Abstract: My present invention relates to a barbeque grill and more specifically to a two-tiered barbeque grill system which uses water troughs strategically placed below the cooking surface so as to catch all of the melted fats thus preventing the grease from coming into direct contact with the hot coals below and causing undesirable flare-ups. Meats barbequed on conventional grills over charcoal have always resulted in troublesome flare-ups which burn and char the meat. These flare-ups have always proved difficult to contain, control, or eliminate. It is the primary object of my invention to provide a barbeque grill system that is capable of eliminating these undesirable flare-ups.

In addition, heated air can be provided for drying the cleaned shoes.

Abstract: A drive system for capstan driven magnetic tape rolls in which a power belt is trained around a drive wheel and a pair of belt guides. The belt guides are closely spaced relative to the capstan so that the back side of the belt transfers power to the capstan roller while the inner surface of the belt contacts the drive wheel and belt guides. The angular spacing of the belt guides relative to the capstan roller is such that the angle between the axial centers of the belt guides with respect to the axial center of the capstan roller is as large as practical, thereby increasing the frictional surface transferring power from the drive wheel to the capstan roller.

Abstract: A rotor and stator mixing system has mixing-chamber recesses in the outer periphery of the rotor and inner periphery of the stator which are generally similar, arrayed in peripheral and axial rows and are mutually axially offset. The guide radius R of the semicircular ends of each elongated recess is also the trough radius thereof and the trough depth is less than this guide radius. The length L of the mixing chambers is three to four times the guide radius, the web width between the recesses of each circumferential row is less than half the guide radius and the shear gap width W is so selected that the shear velocity which is realized is sufficient for effective mixing by a shear action.

Abstract: A web feeding apparatus according to the present invention feeds in one direction a thermal transfer ribbon as a web with low transverse rigidity clamped between a platen roller and a recording head having a predetermined printing range. The web feeding apparatus comprises support members disposed on the lower-course side of the platen roller with respect to one direction and adapted to increase tension on the thermal transfer ribbon at each side edge portion thereof along one direction.

Abstract: A novel vehicle bumper-storage compartment wherein the presence of the storage facility is totally hidden so as to provide the sole appearance of a bumper, but with added capability of storing and dispensing sheet material from within the storage compartment for such uses as covering a truck bed or providing adjacent emergency shelter or tenting and the like.

Abstract: There is provided a beverage pitcher in which is mounted a stirrer device for stirring or agitating the contents of the pitcher. The stirrer device includes a plurality of axially spaced vane lobes which are substantially equiangularly spaced about a longitudinal axis. The maximum radial extent of the vane lobes from the lognitudinal axis decreases in the direction from the lower end to the upper end of the plurality of vane lobes, so that during operative rotation of the vane lobes the stirring or agitating effect is at a minimum at the maximum upper level of the contents of the pitcher where only a minimum stirring or agitating effect is required and where substantial stirring or agitation is undesirable.

Abstract: A tape support which provides several different functions in a reel-to-reel tape drive is disclosed. The tape support provides means for sensing tension in the tape, buffers or decouples the tape at the magnetic head from any perturbations arising at the take-up reel, and reliably guides the tape along the tape path. The tape travels along an arcuate surface of the tape support on an air bearing. A port in the arcuate surface senses pressure between the tape and the arcuate surface. This pressure is communicated to a transducer which provides an output representing the tension on the tape. Flanges on the ends of the tape support provide guiding of the tape over the air bearing and also provide venting of the air bearing to prevent tape vibration. A purge line expels a gaseous medium out of the sense port thereby keeping the sense port clear of contaminants.

Abstract: The present disclosure describes a portable bench which finds particular application in the automotive field. The bench is comprised of a main body for supporting a pair of opposed drawers in sliding relationship to one another. When the drawers are in a closed position, they are concealed within the main body. A support assembly is removably attached to the front of each of the drawers. In use, the bench is oriented at a right angle to the longitudinal axis of the vehicle. The drawers are slid outward from the main body to permit the support assemblies to engage the respective opposite fenders of the vehicle. Tools, parts and related materials may be rested upon the main body which can be slid from one extremity of the bench to the other. Items placed in the drawers during use of the bench may be temporarily stored therein when the bench is removed from the vehicle and the drawers closed.

Abstract: Apparatus for controlling the alignment, in a lateral (cross-track) direction, of a web moving along a path to minimize lateral deviation between successive discrete areas of such web. The apparatus includes a steering roller for supporting the web for movement along such path. The steering roller is rotatable about an axis perpendicular to the plane of the span of the web approaching the steering roller. As the web moves along the path, the lateral position of a marginal edge of the web relative to a reference plane is sensed. When such lateral edge position is at either of two spaced predetermined locations relative to such reference plane, signals indicative of the presence of such edge at such locations are produced.

Abstract: A pneumatic monitoring system for a magnetic tape drive includes a single sensor which includes a differential pressure transducer. Points in the tape drive to which vacuum is applied are coupled to one side of the sensor and points in the tape drive to which pressure is applied are coupled to the other side of the detector. The sensor produces an analog voltage representing the state of the pneumatic system. It is digitized and applied to a microprocessor which compares the sensor voltage to present ranges for calibrated conditions of the tape drive. If the sensed voltage is outside of these ranges, error conditions are indicated.
