Abstract: An apparatus for practicing putting at home. Such apparatus comprises a foldable enclosure member being formed of two substantially identical portions, each of the substantially identical portions having a base member forming a floor for the foldable enclosure. A first portion having a back end, a left side and a right side engageable with such base member, a second portion having only a left side and a right side engageable with the base member. A preselected material is disposed on top of the base member for use as a putting surface. A predetermined number of holes are disposed in such preselected material and such base member and are positioned at preselected locations. A hinge mechanism is engageable with an underside closely adjacent abutting edges of each of the substantially identical portions of said foldable enclosure for folding said apparatus.

Abstract: The present invention provides an electrochemical cell of either a primary or a secondary chemistry housed in a casing having opposed major side walls of a contoured shape.

Abstract: An alkali metal/solid cathode electrochemical cell, particularly a Li/CFx cell, having an electrolyte-to-cathode (E/C) weight ratio of about 0.938 to about 0.73, and an anode-to-cathode (A/C) capacity ratio of about 1.03, is described. This provides the cell with an improvement in terms of delivered capacity of about 6% to about 15% under a 1 kohm discharge load, and of about 2% to about 5% under a 2 kohm load in comparison to prior art Li/CFx cells. Fabricating the cathode electrode at such high pressures was not previously thought possible.
