IPC: H01J49/04
Filed: 1983-04-15
Abstract: A mass spectrometry method for determining the absolute value of a given isotopic ratio of an unknown sample and/or the difference of isotope content between an unknown sample and a reference, comprises a) obtaining with or without chemical reaction a substrate capable of providing a fragmentation characteristic of the presence or absence of a specified isotope and usable to retrace the parent ions by the metastable ions technique consisting of accelerating voltage scan, b) introducing said substrate into the source of a mass spectrometer followed by the ionization of said substrate, c) retracing with metastable ions technique the parent ions of a daughter ion resulting from the loss of a neutral fragment characteristic of the presence or absence of the specified isotope in the substrate, d) comparing the relative intensities as expressed by peak areas or heights, of the metastable transitions between, first, said daughter ion and the substrate parent ion, and second, said daughter ion and a transition characteristic of another isotope of well known abundance and usable as internal reference. For example, a suitable substrate for deuterium determination in water samples is 1-propanol, and for oxygen-18 determination in water samples is ethyl propanoate (propanoic acid, ethyl ester).

Title: Local Area Networks Comprised of Interconnected Sub Networks
Inventor: SWINDLE ROBERT IAN
IPC: H04L12/46
Filed: 1983-04-21
Abstract: A telecommunications system of the LAN type uses closed loops (e.g. Subset 1) each of which has a number of nodes for subscribers and facilities circuits, communication being by digital messages. Each such loop can be a system such as that of our Application No. 8235157 (R. F. Rous 2). The loops are interconnected by interconnection units (I1-2, I1-3, I2-3) each of which provides both way communication between its two loops. Each interconnection unit includes two stores, one per direction of transmission, and a controller which monitors each message which its unit receives. If the message is for a difficult loop it goes into one of the stores from which it is released to the other loop when traffic permits. Thus the loops are treated traffic-wise as if they are one big loop instead of several interconnected loops. Note that a message can pass via two or more loops to each its destination. <IMAGE>

The band (c), which may be of galvanised steel, is on the inside of the cylindrical section, and so is protected from damage by rubbing against stones and other parts of the earth in which the tunnel is being formed. The internal surface of the band may be protected against corrosion by applying a layer of concrete to the internal surfaces. <IMAGE>
