Title: Incineration apparatus with improved wall configuration
Inventor: MUELLER JAMES H
IPC: F23G5/46
Filed: 1988-07-21
Granted: 1992-09-15
Abstract: ABSTRACT OF THE DISCLOSURE    An incineration apparatus is provided, preferably of the thermal heat regeneration type, in which noxious or other gases are passed to an incineration chamber, to be burnt at a suf-ficiently high temperature that they are disposed of, and in doing so, pass through heat-exchange beds of elements such as stones or the like, whereby the direction of gas flow may op-tionally be reversed.  The stoneware beds reside in recovery chambers adjacent but contiguous with the combustion chamber, separated therefrom by built-up refractory blockwalls.  The walls are of arcuate configuration and support the heat-retention elements in the recovery chambers.  The walls are generally the thickness of a single refractory block, and are of a radius that is less than any radius of the combustion chamber and are of a sufficient radius such that the forces of the stone or other heat-retention elements outside the walls may be resisted to prevent wall collapse.  With this wall configuration, the com-bustion chamber may be of any size, however massive, and yet the walls between the combustion chamber and recovery chambers are of a sufficient arcuate configuration to provide support for the stoneware.  In accordance with this invention, the walls of the combustion chamber may even be generally linear, if desired.

Title: Cutter for atherectomy device
Inventor: FARR ANDREW F
IPC: A61B17/32
Filed: 1988-10-13
Granted: 1993-07-13
Abstract: Abstract of the Disclosure A cutter penetrates at its forward end into, and excises, obstructive tissue in a lumen in a living being by providing two spaced external segments of a conical generally hollow portion with cutting surfaces at their edges.  The cutter may have a forward portion of restricted dimensions to facilitate the penetration of the cutter into the obstructive tissue.  A progressively expanding portion such as a truncated cone extends rearwardly from the portion of restricted dimensions. In this way, the cutter expands the area of excision of the obstructive tissue from the lumen wall at progressive positions rearwardly from the forward end.  The obstructive tissue in the lumen at the progressively expanding positions may be excised at the positions of penetration of the obstructive tissue by rotating the cutter manually or by a motor.  The cutter may then be moved forwardly to penetrate the obstructive tissue through an additional distance in the lumen.  The cutter may also have a hollow portion of substantially constant dimensions, such as a hollow cylinder, at the laterally expanded end.  This hollow cylinder is coupled to a torque tube which has strong and resilient properties to follow the contour of the lumen and to communicate a penetrating force to the forward end of the cutter and a torque to the cutter to rotate the cutter.  A vacuum may be applied to the cutter through the torque tube to remove fragments of obstructive tissue excised from the lumen.

Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE     A dispensing  package which automatically  relieves  residual pressure on a cream product and dispenses this product in incre-mental doses is disclosed.  The package uses a feed screw to drive an elevator which impels the cream product in a unidirectional manner.   The  drive  of  the  feed  screw  is  superimposed  with reciprocatory motion caused by internal  cams which retract the elevator.   By intermittently retracting the elevator a suitable distance, discrete amounts of the product are dispensed for each cycle  and  the  residual  pressure  on  the  product  is  relieved, preventing it from weeping onto the applicating surface of the dispenser.  The dispensing package is well suited to contain and dispense cream deodorants and antiperspirants.

Granted: 1993-06-29
Abstract: Abstract of the Disclosure A real-time database provides the predictable, high speed data access required  for on-line applications, while providing flexible searching capabilities.   The data retrieval routines include the option to "read-through-lock" to access data in locked data tables, the capability  to  directly  access  to  data  using  tuple identifiers,  and  the  capability  to  directly  access unformatted data from input areas which contain blocks of unformatted data.  The data updating routines include an option to omit index updating when updating data and an  option  to  update  data  in  a  locked  data  table. Multiple indexes can be defined for a data table.  Thus, high speed searches can be performed based on a variety of  data  fields.    The  data  storage  and  retrieval mechanisms  are  independent  and there are hash  index tables that connect the multiple index keys to the data tables.   The data table structure includes a column defined for storing tuple identifier strings.   These tuple identifiers can be used as pointers for chaining to  related  data  stored  in  other data  tables.    The database  has  relatively  small  programmatic  memory. There is a common structure for user data tables, index tables  and  system tables.    The  database  includes  a minimum  number  of  routines  with  certain  routines providing multiple functionality.
