Patent FR-2132572-A1 (FR)
Title: Gas cooled reactor - with core and primary coolant circuit incorporated in concrete pressure vessel
IPC: G21C1/32
Filed: 1971-04-09
Abstract: A gas cooled reactor concept applicable to prismatic cores with rod type fuel or pebble bed type cores with gravity discharge. The basic configuration is for a central reactor core within a column supported concrete pressure vessel. Primary coolant circulators and heat exchangers are arranged in liners in the concrete pressure vessel spaced circumferentially around and beneath the core but integrally connected to the reactor chamber. Gas flow which may be CO2 or He is downward through the core, heat exchangers and circulators with an upward return flow. Secondary coolant circulation through the heat exchangers is counter to the primary to maximise heat transfer. Improved thermal efficiency leads to reduced plant dimensions with consequent advantage to high pressure and high power reactors.

Title: Carbon arc lamp electrode - having protective coating to reduce operating temp. and oxidn. increasing electrode life
IPC: H05B31/14
Filed: 1974-05-20
Abstract: A carbon electrode comprises (a) a C bar electrode having a discharge tip at one end and a holding section at the other, (b) a coating of Al or predominantly Al-alloy on all peripheral surfaces of the bar except the discharge tip and (c) a second coating of Al2O3 and Si oxide on all peripheral surfaces except the discharge tip and holding end. The electrodes are useful for sunshine or ultra-violet carbon arc lamps used for fading and weathering tests on paints or fabrics. Electrodes life is increased by up to 20%. As the C is consumed and Al melts, the molten Al combines with the oxide and forms a vitreous ceramic which descends under gravity so no molten metal coats the lamp envelope and reduces transmittance. The exhaust contains no toxic materials. The ultraviolet output is about the same as that of lamps using conventional C electrodes, but infra-red output is reduced.

Title: Filtering centrifuge with liquid separator in feed line - esp. with internal screw expelling excess liquid through filter
IPC: B04B11/02
Filed: 1974-08-27
Abstract: A filtering centrifuge has a feed pipe leading into the revolving filter drum; this feed pipe comprises a length esp. an axial portion of the pipe inclined to the vertical, in which the interior of the pipe is connected by a filter to the surrounding space. Pref. the length of feed pipe comprising the filter has an internal screw driven by a motor. This centrifuge is use for any kind of filtering where there is a tendency to an excess of liquid over that required for satisfactory centrifuging. By reducing the amount of liquid entering the drum, the power consumed in accelerating the suspension or mixture is reduced in relation to the solids obtained. In addition, other diadvantages such as the difficulty of forming a satisfactory filter cake on the wall of the drum when excess liquid is present, are avoided.

Title: Inflatable structures (kayaks) of reduced pneumatic capacity - having foam filled segments to reduce inflation cycles
IPC: B63B7/08
Filed: 1974-12-18
Abstract: Inflatable structures involving rigid elements and short inflatable butr inextensible sleeves connected in series so that inflation of the selected creates a rigid composite structure which can support a larger flexible structure to which the composite element is bonded. Suitable for making one piece collapsible boats, esp. kayaks, or other structures requiring to be folded for portage or storage. The reduced pneumatic capacity obtd. by only involving flexible chambers at hinge points instead of throughout the supporting structure reduces the gas quantity and inflation/deflation periods required, allowing quite large structures to be erected from a small (self-contd.) pressurised reservoir. The composite structure retains greater buoyancy if punctured. The rigid sections of the supporting structure may be continuations of the flexible, impermeable sleeves used for the inflatable portions, but prefilled with rigid closed cell foam such as polyurethane.

Title: Clip for attaching flexible tubes to pipes - is spring material band with integrally formed ratchet and pawl on ends
IPC: F16L33/035
Filed: 1975-01-09
Abstract: A clip for attaching flexible tubes or covers such as radiator hoses in cars, to rigid pipe ends consists of a spring material band (10) circular in form when free and having a narrower tongue (11) with outwardly turned tip (13) at one end and a hole (14) at the other end. The hole is rectangular and of a width to guide the narrow tongue when inserted, insertion being simplified by the outwardly turned tip. A series of teeth (20) are pressed in the outside face of the tongue and these engage with a spring pawl (18) which is pressed out during the formation of the rectangular hole. When the tongue is inserted in the hole a ratchet and pawl is therefore formed. Pressure to tighten the clip is applied by pliers to a raised portion (16) near the tongue and to the turned back other end (15) of the clip.

The micro-instructions are stored sequentially in a passive memory, so as to form a micro-programme. The line base for execution of the micro-programme is defined using the particular field of each micro-instructions, for addressing one of several lists, stored in a second passive memory, and corresponding respectively to the types of micro-programme. Each list comprises a given number of words addressed sequentially, which are read in synchronism with a clock, and which define the elementary stepping sequence for executing the micro-instruction.

Title: Plasma powder spray gun - has a concave reflector for collection of infra-red radiation from the flame and reflection onto the workpiece
IPC: B05B7/22
Filed: 1975-04-14
Abstract: A plasma pistol with a nozzle for the generation of aflame for applying powdered material e.g. plastics and certain metals, onto a substrate, has a reflector (i) mounted in the vicinity of the nozzle to reflect infra-red radiation, generated in the plasma flame, towards the substrate and (ii) having a concave form, particularly ellipsoidal, parabolic or cylindrical, for the reception and focussing of the radiation to a limited region of the substrate. The recovery of the infra-red energy enables a higher temp. to be reached on the workpiece so that a more uniform deposit is produced by the flame spraying. Moreover, the electrical efficiency is higher.
