Abstract: Position-sensitive radiation detector provided with a semiconductor structure comprising a wafer of semiconductor material of a first conductivity type having two principal-surfaces situated at relatively short distances from each other, the dimen­sions of which are sufficient to enclose the desired radiation detection surface. An electrode structure is formed on the wafer surfaces such that when suitable voltages are applied to said electrodes two drift fields are generated in the depleted body of the wafer. Detector/amplifier circuits are connected to selected electrodes of the electrode structure to emit, during operation, a start signal at the instant at which charge carriers are generted in the depleted part of the structure as a consequence of incident radiation or elementary particles, and a to emit a stop signal at the instant when charge carriers reach a detection electrode of the structure after propagation through both drift fields.

This control device, in which a target value of the pressure difference (delta P) between the discharge pressure of the hydraulic pump and load pressure of the actuator is preset, drives the means for varying displacement of the hydraulic pump according to a deviation delta (delta P) between the pressure difference and the target value and controls the discharge quantity of the pump so that the pressure difference is kept at the target value. The control device is provided with: first means (202-204) for inputting at least one value which affects the ratio of variation in the discharge pressure of the hydraulic pump to variation in the displacement of the hydraulic pump to determine a control gain (Ki) for variation speed of the displacement on the basis of the value which affects ratio variation. Second means (205-209) controls displacement varying means of the hydraulic pump on the basis of the control gain determined by the first means and pressure difference deviation. @(116pp Dwg.No.9/42)@.

Abstract: A crew protection system designed to isolate an aircraft crew and provide a means for safely evacuating an aircraft, particularly hypersonic vehicles, in emergency situations. The crew compartment is designed within the forebody of the main vehicle. The forebody is designed so as to separate cleanly from the main vehicle as by generation of a circumferential structural break, in the event of a catastrophic failure or explosion of the main vehicle fuel tank. In the event of such an uncommanded failure of the main tank and propellant combustion, resulting in the above noted structural failure, the resultant pressure impulse thrusts the forebody containing the crew compartment clear from the remainder of the vehicle. The provision of a system of baffles in the forebody between the crew compartment and the fuel tank, and the shape of the forebody and the materials used in its construction mitigate the effects of the blast pressure impulse on the crew. The forebody is also designed to be stable during the transient period immediately following the blast and the subsequent free fall of the forebody, permitting the crew to safely evacuate the crew compartment and forebody at a preselected altitude.

Abstract: A process is described for cleaning a gas, which contains combustible components and also carbon dioxide and sulphur compounds, in particular H2S, by scrubbing in a scrubbing zone with a scrubbing solution, which is regenerated and recycled. For regeneration, the scrubbing solution is depressurised, stripped and heated in a heat regeneration. Part of the H2S-rich waste gas from the heat regeneration is burnt in a combustion chamber with oxygen, oxygen-containing gas or air, producing a gas mixture in the combustion chamber having a temperature in the range from 1000 to 2000 DEG C, which mixture contains, as elementary sulphur, at least 30 mol% of the sulphur fed to the combustion chamber and the components H2S and SO2 in the molar ratio from 4:1 to 1:1. The gas mixture is cooled to below the dewpoint of sulphur, elementary sulphur condensing out is separated off and the gas mixture is heated to temperatures of 180 to 280 DEG C, prior to subjecting it to a catalytic hydrogenation and/or hydrolysis, the remaining content of SO2 being substantially converted into H2S. At least a part of the gas thus treated is, as H2S-containing residual gas, contacted with scrubbing solution. <IMAGE>
