Abstract: VARIABLE-RATIO TRANSMISSIONS, SEPARATELY AND IN BICYCLES                 ABSTRACT      Drive  mechanism,  particularly  for  use  with  a bicycle, of the type having variable diameter drive and driven  members  connected  by  an  endless  belt  which engages adjustable segments on the members.  Through a control  means  the  drive  ratio  can  be  adjusted  to multiple, discrete settings.  Belt wrap is maintained between the belt and the drive and driven members at all  settings by two  idlers which  are  independently supported for movement.   A locking rail  is used to release and secure the segments on the members and a split clutch is used with the driven member for easy rear wheel removal.  The mechanism has a lost motion device to accommodate  forward  and rearward pedaling without  harming  the  drive  mechanism.   The  drive mechanism is modular in construction so it can be used with frames of varying sizes and the drive mechanism can be quickly removed from or assembled to the bicycle frame when replacement is desired.

Abstract: The   present  invention  provides  a  method  for selecting magnetite to form a dense media  for  benefi-ciation  of  fine particulate solids such that the par-ticulate solids are as  buoyant  with  respect  to  the dense  media  as  if  the  solids were in a true liquid having a specific gravity equal to that  of  the  dense media.    The  method  involves determining a magnetite particle diameter such that the diameter ratio of  par-ticulate solid to magnetite lies above a diameter ratio partition curve.  The invention is also directed toward using  magnetite  having  a particle diameter less than about 0.005 mm and a mean particle  diameter  of  about 0.0025  mm.   Such magnetite is formed from a gas phase pyrohydrolysis reaction on an  aqueous  iron  (ferrous) chloride solution.    The present invention is further directed towards  a  method  for determining  the  ef-ficiency of separation of a dense media separation pro-cess.    This  method  includes determining an apparent distance a  particle  must  travel  in  a  dense  media cyclone  to  be correctly beneficiated.   From this ap-parent distance,  an apparent velocity a particle  must achieve  to  be  correctly  beneficiated is calculated. This apparent velocity is used, along with cyclone geo-metry and operational parameters to calculate a  diver-gence  value  which indicates the efficiency of separa-tion.  The present invention also includes a method for selecting cyclone  geometry  and  operating  parameters which  includes  determining  separation efficiency and adjusting geometry and parameters in a manner to obtain improved efficiency.

Abstract: Process and device for cooling a tubular sleeve produced by hot extrusion-blowing of a thermoplastic material through an annular die. In the process, a stream of primary air is flowed under pressure substantially parallel to and spaced from the tubular sleeve and reaches the tubular sleeve at a second stage. The stream of primary air induces a stream of secondary air which flows substantially parallel and proximate to the tubular sleeve at a first stage and whose flow is substantially laminar over most of its path. The device includes a first cylindrical sleeve member that, in combination with the tubular sleeve, defines a secondary air flow space. A second cyclindrical sleeve member and the first sleeve member define a primary air flow space therebetween. A cylindrical ring disposed proximate to the annular die directs air into the secondary air flow space. A source of pressurized air is in flow communication with the primary air flow space.

Abstract: An intravascular catheter designed to apply a liquid medicament or other substance to a stenotic lesion as the blood vessel is undergoing dilatation to facilitate the restoration and long-term maintenance of patency to the blood vessel.   It comprises three concentrically arranged  flexible  plastic  tubes  and  a  pair  of concentrically arranged expander members located at the distal end of the tubes.  The space between the outer wall of the inner tube and the inner wall of the intermediate tube is in fluid communication with the interior of the first expander member while the space between the outer wall of the intermediate tube and the inner wall of the outer tube is in fluid communication with the interior of the second expander member.   A plurality of minute holes are formed through the second expander member such that when the liquid medicament is introduced into the lumen of the outer tube while an inflation fluid is introduced into the lumen of the intermediate tube, both expander members inflate with the drug or other substance being ejected out through the tiny pores of the outermost expander member while continued  inflation  of  the  inner  expander  member provides the necessary pressure for dilatation of the lesion.

Abstract: RETRACTABLE CONTROL UNIT FOR REFRIGERATORS     ABSTRACT OF THE DISCLOSURE         A retractable temperature control for refrigeration units includes a control panel pivoted for movement between an extended, accessible position and a retracted position in which it is enclosed within one of the insulated walls of the unit.  Mounted on the panel are two operators, one of which controls the temperature of a thermostat and the other of which controls the position of a damper.  Adjustment of the operator associated with the thermostat controls the tempera-ture of one compartment in the refrigeration unit and adjust-ment of the other operator controls the position of a damper, and in turn controls the differential temperature between the two compartments provided by the refrigeration unit.  The thermostat and the damper control are structured so that movement of the control panel between the retracted and extended positions does not affect the adjustment thereof. When the controls are in the retracted position, they do not interfere with the placement of articles stored within the refrigeration  compartments.   Further,  retraction of  the controls prevents accidental damage of the controls and/or accidental change in the adjusted positions thereof.

Abstract: The invention is both a system and method for continuously separating heavier from lighter isotopes of a particular element, such as zirconium. The system comprises a housing, a column assembly rotatably mounted with respect to the housing which includes a plurality of vertically oriented separation cells arranged in a circle, each of which contains a packing material, both a feed electrolyte source and a barren electrolyte source, each of which has an outlet mounted in the housing for continuously introducing either a feed electrolyte or a barren electrolyte into each of the cells as they rotate past the outlets, and upper and lower electrodes disposed over the upper and lower ends of the separation cells for, inducing the electro-migration of the lighter zirconium ions toward the lower ends of each of the separation cells. A drain assembly disposed beneath the column assembly continuously collects isotopic enriched electrolyte from the bottom ends of the separation cells. The speed of rotation of the column assembly is coordinated with the rate of eluent flow through the cells so that the same segments of the annular tray of the drain assembly continuously collect eluent enriched in a particular type of zirconium isotope.
