Title: Mounting bushing for an overload protector
Inventor: BUTCHER JAMES A
IPC: H02K11/00
Filed: 1990-12-13
Abstract: A bushing for mounting an overload protector within an opening in a motor shell comprises segments adapted to be coaxially positioned around a portion of the overload protector. Mating features formed on the segments and protector restrict movement of the protector relative to the segments. Grooves formed on the segments secure the segments within the opening and restricts movement of the bushing and protector assembly relative to the structure. The bushing preferably comprises a pair of generally symmetrical segments connected together by an integrally formed hinge. The one-piece bushing is molded from a thermoplastic material, such as nylon. In one embodiment, the features which restrict axial movements of the overload protector relative to the segments era mating threads formed on a portion of the internal surfaces of the segments, and on opposing portions of the external surface of the protector. An additional structure is formed on the exterior surface of the segments to prevent rotational movement of the protector relative to the bushing. In an alternative embodiment, a structures is formed on and extends from the segments, and at least partially surrounds the overload protector to secure the protector against opposing portions of the bushing. A portion of each of the segments extends outwardly from the exterior surface of the motor shall so as to shield an exposed and portion of the overload protector from damage. A gasket may be mounted to this portion of the bushing to prefect the overload assembly from dust and contamination.

Title: The diastereoselective preparation of phosphinate esters
Inventor: SEDERGRAN THOMAS C
IPC: C07F9/572
Filed: 1990-12-20
Abstract: An increase in the diastereoselectivity resulting from the reaction of a phosphinic acid ester of the formula <CHEM>  with the halo ester of the formula <CHEM> is achieved by carrying out the reaction in the presence of 4-methylmorpholine, diazabicyclooctane, quinuclidine, 1-methylpyrolidine, or cinchonidine. After removal of the R3 protecting group and fractional crystallization, the resulting desired diastereomeric pair can be resolved, and the desired isomer can be coupled to 4-substituted L-proline to give compounds possessing angiotensin converting enzyme inhibition activity. In particular, the process is useful in producing the antihypertensive agent fosinopril sodium in increased yields.

Title: Apparatus for utilizing post consumer (recycled) polyester resin containing contaminents
Inventor: COLLETTE WAYNE N
IPC: B29C45/63
Filed: 1991-01-02
Abstract: ABSTRACT OF THE DISCLOSURE      This relates to an apparatus for utilizing post consumer polyester resin such as PET (PCPET) which is provided in the flake state and which will contain certain contaminents.  A screen pack is utilized to remove the solid contaminents from the molten thermoplastic resin top eliminate the more costly prior extrusion of the PCPET through a screen pack and the chopping thereof into pellets.  Since the pressure of the molten polyester resin passing through the screen pack is much less than that required for the injection molding of a preform, the molten resin passing through the screen pack is first directed into a pot by way of a rotary valve which is then set to permit the delivery of the molten resin from the pot into the mold cavity. Suitable apparatus is also provided for blending PCPET with virgin PET (VPET) to first provide a desire blend of PCPET and VPET, after which the IV of this blend is increased by the selected addition of additional VPET.

Filed: 1991-02-06
Abstract: Abstract of the Disclosure The  present  application  discloses  a  process  for  the production of agglomerates of peroxides that are solid at room temperature and which decompose rapidly when heated to their melting point.   The process comprises agitating an aqueous suspension comprising a solid first peroxide which rapidly decom-poses when heated to its melting point and a solid second peroxide which does not rapidly decompose when heated to its melting point and has a melting point which is substantially lower than the temperature at which said first peroxide rapidly decomposes, at a temperature sufficient to at least partially melt said second peroxide and below the decomposition temperature of said first peroxide to produce agglomerates comprised of said first and second peroxides; cooling with continued agitation the aqueous suspension having agglomerates to a temperature at which said second peroxide turns solid; and isolating the agglomerates. Also disclosed is a process such as that described above wherein a solvent immiscible with water is employed to aid the agglom-eration process.  The agglomerated peroxides are particularly useful in the polymerization of vinyl chloride monomers and the curing of unsaturated polyester resins.

Title: Impact resistent compositions comprising polyarylene sulfide and polysiloxane graft polymer
Inventor: YAMAMOTO NAOKI
IPC: C08K5/5435
Filed: 1991-10-08
Abstract: A polyarylene sulfide resin composition obtained by melt-mixing a composition consisting essentially of 60 to 99 parts by weight of a polyarylene sulfide resin (component A), 1 to 40 parts by weight of a polyorgano-siloxane graft copolymer (component B) obtained by graft-polymerizing one or more kinds of vinyl monomer onto a compound rubber of 0.08 to 0.6 µm in average particle size consisting of a polyorganosiloxane rubber component and a polyalkyl (meth)acrylate rubber component and having such a structure that 1 to 99 wt.% of the polyorgano-siloxane rubber component and 1 to 99 wt.% of the polyalkyl (meth)acrylate rubber component have been inseparably united with each other, the total amount of the components A and B being 100 parts by weight, and an organic silane compound having an epoxy group (component C) of 0.01 to 10 parts by weight based on 100 parts by weight of the total amount of the components A and B. The composition of the present invention, whether it contains a reinforcing filler or not, is excellent in the compatibility between the polyarylene sulfide resin and polyorganosiloxane graft copolymer. If this composition is extrusion-molded or injection-molded under the common molding conditions, it keeps its original dispersed and mixed condition without showing a phase separation.      Consequently, this composition has excellent performances described below: Impact strength also is given to the polyarylene sulfide resin without largely injuring the excellent properties inherent in the resin; when this composition contains no reinforcing filler, there is no development of a pearly lustre which is easy to appear when the polyarylene sulfide resin and other resin component are mixed; and even when this composition contains a reinforcing filler, a molded product obtained therefrom is excellent in surface smoothness.

Title: Nozzle mountings
Inventor: MARKS KIPLEY R
IPC: B05B15/06
Filed: 1991-11-20
Abstract: A nozzle mounting having a body with an air passageway and a water passageway therein and a nozzle member with outer walls of spherical form. The outer walls of the nozzle member are retained in sealing contact with the body by a retainer which also permits manipulative rocking movement of the nozzle to direct a flow of combined water and air which exits the nozzle in use.The nozzle has a water entry and an air entry so that when water under pressure is supplied to the nozzle, the water enters the water entry and air from the air entry is entrained in the water within the nozzle and a mixture of air and water exits the nozzle. Since air is entrained in the water within the nozzle, the nozzle retains its position. A sealing sleeve provided within the body adjacentthe nozzle member has means to control the flow of water and air through the nozzle member in response to rotation of the sleeve relative to the body. The sleeve is rotated by an outer retaining member which retains the nozzle member in the body.
