Abstract: ABSTRACT OF THE DISCLOSURE                    A scanning system is provided which uses directed light from a scanning element, which directed light is reflected from a curved reflective surface for scanning across a medium with a planar object surface. The scanning element includes a planar reflective facet, such as the planar mirrored surface of a galvanometer, which scans the light across the curved reflective surface in a direction normal to its axis of curvature.  To provide a linear focal line, the planar surface is tilted from its optical axis by a first angle and is off-set for rotation thogonal to the optical axis of the curved surface.

Abstract: Abstract of the Disclosure This invention relates to load-lifting machinery and can find utility when applied to pipe laying cranes made use of in construction  large-diameter pipings.           The pipe laying crane of the invention comprises the under-carriage mounting the framework with the engine and transmis-sion, and mounted equipment.  The mounted equipment incorporates the loading boom with a pipe hanger, the counterweight and the hoist which is connected to the loading boom and to the pi-pe hanger through a system of tackles.  The undercarriage is made sectionalized, i.e., it is composed of the two track bogie arranged on both sides of the framework, one of said bogies carrying the loading boom. The latter bogie is connected to the other bogie with a possibility of setting motion in the direction square with the frame axis for changing the track gau-ge of the undercarriage.  Besides, the output unit of the trans-mission that imparts torque to the boom-carrying bogie, is made extensible.           The pipe laying crane of the character set forth hereinabo-ve, while in working position (i.e., with the boom-carrying bogie extended), has a greater load-lifting capacity than the prior-art cranes of the same weight, whereas when in the posi-tion with the minimized track gauge between the bogies, the cra-ne is transportable by rail or on trailers with its undercarria-ge in the assembled state.

Abstract: ABSTRACT OF THE DISCLOSURE:               The invention relates to a liquid flow rate metering system on board of a moving craft providing results corrected for faults due to the craft movement.  A flow rate meter is provided for measurement of longitudinal and of trans-verse components of liquid flow rate by reference to the craft, whereas a speedometer system determines longitudinal and trans-verse components of the craft speed with respect to the supporting liquid bottom.  An output data processor derives from the flow rate and the speed measured values a value of longitudinal and of transverse components of the flow rate at relative layer distributions with respect to the bottom. Preferably, a sonar and a flow rate meter use a single acoustic unit in a shared-time operation controlled by a master clock.  Application in the determination of the speed and direction of movement of a body of fluid.
