Abstract: ABSTRACT OF THE DISCLOSURE      An optical matrix switch comprises 1  x M/2 optical switch means of N in number, optical switch groups of M/2 in number, and N/2 x 1 optical switch means of 11 in number, where N is a number of inputs, and M is a number of outputs. Each of the 1 x M/2 optical switch means includes a predetermined number of optical switch elements each having a function to switch an optical signal between inputs and outputs in accordance with an applied electric field, and has one input and outputs of M/2 in number. The predetermined number is decided dependent on an equation of log2 M/2. Each of the optical switch groups includes optical switch elements of M/2 in number arranged transversely, and each of the N/2 x 1 optical switch means includes a predetermined number of optical switch elements. The predetermined number  is decided dependent on an equation of log2N/2.  A longitudinal length of the optical  matrix switch is approximately (log2M/2 + 1 + log2N/2 times  a length of an optical switch element.          Therefore, the optical matrix switch is made smaller in the longitudinal direction.

Title: Hydraulic well penetration apparatus and method
Inventor: SCHELLSTEDE HERMAN J
IPC: E21B43/00
Filed: 1988-04-22
Granted: 1991-01-02
Abstract: ABSTRACT OF THE DISCLOSURE     A well casing penetrator includes an elongated housing enclosing an outwardly movable hydraulic cylinder driven punch fur cutting an opening in a casing.  A high pressure liquid jet nozzle is mounted on the end of a hose which moves outwardly through an axial bore in the punch when extended through the casing to cut a radially extending opening in the surrounding earth.   The punch includes arcuately curved longitudinal slots along opposite sides which cause tabs to be bent back along opposite sides of the opening cut in the casing to prevent dislodging of any portion of the casing from the casing as a consequence of the operation of the punch.  A spool piston is connected to a single accumulator that is pressurized to urge the spool piston toward a first position in which work fluid controlled by the spool piston retracts the hydraulic punch cylinder and a hose drive cylinder for moving the hose in the punch.   When the pressure is increased the accumulator is overcome and the punch cylinder and the hose drive cylinder are activated along with apparatus supplying work fluid to the hose to initiate a penetration operation.   The parts return to their original retracted position upon lowering of the work pressure.

La semelle inclut des logements internes 11, en nombre égal à celui des sorties de contact 12, qui assurent à la fois la protection et le guidage de celles-ci. Une pression exercée sur le boîtier perpendiculairement au circuit imprimé 4 détermine un coulissement relatif des pièces 1 et 3 provoquant l'affleurement puis le dépassant à la longueur prédéterminée des sorties de contact 12.

Abstract: ABSTRACT        A gaseous mixture containing chlorine, carbon dioxide and non-condensable gas is compressed and cooled to separate it into a residual gas formed principally of a major portion of the non-condensable gas and a condensate formed primarily of chlorine.  The condensate is fed to a stripping column to desorb carbon dioxide and a minor portion of the non-condensable gas dissolved in the condensate.  The stripped gas formed primarily of chlorine and carbon dioxide may be treated further.  Namely,  the stripped gas is mixed with the residual gas.  At least a portion of the mixed gas is fed into an absorption column, whereby a major portion of remaining chlorine is absorbed to lower the chlorine content.  Removal of chlorine from such a gaseous mixture or an off-gas from the above process can be achieved by washing it with an aqueous solution or suspension containing an alkali metal sulfite and/or an alkaline earth metal sulfite while controlling the pH of the solution or suspension within a range of 1.9-6.3.

Abstract: A whole blood glucose test strip for measuring glucose in an unmeasured whole blood sample is described, the test strip being adapted for use in a reflectance reading apparatus capable of measuring reflectance at two difference wavelengths.  The test strip comprises a porous, hydrophilic matrix having a sample receiving surface adapted to receive the whole blood sample on one side of the matrix and a testing surface from which diffuse reflected light is measurable from the other side of the matrix, wherein the testing surface is opposite to the sample receiving surface.  The matrix is substantially reflective in the absence of applied sample, and contains openings of a size sufficient to allow the flow of at least a portion of the blood sample through the matrix from the sample receiving surface to the testing surface.  The matrix comprises glucose oxidase, peroxidase, and a dye precursor for chemically reacting with glucose to create a change in reflectance in the presence of optically visible hemoglobin observable from the testing surface which change is indicative of the concentration of glucose present in the sample.  The dye precursor comprises 3-dimethylaminobenzoic acid and 3-methyl-2-benzothiazolinone hydrazone hydrochloride.

Title: On-board tire pressure indicating system performing temperature-compensated pressure measurement, and pressure measurement circuitry thereof
Inventor: BOCK DITMAR H
IPC: B60C23/04
Filed: 1989-04-27
Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE    A reliable indication of temperature-compensated pressure  is provided from each of  the wheels  of  a vehicle  to  an  operator  within  the  vehicle.    A piezoresistive  transducer  bridge  is  supplied  by  a constant current source in one embodiment,  and by a voltage of constant amplitude in another embodiment.          Voltage to the bridge is reversed on a periodic basis.          The use of constant current enables compensation for temperature-induced drift in transducer bridge output.   The use of constant voltage enables compensation for ambient temperature,  and provides an absolute, rather than a relative indication of pressure or "flatness" within the tire.   Voltage polarity reversal permits compensation of amplifier offset voltage.   Energy is transmitted to and from the wheel by means of a tuned circuit which is excited by a primary coil when the vehicle s  engine  is  running.   The  secondary  coil mounted on the wheel may be either short-circuited or selectively opened and closed to alter the operation of the primary coil, thus providing an indication of tire pressure, that indication being detected and processed by suitable microcomputer circuitry which may exist on board the vehicle.  Most of the active circuit elements of  the  invention  may  be  implemented  in  a  single monolithic integrated circuit, which can be attached to a tire valve.

Abstract: SINGLE-KEYED INDEXED FILE FOR      TP QUEUE REPOSITORY                        ABSTRACT      A task queue is structured as a single-keyed indexed file in which the key has a most significant portion indicating a priority level and a less significant portion that is ordered with the loading of the tasks into the queue.  For any given task record in the queue, the less significant portion of the key is determinable from a respective task identifier.  Preferably the less significant portion of the key is a "time stamp" including the current date when the task was created and a representation of the data processor's internal 24 hour time clock, and a task identification number is formed by appending a node number to the time stamp in the event that the system has multiple processors capable of creating different tasks at the same time.  This format of the single key causes an internal ordering of the records in the queue that is sequential with respect to the less significant portion of the key within blocks of records having the same priority.  Therefore, due to the relationship between the key and the task identification number for each task record in the queue, it is possible to quickly search for the record having a requested task identification number.  Conventional memory management facilities for accessing key-indexed files can be used for searching the queue.  In this case the queue is searched by random or "key next" access to repeatedly step through the possible priority levels until a record having a matching key is found or the end of file is reached.  When a record having a matching key is found, the requested task identification number is compared to the identification field of the record.  If there is a match, the desired record has been found.  If not, then searching continues by sequential access until there is a match of the identification numbers or until the keys no longer match.
