IPC: B65D35/40
Filed: 1990-01-25
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is directed to a metered dispensing cap system for containers such as tubes and the like.  The system has a base element which is attachable to the neck of a squeezeable container and which has a sidewall portion and a top.  The base element has an opening in the top for outflow of a material from a squeezeable container into a meter element.  This base element may be removeably attachable, e.g. by being screwed on, or may be permanently attached, e.g. by being integrally molded with the container. A one way valve is located in the opening of the base element to permit the flow of material from a container through the open-ing while preventing backflow.  The system also includes a meter element which acts like an inverted trap and which has a sidewall portion and a top with an opening in the top for dispensing of the material therefrom.  The sidewall portion of the meter element is slightly larger than and has the same across sectional shape as the sidewall portion of the base element and this sidewall portion of the meter element is higher than and located about and encompasses the sidewall portion of the base element. Further, the meter element is vertically slideable along the sidewall portion of the base element with an upward position for receiving a volume of material in a pre-determined amount when the squeezeable container is squeezed and downward position whereby the opening in the top of the meter element allows for dispensing of the desired amount of fluid when the meter element is pushed down.

Title: Cellular silicon-oxy-carbide glass from foamed silicone resins
Inventor: RENLUND GARY M
IPC: C03C11/00
Filed: 1990-04-19
Abstract: RD-19,110 CELLULAR SILICON-OXY-CARBIDE GLASS    FROM FOAMED SILICONE RESINS                Abstract Cellular glass structures are made by foaming se-lect silicone resins.  A foaming agent is reacted together with the silicone resin to form a foam that carries the resin as a continuous separate phase distributed throughout the foam.  The foaming agent is removed by decomposition, and the remaining silicone resin is crosslinked to retain the foamed structure.  The silicone resin is then heated in a non-oxidizing atmosphere at a temperature that will pyrolize the resin.  During pyrolysis, the resin densifies to form a unique glass composition comprised of silicon, oxygen and carbon, where carbon is chemically bonded to silicon, but there are essentially no chemical bonds between carbon and oxygen.

Abstract: A control computation unit includes a delay element in addition to an integrating element and a proportional element.  The delay time of this delay element is selected, following the time necessary for due settling (namely, the time required for rendering a controlled variable to follow changes in a control variable command), or the time necessary to restore the controlled variable to the control variable command when a controlled object involved has incurred a certain external disturbance.  In case there exist a computation delay time, a dead time, and/or a detection delay time, respectively in the control computation unit, controlled system, and/or a control variable detector, then the delay time is selected equal to one of the computation delay time, dead time, and the detection delay time, or the sum of these times.  Additional provision of the delay element with a delay time equal to the time desired for due settling to the control computation unit results in settling within the time equal to the time desired for due settling the response.
