Abstract: The stepwise high precision winding method includes winding the yarn on the bobbin with a reciprocating yarn changing guide in a series of steps so that an outer circumferential speed of the yarn-bobbin package is constant; reducing the yarn guide reciprocation frequency in each step from a starting frequency value to a final frequency value while keeping a winding number constant during each step so that the final frequency value is proportional to a bobbin rotation frequency in each step, and then increasing the yarn guide reciprocation frequency discontinuously to another starting frequency value and beginning a following step with the yarn guide reciprocation frequency equal to the other starting frequency value; setting the starting frequency value in each step to not more than a fixed maximum frequency; setting the final frequency value in each step to not less than a certain fixed minimum frequency; and setting the winding number in the Sth step equal to either iS-iSx/(MS+x) or iS+iSx/(MS-x), wherein x=a/2H; iS is a mirror value for the Sth step, MS is the order of the mirror value for the Sth step, a=the lay spacing between windings of a Kth lay and a (K+MS)th lay and H is a total height of the yarn-bobbin package.

Abstract: The present invention is directed to an automated peptide synthesizer equipped with recovery lines including an acyl component recovery line for recovering unreacted acyl components to allow the reuse of the acyl components, and a solvent recovery line for recovering and distilling a reaction solvent and passing it through a purification column to allow the reuse of the reaction solvent. Both recovery lines are installed on the flow pathway from one or more reaction chambers or columns to a waste liquid reservoir of the automated peptide synthesizer. By recovering expensive acyl components and solvents, running cost in peptide synthesis can be reduced to mitigate economic burden, and the amount of waste leading to environmental destruction can be reduced.

Abstract: A matrix display apparatus includes an addressing circuit for addressing pixels of the display by means of row-address conductors. The addressing circuit includes a shift register having successive stages coupled to the pixels through respective buffer devices which are electrically connected in the row-address conductors. In order to circumvent defects which would prevent a timing pulse from propagating through individual stages of the shift register, a number of spare shift-register stages are distributed along the length of the shift register. The spare stages can be connected in place of defective stages of the shift register via a pair of reparative conductors which insulatively cross the row-address conductors. Spare buffer devices are similarly provided.

Abstract: A device (20) and a method for insertion of the device (20) into a puncture (26) in the tracheoesophageal wall (28). The device (20) includes a cylindrical body (22) and a flexible first flange (32) provided on an outside surface of the body (22). The flange (32) has a use orientation in which it projects generally outwardly from the outside surface of the body (22), and an insertion orientation in which it is resiliently folded toward the axis of the body (22). A retainer (44), (144) retains the flange (32) in its resiliently folded orientation. The retainer (44), (144) is removable to permit deployment of the flange (32) to its use orientation. A tool (80) for use in placing the device (20) comprises a cylindrical passageway having a cross section slightly larger than the cross section of the cylindrical body (22), but smaller than the flange (32). The passageway has an open end (84) for receiving the device (20). The edge of the open end (84) causes the flange (32) to be resiliently folded toward an axis of the body (22) as the device (20) is inserted into the passageway. A retainer (44), (144) for retaining the flange (32) in its resiliently folded orientation is received at the open end (84). The device (20) is ejected from the passageway through the open end (84) with the flange (32) retained in its resiliently folded orientation by the retainer (44), (144).

Abstract: A portable radio telephone device which is in the form of a wristwatch which is fastened to the user's wrist via a strap. The telephone device is comprised of two main components, a case and a strap. The case has a display and a transceiver. The strap or band has at least a top and a bottom layer which are attached to the case. The top layer of the band is releasable in the proximity where the case and strap meet. However, the top layer remains connected to the bottom layer of the strap by a pivotable hinge. The pivotable hinge is typically located opposite the case and perinits the top layer to be rotated. The length of the top layer can be increased either by repositioning the case or having additional layers located beneath the top layer. The speaker is located on the end of the released top layer. The microphone is located on the band. When the top layer is released and rotated, the speaker is located in the palm of the user's hand and the microphone is positioned along the inside of the user's forearm. This design provides for a private telephone conversation without the removal of the telephone device from the user's wrist.

Abstract: L'invention se rapporte à un procédé d'analyse d'un système de communication pour localiser la source d'un dérangement. Le système de communication comprend un support de transmission de signaux (9) connecté à une série d'accès de stations terminales (2-6), qui permettent aux stations terminales respectives (24) d'émettre des signaux vers le support et de recevoir des signaux à partir de celui-ci, et une unité de contrôle de transmission (9) pour commander la liaison des stations terminales (24) avec le support par l'intermédiaire des accès (2-6). Le procédé consiste à déconnecter les stations terminales (24) en série à partir du support (9) suite à la détection d'une panne et à rechercher ensuite si la panne est toujours présente. Un analyseur (10) de panne conçu pour réagir à la détection d'une panne amène l'unité de contrôle de transmission (8) à déconnecter d'abord une station terminale (24) qui a été précédemment caractérisée comme la source la plus vraisemblable de la panne. L'unité de contrôle de transmission (8) peut déconnecter des groupes de stations terminales (24) et reconnecter des sous-groupes si la panne ne se trouve pas dans le groupe qui n'avait pas été déconnecté tant que la station terminale défaillante n'a pas été identifiée.

Title: Process for converting hexafluoroarsenic acid or any salt thereof to a water insoluble arsenate salt which can then be rendered nonhazardous.
Inventor: REDMON CHARLES LEWIS
IPC: C01B7/19
Filed: 1993-09-14
Abstract: This invention provides a process for the conversion of hazardous hexafluoroarsenic acid or a salt thereof to an arsenate salt that can be rendered non-hazardous. In particular, hexafluoroarsenic acid or a salt thereof is converted to the solid insoluble calcium or magnesium arsenates or mixtures thereof which are water insoluble. Known stabilization technology renders the material non-hazardous. The present process involves converting hexafluoroarsenic acid or a salt thereof contained in an aqueous mixture to an insoluble arsenate salt. The process comprises the steps of: (a) adding a first compound selected from group (I) or group (II) to the aqueous mixture in an amount sufficient to substantially neutralize the aqueous mixture to a pH greater than or equal to about 10; and, if the first compound is selected from group (II), in an amount sufficient to substantially convert fluoride ions to solid water insoluble calcium or magnesium fluorides or mixtures thereof and to substantially hydrolyze the hexafluoroarsenic acid or salts thereof to solid water insoluble calcium or magnesium arsenates or mixtures thereof in subsequent step (b), and if the first compound is selected from group (I), adding a second compound from group (II) in an amount sufficient for said conversion of fluoride ions and said hydrolysis; and (b) reacting the mixture resulting from step (a) at a temperature and for a time sufficient for said conversion of fluoride ions and said hydrolysis. Prior to said step (a), the process further has the benefit of recovering the hydrogen fluoride from the starting aqueous mixture as a product if desired or for decreasing the volume of waste to be rendered non-hazardous.
