Abstract: F. 6066 MEDICAL APPLIANCE                    ABSTRACT OF THE DISCLOSURE     The invention contemplates a non-invasive technique and apparatus for artificially stimulating the venous-return flow of blood from the foot by inducing fast-rising pulsed squeezing or necking-down of the vessels of the venous-pump mechanism within the foot.  The stimulation results from transient flattening of the plantar arch, in that an induced transient spread of the heel with respect to the ball of the foot stretches, and therefore necks-down involved blood vessels; stimulation also results from such a squeeze of the plantar-arch region as to concurrently squeeze the involved blood vessels.  Cyclically inflatable devices, local to the foot-pump region, are disclosed for inducing either or both of the indicated actions; and enhanced arterial throughput is achieved when the stimulating pulse is sustained for a brief period prior to a relaxation dwell between pulses.

Abstract: ABSTRACT      A pump apparatus for viscous material adapted to be portable and includes a pair of upright supports defining a rigid framework mounted on a pair of wheels for movement along a support surface, such as a building floor.  A platform extends perpendicularly outwardly from the frame-work and is adapted to support a container of material.  A carriage is slideably mounted on a pair of guide rails secured to the framework, and a winch and cable assembly allows an operator to raise and lower the carriage.  The carriage mounts a linearly arranged motor, drive shaft and pump, with the pump having a downwardly extending, disk-like follower plate oriented parallel to the platform.          When a container is placed on the platform, the carriage may be lowered to insert the follower plate so that it bears against the material.  The motor drives the pump, and, as the material is removed from the container and dispensed through a hose, the weight of the carriage, pump and motor drives the follower plate into the container.          The motor is reversible and includes a two level pressure control for automatic operation.

Title: Steel rolling using optimized rolling schedule

Granted: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE          This invention is the process of rolling microalloyed steel  in  accordance  with  a  rolling  schedule  determined  as follows:     A  series  of  termomechanical  workings  such  as temperature-controlled  torsional  strains  are  applied  to  a specimen of  the  steel  at  strain  and  temperature  levels  and interpass times selected to simulate rolling mill conditions. The measured stress values are compared with the temperatures of the steel during the working periods  during which the  respective values were obtained.  Changes in the character of the functional relationship between  stress  and termperature  values  enable  a determination of the upper limit Ar3 of the austenite-ferrite transformation  temperature  range.    Thermomechanical  working schedules  are  repeated  at  selected  varying  starting  and terminating temperatures thereby to obtain a series of possible rolling schedules.   These simulations are selected so that  a varying number of reduction passes in the sequence occur at steel temperatures below temperature Ar3.   The value  of  a  selected parameter of the worked steel, e.g. yield strength, is measured at  ambient  temperature.    From  the  rolling  mill  analogue  of possible   rolling   schedule   simulations,   and  using   linear regression analysis, an optimized rolling schedule is selected which will  predictably  impart  to  the  steel  a  value  of  the selected parameter falling within a predetermined range.

Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE        In the past,  it  has  proven difficult  to  separate dirt and water from petroleum emulsions of the type found, e.g.  in settling ponds.  A relatively simple apparatus for effecting  such  separation  includes  a  sifter  or  screening device for removing large solid impurities from the emulsion, a  preheater  for  reducing the viscosity of the emulsion,  a centrifuge  or  filter  for  separating  most  of  the  dirt particles from the emulsion,  a settling tank for receiving the emulsion from the dirt separator,  and an evaporator for separating most of the water from the petroleum.  The dirt removed  in the dirt  separator  with  residual  oil  attached thereto is mixed with a fuel oil and burned to create the heat  necessary  to  evaporate  the  water.   The  petroleum separated in the evaporator is cycled through the preheater for   heating   incoming   dirty   petroleum   emulsion.    The evaporator  contains  trays  carring  a  plurality of  rows  of tubes.   The  water-containing  emulsion  is  fed  into  the uppermost tray into heat exchange contact with the tubes.            The emulsion overflows through overflow pipes into subjacent trays, which also contain heating tubes.  Hot gas is produced by  burning  the  mixture  of  dirt  and  fuel  oil  are passed through the tubes in the trays to heat the emulsion and cause evaporation of the water.
