Abstract: The disclosure of this invention relates to calorimeters and a process for operating a colorimeter. The colorimeter of the disclosure is controlled by a microprocessor which evaluates a predetermined radiation absorption curve for each sample. This is to be contrasted with the prior art wherein the test on a given sample evaluates only radiation absorption concentration points which are evaluated by the microprocessor. The colorimeter gives more accurate readings as a result of the fact that an absorption curve and its parameters are evaluated for each sample. The calorimeter uses multiple LEDs as a radiation source. The microprocessor further controls other functions of the colorimeter. A separate microprocessor may be used to control these other functions. The calorimeter and process of this invention are also useful in the analysis of samples for turbidity.

Abstract: This invention relates to a process for disease control in fish farming and more particularly, to a process whereby proliferative gill disease and other diseases and infections are eliminated by the treatment of a fish rearing pond or tank with low concentrations of Chloramine-T. The Chloramine-T is applied to the pond or tank and allowed to remain in the tank or pond until it breaks down. The concentration of the Chloramine-T can be from about 2 to about 3 PPM.

Abstract: The present invention is concerned with a process for the formation of dental restorations from glass-ceramic materials and the resulting dental restorations. In this invention, a dental restoration is prepared by placing a glass-ceramic material in a heat-pressure deformable crucible. Heat is then applied to the crucible in order to bring the glass-ceramic material to a working range at temperatures above its liquidus temperature. The crucible in which the glass-ceramic material is placed has heat-pressure deformation properties which are matched to the working temperature of the glass-ceramic materials being heated. The heat deformation properties of the crucible must be such that when the glass-ceramic material in the crucible is in the working range the crucible is heat-pressure deformable without rupturing.

The concentration of the Chloramine-T can be from about 0.5 to about 10 weight percent. The concentration of the wetting agent can be from about 0.1 to about 5%.

Abstract: A position indicator for a hydraulic jack plate for use with a marine outboard motor in a marine environment, the position indicator allows a boat operator to determine the position of an outboard motor relative to some fixed reference point usually the upper edge of the transom of a boat, the hydraulic jack plate has a fixed support and a moveable slide, a magnet is attached to the fixed support, this magnet activates individual segments of a multi segment transducer which is secured to the moveable slide of the jack plate when activated each segment of multi segment transducer produces a specific voltage which in turn activates a particular L.E.D., by observing which L.E.D. is activated an operator can determine the position of the slide and hence the position of the outboard motor, the light output of the L.E.D.'s is varied in relation to the ambient light.

Abstract: A process and apparatus for planting aquatic plants underwater on the bottom of estuaries whereby an aquatic plant which is ready for transplanting is positioned in a planting nipple having an angular groove in its upper portion. When the planting nipple is brought into contact with the estuary bottom, sea grass plants which are positioned on the angular groove, are planted on the estuary bottom. A plurality of planting nipples are incorporated on the periphery of a planting wheel. A watercraft is used to position the planting wheel with its planting nipples over an area to be planted is provided for. With the process and apparatus of this invention, sea grass plants can be planted on the bottom of an estuary in a semiautomated fashion.

Abstract: A process for planting aquatic plants underwater on the bottom of estuarys where an aquatic plant which is ready for transplanting is positioned in a holder having a device for retaining the transplantable plant and a thin base. When the holder is brought into contact with the underwater bottom the thin base engages the underwater bottom and secures the holder including the plant in underwater bottom. A watercraft having apparatus for positioning the holder incorporating the aquatic plant on the bottom of an estuary is also provided for. With this apparatus and the holder of this invention aquatic plants can be planted on the bottom of estuary in a semiautomated fashion. The holder also incorporates an organic buttom which retains the aquatic plant during the planting process.

Abstract: This invention is concerned with a panel device which is useful in the display and furniture arts, the panel device is formed from a plurality of panels which are securely locked into a three axis relationship with each other, the vertical edges of the individual panels incorporate undercut grooves, the vertical edges of the individual panels are provided with opposing locking lugs and a an elongated locking rod which retains the panels in relation to each other, the panel device may be readily converted from a set up to a flat stance for storage, in one embodiment at least the vertical edges of the individual display panels are provided with undercut H shaped channels that are secured in grooves that are routed into the edges of the panels, these H shaped channels further interact with the locking lugs and the elongated locking rod.
