20110297904 | HUMIDITY RESPONSIVE MATERIALS AND SYSTEMS AND METHODS USING HUMIDITY RESPONSIVE MATERIALS - The invention relates to silk or other materials formed to have predetermined contraction/relaxation characteristics, wherein the contraction/relaxation characteristics are initiated by exposure thereof to predetermined humidity characteristics in the adjacent atmosphere. The materials may comprise a single silk fiber, a bundle of fibers of a predetermined size or diameter, a meshwork of fibers forming a predetermined configuration such as one or more sheets, bundles or other bodies. In this manner, the material can be scaled across a size range of any desired magnitude to produce predetermined force and/or displacement characteristics in association therewith. | 12-08-2011 |
20150076429 | HOIST SAFETY LOCK MECHANISM - A hoist safety lock mechanism includes a pair of pawls formed on terminal ends of each corner of a pallet support structure. The pawls are biased outward to an extended position and include a lower support surface adapted to rest on a support surface. The pawls may be pivotally deflected downward (but not upward) due to impact on a top surface of the pawl. Each pawl is configured to be received within a respective parallel column of slots formed on inwardly-facing sides of the vertical posts forming the lifting frame of the hoist. The slots within each column are vertically offset and separated by separators which can vertically deflect the pawls. Because the slots are vertically offset, and because each terminal end includes a pair of pawls, there is always at least one pawl engaged within the slot even if the other of the pair is deflected by contact with a separator. Thus, any failure of the hoist will cause the pallet support structure to only fall to the next lower separator before the pawl catches it. | 03-19-2015 |

SINGLE THROW LEVER AND BAR | 3 |
20080251773 | Cam jack - A cam jack has an L-shaped unitary body portion, with a lever arm and a cam finger and an elbow formed between them. A pair of rollers are supported on an axle that is affixed at the elbow. A socket or fitting formed at the proximal end of the lever arm allows a lever handle to be removably attached. The cam finger is oriented at a near right angle to the lever arm. When the lever arm is disposed vertically, the cam finger can be positioned under the item to be lifted, and then as the lever arm is rocked downward as lobe tip of the cam finger urges the item upward. When the lever arm is positioned horizontally against the floor, the lobe tip is displaced outward past the axle of the rollers, so there is an over the center action holding the cam jack stable while supporting the load. An additional set of rollers can be present so the device may be used as a dolly. | 10-16-2008 |
