Abstract: The present invention is related to a new and non-obvious device for adjusting the length of a leg associated with, for example a ladder, tripod or the like. Prior art leg adjustment devices are not without their problems being either extremely complicated and, therefore, expensive to build or difficult to use, heavy or limited to specific adjustment lengths.

Abstract: The present invention relates to a mobile pet bed wherein the top and bottom units of the mobile pet bed are reversibly attached to each other. When the top unit is removed from the bottom unit the mobile pet bed functions similarly to a traditional pet bed. When the top unit is attached to the bottom unit the mobile pet bed functions as a pet carrier. Additionally, the top unit of the mobile pet bed has a door portion that can be opened and closed to permit pet ingress and egress as well as permitting easy loading of the mobile pet bed with the animal without necessitating the removal of the top unit from the bottom unit.

Abstract: The present invention relates to novel devices and methods of filling tanks designed for holding non-hazardous fluids, especially tanks on recreational vehicles. In a preferred embodiment, the tank to be filled is a water tank. The device of the present invention incorporates several novel and non-obvious features to create a device that permits the filling of tanks in a hands-free manner while keeping water waste to a minimum and preventing the damaging of tank, fill neck or other tank or fill components due to the over filling of the tank.

Abstract: The present invention relates to devices, kits and methods to aid the home owner in the transport of salt to their cellar-based water softening system. The device of the present invention uses rectangular piping because of the greater ease of supporting the piping and greater stability during use.

Abstract: The present invention relates to a device for easily and accurately marking, scoring and cutting drywall sheet material, the device having a general appearance of a T-square and comprising gripping pins for securely holding the T-square on the sheet material to be marked, scored or cut.

Abstract: The present invention is directed towards a device and method of use for ensuring that persons who need to stay on a schedule can do so without constantly looking at a clock. The device is a programmable electronic device wherein the user can set a schedule time, an interval time and a sub-interval time and wherein the device alerts the user when one or more of these times are reached.

Abstract: The present invention is directed towards inexpensive and reliable devices and methods for testing the calibration of torque wrenches.

Abstract: In one aspect, the invention relates a rearview mirror wiper system suitable for use on, for example, large tractor-trailer trucks, delivery trucks, vans, motor homes, cars and other motor vehicles. The rearview wiper system of the present invention has many advantages over prior art systems. It ensures an even and adjustable pressure over the entire wiping surface, has a minimum of parts exposed to the elements so that it is less susceptible to icing and is easy for the user to maintain.

Abstract: The present invention relates to a device for easily and accurately scoring and cutting drywall sheet material, the device having a general appearance of a T-square and comprising rollers under the portion of the device that contacts the edge of the drywall sheet, a movable blade and blade holder and other features to aid the user in scoring and cutting drywall.

Abstract: The present invention relates to a novel and non-obvious propulsion system for watercraft, especially, but not limited to, watercraft less than about 50 feet in length. Propulsion system of the present invention provides a system that is less prone to being impeded by debris, water plants and the like; less likely to cause motor stalling or motor over heating if said propulsion system does become clogged or impeded and is designed to provide increased thrust resulting in, for example, more efficient operation.

Abstract: This invention provides novel devices and methods for the heating of air with solar radiant energy. The devices of the present invention feature a housing partitioned into essentially isolated sections wherein the sections are in fluid communication with each other through a plurality of channels located within the partitions. The two unique features of the invention, essentially isolated sections and partitions comprising a plurality of channels, increase the temperature achieved by the solar heater by 1) creating multiple, sequential sections that function independently of each other providing a higher starting temperature in each section and, therefore, a higher final temperature, 2) providing second means of heating the air within the channels located within the partitions and, 3) by virtually eliminating the mixing of incoming cold air with the heated air of the solar air heater.
