Title: Improvements in and relating to lock or latch mechanism
IPC: E05B35/10
Filed: 1936-09-30
Abstract: 481,972. Locks. KAYE & SONS, Ltd., J., and COOPER, S. Sept. 30, 1936, No. 26467. [Class 44] An hotel latch, having a bolt B operated from the inside by a handle through a follower S<1> and from the outside by means of a key through the tail-piece T, has a lever L which is not acted upon by the ordinary key but when operated by a master key enables the latch lock to be check-locked. A stub T<1> co-operates with the projection B<1> to withdraw the bolt and in conjunction with the stub T<2> enables the notches L4 in the ordinary levers to lock the tail-piece T. The ordinary key only operates to withdraw the tail-piece- T and the bolt B, its bits not acting on the lever L. The master key operates the lever L as well as the other levers so that the tail-piece T may be shot and the stub T<1> will contact with another projection B<2> on the bolt B to hold it out, Fig. 2. The nose of the lever L as well as those of the ordinary levers will fall behind the stub T2 and render the tail-piece T rigid. The pillar L<7> prevents the levers falling too low and assists the lever pivot L<6> to take any pressure on the tail-piece. The ordinary key cannot now unlock the door until the master key has been used as it has no effect on the lever L. The elongated slot L5 permits the tail-piece T to be moved back although the lever L is not operated. The curves L2, L<3> are cut to suit the bits of the key and to make these levers reversible. The bolt B is also made reversible. Specification 355,618 is referred to.

[Also in Division F1] A convertable radial-flow fan for providing vertical and horizontal propulsion of an aircraft comprises a rotor disc 10 carrying fan blades 20 and turbine blades 14. The turbine is of transverse-flow type and is driven by exhaust gas from a prime mover entering at 16 and exhausted at 19. Two sets of stator blades 15 extending over nearly half the circumference direct the gas on to the blades 14 during its successive radially inward and radially outward flows through the blades 14. The fan also is of transverse-flow type when providing horizontal propulsion, drawing in air through a forward inlet 22 and expelling it through a rearward outlet 23. Sets of inlet guide blades 25, 26 and outlet guide blades 24 each extend around the circumference to an angular extent of 90 to 180 degrees. For vertical propulsion, the fan is changed to radiallyinward-flow operation, drawing in air through both passages 22, 23 and expelling it through a central opening 28. For this purpose louvres 29 normally closing the opening 28 are opened and the guide-blades 24 in the passage 23 and the guide blades 26 are turned through more than 80 degrees to revise their functions. The fan rotor blades 20 are of impulse, i.e. symmetrical, form so that they are equally suited to radially inward and radially outward flow. The inlet guide vanes 25 may be omitted. Preferably, a separator 30 is provided between the passages 19 and 23. Three fans may be arranged as shown in Figs. 4 and 5 (not shown) with one fan under the fuselage and one under each wing, to provide a triangular arrangement for attitude control.

Title: Improvements in devices for discharging loads from aircraft
IPC: B64D1/02
Filed: 1930-09-06
Abstract: 368,699. Dropping loads from aircraft. FABBRICA ITALIANA MAGNETI MARELLI, 22, Corso Venezia, Milan, Italy. Sept. 6, 1930, No. 26677. Convention date Sept. 7, 1929. Void [Published under Sect. 91 of the Acts]. [Class 9 (ii).] A device for releasing loads from aircraft is provided with an electric signal actuated by a switch which is operated when the load is discharged. According to one oonstruction the load 4, as shown in the Figure, is carried by the arm 2 of a pivoted hook 1, 2 which is normally retained in a position to support the load by a locking arm 5 pivoted on a pin 6. The arm 5 is normally engaged by a pivoted lever 7 which is adapted to be attracted by an electromagnet 8. The electromagnet is shunted from a feeding circuit 10, 11 by wires 21, 22, 13, a switch 14 being inserted in the latter. The wires 21, 22 are normally connected by a pivoted switch 20 an arm of which lies in the path of the limb 5<1> of the locking arm 5. The signalling device comprises a lamp 17, or other signal, shunted between leads 11, 19 of the feeding system by wires 23, 22. In operation, switches 14, 15 are closed and the signalling device is energized. On closing a further switch 16 the electromagnet. 8 is energized and attracts the lever, thus releasing the arm 5 and hence the hook 1, 2 to discharge the load. The oscillation of the arm 5 in this movement opens the switch 20 thus breaking the circuits of the signalling device 17 and the electromagnet 8.
