Abstract: A tool head suitable for use in a machine tool for shaping the edge of a plastic sheet, which holds and shapes the edge of plastic sheet while a vacuum on the machine tool holds the center of the plastic sheet. Having such a desired edge renders the plastic sheet suitable for further manufacturing treatment.
Abstract: A vehicle mounted cleaning device cleans a series of large garbage containers at one at time, while recycling, reusing and retaining the cleaning fluid, until disposal thereof is required. The vehicle mounted cleaning device permits the vehicle to be maneuvered down a street. The cleaning device has a cleaning bin or wash bay to receive the garbage or trash container. A cleaning fluid tank communicates with nozzles in the wash bay to provide fluid for cleaning the garbage container. After the fluid is used to clean the garbage container, it is filtered, treated and returned to the cleaning fluid tank for reuse.
Abstract: A periodic tester to determine the readiness of a fire pump system interfaces with a fire pump controller, an electric motor, and a sprinkler system. The fire pump controller has a power on/off sensor which interfaces with an electric motor which starts the fire pump to provide water to the sprinkler system. The power on/off system has a contactor coil as a component. The periodic tester targets two of the main components of fire system failure: the power on/off sensor and the contactor coil. The periodic tester may be retrofitted to existing systems and interface either directly or indirectly with the power on/off sensor to accommodate both systems that have a solenoid valve and those that do not. The periodic tester is designed to attempt to start the system only once during a set cycle. Any failure to start is displayed through audible and visual alarms.

Abstract: A reversely mountable tactile switch assembly has a switch housing with switch terminals and an actuator button secured thereto on the same side of the housing, and can be used on a printed circuit board. The resulting printed circuit board provides for smaller units to be used, especially with appliances.
Abstract: A cover for a stethoscope, and in particular the bell or diaphragm of a stethoscope, has a semi rigid center portion with a flexible skirt extending therefrom. The skirt and the semi rigid center portion terminates in an expandable binding ring, thereby permitting the cove to be applied thereto. The cover may a unitary or a multiple piece.
Abstract: An inflatable bed is filled with a fluid, whether it is a gas or a liquid, a desirable, in order to form a comfortable bed. The durable pet bed has at least two layers of bullet resistant fabric therein, with a fluid chamber therein protected on all sides by the bullet resistant fabric layers and capable of receiving a gas, fluid, gel, or liquid to provide comfort and safety for the pet using the bed.
Abstract: A negative density range control system uses color hue contrast to provide a print of a picture, by comparing the relationship between negative hue density and print emulsion density requirement and providing an appropriate density for a printing process, whether converting a positive digital image to negative digital image with a specific hue density color or making a print by contact printing a hue density negative rendered from a digital image file.
Abstract: A protective and insulating cover for an injured limb, especially a foot or a leg, is formed from fleece or other material, which is stretchy and warm with a double layer of material at the toes and hook and loop fasteners at the top, thereby forming a cast cover, which is warm, easily applied and removed, adjustable, and decorative.
Abstract: A clutch device is adapted to fit onto a drive shaft of a standard water pressure cavity machine. The clutch device has a clutch body with a shaft receiving aperture at one end of the clutch body and a spring assembly at the other end of the clutch body. Reciprocating jaws are held in position by the spring assembly.
Abstract: A road safety reflector assembly has a pair of oppositely disposed finger cradles with a hollow, reinforceable housing, which has one or two reflectors mounted therein.
Abstract: A nursery cultivating assembly is carried on a modified zero turning radius tractor and includes a cultivating device, a spraying device, and a tank assembly operably interconnected thereon, while providing for trees to be planted closer together.
