Title: Improvements in Mechanism for Releasing Bombs or other Articles from Aircraft.
IPC: B64D1/04
Filed: 1919-01-27
Abstract: 134,446. Page, F. H., and Page, Ltd., H. Jan. 27, 1919. Dropping bombs from a height.-Relates to apparatus comprising a number of series of bombs or other objects, each series fitted with devices for releasing the bombs of the series in succession, and consists in controlling all the series from a distance by means of a single operating lever connected by a single wire to a selective apparatus comprising a number of movable members each connected to the releasing devices of a series of bombs. As shown in Fig. 9, each bomb 2 is held by a hook 29 pivoted at 30 and locked by a catch 32 with a tail 34 passing into a notch 35 of a slide 3. When the slide is moved to the left, the catch is deflected and releases the hook which allows the bomb to fall. As shown in Fig. 1, the bombs 2 are arranged in six parallel series of four, each provided with one releasing slide 3 connected by a wire 4 to the selective apparatus 6, which is in turn connected by a single wire 8 to a single operating lever 9. The selective apparatus, Figs. 2 and 3, comprises an operating slide 7 connected by the wire 8 to the operating lever, and a number of slides 11 - - 16, one for each wire 4. The operating slide 7 has a pawl 18 normally kept out of action by a fixed cam 27, and a handle 26 connected to a spring 17 which tends always to return the operating slide and with it the operating lever to their normal positions. The first stroke of the operating slide brings the pawl 18 against a tooth 19 on the first slide 11 and draws that slide to the left, where it remains held by a trigger 24, one such trigger being provided for each slide 11 - - 16; the stroke may be performed in steps to release the bombs of the series singly, instead of all in quick succession. During the last part of the stroke of the slide 11, a stud 20 thereon bears on the second slide 12 and moves it slightly to the left to bring its tooth 19 in the path of the pawl 18, so that the second stroke of the operating slide 7 will be transmitted to the second slide 12 to release the second series of bombs; and so on in succession. The slides 3 and 11 - - 16 are returned to their normal positions by springs 22, Fig. 1, when the triggers 24 are released by hand.

Title: Improvements in sound-recording apparatus
IPC: H03G3/20
Filed: 1926-01-27
Abstract: 269,978. Columbia Graphophone Co., Ltd., and Mitchell, F. A., (Columbia Phonograph Co., Inc.). Jan. 27, 1926. Magnetic instruments. - An electromagnetic sound recording device is provided with additional electromagnetic means for damping the armature carrying the recording tool when the amplitude of vibration exceeds a predetermined limit, vibration below this limit being undamped by said means, whereby sound represented by a vibration B, Fig. 7, is recorded as a vibration B<2> when the dotted line A represents the amplitude above which the vibration is to be damped. The additional means comprise separate magnets, or additional windings on the magnets influenced by the microphone, supplied with steady current regulated to furnish the desired normalizing control of the armature. Fig. 5 shows, an arrangement in which windings J, J<1> on magnets X, Y acting on an armature E carrying the stylus are influenced by currents from the microphone M after amplification and control by thermionic valves V, V<5>, V<7>, V<6>, V<8>, and additional windings K, K<1> on the magnets receive current from a battery O through an adjustable potentiometer G<1> or from a thermionic valve with grid control, to produce a steady but adjustable flux. The variation of flux due to the microphone-influenced windings is alternately added to and subtracted from the steady flux to vibrate the armature, but when such flux variation exceeds the steady flux, the polarity of the corresponding magnet is reversed and produces a damping effect at such periods, which can be predetermined by adjustment of the current through the windings K, K<1>. A further compensating effect can be produced by shunting a portion of the current from the last valves, under control of a potentiometer N<2>, through additional windings N, N<1> of the magnets. The same windings may carry both currents provided the alternating current from the microphone is communicated thereto through condensers arranged to arrest passage of the steady current. Figs. 8 and 10 show one arrangement of electromagnets X, Y secured to a head F pivoted to a supporting bracket F'. The head mav be lifted to raise the stylus S from the record Z by a hand lever W<1> on a shaft W pivoted in the bracket F<1> and carrying a cam W<2> arranged to engage a lug F<4> integral with the head F. The windings J, J<1> receive the microphone current, the windings K, K<1> receive the steady normalizing current and the windings N, N<1> when provided receive the compensating current shunted from the valve output of the microphone circuit. The magnet poles act on armatures E<1>, E<2> fixed to a non-magnetic bar E carrying the stylus S and resiliently mounted by flexible steel rods E' from a supporting plate X<5>. Adjustable screws R<1> bearing against rubber pads R provide mechanical damping means for the stylus bar.
