Granted: 1997-04-29
Abstract: A size reduction machine  for use  in process industries to continuously and precisely reduce the size of particles, while controlling fines, comprises an impeller mounted on a rotatable shaft, a drive operably connected to the shaft for effecting rotation of the shaft.  The shaft and impeller are vertically mounted within a vertically extending channel having an input and an output.  A screen has a tapered apertured wall formed in a frusto-conical shape. The screen is rigidly mounted within the channel so that any particles passing from the input to the output pass through the screen.   The impeller is  shaped and mounted so that a gap between an edge of the impeller and an interior of the screen remains substantially constant as the  impeller  rotates  relative  to  the  screen.    The improvement comprises the drive being operably connected to the shaft at a point under where the impeller is mounted onto the shaft.

Title: Active magnetic regenerator method and apparatus
Inventor: DEGREGORIA ANTHONY J
IPC: F25B21/00
Filed: 1993-06-02
Granted: 1996-09-10
Abstract: In an active magnetic regenerator apparatus having a regenerator bed of material exhibiting the magnetocaloric effect, flow of heat transfer fluid through the bed is unbalanced, so that more fluid flows through the bed from the hot side of the bed to the cold side than from the cold side to the hot side.  The excess heat transfer fluid is diverted back to the hot side of the bed.  The diverted fluid may be passed through a heat exchanger to draw heat from a fluid to be cooled.  The apparatus may be operated at cryogenic temperatures, and the heat transfer fluid may be helium gas and the fluid to be cooled may be hydrogen gas, which is liquified by the device.  The apparatus can be formed in multiple stages to allow a greater span of cooling temperatures than a single stage, and each stage may be comprised of two bed parts.  Where two bed parts are employed in each stage, a portion of the fluid passing from the hot side to the cold side of a first bed part which does not have a magnetic field applied thereto is diverted back to the cold side of the other bed part in the stage, where it is passed through to the hot side.  The remainder of the fluid from the cold side of the bed part of the first stage is passed to the hot side of the bed part of the second stage.  The fluid flowing from the cold side of a bed part of the second stage is partly passed to the cold side of the second bed part of the second stage and partly diverted back to the hot side of the first stage through a heat exchanger which draws heat from a fluid to be cooled.

Title: Digital video recorder
Inventor: OGURO MASAKI
IPC: H04N5/92
Filed: 1995-12-21
Granted: 2005-03-01
Abstract: A digital video signal is recorded in a first number of tracks in a standard play (SP) mode and in a second number of tracks in a long play (LP) mode, wherein each frame of the digital video signal is recorded in first and second sets of tracks in the SP mode and in only a first set of tracks in the LP mode, each track having subcode data recorded therein for locating frames during a high speed search of the record medium.      The digital video signal is compressed prior to recording in both the SP and LP modes, with the compression ratio being greater in the LP mode. When the digital video signal is recorded in the SP mode, the subcode data is of a first type for recording in the first set of tracks and is of a second type for recording in the second set of tracks; whereas when the digital video signal is recorded in the LP mode, only one type of subcode data is recorded. Hence, in the SP mode, a frame of compressed digital video signals includes subcode data of both types; and in the LP mode, a frame of compressed digital video signals contains subcode data of only one type.

Abstract: A plasma arc torch comprises relatively displaceable electrode  and nozzle components  having  first  and  second positions relative to one another in which the electrode respectively contacts the nozzle and is spaced an operating distance therefrom.  Arrangements are disclosed for relatively displacing the electrode and nozzle between the first and second positions  thereof with a pre-determined  force  of engagement therebetween in the first position, and without having to interrupt the flow of arc gas and/or the flow of arc current during such relative displacement.  A torch start up safety test procedure is performed by sequentially displacing the electrode and nozzle between the two positions thereof, sensing for appropriate open and closed circuit conditions therebetween, and enabling the creation of a pilot arc only when a pre-determined  sequence of  circuit conditions  is sensed.  Sequential displacement of the electrode and nozzle together with the application of a pre-determined force of engagement therebetween promotes cleaning of oxides from the area of contact between the electrode and nozzle.
