US Patent:

8111497, Feb 7, 2012

Filed:

Aug 12, 2009

Appl. No.:

12/462982

Inventors:

Michael J. Blackburn - Morris IL, US

International Classification:

H05F 3/00

US Classification:

361215

Abstract:

A device for electrically discharging samples of an electrically non-conductive liquid includes an electrically conductive outer member , an electrically conductive inner member disposed within the outer member , an electrically conductive rod with upper and lower plugs and secured thereto to maintain a non-conductive fluid in the device , non-conductive handles and secured to the outer and inner members and , and an electrically conductive ground cable detachably secured to the rod to ultimately remove or reduce static charge in the electrically non-conductive liquid via the liquid engaging the outer member , inner member and rod , which are electrically grounded via the cable.

International Classification:

G01N 112

US Classification:

7386463

Abstract:

A fluid sampling device includes a tube, one end of which is adapted to be placed into a fluid medium. An actuator on the opposite end moves a rod along the longitudinal axis of the tube to bring a stopper into and out of sealing engagement with the fluid receiving end of the tube. With the fluid receiving end open, it is placed beneath the level of the fluid. The pressure of the fluid causes fluid to enter the tube to the level of the surrounding fluid. Then the stopper is closed, thus sealing the fluid sample within the tube, so that the sample may be removed. A stopper for sealing the upper end of the tube may also be provided, with the actuator moving both the upper and lower stoppers. The tube is formed of polypropylene extruded to 0. 050 inches. +-.

International Classification:

A63B 6308

US Classification:

273 15R

Abstract:

An apparatus for mounting a basketball rim to a glass basketball backboard to prevent a basketball rim from being torn from and thereby shattering the backboard. A small portion of a glass backboard normally supporting a basketball rim, is removed and replaced with a rim mounting plate. The rim mounting plate is joined between two horizontal support tubes that connect to a support frame that attaches to the perimeter of the glass backboard. A support bracket assembly is connected to both the rim mounting plate and the glass backboard to secure the assembled rim and backboard to a support pole.

International Classification:

A63B 6308

US Classification:

273 15R

Abstract:

A force limiting adjustable basketball goal includes a support member and counter-weight to rotate a basketball goal around a support pole to vary the rim elevation above a playing surface. An anchor chain secured to the pole and counter-weight includes a safety link that breaks when a pre-selected force is exerted upon the rim by a player dunking a basketball or hanging on the rim. When the safety link breaks, the basketball goal falls slowly to the playing surface, thereby requiring the replacement of the safety link before play is allowed to resume.
