Patent CA-2180985-A1 (CA)
Title: Surface traveling wave vehicle
Inventor: REED NORMAN O
IPC: B62D57/02
Filed: 1996-08-22
Abstract: A Surface Traveling Wave Vehicle has propulsion and support provided by a flexible sinuous skin.  This invention is a new embodiment which does not relate to existing technologies.  In a propulsion and support unit for a vehicle, it is known that a means of movement over a non level terrain, and the capability to support the driving mechanism and a load must be provided. The 'per-cycle' surface length of the sinuous flexible skin, being longer than its projection onto the traveled surface, results in a net longitudinal motion as the flexing occurs. This global transporter, in lengths from meters to hundreds of meters, is made feasible by use of this principle and the application of modern day materials technology.

Title: Rf link control of satellite clocks
Inventor: CUMMISKEY PETER
IPC: G04R20/00
Filed: 1995-06-01
Abstract: A system and method for maintaining a precise time standard among a system of orbiting satellites is disclosed. In an illustrative embodiment (the figure), atomic clock data is circulated among the satellites (2, 4, 6) via RF crosslinks (10). Each satellite uses the received data as input to a Kalman process which acts to minimize the means squared error among the satellite clocks to form a set of "ensemble clocks". The resulting ensemble clock values are then transmitted (12) to an earth station (8) where an offset between the ensemble clocks and Universal Time is computed. The offset is transmitted (14) from the earth station to the satellites where it is used by the satellites to lock their on-board clocks to Universal Time, thereby creating a corrected system time. The corrected system time is transmitted. via RF crosslinks (10) to satellites not having operational on-board clocks. The satellites without atomic clocks employ phase locked loops to anchor their clocks to the corrected system time as it is received over the crosslinks.

Inventor: NOLIN BRIAN JAMES
IPC: A63B53/14

Abstract: November 15, 1996 Putter Grip This design of the grip is intended to help: 1. The path of the putter head to stay on the intended line of direction longer.2. Keep the angle of the face of the putter square to the intended line of direction longer. 3. Make it easier to do both of the above.            This will help to hit more accurate putts.   The grip has a counter balance weight. The grip design incorporates an angle from the axis of the grip to the axis of the putter shaft slot. This is evident when viewed facing the face of the putter head. Thus, the hands are not around the shaft while holding the grip, but more between the putter and the body of the player. The hands, wrists, arms and stoking movement are more natural when using the putter. The grip is adapted to the users/player. This causes more accurate performance. The composition and dimensions are within the rules of golf.

Title: Method and Apparatus for Thermal Process Control in the Electroforming of Stampers for Production of CD/LD Data Carriers
Inventor: GUBIG ANDREAS
IPC: C25D1/10
Filed: 1997-01-22
Abstract: A method and an  apparatus  for  thermal  process  control  in electroforming  stampers  for  the  production  of  CD/LD  data carriers or the  like.   The temperature of an electrolytic solution in an electroforming cell is maintained at a value nearest a specific maximum temperature by raising or lowering the temperature of the electrolytic solution in a storage tank provided outside of the electroforming cell as a function of the  temperature  measured in  a  cathode  space  of  the electroforming cell. A temperature sensor is disposed in or near  the  cathode  space  adjacent  an  electrolyte  injection nozzle in a space between the anode and cathode means for supplying signals to a control unit. The temperature sensor and  the  injection nozzle  are  preferably  assembled  into  a single mounting unit. The electroforming process can thus be run with an optimum effectivity in the vicinity of a maximum permissible temperature of the electrolytic solution.
