Abstract: ABSTRACT OF THE DISCLOSURE The impact resistance of resin compositions consisting of a thermoplastic polymer, particularly a homopolymer or copolymer of vinyl chloride can be improved by an impact additive of the graft copolymer type.  The graft copolymer impact additive consists of a backbone composed of a statistical copolymer of butadiene or isoprene, an alkyl acrylate of a C2 to C12 alkyl, and optionally a polyfunctional cross-linking agent, onto which are grafted the chains of a statistical copolymer of an alkyl methacrylate of a C1 to C4 alkyl, particularly methyl methacrylate, and an alkyl acrylate of a C1 to C8 alkyl, particularly ethyl acrylate.  The backbone of the graft copolymer impact addi-tive comprises 0.5 - 35% by weight butadiene or isoprene, and up to 10 mole % of the cross-linking agent, while the graft chains of the graft copolymer comprise 5 to 50 mole % of the alkyl acrylate of a C1 to C8 alkyl, and the weight ratio between the grafted chains and the backbone can range from 10 to 200%.  The resin compositions are particularly useful to improve impact strength at low temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE      Novel rotary processors which involve a devolatilizing stage including a rotatable element carrying a plurality of annular channels and a stationary element providing a coaxial closure surface operationally arranged with the channels to provide enclosed processing passages.  Each passage of the devolatilizing stage includes inlet means, outlet means and a channel blocking member all associated with the stationary element and arranged and adapted so that material fed to the inlet can be carried forward by the rotatable channel walls to the blocking member for discharge from the passage.  The passages are interconnected by material transfer grooves formed in the closure surface.    The rotary processors of this invention include a novel vacuum system to evacuate the devolatilizing stage.  A large manifold completely encloses a relatively large opening through the stationary element and communicates with a vacuum source through a relatively large vacuum port to simultaneously evacuate the passages of the devolatilizing stage at low vapor velocities.  The novel vacuum system also includes means to effectively prevent material buildup at least in the region of the opening through the stationary element and the manifold.

Abstract: ABSTRACT OF DISCLOSURE     A  process  for  high  hydroconversion  of  heavy  liquid hydrocarbons,  such as petroleum resid feedstocks containing at least about 25 V % material  boiling above about 975°F+, using multi-stage catalytic reactions at elevated temperature and pressure to  produce  increased yields  of lower boiling hydrocarbon liquids and gas.   In the process, the feedstock is fed in liquid phase with hydrogen at elevated temperature and  pressure  conditions  into  a  staged  catalytic  reactor system,  preferably containing ebullated catalyst beds.  from which  a  vacuum  bottoms  fraction  having  a  nominal  boiling point above about 800°F is recycled to the last-stage reactor rather than to the first-stage, to improve conversion of the 975°F+  fraction  to  lower  boiling  liquid  products.    If desired, three stages of catalytic reaction can be used with the vacuum bottoms material  fraction being recycled to the third stage reactor.

Abstract: ABSTRACT      A weight actuated tubing valve is shown which is incorporated  within  a  tubing  sub,  installed within  a string of tubing extending from the well surface within a well  bore.    The  tubing  valve   includes  an  outer cylindrical sidewall and an inner mandrel which is spaced apart from the sidewall to define an annular space.  The outer sidewall and inner mandrel are each provided with one or more openings for communicating the interior bore of the tubing string with the well annulus.  A sliding sleeve is located within the annular space and is movable between a first position which closes off the mandrel opening from the annular space to a second position in which the mandrel opening communicates with the annular space, and through the sidewall opening with the exterior of the tubing string.  A fluid chamber initially contains a  fluid  for  supporting  the  sliding  valve  within  the annular space  in  the  first  position.   A  hollow  pin initially contains the fluid within the annular space but is sheared by dropping a weight within the tubing string, whereby the support fluid is released from the annular space to allow the sleeve to move to the second, open position.

Abstract: In an aerobic process for waste water (effluent) purification with intermittent batch feed of the waste water to the activated sludge tank from which the treated waste water is discharged continuously, the nitrate content of the waste water is simultaneously reduced by the aeration of the activated sludge tank, commencing with the flow of the waste water to the tank, being restricted to values corresponding to </= 0.5 mg/1 of dissolved oxygen, or in particular turned off, until the nitrate content in the tank has fallen below 5 mg/1 or, in particular, below l mg/1. In such treatment of communal waste waters, an approximately 1 hour cycle time is advantageous and the aeration, commencing with the rapid input of the waste water charge, is turned off for about 5 minutes. Suitable feed batches are </= 30% and, in particular, between about 5 and 20% of the tank contents. In this process, the nitrate content is reduced during the phase with oxygen restriction, while in the subsequent phase (over longer periods of time), the ammonium carried in with the waste water feed is converted into nitrate, it being advantageous to provide for an adequate nitric bacteria population in the tank.
