Patent GB-2180361-A (GB)
Title: Thermal imaging device
Inventor: HILSUM CYRIL
IPC: G02F1/133
Filed: 1986-08-07
Abstract: A thermal imaging device uses a compensated cholesteric liquid crystal mixture (1) as its thermo-optic conversion element. The mixture is obtained by mixing two cholesteric liquid crystals, one with a left- handed twist, e.g. cholesteryl myristate, and the other with a right-handed twist, e.g. cholesteryl chloride. The twists cancel at a compensation temperature (TN) the mixture thus having infinite twist at this temperature. The device is designed to operate with the mixture (1) held in the region of the compensation temperature (TN). Light from source (19) passes through a polariser (23) and is reflected by a dichroic mirror (17) onto the liquid crystal mixture (1). Infra-red radiation from a field of view is focussed by lens (25) onto the mixture thereby rotating the direction of polarisation of the light from source (19) by an amount dependent on the intensity of infra-red radiation. This is sensed using an analyser (31) and detector (29). <IMAGE>

Title: Firing of well perforation guns
Inventor: GEORGE FLINT RAYMOND
IPC: E21B43/1185
Filed: 1987-01-21
Abstract: A method and apparatus for actuating a perforating gun by pressure includes a pressure actuated gun firing head (60) disposed on the perforating gun for detonating the shaped charges of the gun to complete an underwater well. The gun is attached (at 88) to a pipe string and located downhole adjacent the formation to be perforated. The pressure actuated firing head includes a housing (62) with a plug (160) and piston (120). The piston has a firing pin (140) adapted for engagement with the initiator (90) of a perforating gun upon reciprocation within the housing. initially, the piston is pressure balanced until the time of actuation. The plug is responsive to fluid pressure of a predetermined magnitude at the time of the actuation of the gun firing head. Upon effecting pressure on the plug, the plug unbalances the piston causing the piston to move downwardly. Upon such movement of the piston, the firing pin engages the initiator to detonate the shaped charges of the perforating gun. Pressure may be effected on the firing head through the pipe string, or the annulus around the pipe string, or both. The firing head includes a plurality of passageways, as well as the plug and piston, arranged in a manner whereby should leakage of well fluids into the firing head inadvertently occur, the apparatus is rendered inoperative and therefore the firing head cannot inadvertently be fired due to the occurrence of unforeseen intervening circumstances. <IMAGE>

Abstract: An interrogator having a 100KHz oscillator 10 supplying a buffer amplifier 12 and thence a modulator 14 to produce a modulated signal of short duration pulses, the modulator 14 being controlled by a modulating pulse of 1 KHz obtained from the oscillator 10 by the use of two divide- by-ten counters 22, 24 and a pulse shaper 26. The signal from the modulator 14 is fed to a power amplifier 16 and thence to a transformers primary coil 20. The transformers secondary coil 28 has a ferrite core thus a voltage will be induced in said secondary coil 28 by the primary coil 20. This voltage is amplified 30 and then supplied to a detector 32. If an intervening transponder coil is short circuited the impedance will be altered and there will be a flux change in the interrogator's primary coil 20 causing a change in the voltage induced in the secondary coil 28. This voltage change can be detected by the detector 32 and interpreted as a binary code data transmission. <IMAGE>
