Title: Improvements in or relating to means for electrically producing sounds by acoustic warning or signalling apparatus
IPC: G08B3/10
Filed: 1928-09-14
Abstract: 297,092. Blondel, A. Sept. 14, 1927, [Convention date]. Audible signalling systems.-An electromagnetically operated sound producer is operated from a power supply of commercial frequency through the intermediary of a frequency changer. As shown in Fig. 1, the vibrator V of the sound producer P is operated by an electromagnet E which is supplied through a frequency changing transformer T<1> from a source A of low frequency current. The secondary circuit is tuned to an harmonic of the supply frequency by a condenser Cm and the corresponding high frequency is produced by reason of the saturated condition of the transformer core. An inductive coil L prevents the higher frequency current from passing to the supply source. In a modification (Fig. 2, not shown) the transformer T<1> is replaced by an auto-transformer and in a further arrangement (Fig. 3, not shown) the electromagnet E performs the dual function of operating unit for the sound producer and raising the frequency. A battery H may be provided to saturate the core of the frequency changer or polarize the electromagnet E or perform both functions simultaneously. If desired the frequency changer may be supplied through a transformer T<2> which is shunted by condensers C<1>, C<2>. Reference has been directed by the Comptroller to Specification 178,235, [Class 13, Bells &c.].

Filed: 1928-09-19
Abstract: 297,429. Messier, G. L. R. J. Sept. 21, 1927, [Convention date]. Wheel brakes, applications of.-Aeroplanes are fitted with wheel brakes which can be applied by the pilot to the landing wheels separately or simultaneously only when there is a predetermined pressure on the tail skid, the skid either acting to take up slack in the pilot's brake transmission or effecting the application of the brakes with greater or lesser intensity according to the position of the pilot's control, no other power means being employed. A dashpot device may delay the application of the brakes while permitting instant release. Hydraulic transmission may be employed. In its simplest form a cable 8 connected to the skid 9 moves a pulley 2 to take up the slack in a cable 4 connecting the brake to the pilot's control. The cable 8 may pass through a cylinder containing oil and be connected to a piston having a leak port and a one-way valve to ensure gradual application of the brakes while permitting a quick release. Fig. 3 shows a connection 15 from the skid connected to a block 17 in a slotted lever 16 on the brake shaft 20. The position of the block in the slotted lever is controlled bv the pilot through a connection 19. Both the pilot's control and the skid may actuate pumps delivering fluid to cylinders acting upon the block 17. Fig. 4 shows a hydraulic transmission applied to the form in which the pilot's control is rendered effective or ineffective by the skid. The pilot's control delivers fluid to a cylinder 24 to actuate the brake lever, the cylinder 24 being carried on a piston 21 which is raised and lowered by fluid from a pipe 23 as the skid rises and falls. A valved diaphragm may be inserted in the pipe 23 to ensure gradual application of the brakes.
