Abstract: ABSTRACT OF THE DISCLOSURE         A mechanism which maintains drive belt tension substantially constant when the drive belt is mounted on sheaves with a non-fixed center distance such as the sheaves and belt utilized in vibratory earth compaction equipment, shakers and the like where off-centered weights are rotated at high speeds to obtain desired vibrations.  The mechanism includes a driven sheave that is mounted eccentrically on the rotating shaft which supports the off-center weight with the eccentricity of the eccentrically mounted sheave being in the same direction as the offset of the off-center weight.  This arrangement allows the center distance between the drive sheave and driven sheave to remain relatively constant thus retaining the drive belt tension relatively constant.

Abstract: ABSTRACT OF THE INVENTION      This invention relates to fastening devices, e.g., rivets, bolts, etc. which are fabricated from a thermotropic liquid cry-stalline polymer and which contain up to about 50% by weight of a filler material.  The fastening devices are characterized by a shear strength of at least about 15,000 psi (e.g., 15,000 to 75,000 psi and higher), a tensile strength of at least 20,000 psi (e.g., 20,000 to 150,000 psi and higher), a linear coefficient of thermal expansion which is compatible with the materials to be fastened and which ranges from about -3.0 to 3.0 X 10-5 (in/in°C).          The fastening devices of this invention exhibit extremely high chemical resistance to a variety of deleterious materials.  The fastening devices also exhibit a highly oriented skin.  The ther-motropic liquid crystalline polymer utilized has an inherent vis-cosity of between about 1.0 and about 15 dl./g. when dissolved in a concentration of 0.1 percent by weight of pentafluorophenol at 60°C and may be fabricated from a wholly aromatic polyester, an aromatic-aliphatic polyester, a wholly aromatic poly(ester-amide), an aromatic-aliphatic poly(ester-amide), an aromatic polyazometh-ine, an aromatic polyester carbonate, etc. and mixtures thereof.

Abstract: MICROCOMPUTER CONTROLLED LOCKING SYSTEM           ABSTRACT      A locking system is disclosed which comprises a microcomputer  controlled  lock  with  multiple  level keying, i.e. multiple keys having different functions in the locking system.   A key reader,  for example punch card or magnetic type, reads key code into the microcomputer.      A   read/write memory   has   a predetermined  number of  assigned  key codes  stored therein and a read-only memory has a control program stored therein for control of the microcomputer.  An electrically  controlled  actuator  for  the  locking means is coupled  with  an  unlocking  output of  the microcomputer.  The control program comprises a main program and a plurality of subroutines each stored at a  different location  in  the  read-only memory.   A function table has a number of pointers each of which points  to  the  memory  address  of  one  of  the subroutines.  The number of pointers in the function table is equal to the number of locations in the key code memory.  Decoding means operative under program control in conjunction with a control code on the key points to selected locations in the key code memory and the function table corresponding to the control code. The microcomputer,  under control of the main program, compares the primary and secondary key codes from the selected key with the assigned key code at the location in  the  key code memory.   If  there  is a match,  the  microcomputer  then  operates  under  the control  of  the  subroutine  at  the  memory  address pointed  to  by  the  function  table  to  execute  the function of the selected key.

Abstract: SYSTEM FOR DECOMPOSITION OF NTSC COLOR VIDEO SIGNALS                           Abstract NTSC composite color video signals captured in a freeze-frame videoconferencing system can be decomposed into luminance and chrominance components using simple digital addition and subtraction.  The necessary apparatus includes a conventional color camera, an analog-to-digital converter, and a superframe buffer, organized into four field buffers. The analog signal is sampled at phase angles which are displaced at 135 degree increments.  The preferred phase angles are 0, 135, 270, 45, 180, 315, 90 and 225 degrees relative to the phase of the color burst for the current scan line.  Due to the reversal of the color burst phase on a frame-to-frame basis, a luminance or Y value can be obtained for each pel by adding the digital values stored in corresponding pel positions in corresponding fields (odd or even) in two successive frames of the same image.  A chrominance or C value can be obtained by subtracting the same two values.  The I and Q components of chrominance can be obtained directly as a result of the subtraction process at certain of the angles or indirectly through calculation at other of the angles.

Abstract: Les interactions rendent les signatures des sources différentes de celles qu'elles présentent isolément. Pour s'en affranchir, on dresse un catalogue des signatures des sources actionnées séparément, en fonction de paramètres tels que la profondeur d'immersion par exemple. Ensuite, lors d'une utilisation combinée des sources, on mesure la valeur des paramètres et l'on sélectionne dans le catalogue les signatures qu'auraient chacune des sources isolement si les paramètres avaient mêmes valeurs que ceux que l'on mesure. La signature globale du dispositif à grande distance est obtenue par une combinaison des signatures sélectionnées. Application aux traitements d'enregistrements sismiques par exemple.
