20090018592 | BONE SCREW FOR ORTHOPEDIC APPARATUS - A bone screw deforms on the same order as the bone, thus providing substantially uniform loading along an entire length of the thread of the bone screw. The bone screw of the present invention evenly distributes stress by matching the effective cross-sectional area of the bone screw times its modulus of elasticity with the effective cross-sectional area of the parent material (i.e. bone) times its modulus of elasticity so that they are preferably substantially equal to each other. | 01-15-2009 |
20090038342 | MOLTEN GLASS DELIVERY APPARATUS FOR OPTICAL QUALITY GLASS - A molten glass delivery system is modified to match it with the overflow downdraw process. A substantial number of defects not removed by the finer are diverted to the unusable inlet and distal edges of the sheet. In one embodiment, the stirring device is relocated from the outlet to the inlet of the finer. In another embodiment, the basic shape of the finer is preferably changed from a cylindrical shape to a Double Apex (or Gull Wing) shaped cross-section, whereby the apexes of the finer contain the glass that will form the unusable inlet end of the glass sheet. The finer vent or vents are preferably located at these apexes such that any homogeneity defects caused by the vents are diverted to the unusable inlet end of the glass sheet. The finer cross-section has a high aspect ratio for increased fining efficiency as compared to a cylindrical finer. | 02-12-2009 |
20100139321 | SHEET WIDTH CONTROL FOR OVERFLOW DOWNDRAW SHEET GLASS FORMING APPARATUS - A method keeps the width of the manufactured sheet substantially the same by attaching edge directors for the formed sheet to the manufacturing apparatus structure instead of to the forming block. Thus, sheet glass may be manufactured to specification for a longer time with the same forming block. An additional method adjusts the width of the manufactured sheet by changing the distance between the edge directors. Thus sheet glass may be manufactured to different width specifications with the same forming block. | 06-10-2010 |
20100162763 | OVERFLOW DOWNDRAW GLASS FORMING METHOD AND APPARATUS - The present invention discloses improved methods and apparatus for forming sheet glass. In one embodiment, the invention introduces a counteracting force to the stresses on the forming structure in a manner such that the thermal creep which inevitably occurs has a minimum impact on the glass flow characteristics of the forming structure. | 07-01-2010 |
20100229603 | OVERFLOW DOWNDRAW GLASS FORMING METHOD AND APPARATUS - The present invention discloses improved apparatuses for forming sheet glass. In one embodiment, the invention introduces a structural web that supports the forming structure in a manner such that the thermal creep which inevitably occurs has a minimum impact on the glass flow characteristics of the forming structure. | 09-16-2010 |
20110277504 | OVERFLOW DOWNDRAW GLASS FORMING METHOD AND APPARATUS - The present invention discloses improved methods and apparatus for forming sheet glass. In one embodiment, the invention introduces a counteracting force to the stresses on the forming structure in a manner such that the thermal creep which inevitably occurs has a minimum impact on the glass flow characteristics of the forming structure. | 11-17-2011 |
20120006057 | OVERFLOW DOWNDRAW GLASS FORMING METHOD AND APPARATUS - The present invention significantly modifies “The Overflow Process”. It includes a method and apparatus for measuring glass flow rate and maintaining a constant glass flow rate. It also embodies design features and methods that support and stress the forming apparatus in a manner such that the deformation that results from thermal creep is corrected, thus minimizing the effect of the thermal creep on the thickness variation of the glass sheet. The present invention also embodies design features that change the process from a single step (combined flow distribution and cooling) to a two step process; step one being flow distribution and step two being cooling. | 01-12-2012 |
20120101534 | Bone Screw For Orthopedic Apparatus - A bone screw deforms on the same order as the bone, thus providing substantially uniform loading along an entire length of the thread of the bone screw. The bone screw evenly distributes stress by matching the effective cross-sectional area of the bone screw times its modulus of elasticity with the effective cross-sectional area of the parent material (i.e. bone) times its modulus of elasticity so that so that the linear deformation of each is preferably substantially equal to the other. | 04-26-2012 |

20140148267 | MASS BALANCED GOLF CLUB - A modification to a golf club including a shaft extension and a balance weight provides a significant modification of the golf club mass distribution to affect the combination of forces and torques that the body, via the arms and hands, must exert on the golf club grip in order to impart motion to the golf ball towards the cup. A preferred design reduces the torque that the hands impart on the golf club grip to move the golf club through its controlled arc motion to strike the golf ball. The distributed weight of the golf club shaft contributes to a smoother motion of the golf club. | 05-29-2014 |
