Abstract: A quick disconnect fluid coupling for a liquid-cooled, preprogrammed card for an aircraft communication or navigation system, the coupling being made up of male and female coupling elements which are closed to flow in the free or uncoupled state and which are open to flow when coupled.    The male  coupling element  has  an  integral pressure relief feature which operates in two phases.  In a first phase the male coupling element remains closed to fluid flow, but accommodates an increase in fluid pressure by movement of an annular valve sleeve within in outer annular member to increase the fluid volume within the annular member.  In a second phase an end of a valve member of the male coupling element is biased away from sealing engagement with an end of the annular valve sleeve by fluid pressure, against the biasing effect of a return spring which is trapped between the annular valve sleeve and a perforate annular retainer that is affixed to an opposed end of the valve member, to permit fluid to be dumped from the coupling element.

Title: Wiper System
Inventor: SATO KATSUTOSHI
IPC: B60S1/08
Filed: 1993-08-19
Abstract: To allow compact design of a wiper system equipped with a wiping angle varying assembly which comprises an actuating motor, an eccentric cam member provided in a path of transmitting the movement of the output end of a wiper motor to a wiper arm, and a control unit for activating the actuating motor so as to move the eccentric cam member and thereby change the range of angle of the wiping movement by altering a configuration of a linkage structure provided between the wiper motor and the wiper arm, the control unit is adapted to activate the eccentric cam member with such a timing that the force transmitted through the linkage structure from the wiper motor to the wiper arm tends to assist the force produced by the actuating motor to move the eccentric cam member in the required direction.  Thus, the requirement of the power output of the actuating motor can be reduced, and the actuating motor can be substantially reduced in size. As a result, the design of the wiping angle varying assembly is simplified, and the assembly may be conveniently incorporated in a linkage structure similar in structure to the conventional linkage structure for wiper systems not equipped with any wiping angle varying assembly.
