Title: Computer with provision for continued operation during battery change
Inventor: DULANEY KENNETH L
IPC: G06F1/26
Filed: 1990-06-11
Abstract: COMPUTER WITH PROVISION FOR CONTINUED     OPERATION DURING BATTERY CHANGE                 ABSTRACT OF THE DISCLOSURE    In a battery powered computer, a bridge battery circuit provides power to the computer for a short period of time while the main battery is removed and changed.          This enables the computer to be left partially on, but in a quiescent state, without committing the active program and data to disk or card memory while the battery is being changed.  A very small embedded battery or bridge battery automatically powers the RAM of the computer upon removal of the main battery, following transfer of the computer to a standby mode wherein all active programs are temporarily stored in RAM.  A quick charge circuit in the computer provides several minutes of fast charging of the bridge battery whenever a new battery is inserted.  A very low trickle charge may be applied continuously after fast charging.

Abstract: A spray nozzle comprises a hollow body having an inlet, an outlet and a fluid flow passage therebetween.  The body contains a pressure-responsive or a pressure responsive and temperature responsive valving element that increases the effective area of the outlet in response to an increase in pressure or an increase in pressure and/or temperature.  In a preferred embodiment, the outlet includes a restricted orifice and an unrestricted orifice, and the valving element is movable within the body between a first position in which the restricted orifice is open and the unrestricted orifice is closed, and a second position in which the unrestricted orifice is open.  The valving element is biased in the first position by a spring which applies a selectable biasing force that defines a threshold pressure, so that the valving element is moved to the second position by a dynamic pressure of the fluid flowing through the flow passage that is greater than the threshold pressure.  In an alternative embodiment, the outlet is provided with a resilient occluder having an orifice that increases in area as the occluder is flexed axially in the downstream direction in response to an increase in the dynamic pressure of the fluid flow.
