Title: Thermally insulating bulky product and method for its manufacture
IPC: D04H3/03
Filed: 1980-04-28
Granted: 1984-09-26
Abstract: A thermally insulating nonwoven bulky product is made up of substantially continuous single filaments of between 0.01 to 2 deniers stabilized in the product by a surface binder on the filaments. The bulky product may be made from multi-filament polyester (2) direct from the spinneret by passing it in a high speed air current through a nozzle (3) and against a surface (4) where it is broken into single filaments (8) which pass through a mist of binder emulsion ejected from a spraying nozzle (5) and so are deposited on a support conveyor (6). The speed of the conveyor (6) is adjusted so that the filaments settle in folds giving a pile of substantial thickness which is then dried and heat set under heated elements (7). The product, which may well have a bulkiness between 50 and 550 ml/g, can be used for filling articles such as duvets, sleeping bags, anoraks, and the like, and has a thermal insulation comparable to that of down.

Abstract: A mill liner for a dry autogenous mill includes low profile end liner elements (12, 15) at the ends of the mill incorporating radial ribs (19, 20, 21) with proper height to provide significantly improved mill performance without sacrificing the grinding efficiency. Shell liner elements (40 or 44) are also provided with lifter bars (41 or 43) as an integral part thereof to simplify maintenance work as well as reduce scrap losses. For the larger size mills, the shell liners are preferably made of a three piece design, a middle section (44) and two identical end sections (45), thus permitting the middle section which bears most of the wear to be replaced without having to replace the two end sections.

Granted: 1986-01-15
Abstract: A satellite communications system, which is inherently power limited, employing spread spectrum techniques in order to trade-off bandwidth for small ground station antennas. In a one-way system embodiment a central station (14) transmits data to a satellite (3) for relay to a large number of small antenna receiving stations (4), the transmissions being spread spectrum encoded with spreading code lengths selected to provide adequate data recovery at the least sensitive station to which the transmissions are directed. Spreading codes may also function to address particular stations. In a two-way system embodiment, the central station (14) additionally functions as a terrestrial relay station. A plurality of small antenna transmitting stations, at least one of which may be at the same site as a receiving station, transmit code division multiplexed data via the satellite to the central relay station using sufficiently long and distinct spreading codes as to permit adequate data error rates and to distinguish the transmissions of the various stations. The central relay station reformats the received data for retransmission to the satellite for relay to the receiving stations.

Abstract: An automatic fingerprint enrollment and identification technique is provided for automatically processing an input image represented by pixels having either a one or a zero value. The automatic processing involves a series of steps in which the initial processing is a rough screening technique for eliminating a reasonable portion of the noise while passing through almost all of the minutia. As the steps proceed, the processing becomes more complex to provide a tighter screening out of noise while passing through as much of the minutia as possibe. The later steps by operating on relatively fewer minutia or anomaly points that the earlier steps can be economical though more complex so as to be more discriminate than the earlier steps. The processing provides an optimum trade off between enrolling as large a proportion of the population as possible while minimizing the number of false identification errors.

Abstract: A method and apparatus for bending tubular workpieces whereby a tube length is placed in front of a template and selectively driven deforming shoes urge the tube into engagement with the same. Where the desired tubular radii of curvature are relatively large the deforming shoes are driven from a stationary mount. Where shorter tubular radii are desired, generally near the tube ends, the deforming shoes are arranged such that they are incrementally translated along a path commensurable with the contour of the template. At each successive increment the deforming shoes perform a bending operation upon the tube such that it may be successively formed into its desired shape.
