The present invention utilizes the unique addition of mischmetal to aluminum base alloys to either enhance the conductivity of such alloys when compared to commercial conductor grade material or provide equivalent conductivity when utilizing grades of aluminum containing higher normal impurity levels. Various processing procedures can be utilized for this material, depending upon the desired final properties.

A copper base alloy is disclosed which exhibits improved resistance to crack propagation during hot processing as well as good mechanical properties. The alloy comprises from about 4.0 to about 11.0% tin, from about 0.01 to about 0.3% phosphorus, from about 1.0 to about 5.0% of a material selected from the group consisting of iron and a mixture of iron and cobalt, up to about 0.4% chromium, balance essentially copper. The alloy of the present invention possesses a substantially non-dendritic grain structure in the cast condition which contributes to said resistance to crack propagation.

Brazing preforms are disclosed which may take the form of wire, sheet or strip, and which are useful for joining copper, ferrous and nickel base alloys. The preforms of this invention are prepared from an alloy which contains manganese from 22 to 40%, iron from 0.1 to 2%, aluminum from 0.1 to 5%, zinc from 2 to 10%, balance essentially copper. A method of brazing is also disclosed which may be performed with or without a flux, and which is conducted in an inert atmosphere, at a temperature of from about 900.degree. to 1100.degree.C. The brazed products of this invention possess reduced brittleness and improved resistance to corrosion.
摘要:
A method of billing is disclosed comprising the steps of the server billing at least one treatment for a client by a device by means of a billing unit, a treatment computer in communication with the device requesting access of the device using an access code, the device granting access for a treatment if the access code is valid and blocking access if the access code is not valid, and treating the client using the device when access to the device is granted. Further disclosed is a method of billing comprising the steps of a service provider locating a device at a clinic, the clinic providing a treatment to a client, the clinic billing a payer, the payer paying a treatment fee to the clinic, and the clinic paying a subset of the treatment fee to the service provider.
摘要:
A business method provides access to digital medical image data generated by up to a plurality of imaging facilities to a payer. The business method includes receiving digital medical image data generated by the imaging facilities using a gateway at each imaging facility. The received-digital medical image data is transmitted from the gateway to a central server via a network and stored at the central server. The payer is then provided access to the stored digital medical image data via the network for a fee.
摘要:
A process for providing copper base alloys with a combination of high strength and high strength to ductility characteristics is disclosed. The alloys should be those copper alloys which exhibit continuous, homogeneous precipitation of coherent particles such as spinodal decomposition upon precipitation hardening. The alloys are hot worked, solution annealed and subjected to a controlled cooling to provide the desirable strength-ductility combinations.
