Appl. No.:

6/218826

Inventors:

Ray Kendall - Fort Worth TX

Assignee:

Dynalectron Corporation - McLean VA

International Classification:

B60B 3306

US Classification:

280 4317

Abstract:

A retractable caster assembly for permanent attachment to a framework. The caster assembly, when retracted, allows the framework to rest on a surface in a first stable position and when extended, the assembly raises the framework above the surface in a second stable position. The caster assembly comprises a caster, a caster carrying structure, a structure for pivotably mounting the caster carrying structure to the framework and a lever pivotably mounted to the framework for engagement with the caster carrying structure to lower the caster into engagement with the surface in one stable position and raise the center so the lower periphery of the caster is above the lower surface of the framework in another stable position of the assembly.

Abstract:

A fluid collection, dispensing and measurement device for use in connection with a blood container, for example, and flexible tubing leading thereto. A hollow balance bar, with mobile spherical weights disposed therein is provided and rapid, forceful cut off of the blood flow through the flexible tubing is achieved when the moment created by the filling blood container, accentuated by the motion of the spherical weights, overcomes the moment produced by a preset adjustable counter weight. An adjustable clamping apparatus allows the fluid collection device to be affixed to a stationary object and subsequently adjusted to a level plane to insure accuracy of measurement. A simple modification of the device allows it to be used as a fluid dispensing device. A full container of fluid can be hung on the modified device and a measured quantity of fluid can be dispensed with cut off being achieved as described above.
