Abstract: A cooking grate configured especially to accommodate and cook generally cylindrical food items such as frankfurters and sausage is provided. The design permits the cooking of cylindrical food items faster, more efficiently, and more evenly while minimizing undesirable burning and charring. The apparatus includes a unitary grate body made from a heat-conductive material which grate body has an upper cooking surface, a lower heat collecting surface, a rear edge, a forward edge, and left and right sides. The grate body is corrugated to form a plurality of substantially parallel and adjacent cooking troughs extending in the transverse direction from the rear edge to the forward edge. Each cooking trough has a spine as its lowermost portion and left and right cooking faces originating at the spine and diverging upwardly to converge upon the right and left cooking faces of the adjacent tough respectively to form peaks at the junctions of the same.

Abstract: A concentric nebulizer having applicability in inductively coupled plasma spectrometry is disclosed. The device features a nebulizer tube with a tapered front open end and mechanism for removing, replacing, and adjusting the position of central sample capillaries with respect to the opening in the front end to adjust such parameters as gas pressure, sample flow rates, and aerosol formation over a wide range. Devices constructed in accordance with the invention may operate at low gas pressure and are physically compatible to glass concentric nebulizers.

Abstract: There is provided a liquid atomizing spray gun of the general type that produce single, finite bursts of gas/liquid mixture which overcomes disadvantages of prior designs in that it does not depend for pressurizing and propelling gas on the squeezing of a trigger while aiming the device throughout the spraying stroke and in which a gas compressing piston is not driven by or otherwise directly mechanically linked to a trigger. These and other objectives are achieved in part by providing a spray gun with a chamber containing a gas tight piston that is reciprocable within the chamber, but wherein the piston is not reciprocated by the trigger. Instead, the piston is independently drawn to a rearward position for drawing gas into the chamber through a one way gas intake valve by the creation of a partial vacuum within the chamber. The piston is then released and biased forward to compress the gas within the chamber.

Abstract: An ergonomic handle for a spreading tool designed to permit and encourage the user to grasp the handle with his/her fore and middle fingers extended onto the blade. The extended fingers are fully supported by an arch in the head of the handle, which combined with its comfortable gripping portion for the palm, thumb, ring and little fingers, allows proper alignment of the wrist and increased leverage on the blade while working the tool, yet minimizes fatigue, pain and the potential for injury.

Abstract: An improved cut plant watering apparatus for detecting and indicating a predetermined water fill level to prevent overfilling and spillage when watering a cut plant, such as a Christmas tree, mounted in a container comprising a conduit for carrying water from a fill location to the container, an indicator in communication with and responsive to a detector that, when used to fill the container with water, indicates that the predetermined water level has been reached so that a person does not inadvertently overfill the container, thereby eliminating water damage to surrounding objects or to the carpet and floor.

Abstract: A safety apparatus and method for indicating the presence of a translucent medium comprising a magnetic structure having a removably attachable visible element portion that, when positioned on a translucent medium such as a patio door, screen, window or the like, warns of the presence of the translucent medium so that a person does not inadvertently attempt to walk through the translucent medium thereby risking serious injury or bodily harm.

Abstract: An apparatus for soaking and preserving several paint roller covers in wet suspension in a receptacle comprising a rack on which several easily removable paint roller covers are positioned in spaced relationship. The apparatus provides economical cost saving use of paint rollers, convenience, time saving and ecological advantages whereby no washing or rinsing is necessary, from a faucet or hose, for instance, thereby conserving water. The resulting apparatus allows a person the capability of extending the useful life of a paint roller covers by preserving used paint roller covers and rejuvenating them for further use.
