Abstract: 762,080. Coated semi-permeable membranes. YARDNEY INTERNATIONAL CORPORATION. Oct. 15, 1952 [Oct. 17, 1951; May 2, 1952], No. 25904/52. Class 140. [Also in Group XXXVI] A battery separator consists of a semipermeable membrane of regenerated cellulose or other material to which is applied a coating of a thermoplastic substance incorporating an ion exchanger. Cation or anion exchangers may be used in the coating and if the exchanger is a film-forming material it may be applied directly to the semi-permeable membrane. The coating may also include a polyacrylate. The coating may consist of polystyrene, polyvinyl resins or styrene and butadiene copolymers and may be treated with sodium or potassium chloride to reduce its electrical resistance. The ion exchanger may consist of a sulphonated styrene or other resin or of sulphonated casein, zein, polyvinyl alcohol or acetate or regenerated cellulose. In an example casein is dissolved in sulphuric acid, precipitated with potassium hydroxide and the precipitate dissolved in weak sulphuric acid. The semi-permeable membrane which may. consist of regenerated cellulose is then dipped in the solution. Instead of casein zein may be dissolved in sulphuric acid in the presence of silver oxide as a catalyst. In another example the membrane is dipped in a solution obtained by dissolving polystyrene in sulphuric acid and removing the free acid by dialysis. In a further example the membrane is dipped in an emulsion of polyvinyl acetate containing sodium or potassium methacrylate and a sulphonated styrene cation exchange resin.

Date Jun. 6, 1985.Digital signals which are sent each with their own frequency are corrected for frequency-dependent attenuation of the transmitting medium in a filter (5) so as to maintain a desired relationship between the amplitudes of the signals after the filter. Difference circuits (6) which have output signals (US1, US2, US3) control the filter means, obtain signals (Uf0) on their first inputs from a common voltage supply circuit (9) and signals (Uf1, Uf2, Uf3) on their second inputs from a voltage supply circuit (10) for each of the output signals. A decoder (18) sends a control signal (S0, S1, S2, S3) associated with the respective digital signal. The control signals reset switches (17) whereby the voltage supply circuits (9, 10) obtain signals from an amplitude detector (13) corresponding to the respective frequency in the transmitted signal. Each of the output signals (US1, US2, US3) fed to the filter (5) by the difference circuits (6 ) thus corresponds to a digital signal.

Abstract: SYNERGISTIC TRACKER                 ABSTRACT OF THE INVENTION Target  tracking  capability  is  provided  by  a synergistic tracker system (5) which includes both a correlation tracker (30) and an object tracker (40) for processing sensor data input (10)  and for generating tracking error signals (80).   The  operation of  the synergistic tracker system is controlled by central processing unit  (70).   The system operates by first correlating a reference region image with a portion of a current digitized image provided by analog to digital converter (20).  Secondly, the object tracker provides a precisely defined trackpoint for an object within the current image.  The correlation tracker stabilizes and limits the portion of the digitized image that the object  tracker must  operate upon.   Stabilizing  and limiting this portion of the digitized image reduces the object tracker's sensitivity to background clutter and sensitivity to a loss of lock induced by sensor motion.   The object tracker provides a non-recursive update for the correlation's reference region image. The correlation tracker and the object tracker are used simultaneously and cooperatively so that the strengths of a one tracker are used to overcome the weaknesses of the other.  The invention achieves a greater tracking tenacity,  a reduction in tracker angle noise,  and a reduction in hardware complexity.

Granted: 2000-11-14
Abstract: A high gain, single-pass free electron laser (10) formed of a high brilliance electron injector source (20), a linear accelerator (30) which imparts high energy to the electron beam, and an undulator (40) capable of extremely high magnetic fields, yet with a very short period. The electron injector source (20) is the first stage (gap) of the linear accelerator (30) or a radial line transformer driven by a fast circular switch. The linear accelerator (30) is formed of a plurality of accelerating gaps arranged in series. These gaps are energized in sequence by releasing a single pulse of energy which propagates simultaneously along a plurality of transmission lines, each of which feeds the gaps. The transmission lines are graduated in length so that pulse power is present at each gap as the accelerated electrons pass therethrough. The transmission lines for each gap are open circuited at their ends. The undulator (40) has a structure similar to the accelerator (30), except that the transmission lines for each gap are substantially short circuited at their ends, thus converting the electric field into magnetic field. A small amount of resistance is retained in order to generate a small electric field for replenishing the electron bunch with the energy lost as it traverses through the undulator structure (40).
