Title: Autofocus for minimum entropy through multi-dimensional optimisation
Inventor: CHO KWANG M
IPC: G01S13/90
Filed: 2009-06-08
Abstract: An arrangement is provided for focusing an image using data generated by a synthetic aperture radar system on an aircraft. Optimisation 702 is performed to identify an array of coefficients (624, fig.6) for a polynomial representing a phase correction in a manner that minimises an entropy value (622, fig.6) generated by an entropy calculation for the image. The array of coefficients is applied 704 to the polynomial to obtain a desired phase correction (514, fig.5 and 606, fig.6). A phase error in the image (518, fig.5) is corrected 706 using the desired phase correction to focus the image. The optimisation may use a Broyden-Fletcher-Goldfarb-Shanno method. The polynomial may be a Legendre polynomial.

Title: Improvements in or relating to rubber conversion products and methods of making the same
IPC: C08C19/00
Filed: 1937-04-12
Abstract: Rubber conversion products suitable for use as adhesives are obtained by mixing rubber with a solid sulphate or acid sulphate and with one or more of phosphoric acid, phosphoric anhydride, acetic acid, and acetic anhydride, forming the mix into sheets preferably about 1/4 " thick and heating, preferably at 100-155 DEG  C. and in the absence of oxygen.  The sulphate may be aluminium sulphate or an alum or a mixture of normal and acid aluminium sulphates.  If the sulphate does not contain water of crystallization a small quantity of water should be added to the mix.  The reaction products may be homogenized by milling and during milling they may be washed with water, a solution of an alkali, e.g. caustic soda, and/or a solution of an acid, e.g. hydrochloric acid; it is stated that the washing treatments and their order effect the properties of the resulting rubber derivative.  The rubber derivatives may be used for bonding rubber to metal either in the form of a sheet or as a solution in the usual rubber solvents such as benzene or carbon tetrachloride. Specification 459,435 is referred to.  According to the Specification as open to inspection under Sect. 91, other weak acids, e.g. propionic acid, may be used in addition to phosphoric and acetic acids.  This subject-matter does not appear in the Specification as accepted.

Abstract: 632,074. Coating webs ; coated paper. COPEMAN LABORATORIES CO., and JENNINGS, H. Y. Aug. 18, 1941, No. 10466. [Class 140] An aqueous dispersion 13 comprising natural and/or synthetic rubber is applied as a coating to a moving sheet of material 10, e.g. paper by a roller 11 which dips in the dispersion and rotates in a direction opposite to that in which the sheet moves. If desired the roller may rotate at a higher speed than the speed of movement of the sheet material. After application of the coating the sheet material may be dried and the coating partially cured by passing the sheet material adjacent a heating element 16, over a heated drum 17 with coated surface exposed, and the sheet then wound on roll 20 with coated side innermost after passing under guide rolls 18 and 19. The direction of travel of the coated sheet material prior to the drying step may after leaving the coating roller be changed abruptly, for example, as shown through a right-angle. The coating, if desired, may be stripped from the sheet material. The products are suitable for use as wrapping materials. Specification 632,141 is referred to.

Title: An improved homogenizing device
IPC: B01F9/00
Filed: 1951-05-04
Abstract: In an homogenizing device comprising a hollow rotor having an inlet for the liquid to be treated, means for rotating said liquid so that it forms an annulus in the rotor and a paring member extending into said liquid, an homogenizer is disposed in the discharge channel of the paring member to receive liquid pared from the rotor.  Liquid to be treated is fed through a pipe 1, Fig. 1, to a rotatable housing 60 and conducted by channels 67 to a paring disc comprising members 37, 38 having overlapping p  flanges 40, 39 respectively and streamline inlet nipples or pins 41.  Each nipple has a cyclone chamber 42 together with a tangential inlet and an outlet 43 therefor.  The outlet 43 communicates with a whirl chamber 44 from which the liquid is discharged to a chamber 46.  In a modification the paring member comprises a disc having one or more segments attached thereto. Each segment comprises a cyclone chamber communicating with a radial bore constituting the whirl chamber.  In a second modification the common axis of the cyclone and whirl chambers is parallel with the axis of rotation instead of perpendicular thereto and the cyclone chamber has a tangential inlet of rectangular cross-section.  In a third modification, the cyclone chamber has a tangential inlet dis <PICT:0700781/III/1> <PICT:0700781/III/2> posed in the member 37 and communicates through an oblong slot with an homogenizing chamber containing a set of balls.  Again the liquid may be led into a chamber 2, Fig. 2, having radial liquid directing wings 3 and then through channels 6 to separating discs 7.  The lighter component is discharged through a channel 9 to a paring disc 14 having an homongenizing device and is then recirculated to the chamber 2 through channels 15.  The heavy liquid is fed through discs 16 to a chamber 17 and then through a channel 18 to a paring chamber 19 which has radial wings 21, 22 positioned on either side of the paring disc 20.  In a modification of the above, the liquid is fed into the bottom of the drum and the paring disc 14 has an external outlet communicating with the liquid inlet.  Moreover, the heavy liquid is discharged through a pump which rotates with the drum.  The homogenized liquid which is discharged may be fed to a stabilizing device comprising a valve controlled nozzle communicating with a whirl chamber.
