摘要： A regulator adapted to regulate the throughput of an ink between an ink source and a print head includes: (a) a pressurized chamber including an ink inlet in fluid communication with the ink source, an ink outlet in fluid communication with the print head, and at least one flexible wall; and (b) a lever including a flexible arm extending along a portion of the flexible wall and an opposing arm operatively coupled to a seal biased to close the ink inlet when the lever is in a first position and to open the ink inlet to allow fluid communication between the ink inlet and the pressurized chamber when the lever is pivoted to a second position; where a lower pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm, pivoting the lever to the first position (inlet closed), where a higher pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm to pivot the lever to the second position (inlet open), and where a pressure change from the lower pressure differential to the higher pressure differential across the flexible wall causes the flexible wall to actuate and flex the flexible arm without causing the lever to pivot.

摘要： A fluid pressure transducer assembly (10) includes an exemplary silicon or ceramic capacitive transducer (22) having a relatively flexible diaphragm portion (22e) mounted on a ceramic substrate or circuit board (18) over a bore (18a) so that the diaphragm is exposed to fluid pressure from a port (12m) received through the bore. The circuit board is received in a plastic housing (12) laterally positioned by guides (12e, 12f) on three height control pins (12d) to vertically position the circuit board a defined, precise distance above a platform (12b) on which a bead of adhesive sealing material has previously been placed, the sealing material having a height greater than the distance between a plane in which the free end of the height control pins lie and a plane in which the top surface of the platform lies. As a result, the circuit board is sealed to the plastic housing through a bead having a uniform, precise height all around its circumference to isolate temperature expansion stresses. According to another feature of the invention an electrically conductive layer (30a) is formed on the top surface of the circuit board beneath the transducer (22) and another electrically conductive layer (30b) is formed on the top surface of the transducer (22) electrically joined together to form an EMI shield.

摘要： A rigid, non-metallic laminate suitable as a fire barrier, made by impregnating a layer of non-metallic fibers other than glass fibers with a resin, coating glass fibers with a refractory aluminum silicate to form a sheath, superimposing a layer of the thus alumina silicate coated glass fibers on the resin impregnated layer of non-metallic fibers and then subjecting the resulting laminate simultaneously to heat and pressure to squeeze resin from the non-metallic fibers into the interstices of the alumina silicate coated glass fibers and to cure the resin binder. A rigid multi-layer laminate in a common resin binder useful as a fire resistant panel or duct for a gas turbine engine results.

摘要： An ink jet printhead assembly for a pressure controlled ink jet printhead. The assembly includes an ink reservoir made of a first material having a first melting point and having an open top cavity defined by sidewalls, a bottom wall and a peripheral edge. A pressure control structure made of a polymeric material having a second melting point lower than the first melting point is included. The pressure control structure has a first surface, a second surface opposite the first surface, a side surface, and an aperture therein. A sealing structure for forming a liquid tight seal is provided between the sidewalls of the ink reservoir and the side surface of the pressure control structure. A pressure regulating film is attached over the aperture to the first surface of the pressure control structure. A cover is attached to the ink reservoir.
