Abstract: Radioactive waste occurs for example in the form of contaminated powdery ionic exchange resin. This ion exchange resin is to be made suitable for final storage by reducing its volume as much as possible. According to the invention, this is performed by a process according to which the ion exchange resin is mechanically dewatered, the dewatered ion exchange resin is mixed with a calcium compound, is then dried with the addition of heat and after which, finally, the dry mixture is thermally treated at a pressure of less than 1000 hPa by heating up to a temperature in the range from 120 to 190°C. The ion exchange resin thereby loses its water absorption and swelling capability.        Ion exchange resins treated in this manner are processed with cement or bitumen to form blocks suitable for final storage.

Abstract: Disclosed is an extension ladder mainly including a pair of telescopic legs consisting of a plurality pairs of straight round tube members, a plurality of rungs in the same numbers as that of the tube member pairs and each having two lateral ends for the two legs to pass therethrough, a plurality sets of locking mechanisms and lock ensuring mechanisms, and a general switch assembly disposed beneath the lowest rung. The tube member each has a sleeve member and a plug assembly disposed around a top end and in a bottom end, respectively. Each plug assembly includes a set of cover members and a set of inserts having an upper and a lower movable hook members connected thereto. The upper hook member in a lower tube member separately links with the lower hook member in a higher tube member, limiting the tube members of the telescopic legs to be sequentially extended stair by stair. The upper hook member each has an air cock provided at a bottom end thereof to close or open an air port formed on a base of the inserts. The air cocks and the air ports, together with two one-way valves separately disposed at a lower portion of the lowest tube member pairs, enable the ladder to be quickly extended from a collapsed state and be collapsed from an extended state at moderate speed. The locking mechanisms and lock ensuring mechanisms are disposed beneath each rung to effectively prevent the ladder from unexpectedly collapsed due to any accidental touch of the locking mechanisms. The general switch assembly serves to actuate and control the sequential and moderate collapse of the rungs.

Abstract: A postal service purchasing system involves the mailer entering information, such as delivery address, weight of mall piece, services required, about each mail piece using for example a personal computer.  Electronic postal counter software installed at the mailer's premises causes the information entered to generate a barcode identifier for each mail piece and this barcode identifier is printed on the mail piece.  An electronic manifest containing the identifier for the mail pieces is transmitted to a computer at the Post Office Premises.  As each mail piece is subsequently sorted the identifier information is captured and reconciled with the information on the electronic manifest.

Abstract: A microwave filter has a plurality of resonant cavities with each cavity containing a dielectric resonator.  There are self-equalizing probes or self-equalizing apertures located between some of the cavities.  A circulator is connected to an output of the filter.  The circulator has an input/output which is connected to an equalizer.  The equalizer contains a dielectric resonator that is slightly different from the dielectric resonators of the filter to permit the equalizer to be tuned at a slightly different frequency from the filter.  The equalizer and self-equalizing probes or apertures are capable of being operated to reduce a dispersive slope of the filter.  The filter can operate in a single mode or a dual mode.  The electrical performance of the filter is superior to prior art filters, particularly in the wideband versions because the dispersive slope is reduced.

Abstract: The present invention provides a signal loss recovery device (400) and method for digitally encoded bitstreams produced by predictive encoders, for realtime and/or interactive communications.  The signal loss recovery device (400) recovers the lost or damaged information by sending a retransmission request for the lost information from transmission receiver (302).  Compared to the previously known retransmission technique, this device does not introduce extra buffer delay. The elimination of this buffer delay is realized by continuously processing the received data while waiting for the arrival of the retransmission.  The information is reinserted into the error corrupted signal to restore the output signal to its original form without signal loss.

Abstract: When manufacturing a foil-wrapped breast prosthesis with a filling consisting of a curable compound, the curing is performed after placing a filled prosthesis bag, formed by contour welding of two joined foil sheets, in a mould cavity (6) without closing  the mould cavity and maintaining vacuum at least in the beginning of the curing, whereby especially an increased degree of freedom is obtained with respect to shaping the rear side of the prosthesis, so that this, among other things, can  be provided with thin edge parts for obtaining good fitting to the body.  To ease the mounting of the bag and the accurate positioning of this in the mould cavity (6), the latter is formed in a first mould part (5) of a shaping tool, which furthermore comprises a tightening frame (10) having a packing (12), which provides an unambiguously oriented tightening  of the bag when this is placed in the mould cavity (6).

Abstract: A low resistance electrical connector comprising a flat bar having multiple lateral fingers projecting from the bar to form flat compression pads for attachment of electrical connectors, and an insulating housing surrounding said bar and including relatively short cylindrical projections enclosing a short extent of each finger and presenting a circular shoulder at the proximal end of each finger or the inner end of each compression pad so that a rocket may telescope over the shoulder and seal the connection to each pad. The number of fingers projecting from each bar may vary and they may project from one or both lateral sides of the bar. The connector is made by laser or waterjet cutting a flat sheet or bar of conductive metal such as copper, aluminum or a laminate to form a blank. The sheet is cut to avoid excessive scrap so that the space between fingers becomes the fingers of another blank. The blank is deburred and placed in a mold to formthe insulating housing and cylindrical projections. Holes are drilled and tapped in the projecting pads either before or after molding.

Abstract: A method for packaging cans or tubes continuously delivered from a production installation to pick-up elements, which are moved in steps, of an intermediate station. A gripper device brings the cans or tubes in groups according to the desired number of pieces in a packaging layer to a delivery station. Each can or tube is deposited into a support element, after which the cans or tubes are pushed together out of the support elements into a loading station. The cans or tubes are placed at equal distances into the pick-up elements, wherein individual support elements are placed apart from each other at a predetermined distance. The cans or tubes are then deposited into the support elements at distances predetermined by the pick-up elements. The support elements are subsequently moved together until they touch each other, whereupon the cans or tubes are then pushed into the loading station. This method allows the use of the same apparatus for different can diameters with minimal changing effort.
