Patent number: 5609342Abstract: This invention relates to a lubricating film type gas seal having a stationary sealing ring (stator) with a radially extending sealing face and a rotating mating seal component (mating rotor) with a radially extending sealing face. The present seal has a reduced number of components and is greatly simplified from working seals described in prior art. The mating rotor is deliberately flexible, and hence it may distort (tilt) throughout an angular range during hydrostatic and hydrodynamic operation and is dependent on rotational speed, pressure, temperature and is also a function of its material and geometric properties. The stationary ring sealing face complies to and follows the angular distortion (tilting) of the mating rotor sealing face in a converging or diverging manner throughout the hydrostatic and hydrodynamic operational range. The flexibility of the stator is a function of its geometric and material properties. Mating rotor and stator flexibility is preferably matched (e.g.Type: GrantFiled: July 11, 1994Date of Patent: March 11, 1997Assignee: Revolve Technologies, Inc.Inventors: Robert A.

Patent number: 5543461Abstract: High impact polystyrene (HIPS) and other impact modified styrenic polymers such as ABS and MBS tend to suffer from environmental stress cracking. On extended exposure to oily or fatty substances the plastic tends to craze, then crack and finally break. Unfortunately, a number of applications for impact modified polymers is in areas where there is a high potential to contact with oily or fatty substances. The environmental stress crack resistance (ESCR) of impact modified styrenic polymers may be increased by increasing the particle size of the impact modifier and including a low molecular weight polybutene.Type: GrantFiled: March 9, 1994Date of Patent: August 6, 1996Assignee: Novacor Chemicals (International) SAInventors: Brenda C.

Patent number: 5514750Abstract: A post inversion metastable syrup comprising a continuous or co-continuous rubber like composite phase and a discontinuous or co-continuous resin phase may be particulated by the application of a shear field to yield a stable syrup comprising a dispersed rubber-like composite phase and a continuous resin phase. The application of a uniform shear field to the post inversion metastable syrup is particularly desirable since it results in a high degree of control over the size and distribution of the dispersed rubber-like composite phase. As a result it is possible to optimize the particle size distribution in an impact modified thermoplastic and obtain better or a better balance of properties. The present invention also provides in cooperating arrangement reactors or devices to produce a post inversion metastable syrup, a device to subject the roetastable syrup to a shear field and a polymerization plant.Type: GrantFiled: April 17, 1995Date of Patent: May 7, 1996Assignee: Novacor Chemicals (International) S.A.Inventors: James E.
