Title: Improvements in or relating to mechanism for operating the hood of the pilot's cabinof aircraft
IPC: B64C1/14
Filed: 1943-11-29
Abstract: 569,330. Fastenings. HAWKER AIRCRAFT, Ltd., HOLLYHOCK, W. S., WHALE, S. H., and KERR, J. P. Nov. 29, 1943, No. 19933. [Class 44] [Also in Group XXXIII] An aircraft cockpit hood with integral tail piece is slidably mounted on three rails, one at each side and one at the rear of the cockpit, the rails being detachably mounted in housings on the fuselage to permit of jettisoning of the hood in an emergency, means also being provided to assist the pilot in moving the hood rearwardly against aero-dynamic forces in flight. The hood 19 is provided with trolleys 20 movable along slide rails 5, 6, the bases of which are provided with lugs 8 engaging in recesses 7 in the bases of the fuselage housings to retain the rails in position. The forward ends of the slide rails are also provided with bolts 10 engaging in sockets formed in the fixed portion of the structure. Movement of the rails is normally prevented by means of locking pins 12, Fig. 10, attached to bell crank levers 28 connected by cables 47 to the hood release mechanism. This latter comprises a tube 30, Figs. 2 and 11, housing a spring 31 compressed by a bolt 33 passing through a rectangular nut 34 engaging a plug 36 at the end of the tube and a lever 37 which may be actuated by the pilot through a cable. Rotation of this lever turns the nut 34 into a position in which it can pass through the plug under the influence of the spring, which actuates the cables 47 to rotate the bell cranks 28 which first withdraw the locking pins 12 and then bear against lugs 26 on the under sides of the slide rails to disengage the lugs 8 from the recesses 7. The release spring 31 may operate under tension, or compressed fluid may be used to actuate the release mechanism. One or more panels 16 at the side of the cockpit may also be freed by operation of the hood release mechanism. The hood is moved along the slide rails by means of a rack and pinion 49, 50, Fig. 12, on each side of the cockpit actuated by chain and sprocket gearing, the pinions 50 being keyed to a torsion shaft 51, Fig. 12, carrying a spring 56, the ends of which are secured to collars 57, 58, the former being keyed to the shaft 51 and the latter freely rotatable thereon. A ratchet wheel 59 is secured to the collar 58, and is engagable by a pawl 64. When the pawl and ratchet are in engagement, forward closing movement of the hood tensions the spring 56, the energy stored in which assists the pilot in opening the hood during flight. The spring is rendered inoperative by disengagement of the pawl, enabling the hood to be moved freely when the aircraft is parked on the ground.

Title: Improvements in electric discharge tubes
IPC: H01J19/68
Filed: 1920-07-09
Abstract: 148,184. Kossel, W. March 1, 1917, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes. - In discharge apparatus, such as an amplifier or Rontgen-ray tube, the emission of electrons from an auxiliary cathode is produced bv the impact thereon of canal rays set up by the discharge in the tube between an anode and the main cathode, and the electrons are controlled by an electrostatic or electro-magnetic field. As shown in Fig. 7, the positive ions produced by the discharge between the anode A and the main cathode AK pass through the cathode as canal rays and impinge on the auxiliary cathode C, the discharge of electrons from which is controlled bv the difference of potential between the cathodes C, AK supplied by a battery B and a transformer I in the circuit containing current to be amplified &c. A telephone receiver T is coupled through a transformer II with the anode circuit. The auxiliary cathode C may be mounted behind, and insulated from an axial extension of the cathode AK, in which the canal rays are concentrated, or, as shown in Fig. 2, it may be mounted in a part AK<1> of larger diameter, which is screened from the canal rays by the axial extension D, the part AK<1> serving to set up a controlling electric field. The cathode C is preferably of material electropositive to the material of the cathode AK. In the arrangement shown in Fig. 3, which may be used in a tube containing gas at a pressure of a tenth of a millimetre of mercury, the positive ions are concentrated by means of a magnetic field. For this purpose the main cathode AK consists of two hollow cylinders of soft-iron forming the poles of a permanent magnet mounted inside or outside the tube, the cylinders being separated by a circular gap S surrounded by an annular anode A. The electron-emitting cathode C is in the form of a cylindrical rod preferably insulated from the cylinders. An electric field is produced between the cathodes AK, C. The parts X of the cylinders adjoining the gap may be of non-magnetic material and may be extended inwards as shown to concentrate the electrode field towards the cathode C. Two additional cathodes, protected from the canal rays, may be mounted around the cathode C and inside the cathodes AK. The electro-magnetic controlling field may be produced by a winding around the tube. The field of the magnet may be controlled by means of an adjustable shunt. According to the Specification as open to inspection under Sect. 91 (3) (a), the cathode C may be of the incandescent type, and the cathode AK, Fig. 7, has a number of perforations. This subject-matter does not appear in the Specification as accepted.

