Abstract: Adding a small quantity of a violet colorant to a contact lens material provides a clear contact lens that has no apparent undesirable yellow tint such as caused by a UV-absorbing compound. Further, the violet colorant can also be used with a colored lens, in the absence of the handling tint, to mask any undesirable yellow tint, such as that produced by a UV-absorbing compound. The violet colorant will not unacceptably alter the modifying color of the colored lens.

Abstract: An ink jet printhead has a body of PZT (13') bonded to a base plate (13"). Channels cut in the PZT form ink chambers which are actuated by applying voltages to electrodes on surfaces of the cham-bers. The base plate also carries IC's which contain the drive cir-cuitry for actuating the ink cham-bers. To ensure reliable electrical interconnection between the cham-ber electrodes and the IC's, the electrodes (190', 190") and con-ducting tracks (192', 192") on the base plate are formed in a sin-gle step by depositing a conductive layer over both the PZT body and the base plate. The necessary pat-tern of electrodes and tracks can be achieved by masking or by selec-tive material of conductive mate-rial.

IPC: A61M5/32
Filed: 2001-08-03
Granted: 2009-02-24
Abstract: A hypodermic syringe with a selectively retractable includes an barrel having an proximal end and a distal end that defines a receiver with a shoulder. The barrel has a hollow bore therethrough and the receiver includes a plurality of inwardly projecting cams distal to the shoulder. There is an elongate plunger with a proximal end and a distal end sized to fit slidably within the bore of the barrel to define a chamber. There is a hub with a flange and a stem that has a passageway therethrough extending distally into the receiver. The stem has distal recesses disposed to engage the projecting cams so that the hub is retained with the distal end of the stem in the receiver. The syringe includes a needle mounted in the passageway in the hub with the distal point projecting distally and the fluid path communicates with the chamber. There is a clip about the elongate plunger initially allowing movement of the plunger for drawing and expelling fluid. When sufficient distal force is applied to the plunger moving and rotates the hub, the clip engages the barrel permitting only proximal movement of the plunger. The syringe includes a spring disposed about the stem compressed between the flange and the inward shoulder. When sufficient distal force is applied to the flange the hub is no longer retained. The spring urges a proximal movement into the barrel as the plunger is moved proximally.
