Title: Method and apparatus for testing golf putting skills
Inventor: GREEN PAUL
IPC: A63B57/00
Filed: 1994-02-18
Abstract: A method of testing golf putting skills is described. Firstly, set out a test putting surface having at least one target representing a golf hole.   The at least one target includes a central zone with at least one concentric zone surrounding the central zone.   Numeric scoring values are assigned to the central zone and the concentric zones.  The scoring values descend as the concentric zones get farther from the central zone.  Secondly, establish at least one shooting position a selected distance from the at least one target. Thirdly,  test a statistically valid sample of golfers of differing abilities.  Each golfer is tested in a consistent manner with at least 10 putts from the at least one shooting position.   Data is compiled on the gross score obtained by golfers of differing abilities by adding the numeric scoring values attained by each golfer for each of the at least 10 putts.    Fourthly, test an individual golfer in a manner consistent with the manner in which the statistically valid sample of golfers was tested with at least 10 putts from the at least one shooting position. Fifthly, compare the gross score  attained  by  the  individual  golfer  as  against  the statistically valid sample of golfers to achieve a ranking, termed a putting handicap.  An apparatus best suited for use with the described method is also described.

Title: Improved process for methyl alcohol
Inventor: STAUFFER JOHN E
IPC: B01J27/06
Filed: 1992-12-04
Abstract: An improved method of producing methyl alcohol (methanol) from methane is provided using two reaction steps operated in tandem. In the first reaction step two chemical reactions occur simultaneously: a) perchloroethylene (CCl2CCl2) is oxychlorinated with hydrogen chloride and oxygen to obtain hexachlorethane (CCl3CCl3) and water, and b) methyl chloride (CH3Cl) is hydrolyzed with water to give methyl alcohol and hydrogen chloride. In the second reaction step methane is chlorinated with hexachlorethane to produce methyl chloride, hydrogen chloride and perchloroethylene.  By recycling the methyl chloride, hydrogen chloride, and regenerated perchloroethylene produced in the second step to the first step the process can be operated in a balanced mode whereby the internal consumption of hydrogen chloride is equal to its formation.

Title: Digital signature method and key agreement method
Inventor: RUEPPEL RAINER A
IPC: G06F7/72
Filed: 1994-08-16
Abstract: A digital signature method based on the discrete logarithm problem is provided that allows message recovery. The message x is transformed according to the rule a = x g -r mod p, where r is a secret value generated by the signer. A value y is then calculated according to the rule y = r + s e mod q, where y is the signer's secret key. The signature of x consists of the pair (e,y). The verifier recovers the message x according to the rule x a g y k e mod p, where k is the signer's public key. The validation of x can be based on some redundancy contained in x. Alternatively, a conventional verification equation can be constructed by using the signature method together with a hash function H. In addition, a key agreement method based on the signature method is provided which establishes with a single transmission pass a shared secret key K between two parties A and B in an authenticated fashion.
