Abstract: FM STEREO APPARATUS AND METHOD                       ABSTRACT         An output matrix adapted to receive an L+R signal component (made up of the sum of L and R stereo components) and an L-R signal component, and to combine these in a manner to produce a separate L output and a separate R output, with certain modifications to the outputs.  The higher frequency portion of the L-R signal is passed through a detector which, in turn, causes a leading edge amplifier to transmit to the matrix only those signal portions where there is a relatively abrupt change of amplitude, these being the signal portions which contain the main stereo information which gives the directional information.  Also, the L+R signal component, in addition to being transmitted directly to the matrix, is directed through time delay means to produce a time delayed L+R signal component that is also transmitted to the matrix, so as to provide what are called "ambient" sounds to the output of the matrix.

Abstract: METHOD AND APPARATUS FOR NORMALIZING THE SPEED OF AN ELEMENT POSITIONABLE BY A SERVOMECHANISM               ABSTRACT OF THE DISCLOSURE A speed normalization circuit for eliminating the need to fine tune a servomechanism, such as a daisy wheel printer, after manufacture, for example, in order to compensate for speed variations caused by tolerance variations throughout the manufacturing process and evidenced by variations in the actual print wheel speed and the actual carriage speed, is disclosed.  In opera-tion, when a restore sequence is called for (power up, remote restore, cover open/resume, check/resume), the carriage is restored to the leftmost home position and is then stepped three times by an identical amount (twelve increments, l/120 of an inch per increment). The average value of the actual carriage speed for these three movements is determined and a compensation value is selected.  If the carriage speed is too slow, the nominal speed value stored in a read only memory look-up table is incremented by a fixed value (i.e., plus one, two, or three units); if the speed is too fast, the nominal speed value is decremented by a fixed value (i.e., minus one, two, or three units).  The compensa-tion value is added to the nominal speed value during subsequent actual operation of the servomechanism.  For the print wheel, there are two programmed movements upon restore, namely, one half rotation in each direc-tion (one forward, one reverse) for a total of ninety-six increments per movement.  The speed compensation value is calculated in the same manner.  Other features are also disclosed.

Abstract: ABSTRACT             This specification is directed to a method of making a compound of the formulation M MnxOy where M is bismuth or lead.  The method is characterized by the following steps.  A solution is formed by mixing Mn(NO3)2 with a nitrate of M.  The solution is main-tained at a relatively constant temperature and NaO"?" is added to the solution, whereby Mn(OH)2 and a hydroxide of M form a suspension.  While the suspension is being agitated, oxygen is passed through the suspension, where-by the Mn(OH)2 and the hydroxide of M can react to form M MnxOy.  The suspension is filtered to recover the M MnxOy compound.  Thereafter, the compound is washed with water and dried.
