Inventor: ALBERT GREGORY P
IPC: B25F5/02
Filed: 1990-03-23
Granted: 1995-02-28
Abstract: The tool has a circular body, and an actuating lever pivotably coupled thereto.  The lever, however, has two limbs, joined through a bight, and one of the limbs is fully nested in a recess formed therefor in the body.      Consequently, one may grasp the tool about the body, whereat the one limb is nested, without turning the tool on, inadvertently.  The other limb extends outwardly from the body, however, and by grasping the tool thereat, and depressing this other limb, the tool is turned on.

Title: Moving image signal encoding apparatus and decoding apparatus
Inventor: NAGATA ATSUSHI
IPC: H04N7/46
Filed: 1990-05-10
Granted: 1994-02-15
Abstract: ABSTRACT OF THE DISCLOSURE        A  moving   image   signal  encoding   apparatus comprises  a  frame  decimating  circuit  for  extracting encoded  frames  from  an  input  moving  image  signal  at specified  intervals,  a  frame  interpolating  circuit  for obtaining  an  interpolated  frame  between  the  encoded frames,  and a circuit for obtaining an error formed by frame  interpolation.    A  moving  image  signal  decoding apparatus comprises a receiving circuit for extracting a frame  code  from  an  inputted  signal,  a  frame  decoding circuit for decoding the frame code to obtain a reproduced frame, and a frame interpolating circuit for obtaining an interpolated  frame  between the  reproduced  frames.  By transmitting an error of the interpolated frame from the encoding   apparatus   to   the   decoding   apparatus   and correcting the error of the interpolated frame with the decoding apparatus, the error of the interpolated frame is eliminated. Alternatively,  depending on the value of the error of the interpolated frame obtained with the encoding apparatus,  circuit determines  the  operation mode as  to whether  the  frame  interpolating  circuit  of the decoder carries out frame interpolation or preceding value holding and  sends  a  flag  to  show  the  operation  mode  to  the decoder,  so that improvement is given when the error of the interpolated frame is large.

Title: Stove for wok cooking
Inventor: LOK YUK LEUNG
IPC: F24C3/08
Filed: 1991-01-22
Granted: 1997-09-16
Abstract: A stove suitable for large-burner cooking generating a high heat exhaust has an enclosed stove casing with an upper cooking surface, a hollow interior, and a burner well recessed into the interior of the casing.  A large burner is positioned in the burner well, and a cooking vessel can be placed over the well so as to close the burner flame off from the outside.  The burner well preferably supports a wok or other rounded-bottom cooking vessel.  The high heat exhaust from the burner is trapped in the well and entrained by natural convection into a duct member to a duct casing at a rear side of the stove.  The duct casing has a double wall construction and baffles in its interior forming a labyrinthine  channel  for  mixing  cold  air  supplied  through openings in the stove casing and the hot exhaust air from the large  burner.    The  stove  includes  a  catch  basin  member positionable in the interior of the burner well for catching any spillage or debris.  The stove casing has a window formed in its front panel for allowing the stove user to visually check the burner flame.  Further features include a recessed burner plate positionable in the well over the burner for allowing cooking with other types of cooking vessels, and a grill positionable over the annular rim of the stove and a deflector unit below for open-flame cooking when the wok is not used.

Patent CA-2060292-C (CA)
Inventor: STEPHENSON EVERETT HAROLD JR
IPC: B60P7/08
Filed: 1992-01-29
Granted: 2001-11-20
Abstract: A remote release mechanism is disclosed which permits restraints such as flat straps placed around a load and placed in tension by a winch to be released by an operator positioned on the same side of the transportation structure as the winch. Thus, the present invention permits the hook end of a load restraint to be released from the winch side of the transportation structure, thereby eliminating the need to perform separate operations on either side of the restraint mechanism. In a preferred embodiment, the present invention provides apparatus comprising a hook bar connected to a rotatable drum which is held from rogation in one direction by a ratchet and pawl. Upon release by the application of force to a remote release rod, the hook bar is released and permitted to rotate, thereby causing the hook which connects the restraint to the hook bar to fall away, releasing the restraint. Methods of remotely releasing a load restraint are also disclosed.
