Abstract: Abstract A digital optical record with a data track of data spots and spaces arranged in an improved binary code is described along with a playback apparatus for such record which produces an electrical readout signal of narrow frequency band width.   A greater bit storage density is achieved on the record because the minimum length of the data spots and spaces is increased to the width, W, of a single bit data zone, thereby enabling a readout light beam of a larger diameter.   In addition, the electrical readout signal has an increased signal-to-noise ratio because the maximum length of the data spots and of the data spaces between spots is reduced to 2W reducing the dynamic range over which the signal must be extracted.  The improved code accomplishes these ad-vantages for optical recording by providing data spot to space light transitions in the middle of the bit data zones for "1" bits and by spot to space light transitions at the trailing boundaries of the data zones for "0" bits, except that not light transition occurs at the boundary when the "0" bit is followed by a "1" bit.

Abstract: SOURCE FOLLOWER CIRCUIT USING FETS     ABSTRACT OF THE DISCLOSURE           A source follower circuit using at least one FET in which an end of a resistor element is connected to the gate terminal of the FET and the other end of the resistor element is connected to a signal source which generates a comparatively large AC input signal.  The resistance of the resistor element is determined to be at such a value as to prevent oscillation of the FET which is likely to occur depending on the length of the wiring between the signal source and gate terminal and the length of wiring between the source terminal and a load.

Abstract: ABSTRACT OF THE DISCLOSURE:     A process for the production of copolymers of maleic acid anhydride and vinyl trialkoxy silanes containing C1 to C6 alkoxy radicals in the presence of an initiator. The copolymerisation reaction is carried out with a molar ratio of maleic acid anhydride to vinyl trialkoxy silane of from 1:1 to 1:3, the initiator is added continuously or in portions at the polymerization temperature and the copolymer is worked up.  It has been found that by adding the polymeri-sation catalyst in portions or even continuously during copolymerisation, the copolymerisation reaction can be satis-factorily controlled.

Abstract: Abstract of the Disclosure Spent seed is regenerated in a magnetohydrodynamic power plant through the use of a dry method in which the seed is mixed with pulverized coal and formed into pellets.  The pellets are raised to a temperature below their melting point, and the spent seed, an alkali-metal sulfate, is reduced to the corresponding sulfide.  The sulfide particles are then fed to a fluidized bed through which carbon dioxide and steam are blown, the alkali-metal sulfide thereby being converted to the corresponding car-bonate, which is the desired seed material.

Abstract: CONTROL VALVE APPARATUS FOR A PNEUMATICALLY           OPERATED SERVOMOTOR     ABSTRACT OF THE DISCLOSURE           A control valve for a servomotor having a disc located in a bore of a hub attached to a movable wall.  The movable wall separates a first chamber from a second chamber.  A passage in the disc connects a first passageway with a second passageway in the hub to define a flow path to allow free communication of a first fluid between the first and second chambers.  A plunger located in the bore has a first end with an axial projection extending therefrom which engages the disc and a second end connected to an input push rod.  An input force applied to the push rod moves the plunger which causes the axial projection to deform the disc and interrupt the flow path between the first and second chambers.  Thereafter, further movement of the plunger allows a second fluid to be communicated to the second chamber whereby a pressure differential is created across the wall by the first and second fluids,  The pressure acting on the wall creates a force which moves the wall and provides an output member with an operational force.

Abstract: ABSTRACT OF THE DISCLOSURE   A boat motor exhaust system has an exhaust passage extending through the hub of a propeller of an outboard motor, a Z-motor or the like.  By means of a valve system which is actuated on reversal of the direction of rotation of the propeller, the exhaust gas is discharged into a region outside the suction zone of the propeller when the latter rotates backwards and flows outwardly through the propeller hub in the normal manner when the propeller rotates forwardly.  This provides a significant increase in the propulsion during reverse motion.  In one embodi-ment the valve system comprises a rotary valve closure member at the rear end of the propeller shaft and an auxiliary exhaust gas outlet for discharging the exhaust gas during reverse motion.  In another embodiment, the valve system comprises part of the hub of the propeller, which is movable axially of the propeller shaft, and a closure disc at the rear end of the propeller, which disc closes the exhaust passage on movement of the propeller along the shaft into a first end position and opens the passage on movement of the propeller into an opposite end position.  The movement of the propeller into the first end position opens an annular auxiliary gas outlet opening between the hub and a propeller sleeve forming part of a boat motor.
