Abstract: A convection, oven having a multi-speed fan for circulating hot air within the cooking chamber at a plurality of velocities, with the selection of the appropriate fan speed depending upon the food being cooked in the oven. The fan is disposed within a recess formed in a rear wall of the cooking chamber and is separated from the cooking chamber by a fan cover plate. The cover plate has an inlet opening proximate its center and three elliptical outlet openings equidistantly disposed around its. perimeter. The edge of each outlet opening is located proximate an edge of the recess in order to provide a smooth flow path for the air circulated by the fan. To minimize the influence of the circulating air on the operation of the gas heating element, and thereby minimizing the production of carbon monoxide, a first of the outlet openings is located at a position 45 degrees above horizontal.

Abstract: A high molecular weight water soluble acrylamide based polymer having improved flocculating and dewatering properties is provided. The polymer is prepared by a process in which a small quantity of a chain branching agent is added to the polymerization reaction mixture continuously or stepwise while the monomers are polymerized. The polymer is useful in solid/liquid separations such as flocculants and coagulants in wastewater treatment applications, and as thickening agents.

Abstract: An improved method and system for detecting differences between first and second test executive sequence files in a computer system. Each of the test executive sequence files may comprise a plurality of interrelated objects. The objects may be compared and differences between the objects may be displayed. The objects may comprise one or more of: a sequence; a global variable; and/or a data type. A sequence may comprise: a step, a parameter, and/or a local variable. A step of a sequence may comprise a tree structure of step properties. Each step property may comprise one or more of: a property value, property flags, and/or a property comment. An object may comprise a hierarchy of objects (e.g., a parent object and a child sub-object). Differences between the hierarchy of objects may be detected. Differences may be navigated. Each displayed difference may be characterized as an insertion or a deletion.

Abstract: ELECTRICAL CURRENT GENERATING/DISTRIBUTION SYSTEM FOR ELECTRIC VEHICLES: Would incorporate a roadway transfer system which would work in conjunction with any electrical vehicle that can be provided by any automobile company, and equipped with the components /capability of acquiring power from the roadway system. The roadway power transfer system would be supplied with electrical power from any power provider/power companies. Buy using power transformers to drop voltage to a workable AC or DC range/voltage, 2 strips would be used, with a negative potential being applied to one, and the positive potential being applied to the second strip. To utilize the power made available by the strips the system would incorporate the power made available by material embedded in the tire system, establishing electrical contact to enable the transfer of power from the roadway to the internally connected components to charge the battery pack, and run any AC or DC motor.

Abstract: A lighting fixture having a trough-type reflector and further having planar end reflectors, such fixture also including at least one planar shield parallel to the long axis of the trough-type reflector and having an edge parallel to the aiming axis of the fixture. The shield is undercut to permit light emanations from the lamp to be reflected from the entire trough-type reflector. The shield also includes depending points at the points of contact with the end reflectors, thereby preventing light from being reflected from the end reflectors outside of the shield.

Abstract: A hinged bracket for permitting the swinging away, within limits, of at least one socket to permit easy access to an elongated, doubled-ended bulb for relamping purposes, the relamping apparatus holding the bulb firmly enough to prevent its dropping out of the sockets. The sockets are each spring-loaded and partly biased against the bulb in the open relamp position and firmly biased against the bulb in the position of use. A heat sink is also provided via a sleeve extension on the socket and a mating hump on the door which provides access, when removed, to one of the bulb sockets through relatively small openings in the fixture and the nearby reflector. The swinging away of the socket to one side of these openings provides easy access to the bulb that would not otherwise be possible.

Abstract: A light fixture comprising parabolic reflector segments therein, the lamp being located at the focal point of the segments. One segment has an arc preferably more shallow than the other segment. The window opening is angled preferably at an angle of 60 degrees to the elongate axis of the parabolic segments to provide sharper light cutoff or less spill light from one reflector segment than from the other. A shield positioned parallel to the elongate axis and on the side of the axis within the reflector segment where the cutoff characteristics are the greatest, permits primary reflected light from the lamp, while preventing direct light from the lamp to pass above the shield. The specular underside of the shield enhances light reflection therefrom while the darkened top shield surface blocks secondary reflection above the cutoff angle.

Abstract: An improved light fixture for housing an elongated lamp and method for making same, the fixture having an elongated housing constructed from a continuous rectangular piece of sheet metal having four parallel bends therein forming planar side walls. The planar side walls form flange planes suitable for mating within grooves formed in suitable end pieces for the housing. The closure lens completes the housing. The construction of the elongated housing side walls is such that a reflector sheet when curvedly affixed to the two outermost planar side walls is tangential to the inner three planar side walls, thereby providing a parabolic reflecting surface for a lamp mounted within the reflector sheet. Two end wall reflectors, preferably one of which is directionally adjustable, also reflect luminous flux from the lamp.
