Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a device for taking bottom soil samples from a deep water basin.  The device includes, a frame, a leader rod accommodated in the frame and provided with a float at the top, a sampling element located at the lower part of the leader rod and made in the form of a grab with normally open jaws, and ballast weights removably suspended from the frame and weighing enough to lower the device in the water of the basin until the lower end of the leader rod strikes the bottom of the basin.  The grab jaws are closable, and the ballast weights are removed from the frame when the leader rod strikes the bottom of the basin by a mechanical lock joint which connects the weights with the leader rod so that when the leader rod strikes the bottom the lock jointsshifts the weight to an unstable state and they are removed from the frame.  Containers are articulated at lower points on the jaws of the grab in a state of labile equilibrium and are filled with the ballast weights of a preset mass, and a system of levers having one end connected with the leader rod and the other end bearing against the containers for holding them in an initial position and for releasing them at the moment when the leader rod strikes an obstacle.  The leader rod is movable in an axial direction.

Abstract: STRETCHABLE BELT CONVEYOR                ABSTRACT OF THE DISCLOSURE     A stretchable U-shaped conveyor belt with reinforcing members extending transversely of the belt and spaced apart longitudinally of the belt. Elastic stretchable material betweeb the reinforcing members permits prestretching the blet so that the edges remain in tension when the belt passes around curves and thereby maintains the molded shape of the belt in horizontal and vertical curves.  The conveyor belt is driven by a power belt and guided by guide rollers.  The power belt and conveyor belt are carried by support rollers mounted on frames at spaced-apart positions along the belt path.          The frames are fastened to a resilient, flexible spine member which provides for positioning of the frames around vertical and horizontal curves. The U-shaped cross section of the belt is also maintained by U-shaped reinforcing members of high modulus material which are positioned in two spaced layers within the molded body of the belt.  Layers of cords of low modulus textile material between the reinforcing members provide resistance to tearing and strengthen the belt for holding fasteners as well as increase the effectiveness of the U-shaped reinforcing members.

Abstract: ABSTRACT OF THE DISCLOSURE         A servo system is disclosed for use with a motor such as the drive motor for the head wheel of a recording and reproducing apparatus, for example.  The servo system utilizes a phase comparator to phase lock a feedback signal supplied by a motor tachometer and a reference signal to control the phase and speed of the drive motor.  The reference signal is generated by a digital processor which is adapted to adjust the phase of the reference signal to a predetermined lead relative to a standard frequency source and also includes means for adding or subtracting incremental phase adjustments by comparing the phase of said tachometer signal with the phase of said standard frequency source and providing error signals in said incremental amounts for adjusting the resulting reference signal that is applied to the tachometer phase comparator.

Abstract: CONSTANT PRINTING PRESSURE MECHANISM FOR PORTABLE LABEL PRINTING AND APPLYING MACHINE, OR THE LIKE            ABSTRACT OF THE DISCLOSURE           The disclosure concerns a constant printing pressure mechanism for a portable label printing and applying machine.  The machine has a printing head which is interlocked to move with a hand lever.  It has a platen that carries a label strip and that is disposed opposite to the printing head.  The constant pressure mechanism turns the platen up against the type faces of the printing head with a constant pressure in synchronism with the downward movement of the printing head.  The platen is slightly released from the printing head immediately after the printing operation.  A linkage is connected with the hand lever for moving inking rollers across the type faces of the printing head and then out of the way of the type faces at printing time.  The label strip of labels to be printed is fed to the platen by a feed roller, and the feed roller is rotated a desired distance for each label imprinting and the roller is mechanically blocked against inertial overrolling.  The label strip is separated from the backing strip therefor by formation of a loop of the backing strip.  A device regulates the size of the loop formed in the backing strip at the point it is peeled from the overlying label strip.

Abstract: COMPARTMENTALIZED GAS INSULATED        TRANSMISSION LINE     ABSTRACT OF THE DISCLOSURE          A gas insulated transmission line section wherein an inner conductor at high potential is located within an outer sheath at low potential.  An insulating gas is disposed within the outer sheath to electrically insulate the inner conductor from the outer sheath.  A support insulator is dis-posed within the outer sheath, and this support insulator supports the inner conductor in a spaced-apart relationship with the outer sheath.  Included is a barrier insulator which also supports the inner conductor within the outer sheath.          The barrier insulator substantially fills the cross-sectional area between the inner conductor and the outer sheath so as to prevent substantially all arc products and contamination produced in the unlikely event of a fault from migrating past the barrier insulator.  By so preventing the migration of these products, the gas insulated transmission line section is effectively compartmentalized and these products cannot contaminate adjacent transmission line sections.
