Abstract: A dolly for lifting one end of a long open web steel joist or truss and for then conveying the joist to and fro along a steel structural beam member having a horizontally disposed web which normally restingly supports the joist. The dolly includes a main body which carries an axle having a wheel journaled thereto for runningly and ridingly engaging the beam member as the joist is manually maneuvered into its optimum position. A lever or handle is fixedly attached to the main body and coacts with the wheel (which acts as a fulcrum) to lift the heavy joist as the handle is manually urged downwardly. Various embodiments of structure for engaging and supporting two different type joists are disclosed herewith.

Abstract: A carton, e.g., a straight tuck style or sealable end style, intended to minimize pilferage, particularly at the retail outlet, of the product, contained therein. The carton includes a window opening which is enclosed by a transparent heat-shrinkable membrane having peripheral segments thereof secured to predetermined portions of the sidewalls, the dust flaps, and the closure flaps. The carton may optionally include shelf structure for supporting the product. The membrane structure restrains the product in an optimum orientation subsequent to the membrane being shrunk. The dust flaps define in part prominent spaces at either end of the carton which assure that the membrane is not pinched when assembling the carton, therefore, the membrane is free to totally pull away from the window as it is shrunk. Blanks for producing the above-described cartons are also disclosed herewith.

Abstract: A toy which may be spun about on a flat surface and which is intended to be activated by a sharp pointed rod or pencil. The toy is characterized by a disklike body having a circular rim which is disposed on the bottom thereof and runningly engages the flat surface as the toy is caused to be activated. An upwardly directed concentrically disposed socket is included for guidingly receiving the sharp end of the rod. A downwardly directed intermittent force suitably applied to the rod causes the toy to wobble about indefinitely on the flat surface, i.e., subsequent to the toy's first having been manually started to wobble. Weight may be added to the toy adjacent the periphery thereof to facilitate the wobble spinning action.

Abstract: A filter device intended to be fitted into a deep fat fryer to filter foreign particles from the hot liquid fat used in the cooking process. The device includes a pan that contains the liquid fat in which the food to be cooked is placed. The bottom of the pan is provided with an opening through which the fat passes outwardly as the pan is lifted from the deep fat fryer. Nestled within one embodiment of the pan and extending over at least a portion of the bottom thereof is a unit which establishes in part at least one channel through which also passes the fat as the pan is lifted. Another embodiment has the unit depending from the bottom of the pan. In either embodiment, a filter, having progressively smaller sized holes, is disposed within the channel for capturing and separating ever decreasing smaller size foreign particles from the fat.

Abstract: A prosthesis for replacing a defective stapes of the middle ear. A piston is provided for transmitting sound vibrations from the incus to the oval window of the middle ear. A clamp is securely attached to the piston for anchoring the piston to the incus. The clamp is capable of being easily bent to securely grasp the incus and is capable of maintaining that bent shape after the force causing it to be bent is removed.
