Title: Improvements in aircraft
IPC: B64C29/00
Filed: 1960-03-29
Abstract: 909,923. Vertical take-off and landing aircraft. HILL, D. March 27, 1961 [March 29, 1960], No. 11075/60. Class 4. A vertical take-off and landing aircraft includes one or more power units, the thrust from which is reversible for take-off and landing, and has a wing hinged to the fuselage so that for vertical take-off and landing the wing can be moved into a vertical plane, trailing edge uppermost, the personnel carrying part of the fuselage remaining substantially horizontal. Fig. 1 shows an aeroplane in normal forward flight, a delta wing 6 and fuselage tail portion 2 being hinged on an axis 7 to a main fuselage portion 1 carrying fixed stabilizers 4. A rudder 3, ailerons 10, and elevators 5 are fitted. Wing tip gas turbine engines 8 are mounted so as to be rotatable about axes 9. Fig. 4 shows the take-off and landing configuration, in which the wings take up a vertical chord attitude under the control of hydraulic jacks normally faired within doors 12, Fig. 1. The propulsion engines 8 have been rotated through 180 degrees to provide upward thrust, and a single pilot's control may be provided for orientation of the wings and engines in a predetermined interrelated manner. Undercarriage legs 16 having castoring wheels or shock absorbers, extend from the wing leading edges, the wheels being receivable in covers 20 pivotable on axes 21. A castoring nose wheel 13 and tail wheel (not shown) extend from the fuselage portion 2. After take-off, the configuration of Fig. 1 is assumed, height being lost in the process as the aircraft temporarily assumes a diving attitude. During the vertical take-off and landing, the wing is preferably maintained edge on to the wind to minimize drift, control being obtained by rotating the engines 8 in opposite senses to set up a torque about a vertical axis which may also be used for roll control in normal forward flight. Control about the main fuselage fore-and-aft axis is obtained by varying the thrusts of the two engines differentially. Fig. 12 shows an embodiment in which contra-rotating propellers 24 surround the rail part of the fuselage, each propeller blade being telescopic so that the swept disc may be of greater diameter during vertical flight than during horizontal flight. In the transition stages, the blades are rotated through 180 degrees about their pitch change axes, and the directions of rotation are reversed, to provide thrust reversal. Each propeller may be driven from an engine through a pinion and ring gear, each pinion being disengaged from its associated ring gear and engaged with the other, when reverse rotation is required. In either embodiment, the aircraft may be tilted during take-off or landing by transfer of fuel from one wing tank to another, or by retraction or extension of only one undercarriage leg immediately after take-off, or during landing. Means is provided for locking the wing relatively to the fuselage.

Title: Improved feeding device for strip material
IPC: B21D53/50
Filed: 1944-06-14
Abstract: 597,510. Feeding webs. AERO ZIP FASTENERS, Ltd., and ENGEL, E. June 14, 1944, No. 11344. [Class 100 (i)] [Also in Groups XXII and XXV] A device for intermittently feeding strip material such as strip metal, particularly intended to be used in the manufacture of interlocking members for sliding clasp fasteners, comprises a reciprocatable feed member including a member pivoted to a carrier and arranged for gripping and locking the strip thereto, and means for actuating the feed member including means for urging it in one direction to assume the end position of a stroke and a lever or the like reciprocatable in a direction substantially perpendicular to the first direction and contracting the locking member slidably so that the components of the impelling force in the two directions vary during each half cycle in such a manner that the locking member pivots on the carrier into locking position before the feed stroke begins and pivots in the opposite direction to release the strip before the return stroke begins. As shown the feed member consists of a slide 12 mounted between guides 14 and having a recess 13 to receive the strip, and a locking lever 11 pivoted to the slide 12 at 18 and consisting of two arms 16, 17 with a rod 21 screwed into the arm 17 and engaged by an adjustable compression spring 23 secured to a fixed rod 25. A horizontal lever 27 is movable about a pivot 28 by a cam 30, one end of the lever contacting a roller 26 mounted in the arm 16. The bottom of the arm 17 is cam-shaped at 20 to lock the strip in the recess 13 when the end of the lever 27 engaging the roller 26 is lowered. As this end of the lever 27 is lowered further the spring 23 urges the feed member across to execute the feed stroke. When the end of the lever is raised, since its point of contact with the roller 26 is near the bottom of the roller, the horizontal component of the thrust of the lever is small and the locking lever 11 is rotated to release the strip before the whole feed member makes the return stroke. Adjustable stops 300, 310 are provided to limit the strokes so as to adjust the length of feed. In modifications the spring 23 may act to effect the return stroke instead of the feed stroke in which case the arm 16 extends the direction opposite to the feed. The lever 27 may be replaced by a cam, and the spring 23 may be replaced by hydraulic pressure means.

IPC: H04Q3/42
Filed: 1957-04-09
Abstract: 852,951. Automatic exchange systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. March 27, 1958 [April 9, 1957], No. 11567/57. Class 40 (4). The availability of a wanted subscriber is signalled to a register which analyses the signal and causes the originating register to return appropriate tone to the calling subscriber. The invention is applicable to the type of system described in Specification 843,175, wherein high-speed hunting is employed to set up a route before the necessary switches are operated to set up the speech path. A junction relay set JRS is thus seized at the terminating exchange and the necessary group selectors and final selector operated. The final selector FS now returns ringing, busy or N.U. tone to JRS. The tone is amplified at A, rectified and joined to a sampling pulse on lead TCN, the length of the sampling pulse corresponding to the time taken by the corresponding register on a magnetic drum to pass the reading-writing head. Thus for the sampling periods during which tone is received an output is obtained on lead TS. The proportion of tone to silence in any 3-second period is different for each of the three types of signal. For each time tone is detected during a 3-second period, one is added to a number previously entered into part of the register on the magnetic drum and each time there is absence of tone one is deducted. At the end of the count the number registered is used to set up a combination of electronic relays MDMF (not shown) to return an appropriate signal P (not shown) over the high-speed signalling path to the originating exchange. Appropriate tone is then returned to the calling subscriber. Only if this is ringing tone is the necessary switching path established.
