Title: Golf ball core compositions
Inventor: NESBITT R DENNIS
IPC: C08K3/22
Filed: 1992-10-21
Granted: 2002-01-08
Abstract: The present invention is directed to improved polybutadiene compositions suitable for use in molded golf ball core construction. The improved polybutadiene compositions are composed of polypropylene powder resins which have the effect of increasing the hardness of the resulting molded cores without increasing the weight upon daring, thereby allowing for a reduction in the amount of crosslinking agents utilized and increasing the amount of fillers incorporated therein. The addition of the polypropylene powder resins to the core compositions lowers the cost of the molded core, while maintaining the proper weight and compression. The present invention is also directed to golf balls produced utilizing the improved core compositions.      Furthermore, the invention is directed to a method for reducing the amount of crosslinking agents utilized to formulate a core composition through the incorporation of polypropylene powder resins. In addition, a method for decreasing the amount of crosslinking agents and increasing the amount of mineral fillers included in a core composition through the incorporation of polypropylene powder resins is also disclosed.

Abstract: An apparatus and method for determining the amount of nitrogen in an object. A support means is provided for supporting the object, and at least one gamma ray beam is disposed on one side of the support for producing a beam of about 9.2 MeV gamma rays and in sufficient intensity to cause measurable resonant absorption by 14N in the nitrogenous compounds. A directing device is disposed between the gamma ray beam and the support for directing the gamma ray beam to the support at a predetermined angle, such that the gamma ray beam forms a path which encounters at least a portion of the object when disposed on the support. An array of gamma ray detectors are disposed on an opposite side of the support for detecting gamma rays of about 9.2 MeV transmitted through the object at both resonant and non-resonant angles. A computation device computes the difference in the amount of transmitted gamma rays detected by the detectors at the resonant angles and non-resonant angles, and the difference is related to the amount of nitrogenous compounds in the object.

Abstract: A tubular arthroscopic sheath having improved irrigating fluid flow characteristics and having a quick coupling socket adapted to quickly connect to and disconnect from an associated arthroscopic tool provided with a mateable, generally cylindrical plug member.  The fluid flow is enhanced by centering projections on the sheath interior and by turbulence minimizing fluid ports. The socket comprises an open ended cylindrical housing provided with a plurality of annularly spaced, cylindrical locking pins slidable within throughbores in the housing wall, the throughbores extending radially from the housing axis and axially skewed with respect thereto.

A pair of slidable coaxial cylindrical actuating members is adapted to engage all the notches and capture the pins.  Moving the slidable actuating members away from the open end of the housing causes the pins to slide radially outwardly in the throughbores.  Allowing a bias means to urge the actuating members toward the open end of the housing causes the pins to slide radially inwardly.

Title: Fraud protection for card transactions
Inventor: PENZIAS ARNO ALLAN
IPC: G06Q20/40
Filed: 1994-01-31
Granted: 1997-04-29
Abstract: The problems of fraud in card transactions can be reduced by, after requiring the person engaged in the card transaction to initially identify himself, such as by supplying a card number, a) requesting, the person to supply as authentication information either 1) a randomly selected piece of prestored information or 2) information derived from a randomly selected piece of prestored information; and b) completing the transaction only if the authentication information requested is correctly supplied. The authentication information requested is described in terms of its nature, i.e., what it represents, so that one can not deduce from the request the correct response without knowing the selected prestored piece of information. Since the authentication information is randomly determined for each card transaction, a thief will rarely, if ever, be able to successfully complete a card transaction simply by supplying, in response to a request, the same piece of authentication information last supplied by the authorized person. Each authorized person already knows theparticular pieces of information that are prestored for him, e.g., birthdate of spouse, year of school graduation, and mother's telephone number. Thus, he need exert noextra effort to remember them. If the pieces of prestored authentication information are various numbers they may be transmitted over a telephone network from a caller to the authorization system using currently available dial pads and DTMF signaling.
