Title: Apparatus and method for controlling distribution of electrical energy to a space conditioning load
Inventor: MASSARA JAMES M
IPC: G05D23/19
Filed: 1995-01-26
Abstract: An apparatus and method for controlling energy supplied to a space conditioning load and for overriding a load control operation in response to measuring certain space temperatures within a closed environment. The load control apparatus includes a control device connected to an electrical distribution network and to a space conditioning load and a temperature sensing device connected to the control device. The control device conducts a load shedding operation to control distribution of electrical energy to the space conditioning load in response to command signals supplied by a remote command center. The temperature sensing device operates to override the load shedding operation by outputting a control override signal to the control device in response to sensing certain space temperatures within the closed environment. If the temperature control device is connected to an air conditioning system, the temperature sensing device causes the control device to terminate the load shedding operation prior to expiration of a selected time period in response to measuring a space temperature that exceeds a maximum space temperature limit. In contrast, if the temperature control device is connected to a forced air heating system, the temperature sensing device causes the control device to terminate the load shedding operation when a measured space temperature drops below a minimum space temperature limit. The maximum space temperature limit is greater than the control temperature setpoint of a thermostat that controls the space conditioning operations, whereas the minimum space temperature limit is less than the control temperature setpoint.

Title: Astragalus polysaccharide immunomodulators
Inventor: VERBISCAR ANTHONY J
IPC: C08B37/00
Filed: 1992-08-24
Abstract: Polysaccharides from the gum exudates of Astragalus species Tragacantha section plants are extracted, separated and modified into water-soluble forms free of small molecular impurities. The purified polysaccharide forms are immunomodulators which inhibit cancer cells and viruses, and can be used to treat immunologically defective disease states. The polysaccharide-homogeneous products from different Astragalus species exhibit the same kind of immunomodulatory activity in different mammalian systems, but differ in potency. The purified polysaccharide forms of these GRAS gum tragacanth products show no toxicity on parenteral administration.

Title: Electronically controlled beverage dispenser
Inventor: BETHUY TIMOTHY W
IPC: B67D1/00
Filed: 1995-05-01
Abstract: An electronic control for the operation of a beverage dispenser of the refrigerated ice bank type is shown. The control provides for reliable determinations of when ice production is needed and when it is not needed. A microprocessor receives information from an ice bank probe and from a temperature probe located within the ice bank. Data collected by the microprocessor from both the ice bank probe and the temperature probe is used to determine if the ice bank is either insufficient in size and should be increased or is of sufficient size such that the compressor can be turned off. A carbonator level probe is also shown and connected to the microprocessor. The microprocessor is programmed whereby the carbonator probes are sampled in a manner to accurately determine the level of water in the carbonator and therefore the need for turning on or turning off any water pump connected thereto Both the operation of the compressor and the water pump are controlled by the microprocessor wherein the programming thereof provides for adequate hysteresis protection so that short cycling of the compressor and water pump is avoided.

Title: Inspection of transparent containers
Inventor: GERBER STEPHEN M
IPC: G06T1/00
Filed: 1995-08-14
Abstract: Apparatus for inspecting transparent containers having sidewall portions of differing optical properties that includes a pair of discrete light sources for directing light energy through the adjacent essentially discrete portions of the containers having the differing optical properties.  A camera receives light energy directed through the container from both of the light sources as a single image of the entire portion of the container illuminated by both light sources. Commercial variations are detected as a function of variations in light intensity at the camera.  The camera includes an array sensor that receives light energy transmitted through both of the container portions, and is scanned at increments of container rotation so as to develop an electronic image of the entire portion of the container illuminated by the light sources. The light sources are coordinated with the imaging electronics such that the electronic image has uniform optical properties in all portions of the image in the absence of commercial variations at the container.

Inventor: LEE RON C
IPC: F17C9/00
Filed: 1996-04-04
Abstract: A cryogen delivery apparatus for delivering cryogen in a saturated state includes a vessel to contain the cryogen in liquid and vapor phases.  The vessel has a headspace region and a heat exchanger  located within the headspace region for indirectly exchanging heat between the vapor located within the headspace region and a liquid stream composed of the liquid phase of the cryogen.  In case the cryogen is introduced into the vessel as a subcooled liquid, the vapor will condense into the liquid phase and the subcooled liquid will be converted into a saturated liquid.  The saturated liquid will then be discharged from a liquid outlet connected to the heat exchanger.  In the event the liquid enters the vessel as two-phase flow, the vessel will act as a phase separator.  A branched supply line is provided having a liquid inlet branch connected to a bottom liquid inlet of the vessel so that a supply stream composed of  the cryogen flows into the vessel. A vapor inlet branch of the branched supply line is connected to an inlet to the headspace.  A heating element is provided to heat the vapor inlet branch so that liquid cryogen is vaporized to replenish vapor within the headspace that is depleted through condensation or discharge from a vapor discharge outlet of the vessel.
