Abstract: The present invention facilitates temperature control of a rotating mandrel during deposition of a substance on the mandrel, an example being deposition of synthetic diamond on a rotating mandrel using a plasma for chemical vapor deposition of the diamond.  A deposition chamber is provide for containing heated constituents of the substance.  A mandrel assembly is provided, and includes a mandrel mounted on a base.  The mandrel assembly is rotatable on an axis, and the mandrel thereof has a surface in said chamber.  The mandrel base has a first fin that extends outwardly from the rotation axis of the mandrel assembly.  A translatable assembly, having a second fin that can overlap said first fin, is provided, the translatable assembly being translatable to change the extend of overlap of the first and second fins.  Means are also provided for rotating the rotatable mandrel assembly, and means are provided for translating the translatable assembly.  Heat exchange means are coupled with said translatable assembly.  Means are provided for controlling the translation of the translatable assembly to control the thermal coupling between the mandrel assembly and the heat exchange means. In the method of the invention, a technique is disclosed for depositing a substance, comprising the steps of: producing a vapor containing constituents of the substance; providing a rotating mandrel assembly that includes a mandrel which is exposed to the vapor and a base having a plurality of radiator fins extending therefrom; interleaving a plurality of receptor fins with the radiator fins; and providing heat exchange to the receptor fins to cool the mandrel during deposition of the substance on the mandrel.  Moving the receptor fins controls the extent of interleave thereof with the radiator fins, so as to control temperature of the mandrel.  In a disclosed embodiment, the temperature in the region of the mandrel is measured, and the moving of the receptor fins is in accordance with the measured temperature.

Title: Complex cepstrum analyzer for speech signals
Inventor: MITOME YUKIO
IPC: G01R23/16
Filed: 1995-02-14
Granted: 1999-03-16
Abstract: Respective samples of input speech data are transformed by a discrete Fourier transformer to obtain a spectrum of the speech data.  Simultaneously, values of times of the respective samples are multiplied with the input speech data by a multiplier and a differential spectrum is obtained by transforming a result of the multiplication by a discrete Fourier transformer.          A real part of a value obtained by dividing the differential spectrum by the spectrum by a quotient real part calculator and the real part is inverse-transformed by a discrete inverse Fourier transformer.          The result of the inverse-transformation is divided by the values of the times of the respective samples to obtain a time function corresponding to phase.          On the other hand, a time function corresponding to a logarithmic amplitude spectrum is obtained from an output of the inverse-Fourier transformer by means of a logarithmic amplitude spectrum calculator.  A complex cepstrum is obtained by adding the both time functions at respective times by an adder.

Title: Intelligent call waiting
Inventor: EISDORFER JERRY
IPC: H04M3/42
Filed: 1995-04-27
Granted: 1999-01-19
Abstract: Methods and apparatus are disclosed for using information about a calling party's identity or the importance of a call to control the call waiting signal played to a called party that is busy on another call. Upon determining that a called communication station is busy on another call, information about the identity of the calling party is obtained from the calling station. This information is processed to determine call routing treatment, and particularly to determine whether a call waiting signal is to be played for the call and, if so, what type of call waiting signaling is to be played. The called party can determine information about the identity of the calling party from the call waiting signaling, and thus determine whether to interrupt the call in progress to respond to the call waiting signal. In one exemplary embodiment of the invention, information about the calling party's identity is used to provide a distinctive call waiting signal which identifies the caller as being a particular individual or as a member of a particular group of individuals. In another exemplary embodiment of the invention, information about the calling party's identity controls whether a call waiting signal is played to the called party or suppressed.

Abstract: Method and kits are provided for detecting one or more target nucleic acids. A first oligonucleotide having a 3' amino group and a second oligonucleotide having a 5' phosphate group are annealed to a contiguous complementary region of a target nucleic acid. Whenever the 3' terminal nucleotides of the first oligonucleotide and the 5' nucleotides of the second oligonucleotide are complementary to the opposing nucleotides on the target nucleic acid, a nucleic acid ligase ligates the first and second oligonucleotides via the formation of a phosphoramidate linkage. The presence of the target nucleic acid is determined by detection of the ligated first and second oligonucleotides.

Abstract: The subject disclosure relates to the identification of mutations in the I i protein which result in an alteration of the endoprotease cleavage pattern of the mutant I i as compared with the endoprotease cleavage pattern of the wild type product. Methods for the identification of such mutants, and the mutants themselves are useful for the identification of classes of compounds to be further tested for immunomodulatory activity. A specific example of such a use is the screening of small organic compounds for the ability to bind to an intermediate in the I i endoprotease processing pathway. A small organic molecule having the ability to bind to such an intermediate can be further screened for the ability to modulate antigen presentation.

Abstract: Digester systems for producing paper pulp from comminuted cellulosic fibrous material take into account the level of dissolved organic materials (DOM), such as lignin, hemi-cellulose, and cellulose, maintaining the DOM level at about 100 g/l throughout the cook (particularly kraft cook). In order to make sure there is sufficient liquid to slurry the material in the feed system of a two vessel system, some liquid is withdrawn from the circulation conduits between the digester and impregnation vessel, cooled, and fed to the feed system. In a vapor phase digester, the level of liquid at the top of the digester is more precisely controlled by circulating some of the withdrawn liquid from a circulatory loop of the digester to the level tank associated with the feed system. An in-line drainer may be provided in the feed system between a make-up liquor pump and a liquid inlet conduit leading to the top of an impregnation vessel. Within the digester, a set of extraction/dilution screens is provided specifically positioned and spaced from each other, and with respect to a reintrodcution conduit opening, so that mixing of different DOM concentration liquids is minimized.
