Title: High sensitivity accelerometer for crossed dipoles acoustic sensors
Inventor: FRANKLIN J BARRIE
IPC: B06B1/06
Filed: 1986-12-15
Granted: 1992-04-28
Abstract: ABSTRACT      An  accelerometer  for  underwater  acoustic  sensors  includes a pair of cylindrical piezoelectric crystals configured in a cantilever mode  and having  attached  thereto  an  electrode  segmented  into  four equal  quadrants.   In response  to  translational motion perpendicular to the axes of the piezoelectric crystals, orthogonal voltage signals are  generated,  from which  the  crossed  dipole  directivity  patterns can be obtained.  The symmetric use of two such piezoelectric crystals enables  spurious  responses,  to  rotational  motion  about  an  axis perpendicular  to  the  central  axis  of  a  cylindrical  container  for the crystals, to be avoided.

Abstract: FIBER OPTIC IMAGING SYSTEM FOR ON-LINE MONITORING            Abstract of the Disclosure A target is viewed by means of a coherent fiber optic bundle comprising a two dimensional array of fibers.  A one dimensional linear light detector array, fixed relative to the coherent fiber optic bundle, receives an image of the target and detects light through only a slice of the image to provide dimensional information with respect to the edges of the target.  A polyfurcated bundle may view different linear dimensions of the target and allow for the use of the single linear array to detect the multiple dimensions.  Electronics provide for detection of target edges by means of a curve fitting technique, computation of dimensions and control of light source intensity and exposure time. Illumination is by a noncoherent light source and a collimator positioned behind the target or by a fiber optic bundle and a light guide plate positioned to illuminate the target from the front. An air purge of the distal optics is provided from a frustoconical annulus formed between two members and from pressurized gas introduced between the annulus and the optics.

Inventor: COCITO GIUSEPPE
IPC: C03B37/014
Filed: 1987-04-03
Granted: 1992-01-21
Abstract: ABSTRACT            Optical fibre preforms for drawing in fibres for use in the mid infrared spectral range are formed by vapourizing halides under the influence of heat and reduced pressure and directing them towards the cooled internal wall of a glass tube which is translated, and also rotated if circumferentially uniform disposition is required, so as to form a preform.  The preform  so formed may be collap-sed, and if the tube is of oxide rather than halide glass, its material is stripped from the preform.

Abstract: IMPROVED ATMOSPHERIC GAS BURNER                 ABSTRACT OF THE DISCLOSURE           An improved burner for heating water in a hot water system is provided.  This burner includes an inlet tube having flared ends and a constricted middle portion to provide an increased amount of air into the barrier. The burner also includes a barrel which communicates with the inlet tube to receive fuel gas and air from it.  It vents this air and fuel gas mixture through a large number of ports formed through its sidewalls and arranged in a predetermined pattern to produce a continuous combustion layer when the user ignites the venting mixture.  These ports have a width substantially smaller than their length and they produce small, nonluminous, bluish flames which form the combustion layer.  This combustion layer burns hot to raise the temperature of the barrel segments surrounding the ports to a level at which the segments glow red and emit infrared heat.

Abstract: A device for forming a solder connection between a plurality of elongate bodies comprises a dimensionally recoverable  article,  e.g.  a  heat-shrinkable  sleeve, into which the bodies can be inserted, and a solder insert.  The solder insert comprises two portions, one formed from a relatively low melting point solder for forming  a  solder  joint  between  the bodies,  and the other  portion  being  formed  from  a  relatively  high melting point solder.   When the device is heated the relatively  high  melting  point  solder  will  not melt until  the  low melting  point  solder  has  melted  and flowed, and therefore provides a means for indicating that the correct temperature has been reached.

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 image of a field of view, spectrophotometer means 201 including an entrance aperture 27 placed to receive at least a part of said real image. dispersion means (15, 28, 29) for separating radiation of different wavelengths and detector means 24 for measuring the spectrum of radiation received frown 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.
