Patent CA-2439013-A1 (CA)
Title: Method, apparatus and article for verifying card games, such as playing card distribution
Inventor: SOLTYS RICHARD
IPC: A63F9/24
Filed: 2002-02-21
Abstract: One or more actual hands of playing cards are verified against respective expected hands of playing cards, to determine whether the playing cards actually dealt correspond to the playing cards that should have been dealt based on a starting sequence of playing card values. The starting sequence of playing card values can be computationally pseudo-randomly generated, where playing cards will be ordered, for example by printing or sorting, according to the sequence for distribution to the player and/or dealer. The starting sequence of playing card values can be determined by reading identifiers from a number of playing cards prior to dealing.

Title: New and improved railroad tie and method for making same
Inventor: SULLIVAN HENRY W
IPC: B29C48/06
Filed: 2002-03-05
Abstract: Thermoplastic polymers, rubbery polymeric components and reinforcing fillers are mixed and heated to a range of 380 ~F to 440 ~F. The resulting mixture is then fed into a Banbury mixer(s10), with the resulting mixture fed into a diverter(s16) feeding two molds(s17). The velocity of the piston of each mold being filled is controlled to thereby control the density of the molded product along its length. As each mold is filled, it is deposited in a cool water bath (50 ~F-60 ~F)(s20) while the next mold is being filled. The molds are sequentially transferred to an air cooling rack to complete the process. A  texture, generally comprising indentations perpendicular to the longitudinal axis on the molded object, provides a frictional surface between the railway crosstie and the ballast beneath the corsstie.
