Abstract: A method of rapidly reducing chromium oxide-containing slag and the like in large quantities, in a simplified manner and without requiring high temperatures.  Chromium oxides are reduced with at least one of elementary sulfur and compounds of sulfur having a valence less than 6.   For an aqueous solution  of  the  sulfur  component,  desirably,  its  sulfur content is more than 0.03 % by weight.  As the sulfur source, preferred is blast furnace slag (e.g., non-aged, gradually-cooled blast  furnace  slag)  that  is  discharged  in  large quantities in the iron industry.  Cr6+ in chromium oxides is reduced in one of the following ways:   (a) Chromium oxide-containing substances are sprayed with or immersed in blast furnace slag-released water that has been used in cooling blast furnace slag.  (b) Chromium oxide-containing substances are mixed with blast furnace slag, and then kept in an air atmosphere.   Optionally, the mixture is sprayed with blast furnace slag-released water. (c) Chromium oxide-containing substances  are  mixed  with  blast  furnace  slag,  and  then steamed.   (d)  Prior to the reduction treatment,  chromium oxide-containing substances are preferably steamed 100 parts by weight of reduced chromium oxide-containing compounds are mixed with from 0.1 to 90 parts by weight of sulfur-containing slag, and used in various civil engineering works.

Abstract: Business forms are stacked using a cart having first and second portions pivotally movable with respect to each other from a substantially L-shaped configuration to a substantially in-line configuration with each portion having a conveyor associated with it, and a docking station. The cart with the first and second portions in the substantially L-shaped configuration is moved into operative association with the docking station.      The cart is lifted and rotated in the docking station so that the second portion is substantially horizontal, and the first portion of the cart is pivoted with respect to the second portion so that the first portion is in the substantially in-line configuration with respect to the first portion. The conveyors are operated so that business forms are moved onto the first portion, and then onto the second portion, with the first conveyor operating at a speed of at least fifty percent greater than the first conveyor (e. g. about ten times as fast). An indicator automatically indicates when the frame is substantially full of forms and then the forms are moved off the first portion and operation of the conveyors stopped, and then the first portion is pivoted back to the substantially L-shaped configuration, the cart is lowered and rotated so that the second portion is substantially vertical, and the cart is manually rolled out of contact with the docking station.

IPC: A61F13/15
Filed: 1996-11-26
Abstract: The invention relates to a method of producing reclosable absorbent garments, in particular absorbent pants, and to the absorbent garments obtainable by said method. Starting from a continuous web (1) of absorbent articles attached side-by-side and with a line of weakening (6) arranged between adjacent articles, a first strip (8) comprising releasably attachable material is applied across the line (6) at one edge (25) of the web. A second strip of flexible material is also applied across the line (6) at the other edge (26) of the web. The web is then folded longitudinally to form a series of closed, joined adjacent articles. The adjacent articles are then partially separated at said line (6) but without rupturing said strips (8, 13), so as to provide a free zone (15) between said strips (8, 13) and the adjacent separated edges of each article. The strips (8, 13) are then joined together across the free zone (15) to form a plurality of joined garments. The strips (8, 13) may then be severed so as to form individual garments (27) of the reclosable type, or may remain unsevered and be foreseen with a line of weakening for later separation. Due to the particular method and product features of the invention, an in-line process for making closed, reclosable absorbent garments is achieved.

Abstract: A process for delaminating an organic resin insulation layer and a board therefor without adversely affecting the organic resin multi-layer wiring layer. A polyimide insulation layer is formed on a quartz glass board. Another polyimide insulationlayer and a wiring layer, which together with the polyimide insulation layer form a first block, are laminated on the polyimide insulation layer. The back of the quartz glass board is irradiated with an excimer laser to delaminate the first block and the quartz glass board. Ultraviolet rays from the excimer laser react with the polyimide insulation layer in a photochemical reaction which removes the polyimide insulation layer located at the interface with the quartz glass board and delaminates the quartz glass board from the first block.

Inventor: LUSSIER LUC
IPC: H04L27/36
Filed: 1998-08-17
Abstract: A One Bit Digital Quadrature Vector Modulator (DQVM) and a method of generating single sideband output signals are useful for a wide range of radio frequency, signal processing and wireless applications. The DQVM simplifies the necessary digital multiplication by using noise shaped one bit versions of both the baseband I B and Q B signals to be modulated and the I LO and Q LO modulating signals. The one bit DQVM enables a much faster digital implementation of the digital quadrature vector modulation function than can be achieved with conventional multi-bit digital techniques. In addition the single sideband upconversion of the DQVM achieves high suppression of the unwanted sideband by applying an offset to one of the low speed input samples. Digital vector modulators are an improvement over conventional analog vector modulators as they are not subject to the amplitude and phase matching problems inherent in analog vector modulators.
