Abstract: A spark plug and method of construction thereof is provided. The spark plug includes a metal shell having a through cavity, a lower insulator and a plastic upper insulator. The lower insulator is received in the through cavity and has a through passage with a center electrode received therein. A ground electrode is operatively attached to the shell in spaced relation from the ground electrode to provide a spark gap. The plastic upper insulator has a distal end received in the through cavity of the shell and a terminal end extending axially outwardly from the shell. The upper insulator has a through passage extending between the terminal end and the distal end. An elongate conductive member is received in the through passage of the upper insulator and is configured for electrical communication with the center electrode.

Abstract: A holder for carrying an open umbrella on the back of a person. The umbrella holder includes a harness for securing the holder to the person and an umbrella supporting member. The supporting member is connected to the harness so as to position the umbrella proximate a center of the back of the person when the harness is appropriately secured. An attachment member permits attachment of the open umbrella to the supporting member. The attachment member optionally permits pivotal movement of the umbrella for optimum protection.
Abstract: A french fry cooking apparatus for deep-frying french fries includes a cooking unit having a plurality of frying baskets. Mounted above the cooking unit is a refrigeration unit which includes a first conveyor upon which a supply of frozen french fries is stored. The first conveyor discharges the fries onto a second conveyor which dispenses a metered quantity of fries to a delivery mechanism. The delivery mechanism includes a shaft and a rotatable directional chute for directing the frozen fries from the second conveyor into any one of the plurality of frying baskets. The frying baskets are pivotally attached to the cooking unit and are each movable by way of a drive unit between a loading/draining position for receiving fries from the chute and for draining oil from deep fried fries, a cooking position for deep frying the fries, and a dump position for discharging the deep fried fries from the frying basket. Deep fried fries are discharged onto a further conveyor which takes the fries to a holding bin.

Abstract: An improvement to a grain drying and storage structure which reduces moisture condensation on the inside of the walls of the grain drying structure by forcing heated air out through a peripheral opening at the top of the wall of the drying structure into a space between the wall and an external shell, thus heating the wall, and which allows moisture that condenses under the roof of the grain drying structure to drain to the outside of the grain drying structure so that it does not drain down onto the drying grain.
Abstract: A frying apparatus for food products is described which includes a fat holding tank, a transfer conveyor within the tank extending from one end to the other for transporting food products through the tank and a drive motor for the conveyor. The conveyor is preferably provided with upwardly extending, downwardly opening recesses to engage the top of the food products within the fat. The food products extend up into these recesses so that the engagement of the food products with the recesses is adapted to prevent slippage between the food and the conveyor. The invention also includes a provision for elevating and advancing incoming products within the fat to thereby transport them toward the outlet until securely engaged by the conveyor.
Abstract: A delamination resistant fried dough product such as a pizza shell having a unique structure is described. It is composed of a flat at least partially fried body of soft porous dough and crispable outer crust with a plurality of blisters having generally hemispherical upwardly extending domed upper surfaces. The blisters usually contain one or more cavities substantially larger in size than the pores of the dough. The blisters are spaced apart from one another laterally and ligaments of dough are located between the blisters to connect the upper and lower surfaces of the crust for the purpose of unifying the crust and preventing the top portion of the crust from becoming delaminated from the lower portion during the frying process. After the crust has cooled, a topping, such as a pizza topping, sugar or glaze, fruit, cheese, egg, custard, etc. is applied to the top surface of the crust which is then usually frozen.
