US Patent:

6356080, Mar 12, 2002

Filed:

Sep 28, 1999

Appl. No.:

09/406351

Inventors:

James Maurice Daniels - Princeton Junction NJ 08550-1231

International Classification:

G01V 300

US Classification:

324313, 324309, 324318, 324322

Abstract:

A device for measuring the polarization of a hyperpolarized resonant substance; in a particular embodiment a hyperpolarized noble gas. A specimen of the hyperpolarized substance is made one component of a coupled oscillator, the other component being a resonant electric circuit. Such a coupled system has, in general, two stable modes of oscillation, and their frequencies are related to various parameters of the system, including the polarization of the specimen of hyperpolarized substance. The polarization can therefore be deduced from these frequencies.

International Classification:

G01J 400

US Classification:

356369

Abstract:

This device makes measurements of the intensity of light in four different polarizations, chosen for maximum accuracy and efficiency. In the âmeasuring headâ the light passes through two liquid crystal waveplates and a polarizing filter before falling on a light sensitive element. Different interchangeable measuring heads, using this principle, can be made for different applications. The device has electronic control and display circuits, coordinated by a microprocessor. With a photodiode as the light sensitive element, the device is a portable stand alone polarimeter which displays the polarization parameters in whatever representation the operator chooses. With a digital camera as the light sensitive element, the device produces four scenes which can be processed digitally and uploaded as a scene seen in any arbitrary polarization. Also, the unpolarized component can be filtered out; something impossible with physical filters placed before the lens.

James Maurice Daniels - Princeton Junction NJ, US

International Classification:

G01V 3/00

US Classification:

324313, 324317

Abstract:

This invention concerns a new embodiment of the instrument to measure nuclear polarization described in U. S. Pat. No. 6,356,080. The coil, that couples the nuclear polarized substance to the electronics, has been designed not to pick up ambient electromagnetic noise. The output from the low level oscillator is passed through a Schmidt trigger to reduce noise. A local oscillator beats with the output of the low level oscillator to provide an audible output. The instrument is automated, using a microprocessor with a customized downloaded program, to control the operation of the instrument and to output the results of measurement to a liquid crystal display and, if desired, to an external computer. This computer is not necessary and the instrument can act as a stand alone.

Appl. No.:

6/543721

Inventors:

James H. Daniels - North Wales PA

Assignee:

General Signal Corporation - Stamford CT

International Classification:

F01K 1302

US Classification:

290 40B

Abstract:

This invention provides for regulating the generation of a generator at a local power station whose governor receives control signals from a central load dispatcher effective to change the generation so long as there is a change in generation required to meet desired system conditions and wherein a signal representative of actual generation of the generator is fed back to the load dispatchers office. The improvement provides means for producing a signal representative of the ratio of the throttle pressure set point to the actual throttle pressure as well as means for multiplying the signal representative of actual generation by that ratio and supplying the product as the sole feedback to the load dispatcher for determining the control signals to the governor.

International Classification:

H05B 680

US Classification:

Abstract:

A method and package assembly for retailing and microwave heating of a breaded food product is provided. The package assembly includes a container with an interior surface composed of a microwave interactive material. The container bottom has inlet air openings and the container top has outlet air openings therein. The container also has a support member for supporting the food product in order to minimize the degree of contact between the food product and the container and the support member. The container is adapted to rest on an exterior packaging sleeve whereby a generally verticle air flow pathway is provided through the container to promote convection heating and crisping of the breaded surface portion of the food product during microwave heating.
