Abstract: A compartment storage container for use in a collective objects management system with remote location of compartments containing sought objects. Each compartment has an address decoder with a unique address electrically connected to an electrical input connector which supplies compartment search signals to the container. Each compartment has an LED indicator which is activated when a compartment search signal specifies a compartment address which matches the address of an address decoder in the container. Each container has an electrical output connector which can be connected to the electrical input connector of another container so that several containers can be connected to one another. Each container can be removably installed in a cabinet drawer and electrically connected to conductive support rails in the drawer to communicate with a cabinet based collective objects management system.

Abstract: A collective objects management system for objects such as documents contained in file folders in drawers of file cabinets. Each file folder has an electrical circuit with a visible indicator mounted on the file folder. Each folder circuit has a pair of crystals which are responsive to R.F. signals of specific frequencies, the frequencies of each pair being different for each folder circuit. An associated computer operates an R.F. signal generator to produce R.F. signals at the frequencies of the particular folder circuit of the file folder selected for retrieval. To aid the user, each file drawer has a visible indicator mounted on the front panel, the panel indicator being illuminated when the sought folder is contained in that drawer. The invention can be applied to a wide variety of collective objects management systems, such as supermarkets, automobile parts distributors, and various manufacturing operations.

Abstract: The address of an operand in computer main memory is computed by a system which utilizes a base memory frame address in combination with a displacement value, indicative of the position in the frame of the operand relative to the base memory frame address, and information relating to the length of the operand to supply system hardware with the necessary information to enable a fetch of the operand from main memory. This system has the capability to compute addresses for multi-byte word operands within a single firmware clock cycle.

Abstract: An axially symmetrical, self-pressured air system has a substantially sealed enclosure for high speed rotating discs. Air admission to the enclosure is located such that pressures throughout the enclosure minimize the entrance of contaminants. A tangentially positioned chamber can be symmetrically arranged about a tangent in the cylindrical wall of the enclosure. Filters adjacent both the axial receiving means and the tangential chamber rid the enclosure of disc damaging impurities.
