Title: Infrared simulator cathode-ray tube
Inventor: SCHOLZ DR STEFAN
IPC: H01J31/10
Filed: 1984-07-09
Abstract: An infrared simulator serves to directly transduce electron beams into IR radiation. To this purpose a modified cathode-ray tube (12) is provided with an IR transmissive window (16). Behind this window within the vacuum of the cathode-ray tube a film (14) is arranged in order to transduce the electron bombardment into IR radiation. The film 14 is of a type known for transducing visible light into IR radiation, and comprises a thin film of, e.g. plastic sheet with a thin coating of metallic blacks. The cathode-ray tube is double walled for the circulation of cooling fluid. The window 16 may be formed as a lens. The simulator is used for testing IR sensors. <IMAGE>

Title: Devices for scaring away birds or other pests or vermin
Inventor: JONES GEOFFREY RANSFORD
IPC: A01M29/16
Filed: 1984-07-18
Abstract: A scarer comprises loudspeaker means which in use produces sounds for scaring away birds and other creatures. The sounds comprise shock-sounds resembling gun-shots, explosions or the like. They may also include scare-sounds resembling the warning calls of birds or other creatures. Electrical signals fed to the loudspeaker means are derived from solid-state electronic means so that moving parts, such as are necessary for the reproduction of sound from magnetic tapes, can be avoided. The sounds are produced intermittently and are desirably arranged at random time intervals to avoid the birds or other creatures becoming accustomed to them. The scarer may be self-contained and powered by electric battery or solar cells. The volume of sound may be adjustable. The scarer may incorporate a photo-sensitive device so connected as to prevent the scarer making sounds when it is dark.

Patent GB-2172095-A (GB)
Title: Ripcord release valve
Inventor: FEIERT DIETER
IPC: F16K15/20
Filed: 1985-09-11
Abstract: A ripcord release valve allowing pressurised gas to be released from a cylinder to fill an inflatable raft for example, includes a valve body 2 having a sealing disc 16 sealing off an axial discharge passage 7 through which, when the disc 16 is pierced, gas can pass from the cylinder to flow, via a transverse passage 15, to the raft. The disc 16 can be pierced by a tappet 22 moveable longitudinally by a cam 55 formed on a ripcord disc 46 rotatable, in an axial plane of the tappet 22, about a rotational axis perpendicular to the tappet axis. The rotational mounting of the disc 46 is carried by a casing top part 3 from which the ripcord 51 extends and part 3 is freely rotatable relative to body 2 about the tappet axis. The form of the cam 55 allows a high mechanical advantage to be secured during the initial part of a pull on ripcord 51 to pierce disc 16, with a relatively rapid projection of tappet 22 through disc 16 after initial piercing of disc 16, followed in turn by withdrawal of tappet 22 from the disc under the action of a return spring 17. <IMAGE>

Title: Production of ear mouldings and other moulded articles of acrylic polymers
Inventor: CARR PETER JOSEPH
IPC: C08F20/08
Filed: 1985-10-03
Abstract: The premature polymerisation of acrylic-polymer-forming materials in the presence of a peroxide catalyst is prevented by the incorporation of a substance reacting with the peroxide to prevent its initiation of the polymerisation, particularly camphorquinone. Polymerisation of the resulting mixture can be initiated by the use of blue light or light including a substantial proportion of blue light. The mixture is particularly valuable for the production of ear mouldings and can be stored for a prolonged period in the absence of blue light.
