    Abstract: Fluid control circuit for controlling the pressure applied by jacks (12) to an article such as an aircraft wing undergoing testing. Fluid supply lines (18, 20) carry hydraulic fluid to and from the jacks (12) under control of a main control valve (23). Locking means (16) in the form of cutoff valves (25, 26) are provided to close the supply lines (18, 20) to fluid flow if a fault condition is detected. The cutoff valves (25, 26) are pilot operated and normally hold lines (18, 20) open. Pilot control valve (31) controls the supply of pilot fluid to the cutoff valves (25, 26). Dump lines (37, 38) are opened to pressure relieving fluid flow when dump control valves (39, 40) are open. Bleed control valves (41, 42) control the rate of such pressured relieving flow. Auxiliary valves (47, 48) prevent leakage flow back through main control valve (23) when the dump lines (37, 38) are open.

    Abstract: Pyrometre a infrarouge permettant de controler le chauffage rapide de materiaux a l'aide de lasers CW ou de faisceaux d'electrons. Les rayons infrarouges irradies par le materiau sont separes en deux longueurs d'ondes tres proches et l'on obtient des signaux representant les deux longueurs d'ondes. Ces signaux sont ensuite traites dans un circuit electronique, la valeur de l'un des signaux etant maintenue sensiblement constante par regulation alors que la valeur de l'autre signal est influencee par sensiblement la meme regulation que celle qui est appliquee au premier signal, les valeurs de signaux resultantes etant ensuite traitees par des moyens produisant un rapport d'une des valeurs divisee par l'autre valeur. Ceci constitue donc une mesure de la temperature du materiau. Une roue de partition pour un spectrometre a infrarouge est egalement decrite. La roue (3) comporte une pluralite de filtres a infrarouge s'etendant dans le sens de la circonference, de longueurs d'ondes alternees (1, 2).

    Abstract: A control system for an apparatus, such as a machine tool (100), for forming a straight configured contour having co-ordinates in at least two directions (X, Y, Z). The apparatus incorporates a workpiece support (102), a contour forming means (107), and incremental drives (M u, M u and M u) to effect relative movement between the support (102) and the contour forming means (107). The components of the straight configured contour in each of the directions (X, Y and Z) are reduced to the number of nominal increments corresponding to a predetermined distance along the contour. A continuous feed of input pulses is provided to a computer for continuous counting in respect of each direction. A drive pulse is fed to a respective incremental drive (M u, M u or M u) to effect movement in the respective direction (X, Y or Z) each time a predetermined number of respective input pulses have been counted, the predetermined number being inversely proportional to the number of nominal increments relevant to the direction. A curviliner contour may be formed from successive straight configured contours.

    Abstract: Continuously - excited lasers of the CO u mixing, and supersonic CO, types. There is specifically disclosed a method, and a laser apparatus, for producing a repetitively pulsed output, in which a stream of excited gas, of the type having a relatively long excitation life, is produced, stored and subsequently transferred, in the form of pulses, to a power extraction zone incorporating a resonator. In one example the gas laser is a supersonic CO laser in which the CO is excited in the excitation zone and is, after storage, transferred under supersonic conditions to the resonator. In the main example the gas to be excited is N u which is initially transferred to a storage chamber provided between a rotatable storage cylinder (16) and an axial supporting shaft (18) therefore, and thereafter the N u is transferred through holes (17) in the storage cylinder (16) which align during rotation with slots (20) through a surrounding fixed cylinder (19) to allow pulses of excited gas to be transferred to the power extraction zone (12) where it is mixed with CO u and He, entering through supply tubes (23), and to which it transfers its excitation before flowing to the resonator.

    Abstract: A gating circuit for gating a minimum duration input signal on one of a plurality of input lines (10) to a respective output line (16). The input lines (10) are coupled to a latch (15) comprising flip-flops and the latch is enabled when a signal is applied to a clock input (18). The input lines (10) are coupled to a verifier circuit (25) which includes a verifier gate (27) receiving direct and delayed signals from a NAND gate (32) connected to the input lines (10). The verifier gate (27) applies a signal to the clock input (18) when both inputs (28, 29) are simultaneously receiving a signal so that signals less than the minimum duration do not result in a signal at clock input (18). The NAND gate (41) applies a signal to locking gate (44) when any one output (16) of latch (15) is energised, and the output (47) of locking gate (44) holds a disabling signal on clock input (18) so that only the first input signal on a line (10) will be latched. A reset means (50) including reset gate (51) and switch (53) enables resetting of the latch (15).
