Double diaphragm, double diaphragm

    We will award (at our own expense), half a dozen (virtual) sticky buns to the first person who tells us what exactly the Type ZW1 does and what is the application that the Commissioners of Irish Lights may have put it to?
  • Suck Diesel said:
    “AI Overview
    The images depict a double diaphragm submarine emitter, labeled as Type ZW1, with a sound output of 250 watts. Figure 31 shows a diagram of the emitter, highlighting its internal components marked A and B. Figure 32 is a photograph of the emitter itself.”
  • Suck Diesel said:
    Wild guess, is this attached to a ship to identify itself to a submarine that it caries medical or other non hostile supplies?
  • National Library of Ireland on The Commons said:
    Suck Diesel Plausible, but I would need some evidence.
  • Suck Diesel said:
    Of course, ‘submarine’ just means underwater, not necessarily a U-boat.
    I don’t think that Irish Lights has anything to do with U-boats so this device is used to emit a sound underwater, but purpose unknown

    A close run thing witnessed from the rock and the SS Irene. Reported widely, this is from the Sheffield Evening Telegraph on Saturday 13 July 1901
    THE FASTNET ROCK. PASSENGER STEAMER'S NARROW ESCAPE Crookhaven correspondent telegraphs:—At about three yesterday a large passenger steamer, westward bound, had a miraculous escape from total wreck on the Fastnet, and was saved only through the prompt and decisive action on board, the lifting of the fog at tho nick of time, and by the praiseworthy conduct the light keepers and men the Fastnet rock. The steamer Irene, Captain Fleming, of the Irish Lights, was close the at the time, engaged in connection with the building of the new lighthouse, when those on board were horrified to see a large four-masted passenger steamer coming from the east full on the little Fastnet. The light keepers discharged the alarm gun quickly as possible twice in quick succession, and signalled urgent danger. Before the vessel could slowed or reversed she had, however, apparently touched the rock, she was seen to list to starboard and then to port, and all those who were looking feared serious disaster. The rock referred to is about 400 yards east-south-east of the Fastnet rock, and low tide has only about two fathoms of water over it. No serious damage happened, as she proceeded on her voyage apparently uninjured. It had also transpired that a week before a similar accident nearly occurred to a larger passenger steamer homeward bound. About 11 o'clock she touched the Fastnet on the west side, and a disaster was averted only by the discharge of the Fastnet alarm gun.

    Wrecked at Grimness in 1969 in the Orkneys. The Longhope lifeboat had launched to assist and overturned with the loss of 8 crew in 60 foot waves. www.scotsman.com/arts-and-culture/orkney-lifeboat-tragedy... And some photos of the wreck. photos.orkneycommunities.co.uk/search.asp
