Filed: 1938-10-21
Abstract: 517,006. Delivering fuel to furnaces. McKEAN, J. G. Oct. 21, 1938, No. 30475. [Class 78 (i)] In the mechanical stoking of furnaces where the space between the front of the furnace and the wall of the boiler-house is insufficient to house the usual form of stoker employing a feed screw and also to provide space for ready access to the furnace for cleaning and repair, a shortened form of stoker is used with special driving means for the feed screw. In this construction the driving-motor 14 and change-speed gear 13 are located in the space between the main stoker structure and the furnace and transmit'power to a longitudinal shaft 9 arranged directly under and parallel to the feed'screw 4 and geared to the latter at 11. A platform 8 is fitted in the space 5 over the motor and the feed screw to give ready access to the furnace 2. The fuel is delivered by the screw from the bunker l.to the furnace. In a modification, the driving- shaft 9 is also formed as a screw driven in either the same or the opposite direction to the screw 4. This screw 9 is intended to pile up the fuel against the wall 1<1> of the bunker to feed the main screw 4.

In an arrangement for measuring the magnetic leakage flux from a magnetic core 1 having A.C. windings; a Hall plate, having a pair of current input electrodes 7, 8, and a pair of Hall voltage output electrodes 3, 4, is positioned in the leakage flux; the flux lines of force extending at right angles both to the direction of current flow between electrodes 7, 8 and also to the line joining the electrodes 3, 4; an input current proportional to the flux leakage is applied to electrodes 7, 8; and the component of the Hall voltage at the second harmonic of the A.C. supply to the core windings is measured. Electrodes 7, 8, on faces 9, 10 of the Hall plate, are connected to the ends of a loop embracing the transformer core 1, whereby an E.M.F. is applied across faces 9, 10 which is proportional to the varying core flux; faces 5, 6 of the Hall plate are connected by electrodes 3, 4 to an amplifier 11 which selectively amplifies the Hall voltage component of the second harmonic of the A.C. supply to the core windings; this component being proportional to the product of the magnetic leakage field through the Hall plate and the current flowing between faces 9 and 10 due to the applied E.M.F. In a second embodiment, Fig. 2 (not shown), the input current applied to electrodes 7, 8 is provided by the output of an amplifier, the input to which is obtained from two antennae having their ends positioned adjacent the faces 9, 10 of the Hall plate.

Title: Apparatus for lighting the landing place from aerial crafts
IPC: F42B10/56
Filed: 1925-12-07
Abstract: 260,933. Soc. Anon. pour l'Exploitation des Brevets K³nzer. Nov. 4, 1925, [Convention date]. Parachutes. - In a parachute flare provided with timing means for predetermining the movement of the firing of the lighting charge with respect to the moment of the unfolding of the parachute, the parachute is ejected by a spring- urged piston which is released by clockwork mechanism. The arrangement described comprises an outer shell 81 divided into three chambers by partitions 82 83. 84, the upper and middle chambers housing the parachute 184 and the clockwork timing apparatus, respectively, and the lower chamber 100 containing a fireproof composition for insulating the device from a slotted nose 101 containing the lighting charge. The parachute is attached by ropes 85 to the rim of the shell 81 and packed in a cylinder 183 above a piston 87 urged upwardly by a helical spring 86 but normally held down by a hooked rod 187 on the piston. When the pistcn is forced down, the nose 88 on the rod 187 is thrust through an opening 89 and on being given a turn engages the under side of the partition 82. When the device is not in use, the parachute is held in by two hinged arms 120. The lighting charge communicates through a canal 104 in the chamber 100 with a tube 103 provided with a cartridge primer 105 adapted to be fired by a hammer 106 which is cocked by a trigger 107 and released by a pivoted detent 108 moved by an arm 112 connected to the driving spindle cf the clockwork mechanism. The tube 103 is accessible through a door 114 in the shell 81 and may be moved along a slide 113 to close the canal 104 and to prevent accidental firing by the hammer 106. A cudved extension 94 on the driving spindle is also arranged to engage the nose 88 and release the piston 87 to eject the parachute, simultaneously with, or a predetermined time before, the hammer 106 is released to fire the charge. The extent to which the clockwork winding handle 96 is turned is indicated on a scale on a plate 200 and determines the time which will expire between the release of the device from the aircraft and the ejection of the parachute. A brake 198 on the clockwork goevrnor 92 is released at the moment the device is dropped. The charge may be fired by an electric battery. According to another modification the nose 101 may be released from the shell 81 at the moment of firing. A modification is referred to in the Specification as open to inspection under Sect. 91 (3) (a) in which the timing is effected by an air-draft propeller on the device which rotates the disc carrying the cartridge priming and fires the charge after the apparatus has fallen a certain distance. This subject-matter does not appear in the Specification as accepted.
