachment to the shell so as to permit relative movement of the underlying parts of the shell and allow a wearer reasonable freedom of bending movement at the hips. The pant includes ventilation panels for permitting air to pass through the garment.

Abstract: An air supply system for spas provides protection against motor short circuits caused by water backflowing through the air supply line to the housing containing the motor and blower. A moisture-proof partition isolates the motor from direct exposure to the air supply line. The partition and the blower air intake tube are arranged to prevent water from reaching the motor, unless such water first flows through the outlet ports of the blower and then through the blower air intake tube. The blower ports dissipate the water backflow pressure, thereby preventing backflow surges of short duration from reaching the motor. In addition, the inlet end of the air intake tube extends vertically well above the bottom of the motor to provide a static head to offset the backflow pressure of water in the air intake tube.In an alternative embodiment, a drain is provided by ducting the air intake tube to the exterior of the housing to positively prevent water from reaching the motor.

Abstract: A pool surface skimming apparatus is disclosed which has two concentric, substantially cylindrical shells engageable one about the other.

Abstract: A dock leveler or transfer bridge for ramps, comprising a bridge plate pivotally journalled at its rear end about a horizontal axis on a ramp. The front end of the bridge plate has a foldable or pivotal extension pivoted downwardly in the rest position and, in the working or effective position, pivoted into the plane of the bridge plate. The extension serves for exclusive support of the bridge plate upon the vehicle which is to be loaded or unloaded. When the dock leveler is not being used, the bridge plate is supported upon a pendulum-like strut or support located at the front end thereof. This pendulum-like support, by means of a lever pivotal with the extension, holds or maintains a pivot position for introducing the bridge plate into a ramp recess. In this pivot position, the strut or support cannot correspond or align with its abutment.

Abstract: A dual deflector element is disposed centrally of the lower unit of a floor sweeper and is adapted to serve two uni-directional brush rollers, disposed between the deflector and respective front and rear dust pans.

Abstract: A workpiece cleansing apparatus has a walking beam conveyor for transporting a camshaft to be cleaned to a first work station consisting of row of cradles which support the camshaft in such a way that oil ports therein are not blocked. Pressurized air is fed through an oil channel in the camshaft and passes through the oil ports to the exterior to remove moisture therefrom. The camshaft is then transported to a second work station where it is supported by cradles which mate with cradles so encircling the oil ports. The pressurized air is fed to the cradles and passes through the oil ports to the oil channel and thence to atmosphere.
