Abstract: A method and means is described for correcting multiple error bursts in data recorded on a storage medium in blocks, comprising a plurality of sub-blocks. After reading the data, decoded block check syndromes are algebraically summed with estimated block check syndromes to provide a set of syndromes for a code for locating sub-blocks having an error burst. This set of syndromes is decoded to identify each sub-block having an error burst. Concurrently block level syndromes are computed to identify the locations and values of errors within the sub-blocks having error bursts. During writing, the data in all sub-blocks of a block is encoded and block level syndromes are generated for these sub-blocks. These block level syndromes are multiplied by a series of preselected weighting factors (α' ... α 1(B-1) ) according to the location index I of the sub-block within the block and as multiplied, each is stored in a different one of B buffers. These are cumulatively summed to produce block check syndromes, which are encoded after the last sub-block of the block is written to provide check bytes for their protection. These check bytes and the weighted cumulative sums are stored on the medium at the end of the block as block check syndromes. , and more specifically relates to such a method and means which includes error correction code (ECC) for which decoded and estimated block check syndromes are generated

Abstract: An apparatus which delivers to an operator offset batches of sheets reproduced from at least one set of documents. The operator selects the number of sheets or sets of sheets in successive batches to be offset from one another. In this way, the number of copy sheets in the batch may range from a partial set of copy sheets to multiple sets of copy sheets. Also, the operator may select no offset within a job providing a straight stack with no distinction between batches or sets.

Abstract: When data read out from a memory cell array (11) is output to an external device through an output buffer (15), a first read control pulse signal (P1) and a second read control pulse signal (P2a) are generated in response to a change in address signal (Add). An operation for reading out data is controlled using the first and second read control pulse signals (P1, P2a). By such control, when an address signal (Add) seems to be changed by noise generated by a change in power source potential or the like due to a change in output, the noise can be removed, and thus the output (15) buffer is not erroneously operated.

Abstract: Effluent gas streams from power plants, or other sources, containing entrained particulate matter are conditioned by injecting a conditioning gas such as sulfur trioxide into the flowing gase stream (20). The conditioning gas contained in the source of gas (32) is deposited upon the surface of the particulate and reduces its electrical resistivity, improving the performance of electrostativ precipitators (38) through which the flowing gas (58) is passed to precipitate the particulate. At the point of injection (34), an electrostatic potential (40,46) is established between the particulate in the flowing gas stream (20) and the conditioning gas molecules, so that the conditioning gas is attracted to the particulate. Interaction of the conditioning gas with the particulate is stronger and more rapid than in the absence of the electrostatic potential (40,46) at the point of injection (34).

Abstract: A radiating cable of the foam dielectric type is provided with improved water-blocking characteristics by provision of a barrier tape between an apertured, corrugated outer conductor and the external jacket surrounding the conductor. The barrier tape is wrapped around the outer conductor is such a away as to completely cover the radiating apertures disposed thereupon. The barrier tape is composed of a hygroscopic material which is highly water absorbent and swells up in contact with any water penetrating the cable so as to form a barrier around the aperture conductor, thereby preventing ingress of water into the apertures of the conductor. The barrier tape is particularly effective in restricting longitudinal migration of water by retaining water that contacts the tape in a high localized fashion. The improved radiating cable construction is particularly adapted to be used in conjunction with a layer of fire-retardant tape disposed over the water-blocking tape to realize a cable which is highly resistant to both water and fire and yet is economical and easy to manufacture and use.

Abstract: An interference sensor passes radiation from a source (10) and a polariser (30) to a loop (40) of optical fiber so that radiation beams circulate in opposite directions around the loop (40) and interfere. The loop (40) contains an optical phase modulation (50) which imposes an optical modulation on the radiation beams circulating on the loop (40). A converter (70) detects the interfering and modulated beams and generates an interference signal which is then processed by an analyser (100). The interference in the loop (40) is dependent on rotation of the loop (40) and therefore analysis of the interference signal permits that rotation to be measured. In the present invention, the interference signal is (i) sampled at a frequency different from that of the optical modulation, or (ii) electronically modulated on the analyser at a frequency different from that of the optical modulation, or (iii) optically modulated in the loop (40) at a second optical modulation frequency. The analysis in the analyser (100) may be in the frequency domain (i.e. consideration being given to the frequency of the interference signal) or in the time domain, (i.e. independent of frequency).

Abstract: Reactive ion plasma etching apparatus and method are based upon the discovery of enhanced uniformity of etching at low workpiece temperatures. With cooling to sufficiently low temperatures, spontaneous etching is inhibited and etching uniformity is controlled not by gas flow and pressure but rather by ion flux. As a result, one can eliminate uniformity enhancing apparatus which heretofore obstructed optical access to the workpiece, provide window means permitting optical access to a major portion of the workpiece and employ sophisticated optical monitoring techniques during the etching process.
