Patent GB-2079932-A (GB)
Title: Opto-electronic microphone
IPC: G02B26/02
Filed: 1980-07-08
Abstract: An optical microphone uses optical gratings 2, 3 mounted adjacent and parallel to each other, with one grating coupled to the centre of diaphragm 1 which can be conical or planar. Light source 4, e.g. a light- emitting diode is on one side of the gratings, and light detector 5, e.g. a photo-diode is on the other. As the diaphragm vibrates in response to incident sound waves, the relative movement of the gratings modulates the light beam so that the photodiode gives a modulated current output, which can be amplified. The gratings can be so set that there is a small angle between the lines on them, to improve sensitivity, and the angle may be adjustable. The invention is also applicable to acousto-optical transducers such as hydrophones, and a seabed hydrophone can be coupled to a shore station via optical fibre cable for supply of light from the source and reception of modulated light. <IMAGE>

Title: Bottom fuse particularly for a gun grenade
IPC: F42C15/24
Filed: 1981-02-27
Abstract: The fuse provides safety against striking objects before the effluxion of the predetermined arming period and comprises a fixed striker 17, a slidable detonator 14, a locking ball 28 and two inertia sleeves 21, 22 separated by a spring 25.
