Title: Fibre optic egg candling appts. - illuminates array of eggs simultaneously using series of shielded light conductors
Inventor: THOINET MICHEL
IPC: G01N33/08
Filed: 1981-12-17
Abstract: Egg candling apparatus employs a single, powerful, light source connected by a unit of optical fibres to an array of eggs located in a suitable tray. A sealing glove around the end of each fibre conduit ensures that all the light passes into the egg and that none escapes which would make visual inspection of the eggs more difficult for the operator. Used for the inspection of fertilised eggs to determine the state of embryo development, for use in vaccine culture methods using live embryos, e.g. of flu vaccine.

Title: Thermostatic boiler circulation control valve - has sensor in thermosiphon tube in reservoir controlling valve between tank and feed pipes
IPC: F24D19/10
Filed: 1982-04-16
Abstract: The thermostatic valve for a boiler is arranged between the hot water tank (1) and the flow and return pipes (3,4) respectively. The valve has two seats (10,11). The upper seat (10) opens the passage between the hot water flow (DC) and the outlet (DE) whilst the lower seat (11) opens between the return flow (RE) and the entry (ER) into the tank. The valve is controlled by a sensor (14) under the influence of the temperature in the recirculation tube (5). As the temperature falls, the valve closes the lower seat (11) and water circulates over the element by thermosyphonic action. The valve lifts as the temperature rises and allows flows between the boiler and the heating circuit, and back through the recirculation tube.

Title: Integrating viscosimeter of randomly varying temp. function - measures bubble displacement in calibrated tube filled with two immiscible fluids
IPC: G01K17/02
Filed: 1982-05-06
Abstract: The appts., when submitted to a temperature varying randomly as a function of a time, integrates as a function of time over an arbitrarily chosen interval, a determined function of this temp. The appts. has a sealed calibrated tube of small diameter with a filament fixed at either end to the internal wall of the tube. The tube is filled partly by a liquid (A) capable of adhering to the internal wall of the tube and to the filament, and partly by another fluid (B) non-missible with (A), non-wetting and of different density. One of the two fluids (A) occupies the upper and lower parts of the tube, while the other (B) occupies an interval between these upper and lower parts. The characteristics of the fluids are chosen such that the vertical speed of the bubble in the interval under the effect of gravity varies as a function of temperature according to the determined function. The displacement of the bubble which represents the integrated value sought is read from a graduated scale. The fluid (B) may be a gas, or mercury. The liquid (A) ceases to have a Newtonian rheological behaviour below a determined temperature. It may be a polysiloxane oil.
