Abstract: A food cooking and heating cabinet having a closed air convection system consisting of a variable speed blower in a air heating chamber for circulating air past a variable heating element, through a food holding oven, and back to the air heating chamber, a control for selecting a desired temperature to be maintained in the food holding oven, and means for comparing the temperature at the outlet and the inlet of the heating chamber to the selected temperature causing the air variable heating element to operate and the speed of the blower to increase when more heat is required and reduces both heat and blower speed as the need for the higher heat and air flow is no longer required, and when preset parameters are reached automatically sets the temperature to a preset temperature and holds the heated product to the predetermined temperature.

Abstract: The improved integral keyboard and storage organizer of the present invention provides a keyboard with a housing that can be hingably or slideably opened to access an integral storage organizer and has latches to maintain it in a closed arrangement, has a locking mechanism to secure the contents and has a separate access compartment for replacement of batteries and access to electronic components.

Abstract: An asbestos free, calcium silicate insulating material, suitable for use in applications where a tough, fire resistant, heat insulating, electrical insulating, and corrosion resistant material is desirable. The calcium silicate insulating material is produced by combining Portland cement, blast furnace slag cement, a siliceous component, wollastonite and organic fibrous material in the presence of water to form a slurry. The slurry is then placed under steam pressure, to react the portland cement, blast furnace slag cement, siliceous component and water, dried, and heat treated if necessary.

Abstract: An asbestos free, calcium silicate insulating material suitable for use in the casting of molten non-ferrous metals, and suitable for use in applications where a fire resistant, heat insulating, electrical insulating, and corrosion resistant material is desirable. The calcium silicate insulating material is peoduced by combining lime, a siliceous component, alumina silica microspheres, wollastonite and organic fibrous material in the presence of water to form a slurry. The slurry is then placed under steam pressure, to react the lime, siliceous component and water, dried, and heat treated if necessary.

Abstract: A drainage support/diverter system for use in connection with a perforated pipe drainage system within a drainage trench, comprising a number of drainage support/diverters that create impermeable barriers to moisture flow along the length of the trench outside the perforated pipe, such drainage support/diverters are positioned upon intervals along the drainage trench with their lower ends placed to a depth at least as deep as lowest depth of the drainage trench where each drainage support/diverter is placed, extend laterally at least as wide as the widest point of the drainage trench where each drainage support/diverter is placed and are formed at their upper ends with a recess corresponding to a portion of the diameter of the perforated pipe such that moisture outside the perforated pipe is forced to enter the perforated pipe at the point of each drainage support/diverter.

Abstract: A playing card deck particularly suited for the play of the card game of blackjack where indicia that is irrelevant to play of the game has been eliminated to facilitate play and increase the pace of play of the game. The invention comprises a deck of fifty two playing cards with the cards of the deck having no indications for suits and having four cards each with value indications of ace, two, three, four, five, six, seven, eight, and nine, with the remaining sixteen cards having value indications of ten.

Abstract: The integral keyboard and storage organizer of the present invention provides a keyboard with a housing that can be hingably or slideably opened to access an integral storage organizer cavity. It provides for convenient organized storage of traditional desktop supplies, sundry computer related items and personal items, at no appreciable additional cost to that of a standard keyboard, and without occupying any valuable desktop space in addition to that required by the footprint of the keyboard.

Abstract: A drainage system for collecting, isolating and relocating moisture incorporating cascading chutes which collect moisture and create an inner channel from which collected moisture cannot escape to re-infiltrate surrounding soil prior to its discharge point.

Abstract: A low cost analog deflection sensor assembled from a single component part which lends itself for use as a joystick. A central contact is surrounded by peripheral contacts and aligned by a dielectric spacer. Application of deflectional force results in one or more signals of measurable resistance which can be translated into speed and directional vectors.

Abstract: A self service sales and security system for use in the retail sales environment including a means for identifying the presence, removal, and addition of each item of inventory on a merchandise rack and correlating the removal or addition of each item of inventory to an identifiable customer so that the customers can be automatically billed or charged for the items of inventory that the customer removes, and a report of which items need to be ordered to replenish inventory can be automatically prepared. The self service sales and security system includes customer records which may include credit information to selectively allow customers to remove only such items of inventory as their credit information allows; and an alarm is included to indicate tampering or the unauthorized removal of any item of inventory.

Abstract: A low-cost miniature joystick pointing device with improved performance, which may be mass produced from a small number of component parts, and which lends itself to production by automated machinery. An inner conductive contact is disposed inside of and surrounded by one or more outer contacts where deflection of the inner or outer contact results in a measurable resistance which may be interpreted by analog to digital or RC timing circuitry to produce speed and directional output.

Abstract: A compact, low-cost pad pointing device with improved performance, reliability and durability, having an integrated selection switch, that can be used as a cursor pointing device and selection mechanism for computers, remote controls, web TV, TV guide browsers, video games, consumer electronics, industrial controllers, medical, automotive and other applications. A contact surface can be deflected to positions on an electrical medium that results in the generation of speed and direction signals while a selection switch may be simultaneously activated through the same control element.

Abstract: A low-cost pad pointing device with improved performance, reliability and durability, that can be used as a cursor pointing device for computers, remote controls, web TV, TV guide browsers, video games, consumer electronics, industrial controllers, medical, automotive and other applications. A protruding plus shaped segment can be deflected to positions on an electrical medium that results in the generation of a speed and direction signal to be interpreted by low cost available circuitry including microcontrollers.
