Title: Apparatus for landing aircraft
IPC: B64C25/42
Filed: 1954-08-27
Abstract: 754,405. Shortening landing run for aircraft. GOODYEAR TIRE & RUBBER CO. Aug. 27, 1954 [April 13, 1954], No. 24933/54. Class 4. Means for shortening the landing run of aircraft comprise apparatus for sensing complete touch - down and mechanism operated by the sensing means for quickly raising the landing flaps to transfer the weight of the aircraft from the wings to the landing wheels and applying the wheel brakes. Additional apparatus may be used to automatically depress the elevators to further reduce wing incidence and lift. The flaps 9 are connected by linkwork 12, 13 to an hydraulic motor 14 controlled by the pilot for normal operation of the flaps. Aft of the motor 14 the rod 13 is pivotally connected to one end of a lever 15, mounted on a fixed pivot 16 and connected at its other end to a pistonrod 22 of a jack 20. The cylinder of the jack is connected by a pipe 28 to a solenoid-operated valve 27 which places the cylinder selectively in communication with a pipe 26 connected to a pump 24 or a pipe 30 exhausting into a liquid reservoir 25. A branch pipe 40 from pipe 28 and pipes 42, 43 place the brakes on the landing wheels 2, 3 in communication with the pump 24. Micro switches 32, 33, 34 actuated by cams 35, 36, 37 on the respective landing legs 5, 6, 7 are placed in series through a power source 38 and an arming switch 39 with the solenoid 31 on the valve 27 so that on complete touchdown as sensed by partial compression of all undercarriage shock absorbers the solenoidoperated valve places the jack 20 in communication with the pump 24 whereby the flaps 9 are retracted rapidly to reduce wing lift and increase the wheel loading so that the brakes may be applied automatically more heavily than would otherwise be possible. An additional mechanism (Fig. 1A, not shown), is described for simultaneously lowering the elevators to cause the aircraft to pitch downwardly on landing to effect a reduction of wing lift additonal to that caused by raising the flaps. To facilitate such downward pitching the shock absorber of the nose undercarriage may be made relatively soft. Two alternative arrangements for introducing the operation of the jack 20 into the flap-operating linkwork and an electrically-operated jack arrangement are described.

Title: Improvements in change speed gearing
IPC: F16H3/08
Filed: 1934-08-30
Abstract: 445,183. Change - speed gearing. BRITISH CELANESE, Ltd., 22, Hanover Square, London, KINSELLA, E., ADDY, C. W., and PRATT, J. G., c/o British Celanese, Ltd., Spondon, near Derby. Aug. 30, 1934, No. 24987. [Class 80 (ii)] Speed - changing transmission apparatus comprises at least two pairs of fixed centres, such as 9, 12 and 12, 15, the centres of each pair being at a fixed distance apart and adapted to receive pairs of intermeshing pick-off " gears in series so as to constitute a train of gears giving a compounded gear ratio, and a set of interchangeable gears from which said pairs of gears are selected. Thus gears 10, 11 connecting the centres 9, 12 are one pair, and gears 13, 14 connecting the centres 12, 15 are another pair. A numerous set of disconnected separate gears is provided forming pairs of gears interchangeable with the pairs in use. Standard gears are used and, in addition, auxiliary gears cut from blanks of the same sizes as standard gears but having one tooth more or less than the standard gear, by which one gear of a pair may be increased by one tooth without reducing the other gear of the pair by a tooth. The effect is to obtain a very fine gradation of ratios all positive-driving. Thus one set of gears may range from 30 to 70 teeth with a constant sum of 100 teeth in the pair. A range of 41 ratios from 30/70 to 70/30 is obtainable for this pair. The other set may range from 30 to 80 giving a like range of 51 ratios. The total combined ratios with standard gears alone is thus about two thousand in number, but, by the use of the auxiliary gears, the total number of different practicable positivedrive ratios is about eighteen thousand of range 9/56 to 56 /9. Specification 445,184 is referred to.

Title: Improvements in or relating to cathode ray tube display apparatus
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: G01S7/12
Filed: 1951-11-01
Abstract: 733,553. Pulse radar; cathode-ray tube operating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 24, 1952 [Nov. 1, 1951], No. 25527/51. Class 40 (7). In an intensity-modulated cathode-ray tube display, the intensity of a displayed transient signal is increased by causing the signal to initiate a pulse of longer duration than said transient signal which reduces the scanning speed of the cathode beam and increases its intensity during the period of said pulse. As shown, the sweep voltage is generated by charging a capacitor 3 through a resistor 4, the capacitor being periodically discharged by an electronic switch 6 controlled by a pulse generator 8 actuated by a trigger pulse 9 and the sweep voltage is applied to a deflector coil 1 via a cathode follower 10, normally closed electronic switch 11 and amplifier 13. A transient signal 17 generates at 16 two pulses 14, 15 of equal duration, the positive pulse 15 being applied to the grid of the cathode-ray tube 2 and the negative pulse 14 being applied to open switch 11 for the duration of the pulse so that the amplitude of the sweep voltage developed across capacitor 12, and hence the position of the cathode-ray beam, is maintained constant for the duration of the pulse and thereafter rapidly attains the value it would have reached if switch 11 had remained closed. If it is not required to display any signals subsequent to 17 during any out sweep, the duration of pulses 14, 15 may be increased and cathode follower and capacitor 12 may be omitted, the switch 11 being then connected in series with the charging resistor 4. The invention is applicable to radar P.P.I. and type B displays; in a resolved P.P.I. system comprising two perpendicular deflector coils two scanning circuits are required, the amplitude of the charging voltages being respectively equal to sin # and cos #, where # is the instantaneous aerial bearing.
