Patent CA-2116604-A1 (CA)
Inventor: MAYNARD ROBERT A
IPC: A01K97/05
Filed: 1994-02-28
Abstract: An improved minnow container that is adapted to carry water and oxygen therein when in an upright position is disclosed. The container comprises a water receiving and retaining chamber that is substantially open at its bottom end and has a first opening in the top thereof and an oxygen receiving and retaining chamber that is substantially open at its bottom end and is sealed above the open bottom end so as to preclude the escape of oxygen therefrom when the container is in its upright position. A barrier means physically separates the oxygen receiving and retaining chamber and the water receiving and retaining chamber so as to preclude the passage of fluid between the water receiving and retaining chamber and the oxygen receiving and retaining chamber. The barrier means terminates at a lower boundary in a passageway that is generally below the barrier means. The passageway connects the water receiving and retaining chamber in fluid communication with the oxygen receiving and retaining chamber. When the container is in use in its upright position, the oxygen receiving and retaining chamber contains oxygen, the passageway contains water, and the water receiving and retaining chamber contains water above the level of the passageway, and the oxygen is precluded from exiting the oxygen receiving and retaining chamber. The container is adapted to pass oxygen from the oxygen receiving and retaining chamber through the passageway and into the water receiving and retaining chamber, and concurrently to pass water from the water receiving and retaining chamber through the passageway and into the oxygen receiving and retaining chamber, when the container is rotated from its upright position to a fully rotated position, whereat the oxygen receiving and retaining chamber is substantially filled with water, which is held therein by ambient air pressure in the water receiving and retaining chamber. Oxygen is then added into the oxygen receiving and retaining chamber.

Abstract: MAGNETIC COMPACT DISK AUXILIARY MEMORY AND METHOD OF USING THE                           LATTER          ABSTRACT OF THE DISCLOSURE     A compact disk auxiliary memory for storing information on a conventional compact disk. The conventional compact disk has a primary memory region wherein information is stored In the form of optical data. The primary memory region is located on a first surface of the compact disk. The compact disk auxiliary memory of the present invention Is adapted to be positioned on an opposed compact disk surface. The auxiliary memory preferably takes the form of an annular-shaped substrate which is adapted to be either adhesively bounded or embedded on the compact disk. The information is thus adapted to be transferred to and from the compact disk auxiliary memory by a conventional magnetic read/write head. Since the memory substrate has a substantially annular configuration, the conventional disk driving mechanism of a conventional compact disk player can be used positioned the memory substrate in a proper relative relationship with a magnetic head for transferring data between the magnetic head and the compact disk auxiliary memory.

Title: Method and apparatus for determining parameters of the motion of an object
Inventor: THOME JAMES PATRICK
IPC: G01S17/58
Filed: 1993-01-22
Abstract: The present invention provides an apparatus (10) for determining a desired parameter of the motion of an object. The device (10) can be used to calculate the estimated carry distance of a golf shot. The golfer (16) uses a keypad (26) to enter the club (14) bating used and the units of measure desired for the output display (24). A Doppler radar system (34) is employed to illuminate the ball immediately after it has been hit. A reflected signal is detected and difference pulses are generated, having a frequency which is proportional to the velocity of the ball. The microprocessor is used to calculate the carry distance by relating the average period of the difference pulses to a projected carry Distance through empirically determined data. The carry distance can be displayed on the device (10) or on a remote display, and/or can be stored in memory for later recall or transmission to an external computer (118).

Title: Random orbit sander having air directing baffle
Inventor: HOWARD THOMAS J JR
IPC: B25F5/02
Filed: 1995-02-20
Abstract: ABSTRACT OF THE DISCLOSURE         An air directing baffle for a random orbit sander.   The baffle  includes  a main body portion forming an annular opening, a pair of neck portions extending approximately circumferentially opposite from one another, and a pair of recessed portions formed in each of the neck portions.  The neck portions extend into airflow registration with a plurality of exhaust slots formed in a shroud rotatably disposed at a lower portion of a housing of the sander.   The annular opening  is  adapted  to  fit  over  a  boss  portion protruding from a lower face surface of the housing of the sander to thus permit the baffle to be rotated freely relative to the housing.  The recessed portions in each of the neck portions of the baffle inwardly engage with a pair of inwardly protruding shoulder portions formed in an interior area of the shroud.  The interengagement of the baffle with the shroud permits the neck portions of the baffle to be maintained in alignment with the exhaust slots in the shroud as the shroud is rotated by a user during operation of the sander.  Thus, the baffle is free to rotate relative to the housing but not relative to the shroud itself.  The baffle serves to more effectively direct a cooling airflow drawn in by a fan through inlet slots in a top member  associated  with  the  housing  such  that  the airflow is more directly exhausted from the interior area of the shroud.  The design of the baffle further does not complicate the assembly of the sander 10 or otherwise add significantly to the overall cost of the sander.
