Abstract: The phoP gene and its equivalents are of a type which have "global regulation of pathogenicity", i.e., they coordinately regulate a number of genes including those that encode bacterial virulence factors. In Salmonella, the phoP gene product also controls the expression of non-specific acid phosphatase from the phoN gene. A central feature of the invention are microorganisms which are avirulent as a result, in whole or in part, of a mutation in phoP, but which retain their immunogenicity. These cells are suitable as components of live vaccines.

Abstract: A diagnostic assay for detecting the presence of an infectious herpes virus in a specimen and a genetically engineered cell line for use in such assay are disclosed. The cell line used in the assay expresses a reporter gene only if infectious herpes virus is present in the specimen. The assay involves inoculating a DNA-transfected cell line with a specimen suspected of containing a herpes virus, allowing a sufficient period of time for the herpes virus infectious cycle to proceed, and detecting and quantifying the number of herpes virus-infected cells to determine the number of infectious herpes virus virions in the specimen. The cell line is a DNA-transfected cell line susceptible to infection by a herpes virus which is stably transformed with a chimeric gene comprising a herpes virus inducible promoter and a gene coding for an enzyme, the expression of the enzyme being dependent upon and quantitatively proportional to the presence of herpes virus. A kit for such assay is also provided.

Abstract: The present invention pertains to a document sheet or a business form formed as a single sheet or part of a continuous web of interconnected sheets where an indentation is pressed into a front surface of the sheet and an object such as a card, label or coin is releasably adhered to the sheet in the indentation, whereby recessing the object in the sheet indentation enables the simultaneous printing of both the document sheet and object.

Abstract: A deflection coil is formed into a saddle shape by winding up a conductive wire ribbon in layers, such that the layered wire ribbon is formed in its cross-section into a parallelogram with adjoining sides crossing one another at other than 90 degrees. The deflection coil is produced by winding up in layers the wire ribbon in a plurality of coil grooves of a coil-winding frame die while the wire ribbon is delivered out from a nozzle, obliquely against the side wall face of each coil groove.

Abstract: A structural graphic display has one or more first generally transparent surfaces with reversed images superposed thereon juxtaposed to a reflective surface such that the reversed image may be viewed as a reflection in the reflective surface. The display may be either purely an ornamental device, or may be utilized in lamps, desk accessories, greeting cards, or clocks as disclosed herein.

Abstract: A method for preparation of a pasta-based food product is disclosed. The method comprises several steps. Pieces of pasta are cooked to form pieces of cooked pasta. The cooked pasta is mixed with a binding composition comprising a binding agent that is either soy protein, or an egg white composition consisting of either egg whites or a mixture of powdered egg white and water. The pasta and binding agent are mixed in a cooked pasta to binding agent weight ratio of from about 40:1 to about 10:1, to form a pasta/egg white mixture. A desired amount of the mixture is formed into a desired shape and the desired shape of mixture is baked until the pieces of cooked pasta adhere together, yet remain moist. A pasta-based food product prepared by such method is also disclosed.

Abstract: An aqueous short term residual dust suppressant is disclosed. The suppressant comprises from about 50 parts by weight to about 2,000 parts by weight water per part by weight of a combination of an anionic foamer and a nonionic or anionic wetter in a foamer to wetter weight ratio of from about 1:1 to about 1:20. Pre-mix concentrates and methods for dust suppression with such suppressants are also disclosed.

Abstract: A method and apparatus is disclosed for using the remanent noise of a magnetic medium as a fingerprint for benchmark testing of the magnetic medium as it is both manufactured and used. A cross-correlation is made between the fingerprint at various times as the magnetic medium is manipulated and is indicative of the integrity thereof. This cross-correlation media may be used to control manufacturing and recording processes, including tape tensioning and channel equalization. This cross-correlation between fingerprints can be used to control the tension applied to a thin film magnetic medium during record and/or playback.

Abstract: The present invention provides a clothes hanger rod attachment to be used in combination with wire shelves so as to allow uninterrupted slidability of clothes hangers while retaining strength, durability, low cost, and ease of manufacture. The attachment may be readily used in conjunction with existing wide web and narrow web wire shelving configurations.

Abstract: The integrity (density) of discrete pieces of hard tissue (bones) in a patient may be determined by either one of two methods. In a first method, an impulse of energy is introduced into the hard tissue, such as by striking the patient's hard tissue, and the induced vibration is sensed and analyzed in order to compute the damping factor thereof, the damping factor being directly related to the density thereof. With this method, a transducer is coupled to the hard tissue and its output is amplified by an amplifier before input to a computer which determines the damping factor. In a second method, a continuous energy input is provided to the hard tissue, such as by utilizing a frequency generator coupled to a power amplifier whose output drives a transducer such as a speaker or the like for inducing a continuous vibration in the hard tissue. This continuous vibration is measured with a transducer, having amplified output, and a damping factor is calculated with a computer.

Abstract: An automatic control for a pellet mill includes a method for automatically calculating start values for feeder speed and steam valve position upon start-up of the pellet mill for pelleting particular formulas of feed. The method includes the step of monitoring the pellet mill to determine optimal feeder speed and steam valve position when the mill is running at optimal conditions, and then adjusting these values by a fixed percentage in order to determine the start-up values. As the steam valve is non-linear, another method is disclosed for converting the steam valve position to a corresponding steam flow, multiplying the optimal steam flow by the same fixed percentage, and then reconverting the starting steam flow value to a corresponding steam valve position. The fixed percentage used to determine the start values may be adjusted, depending upon how aggressive the operator desires the start-up to be and perhaps to adjust for differences in pellet formulations.

Abstract: A coil-winding frame body for deflection yoke coil, includes: a straight portion formed as a neck side; a trumpet-shaped curved surface portion spreading outward from the end of the straight portion toward a head side; and a plurality of flanges formed on the inner face of the body for defining a plurality of coil-winding grooves and walls, and each of the grooves is elongated from the neck side to the head side and into which a wire ribbon will be wound in layers.

Abstract: A model simulating cochlear spectrum analysis is disclosed which includes a pair of matched all pole lattices interconnected by a plurality of tip couplers providing non-linear distributed bilateral signal processing. One of the lattices along with the tip couplers corresponds to the organ of Corti found in the cochlea and the second lattice corresponds to the basilar membrane also found in the cochlea such that the model provides a striking resemblance in structure to the physical properties of the cochlea itself. With the cochlea model disclosed, distortion products and otoacoustic emissions are simulated. An intermediate model is also disclosed which provides bilateral signal processing but lacks distributed amplification.

Abstract: Multicasting is implemented in a virtual circuit switch for an ATM network by recycling data cells through the switch fabric a multiple number of times with a copy-by-two network creating an additional data cell upon each recycle to thereby satisfy the number of connection addresses in the multicast connection. Resequencing of the data cells may be implemented at the exit to the switch fabric as well as upon each recycle of data cells through the switch fabric.
