Title: Magnetostrictive vibratory systems and apparatus for use in subaqueous and other signalling systems
IPC: B06B1/08
Filed: 1928-01-03
Abstract: 314,891. Pierce, G. W. Jan. 3, 1928. Divided on 283,116, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 4, 1928. Subaqueous audible signals.-Magnetostrictive vibrators of the kind described in Specification 313,031, [Class 38 (iv), Electric supply and transmission systems &c.], comprise a magnetic core surrounded by a coil carrying alternating or oscillatory current, and the free frequency of mechanical vibration of the cone is substantially the same as the frequency of the associated circuit, so that the core vibrations set up by magnetostriction are accentuated by mechanical resonance. In the present invention, the vibrator is employed for transmission or reception in subaqueous and other sound-signalling or ultra-audible signalling systems. For use in water or other dense medium, several cores 2 are arranged in a ring with their ends attached to flat pieces 58, Fig. 1. A rubber baud 60 may enclose the apparatus. In another form, the cores carry cross-heads 62, Fig. 3, and are arranged in parallel rows. The coils 22 are connected in series or in parallel and the current preferably passes in opposite directions in adjacent coils. A single core 2 may extend across a ship and may be attached to the opposite sides, which thus act as sound radiators. For producing sound or speech vibrations in air, the core 2, Fig. 6, may be attached to wing members 68, 70 near their supporting base 72. The wings damp the resonance of the cone. The currents for energizing a signal transmitter may be generated by a valve, and the current developed in a signal receiver may be amplified by valves, and made audible in a telephone by heterodyne or otherwise.

Abstract: 484,540. Automatic exchange switches. MIX & GENEST AKT.-GES. June 11, 1937, No. 16273. Convention date, June 19, 1936. [Class 40 (iv)] A unitary wiper-choosing rotary switch comprises an assembly 4 of a number of wiper sets and a further wiper assembly 3 for selecting a set, both mounted on the same axle and stepped independently with the speech wipers out of contact with the bank, the wipers being subsequently brought into engagement with the bank. The wipers of the sets, other than the speech wipers, are collected together at the driving (right-hand) end of the assembly to decrease the torsional stresses due to these wipers which rotate in engagement with the bank. The two assemblies are stepped by magnets 6 and 5 respectively and both wiper assemblies are moved axially to the right to make contact by a magnet 7, the armature 8 of which engages a disc on assembly 3, the two assemblies being in axial abutment. The assemblies are held in the contacting position by a pawl 10 which drops into a notch in assembly 3, mechanically locks the armature of magnet 7 in a manner not shown, and opens a contact 27 in the circuit of this magnet. Release is effected by operating magnet 5, the armature of which releases pawl 10 so that the assemblies move back axially under the natural spring action of the wipers, the assemblies being rotarily restored in any suitable manner. The wipers of each assembly are moulded into a tubular insulating member internally threaded to receive a ratchet wheel at one end and a nut at the other end for securing a position indicating disc, the wheel and nut being bored to serve as bearings on the switch axle. The axle, assemblies and driving mechanism are mounted in a frame 1 carrying a terminal strip 22 for the leads to the magnets &c. When the switch mechanism is assembled on the bank, strip 22 engages feed springs 23 which together with wiper feed springs 24 and the ordinary contact springs are formed into a unitary bank by a moulding operation. The ends 25 of the wiper feed springs are shaped to facilitate engagement with the wipers.
