Abstract: ABSTRACT                   PROCESS FOR THE CONTINUOUS HYDROCARBONIZATION OF COAL            Certain phenolic compounds are produced from coal by means of a fluidized bed.  The coal particles are preheated in a dense phase and passed together with a hydrogen-rich, oxygen-free, conveying gas into the lower portion of a fluid-bed at 480°C to 600°C, passing the coal particles and conveying gas up-wards through the bed to produce a condensable vapour and solid char, maintaining the solids in the reaction zone for an average residence time of 6 to 60 minutes while maintaining the average hydrogen partial pressure at about 100 p.s.i. to about 1200 p.s.i., and withdrawing the product vapour and solids.

Abstract: A METHOD OF MAKING A COVERED ARTICLE               ABSTRACT OF THE DISCLOSURE            A method of making a covered article such as an automobile seat cushion is disclosed.  The method includes the steps of forming covering members from a covering material which is impervious to a foam material formed by reacting a foamable composition.  The covering members are sewed together along sew lines to form a cover.  A peripheral edge of the cover is joined to an interior peripheral edge of a locating member.  A plurality of small openings are formed along the sew lines of the cover in the sewing operation.  These openings are sealed so that the foam material produced upon the foaming of the foamable composition cannot flow therethrough.  The cover and attached locating member are positioned in a foaming mold.  The locating member aligns the cover properly with respect to the foaming mold so that a vacuum can be drawn on a die surface of the mold to draw a surface of the cover into contact with the die surface.  A charge of the foamable composition is placed in an interior volume of the cover and the foaming mold is closed.  The foamable composition is reacted to fill the interior volume of the cover with the foam material.  The foam mold is opened and the cover is removed therefrom.  The loca-ting member is removed from the cover.

Abstract: ABSTRACT           A helical scan magnetic recording device is provided with a folded mounting plate in order to permit a tape wrap on the circumference of a tape support mandrel which is intermediate the conventional 180° and 360° tape wraps.  Specifically, the device is provided with a folded mounting plate comprising a body having a substantially planar reference surface for supporting a tape entry guide and a non-parallel, substantially planar exit reference surface for supporting a tape exit guide. The two non-parallel surfaces are coupled together to define a V-block mounting support for the mandrel.  In a preferred embodiment, the entry reference surface and the exit reference surface are each perpendicular to the directions of tape entry onto the mandrel and tape exit off the mandrel, respectively. In addition to permitting the use of intermediate tape wrap angles, this device provides a more efficient and compact structure and permits more precise mounting of critical device components.

Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus are disclosed for modifying command signals representing predetermined positions of a machine. element relative a workpiece as a function of measurable unprogrammed changes in the relative position therebetween.  The machine element is responsive to a servomechanism circuit which in turn responds to a control device producing the command signals to command motion of the machine element to programmed points relative to the workpiece.  The servomechanism circuit produces interrupt signals for transferring the command signals thereto.  A measuring circuit is responsive to the unprogrammed change in relative position between the machine element and the workpiece and is operative to produce feedback signals representing the direction and magnitude of the change in relative position.  A first circuit is responsive to the measuring circuit for producing a first signal representing a current unprogrammed change in relative position with reference to a predetermined point.  A second circuit is responsive to the measuring circuit for producing a second signal representing an estimate of the un-programmed change in relative position during a queuing delay defined by a number of interrupt signals.  A further circuit is operative to modify the command signals as a function of the first signals and the second signals whereby said modified command signals are compensated by the unprogrammed change in relative position and cause the machine element to move to the predetermined positions relative to the workpiece.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved surface traversing apparatus has an anchor finger selectively movable laterally of another anchor finger into near or substantial alignment with an opening in a member for insertion thereinto and includes one or more of the fingers being mounted to a base portion of the platform by a mounting arrangement which allows one finger to be deflected laterally relative to another finger such that the finger being inserted may deflect into exact alignment with the receiving opening by lateral engagement with the sidewall of the opening.  Each finger is resiliently mounted to a connecting member which is, in turn, connected to the base portion of the platform.  The resilient mount for each finger normally centers the finger and allows both pivotal and translatory displacement of the finger relative to the connecting member.  A cylindrical adaptor is fixed to the finger and is radially supported in a circular opening in the connecting member by a resilient O-ring therebetween in mutually opposing radial engagement therewith.

Abstract: Abstract of the Disclosure There are disclosed instruments and methods for measuring the characteristics of only a selected portion of an overall transmission channel.  A test tone is trans-mitted from a test site to a remote facility over a path to be tested, and the received signal is transmitted back to the test site over a return path.  Under ordinary circum-stances, it is not possible to distinguish at the test site between the distortions which arose during the forward and return transmissions.  In accordance with the invention, apparatus is inserted at the remote facility which amplifies the received noise relative to the test tone.  Although additional noise is introduced in the return path, it is usually insignificant relative to the amplified forward-path noise.  The apparatus at the remote facility preserves the test tone and re-transmits it back to the test site because the test tone is required at the test site; several important measurements are dependent upon the phase and amplitude of the impairments a relative to the tone in the signal received at the remote facility.

Abstract: A B S T R A C T           Chlorine dioxide is manufactured by reducing an alkali metal chlorate in an acid medium by means of a gaseous or liquid reducing agent in at least one production reactor, with recycling of the tail gases to the said reactor, in order to dilute the chloride dioxide produced.  In the new process, the tail gases to be recycled are brought into contact with an excess of reducing agent and a sufficient amount of water to reduce virtually all of the chlorine contained in these tail gases to hydrochloric acid, and thereafter the mixture thus obtained, of tail gases after reduction, and of reducing agent, is recycled, at least partly, to the said reactor.  In this way, a large amount of chloride ions, which are immediately available for the basic reaction of production of chlorine dioxide, is introduced at the same time as the neutral gases required for dilution.

Abstract: ABSTRACT OF THE DISCLOSURE     Overlapping, minute regions of magnetization in a recording medium, which are produced during recording and cause distortion of the played back signal, are reduced by encoding the signal in a pulse signal.  She time between pulses is varied according to the amplitude of the signal to be recorded, and when this pulse signal is recorded, the minute regions are reduced to elemental size.  Thus they overlap less and do not distort the reproduced signal by offsetting the zero level.
