Abstract: Abstract of the Disclosure The invention concerns a process for the production of copolymers of propylene and but-1-ene wherein the proportion by weight of units derived from but-1-ene is from 10 to 40% and wherein the proportion of isolated ethyl branches is at least equal to the square of the proportion of units derived from propylene contained in said copolymers. The process is characterised in that a gaseous mixture of propylene and but-1-ene is brought into contact, in the absence of liquid diluent, with a catalytic system which is stereo-specific in the polymerisation of propylene alone. The resulting copolymers can be used for the production of hollow bodies or heat-sealable films.

Abstract: A BATON PASSING METHOD AND APPARATUS FOR MAINTAINING SYNCHRONIZATION IN A  TDMA SATELLITE COMMUNICATION SYSTEM                       Abstract In a TDMA satellite communication system, one of the stations is-elected the primary station which transmits a reference burst to all other stations to synchronize the local clocks in each station.  Each subsidiary station in turn responds by transmitting a local trans-mit reference burst to enable synchronization of the local transmit clocks.  In order to assure that the synchronous operation of the network will continue when the reference station experiences a failure, an alternate reference station is designated in the network which will assume the role of the primary reference station in a baton passing operation in the event that the existing primary reference station must abdicate its reference role.  An improved method and apparatus for carrying out the baton passing operation monitors the channel error rate at the reference station and the alternate station. The error rate is measured by detecting FEC from as-sessing the error syndromes in the reference bursts from the reference station as received at the reference and alternate stations.  This refined monitoring technique is combined with the coarser technique of monitoring the number of negative acknowledgement signals from the subsidiary stations indicating that they have not correctly received reference bursts, to yield a more refined determination at the reference stations of its effective-ness as a reference station.  The alternate station uses a similar technique to determine if it is sufficiently healthy to play the role of alternate station.            In addition all earth stations equipped with the channel error rate measuring device can inhibit their operation during extreme channel error conditions.

Abstract: Grapple System for Log Skidder Abstract Load skidding vehicles commonly include a grapple assembly which under load conditions can pivot rearwardly about its support point resulting in disproportionate loading of the rear wheels and consequently instability of the vehicle.  A connecting member is pivotally attached between the grapple and a hydraulic cylinder which is attached to the skidder.          Operation of the hydraulic cylinder causes the grapple to rotate about its support pivot.  The hydraulic cylinder may be locked causing the grapple to be locked in relation to the boom assembly.  During load hauling operations this mechanism is used to lock the load in a position near the vehicle resulting in increased stability.  The mechanism is also of use in positioning the grapple assembly with respect to the load prior to grasping it.

Abstract: ABSTRACT OF THE DISCLOSURE A horizontal fluid-operated motor wherein the foremost end of the horizontal piston rod is connected with the feed ram of an incinerator and with the front end portion of a hollow tubular shroud which spacedly surrounds the piston rod in each axial position of the latter and whose rear end portion permanently surrounds but is movable axially of the cylinder of the motor.  The cylinder and the shroud define a narrow ring-shaped clearance which admits air into the interior of the shroud when the piston rod performs a forward stroke and which permits expulsion of air from the interior of the shroud when the piston rod performs a return stroke whereby the outflowing air entrains impurities which might have penetrated into the shroud.  The shroud extends, without any or with minimal clearance, through the opening of a transverse wall at the front end of the cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE     The furnace has a feeding channel through which firewood is transported into a fire chamber.  A steam pipe leads into the channel.  Through said pipe, steam is intro-duced into the solid fuel material in bursts as soon as a certain temperature is exceeded within the said channel.          The steam increases the humidity in the air and the moisture of the firewood, thereby reliably preventing a spreading of the fire within the feeding channel, without simultaneously impairing combustion within the fire chamber.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides an improvement in hose clamps of the type employing a worm screw mounted in a housing which is fastened to a metal band and engages in slots in the band.  A thin backing layer is laminated to the metal band of the clamp on the face that engages the article to be clamped, for example, to prevent extrusion of hose materials through the slots.  This backing layer is of a thickness such that it will be stretched by the screw thread lands, but is thick enough that it will not break or crack under such treatment.  It is slightly narrower than the band material, so that it can be applied without protruding and form dangerous knife edges, and is fixed to the band by means of a resilient adhesive that will permit the required deformation without separation.  The screw thread lands can now be made deep enough for positive engagement in the slots and even protrude slightly from the other side.  This improved clamp can be manufactured by a continuous process of drawing a strip of metal from one coil, stamping runs of slots in it, drawing a backing strip from another coil, laminating the two strips together by means of a thin double sided adhesive tape that is interposed between them, cutting the resulting laminate into suitable band lengths, and then mounting the housing and screw thereon.

Abstract: D-23,728 ERROR RATE DETECTOR by Robert A. Karchevski Abstract of Disclosure One or a burst of error signals from an error detector are applied to one input of a latch.  The first error received during a "window" forces the latch to a set position, and a subsequent enabling pulse reads the error occurrence into the count up input of an up-down counter.  Following the enable pulse, the latch is reset.  If one or more errors occur during the subsequent window period, another error ocurrence is read into the count up input.  Otherwise, the occurrence of the enable pulse reads the absence of an error into the down count input of said up-down counter.  On a full count, an output latch circuit is set by an output signal from the counter.  The latch is not reset until a zero count is obtained in the up-down counter.  Overflow and underflow are prohibited by circuits external to the up-down counter.

Abstract: ABSTRACT         A directional drill attached to a drill string having periodic concentric collars is advanced in an inverted arcuate path to form a pilot hole underneath an obstacle followed by a larger concentric washover pipe.  When the washover pipe reaches the surface on the other side of the obstacle a first reamer is attached to the end of the washover pipe exiting the drilling path, a second reamer of smaller diameter than the first reamer is attached to the other end of the first reamer by means providing for some separation between the two reamers, and a production casing of smaller diameter than the second reamer is attached to the other end of the second reamer with a swivel.  The remaining length of the first portion of casing is supported some distance above the ground on rollers located above and beyond the exit point of the pilot hole.  The reamers are operated by rotating the washover pipe and simultaneously drawing the washover pipe through the pilot hole.  As the reamers are drawn through the pilot hole the first reamer enlarges the hole to a diameter greater than that of the casing.  Drilling mud pumped through the washover pipe exits at the reamers to entrain the dislodged earth and the second reamer compacts it to form a bushing around the sides of the enlarged hole to lubricate the passage of the casing. The reaming operation may be performed without the production casing attached to the reamers followed by a second reaming operation with the casing attached in order to complete the installation.
