Abstract: A sliding window and door lock including: A housing, where the housing is attached to at least one of a window sill and the floor next to a sliding door; a pivoting latch and a pivot, where the pivot attaches the pivoting latch to the housing, where the pivot is located farther along the path of travel of the at least one of a sliding window and sliding door when the housing is mounted to the at least one of a window sill and the floor, wherein the pivoting latch is adapted to pivot from being flush with the edge of the housing into the path of travel of the at least one of a sliding window and a sliding door, wherein the edge of the pivoting latch interfaces with the at least one of a sliding window and a sliding door, wherein the force of the at least one of a sliding window and sliding door would be obstructed by the pivoting latch being forced into the pivot.

Abstract: A method of detecting a presence of an analyte in a sample. The method includes selecting an aptamer selective to the analyte and binding the aptamer to a nanoparticle. The nanoparticles having a free state are perceived as a first color and an aggregate state are perceived as a second color. The sample is introduced to the nanoparticle-bound aptamers, and aggregation of the nanoparticles is promoted. A colorimetric change is analyzed, wherein the aggregate state of the nanoparticles is achieved in the presence of the analyte in the sample.

Abstract: Apparatus is provided for facilitating the loading of a hollow cylindrical drum, for example, an image-recording drum in an electrostatographic printer or the like, onto a rotatably driven drum axle having a free end extending outwardly in a cantilever manner from a support frame and having a longitudinally-extending axis of rotation. According to a preferred embodiment, such apparatus generally comprises a plurality of slide mechanisms disposed at equal distances from each other and from the intended axis of drum rotation. Each of the slide mechanisms comprises a pair of elongated slide members extending parallel to said axis of rotation, one of the slide members of each of each pair being rigidly supported by said drum axle, and the other slide members of each pair being slidably mounted on the rigidly supported slide members for movement parallel to the drum axis.