Abstract: 457,176. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. July 20, 1936, No. 20096. Convention date, Aug. 3, 1935. [Class 40 (v)] Relates to methods of defining a narrow sector, such as that between the two guiding lines AB, Fig. 1, formed by the overlapping beams I, II, III. According to the invention the distinction between the signals received inside the sector, and outside it, is made more marked by producing each guiding-line L1, L2, Fig. 4, from pairs of overlapping beams I, II and III, IV, each pair being radiated on a different wavelength, or in sequence, or with different polarization, and being differently modulated. For instance the modulation notes a, b, c, d, may be such that a. c and b, d give a discordant combination outside the sector L1, L2, whilst band c give a consonant response inside it. On the wavelengths of the two pairs of overlapping beams may be so far apart that each guiding-line is ascertained on a different receiver. The system is stated to prevent errors due to re-radiation effects.

Abstract: 1472380 Circuit breaker overload adjustment WESTINGHOUSE ELECTRIC CORP 13 May 1975 [15 May 1974] 20104/75 Heading H1N A multi-pole circuit breaker having a thermal overload tripping element 89 associated with each pole and a common release mechanism comprising toggle linkage 39, 41, over-centre spring 45 and releasable trip member 43, is provided with means for common adjustment of overload trip ratings comprising a trip bar 87 journalled at 95 in the insulating barriers 15 between each pole unit and carrying fingers 97 associated with each of the thermal trips 89. The trip bar has a cross-arm 101 carrying a screw-adjusted latch 103 which latches a trigger 57 to retain the releasable trip member 43 against clockwise rotation under the action of spring 45. Clockwise movement of screw 99 due to heating of the bimetallic thermal trip 89 results in counter-clockwise movement of trip bar 101 until the end-face 105 of latch 103 moves past the end of the trigger 57 to release it and thus trip the breaker. The setting of screw 93 predetermines the amount of movement of the overload trip required to release the trigger and thus provides a common, simultaneous rating adjustment of up to 20% on all thermal overload trips. An electromagnetic trip 75, 115 acting upon an armature 109 linked through a member 113 to the end of the trip bar remote from the latch is also provided for each pole unit.

Title: Improvements in television systems
IPC: H01J31/30
Filed: 1947-07-25
Abstract: 665,737. Cathode-ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd. July 25,  1947 [Jully 25, 1946], No. 20112/47. Class 39 (i). [Also in Group XL (b)] The photo-sensitive or electrosensitive mosaic of a pick-up tube has its charge reduced to datum level by means of an auxiliary electron stream comprising fast electrons of high voltage, e.g. a few thousand volts, such that the coefficient of secondary emission of the sensitive plate is lower than unity, i.e. at a working point which is the second intersection of the secondary emission characteristic. The auxiliary cathode is either thermionic with a control grid or Wehnelt cylinder, photo-sensitive or secondary emitting. The tube 1contains a mosaic 2 comprising an insulating sheet with a signal plate backing upon which is projected an optical image of an object S during intervals permitted by the shutter 9. The charge image formed on the mosaic by photo-emission is scanned by the gun 3. the wall coating anode 4 during the open shutter period receiving a positive pulse from terminal 23 biased by diode 25 and creating an accelerating field for photo-electrons from 2. In the period just, prior to the opening of the shutter 9, the grid 11 is positively pulsed from terminal 17 to permit an electron stream from thermionic cathode 10 to flow to the mosaic and neutralize the charge image left from the previous scan. The potentiometer 12-14 and biasing diode 16 also control the electron stream. The signal plate of the mosaic is connected to an amplifier 20 to which is applied a blocking potential outside the period of scanning by the electron gun 3, the latter being similarly blocked during the illuminating and flooding periods. The subject, which may be a film or a scene, is illuminated bv intense flashes of light which are so rapidly periodic as to allow some flashes to correspond with the opening of the shutter 9 and yet avoid perceptible flicker. A modification, Fig. 3 (not shown), comprises an image-type tube wherein the optical image falls on a photo-cathode and the electron image is accelerated on to the mosaic. In this form the thermionic auxiliary cathode may be omitted and the flooding electronic stream produced by the photocathode using the same or a different shutter in flooding with light and changing and controlling the voltage applied to the photo-cathode to give the fast electrons. In other modifications, both the shutter 9 and the grid 11 may be omitted, their control being effected by suitable potentials applied synchronously to the photocathode and the thermionic cathode, respectively.
