Patent GB-2322985-A (GB)
Title: Passive rangefinder
Inventor: FRENCH HERBERT ALAN
IPC: G01S11/02
Filed: 1988-05-03
Abstract: A passive rangefinder for determining the range to an object such as an aircraft, rocket or missile which emits electro-magnetic radiation makes use of spectral measurements over a broad band of frequencies. The rangefinder includes means 202 for forming a real inage of a field of view, spectrophotometer means 201 including an entrance aperture placed to receive at least a part of said real image, dispersion means (15, 28, 29 Fig 1 not shown) for separating radiation of different wavelengths and detector means (24) for measuring the spectrum of radiation received from distinct portions of the entrance aperture. The detector output is connected to data processing means 204 arranged to deconvolve the received spectral profile with a stored representation 205 of a range-dependent atmospheric transmission spectral profile to obtain a representation of the spectral emission profile of radiation from the object. From the emission spectral profile a characteristic temperature of emission 206 is derived and hence a Planck emission spectrum for the object. The Planck spectrum is used to determine the range from the calculated emission spectrum and the observed spectrum 205, 208. Thus by deconvolving the measured spectrum with the atmospheric transmission spectrum the range can be determined. The invention can work at any range of e.m. radiation for which suitable components are available. Advantageously the ranging is done on two different temperature portions of the same object so that different Planck profiles are used in the signal processing. The atmospheric transmission spectrum can be measured prior to operation in the prevailing conditions by use of a laser rangefinder.

Title: Fibre-reinforced elastomeric sheet
Inventor: HALL DAVID GEOFFREY
IPC: C08J5/24
Filed: 1990-12-14
Abstract: In a process for the manufacture of fibre-reinforced elastomeric sheet suitable for use as gasket material, a laminate of non-woven fibrous fabric eg. glass tissue, impregnated with a suspension of inorganic filler such as calcium carbonate in an aqueous dispersion of curable elastomer substantially free from organic elastomer-solvent (such as toluene), is cured under heat and pressure to obtain sheet of compression at least 4%, recovery at least 40% and defined stress retention. The process yields a product much less anistropic than that obtained from the well known "it" calendering process, which utilises free reinforcing fibre. The process is also advantageous in that, avoiding the use of organic solvent for the elastomer, it also avoids pollution of the environment.
