Title: Process and apparatus for producing isobutylene polymers
Inventor: BERLIN ALEXANDR ALEXANDROVICH
IPC: C08F10/10
Filed: 1985-10-04
Abstract: The present invention relates to the chemistry of polymers and, more particularly, to a process and an apparatus for producing isobutylene polymers. The process comprises supplying a stream of an isobutylene-containing feedstock into the reaction zone of a reactor at an angle of 30 to 120 DEG  to the axis of a flow of the reaction mass simultaneously with admission of a stream of a solution of an acid catalyst in at least two points; the catalyst stream direction constituting an angle of from 30 to 90 DEG  to the direction of the feedstock stream. The next step of the process comprises polymerization of the feedstock in the reaction mass flow turbulently moving along the reactor at a speed of from 0.3 to 15 m/s. The apparatus for implementation of this process comprises a reactor-tube (1) with an inlet socket pipe for the catalyst supply (2) positioned on the end face of the tube (1) and directed inwardly and provided with at least two openings (6) on its cylindrical surface with their axes forming an angle of from 30 to 90 DEG  to the axis of the tube (1).

Title: Electronic component placement
Inventor: HAWKSWELL VICTOR THOMAS
IPC: H05K13/04
Filed: 1985-11-09
Abstract: Components such as 'chips' are engaged mechanically by a placement tool 30 which places them in the desired position on a substrate. Radiation from a source 64, 68 casts shadows of a component (C) carried on a tool 30 on detector arrays 66, 70 to determine the position of the component (C) relative to an axis T. Consequent on the determined position the component is placed at a predetermined position on a substrate (S), conveniently mounted on an X-Y table (12). The system first orients the component (C) by rotation of the tool 30, then corrects a programmed placement position of the X-Y table according to the displacement of the component (C) from the axis T, avoiding physical contact between the component and mechanical orienting means, and permitting use of a rubber (or other cushioned) tip to the tool 30, militating against damage to the component. <IMAGE>

Title: Process and apparatus for removing PCB's from electrical apparatus
Inventor: FOWLER DAVID E
IPC: B01D11/04
Filed: 1985-11-13
Abstract: A process for removing polychlorinated biphenyls from electrical apparatus, particularly transformers, to achieve concentration levels of 50ppm or less as required by the EPA uses a dielectric fluid having a relatively low boiling point as compared to polychlorinated biphenyls and other contaminants and in which PCB's are soluble. There is an external cooling loop through which the dielectric fluid is circulated maintaining the temperature and pressure of the transformer within its design limits. There is an external distillation loop where the liquid removed from the transformer is heated to boiling point of the selected dielectric fluid thereby vaporizing the dielectric fluid and leaving the polychlorinated biphenyls in liquid phase in the distillation vessel. The dielectric fluid vapor is then condensed and returned to solubilize remaining PCB's in the transformer.
