Title: Methods and apparatus for reducing inlet sleeve vibration
Inventor: HUANG KUO P
IPC: F01D25/28
Filed: 1991-12-23
Abstract: 56,204 ABSTRACT         The present invention substantially reduces the likelihood of cracking failure occurring in the inlet sleeves which connect a steam source to the outer cylinder of a steam turbine.  The present invention eliminates the excessive vibration which is the fundamental cause of cyclic stresses which cause fatigue cracking.  The present invention minimizes vibration by limiting the amplitude of the sleeve's oscillations of the inlet sleeve by preferably restraining the sleeve within a structure such as a disc having grooves cut therein which engage splines formed on the inlet sleeve.  The present invention provides sufficient clearance for installation but reduces the amplitude of radial oscillations.  The prevnt invention thus allows free vertical and radial sleeve movement of the inlet sleeve, but limit  random vibration that caused high-cycle  vibrations.  The present invention limits sleeve vibration in all directions, but does not introduce undesirable thermal stresses, while providing adequate cold clearance for installation ease.  Methods of assembling steam turbines are also disclosed.

Title: Roll-o-puck or ball bearing puck
Inventor: HINEY RONALD J
IPC: A63B67/14
Filed: 1992-12-09
Abstract: ABSTRACT The sport of Ice Hockey, usually played during the cold winter with skates or boots, has grown in popularity and is now being played year round. Enthusiasts have created in-line roller skates and play a dry land version of the game during thewarm seasons. Plastic discs and tennis balls replace the conventional hard rubber puck. Difficulty occurs when attempting to slide these puck-like discs or tennisballs on dry land surfaces. In this invention, the puck is designed with a roller ball, centrally contained therein, that allows the surrounding disc to float freely while the ball rolls over dry land surfaces. The disc is comprised of two parts, each identical; the two halves are fastened together to contain the ball in the roller socket and allow the ball to roll freely. The action reduces friction and more closely resembles a conventional puck sliding on an ice surface.

Title: Thyristor controlled series capacitor vernier control system
Inventor: LARSEN EINAR V
IPC: H02H9/04
Filed: 1992-11-06
Abstract: A firing control scheme for secure vernier operation of a thyristor controlled series capacitor (TCSC) (30) in series with a transmission line (24) uses phase controlled firing based on monitored capacitor voltage and line current. Vernier operation of the TCSC system (20) is provided by predicting an upcoming firing angle for switching the commutating circuit (32) to conduct a thyristor bypass current pulse therethrough. The current pulse causes an alternating offset component of voltage to appear across the series capacitor (30), in addition to the normal voltage component. Each current pulse changes the capacitor voltage proportionally to the integrated value of the current pulse. The TCSC system (20) promptly responds to an offset command from a higher-level controller (86), precisely controls the duty on the bypass thyristors (36a, 36b) to minimize thyristor damage, and prevents drift of the capacitor voltage away from a desired setting during line current disturbances.
