Abstract: A clamp structure includes a frame defining an aperture through which an elongate member extends. A shoe is fitted in a channel of the elongate member and is of external cross-section substantially complementary to the cross-sectional configuration of the channel. A mechanism forces the shoe into the channel and firmly presses the elongate member against the frame.

Abstract: A machine for making ice cream bars is provided with a receptacle for holding a refrigerant, preferably an ice and brine bath, a lower lid movably mountable over the receptacle, and an upper lid mountable over the lower lid, the lower and upper lids rotatable together about a vertical axis. The machine further includes four containers for receiving and holding an ice cream bar mix, the containers configured to be coupled to the upper lid and the lower lid with a portion of the container immerged in the bath. A user can turn a handle on the receptacle to rotate the lids, and thus the containers relative to the bath in order to promote freezing of the ice cream mix into an ice cream bar.

Abstract: A level comprises a frame defining first and second parallel channels and first and second rails fitted slidingly in the first and second channels respectively. The level is adjustable in length by sliding the rails in the respective channels of the frame.

Abstract: Specific-point signage structure for use in an interior building space of the style generally divided and organized by low-wall cubicle panels—in particular where such a point can be approached and viewed from a large number of different angularly displaced locations. The signage structure is configured in such a fashion that it presents a viewing surface, such as a curved, or otherwise angularly differentiated, viewing surface, which readily conveys information to viewers distributed at widely different angular locations relative to the position of the structure.
