Title: Needle device and method of operation thereof
Inventor: YIGAL GIL
IPC: A61M5/46
Filed: 2001-06-29
Abstract: A needle device has a needle retraction mechanism that retracts the needle upon removing the device from the skin surface (either intentionally or unintentionally). Once the needle is retracted, the device is rendered inoperative. The needle can be further made inoperative by bending it when one attempts to reuse the device. In another embodiment, a needle opening formed in the base of the housing can be covered to render the needle inoperative when one attempts to reuse the device. In another embodiment, a needle device instead has a needle shield that automatically covers the needle after use.

IPC: A61K9/70
Filed: 2001-11-16
Abstract: A transdermal medicament delivery device in the form of a printed temporary tattoo (2) which conceals the fact that the wearer is taking a drug. The ornamental appearance actually provides an incentive for wear. The medicated  tattoo (2) includes a section of cardstock base paper (70), a clear base (50 ) bearing an ink design on one side, the clear base being attached to the cardstock base paper (70) on the other side by a release base (60) that dissolves when wet to allow detachment of the base paper, and an adhesive layer (20) coated over the ink design on the clear base for adhesion to the skin. A medicament or drug (30) is incorporated into the adhesive layer for diffusion therefrom into the skin of the wearer, and the adhesive layer (20)  has predetermined permeability characteristics to ensure effective transderm al delivery of the medicament (30). The process for making the transdermal tattoos includes lithographic printing and silk screen coating to create the  necessary layers, inclusive of drug deposition on the control membrane. Th n et result is less susceptible to being dislodged, thereby allowing more conventional low-strength skin adhesives to make intentional removal easy an d painless. Moreover, the tattoo can provide an outward visual indication of t he progress of delivery.

Title: Rejuvenation of refractory metal products
Inventor: UHLENHUT HENNING
IPC: B22F3/24
Filed: 2002-02-14
Abstract: Refractory metal products (12), such as tantalum on non-refractory conductive metal backings (14), e.g. copper, can be rejuvenated after metal consumption in selected zones by powder filling (28) the zones (18) and high energy heating (30) at high scan speed to sinter the added powder, without complete melting of the powder fill, thus establishing a microstructure consistent with the balance of the reclaimed product and avoiding the separation of the copper backing (14) and tantalum sputter plate (12). The rejuvenation method can be applied to non-mounted refractory metal products that are subject to non-uniform erosion, etching, chipping or other metal loss. The form of such refractory metal products can be as plate, rod, cylinder, block or other forms apart from sputter targets. The process can be applied to, for example, x-ray disks or targets (molybdenum plate on carbon backing).
