Title: Multiprocessor data processing system
Inventor: KERNS DANIEL R
IPC: G06F9/50
Filed: 1986-11-13
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE          A multiple processor system in which a plurality of co-equal processors share a common memory which includes a data structure for storing machine state information for a plurality of processing tasks (jobs).  The instruction set of each of the processor includes a job processor instruction for storing in the data structure the current of the machine state information of a processing task being executed by a processor at the time such execution has been stopped either because of an interruption thereof or because an allotted time period assigned to a processor for executing that task is over.  The processor can then select another processing task and issue another instruction (JP LOAD) to obtain the machine state information therefor from the data structure to permit such other task to be executed using such machine state information.  A further instruction for permitting a faster load operation can also be issued by a processor when only a portion of the machine state information is required to be loaded.  Other instructions are provided for various purposes useful in the multiple processor context.

Title: Safety floor and sweep with line power
Inventor: GRIFFIN JAMES W
IPC: F16P3/14
Filed: 1987-01-26
Granted: 1991-01-29
Abstract: ABSTRACT     A mobile storage system includes movable carriages that are stopable by solenoid operate mechanical safety brakes.  The solenoids are controlled by an electrical circuit that includes a safety floor and/or a safety sweep.  Actuating the respective safety switches activates the circuit to energize the solenoids for operating the brakes.  The safety floor portion of the circuit is designed to energize the brake as long as a safety floor switch is actuated.          The safety floor circuit portion contains a timing device that holds the solenoid in the energized condition for at least 3 seconds after deactuation of the actuated safety switch, so that a person walking across the floor does not cause the solenoids to chatter.  The safety sweep circuit contains first timing means for deenergizing the solenoid approximately 3 seconds after safety sweep switch actuation.  If the actuated switch remains open after approximately 5 minutes, or if a safety sweep switch fails, an audio alarm sounds.  Both the safety floor and safety sweep portions of the circuit include indicator circuits having light emitting diodes.  The light emitting diodes are placed in appropriate control boxes within the mobile storage system to facilitate maintenance.

Title: Method and apparatus employing offset extraction and companding for digitally encoding and decoding high-fidelity audio signals
Inventor: FREDERIKSEN JEFFREY E
IPC: G11B20/10
Filed: 1987-10-08
Granted: 1992-09-29
Abstract: ABSTRACT    An audio signal is initially represented by a series of high-resolution pulse code modulated (PCM) data.  A lower rate series of representative values are extracted from the initial series of PCM data.  Half of the lower rate is at an intermediate audio frequency so that the lower rate series encodes low frequency components of the audio signal.  The PCM data are adjusted by offsetting in accordance with corresponding representative values and are then converted to a floating-point representation by extracting scale factor or exponents.  The combination of the series of  representative values and the floating-point data provides a rate-compressed representation of the audio signal which is capable of being decoded after transmission or storage to reproduce the audio signal without substantial noise, distortion or los of dynamic range.  The splitting of the audio information between the lower rate series and the adjusted floating-point PCM limits the normally destructive effect that low frequency components of high amplitude have upon high frequency components of relatively low amplitude.  In a preferred embodiment, a common offset is determined for each block by computing the arithmetic mean of the maximum and minimum PCM data values for the block and truncating the result, the PCM data are adjusted by subtracting their corresponding common offsets, and a common exponent is determined for the block of adjusted PCM     data.  For encoding high-fidelity audio, preferably the audio signal is initially represented by a series of 16-bit PCM samples at a rate of at least 36 kilohertz, the block size is chosen to be 16 audio samples, and the encoded and compressed data for each block includes a 160 bit frame consisting of an 8-bit block offset, a 3-bit block exponent, a 5-bit error correction code, and sixteen floating-point values each including eight data bits and one parity bit.  This format permits 9 stereo audio channels and frame synchronization to be readily transmitted over a conventional video channel.

Title: Method and apparatus for analyzing different sulphur forms
Inventor: MOON KWANG S
IPC: G01N21/3504
Filed: 1987-11-06
Granted: 1993-04-27
Abstract: Abstract A method and apparatus are described for quantitatively determining the different forms of sulphur present in a solid matrix, e.g. coal.  The novel method comprises intimately mixing finely divided coal with a finely divided solid diluent material, e.g. silica, which is inert to sulphur under reaction conditions.  This mixed sample is then burned within a confined combustion zone at a predetermined ele-vated temperature and the combustion gases from the combus-tion chamber are continuously removed.  These gases are passed through an infrared analyzer which continuously moni-tors the intensity of the infrared spectra for sulphur oxy-compounds in the combustion gases.  The infrared intensity is measured as a function of evolution time of sulphur oxy-compound from the sample to obtain peaks in an infrared intensity-time pattern indicative of different forms of sulphur.

Granted: 1992-08-04
Abstract: Abstract A method of and an arrangement for leading a web on to a desired wire in a paper machine or the like.  When the web moves between two wires,  it is transferred on to one wire after the wires have moved in parallel over a distance with the web therebetween making contact with both wires.  The transfer takes place when the wires start to move in different direc-tions by sucking the web on to one of the wires by a vacuum acting through said wire. For improving the de-tachment of the web from the other wire, the direction of travel of the wire is changed abruptly at the part-ing point of the wires by leading it along a suction box  comprising a cover piece formed by cleats and ar-ranged to form an angle in such a way that the point of the angle projects towards the wire. When the wire moves along the cleats of the cover piece of the suc-tion box, its direction of travel is abruptly changed at the point line of the angle, whereby the web is de-tached from the other wire completely in a moment.
