Abstract: ABSTRACT            An improved boom section has top and bottom walls formed of sloping plate sections or flanges which define peaks between the side walls.  The peaked configuration of the bottom wall increases the buckling strength of the bottom wall over the buckling strength obtained with a flat bottom wall.  The sloping flanges of the top and bottom walls are disposed at acute angles of between twelve and nineteen degrees to horizontal planes.  If the slope of the flanges is increased to an angle significantly greater than nineteen degrees, the peaks in the top and bottom walls would be disposed relatively far from the central axis of the boom section and would be subjected to excessive stresses upon loading of the boom section.  The boom section is advan-tageously formed with a height-to-width ratio which is greater than one and less than three.  Lateral stability of the boom section is promoted by having slider pad forces applied to the bottom wall of the boom section intersect at a point above the center of the boom section and having slider pad forces applied to the top wall of the boom section intersect at a point below the center of the boom section.  To facilitate slider pad re-placement, access openings are provided in the top walls of the boom sections.  The slider pads advantageously move along stain-less steel strips on the walls of the boom sections.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a process and apparatus for the determination of parameters of particles suspended in a liquid, particularly for the parameters of shaped blood particles.  As the suspension is caused to flow through a capillary there is generated a signal that is characteristic of the number and size of the particles and the information concerning the number of particles passing through it is stored digitally.  The pulses of the signal character-izing the number and size of the particles are selected according to amplitude and time duration.  The amplitude value of the pulses corresponding to the selection conditions are digitally determined and summed, and further a storage area is designated with a digital value of the amplitude for the reception of data concerning the volume distribution of the particles and thus the value of the mean cell volume and the distribution curve of the cell volume are determined simultaneously.

Abstract: ABSTRACT OF THE DISCLOSURE                  An electrical two-way transmission system and method of constructing an electrical coaxial conductor assembly for a tubular fluid conductor composed of lengths of electrically conductive pipe having their ends connected in spaced relation-ship by external couplers, such as a well drill string having screwthreaded coupling collars connecting the ends of adjacent lengths of drill pipe, wherein said pipe and couplers provide an outer electrical conductor. An inner electrical conductor for the coaxial assembly is provided by tubes of thin ductile electrically-conductive material disposed within the outer con-ductor pipe, each inner conductor tube being electrically in-sulated from each pipe length by a complementary sheath of elastic dielectric liner material which envelopes said tube, the extremi-ties of each sheathed tube being flared into conformity with the interiors of the end portions and transverse end faces of each pipe so as to anchor said tube against relative displacement, each sheathed tube being permanently deformed radially outward into contiguous conformity with each pipe interior and its end faces with each liner sheath expanded into sealing engagement therewith. An annular body of elastic dielectric material is disposed between the ends of adjacent pipe or within each pipe coupler and between the flared extremities of adjacent inner conductor tubes for in-sulating said tube extremities from adjacent pipe and coupler surfaces and has contact means for electrically connecting adjacent tubes to each other. The coupling of adjacent pipe deforms the annular body therebetween into fluid tight engagement with the tube extremities and adjacent pipe and coupler surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE    A tracking-error correcting system for use in apparatus of the type wherein signal information is recorded in parallel tracks on a record medium. The correcting system is useful for correcting deviations between the scanning path of a transducer which scans the record medium and the parallel tracks. A ramp signal generator generates a periodic ramp signal of substantially constant amplitude and having a duration which is equal to at least a portion of the time required for the transducer to traverse its scanning path. The level of the ramp signal is changed for successive scans of the record medium. An adjustable transducer support is provided to support the transducer in scanning relation to the record medium and is operative to displace the transducer transversely with respect to a parallel track in response to a drive signal applied thereto so as to align the scanning path of the transducer coincidentally with the parallel track. The ramp signal of changing level is used to produce the drive signal. The level of the ramp signal no longer is changed when the scanning path of the transducer is detected to substantially coincide with a parallel track.
