Abstract:
A process for stabilising the viscosity of an amino-functional siloxane polymer comprises adding a dialkoxydialkylsilane to the amino-functional siloxane polymer or to the reagents from which the amino-functional siloxane polymer is produced.

Abstract:
A method is provided whereby airplanes or any device with the functionality and usefulness of an airplane may be controlled without the use of any traditional effectors, such as flaps, rudders, ailerons, spoilers, and all like hinged, moveable airfoils attached to a wing or a fuselage. The means of controlling such airplanes while in flight will be by controlling the laminar air flow over all lifting surfaces so as to vary the amount and quality of the lift provided. All lifting surfaces on the airplane will be divided into dozens, hundreds, or thousands of small zones, each of which can be readily controlled by a central flight computer and each of which is capable of modifying its immediate airflow condition, whether that be laminar flow or some particular degree and variety of local eddy current. Summing over all the inputs of conditions above the multitude of zones, the central flight computer will possess algorithms and programs suitable to effect any desired change in attitude, altitude, orientation, and course of the airplane that is desired.
Abstract:
A method of launching space vehicles by towing them aloft, then twirling them around a large transport aircraft (40) at the center of a formation (AA) of other tow aircraft (28, 34) and other devices of the invention. A lengthy, semi-rigid tow pipeline (14) serves as a conduit for the transfer of fuels and oxidizers, as the tow cable, and as an energy storage device that reflexes efficiently when it is flexed. The flexing of tow pipeline (14) is caused by a parachute (22) acting in conjunction with all the aircraft making the tighest turn they are capable of doing. Tow aircraft in certain arrays (28) are joined to tow pipeline (14) by sliding trollies (26) that also host canard rotor wings for the aerodynamic support of the main tube (12). The tow trollies (26) aid the sliding tow aircraft arrays (28) in gaining mechanical advantage to accelerate the space vehicle. The space vehicle may also burn its own motors for a longer-than-usual time as it gains in angular velocity because its fuels are replenished by a pipeline that automatically increases the pressure and volume of fuel flow as the angular acceleration increases. The tow pipeline (14) features a micro-hole laminar lift foil (50) on the top surface of the wing and on the bottom. By balancing the vacuum level in the plurality of chamber underneath the plurality of lift foil 50, the pilot or autopilot has an effective way to control the flight characteristics of the tow pipeline (14). In some embodiments the micro-hole laminar lift foil (50) on the top and bottom will made of transparent hollow wire segments or other material so arranged as to pass ambient light through to photo-voltaic cells below that convert sunlight to electrical energy.
