Title: Safety device for storage tanks for wine - with U-tube warning arrangement should press. rise too high or fall too low
IPC: B65D90/34
Filed: 1975-12-01
Abstract: Safety device for closed tanks, notably for wine storage tanks with an upper space filled pref. with nitrogen to prevent superficial oxidn. of the wine, comprises a U tube with vertical branches which extend into the chambers, their ends being pierced with holes; an auxiliary tube connects the lower part of one arm (I) of the tube with the upper part of the other arm(II). The tube assembly contains a certain quantity of water so that, in the absence of any press. difference between the chambers, its level is stabilised in the horizontal plane. If for any reason excess press. develops in the tank, the level of the water in arm (II) falls and that in arm (I) rises. When the press. exceeds a certain limit, gas from the tank flowd through the auxiliary tube and rises in the form of bubbles to the chamber from which it is evacuated through the warning whistle. On the other hand, if the press. falls below the ambient the level of the water falls in arm (II) and rises in arm (I) and the air in chamber reaches the entrance of the auxiliary tube; once more the whistle warns the personnel of the press. drop. The whistle operates independently of the flow direction of the gas. The device is cheap, is leak-proof and there is absolutely no risk of an operational failure. Neither an excess or lack of press. can exceed predetermined limits.

Title: Glazing which opacifies under heat or increased light intensity - comprises glass with an interlayer of a liq. gel forming acrylic compsn. and an opacifying agent such as polyvinyl caprolactam
Inventor: RULLIER ROBERT
IPC: B32B17/10
Filed: 1975-12-26
Abstract: Liq. compsn. comprises (a) a material with variable transparency whose optical transmission properties vary as a fuction of the temp. and/or light intensity and (b) a liq., material capable of forming an irreversible gel, esp. at room temp. Pref. the gel forming material is an acrylic polymer based on acrylamide (I) and/or methylolacrylamide (II). A typical gel forming compsn. contains 5-10% (I), 5-10% (II), 0.3-2% ammonium persulphate (III) as catalyst, 0.3-1 % diethylaminopropionitrile (IV) and water to 100%. Such compsns. are liq. and set to an irreversible gel in about 10 mins. at ambient temp. The compsn. is esp. useful as an interlayer between glass sheets to give a glazing material which becomes more opaque as the temp. or light intensity increases. The presence of the gel material overcomes problems associated with prior art materials of the type when used as an interlayer between glass sheets e.g. in large vertical configurations, due to delamination of the joint between the layers due to the hydrostatic pressure of the liq. interlayer.

Title: Measuring radiation absorbed by crystalline sample - by heating in furnace with numerical control and estimating electrons emitted
Inventor: CHUITON RENE
IPC: G05D23/19
Filed: 1976-02-06
Abstract: The invention concerns the control of a furnace partic. in heating a sample from T1 degrees C to T2 degrees C in time to and maintaining it at T2 degrees C for time t1. The control is numerical and the appts. incorporates an oscillator, a frequency divider, a binary counter, a numerical analogue converter, a thermocouple and pyrometer, a comparator and a clock circuit. The frequency divider is connected to the output of the oscillator and to te controller of the N module of the divider. It delivers an output of impulses at frequency f/N, where f is the frequency of the oscillator. The input of the binary counter is connected to the output of the divider and to a stop and return to zero logic. The counter delivers a numerical electrical signal proportional to the total number of impulses delivered by the divider. The numerical signal is fed to the numerical analogue converter which delivers an analogue signal controlling the power circuit feeding the heating resistance of the furnace. The thermocouple transmits a signal, proportional to the temp., to the comparator, which compares it to a reference value corresponding to the temp. level T2 and delivers an output signal to the stop and return to zero logic of the binary counter. The clock circuit, started by the comparator output signal, delivers, after time t1, a return to zero signal to the stop logic of the counter. The appts. is used in measuring the dose of gamma radiation and/or neutron radiation absorbed by a crystalline sample, by heating the crystal in a furnace and estimating the electrons liberated. The estimation is carried out by e.g. a windowless gas-circulation Geiger-Muller counter. The invention enables the achievement of a linear, precise and reproducible temp. rise and an adjustable closely controlled level period. The method is easier to operate, less costly and less subject to drift than existing methods using e.g. integrated circuits.
