Abstract: @ A method of detecting and correcting errors in digital audio signals comprises assembling digital data words each of which corresponds to a digital audio signal representing an analog audio sample into units of six data words, assembling with each unit six redundant words derived by exclusive-OR operations on the data word in each row and each column of the unit, assembling the data words and redundant words into sub-blocks and adding cyclic redundancy check code words to the sub-block, recording and reproducing each sub-block, after reproduction using the code words of each sub-block to add error flags to each word in the sub-block, re-forming the units and assembling with each reproduced unit syndromes derived by exclusive-OR operations on the data words and redundant words in each row in each column of the unit, comparing the syndromes and correcting the error flags in dependence on this comparison, deriving horizontal syndromes by exclusive-OR operations on the data words and redundant words in each row of the reproduced unit and where there is only a single word in a row flagged as being in error, correcting that error word using the horizontal syndrome, and deriving vertical syndromes by exclusive-OR operations on the data words and the redundant word in each column of the reproduced unit and where there is only a single word in that column in error, correcting that error word using the vertical syndrome.

Title: Latency removal
Inventor: PROUGH JAMES ROBERT
IPC: D21D5/00
Filed: 1985-05-08
Granted: 1988-12-22
Abstract: @ The latency of mechanical pulp is removed in a quick and simple manner. After refining of comminuted cellulosic material in a refiner (12) to produce mechanical pulp, the pulp is fluidized at a consistency of about 5-30% to remove latent properties. For instance, the pulp is diluted (if necessary) to a consistency of between about 5-30% (preferably 8-15%), and the pulp is then merely pumped to a further treatment stage. Pumping is effected utilizing a centrifugal pump (15) which fluidizes the pulp, the fluidization imparting sufficient energy to the pulp to remove the latent properties. The pulp may be pumped to a storage stage (23) prior to passage to a screening stage (21), and can be pumped in a direct (non-return) path (20) from the pump to the screening stage. If desired or necessary, a portion of the pumped pulp can be recirculated (in line 26, 26') and pumped again to ensure that sufficient energy is imparted thereto to effect latency removal.

Abstract: In a data processor having a paging system, a list (48) is kept of the disk seek time when a page of information is brought into processor memory from a disk storage device. The average seek time for the pages in memory is calculated and is compared with a reference value of seek time. When the average reaches the reference, the pages in memory are reordered on the disk. This reordering takes place as the pages are bumped from memory in the normal process of paging, and the pages are relocated on the disk tracks in the physical order in which the pages were originally brought into memory. If approximately the same pages are fetched again in approximately the same sequence, the read-write head of the disk drive will be moved a shorter distance between successive disk accesses with reduced backtracking. The invention is particularly intended for a data processor of intermediate size that is large enough to use a paging system but small enough to use a disk drive that has an appreciable seek time.

Abstract: A high density fermentation process for high yield production of a protein having bovine growth hormone activity by transformant E. coli strains is described. The process employs transformant strains of E. coli containing a gene coding for a protein having bovine growth hormone activity under the control of a bacteriophage lambda promoter-operator and a gene coding for the λc1857 temperature-sensitive repressor protein. In the initial growth period, the level of dissolved oxygen in the fermentation medium is maintained at about 20% to 60% saturation and the temperature of the medium is maitained at a temperature at which the λc1857 repressor protein is active. Production of the desired protein is then induced by raising the temperature of the medium to at least about 42°C. The temperature is then reduced to about 38°C to 41 °C to optimize cell growth for the remainder of the induction period, during which the level of dissolved oxygen in the medium is maintained at about 10% to 40% saturation, and the protein having bovine growth hormone activity thus produced is recovered from the transformant cells.

Abstract: A driving belt has a textile supporting element composed of multi-functional threads or yarns which contain plastic fibers of high breaking strength and heat-resistant natural fibers. The driving belt also contains an electrically conductive element. The supporting element is connected to a non-crosslinked plastic covering to form an asymmetric structure. The textile supporting element can be impregnated on the side facing away from the plastic covering. The electrically conductive element is either an electrically conductive filament in the multifunctional thread or yarn or an electrically conductive layer between the supporting element and the plastic covering. This asymmetric structure results in a favorable kinematic operating behavior and high efficiency, because the neutral bending plane of the belt comes to rest at a point very near the contact surface of an element to be driven. Together with the anti-static properties and the positive connection between the supporting element and the plastic covering, the driving belt prevents the adhesion of fiber fly and makes it possible to cut it off from a supply roll as desired and connect the belt ends without any impact effect during passage over a spindle.

Abstract: A hub/tape clamp arrangement for tape-like or strip-like articles consists of a recess in the peripheral edge of the hub, having one or more middle projections, and a tape clamp having the shape of an inverted W. In practice, wedge-shaped locking means between the projection and/or walls of the recess and the tape clamp may serve to retain the clamp and fix the tape. Steps at the ends of the recess, and extensions or steps in the hub recess which have been matched up in shape, increase the possibilities for monitoring/measuring dimensions. If the tape is fastened asymmetrically on one side, the tape clamp rises out of the recess on one side by a distance precisely the same as the tape thickness, so that the tape emerging from the recess is wound at the same level, i.e. the empty hub has a roughly screw-shaped peripheral contour. The hub can be designed for use with or without one or more flanges and is particularly useful for thin tapes, e.g. magnetic tapes.
