Patent number: 6575806Abstract: A balloon locking cup and securing system includes a cup having a latch interposed between a funnel shaped cup portion and a tube extension. The balloon cup is placed over a reciprocating needle hook rod in a securing system. The tail of the balloon is received by a hook at the end of the hook rod and a first pneumatic cylinder is actuated to pull the needle hook rod in such a manner as to pull the balloon into nesting engagement with the balloon cup. At the end of travel of the first pneumatic cylinder, a second pneumatic cylinder is automatically actuated, causing a knife blade to separate the end of the balloon tail just beneath the tubular member of the balloon cup assembly. The drawing of the balloon into the cup assembly actuates the latch which engages the balloon tail near the neck of the balloon and secures the balloon in the cup assembly.Type: GrantFiled: March 13, 2002Date of Patent: June 10, 2003Assignee: Premium Balloon Accessories, Inc.Inventors: David C. Nelson, John J. Andrisin, Martin A. Meluch

Patent number: 5199847Abstract: A balloon inflator utilizes a bypass motor such that the inflation or working air is separate from the motor cooling air. The intake for the motor cooling and inflation air is separated from exhaust vents to limit any recirculation of the air, assuring that the inflation air be maintained as cool as possible. An impaler is maintained in an involute to achieve the requisiting inflation pressure. A free floating inflation nozzle is maintained within a collar and is adapted for engagement with an output of the involute when inflation activity is desired; otherwise the nozzle is disengaged from the involute allowing the air from the involute to otherwise be exhausted. The motor driving the impaler is selectively interconnected with a half wave rectifier for speed selectability.Type: GrantFiled: February 3, 1992Date of Patent: April 6, 1993Assignee: Premium Balloon AccessoriesInventors: David C. Nelson, William E. Bartasevich, Robert L. Waldo, Wesley A. Schroeder

Patent number: 4921402Abstract: A valving mechanism for a balloon inflator is presented. The valving mechanism is attached to an inflator comprising a fan driven by a through-flow motor. A piston, received within a cylinder, has two bores passing therethrough, the first bore communicating with atmosphere, and the second bore communicating with a nozzle adapted for receipt of a balloon neck. When the balloon is placed on the nozzle and the piston is urged against a spring, an airstream passes through the second bore to inflate the balloon. When the balloon is removed, a spring urges the piston to a position in which the airstream passes through the first bore to atmosphere reducing the load on the motor and allowing the motor to run cooler.Type: GrantFiled: May 1, 1989Date of Patent: May 1, 1990Assignee: David C.

Patent number: 4906170Abstract: An apparatus is presented for printing material on an extruded plastic tubing. An extruder forms the plastic tubing of the desired diameter and thickness. The tubing is then drawn through a cooling bath by a pulling mechanism, and cut into desired lengths. The tubing may be dried after the cooling process, and an ink jet printer is utilized to print on the tubing as it is being drawn to be cut. A computer controls the printing process in correlation with the tubing cutter to provide a print signal to the printer in accordance with the desired lengths of tubing. The print heads of the printer are also three-dimensionally adjustable so as to center the printed material on the desired size and length of tubing to be cut.Type: GrantFiled: February 16, 1988Date of Patent: March 6, 1990Assignee: Cello-O-CoreInventors: David C. Nelson, Michael J. Fresh, Thomas B. Allen

Patent number: 4895545Abstract: An integral balloon cup holder and stick is provided in which the cup has a longitudinal slit passing through the sidewall thereof from an open end of the cup to a closed end thereof which is attached to a shaft. The slot terminates at the stick. The cup has a neck and shoulder portion with a bottom of the neck being angled to direct a balloon neck outwardly through the slot for secured engagement about the neck prior to reinsertion of the balloon neck through the slot for maintenance within the cup and below a balloon nested therein.Type: GrantFiled: June 27, 1988Date of Patent: January 23, 1990Inventor: David C.

Patent number: 4798554Abstract: Disclosed are one-piece, funnel shaped balloon holders, comprising a conical cup and a hollow cylindrical stem. A longitudinal slit extends the entire length of the balloon holder, from the upper edge of the cup to the lower end of the stem, to permit insertion of the neck of a balloon into the holder. A short slot at the bottom of the stem anchors the balloon tail. In a first embodiment (FIGS. 1-3), a balloon stick is inserted into the hollow stem. In a second embodiment (FIGS. 4-8) the stem is inserted into one end of a hollow balloon stick. The stem in this embodiment is of such shape as to provide space between the stem and the balloon stick for a portion of the balloon neck so that the entire balloon neck is concealed.Type: GrantFiled: April 19, 1988Date of Patent: January 17, 1989Inventors: David C. Nelson, Michael J. Fresh, Herbert Mueller

Patent number: 4732392Abstract: An apparatus for playing a plurality of bingo cards, simultaneously. Sets of numbers, stored on a plurality of bingo cards, are read by a plurality of card readers. Each number called, during the play of bingo, is input manually into storage. A comparison of each called number with the previously stored sets of numbers results in a match or no match. If a match exists, an LED located below the card number lights to indicate the number on the bingo card(s) which matches the number called.Type: GrantFiled: August 28, 1985Date of Patent: March 22, 1988Assignee: Robert EdwardsInventors: Robert G.
