Abstract: TITLE: PROCESS FOR POST-TREATMENT OF TITANIUM DIOXIDE   ABSTRACT:           This invention concerns a post-treatment of TiO2 having pigmentary morphological and granulometric characteristics, the purpose of said treatment to confer to the pigment a compact, uniform and adhering coating with a controllable specific surface.          The process consists of three stages:  1. the surface of the TiO2 particles is activated in a moving bed by treatment with an anhydrous gas at 400°-600°C; 2. the particles are made to react, and in the presence of a carrier gas, and in a moving bed, with one or more chlorides chosen from the group consisting of AlCl3, SiCl4 and ZrCl4, at temperatures between 400° and 700°C; and 3. the particles are treated with a gas containing water vapor at between 200° and 400°C.  During the second stage, the chlorides may be allowed to react with oxygen with con-sequential deposit on the particles of the corresponding oxides.

Abstract: Case 2745 WEDGE TIGHTNESS MEASURING DEVICE             ABSTRACT OF THE DISCLOSURE          A device for determining the tightness of a wedge used to close the slot of a dynamoelectric machine and firmly restrain the conductors installed in the slot, is in the form of a tapping hammer or similar tapping tool.  The head of the hammer contains an accelerometer which outputs a pulse signal having duration representing the time the head is in contact with the wedge.  The pulse signal duration is also related to the tightness of the wedge. Associated electronic circuitry measures the time duration and displays the measured value on a digital display on the hammer unless this display is inhibited.  The strength of each blow is assessed by an integrating circuit which gives an output related to the strength of the blow. If this output is not within predetermined upper and lower limits, defining a "window", the display of the measured time duration is inhibited and instead the display indicates that the blow was too hard or too weak.           The operator quickly learns to strike a wedge with a force that is within acceptable limits, i.e., within the "window".  The display is reset each time a new blow is struck. The device is battery powered and portable and preferably the display shuts off if there is an inactive time duration, say 30 seconds, after one blow is struck.

Abstract: APPLICATION OF:  TIMOTHY J. MORSCHECK     FOR:  AUTOMATIC TRANSMISSION                 A B S T R A C T          Disclosed is a power shift transmission having two input shafts, an output shaft, two countershafts which are first synchronized and clutched with either of the input shafts, and then alternately clutched to the output shaft.  Each countershaft rotatably supports a ratio gear driven by one of the input shafts, a ratio gear driven by the other input shaft, and a drive gear for driving the output shaft.  A reverse gear is rotatably supported by one of the countershafts.  A double acting synchronizer is disposed between the two ratio gears on each counter-shaft for synchronizing and clutching either of the ratio gears to the countershaft.  A hydraulically actuated friction clutch is disposed adjacent the drive gear on each countershaft for clutching the countershaft to the driven gear.  One of the input shafts is a torque converter driven shaft; this shaft drives the ratio gears which are first and second speeds and the reverse gear.  The other input shaft is a torque converter bypass shaft; this shaft drives the ratio gears which are third and fourth speeds.  The transmission utilizes helical gears and the helical angle direction of the ratio and drive gears on the countershafts are such that axial forces on the contact teeth of the gears impart bending stresses on the countershaft which subtract from bending stresses on the shaft caused by radial forces on the contacting teeth of the gears.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of receiving and decoding doubly-encoded, interleaved data occurring in blocks of information words and first and second check words to correct errors occurring due to transmission, includes adding error pointers to indicate uncor-rectable errors, and thereafter checking the number of pointers in each block and protecting against miscorrection of errors. The data are decoded in a first decoder and the information words and first check words are corrected by syndromes using the second check words.  A pointer is added to any words containing uncorrectable error.  Then the words so decoded are deinterleaved and decoded in a second decoder, where the infor-mation words are corrected by syndromes using the first check words.  Here the pointers show the position of any erroneous words to facilitate error correction.  The number of erroneous words in each block, at the second decoder, is determined by counting the associated pointers.  If the number is less than a predetermined value, the pointers are cleared, but if it is greater than that value, the data are regarded as unreliable, and the pointers remain.  Alternatively, all words in the block are given error pointers.  Also, for a given number of erroneous words in each block as determined by syndromes, if the number of pointers is less than a predetermined amount, the entire block is regarded as unreliable and all words are given a pointer.  Finally, uncorrected erroneous words are compensated by interpolation.
