Filed:

Feb 2, 1994

Appl. No.:

8/190362

Inventors:

Aldo Arena - Smithtown NY
Christopher Horan - Huntington NY
Brian Robinson - Bayside NY

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

G05D 2302

US Classification:

236 93R

Abstract:

A compensation device receives an inlet fluid flow and adjusts the pressure at an outlet so as to maintain a constant Reynolds number throughout the operating temperature range of the fluid. This is accomplished by a metering valve device in the nature of a fluted pin which becomes displaced in response to fluid temperature variations. This displacement varies the exposed cross-sectional area of a fluted end of the pin as it becomes seated to a greater or lesser extent in response to temperature variations. This results in corresponding changes in pressure between the inlet and outlet of the device while maintaining a constant Reynolds number. An additional embodiment includes an unfluted pin which becomes seated in a fluted bore located in a removable knurled knob. This allows one to insert various knurled knobs with fluted bores which have geometric configurations particularly adapted for particular fluids. Such a modular approach avoids the necessity of dismantling the device.

Abstract:

The present invention relates to apparel which can be worn during breakdancing as an aid to the dancer in performing the breakdance movements and for distributing impact and torsional loads encountered by the dancer during the breakdance. The breakdance apparel of the present invention in its simplest form is apparel in which those portions of the apparel which contact the support structure have a relatively low coefficient of friction. In a preferred embodiment of the present invention the apparel is provided with resilient regions having an external surface with a relatively low coefficient of friction. In one embodiment the breakdance apparel of the present invention may be in the form of a jacket, jump suit or vest which has been provided with elements having a relatively low coefficient of friction. In another embodiment of the present invention the breakdance apparel is in the form of an accessory designed for placement over those portions of the skeletal frame which may be subject to impact and torsional loads.
