[Also in Divisions B8 and F1] An aircraft, e.g. a crane helicopter, has hydraulically operated fasteners 4 connected in series, each mounted on a single telescopic lifting arm 5 at the front, and on three converging lifting arms 7, 8, 9 at the rear. The front arms may be connected to alternative points on the fuselage, as at 6, to accommodate loads of differing size. Each fastener comprises jaws (35, Fig. 6, not shown or see Division B8), actuated by movement of a plunger 34 between abutments on the jaws. The plunger is operated hydraulically (through connections 39, 40) or in emergency mechanically by a lever (36). The lifting arm is integral with the fasteners and is raised (contracted) by fluid introduced through an inlet (32) into a chamber (31). The arm is extended by compressed nitrogen in a chamber (30) separated from the chamber (31) by a piston. The arm is locked in the raised position by hydraulic and mechanical locks. Reversing valves (41, Fig. 7) each controlling the supply and return fluid lines (43, 44) to the arms, are connected in parallel, and a single reversing valve (42) connects the lines to the circuit containing the fastener actuators in series. One of the fastener actuators also has an hydraulic lock (46). The valves are electrically operated from a control panel plugged into the aircraft from the ground.

In a rotary fluid-flow meter for liquefied petroleum gas a pressure-regulating valve 7 in an inlet opening 5 is actuated by downward deflection of a diaphragm 17 in response to changes in the gas pressure in a chamber 16' that is connected to an outlet passage 4 by a passage 19, the valve 7 being carried by an axially-slidable member 3 that is linked to the said diaphragm by a lever 12 and a rod 18. Gas entering a chamber 1 containing said lever passes into the passage 4, which contains rotatable vanes 8, through a pressure-reducing nozzle 2, the vanes being coupled to a register or counting device 10, 11. The diaphragm 17 is loaded by a spring 25 abutting an adjusting nut 26 so that the pressuresensitivity of the diaphragm can be regulated.

The range is dependent on the ratio of the resistor values 31:32 or 31': 32'. The enthalpy signal 30 from the outside air is connected to a signal repeater 35 having a fluid-pressure supply 45 and an output line 49 communicating with a comparator 36 which also receives an enthalpy signal 29 for the return air. The output from the comparator 36 is fed with a demand signal 11 to a diaphragm valve to control the actuator 7. The temperature sensors 16, 18 may be coupled through a separate repeater 37 and a comparator 38 to a point 54 to provide a signal to the actuator 7 and the arrangement is such that outside air will be supplied to the duct 1 if its dew point is below 55F and its temperature is below the return air. If the dew point is above 55 degrees, outside air is selected as the supply only if it has a lower enthalpy than the return air. The actuator 7 at each operation turns one set of dampers to maximum flow and the other set to minimum flow but may be connected to the output (82), Fig. 4 (not shown) of a proportional control in which enthalpy signals from the return and outside air ducts are fed to the opposed nozzles (77, 78) of an impact modulator. The discharge duct 1 contains a cooling unit 8 supplied by a compressor 9 under the control of a valve 10 responsive to the demand signal 11.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 5, 1934]. [Class 98 (ii)] In projecting a colour-record lenticular film, either for copying or for exhibition, a colourselecting projection filter is used (or a corresponding diaphragm if a filter is not used in projection-printing) which differs in size, centring, or relative areas or permeabilities of its colour bands, from the filter used in taking the film, so as to modify the luminous rays according to the distribution of the intensities of the monochromes in the diffraction solid corresponding to the projected photograph. As described, the filter or diaphragm is placed at the distance from the film which is theoretically correct for projection, but is modified by making its size half that of the taking filter, with the widths of the bands correspondingly reduced (Fig. 2), or with the central band of full width and either masked over half its area (Fig. 3) or of halved permeability over its whole area (Fig. 4). The colour bands may be decentred with regard to the bands of the theoretically-correct projection filter, and the arrangement of the bands may be dissymmetrical.
