Abstract: An embodiment of a storage device for medical products includes a cabinet defining an enclosure having a plurality of compartments. In addition, the storage device includes a plurality of storage containers, each storage container configured to be inserted into a corresponding one of the plurality of compartments. Further, the storage device includes an actuation assembly including a plurality of arms that are configured to engage the plurality of storage containers so as to secure the plurality of storage containers in the plurality of compartments. Still further, the storage device includes a release mechanism that is configured to simultaneously actuate each of the plurality of arms to release the plurality of storage containers from the plurality of compartments.

Abstract: A method for removing heavy metals or radionuclides from an aqueous solution comprising contacting the aqueous solution with an ion exchange material selected from a solid ion exchange material, a liquid ion exchange material, or mixtures thereof, wherein the ion exchange material is prepared by the process comprising: contacting clinoptilolite with an alkaline solution at a temperature of about 85° C. to about 300° C. and for a sufficient time to form a treated slurry comprising a solid fraction and a liquid fraction, and optionally separating the solid fraction from the treated slurry and washing the solid fraction to produce the solid ion exchange material; and optionally recovering the liquid fraction of the treated slurry to produce the liquid ion exchange material. A process for producing the above ion exchange materials useful for removing heavy metals or radionuclides from an aqueous solution, and the solid and liquid ion exchange materials produced by the process.

Abstract: In a multiprocessor computer system, an access request and an access grant register is provided for storing an access request and an access grant semaphore for each shared resource. The access request and grant semaphores having a number of access request and grant bits assigned to the processors. Additionally, circuits are provided for each access request register for setting/clearing individual access request bits, and simultaneous reading of all access request bits of the stored access request semaphore. Furthermore, coordinated request and grant masks that reflect the relative access priorities of the processors are provided for the processors to use in conjunction with the current settings of the access request and grant semaphores to determine whether a shared resource is granted to a lower priority processor and whether a shared resource is being requested by a higher priority processor.

Abstract: An oscillator circuit for outputting clock signals of varying frequency which reduces interference caused by electromagnetic radiation from clock control systems includes a resistor-capacitor network for outputting a delay signal which delays the generation of clock signals by the oscillator by a predetermined time period and modulating the delay signal with an analog signal enabling the oscillator to output clock signals of varying frequency.

Abstract: Arbitration as provided in two separate levels, first between two signals that may contend for access to a system resource, such as a memory, and second between the winner of the first arbitration and another source, such as a refresh signal timer, that must have access to the system resource periodically and independently of requests for access from the other signals. The winning signal of the first arbitration is not continuous but is divided into intervals, and the refresh timer gains control of the second arbitration at the end of each interval of control by the winning signal from the first arbitration.

Abstract: A memory addressing system includes an addressable memory provided with error checking and correction (ECC) circuits which include output latches adapted to latch corrected data read from the memory. An applied memory address is compared in a comparator with a previous memory address stored in an address latch and if a match is detected, a match signal is effective to inhibit the occurrence of the next memory cycle and to activate a decoder coupled to the output of the ECC circuits to cause transfer to the system bus of selected data from the ECC latches. If no match is detected, a memory cycle is initiated to access the desired data in the memory. A high-speed memory operation is thus achieved utilizing simple circuitry.
