Patent GB-2137031-A (GB)
Title: Fluid Conductivity Sensing Device and Circuit
Inventor: MILLER FRANCIS M
IPC: G01N27/06
Filed: 1984-01-31
Abstract: The circuit can be used to detonate an electro-explosive device 86 for operating a release mechanism for uncoupling a parachute canopy from its load upon landing in water. An SCR 60 is turned on to charge an ignition capacitor 64 when a conductivity sensing circuit 70, 72, 74, 78 senses the conductivity between electrodes 24, 34 and the rate of charge of conductivity to be above certain levels. A voltage independent portion of an operating network turns on an SCR 90 after a time delay from the start of charging of capacitor 64, which delay is independent of the rate of voltage rise on capacitor 64. SCR 90 discharges the capacitor 64 through the device 86 to activate it. The operating network also has a voltage dependent portion which, when a voltage of predetermined magnitude is developed on the conductivity sensing circuit in response to fluid not having the predetermined condition of conductivity, timer on SCR 90 to define the discharge path through device 86 when the energy in capacitor 64 is insufficient to detonate the electro explosive device. A regulated current source 78 is connected in relation to the conductivity sensing circuit and to the electrodes 24, 34 thereof in a manner placing the circuit voltage across the electrodes when the conductivity is below a predetermined magnitude so that the sensing circuit does not respond thereto and placing the circuit voltage across the sensing circuit when the conductivity is greater than a predetermined magnitude. The apparatus is operated from a battery, and the electrodes are of dissimilar metals so selected and connected relative to the polarity portions of the circuit to maximize utilization of the battery output voltage. <IMAGE>

Patent GB-2180940-A (GB)
Title: Detecting damage in composite materials
Inventor: SYED CHARLES ABRAHAM WALTER KA
IPC: G01N27/20
Filed: 1985-09-28
Abstract: The condition of a composite material under stress is monitored by incorporating an electrically conductive fibre in the material and observing the electrical resistance of the fibre. When the material reaches a condition where it suffers permanent damage, the fibre also suffers permanent damage and as a result the electrical resistance of the fibre increases sharply. This will normally happen before there is any visible evidence of damage. The change in resistance can easily be detected using simple equipment. <IMAGE>

Title: Apparatus for indicating and/or measuring extremely small amounts of flowing media
Inventor: CSANAK TIBOR
IPC: G01M3/26
Filed: 1986-04-14
Abstract: Flow is indicated by movement of a droplet (8) of liquid in a capillary tube 3 which is at an angle of inclination  alpha  to the horizontal such that the component of the gravitational force acting along the axis of the tube just balances the capillary forces and/or surface tension effects exerted on the droplet. This reduces measurement time and increases accuracy. The tube may be rotated to form the droplet from liquid in the top header and then back to the angle  alpha . The apparatus may be manually operable and constructed as a hand gun or it may be an automated measuring instrument associated with a production line of pressure vessels, e.g. a gas flask filling or refilling line where it is used to detect leaks. <IMAGE>
Patent GB-2179422-A (GB)
Title: Gas spring
Inventor: ROHRMOSER WERNER
IPC: H01H3/16
Filed: 1986-08-05
Abstract: A gas spring comprises a cylinder 2 and a piston rod 3, and defines an electrically conductive path included in an electrical circuit. A switch in unit the gas spring selectively opens and closes the conductive path according to the direction of relative movement of the piston rod and cylinder. The switch unit comprises a contact piece 9 which is in frictional and electrically conductive engagement with the internal sliding surface 2a of the cylinder 2. This contact piece 9 is axially movable with respect to the piston rod 3 between two terminal positions. In a first terminal position during outward movement of the rod 3 (as shown) the contact piece 9 closes the electrically conductive path by abutting the surface 11 of a conductive piston disc 7. In a second terminal position during inward movement of the rod 3, the contact piece 9 abuts the surface 12 of an insulating piston disc 8 and thus opens the electrically conductive path. The contact piece may be in frictional engagement with the rod as at 25 rather than the cylinder, the contact piece then engaging either insulating member 26 or projection 27. The unit is useful for switching an anti-theft device for a boot lid. <IMAGE>
