Abstract: Abstract of the Disclosure The invention is a method for adding sub-stantially insoluble material to an at least partially liquid metal.  The method comprises providing a com-bination of a first metal having discrete degenerate dendrites and a plurality of insoluble particles at least partially suspended in the first metal.  The combination is mixed with a second metal at a tempera-ture above the solidus temperature of the first metal and the second metal.  The second metal is capable of forming a dendritic structure when cooled from a liquid state to a solid state.  The mixture is then solidified into a dendritic-containing metallic structure having a plurality of substantially insoluble particles at least partially suspended in the structure.

Abstract: ABSTRACT A method for detecting and quantitating: any organism containing ribosomal RNA; any member of a large organism category, such as the group of all bacteria; any member of a small organism category such as members of a taxonomic species of bacteria; any member of an intermediate sized organism category; and previously unknown organisms. The method comprises contacting the nucleic acid of the organism whose presence, identification, and quantitation are to be determined, with a marked probe comprising nucleic acid molecules complementary to R-RNA sequences of the said organism, under nucleic acid hybridization conditions, and then determining the degree of hybridization that has occurred. Illustratively, Mollicutes and other bacterial organisms which may be present in a cell-containing medium are detected identified and quantitated by contacting a probe which consists of marked single strand nucleic acid molecules which are complementary to the R-RNA of a member of the class Mollicutes, under hybridizing conditons, with nucleic acid isolated from the cells in the said medium, whereby the probe hybridizes only with R-RNA from any member of the Mollicutes or other bacterial organisms present in the said medium, and then determing the number of Mollicutes organisms present in the medium. Also, illustratively, Trypanosoma organisms (a type of protozoan) which may be present in a mammalian cell containing medium are detected by contacting a probe which consists of a selected marked single strand nucleic acid which is complementary to the R-RNA of a member of the taxonomic group Trypanosoma under hybridization conditions, with nucleic acid isolated from the cells in the said medium, whereby the probe hybridizes only with R-RNA from Trypanosoma present in the said medium, and then determining the number of Trypanosoma organisms present in the medium.

Abstract: ABSTRACT            An apparatus and method  for signal processing employing intraframe  and  interframe  variable  prediction  transform coding.   Images are represented by  sequential  frames of two-dimensional  arrays  of digital  signals.   The  digital signals are transformed to form transform coefficients for each frame.   Predicted  transform coefficients are formed using sets of variable prediction factors.  The predicted transform coefficients  for each frame are compared with corresponding actual transform coefficients for the frame to  form  transform  coefficient  difference  signals.   The difference signals are processed to control their range of values.  The processed difference signals are statistically coded such that the more frequently occurring values are represented by shorter code lengths and the less frequently occurring values are represented by longer code lengths.          The coded signals are stored in a buffer memory for trans-mission.

Abstract: ABSTRACT     There is provided both method and apparatus for trans-mitting and receiving an analog signal which involves encod-ing and decoding the signal.   The transmission process in-volves the steps of: a)  converting a basic analog signal into a parallel digital signal; b)  applying to the parallel digital signal a prede-termined code; c)  converting the coded digital signal into a coded analog  signal having  a band-width  substantially identical with that of the basic analog signal; and d)  transmitting the signal thus coded in analog mode.      The receiving process involves subjecting this coded analog signal successively to stages which are the inverse of stages c), b) and a), the inverse coding algorithm being the homologue of the coding algorithm corresponding to the prede-termined code.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides methods and apparatus for improved error detection in a data processing system.  The techniques of the present invention insure that there is a high probability that an error in a record of data (each record comprising a plurality of data bits) is detected.  In the event of an error, the present invention applies a randomizing function to the error which modifies subsequent bits within the record and then propagates and further randomizes the error throughout the record to magnify its apparent size.  The randomizing and propa-gation of the error significantly lowers the misdetection pro-bability for random errors within a record, in that error detect-ability is no longer pattern sensitive.  The use of both propa-gation and randomization functions significantly alters the data containing an error, such that a high probability of detection using check-sum techniques exists.
