Abstract: A digital tone generator includes a modulo adder, an increment number register, two latches and a master clock. The adder continuously adds one of a plurality of predefined increment numbers with the adder's previously generated sums to create further sums and a carry output corresponding to one of a plurality of predetermined output tone frequencies. The system characteristics and increment numbers are selected to correspond to the predetermined frequencies and generate exact tonal frequency signals. The system characteristics and increment numbers are defined using a formula which accounts for the least common multiple of the rational number representation of the predetermined frequencies. In the preferred embodiment, the digital tone generator is used to select and generate one of a plurality of time code tones.

Abstract: An apparatus and method for cooling or heating fluids, such as fuel in a fuel system of an automotive vehicle. Compressed gas is delivered to a vortex tube or air amplifier 14 so that the gas rapidly expands and cools, thereby cooling a first end 16 of the vortex tube 14 in relation to a warmer second end thereof 18. A first fuel inlet port 20 of a first heat exchanger 16 lies proximate the first end 16 so that fuel flowing into the inlet port 20 is cooled by thermal contact with the first end 16 of the vortex tube 14. A cooled fuel outlet port 22 in the heat exchanger 16 lies proximate the first end 16 so that cooled fuel may leave the heat exchanger 16 for delivery to an engine. A valve with an upstream gate 26 and two downstream gates 28,30 is located so that fuel is selectively delivered to the first fuel inlet port 20 through the upstream gate 26 and one of the two downstream gates 28,30 if cooling of the fuel is desired.

The second drive mechanism has at least two finger bar drive modules coupled to the finger bar and spaced from each other lengthwise of the finger bar. A drive shaft extends between and interconnects the two drive modules. Each of the drive modules has a crank arm coupled to the drive shaft for rotating the crank arm about an axis parallel the finger bar. A cam plate is coupled to the finger bar and mounted for movement lateral to the crank arm axis and the finger bar.

Abstract: A method of forming dental products, such as dentures, denture relines, dental crowns, dental bridges and dental restorative materials, temporary crown, temporary bridge, provisional crown or provisional bridge, from two polymerizable paste compositions each having a complimentary component of a free radical catalyst system and a polymerizable acrylic compound. One of these paste compositions includes an oxidizing agent and a stabilizer and the other includes a reducing agent as components of a redox catalyst system for free radical polymerization. These paste compositions are mixed in a static mixer to form a polymerizing paste composition, which is then shaped into a dental prosthesis. A handheld mixing dispenser useful in carrying out this method, includes a static mixing conduit, and two containers enclosing the polymerizable paste compositions. The static mixing conduit encloses a static mixing member. The containers are adapted to be connected in fluid flow communication with the static mixing conduit.

Abstract: A method of preparing an impression of dentition in the oral cavity is provided that overcomes a problem of transfer of inhibitors left by latex gloves that interfere with platinum catalyzed hydrosilation reactions. The method involves applying a surfactant, preferably with peroxide, to the area that is to have its impression taken substantially immediately before applying the impression taking material, rinsing the composition from the area and proceeding with the taking of the dental impression. Preferably the decontaminating composition consists essentially of surfactant, especially polyoxyethylene surfactants, hydrogen peroxide and water.

Abstract: Human interferon-beta.sub.2.sbsb.A and interferon-beta.sub.2.sbsb.B are produced in purified form by recombinant DNA techniques. Two separate human genes have been identified which code for the production of IFN-.beta..sub.2.sbsb.A and IFN-.beta..sub.2.sbsb.B, respectively. The sequence of IFN-.beta..sub.2.sbsb.A cDNA is established. These genes and cDNA have been cloned into mammalian cells with an SV40 early promoter sequence and such genomic clones are capable of producing IFN-.beta..sub.2.sbsb.A and IFN-.beta..sub.2.sbsb.B. The antiviral activity of such recombinant IFN-.beta..sub.2.sbsb.A and IFN-.beta..sub.2.sbsb.B is demonstrated as well as other biological activity identifying them as human interferons.

Abstract: Disclosed herein are genetic markers for pig litter size, methods for identifying such markers, and methods of screening pigs to determine those more likely to produce larger litters and preferably selecting those pigs for future breeding purposes based on the ESR polymorphisms. The markers are based upon the presence or absence of certain polymorphisms in the pig estrogen receptor gene. Preferably, the polymorphism is a restriction fragment length polymorphism (RFLP).

Abstract: Reliable and cost effective testing for mutations in the RB1 gene can be accomplished by quantitatively amplifying exons of the sample RB1 gene using primers complementary to intron regions flanking each exon; and then determining the lengths and/or quantities of the amplification products for each exon and comparing that length or quantity to the length or quantity of amplification products obtained when a wild-type RB1 gene is amplified using the same primers. Differences in length between an amplified sample exon and the corresponding amplified wild-type exon reflect the occurrence of an insertion or deletion mutation in the sample RB1 gene. Differences in quantity reflect the complete absence of an exon, or heterozygosity for a mutant exon. Next, the nucleic acid sequence of each exon found to contain an insertion or deletion mutation is determined, or of all exons in the event no insertion or deletion mutations are identified.

Abstract: A rocket (100) is disclosed having a body (101) with a bay (102) therein and a hatch (109) which is movable between a bay opened position and a bay closed position by a spring biased hinge (110). The hatch is pivotally coupled to a nose section (104) by a spring biased hinge (11). The hatch is configured to be engaged and disengaged with a catch (118) mounted to the rocket body. With the initial forward movement of the launched rocket the inertia and/or the force of the wind upon the nose section causes the disengagement of the catch whereby the continued movement of the rocket creates a wind upon the nose section which maintains the hatch in its bay closed position.
