An identification combination comprising a band adapted to be fitted about the wrist, leg, neck or the like of a patient or about an object and further including a tether strap attached to or adapted to be attached to an encodable identification device and to the band so that the identification device can be held away from the patient for transfer of information therefrom without removing the identification device from the patient.

Apparatus and methods for providing patterns of materials, as for color printing. A support member (30) has groups of surface areas (40A,40B, etc.) with each surface area in a given group (e.g. 40A) facing generally in a direction different from that faced by the surface areas in any other group (e.g. 40B, etc.), and an energy-modifiable material (41A,41B, etc.) adjacent to the surface areas in each group. Energy (A,B,C) is directed onto the material adjacent to the surface areas in each group i…

Apparatus and methods for use with electronic activation means such as work or entertainment systems introduce precisely controlled amounts of aromatic chemicals, using metered spray technology, into the immediate vicinity of the operator. Control is provided by microprocessor circuitry so that aromas may be used at appropriate times and intensities by computer or entertainment sources. Multiple removable spray containers may generate numerous aromatic enhancements to a wide variety of applicati…

A method for providing a barrier against copper diffusion into a zirconium alloy tube which is lined with copper for the purpose of increasing the resistance of the tube to stress corrosion induced by fission products when the tube is used to fuel a nuclear reactor. The method involves the deposition of a copper lining on the zirconium alloy tube and the subsequent exposure of the lined tube to a substance such as steam, water, nickel oxide or carbon dioxide or another material which has the abi…

The refrigeration available in a liquefied gas is utilized to refrigerate a fluid having a boiling point above the boiling point of the liquefied gas which is sprayed into an endless conduit such that the liquefied gas is vaporized. The resulting thermal currents and momentum of the spray are effective to provide the motive power for circulating the gas throughout the conduit and into indirect heat exchange with the fluid to be refrigerated. The temperature of heat exchange means in the vicinity…

By blocking part of a spinnerette orifice with a wire strand desirable cross-sectional shaped fibers of acrylonitrile polymer are obtained.

A composition comprising negatively doped hot pressed particulate silicon carbide, the process for making the composition, an electrical hot surface fuel ignitor manufactured from the composition, a silicon brazed electrical connection for the ignitor and an ignitor circuit containing a dropping resistance.

In a process for improving the strength characteristics of a wire composed of an austenitic metal alloy selected from the group consisting of stainless steel alloys of the AISI 200 and 300 series and non-stainless steel alloys containing iron, manganese, chromium, and carbon, comprising the following steps: (a) deforming the wire at a strain of at least about 10 percent and at a temperataure in the range of about Md minus 50.degree. C. to about Md plus 50.degree. C., (b) cooling the wire to a te…

A method of providing a structural shape includes starting with waste paper and treating the waste paper in a hammer mill to produce paper fibers. The fibers are put through a screen. The screened fibers are mixed with a binder such as a thermosetting epoxy foaming resin or with a phenolic resin in water in preferred proportions. The water or other solvent is kept to a very small value to provide a relatively dry process. The mixture is then pressed in a geometrical shape under substantial press…

An Indicia bearing disc of flexible plastic mounted and juxtaposed to a transparent mating solid disc rotated to provide rigidity to the flexible disc and method of projecting light onto the indicia for photocomposition.
