Abstract: A bipolar battery assembly having: a) a plurality of electrode plates stacked together to form an electrode plate stack; b) a liquid electrolyte located between each pair of the electrode plates; and c) one or more channels passing transversely through the plurality of electrode plates and the liquid electrolyte; and wherein the one or more channels include one or more seals therein to seal the one or more channels from the liquid electrolyte.

Abstract: Disclosed is a golf ball ejector device for placement within a conventional practice green putting golf cup. The device includes a cylindrical housing constructed and adapted to fit within a conventional golf cup employing a catapult ejector arm recessed into an angular top surface made operational by an actuating switch which is coupled to a drive motor for operation of a timing cam and release of a spring for operation of the catapult ejector arm. The device allows horizontal ejecting of a golf ball when placed beneath the rim of a golf cup.

Abstract: A method for making a multi-stage cementitious material with high-temperature reinforcing fibers 22 in an outer zone and lower-temperature reinforcing fibers 24 in an inner zone.

Abstract: A method for detecting a type of one of plurality of devices attached to a graphics machine, each device being one of at least a first type and a second type. The method includes detecting at a controller the type of device attached to or to be attached to the machine. The controller is capable of preadjusting the device or machine as a function of the detection. A graphics machine includes a controller, a first device connected to the controller, the first device being categorizable as one of at least a first type and a second type, the controller detecting the type of the first device, and a memory accessible by the controller, the memory storing information regarding the first type and the second type.

Abstract: A golf ball marking assistance device includes a template member sized and shaped to positively engage a golf ball to be marked. The template member includes a main body that forms a resiliently-deformable retention cavity that frictionally secures a golf ball inserted therein. Articulation handles extending from opposite ends of the main body allow the template to be moved between a securing orientation and a release orientation. A marking slot extending through the main body allows use of a marking device to place diagnostic indicia, such as a stripe or stripes, onto the exterior of a golf ball secured within the retention cavity. The device may include indicia-protecting recesses that prevent unwanted contact between newly-marked indicia and the interior of the retention cavity. An attachment aperture allows connection of the device to a golf bag via a tethering member, and the device may include a marking device holder to removably secure a marking device when not in use.
