Abstract: An electronic automated scorekeeper for calculation and recordation of athletic contest statistics. An operator enters data into the device via a keyboard with a plurality of specialized keys. One set of the keys located on a graphic of the playing field, corresponds to the positions of the players in the contest, such as the field positions of baseball players. Another set of the keys is dedicated to one step entry of common events during the contest. Other keys provide control functions and alpha-numeric entry. At the start of the contest, the operator enters data about the players and the teams. As the contest is contested, the operator enters events as they occur. The automated scorekeeper records the data entered and calculates the progress of the game and the player statistics as they occur. The device provides for a printed output of the game in progress, for periodic statistical summaries and for a final game and player statistical output.

Abstract: A scale modelling centrifuge has a relatively massive rotary circular base wall, which may form part of a drum, possibly with a detachable peripheral wall either carrying an annular sample-reciving trough or constituted by such trough, or which may have mounted therearound a plurality of sample-receiving containers.

Abstract: An apparatus which attaches to the outer rim area or bottom surface area of an x-ray cassette holder used to support the x-ray cassette upright (parallel to or with the top surface of the holder) and next to the edge of a resting table or surface. The apparatus allows this particular type of cassette holder to rest the entire holder on top of a table and have the holder even, level or horizontal with the table top while the holder's slot supports the x-ray cassette upright perpendicular to the table top. The apparatus adjusts the holder into proper alignment so that the top of the slot and the top surface of the holder (including the outer edge or rim area) are even and horizontal to the top of the table.

Abstract: A tuner for radio frequency coaxial cable transmission lines is provided. It requires only one micrometer adjusting screw since the capacitor electrode that mates with the central conductor of the coaxial line is not only curved to give a large area in proximity to the central conductor but is rectangular and much longer than the diameter of the micrometer screw.

Abstract: An improved process is disclosed for producing a unique metals-containing anisotropic pitch suitable for carbon fiber manufacture. Soluble, aromatic-organometallic compounds are added to a carbonaceous feedstock which is substantially free of mesophase pitch and the resulting composition is heat soaked to produce an isotropic pitch product containing mesogens and soluble, aromatic-organometallic compounds. Next, the pitch product is solvent fractionated to separate mesogens which contain metals from the organometallic compounds. The metals-containing mesogens are heated to a temperature sufficient to cause fusion to produce a metals-containing mesophase pitch.In another method, the carbonaceous feedstock is heat soaked to produce an isotropic pitch product containing mesogens and high molecular weight, soluble, aromatic-organometallic compounds are added to the mesogen containing isotropic pitch product prior to solvent fractionation.

Abstract: This PMDC machine concept operates from a constant dc voltage source with maximum torque capacity throughout its rotational speed range. The back electromotive force (back-emf) produced by the machine windings under the constant amplitude air gap field produced by the magnets is controlled by changing the winding configurations in series-parallel combinations. Torque is, thus, controlled from minimum to maximum speed without exceeding winding current capacities and without need to increase driving voltage with speed. At startup and low speed the combined back-emf of series connected windings limit current while producing maximum torque. At higher speeds where back-emf would severely limit torque, the windings are connected in series-parallel combinations for maximum achievable torque without exceeding winding current capacities. To accomplish this, windings concentrated in slots are used. Result is optimum utilization of core magnetics and capability of operating at constant input voltage.

Abstract: A device for monitoring medication of a patient and for prompting the patient into certain medication taking schedule and/or certain programming steps and routines. The device has a plurality of compartments, each of which may store medication, and an electrical signaling system to emit medication alert signals from time-to-time, each of which said signals indicates (a) that medication should be taken, (b) from which compartment the medication should be taken, (c) and the quantity of medication to be taken. If a designated compartment is not opened and closed within a predetermined period of time, the electrical signaling system will display an alarm and the event will be recorded as a missed medication event, unless the patient then opens the designated compartment. If each designated compartment is opened and closed, the take-medication signal and the alarm (if operating) are turned off and the event is recorded for later review.

Abstract: The oil is separated from the rainwater that runs off of a parking lot or off of the pavement of a filling station. An inlet tank receives the runoff water. When the water is entering that tank at a very low rate, the surface water and/or oil in the inlet tank drains to a main separation tank where the oil floats on clean water. That clean water is fed to an outlet conduit that feeds unpolluted water to the city sewer or to a river. When the inlet flow increases to an intermediate rate, a pipe of inverted L-shape feeds clean water from the inlet tank to the outlet conduit. When the inlet fluid has a very large flow rate, as might occur during a heavy downpour of rain, the fluid level in the inlet tank rises to a level at which there is a direct overflow into the outlet conduit.

