Abstract: A control system for an underwater camera housing, including a pin assembly within the housing wall. The pin has a clamp ring and a set of O-rings at an end of the pin. The pin is received into a well in the housing. A spring is received into a bushing also positioned within the well, with the pin inserted into the center of the spring, and the spring compressed against the seat of the bushing by the clamp ring. The pin is depress-able to contact a control button of the housed camera. The control system additionally includes a knob rotatably attached to the housing's exterior. The knob has a boss magnet to move a worker magnet positioned on the housing's interior. The knob is rotatable to move the boss magnet, and so move the worker magnet, to control functions of the housed camera.

Abstract: A collar system for a connecting the cab of a vehicle to the cargo bed cover or similar boxed attachment, the vehicle mounting collar including a webbed collar frame designed to mount to a standard driver's compartment or cab, without modification to the vehicle. The collar and attachment method are extremely flexible and accommodates any vehicle tolerance variation. The collar mounts to the rear flange on the cab of the vehicle, and the bulkhead of the collar has slots to receive the shell of the cargo bed cover. Shell bolts within the bulkhead slots allow the shell to be adjustably repositionable on the bulkhead of the collar by slippage of the shell bolts within the bulkhead slots.

Abstract: An apparatus for tilt-able rack system especially suited for a vehicle, such as a pick-up truck. The tilting rack system includes a stationary upright support frame, and a hinged upright support, with the hinged upright mounted to the vehicle rearward of the stationary upright. A slide-able and tilt-able pair of rails mount to the support frame at the hinged and stationary uprights. As the hinged uprights lever rearward and downward, by action of a hinge at the base of each upright, the rails can slide and tilt upon a sliding hinge at the top of each stationary upright. The rearward, hinged uprights may be actuated by hydraulics, manual cranks, cables, or any other such mechanisms. The entire rail and associated frame can tilt down to the rear of the vehicle, allowing the easy placement of long items on the frame, such as ladders, pipes, boats, boards, and panels.

Abstract: A system for arranging and operating an array of wind machines to protect crops from damaging weather conditions, such as freezing frost, rain and heat. The method includes a wind machine positioned to force air across the crop. The wind machine is preferably a propeller/tower configuration. The operational method of the wind machine array includes the steps of sensing ambient meteorological and the hardiness of the crop to withstand a particular adverse weather condition and operating the wind machines in response to these factors. Multiples of wind machines are employed in the preferred embodiment of the method, the siting of the wind machines preferably based upon topographic and historical meteorological conditions. The operation of the wind machines can be automatically and remotely operated with the aid of satellite communications including internet links.

Abstract: A cattle foot-bath system, specifically adapted to mix and charge foot-bath troughs with repeatably precise quantities of chemical treatments. The system administers a concentrated medicinal agent, such as a bactericide, a fungicide, or a viruscide, for the treatment of cattle feet, and includes a day-tank feed valve, which may be a three-way or interlocked valve, for controlling an infeed flow of the concentrated medicinal agent fed into a day tank, which may be mounted to a portable tote-tank containing the concentrated medicinal agent. A day-tank drain valve controls an outlet flow of the concentrated medicinal agent drained from the day-tank, and the day-tank holds a set quantity of the concentrated medicinal agent. A footbath then receives a quantity of dilution water and the set quantity of the concentrated medicinal agent from the day-tank.

Abstract: A low-profile sweeper that employs rotary brushes. The low-profile sweeper is especially suited for low overhead clearance applications, as typically found in nut harvesting. The low-profile sweeper has an armature for locating one or more brushes in an array, or attached to a conventional agricultural sweeper. The armature attaches to a chassis or frame of a steerable drive. When used in a parallel oriented array, the brushes rotate in the same, common direction and in substantially the same, common plane of rotation, slightly skewed to avoid contact between the brushes. The bristles of the radial brushes are emanate fro a central hub and are approximately parallel to the plane of rotation. A fan can be utilized to aid the pick-up action of the brushes. The fan is preferably mounted to direct an airstream to the area to be swept. Also, a spray-bar can be attached to the armature or alternatively to the chassis, to aid in dust abatement.
