Title: Method for preparing hollow latexes
Inventor: MCDONALD CHARLES J
IPC: C08J9/20
Filed: 1990-09-18
Abstract: The present invention provides for a process for preparing hollow polymer latexes. A first charge of a organic phase is introduced to an aqueous phase. The first charge of the organic phase comprises monomer, which is virtually insoluble in the aqueous phase, and an inert-nonpolymerizable hydrocarbon. The polymer formed from polymerizing the monomer is virtually insoluble in the hydrocarbon, the hydrocarbon is virtually insoluble in the aqueous phase and the monomer is miscible with the hydrocarbon. The monomer is polymerized to produce a low molecular weight polymer which phase separates from the organic phase and concentrates at the surface of the organic phase forming a low molecular weight polymer phase. A second charge of the organic phase is then introduced to the aqueous phase when the low molecular weight polymer reaches a conversion of monomer to polymer of equal to or less than 80 percent, wherein the second charge of the organic phase comprises a crosslinking monomer and wherein the crosslinking monomer is imbibed in the low molecular weight polymer phase. Further polymerization produces a hollow polymer latex particle.

Title: Hollow shell deflection reading system
Inventor: GEBHART WALTER M
IPC: G08C21/00
Filed: 1990-10-25
Abstract: ABSTRACT OF THE DISCLOSURE A direct reading ovality sensing and recording system for attachment to the outer surface of the steel shell of a kiln or like rotary processing equipment, utilizes a so-called dial  (or depth) testing indicator (DTI) mounted upon a short chordal bridge.  The instrument directly measures fluctuations in the distance between the surface of the kiln shell and the centre of the bridge.  The digital electronic output from the DTI is recorded in a data logger, during the rotation of the kiln, under normal working conditions.  The primary use of the system  is  to  accurately  measure  the  actual  conditions  of flexing of the steel  shell,  with a view to optimizing the service life of the refractory lining carried in the interior of the kiln.  Additionally,  a qualitative indication of kiln alignment  at  the  respective  pier  supports  can  also  be ascertained.   In the case of high temperature kilns, where a high thermal gradient acting on the structure of the chordal bridge may produce  transient deformation thereof,  so as to affect the DTI readings,  the system facilitates quantitative evaluation of such thermal deformation,  so that the readings may be correspondingly compensated.
