Abstract: An evaporative cooling apparatus is provided that may be quickly deployed to cool an area. The apparatus is preferably self-contained or substantially self-contained. The apparatus can be either a dedicated trailer with a conventional draft vehicle or a vehicle itself or a permanently dedicated apparatus. The apparatus creates an evaporatively cooled volume of air with fine entrained water droplets suspended therein. The apparatus transfers the cooling suspension to an area to be cooled proximate the apparatus.

Abstract: Multiple range-of-motion mower deck support arm apparatus and kits are provided to improve the lateral float of a mower deck. Rod end bearing are utilized to provide an additional range of motion to prior art vertical only designs. The present invention utilizes a front left floating arm, a front right floating arm, a back left support assembly, and a back right support assembly which are all pivotally supported from the existing frame connection apertures and the existing mower connection apertures to vertically pivot in relation to the mower deck and vertically, horizontally, and rotationally pivot in relation to the lawn tractor frame.

Abstract: A screed with a trussed beam having a cross-section in the geometrical shape of an equilateral triangle used to support tools for working plastic concrete. The beam is supported between spaced apart, wheeled carriages riding forms bounding the plastic concrete. The beam is oriented such that the cross-sectional triangle is inverted with the wide base at the screed top and the apex at the bottom. The inverted triangular truss beam has sufficient space to suspend working tools substantially within the peripheral edges of the beam. The screed uses upstanding integral outriggers so that the pitch at the center of the screed can be adjusted exteriorly to the pour site. A rotary spreader displaces concrete forwardly without deleteriously compressing it as the screed moves forwardly.

Abstract: A conveyor oven for cooking food items, having a conveyor belt that passes through the oven. The conveyor belt may include a plurality of tablets composed of a stone-like material attached to a stainless steel linking assembly, or alternatively, a drive chain. Infrared radiation heat sources are provided above and below the conveyor belt. Food passing through the oven on the conveyor belt is cooked by heat transferred directly from radiant heat sources. Cooking is also facilitated by heating stone-like tablets of the conveyor belt with infrared heat sources inserted inside the conveyor belt loop. Heat is transferred from the tablets to the food items, producing superior qualities in the cooked food. Waste heat is reduced by providing a means for automatic control of the heating elements.

Abstract: The present invention efficiently and safely combines directed air flow for drying and heat removal with panel infrared emitters that provide thermal energy for curing LPI solder mask and legend inks onto printed circuit boards being transported though an area with pneumatic and radiant processes occurring simultaneously. The internal geometric configuration of the apparatus and high velocity input air results in an airflow stream in relation to the panel infrared emitters that ensures any flammable vapors are kept separated from the infrared emitters.

Abstract: A protective device particularly suited for use by females after childbirth generally characterized by a plastic shield for protecting the episiotomy or perineal tear surface from urine flow while urinating over the toilet. The device consists of a sole concave interior (20) plastic with adjacent handle (10) and contoured upper lip (22) adaptable to the female genitalia to be placed between the episiotomy or perineal tear surface and the urethra to alleviate the painful contact of urine on the wound and to promote healing.

Abstract: A light source switched on and off by direct means or being signaled to be switched by an alternate mechanism, and powered by direct electrical circuits, derivations of such direct circuits, or direct battery sources, to power said light source to shine such that a vehicle/equipment can be maneuvered to bring said light source to the same location on the vehicle/equipment thereby providing precise location of the vehicle/equipment.

Abstract: A process for the purification of water includes the addition of hydrogen peroxide and metallic coagulants in order to remove organic contaminants. Metallic coagulants increase the oxidative activity of hydrogen peroxide, while also causing the oxidized by-products to coagulate. The method is suitable for use in existing water treatment facilities. Optionally, an anionic polymer may also be added to enhance coagulation of the oxidized contaminants.

Abstract: An apparatus for cleaning floors which recycles waste heat and water to provide greater efficiency. An internal combustion engine is used to power the apparatus. Heat from the engine's lubricant is used to heat the wash solution applied to the floor. Heat from the engine's cooling air, radiator, and catalytic converter is used to dry the cleaned floor. A drying brush is also used to accelerate drying. Used rinse water is recycled for use as wash solution. Exhaust from the engine is used to preheat the floor to be cleaned. The engine may be used to propel the apparatus.

Abstract: A mobile cooling apparatus is provided that may be quickly deployed to cool an area. The apparatus is preferably self-contained or substantially self-contained. The apparatus can be either a dedicated trailer with a conventional draft vehicle or a vehicle itself. The apparatus creates an evaporatively cooled volume of air with fine entrained water droplets suspended therein. The apparatus transfers the cooling suspension to an area to be cooled proximate the apparatus.
