A method of manufacturing blunt tip surgical needles. Taper point needles having conventional piercing tips are placed into a vessel containing a grinding media. The needles are maintained in the vessel for a sufficient amount of time to convert the piercing point into a blunt tip.

A process for removing silver from a silver containing photoprocessing solution, comprising the steps of: a) mixing a mercapto-s-triazine, or a water soluble salt thereof, with the solution thereby causing formation of a mixture of i) precipitates and fines of silver mercapto-s-triazine and ii) the solution; b) mixing a copolymer flocculant with the mixture thereby causing flocculation and agglome...

The interprocess communications subsystem (IPC) of the microkernel, manages the message passing operations for the communication of control information and data between tasks. Every message sent from a sending task to a destination, receiving task must use the IPC subsystem to manage its transmission. The separation of transmission control information from the data portion of the message allows th...

A method of etching a mirror for use in laser applications. A protective layer is formed on the mirror. The mirror is then masked to provide an etch region. The ?tch region is then etched using an eximer laser. After etching, the protective layer is removed.

A stored gas inflator is operable over a wide range of initial temperatures and such that the dependence of its total output as a function of initial temperature is substantially reduced. A vessel contains gas under pressure and has a seated outlet for the gas which is adapted to open upon command and permit passage of the gas therethrough. A thermal reservoir element is provided. A first exiting ...
