Title: Optical fibres with low attenuation - drawn from fused silica blank contg. multilayer core of doped silica and flux (NL191076)
IPC: C03B37/018
Filed: 1976-04-16
Abstract: In the mfr. of an optical fibre using a round quartz tube, a vapour mixt. is formed from O2, SiCl4, a dopant and a flux and fed through the tube which is zone heated to form a deposit adjacent to the moving hot zone; the deposit is then melted to form a layer in which the dopant produces a higher refractive index (R2) than that of the tube, the flux lowering the m.pt. of the layer; the process is repeated to form several layers and the tube is then heated above its softening point so it collapses, forming a bar which is drawn into an optical fibre. The amt. of dopant is pref. altered to form a sequence of layers with progressively increasing RI. Used of fibres with low attenuation due to a substantial redn. in scattering centres and Rayleigh scattering.
Patent FR-2316464-A1 (FR)
IPC: B29C65/00
Filed: 1976-06-30
Abstract: Described herein are coupling means for joining substrates, for example, tubular articles, which include an inner member, having disposed thereon a fusible agent for binding the substrates together, and an outer member. The substrates to be joined are inserted between the fusible agent and outer member and the resulting assembly is heated. The application of heat is maintained until it permeates the assembly and raises the temperature of the fusible agent enough that it melts and flows through and/or about the substrates to be joined. The inner and outer members act to confine the melted fusible agent by defining boundaries between which it can flow. Longitudinal flow of the agent can be controlled by limiting the area heated, by the configuration of the coupling members or substrates, or by providing the coupling with additional members that "dam" longitudinal flow. When the heating is discontinued, the fusible agent hardens to bind the substrates together. Either the inner member, outer member, or both may be a heat recoverable or spring member to provide compressive forces in the area of the joint being formed to facilitate the flow of the fusible material.

Title: Traffic light coordination control system - uses magnetic loop point referencing system to determine mode of light operation
Inventor: RACIAZEK ANDRE
IPC: G08G1/082
Filed: 1977-02-03
Abstract: The traffic light coordination control system is of the type which uses vehicle detectors. It also uses elements which switch the traffic lights at crossroads according to a periodic cycle corresponding to an determined plan. A logic element processes the plan as a function of the data collected by the detectors. At least some of the detectors, alone or in association furnish magnitudes representing vehicle flow as well as occupation rate to the right of the detector. The system only detects the number of vehicles passing in unit time. Some of the detectors are of a type sensitive to the presence of a vehicle, whether immobile or moving very slowly. A simple buried magnetic loop is used for counting. The flow and occupation rates are measured in various places by separate detectors or by a single element capable of supplying itself both types of information. The logic element calculates at regular intervals the average values of each secondary magnitude. These values each define a coordinate of a point in a space having as many dimensions as there are detection points. The distance of the point from fixed reference points is calculated to determine plane to be used.

Title: Low light level measurement photomultiplier system - has pulse shaper circuit and integrator for high stability operation
Inventor: THOMAS ALAN JOHN
IPC: G01J1/44
Filed: 1977-07-20
Abstract: The photomultiplier-based system for measuring low light levels is esp. suitable for use in fluorescence and chromatographic measurements. The output of the measuring cell is transmitted through a light-guide and filter to a secondary-electron multiplier tube. The output pulses corresponding to the individual photons, are amplified and pass through a threshold circuit for noise and interference suppression. They are then converted into pulses of constant amplitude and width by a multivibrator-limiter shaper. The pulses are then integrated at a predetermined rate of up to 107 pulses/sec. The system thus operates independently of the stability of the photo-multiplier tube.
