Abstract: PROCESS FOR PREPARING POLYETHYLENE BLEND FILM        ABSTRACT OF THE DISCLOSURE          There is disclosed a modified method of preparing a blown polyethylene film made from a blend of major proportion of a polyethylene resin, e.g., LLDPE, a minor proportion of a second polymeric resin, e.g., polystyrene, and at least one additive, e.g., a colorant.  The additive or additives are mixed with the second polymeric resin and the resulting mixture is then blended with the polyethylene resin, thereby reducing the number of process steps. Also disclosed is a method of monitoring and/or controlling the second polymeric resin content in the film made with known proportions of a colorant and the second polymeric resin by measuring the light transmission of the film.

Granted: 1992-08-04
Abstract: ABSTRACT    A clamping head is equipped with angular spreading bodies which engage a winding core.  Impingement of the winding core end face on a stop moves the spreading bodies longitudinally on a bevel of the clamping head core against spring force, thereby spreading the spreading bodies so as to engage the inside circumference of the winding core.  To that end, the clamping head features a sleeve-shaped part which centers the winding core and is provided with longitudinally extending slots for the angular spreading bodies.  A shank of each spreading body, extending radially outward, forms at least indirectly the stop for the winding core end face.  Longitudinally movable in the slot, the other shank of the spreading body has a projection which protrudes radially inward and interacts with the bevel of the clamping head core so as to cause the shank to move beyond the peripheral surface of the sleeve-shaped part as the projection runs onto the bevel.  The clamping head secures the winding core in both nonpositive and form-fitting fashion in that the spreading body shanks dig into the winding core.  It is distinguished by a design from components which are relatively simple to manufacture and of which the spreading bodies exposed to wear can be replaced easily.

Title: Selective ammoniacal pressure leaching of noble metal  concentrates
Inventor: TAN KHAY G
IPC: C22B3/14
Filed: 1988-01-12
Granted: 1993-11-02
Abstract: "SELECTIVE AMMONIACAL PRESSURE LEACHING PROCESS"                 ABSTRACT OF THE DISCLOSURE      A process is disclosed for the recovery of metal values from copper-, silver- and selenium-containing material, such as copper refinery anode slimes and noble metal concentrates, which includes initially subjecting the material in finely divided form to oxidative pressure leaching in aqueous ammoniacal solution at a temperature and for a sufficient period of time until the resulting leach solution contains a major portion of the copper and selenium contents of the material, the reaction conditions being insufficient to dissolve a major portion of the silver present.  The process facilitates treatment of complex materials since the leach solution and residue can separately be subjected to any suitable combination of downstream processing steps to recycle reagents and to recover separated metal values in a highly efficient manner.

Granted: 1993-06-29
Abstract: ABSTRACT     Monitoring Tension in an Elongate Flexible Member A method of monitoring the tension in a flexible drive belt     which passes around a plurality of pulleys includes the steps of causing a portion of the belt     when installed around the pulleys to vibrate at a natural frequency and detecting that frequency.  In one arrangement the belt     is set into a vibrating motion by an impulse and the frequency of the transient vibrations measured.  In another arrangement the belt is vibrated by a drive mechanism which receives a drive signal derived from the belt movement.       Specific methods and apparatus for monitoring the tension are also applied to measuring the tension in elongate flexible members other than drive belts.

Abstract: ABSTRACT OF THE DISCLOSURE A spall backing material contiguously attached to an armor plate at least suppresses the formation of lethal armor spall from being propelled from the inner surface of the armor plate when the outer surface of the armor is impacted by a weapon with sufficient impact to release high velocity spall from unprotected armor.  When the impedance of the spall suppression armor is equal to or greater than the impedance of the armor plate, the formation of lethal spall in the armor will be prevented. When the spall backing material is reduced in thickness to minimize weight and has an impedance lower than that of the armor plate, or a more powerful weapon is used, armor spallation will occur but will be suppressed by the spall backing material to minimize lethality.

Abstract: POWER DRIVEN TRAILED SKIDDER VEHICLE Abstract A trailed skidder vehicle driven from the power take-off of a tractor or other power driving vehicle performs the operations of a conventional skidder.  The trailed skidder vehicle has an elongate structural frame supported by an axle and set of wheels at the rear end of the frame.  The axle includes a differential drive for coordinated drive of the set of wheels.  A load bearing superstructure arch-like support extends above the frame adjacent to the rear end.  The arch support is constructed with braces on the frame for transmitting forces from a load applied at the top of the arch support to the axles.  A superstructure cable bearing such as a cable roller arrangement or fairlead is mounted on the arch support for guiding and bearing a timber skidding cable.  A winch is mounted on the frame forward of the superstructure arch support for extending and retracting a timber skidding cable over the cable bearing or roller arrangement.  A number of structural features are incorporated for power driven operation in coordination with a tractor or other power driving vehicle.  In an alternative embodiment a boom or grapple boom is pivotally mounted on the superstructure arch support with a grapple or jaw mounted at the free end of the boom for grapple skidding down timber.  Grapple skidding capability may be combined with cable skidder ability on the trailed skidder vehicle with the cable bearing fairlead rollers mounted below the grapple boom on the arch support.

Granted: 1995-08-01
Abstract: The  invention  relates   to  an  improved process for producing furnace carbon blacks wherein a fuel and an oxidant are reacted so as to provide a stream of  hot  primary  combustion  gases  possessing sufficient energy to convert a carbon black yielding liquid hydrocarbon  feedstock  to  carbon  black,  and wherein liquid hydrocarbon feedstock is peripherally injected,  in  the  form  of  a  plurality  of  non-preatomized coherent streams or preatomized streams, into the stream of gaseous combustion products at a point where  the  combustion gas  stream has  reached maximum  velocity   in   a   direction   substantially transverse to the direction of flow of the stream of combustion  gases  and  under  sufficient  pressure  to achieve a degree of penetration required for proper shearing and mixing of the feedstock.   The feedstock is decomposed and converted into carbon black prior to  termination  of  the  carbon  forming  reaction  by quenching,   and   then   cooling,   separating   and recovering the resultant carbon black.   According to the  invention,  a  sufficient  portion  of  the  total amount of liquid hydrocarbon feedstock is introduced into the combustion gas stream prior to the point at which the stream of combustion gases reaches maximum velocity and at a point upstream of which no further increase of the CDBP of the resultant carbon black caused by injecting feedstock into the hot combustion gas stream prior to the point at which the combustion gas stream has reached maximum velocity is observed to  thereby  produce  carbon  blacks  having  wider aggregate  size  distribution.    The  process  of  the invention enables one to produce carbon blacks having wider aggregate size distribution.
