Abstract: A liquid pitcher has an integral mixer system/stirrer assembly for mixing liquids directly in the pitcher without shaking or spilling. The pitcher includes a pitcher container and a cover. The mixer itself includes one or more mixing elements mounted on a shaft that extends through an opening in the cover, on the one hand, to position and to permit positioning of the mixing element in the pitcher and, on the other hand, to help fix the shaft at a location relative to the cover and pitcher when the cover is properly placed on the pitcher. Importantly, a handle attached to the shaft outside the pitcher, when the cover is installed thereon, cooperates with the opening that secures the shaft in position and with a mating rim about the cover to guide the handle during such rotation to assure proper positioning of the shaft and mixing element and to avoid excessive wearing of various portions of the assembly during mixing operation.

The feeders are adjustably secured both pivotally to and longitudinally along their respective cross bars and each includes a plurality of stacked conductive leaves which are pressure welded together and to contact and reinforcing plates at their ends.

Abstract: An apparatus adapted to be positioned downstream of a foam extrusion die in an environmental control or vacuum chamber for remote monitoring of the thickness and profile of foam boards, planks and like extrudates soon after the extrudate exits the die and takes its final shape, is characterized by opposed, relatively narrow shoes on opposite sides of the extrudate path and respective carriages therefor which together are movable transversely with respect to the extrudate path by respective worms and translating nuts and a common worm drive. One shoe is operative to support the bottom surface of the extrudate in a predetermined position while the other shoe rides on the extrudate and is position monitored by a transducer operative then to provide an output signal representative of the spacing between the shoes, and thus the thickness of the extrudate passing between the shoes, to remote monitoring circuitry located outside of the vacuum chamber.

Abstract: A tire press and loader includes a tire chuck supporting, horizontal elevator frame which is vertically movable and maintained horizontal under normal operating conditions by drives connected to respective opposite ends of the frame. The loader also includes a safety device operative to cause canting of the frame from such horizontal position upon failure of one of the drives and a control responsive to such canting to render the loader drives inoperative and further to interrupt automatic operation of the press until the fault causing such failure is corrected. The safety device includes holding devices at opposite ends of the horizontal frame which yield to downward driving movement of such ends by respective drives. The holding devices are characterized by flexible elements trained over sprockets connected by slip clutches to a common safety shaft which may rotate in only one direction corresponding to upward movement of the horizontal frame by reason of a one-way clutch or the like.

Abstract: A garage door weather seal for use on a garage having a door with a planar outside surface and a door frame including a surface normal to the plane of the garage door when closed. The seal comprises a main body portion which lies in a plane extending at an angle to both the door and door frame surfaces when installed. Sealing lips integrally molded to opposite edges of the main body portion form a weather-tight seal with both the surface of the garage door and the surface of the door frame. An L-shape leg structure connected with the main body portion serves to position the weather seal with respect to the door frame. The leg structure has two legs which deflect slightly to grip two surfaces of the door frame, one the above-mentioned surface and another normal thereto. One of the legs may have apertures for fasteners to hold the seal in place.

Abstract: The frequency of the AC signal used to detect the integrity or lack of same in a conveyor belt is reduced to be in the 25 KHz. to about less than 200 KHz. and most preferably in the 50 KHz. to 100 KHz. frequency range. When such AC signals are capacitively coupled to antennas carried by a conveyor belt past a rip detector station, the ratio of the magnitude of such signal relative to that of the cross coupled noise, in particular, and other electrical noise in general is significantly increased. The invention relates to an apparatus and method in which signals in such frequency range are used.
