Patent CA-2115598-A1 (CA)
Title: Baseball pitching practice zone
Inventor: MACDONALD DOUGLAS O
IPC: A63B63/00
Filed: 1994-02-14
Abstract: It  is common and generally accepted that in order to develop  pitching skills a baseball pitcher practices within an environment  unlike  that  of  the real game of baseball.  This invention  provides  for  an  indoor  centre  infield  pitching practice  environment which emulates that of the actual game of baseball  and  also  is  electronically  equipped to assess and display  certain  conditions of pitched balls.  The combination of   the  apparatus  which  attempts  to  physically  create  a baseball   game   environment   comprises  a  pitcher's  mound, constructed  a  specified  distance  from  a  home plate target area,  batter, catcher and umpire human figures having baseball attire  and  equipment, all positioned in a ready for the pitch stance.    These movable figures are designedly placed near the home  plate area having a home plate, batter's boxes, catcher's box  and  partial  base  line  markings  emulating  those  of a baseball  infield.    After  receiving the practice ball at the mound,  tossed  by  a  user-actuated mechanical device near the home  plate  area,  the  user  can  now  prepare  to  deliver a practice  pitch to a simulated actual game target.  The pitched ball  may  then  be  electronically  assessed  for accuracy and speed,   and  electronically  registered  values  may  then  be displayed  for  the  user.    This  invention also provides for video  cameras,  strategically  mounted and optionally operated to record the mechanics of the user's delivery.            A  preferred  alternative  to  the use of the three dimensional resilient  human figures is the use of photographic projections onto  a  resilient  screen  which  will  absorb  and resist the frequent  impact  of  pitched  balls.    This alternative could create  a  combination  of  a  two and three dimensional target area   and   allow  for  an  effective  method  for  positional alterations of the human baseball figures.

Title: Flow-mobile
Inventor: ENIOJUKAN DAVID OLORUNFEMI
IPC: F03B17/00
Filed: 1994-08-04
Abstract: This invention relates to, and is an improvement in, thrust-producing mechanisms which utilize the principle of centrifugal force to generate resultant force in a given direction.  The FLOW-MOBILE invention is a new device which comprises means for causing a mass of fluid to circulate at high speed continuously round an endless flow tube that is securely wrapped several times around the inner and outer surfaces of a rigid semi-cylinderical or semi-toroidal shell or other rigid support of similar shape.   The mobile mass of fluid may consist of any liquid having suitable physical and chemical characteristics and may be kept in motion by suitable pump(s) driven by motor(s) or appropriate power source(s).  The resultant linear force which constitutes the thrust of the FLOW-MOBILE, is derived from the centrifugal pressure exerted on the flow tube walls by the fast moving mass of fluid.
