Abstract: ABSTRACT OF THE INVENTION         Apparatus  and  method  for  securing  end  turn portion of coils  25  of  an  electric  generator  10.   A wedge-shaped strain block 49 is inserted between a pair of top 28 and bottom 31 stator  end turn  windings.  Compres-sible  fillers  58,  impregnated  with an insulating epoxy resin, are  located  between  the  top  52  and  bottom 55 surfaces of  the strain  block 49 and each of the windings 28,31.  The strain block 49 is driven inward to secure the windings, such that the fillers 58 are compressed to about 50% of their  original  thickness.    A  pair  of  top and bottom channels  61  help  guide  the  block  49 as it is inserted.  Glass fiber  bands 46  are then looped through openings 64  in the side of the wedge and around either of the windings 28,31.  If desired, the end turn windings can be  re-tightened  at  a  later  time by removing the glass bands 46, driving in the strain block 49  further, and re-securing the wedge in place.

Patent CA-2045263-A1 (CA)
Inventor: HARING JOHN MCMASTER
IPC: F02B75/02
Filed: 1991-06-21
Abstract: Disclosed are methods of and means  for an improved internal combustion engine performance and of substantially reduced or eliminated pollutants.   A relatively slow and long burning combustion is provided which produces an exhaust of high pressure which can be utilized to drive a turbocharger or cylinder or subsequent cylinders.  Ideally, the compression ratio is reduced with respect to current  internal combustion engines,  and the maximum temperature in the power or combustion cylinder can be below the temperature at which NOx is formed.   Preferably the pressure during combustion remains substantially constant and the air or air/fuel mixture is externally compressed 40 to 100% of its compression pressure in the combustion cylinder.  This results in a controlled energy release tailored to a change in volume per unit of time which results in more torque and horsepower,  less fuel consumption and drastically decreases pollution, both chemical and heat to the atmosphere.   A number of preferred embodiments are disclosed.

Inventor: SOOFI MADJID
IPC: B22D41/02
Filed: 1992-08-21
Abstract: An improved impact pad includes a plurality of channels which direct the flow of molten iron or steel toward the tundish drains, and ramps which elevate the flow in the directions of the drains.  The ramps cause the molten iron or steel to follow a trajectory path after leaving the impact pad, first rising and then falling toward the drains.  The trajectory path increases the residence time of the molten iron or steel in the tundish, allowing more time for impurities to float to the top of the vessel.  The trajectory path also helps propel the impurities partially toward the top of the tundish vessel.
