Title: Liquid proportioning system
Inventor: KOSUP GILBERT G
IPC: G05D11/13
Filed: 1990-10-24
Granted: 1996-10-22
Abstract: A  liquid  proportioning  system  constructed according to the principles of the present invention mixes a primary liquid with liquid additive from at least one liquid additive reservoir.  The system includes a manifold in which the primary liquid and the liquid additive are mixed.  The manifold has an outlet for discharging the mixture, a first inlet for receiving the primary liquid and a second inlet for receiving liquid additive.  A plurality of conduits each carry the liquid additive to the manifold from the liquid additive reservoir.  Each conduit delivers the liquid additive to the manifold at  a   different rate under substantially the same operating conditions so that the connection of each conduit to the second inlet results in a different predetermined mixing proportion.   Quick connect couplings connect each conduit to the second inlet of the manifold so that the   conduits   may  be  quickly connected to and disconnected from the second inlet to change the mixing proportion.

Title: Magneto-optical memory device whereon overwriting operation can be carried out through light intensity modulation and method for recording and erasing using it
Inventor: OHTA KENJI
IPC: G11B11/10
Filed: 1992-10-22
Granted: 1996-05-28
Abstract: A magneto-optical memory device is provided with a recording track having a recording film and a guide track.  In the guide track is formed a perpendicular magnetic film, whose magnetization direction is arranged in one direction.   The recording track and the guide track are alternately disposed. A recording operation is carried out, using a circular magnetic field  generated  by  the  perpendicular  magnetic  film,  by projecting a light beam only on the recording track so as to raise the temperature of the recording film.  When erasing, the light beam is projected on the recording track and respective portions of the guide tracks located on both sides of the recording track so as raise the temperature thereof.  As the temperature  rises,  the magnetization  of  the  perpendicular magnetic film is reduced, and an erasing operation is then performed using an external magnetic field.

Title: Selectively actuatable lighter
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/16
Filed: 1992-06-30
Granted: 2000-04-11
Abstract: A selectively actuatable lighter device is disclosed which includes a body (12) defining reservoir (15) for containing a combustible gaseous medium such as butane (9), and having a valve (28) arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. Such lighter can selectively produce sparks at a location proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device embodies a resiliently releasable latch (16) which normally prevents actuation of a valve actuator (14) to the open position thereby preventing actuation of the valve. The latch (16) is selectively movable to a position out of interference with the valve actuator, so that the gaseous medium may be released and ignited by the sparks. The latch is resiliently structured and mounted such that once a flame is produced and the valve actuator (14) is released, the latch (16) returns to its closed or latched position to prevent actuation of the valve (28) to the open position by prevention of the pivotal motion of the valve actuator (14). To "re-use" the lighter, the latch must again be moved to an unlatched position so that the valve actuator (14) can be opened for subsequent ignition of the gaseous medium.
