Abstract: SYNCHRONIZATION FOR PCM TRANSMISSION SYSTEMS              Abstract of the Disclosure At the transmitter the synchronization information is provided by position modulation of the line transitions of at least one bit of a PCM word. The receiver is synchronized to the received coded signal by detecting the position modulation of the bit of the PCM word.

Abstract: ABSTRACT OF THE DISCLOSURE           A vibration detection probe holder for use in measuring the vibration of a shaft employed in rotating machinery such as turbines or generators comprises a stationary probe housing fixed to a bearing bracket or other suitable stationary member.  Upon initial assembly, the housing is accurately positioned in close proximity to the shaft. This probe housing is provided with stop means which determine the exact location of a vibration detection probe when such a probe is inserted in the housing, thereby obviating any risk of contacting the rotating shaft with the probe should such an insertion be required while the shaft is rotating.  The stop means also ensure that any replacement probe will be located the same distance from the rotating shaft as the probe initially provided in the holder thereby ensuring continuing accurate readings obtained from any such replacement probes.          A flexible cable, or a series of sleeves positioned within the housing, provide a means for maintaining the probe in position within the housing.  Sealing means disposed at the radially inner end of the housing prevent the splashing of lubricating oil and any contaminants entrained therein from the rotating shaft into the probe holder.  The close proximity of the radially inner end of the housing to the shaft reduces the risk of lubricating oil from the shaft splashing into the housing if the probe is removed from the holder.

Abstract: ABSTRACT OF THE DISCLOSURE      The storage of pipes hoisted by means of a wire-rope sling tightly noosed around the pipes to form a pipe bundle is facilitated by clamping the rope in the sleeve of the sling choker to lock the tight noose against loosening when the pipe bundle is deposited on a support and disconnected from the hoisting means.  The sleeve bore is of generally keyhole section.  The rope is a sliding fit in the cylindrical portion of the bore so as to be locked in said portion and project laterally into the adjacent channel portion of the bore.  By force-fitting a pin into the channel portion in which the pin is a sliding fit, the rope stretch in the bore is clamped against the cylindrical portion of the bore.

Abstract: ALL ELECTRIC EXCAVATING AND LOADING SYSTEM               Abstract of the Disclosure An excavating and loading system includes a vehicle having a main frame supported for movement over a surface and an excavating wheel assembly at the front end of the vehicle for rotation about an axis extending parallel to the width and perpendicular to the length of the vehicle.  The excavat-ing wheel assembly comprises an axle, two rigid side excavating wheels mounted cantilever on the axle and representing the outermost structural components of the excavating and loading system, and a third rigid excavating wheel supported on the axle between the two side excavating wheels.  An electric motor rotates the excavating wheels so that the digging buckets follow a circular path.  An engine is mounted on the vehicle together with an electric generator driven by the engine for supplying power to the electric motor.  Each of the excavating wheels has a plurality of digging buckets, with the buckets of the side excavating wheels spanning continuously from the outer ends of the assembly to points immediately adjacent supports for the wheels, and with the buckets of the center excavating wheel spanning continuously between points immediately adjacent these supports.  Each digging bucket has a rear wall mounted for movement between a material receiving position and a material discharging position. The movable wall of each digging bucket is positively actuated to the material discharging position during each rotation in response to rotation of the excavating wheel assembly.  A conveyor mounted on the vehicle behind the excavating wheel assembly receives material from the center excavating wheel and carries this material upwardly and rearwardly to a discharge point at the rear of the vehicle.  Material received from the two side excavating wheels is directed to the conveyor for transportation to the discharge point.
