Abstract: An automated storage system transports data cartridges between a storage device and a plurality of storage cells via a picker assembly. The storage cells are formed of one or more removable magazines. The picker assembly accurately locates each data cartridge within a storage cell by first establishing a zero position reference and locating a home position relatively therefrom. The home position is a predetermined point on each magazine. An infrared detector and infrared sensor are situated on the picker assembly for precisely locating the home position. Each cartridge is known to be located within a predetermined tachometer count range from the home position. The detector/sensor is used to precisely locate each cartridge. The precise tachometer position is stored and the cartridge is returned to the known location. As a result, tolerance accumulation effects are eliminated in the system.

Abstract: A unitary, combined-purpose, functional shield--in the shape of a hollow, generally conically shaped apertured cap for a telescope lens is used with a telescope in a straight or inverted fashion to achieve protection from dew for a telescope in general and a lens thereof in particular, while at the same time assisting in the focusing of light.

Abstract: This disclosure pertains to a shoe construction in which a sack is disposed within a cavity formed between the inner and outer sole of a shoe. An air valve may extend through the side walls of the cavity permitting the sack to be filled with a fluid. Selective portions of the insole are fixedly secured with the abutting surface of the sack so as to provide stiffer foot supporting areas thereat than adjacent unsecured areas.

Abstract: When a predetermined amount of separated sludge has accumulated in the peripheral part of the centrifuge rotor, a sensing device automatically opens outlets for the discharge of sludge. To provide substantially constant time intervals between consecutive openings of these sludge outlets, the feed rate to the centrifuge is automatically decreased in response to a shortening of these time intervals and automatically increased in response to a lengthening of these time intervals.
