Abstract: Abstract of the Disclosure An ocean mining system for mining manganese nodules comprises a sur-face subsystem and an ocean bottom subsystem.  The ocean bottom subsystem includes a mobile maneuverable, self-propelled, miner vehicle which picks up, handles, washes and crushes nodules while retaining nodule fines.  The under-water subsystem also includes a buffer which functions to provide temporary storage for nodule material picked up and crushed by the miner vehicle.  The buffer further serves to isolate the miner vehicle from the  dynamics of a pipe string extending down from a surface ship.  All equipment not needed for operation of the miner vehicle is located on the buffer to distribute the weight between the buffer and the miner vehicle in a way that provides maximum mobility of the miner vehicle.  The underwater subsystem also includes a flexible link-age, extending between the  miner vehicle and the buffer.  A flotation block holds the flexible linkage up and out of the way of the miner vehicle during operation of the vehicle.  This flexible linkage permits operation of the miner vehicle within a boundary envelope beneath the buffer as determined by the flexible linkage.  The surface subsystem includes a ship which provides all operational control and maintenance support for the bottom subsystem.  The ocean mining system includes sensors and controls.  The sensors sense the location of the miner vehicle within the permitted area of operation, display the topography of the ocean floor adjacent the miner vehicle and also display all aspects of the movement of the miner vehicle and pick-up and handling of the nodules.  The controls provide active control of every com-ponent of the  ocean bottom subsystem from the surface ship.

Abstract: 38/SOl548 AFT CIRCUIT     ABSTRACT OF THE DISCLOSURE           An AFT circuit for a television receiver automatically adjusts the frequency of a tuner local oscillator, not only on the basis of an error signal provided from an AFT discriminator, but also on the basis of horizontal synchronizing pulses contained in the video signal to which the receiver is tuned.  A synch signal detector detects the presence or absence of the synchronizing pulses.  A control circuit provides a control signal to the local oscillator in response to the AFT error signal when the latter is above or below a reference voltage such that the desired frequency is within an AFT capture range.  However, when the AFT signal is at the reference voltage, the control circuit provides the control signal based on the presence or absence of the synchronizing pulses, such that when the pulses are present, the local oscillator frequency is raised, but when the pulses are absent, the local oscillator frequency is lowered.  Then, when the AFT signal is present, the local oscillator is controlled thereby.  This AFT circuit has an expanded effective capture range, and is prevented from locking onto the sound carrier of an adjacent channel.

Abstract: BLOCK COPOLYMERS AND PROCESS FOR THEIR PREPARATION             ABSTRACT OF THE DISCLOSURE Under particular conditions, a cationic ring-opening polymerization of an (single) oxirane monomer selected from the group consisting of an acyclic glycidyl ether, a cyclic glycidyl ether, and a haloalkyl epoxide, in thepresence of a hydroxyl-terminated prepolymer ("HTP") and a particular catalyst, produces a polymerization having 'living polymerization' character-istics, provided the the OH groups are aliphatic OH groups and not aromatic OH groups. The result is an AB or ABA type block copolymer the molecular weight (mol wt) of which is directly proportional to the conversion of the monomer to the block copolymer. The HTP which may be a mono-, di-, tri-, or tetra-hydroxyl-terminated prepolymer, serves as a chain propagator which initially furnishes OH groups as propagation sites. Linear block copolymers or branched Mock copolymers are formed, depending upon the structure of the HTP. Where one segment of an AB or ABA type block contains halogen, the segment may be aminated.  If the other segment is hydrophobic, the aminated block copolymer is amphiphilic.

Abstract: ABSTRACT OF THE DISCLOSURE      A four-way valve for selectively controlling the application of fluid and exhaust pressures to opposite sides of a double acting cylinder utilizes a main valve spool that is axially movable in a valve housing defining ports respectively connected to opposite sides of the cylinder and to the pressured and inlet sides of a fluid pressure source.  The spool valve is provided with an axial bore and a pilot spool is mounted in such axial bore.          Radial passages are provided in the main valve spool connecting its exterior with the axial bore and external sealing portions on the pilot spool cooperate with the radial port so that in a neutral position of both the main valve spool and the pilot spool, no fluid flow occurs.          Upon axial shifting of the pilot spool in either direction from the neutral position, fluid pressure is applied to opposite ends of the main valve spool to cause it to follow the pilot spool and thus effect a connection between the outlet and inlet ports of the fluid pressure source and the appropriate side of the double acting cylinder.

Abstract: ABSTRACT OF DISCLOSURE     A toy vehicle has a gear box containing a clock spring which is wound by pushing the vehicle backward. A two part toggle-linkage system connects the gear box to the frame.          When the clock spring is wound, the resulting spring bias urges the toggle-linkage system to one over center position which locks the gear box in order to preserve the energy stored in the wound spring.  When the toggle-linkage system is pressed near its center, it moves over center to another position, which unlocks the gear box and releases the energy stored in the wound spring in order to propel the vehicle.          When the vehicle is next moved backward, the toggle-linkage returns to the locked position which once again locks the gear box.
