Title: Analysis of liqs. contg. dissolved gases - esp. in circuits under pressure, e.g. pressured water fission reactors
IPC: G21C17/022
Filed: 1973-07-02
Abstract: A process for sampling and separating liq. and gaseous phases, from a circuit contg. liq. under pressure at ambient temp., consists of isolating a vol. of the liq. in a prim. container which is connected to a second buffer container and a third removable container. The second and third containers can be under vacuum, reducing the pressure in the first container when connecting valves are opened, and causing transfer of a large part of the gas dissolved in the liq. in the first container, the remainder being swept out by inert gas. The sample of gas thus obtd. in the third container is analysed and from the vol. and press. the compsn. and quantity of the gas dissolved in the liq. under press. in the circuit are determined. The system is integral with the circuit and provides two phases immediately usable for analysis, giving a means of detecting rupture in pressured water fission reactors. It may be used in all liq. circuits contg. radioactive gases, miscellaneous containers, effluent circuits, etc.

Title: Encasement of metal pipes in prestressed concrete - has radial clearance space between metal and concrete filled with mortar under pressure
IPC: F16L58/06
Filed: 1974-07-26
Abstract: Metal pipes are encased in prestressed concrete covers in such a way that cracking of the concrete shell is avoided and the metal is completely protected from exterior mechanical flange and chemical attack. The technique consists of preforming the concrete shell (1) so that its internal diameter is greater than the eternal diameter of the metal pipe (4), leaving a space from 2-20mm. between the two. When the shell has set completely and is dimensionally stable, the metal pipe is centred within it and the gap filled under pressure with mortar or an epoxy cement. Either a simple filling or a bonded joint is thus obtained. In addition if the filling is performed after sections of pipe have been laid and joined, a good sealed joint is obtained.

Title: Collector for solar radiation energy - has blackened elliptical or oval water tubes to achieve highest possible temperature
IPC: F24S23/70
Filed: 1975-12-05
Abstract: The collector has a rectangular casing with a flow header on one side and a return header on the other. Straight water tubes (3) run parallel to each other from one header to the other. Above the water tubes there are insulating bars (4) and two glass sheets (5a, 5b) with a thermally insulating gap between them. Below the water tubes is a reflecting surface (11) which rests on thermal insulation (12) in the bottom of the casing. The water tubes (3) have blackened external surfaces and have an elliptical or oval cross section. This gives a small volume for a large surface area so that the radiation is absorbed by a small quantity of water which therefore reaches a high temperature.

Title: Probe for measuring melt thermal conductivity and diffusivity - using a sheathed linear heating probe with a central sensor
Inventor: DIETZ WOLFGANG
IPC: G01N25/18
Filed: 1975-12-17
Abstract: An instrument for measuring the thermal conductivity and thermal diffusivity of a material, esp. polymers under press., is based on use of a linear temp. sensitive probe traversing a sample chamber coaxially. The ratio of the min. internal cross-section dimension of the chamber; max. external cross-section of the probe is 25:1-100:1. The press. on the material in the chamber can be increased by an ancillary thrust device. Used for simultaneous determination of thermal conductivity and diffusivity under dynamic thermal flux by dissipating a heating current via the probe traversing the chamber. Results are obtd. from classic time/temp. plots as detected by the central sensor in the probe. It is suitable for measurements at typical polymer processing press. and temps. and avoids end effect errors of the order of 10% associated with use of cantilever probes. It is also more robust than use of thin plain resistance wire heater/probes.