Abstract: Foam forms for use in making a concrete wall are disclosed together with a method of making the forms. The forms are stackable to form a cavity that receives the concrete. Each form has two identical panels. The panels are molded separately by first placing a structure, consisting of backing plates that will be along one side of the mold, connecting members that will be along the opposite side of the mold and an apparatus that connects the backing plates to the connecting members, in the mold. The mold is then filled with foam which cures and produces a panel with the backing plates, connecting members and apparatus molded into the panel. The molded panels are then shipped to the job site where the forms are assembled. Each form is assembled as follows: The connecting members on one panel are interconnected, by tieing means, to the connecting members on a second panel to provide a form.

Abstract: A computer is provided for calculating input data for an X-ray machine which is about to be used for making an X-ray of a body part. The computer has a multiplicity of input devices each dedicated to inputting particular information that should enter into the input information for an X-ray machine including a series of input devices each dedicated to one pathological disease that the body to be X-rayed may have, input devices dedicated to particular body parts, and an input device dedicated to body part thickness. A program causes the computer to compute the input data for the X-ray machine based on the information fed to the computer via the input devices.

Abstract: Powdered and liquid fluid loss additives are disclosed for use in cementing wellbores, particularly oil and gas wellbores. Excellent fluid loss control is achieved over a wide range of conditions using various cements systems. The invention utilizes polyvinyl acetate polymers as a fluid loss additive. The polyvinyl acetate polymer is used in conjunction with a dispersing sulfonated polymer and surfactant. This highly effective combination is then adjusted to individual well conditions with chelating agent, cross-linking agent, biocides, antifoams, or combinations of these. The dispersants are novel dispersing agent polymers such as melamine sulfonate polymer, vinyl sulfonate polymer and styrene sulfonate polymer and mixtures of these. These dispersant materials are usually prepared at low pH and can be used in the acid form, or neutralized to form salts of the polymers, wherein the salt can be a Group I or Group II metal salt, or ammonium salts (common salts).

Abstract: The present invention provides a process and apparatus for collecting relatively straight blow spun fibers in a two dimensional configuration. The process utilizes a venturi to preclude the kinking and bending of the fibers until the fibers have substantially thermoset. A diffusion chamber allows the fibers to be collected without entangling.

Abstract: The present invention monitors the disease process and health of a patient undergoing drug treatment. A microprocessor-based medication dispenser provides for recording a variety of clinical information data; such as illness symptoms, side effects, general health ratings, adverse drug interactions, illness attitudes, and lifestyle habits at various times during a drug delivery cycle. The date and time of entry of the specific clinical information is entered, and correlated with the date and time when the patient has taken or missed a particular medication. The effects of the presumptive blood levels of one or more medications can then be assessed, as to their impact on the disease process, and any additional effects on the body. The device can analyze the data and display a response to it, or download the data into another device. The second device can analyze the data, and upload new information into the first device, to tell the patient to alter his or her behavior in taking medication.

Abstract: An apparatus and method for determining the presence of dissolved gas in a fluid under pressure. A test cell capable of containing the pressurized fluid has a test instrument disposed therein. The test instrument has two platinum leads connected by a sensor element. The platinum leads are connected to an external source of electrical power. A thermocouple is mounted in the test instrument. The apparatus is calibrated using degassed, demineralized fluid at a known pressure by applying power to the platinum leads in a stepwise manner and recording the resistance of the sensor element versus applied power. The test cell is connected to fluid suspected of having gas dissolved therein and power is applied in a stepwise manner to the platinum leads. The power applied versus the resistance of the sensor element is recorded. A comparison between the power versus resistance for the degassed fluid and the suspect fluid discloses the presence of dissolved gas.

Abstract: This invention describes a dual mode optical switching device comprising organic quantum well regions interfacing with inorganic semiconductors. Each mode generates excitons and a photocurrent in their respective quantum well regions in response to incident control beams of different wavelengths of light. The photocurrents in each mode independently modulate the transmission of the lower frequency signal beams. Multiple hybrid organic/inorganic quantum well optical devices can be crafted into optical logic gates by using light impulses in a manner that is analogous to the way electronic gates are used in electronic systems. These devices can also perform as optical switches and optical interconnects between electronic elements. Thus the processing units are electronic and the connections between them are optical, comprising optoelectronic system with higher data throughput that will exceed electronic systems.

Abstract: This invention relates to a friction drive that uses two straight sided cones, the apexes of which are located at a common point. A driving or driven roller is located between the two cones so that rotation of this roller causes (or is caused by) the rotation of the cones. The rotary axis of the roller passes through the point at the apexes of the cones. In this manner the roller element in contact with the surfaces of the cones becomes an element of a cone rolling correctly on the two cones without experiencing any spin. The use of two cones balances the forces on the roller and doubles the torque that can be transmitted between the roller and the cones. A different embodiment of the invention uses two or more rollers contacting the two cones. By changing the position of the rollers it is possible to obtain a very large speed ratio between the rollers.
