Title: Dissolved acid gas estimation - by thermally decomposing basic soln and measuring gas flow rate
IPC: G01N7/14
Filed: 1971-06-01
Abstract: Acid gas in base soln., e.g. H2S in diethanolamine (produced when disulphurizing natural gas), is released by thermal decomposition, at pressure using superheated steam pipes, or using electrical heating at atmospheric pressure. Gas flow rate is then measured, e.g. by an orifice meter, to estimate acid gas concn. by comparison with solns. of known strength. Soln. may be sampled from a main stream; and passed to a column with a reboiler, liquid outflow being under level control, water and base are condensed from distillate, gas is discharged to atmosphere under pressure control at measured flow rate. Interfering gases may be eliminated by selective adsorption, or selective estimation may be employed.

Title: Cooling system - for gas cooled reactor fuelling machine
IPC: G21C15/12
Filed: 1971-09-29
Abstract: A gas cooled reactor fuelling machine cooling system in which the main reactor coolant is circulated down through the machine during fuel unloading. Coolant flow in the fuel channel being unloaded is adjusted by the channel gas to maintain balanced flow and pressure conditions. the fuel is stored in a magazine in the machine and during transport from the reactor to an irradiated fuel disposal facility, a circular and cooler integral with the machine maintains gas cooling to dissipate decay heat. Thus continuous gas cooling is maintained during the whole fuel cycle. Economic advantages accrue from on-load fuel charging and from use of the main reactor gas coolant as cooling medium during reactor operation. The machine is pressurised and shielded to obviate gas escape or irradiation leakage.

Title: Fire extinguisher valve for use in measuring press. - has tube with two annular valve seats blocked by ball
IPC: A62C13/00
Filed: 1973-07-27
Abstract: Valve to be fitted to wall of fire extinguisher, to which a pressure gauge can be attached to measure the internal pressure.

Title: Bullet-proof body garment - has layers nylon fabric strips interconnected only at edges, and cryogenically treated
IPC: F41H1/02
Filed: 1973-12-17
Abstract: The bullet-proof body garment has a flexible cushion of several layers, e.g. of one or two dozens strip of fabric, oppositely directed and interconnected at one edge, with no effective interconnection between the edges, so that each strip can bend. The fabric is of closely-woven type of heavy nylon yarns, e.g. 1050 denier. The cushion is fitted and held to the body part to be protected, to stop bullets which strike against the cushion. Preferably the nylon material has a molecular structure resulting from linear alignment of the molecules, and is subsequently exposed to a cyrogenic temperature near absolute zero for a short time, e.g. 1 hr. Preferably the treatment increases the ability to retain bullets. Flexibility is sufficient for normal wear, and the weight for complete protection, e.g. 2.5 kg, is tolerable.

The rate of natural ageing of the cyanate ions, i.e. their conversion into carbonate ions at a temp. between the m.pt. of the salts and 700 degrees C, does not exceed 1% per day which has neve been achieved hitherto.
Patent FR-2240087-A1 (FR)
Title: Trimming rubber invested steel cord layer - with spring mounted adjustable knives acting on curved surface without pressure
IPC: B29D30/46
Filed: 1974-07-31
Abstract: The side edges of a rubber invested layer of steel cords, moving intermittently lengthways, are trimmed by two cutting devices acting on the inside of the edging cord at each side as the layer runs over a guide roller in the tensionless condition, only the edging wires being under load as they are drawn off at an angle and wound up. When the running of the layer is stopped for cutting off to length, the temp. of the knives is immediatley dropped to ambient, and on restarting is lifted at once to the operating temp. Arrangement ensures accurate trimming of the edge of the steel cord layer and thus accurate subsequent splicing.
