Abstract: BIOLOGICAL TEST DEVICE FOR STEAM STERILIZERS  Abstract of the Disclosure A disposable package is adapted to simulate the steam permeability and other qualities of the linen pack previously used to test the functioning of a steam sterilizer using a biological test device.  The biological test device comprises spores on an appropriate carrier, either in a self-contained biological device or as a spore strip.  The biological test device is placed within applicant's specially constructed package and the package is placed within the sterilizer, which is then cycled through a conventional sterilization cycle.  During the sterilization cycle, applicant's package simulates the standard sterilizer linen pack previously used for such tests.  After the sterilization cycle, sterility of the spore preparation is evaluated by incubating the spores in a culture medium to determine whether the spore population has been adequately destroyed.

Title: Plural magnetic disk assembly
Inventor: JONES DAVID E
IPC: G11B23/033
Filed: 1987-04-21
Granted: 1993-08-17
Abstract: ABSTRACT OF THE INVENTION         A device and process for stabilizing two coaxially joined flexible magnetic disks is disclosed.  Two or more flexible magnetic disks are coaxially joined by a coaxially located spacer.  One of the disks is juxtaposed to and rotated against a flat stable Bernoulli surface.  A second disk space by the spacer from the first disk contains centrally located perforations into which air can flow.  When the disks are rotated at high speeds air flows into the perforations and radially out from between the disks, thus forming an air cushion or air bearing between the disks.  The apparatus and process thus provides two floppy disks stabilized by a single Bernoulli surface.

Abstract: Abstract of the Disclosure:     In an encoder comprising a pulse producing unit for producing an excitation pulse sequence in response to a speech signal having electric power level, a detecting unit detects the electric power level in response to the speech signal and produces a detection signal.  Responsive to the excitation pulse sequence and the detection signal, a processing unit processes the excitation pulse sequence in accordance with the detection signal and produces a processed signal.          Preferably, the processing unit should comprise a classifying unit for classifying the detection signal into a plurality of classes in accordance with the electric power level, an extractor for extracting a plurality of excitation pulses in accordance with the classes to produce extracted excitation pulses, and a quantizing unit for quantizing amplitudes and locations of the extracted excitation pulses into quantized amplitudes and quantized locations.  The quantized amplitudes and locations are represented by bits of a first and a second bit number, respectively, which numbers should be determined with a product of the number of the extracted excitation pulses and a sum of the first and the second bit numbers kept at a predetermined number.  Alternatively, the detecting unit may detect the electric power level in response to the excitation pulse sequence.
