Title: Preparation of arylene oligomers
Inventor: TOWLE IAN D H
IPC: C07C49/84
Filed: 1987-09-29
Granted: 1993-01-19
Abstract: ABSTRACT     PREPARATION OF ARYLENE OLIGOMERS     Friedel Crafts preparation of arylene ether (especially arylene ether ketone) oligomers with an exceptionally high degree of isomeric purity and freedom from by-products can be achieved by adding to the Lewis acid reaction system a protic controlling agent selected from ROX, water, RCOOX, RSO3X, and ROY, wherein R is organic, X is hydrogen or metal, and Y is metal.    Contrary to conventional expectation, the protic agent does not significantly acylate or alkylate the Friedel Crafts reaction product, and controlling agents of relatively low molecular weight, e.g., benzoic acid, can surprisingly be selected to produce dispersions of the resulting oligomers.

Title: Steering control system
Inventor: MARSDEN HOWARD A
IPC: B62D5/32
Filed: 1988-05-19
Granted: 1991-01-29
Abstract: Abstract of the Disclosure Steering Control System The steering system of some lightweight vehicles are electronically controlled and have a manually operated mechanical control as a backup. Such manual backup control would not be adequate for large earthmoving, construction and industrial type vehicles.  The subject steering system includes an electrically controlled circuit actuated by rotation of a steering wheel for controlling a main pilot operated steering valve as the primary steering control.  A hydraulic control circuit is also actuated by rotation of the steering wheel for controlling the same steering valve as a backup control when the electrically controlled circuit is not active.  The hydraulic steering circuit is disabled when the electrically controlled circuit is activated.  By using the same steering valve as an integral part of both circuits, the complexity and cost of the overall steering control system is reduced.
