Abstract: Generally speaking, this is a card positioning device which maintains a card such as a greeting card or a postcard in a standing position. The card experiences a destabilizing moment. The card positioning device has a moment resisting section to resist the destabilizing moment and maintain the card in a standing position. The moment resisting section connects to the origin end of the longitudinal fold of the card and extends along the card edges from the origin to reinforce the card edges. The moment resisting section has a foot which has a heel and toe to resist the destabilizing moment. An ornament such as a flag, character or emblem can be attached to the base of the moment resisting section. The ornament, moment resisting section and card, may be inserted into an envelope and mailed to a recipient.

Abstract: An adjustable tree stand for holding a tree trunk to position a tree in a substantially vertical position, the tree stand comprised of a generally cylindrical-shaped base member having a top end and a bottom end, the bottom end adapted to be supported by a floor, a generally dish-shaped member is designed to be received by and supported by the top end of the cylindrical base member, a portion of the dish-shaped member is adapted to swivel in the top end of the cylindrical member.

Abstract: A Pivoting Rod Holder for securing fishing rods in a variety of positions while they are in use is described. A rod holder tube is a component of a pivoting rod holding system, which has as its additional components a base with a plurality of catch indentations, a collar, a retaining plate, and a plunger-operated locking mechanism at the base of the rod holder tube. A rod placed in the rod holder tube can be locked into any position along a 360 degree axis by simply pulling the rod holder tube up till it is parallel with the catch indentations in the base, spinning it into the desired position, and pulling back firmly on it. This pushes the plunger-operated locking mechanism at the base of the rod holder tube into one of the catch indentations in the base, where it is secured. To release, the rod holder tube is pushed on until the plunger-operated locking mechanism is popped out of the catch indentation in the base.

Abstract: Epoxysuccinamide derivatives of the formula (1): wherein R1 is hydrogen, alkyl, alkenyl, alkynyl, aryl, or aralkyl; R2 is alkyl, alkenyl, alkynyl, aryl, or aralkyl; R3 is hydrogen, alkyl, alkenyl, alkynyl, aryl, aralkyl, heterocyclic, or heterocyclic-alkyl; X is —O— or —NR4— (R4 is hydrogen, alkyl, aryl, aralkyl, heterocyclic, or heterocyclic-alkyl); Y1 is OR5, SR6, or NR7R8; and Y2 is hydrogen or alkyl. The compounds are useful as remedies for bone diseases and arthritis.

Abstract: A lawn chair fish fighter 10 for use with a typical aluminum framed folding lawn chair 1 has an elongated hollow member 11 having a half cylindrical segment 15 attached at its fore end which further has a longitudinally disposed reel notch 16 therein. Attached to the aft end of elongated hollow member 11 is butt plate support member 14 which extends radially outward therefrom and has butt plate 13 attached thereto. A chair hook 12 is attached to elongated hollow member 11 slightly aft of center of gravity C. Lawn chair fish fighter 10 holds a fishing rod and reel 2 in a slightly inclined fishing position and further can be pivoted upwardly for the purpose of fighting a fish.

Abstract: A pendulum for suspending a swinging article from a support structure includes an elongated core having longitudinal ends, enlarged tension heads disposed on each of the longitudinal ends and operable to be engaged and supported by the article and the support structure, a plurality of stiff toroidal elements strung on the elongated core, one of the toroidal elements being a first end toroidal element which is spaced from one of the tension heads, another of the toroidal elements being a second toroidal element which is spaced from the other of the tension heads.
