Abstract: IMPROVED SKID CONTROL SYSTEM            Abstract of the Disclosure:  A skid control system is provided for use with a vehicle having a pair of spaced apart wheels and having a braking system for applying braking forces to the wheels.  A brake control circuit responds to a skid signal obtained from any one of a plurality of in-cipient detector circuits to act upon the braking system to release the braking forces.  A delayed skid signal is provided whenever the difference in wheel speeds of the two wheels exceeds a given amount.  A delayed skid signal is also provided if the average wheel speed of the two wheels de-creases at a rate greater than a desired decreasing rate. If both wheels decelerate, a skid signal is provided upon sensing that the faster wheel is decelerating at a rate greater than a reference rate.  As the wheels spin-up toward an ideal velocity for a braked vehicle, an accelera-tion detector serves to insure wheel roll up on low friction surfaces.  If the wheels spin up at an acceleration greater than an acceleration level, the acceleration detector output is inhibited.  If the acceleration is less than the preceed-ing level and more than a second level, a skid signal is provided.  Also, as the wheels spin-up to a desired velocity, braking forces are restored when the rate of acceleration declines below the second acceleration level.  Monitoring circuits are provided for monitoring various operations of the skid control system and deactivate same when the operation is not within prescribed limits.

Abstract: ABSTRACT OF THE DISCLOSURE:            A process for the production of 1,1-difluoroethylene by photochlorinating 1,1-difluoroethane to form 1,1-difluoro-1-chloro-ethane and heating the reaction products obtained to temperatures of from 550 to 750°C.  The process is characterised in that the difluoroethane used is an unpurified reaction product of the cata-lytic hydrofluorination of acetylene and contains up to 3 % by vo-lume of acetylene and at most 8 % by volume of vinyl fluoride.          Despite the presence of impurities, namely acetylene and vinyl fluoride, in the starting product, yields of 1,1-difluoroethylene amounting to more than 90 %, based on the acetylene used, are ob-tained where this process is applied.  Accordingly, the secondary products present, particularly the unreacted acetylene, have hard-ly any effect upon the reaction as a whole.  This is surprising in-sofar as it was not known that gas mixtures containing acetylene could be photochlorinated without difficulty.

Abstract: A  method of making a cigarette having a core of one grade of tobacco and at least one substantially circumferential wrapping of a second grade of tobacco which comprises applying to a moving base or conveyor  a first stream of the core tobacco and a pair of second streams of the wrapping material, one stream of wrapping material being on either side of the first stream.  The three streams are then deposited onto a moving support which is at an angle to the base  such  that one stream of wrapping material is deposited upstream of the core material  which,   in turn, is deposited upstream of the other stream of wrapping material.  The composite layer thus formed is then formed into a tobacco cord in a known manner.  The latter is then formed into cigarettes in the usual way. A modification of known cigarette-making machines is described which is particularly adapted for carrying out this method.

Abstract: CUTTING APPARATUS                ABSTRACT OF THE DISCLOSURE        A pair of cylinder arbors have a plurality of arcuate cylinder segments extending circumferentially around a portion of the arbor.  The segments are adjustable relative to the arbors in a circumferential direction.  Each of the segments has a respective cutting and/or scoring die plate secured thereto.   The die plates are relatively thin plates having lands formed thereon which cooperate with lands formed on the die plates on the other arbor to cut material moving through a nip defined by the segments.  The material is cut by the lands into carton blanks for example, and broke.  The broke is suitably separated from the carton blanks.  The segments on one of the cylinder arbors carries a movable broke removing mechanism which includes pins which engage the broke.  The pins extend through openings in the segments and die plates thereon and are actuated by an axially movable cam bar which is actuated from a suitable cam.          Further, a mechanism adjusts the cylinder arbors toward and away from each other for various carton blank print lengths.  The segments which are positioned on the arbors are changed also for different print lengths.  Specifically, different radial thickness segments are mounted on the arbors.  Further, the apparatus is provided with an on-the-run adjustment mechanism for adjusting the radial dimension between the dies at the cutting nip.

Abstract: ABSTRACT OF THE DISCLOSURE          An oil film bearing for a roll neck in a rolling mill, wherein a sleeve with a tapered bore is mounted on a tapered section of the roll neck for rotation therewith, the sleeve being journalled in a non-rotatable bushing contained in a bearing chock.  During rolling, a film of high pressure oil is maintained hydrodynamically between the sleeve and bushing at the bearing load zone.  In order to provide lubrication at the roll neck/ sleeve interface, a portion of the hydrodynamic oil is bled from the sleeve/bushing interface via holes extending radially through the sleeve into a plurality of longitudinal primary grooves in the sleeve bore.  This conventional arrangement is improved by the addition of a plurality of secondary grooves in the sleeve bore.  Oil is forced from the primary grooves into the secondary grooves via connecting grooves in the sleeve bore.  The inter-connected primary, secondary and connecting grooves form a plurality of discrete circumferentially isolated groove networks which are sequentially charged with high pressure oil as each rotates through the bearing load zone.  The connecting grooves create a pressure differential which opposes reverse flow of oil from the secondary grooves into the primary grooves as a result of centrifugal force acting on the groove networks rotating through the unloaded zone of the bearing.

Abstract: ABSTRACT         The invention relates to an automatic transmission for use in motor vehicles.  The automatic transmission comprises a mechanical transmission, gear synchronizer and clutch which have been automated by the addition of electro-mechanical and pneumatic operators and an analog and digital electronic control system.  The electronic control system receives operator commands regarding the mode of transmission operation (either automatic or manual) and monitors throttle position, engine speed, transmission countershaft speed, drive shaft (vehicle) speed and rates of change of these speeds.  By utilizing this information, the electronic control system selects the optimum transmission gear ratio, effects synchronization of the selected transmission gear elements and controls clutch engagement according to a logic program which represents an empirical compromise between conflicting design criteria and operating parameters such as maximum fuel economy, optimum engine/vehicle speed ratio, minimum nuisance shifts and minimum vehicle noise.
