Title: Improvements in and relating to aircraft with freely rotative wings
IPC: B64C27/02
Filed: 1931-06-12
Abstract: 379,420. Aircraft with rotary wing systems. LA CIERVA, J. DE, Bush House, Aldwych, London. June 12, 1931, No. 17119. [Class 4.] In an aircraft of the type having a normally wind-driven rotary wing system and with means for taking off power from forward propelling means to supplement the action of the wind in driving the rotor when its rotational speed tends to fall below a minimum value, at least two propulsive airscrews are provided on either side of the craft and are so arranged with respect to the movable control surfaces comprising ailerons, elevators and rudder or rudders that substantially every part of all such surfaces lies within the slip-stream of one or other airscrew. Fig. 1 shows an aircraft of the above type having outboard engines 28, 29 mounted on wings 15 and driving propellers 31, 32 of adjustable pitch. The axes of the airscrews are arranged to converge rearwardly bringing ailerons 17, rudder 25, tail planes 26, elevators 27, and the greater part of fin 24 within the slip-stream. Engine 29 which is arranged on that side of the craft on which the blades of rotor 14 are retreating is fitted with rotor driving means comprising a shaft 36 arranged within the thickness of wing 15 coupled by bevel gearing to an upright shaft 38 housed within a hollow rotor-supporting mast 12. Shaft 36 is connected by bevel gearing to the engine crank shaft and shaft 38 to a hub member 39, a free-wheel device being included in the transmission permitting the rotor to overrun the driving shaft at normal speeds but to be driven when the speed tends to drop below a pre-determined minimum. The airscrew may rotate in opposite directions and means may be incorporated to throttle down or cut out one engine if the other cuts out unexpectedly. Main landing wheels 19, a single front wheel 23, and a tail skid 22 provide two stable ground positions cc, dd, respectively, the centre of gravity g falling within the wheel base in either position. Position cc is employed for take-off and position dd for pulling up on landing, since in this position the angle of incidence of the rotor is approximately zero.

Title: Arrangement and method for the photographic production of sound films
IPC: G11B7/00
Filed: 1937-06-21
Abstract: 497,713. Optical sound recording apparatus. BORMANN, 0. June 21, 1937, Nos. 17254 and 17255. Convention dates, June 22, 1936 and July 25, 1936. [Class 40 (ii)] [Also in Group XX] In the printing of copies of a sound record on to an endless film, wherein the copy takes the known form of a continuous helical track extending several times round the film, or of several tracks parallel to the edges of the film and united to form a continuous track by short inclined tracks, a wide original record of the variable density type is used, or a wide image of a narrow original is projected as by a cylindrical lens on to the printing gate, and a narrow stop in front of the gate is displaced either continuously or intermittently in a transverse direction during the printing operation. Intermittent feeding of the stop may be effected automatically by lever mechanism engaging a notch in the endless film after each complete passage of the film through the gate. The stop may be formed in a transverse slide ; or, as shown in Fig. 2, it may consist of a slit 22 of adjustable width extending across the gate, over which is mounted a rotatable disc 17 provided with one or more narrow spiral slits 19, or a disc similar to 17 may be used, provided with a series of spirally-arranged apertures of e.g. square shape. From the endless film so produced a second copy may be made in which the record is printed several times in juxtaposition on a wide film ; this second copy is used as a master for printing a series of copies each of which may be slit longitudinally into several record films each of which is joined to make it endless. Alternatively, instead of employing a single stop in the first printing, several spaced stops of the same or different or adjustable size may be used as shown in Fig. 3 in the transversely-slidable plate 34, so that the first copy bears several complete narrow records in juxtaposition, and may either itself be slit longitudinally into several narrow films each bearing a complete record, or may be used as a master for producing copies which may be so slit. If the stops are of the same size, the intensity at each may be varied by a grey filter. The method described with reference to Fig. 3 may also be employed in recording sound on a sensitive film. Specifications 449,633, [Group XX], and 453,890 are referred to. The Specification as open to inspection under Sect. 91 does not limit the invention to endless copy films, and states also that if the original record does not extend across the whole width of the film, the original film may also be transversely displaced in the printing gate after the stop has traversed the full width of the record. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to devices for initiating the shuttle exchanging and thestopping of a loom respectively
IPC: D03D51/00
Filed: 1944-09-19
Abstract: 586,214. Loom stop-motions. AKT.-GES. DER EISEN-UND , STAHLWERKE VORM. G. FISCHER. Sept. 19, 1944, No. 17901. Convention date; Sept. 22, 1943. [Classes 142 (i) and 142 (iii)] In a loom in which the starting handle 15 can be disengaged from its weaving setting by a lever 1 pivoted on the breast beam, the handle is arrested in the stopping position, Fig. 2, on weft or warp breakage, but is allowed to move beyond this position on weft exhaustion to initiate automatic weft replenishment, Fig. 3 ; alternatively, weft breakage may initiate replenishment. When the weft fork 19, (Fig. 2), which is mounted directly on the lever 1, is operated by the weft hammer 10, the lever is displaced against a spring 18 and forces the handle 15 out of the notch 21, a catch 14 being held against a stop 17 on the lever by a spring 37 so as to block the path of the handle. At the same time, the arm 30 of a three-armed lever pivoted on the lever 1 displaces an arm 32 to interrupt the take up motion. On warp breakage, a nose 25, Fig. 5, rises into the path of a nose 27 on the slay, whereupon the three-armed lever 23, 28, 30, is moved bodily, causing the lever 1 to stop the loom, and is also turned to the chain line position of Fig. 5, so that the arm 30 clears the arm 32 and the take-up is not interrupted. When weft exhaustion is detected by a spool feeler, a rod 7, Fig. 3, supported by a lever 11 slides into the path of the hammer 10, whereby the lever 11 is turned about its fulcrum 4 on the lever 1 to withdraw the catch 14 from the path of the handle 15. Continued movement of the hammer 10, after the bowed portion of the lever 11 has contacted the boss of the catch 14, turns the lever 1 to the position shown in Fig. 3 and the handle 15 moves to the full extent of its travel to initiate weft replenishment. Whilst this occurs, the catch 14 is held by a pawl 35 operated by a fixed stop 38. The lever 11, in turning about its fulcrum, acts on the arm 28 of the three-armed lever, Fig. 5, thus raising the arm 30 to prevent interruption of the take-up motion. In modifications, the pawl 35 may be omitted or may be spring-loaded towards the catch 14 and a second pawl, mounted on the pawl 35 and co-acting with a fixed stop, affects disengagement of the pawl 35 from the catch 14 when the lever 1 swings rearwards. The catch 14 may pivot on the breast beam or may be integral with the lever 11, which may pivot on the lever 1 or on the breast beam. To initiate weft replenishment when the weft breaks, the weft fork 19 is carried by the lever 11 instead of by the lever 1.
