Abstract: ABSTRACT OF THE DISCLOSURE In a transportation vehicle control system, a signal is detected from a transposed cable to determine the vehicle position relative to a predetermined speed control zone.  This position data, along with other manual and/or automatic inputs, is fed into a profile function generator whose output is a predetermined singular function of the position and other inputs.  While the vehicle is within the speed control zone, the output of the profile function generator is converted from digital form into analog form and then used to limit the vehicle speed.

Abstract: ABSTRACT OF THE DISCLOSURE:           There is disclosed a machine for automatically forming a knot around an article such as a sausage and the like.  The object to be tied is introduced into aligned tubes, and a thread, a cord or the like is interlaced around the tubes by the following operations:  rotation and translation of a cord pressing member which first presses and then releases the cord, a forward and back movement of a member for retaining the cord, and the forward and back motion of a separator.  The tightening of the cord is brought about by the action of a gripper carried by the separator and by a means for tensioning the cord, while the cord is deposited upon the object by reason of the separation of the tubes.  A cutting means which operates at the end of the cycle cuts off the end of the cord upstream of the knot.  The invention can be used to tie a number of dif-ferent objects as well as sausages.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method is disclosed for the vapor phase epoxidation of ethylene to ethylene oxide which includes intimately contacting an ethylene-containing feed stream with an epoxidizing amount of molecular oxygen epoxidizing agent in the presence of a catalytically effective amount of a novel supported, activated silver catalyst and an effective amount of at least one inhibitor which retards combustion of ethylene to carbon dioxide at a temperature of from about 200°C to about 300°C.        The novel silver catalyst is best described in terms of its method of preparation.  The catalyst is pre-pared by impregnating certain inorganic porous substrates with a specific silver carboxylate/amine complex impreg-nating solution.  The impregnated support is then heated in order to evaporate volatiles, decompose the complex and activate the catalyst.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention relates to a string post for a musical instrument.  In some prior art instrument, buttons or other attachments are connected to the instrument head and the strings engage such attach-ments between the nut and the string posts so that the strings are held close to the instrument head.  While this increases the pressure between the strings and the nut, there is not always sufficient room to use such attachments and they add an additional expense to the instrument.  Accord-ing to the present invention, these problems are solved by providing a novel string post for musical instruments.  Briefly, the present string post has a constantly decreasing diameter from the outer end thereof to a first plane virtually at the instrument head and has an increasing diameter from the first plane to a second plane at the instrument head so as to form a curved shoulder at the base of the post between the first and second planes.  This construction urges a string wrapped around such a string post toward the instrument head until the last wrap seats against the shoulder at the base of the post, virtually in contact with the instrument head.

Abstract: ABSTRACT           This invention is directed to novel polyurethane structures, termed polyurethane mico-bits and the process for their preparation which comprises comminuting a flexible polyurethane foam in an inert fluid, e.g., water.     Attempts made in the past to use particulate polymers in paper to obtain improved properties have met with failure because of the lack of a mechanism for connecting them to the paper's fibers.   Polyurethane micro-bits are characterized by broken and interconnected stands from adjacent portions of the polyurethane cellular structure. These strand portions are tripodal shaped particles having hook-like projections, indentations and flutes formed by the destruction of the foam's thin walled portions. It is believed that these structures provide attachment points for the paper's fiberous component.        Polyurethane micro-bits when incorporated in a paper improve its tear and tensile strength properties and are useful as absorbents to remove such contaminants as phenols from aqueous and gaseous streams.

Abstract: ABSTRACT OF THE DISCLOSURE          In a reactor for cracking heavy hydrocarbon oil through a fluidized bed of particles of natural ores, coke-like materials are deposited on a top of the reactor at pipe inside surfaces of a transfer line from the reactor to a scrubber.  To effectively scour out the deposited coke-like materials, particles of natural ores having a mean diameter of a few hundred µm is made to be contained in an effluent gas from the top of reactor, passing through the transfer line at a concentration of 1 to 40 g/m3. The particles of natural ores have a good effect of scouring out the deposited coke-like materials and can keep the transfer line efficiently clean even with a small amount of the particles of natural ores, decreasing a pressure drop in the transfer line.
