Title: Non-linear inductor with magnetic field reduction
Inventor: DYE MALCOM
IPC: H01F29/14
Filed: 1992-07-29
Abstract: ABSTRACT      A non-linear inductor for a CRT line timebase circuit comprises a bobbin 40 carrying an inductive coil 41 and a first permanent magnet 42 adjacent the coil 41.  A second permanent magnet 200 is positioned and oriented relative to the first magnet 42 in such a manner that the magnetic field generated  by  the  non-linear  inductor  is  substantially reduced. Because the second magnet 200 is integral, the non linear inductor occupies the same printed circuit board area as a conventional non linear inductor. Furthermore, because the second magnet 200 is oriented to substantially cancel the magnetic field, no additional magnets are required for deflecting the magnet field away from the CRT.

Abstract: ABSTRACT OF THE DISCLOSURE    An infant-restraining protective seat (1) includes a seat back (3) tiltably attached to the body (7) of a seat portion via a turning shaft (20), with the seat portion (2) and seat back (3) being foldable.  A torsion spring (54) is interposed between the body (7) of he seat portion and the seat back (3).  The torsion spring (54) is adapted to assume a free state when an upper hook pin (52) is at an .alpha. position.  Under these conditions, the seat back (3) is capable of tilting forward to .beta. under its own weight.  When the seat back 3 is tilted in the direction of .beta., shock is mitigated by the torsion spring (54).  When the seat back (3) is tilted toward .gamma. and .delta., half-latching and play in the back-and-forth direction are prevented.  When the infant-restraining protective seat (1) is not in use, the protective seat is folded up to reduce its size and can then be stored.  The seat (1) can be carried about and set up on a vehicle seat much more easily.  In addition, only a small amount of space is necessary for storage.

Abstract: A vacuum powered automatic swimming pool cleaning device having a hollow housing supported on two pairs of device mover wheels.    The housing includes a central water suction chamber in water flow communication with a water suction trough at the bottom of the housing and in water outlet communication with an external vacuum line, a gear train for driving one of the pairs of mover wheels, and pivoted directional control floats.    The water suction  chamber houses an axle mounted turbine wheel bearing water driven vanes with the turbine being rotated in one direction only by water flow through the chamber.    The turbine axle bears a turbine power output drive gear which intermeshes with  one  or  the  other  of  two shift  gears  which  in  turn reversibly drive the gear train as dictated by the position of the directional control floats within the housing.   The floats swing shift within the housing to shift the shift gears in response to the impact of the cleaning device on an obstruction on the pool floor or by the device impacting a vertical pool wall.      The swing shift of the control floats reverses the rotation of the mover wheels and thus the direction of movement of the cleaning device on the pool floor.

IPC: G01R31/36
Filed: 1993-02-23
Abstract: A digitizer tablet computer has a host processor connected to a service processor which,  in turn,  is connected to a digitizer   controller  and   to   a   power   subsystem microcontroller.  A battery supplies the primary power for operating the computer but the computer is also connectable to an external source of DC power to charge the battery and to operate the computer when it is not running on battery power. The service processor includes a battery gauge the contents of which indicate how much power is left in the battery and how much time remains at the current rate of power consumption before the power runs out. The amount of remaining power in the gauge is determined by keeping track of power consumed, power added,  and power lost during off periods.  The use of the  second derivative  of a voltage versus  time  discharge  curve  creates  a point  from which relative accurate estimates can be made of how much longer the computer can be operated.

Abstract: An intermediate weight member (10) having a variable cross-section or bending moment of inertia as a function of member length is disclosed.  At one end of the member (10) a slip and elevator section (14) is provided.  A partially grooved section (16) of a diameter greater than that of the slip and elevator section extends between the slip and elevator section (24) and the other end of the member (10).  The partially grooved section (16)  includes two variable depth grooved sections  (18,  20) separated by an ungrooved section (22).  The ungrooved section (22) includes hardbanding rings (26, 28).  The spiral grooves (30A, 30B, 30C) of variable depth grooved section (18, 20) vary in depth as a function of member length such that the bending moment of inertia varies as a function of length from the slip and elevator section (14) to the lower end of the member (10). Such variation changes from a constant bending moment of inertia at the slip and elevator section (14) to a substantially greater bending moment of inertia at the ungrooved section  (22)  and thence to a lower bending moment of inertia of a reduced diameter section (24) at its other end.
