Abstract: ABSTRACT          Plastic copolymers of propylene with linear dienes having conjugated double bonds, in particular with butadiene, characterized by a molar ratio between the dienic units in configuration 1,2 and those in configuration 1,4 higher than 0.2, preferably higher than 1, are disclosed.        Such copolymers are prepared by copolymerization of propylene with linear dienes in the presence of stereospecific catalysts comprising a halogen Ti compound supported on a Mg halide.        The copolymers can be reacted with radicalically polymerizable monomers, thus obtaining functionalized products suited to be transformed into films having good adhesion characteristics.

Abstract: VARIABLE THROW CRANK ARM ASSEMBLY     FOR WINDSHIELD WIPER DRIVE          Abstract of Disclosure In a windshield wiper drive system of the type having a reciprocating drive link and a reversible electric motor, a variable throw crank arm assembly between the drive link and the motor drive shaft including a first arm rigidly attached to the drive shaft, a second arm pivotally attached to the first arm and to an end of the drive link, a guide follower on the second arm, and a guide channel on the motor housing receiving the guide follower.  The guide channel has a circular portion centered on the drive shaft axis and a noncircular escape portion radially outboard of the circular portion and merging therewith at a junction.  When the drive shaft rotates continuously in one direction, the guide follower traverses the circular portion and holds the second arm in a short-throw folded position relative to the first arm.  When the drive shaft rotates in the opposite direction, the guide follower automatically enters the escape portion and concurrently pivots the second arm to a long-throw unfolded position relative to the first arm.

Abstract: WATER AND STEAM INJECTION  IN COGENERATION SYSTEM       ABSTRACT OF THE DISCLOSURE     A control system for a cogeneration plant measures the flow of steam exceeding the requirements of the steam-using process.  Water is injected into the combustion zone of a combustor of the gas turbine portion of the cogeneration system to provide a predetermined reduction in NOx products.  The excess steam is added to the output of the compressor portion of the gas turbine to augment the gas turbine power output due to the augmented mass flow.  The control system reduces the water injection in proportion to the steam flow to maintain the total water flow to the combustion zone at a level which maintains the preferred level of NOx reduction.  In a second embodiment, the excess steam is first injected into the combustion zone with a one-for-one equivalent reduction in water injection.  When the excess steam exceeds the amount required for NOx reduction, the excess is Added to the output of the air compressor for power augmentation.  As the power augmentation steam is added a proportionate reduction is made in the NOx reduction steam to account for the fact that a fraction of the output of the air compressor passes through the combustion zone.

Abstract: "PROCESS FOR THE SEPARATION OF C2+ HYDROCARBONS               FROM NATURAL GAS"                 Abstract of the Disclosure A process for the separation of C2+ hydrocarbons from natural gas under pressure wherein the natural gas is cooled (2, 6), partially condensed, and separated (9) into a liquid fraction and a gaseous fraction.  The liquid frac-tion (10) is subcooled (11) and then expanded into the upper zone of a rectifying column (7).  The gaseous frac-tion (23), after engine expansion (25), is also introduced into the rectifying column (7).  During rectification, a product stream (37) containing essentially C2+ hydrocarbons and a residual gas stream (22) containing predominantly lower-boiling components are obtained.  The residual gas stream (22) is initially heated by heat exchange (11) with the liquid fraction (10) and then heated by heat exchange (21) with the gaseous fraction obtained after partial con-densation.  The residual gas stream is then further heated (6, 2) by heat exchange with the feed stream of natural gas to be partially condensed.  The heated residual gas is then engine expanded (28) and reheated again by heat exchange with the feed stream of natural gas to be partially condensed (2).

Abstract: FACETED REFLECTOR FOR HEADLAMPS   ABSTRACT     A multi-faceted reflector for a headlamp of a motor vehicle is disclosed.  The motor vehicle headlamp has the desired optics, in the form of facets, placed entirely on the reflective surfaces of the reflector.  The reflective surfaces are comprised of a plurality of discrete reflective surfaces having right (i.e., surfaces of a parabolic shape in the vertical plane and being linear or cylindrical in the horizontal plane) parabolical cylindrical surfaces and discrete simple rotated parabolical surfaces.  All of the reflective surfaces are located relative to the light source of the headlamp.  The parabolic cylindrical surfaces, serving as spreading facets create a lateral spread of the light developed by the light source of the lamp, whereas, the simple rotated parabolic surfaces, serving as bending facets, create a shifting, relative to the light source, of the projected image of the light source.  The shifted light forms the compact high intensity portion of the light output of the headlamp which cooperates with the lateral spread light to form a compact light output which serves the illumination needs of the motor vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE    A system is provided herein to detect irregularities in the geometry of railway wheels.  The system has a linearly expanding accelerometer which is solidly joined to the rail underneath its head.  The accelerometer sensitivity is constant over its entire length and generates a voltage proportional to the acceleration of the rail.  For different damages, the rail acceleration takes place in different directions,  The voltage amplitude depends on the type of damage, and evinces opposite initial polarities.          Frequency filtering or frequency analysis permit the determination of further criteria which, together with other weighted criteria, may be used to characterize wheel damage.
