Abstract: The danger of explosion due to decomposition of high-pressure industrial process gases, such as ethylene, is reduced by maintaining in an inert atmosphere at least part of an evacuation system included between a pressurized vessel within which the decomposition may take place, on the one hand, and the atmosphere, on the other. The evacuation system to the atmosphere for the gases contained in the high-pressure vessel, includes (1) an evacuation pipe adjacent to the vesel; (2) a safety means separating the evacuation pipe from the vessel; (3) a sealing means located in the evacuation path of the gases and occupying the entire cross-section of the evacuation pipe; (4) a first gas supply circuit connected by a pipe to that part of the evacuation pipe that is located between the safety means and the sealing means, and means for the first supply pipe to control the volume of gas supplied by the first supply circuit; and (5) a second gas supply circuit connected by a pipe to the sealing system, and means for the second supply pipe to control the volume of gas fed by the second supply circuit. The apparatus is useful for the recovery of decomposition products for the purpose of averting atmospheric pollution, as well as for reducing the risk of explosion.

Abstract: A processing unit is interconnected with an operator console by an interface bus (13) of finite capacity and transfer of information is normally in a preferred direction from the processing unit to the console. Provision is made to transfer other information from the console to the processing unit without impacting the bus by utilizing a normally continuously operating counter (11) in the processing unit and a comparator (12) in the console. The console comparator (12) compares count signals (on 13a) from the counter (11) with locally generated digital signals (on 14) representative of keyboard depressions and provides a stop signal to the processing unit counter over a single line (15) when an equal compare occurs. The processing unit can then interrogate the counter (11) at a convenient time and confirm a valid entry by operating indicators, such as visual and/or audible means in the console and the interface bus capacity is not impacted by the transfer of the other information from the console.

Abstract: The invention relates to pressure relief valves of the kind in which there is a valve member (34) in the form of an inverted cup with its skirt normally resting on a valve seat (32) around an aperture (28,30) the valve member (34) being movably away from the seat to open a passage through the aperture (28,30) and in which an obturator (22) is located within the valve member (34) and fixed relatively to the valve seat (32). In this kind of valve, the obturator (22) restricts access of the fluid to the area of the valve member (34) on which the fluid pressure acts, and this reduces chattering. Said valve includes a by-pass conduit (54) leading from an auxiliary inlet (52) separate from the valve aperture (28,30) to the space (56) between the closed end of the cup shaped valve member (34) and the obturator (22).

Abstract: n pulse width modulation circuits for supplying amplitude modulated current to the anode of the R.F. stage of a high power radio transmitter, problems arise from carrier compression and from the need to protect the voltage source against excessive currents in the event of one or both of the switching valves breaking down. The protection circuit needs to handle an extremely large power: namely all the power supplied to the anode. 
     The invention overcomes this problem by using two voltage sources (1, 9) one (1) of which provides carrier power whilst the other (9) drives a pulse width modulation amplifier (8) which modulates the carrier. Varying demand for power to the amplifier (8) thus does not effect the carrier. Therefore carrier compression is reduced. Also, only that voltage source (9) which feeds the amplifier needs a sophisticated fast acting protection system (11, 12) and since this does not supply all of the power to the anode the protection system is able to operate reliably.

Abstract: Polyurethane polymer polyols can be prepared by reacting a hydroxyl-containing amine (e.g. ethanol-amine), a polyetherpolyol having a molecular weight of 2000 to 8000, and a less than stoichiometric amount of an organic polyisocyanate. The molar ratio of hydroxyl-containing amine to polyether polyol is from 0.5:1 to 3.5:1. The molar ratio of active hydrogen (in hydroxyl-containing amine and polyol) to isocyanate is from 1.4:1 to 3.5:1. 
<??>In a preferred embodiment, the stability of the polyurethane polymer polyols is enhanced by adding a secondary amine. 
<??>Polyurethane foams obtained by reacting the polyurethane polymer polyols with more polyisocyanate have generally better properties (e.g. tensile and tear strength, elongation and compression) than foams produced directly from hydroxyl-containing amine, polyether polyol and a stoichiometric amount of polyisocyanate
