Title: N,n'-diacetic acid-n'-cyanomethyl salts thereof and their preparation
Inventor: PARKER BRIAN A
IPC: C07C255/30
Filed: 1992-12-11
Abstract: ABSTRACT A novel intermediate useful in the synthesis of ethylenediaminetriacetic acid (E-D3A) or its salts.  A salt of N,N'-ethylenediaminediacetic acid (ED2AH2) is condensed with formaldehyde to form a stable 5-membered ring intermediate. The addition of cyanide across this cyclic material forms ethylenediamine N,N'-diacetic acid-N'-cyanomethyl or salts thereof (mononitrile-diacid), which is a useful intermediate in the production of ED3A. The nitrile in aqueous solutions may be spontaneously cyclized to form 2-oxo-1,4-piperazinediacetic acid (3KP) or salts thereof. In the presence of excess base, salts of ED3A are formed in excellent yield and purity.

Abstract: Method and apparatus for sensing the color of articles wherein a first pair of wavelengths is selected on a plurality of light reflection curves in terms of reflected light wavelength spectrum, these curves being associated with a plurality of articles constituting a sample representative of the color range to be sensed. The first pair of wavelengths delimits a first range of wavelengths corresponding to light reflection values in these curves, the light reflection values in each of the curves being in a substantially linear relationship over said first range of wavelengths. Each article to be inspected is illuminated with light comprising the first pair of wavelengths, and the light reflected therefrom is measured to detect light reflection values corresponding to the first pair of wavelengths.  A primary signal is produced which represents either a difference between or a ratio of said detected light reflection values, this signal being indicative of the color of the inspected article.

Abstract: The subject invention concerns a method of using in vivo a gene encoding an extracellular interleukin-1 binding domain of an interleukin-1 receptor that is capable of binding to and neutralizing interleukin-1 which includes employing recombinant techniques to produce a cell line under the control of a suitable eukaryotic promoter having the gene coding for the extracellular interleukin-1 binding domain of the interleukin-1 receptor; and initiating transfection of DNA of the gene by introducing viral particles obtained from the cell line directly into synovial cells lining a joint space of a mammalian host. Alternatively, synovial cells from the patient's joint may be transduced with the retroviral vector carrying the therapeutic gene and a selectable marker for selection of only transduced cells, and the now therapeutic autologous cells may be introduced back into the joint by transplantation.  Additionally, a method of preparing a gene encoding an extracellular interleukin-1 receptor binding domain of an interleukin-1 that is capable of binding to and neutralizing interleukin-1 is disclosed. A compound for parenteral administration to a patient in prophylactically or therapeutically effective amounts containing the gene of the invention and a suitable pharmaceutical carrier is also provided.

Title: Removal of metal of graphite
Inventor: HOLDERNESS STEWART G
IPC: C25C5/00
Filed: 1993-08-13
Abstract: Abstract A method of treating scrap graphite having a metal contaminant adhered thereto so as to separate the metal from the graphite comprises placing the scrap graphite in an aqueous oxidising electrolyte and passing through the electrolyte an electric current.  The electric current may be a directional electric current.  The metal may be uranium and the scrap graphite may be that used in the casting of uranium fuel rods.     The graphite body disintegrates in the electrolyte and the metal dissolves at an accelerated rate under the influence of the electric current.  The metal can also break off from the graphite and may dissolve over a longer time period in the electrolyte.  The graphite so treated may therefore be separated from the electrolyte eg by filtering and washing.  Where the graphite has been contaminated with uranium the separation by this process is sufficiently successful to allow the graphite to be disposed of in a conventional manner rather than special means required for hazardous, radioactive materials.

Abstract: Lors de la sélection d'un canal de commande d'une station mobile, dans une zone radio à laquelle certains canaux de commande sont assignés à titre de voie de communication, les niveaux de réception des canaux de commande sont mesurés de façon séquentielle et des canaux de commandes éventuels sont sélectionnés. Une vérification est faite pour voir si un signal de commande peut être reçu correctement dans chacun des canaux de commande éventuels sélectionnés. Advenant que non, le nombre d'échecs de réception du signal pour ce canal est augmenté de 1 dans une mémoire utilisée par la station mobile. Un canal dont le nombre d'échecs de réception du signal a atteint une valeur M prédéterminée (un entier relatif supérieur ou égal à 1) est exclu du groupe de canaux de commande éventuels et les autres canaux de commande éventuels sélectionnés subissent une vérification semblable pour déterminer si la réception du signal de commande est possible ou non dans chacun d'eux. Si le signal de commande peut être reçu correctement par un canal de commande donné, on procède à une vérification pour voir si la station mobile s'est déplacée vers une zone radio différente. Advenant que non, la station mobile se met en état d'attente d'un appel d'arrivée de ce canal de commande. Si la zone radio de la station mobile a changé, le nombre d'échecs de réception du signal de tous les canaux de commande est réinitialisé dans la mémoire, de sorte que tous les canaux de commande deviennent candidats pour être ensuite sélectionnés à titre de canal de commande de la zone radio dans laquelle la station mobile se situe à ce moment.

Title: Process for finding the transmission properties of an electric line
Inventor: ARWEILER HANS W
IPC: H04B3/46
Filed: 1992-03-19
Abstract: Abstract The invention relates to a method for determining the transmission characteristics (H(jf)) of an electric line (2) in an ISDN system, in which a test signal (m(t)) is applied to the line (2) at one end, and at the other end of the line (2) the received signal (g(t)) produced owing to the test signal (m(t)) is evaluated.        In order to be able to carry out such a method using a test signal having a crest factor of one with relatively little cost, use is made as test signal of a binary,  bipolar random number sequence signal  (m(t)) having the crest factor of one, and during a time inter-val corresponding to the period of the test signal (m(t)) the received signal (g(t)) is scanned and subjected to a Fourier  transformation  to  obtain  a  spectral  signal (G(jf)); the latter is complexly multiplied by a refer-ence spectrum Mi(jf) to obtain an output signal (H(jf) which represents a measure of the transmission character-istics of the line (31).
