Patent FR-2257084-A1 (FR)
Title: Analysis of elements close to the surface of a solid - by directing pure molecular beam over the surface, and observing the light spectrum
IPC: G01N23/22
Filed: 1974-01-07
Abstract: A pure molecular beam, pref. of helium atoms, is directed onto the surface of a solid and the light spectrum emitted by the varying elements is analysed on a monochrometer by comparison with spectra of known elements. The energy of the molecular beam varies from 0.1 to 1 electron-volt for elements on the surface, 1 to 25 electron-volts for elements near to the surface and over 25 electron-volts for heavier solids. It is possible to direct several beams onto the surface so that the elements at various points can be simultaneously and continuously analysed. By filtering the light emitted so that only that of a certain element is allowed through it is possible to obt. the concn. of that element over a swept area, and by bombarding one spot of the surface with the molecular beam a graph of concn. of element with depth from surface can be made. A thin transparent layer of a body can be observed from the side opposite that of impact of the beam. Used for surface analysis of metals and alloys and partic. for biological analysis e.g. cells and tissues. Pure molecular beams with neutral atoms is not repelled so closer beam can be maintained over longer distance. Neutral atoms of pure molecular beam are less harmful hence sample can be under higher pressures approx 10-3 torr, giving also longer analysing time as degassing occurs more slowly. The intensity of the light emission does not depend on the form of the surface.

This is effected by a combination of slots, hinges and also link pieces. These give adjustments in the line of the cable and transversely to it. The attachments are carried by supports (12) which are pivotal and slidable in overlarge openings (13) in the bogie (2).

Title: Telephone receiver with ringing apparatus - has bell permanently across line with shunt to prevent outgoing calls ringing local bell
IPC: H04M19/04
Filed: 1974-04-26
Abstract: The signal bell (2) of this telephone receiver is permanently connected accross the telephone line (L1, L2) in series with a capacitor and a non-inductive resistor. It rings upon receipt of normal call signals from the exchange. When the handset is lifted, the cradle switch places a voltage detector across the bell. This comprises two Zener diodes (7) that form a short-circuit at signalling voltages. The cradle switch also puts the receiver across the line so that speech signals may be received. When calls are originated, the Zener diodes shunt the local bell. Electronic signalling may therefore be used with non-operation of the local bell in full compliance with P.T.T. regulations.
