Title: Measurement of melting points of multiple samples
Inventor: BRADLEY MARK
IPC: G01N25/02
Filed: 2004-10-11
Abstract: In a method of measuring a temperature value associated with melting, softening or decomposition of sample substances, an array of samples is deposited onto a support tray. -fhe support tray is placed onto a heating device provided with temperature sensing means, the support tray is illuminated, and the array of samples is observed by a imaging device. WNle varying the temperature of the heating device, the image data from the imaging device is fed to an image recording device and temperature values associated with each feed of image data are also recorded. The image data is reviewed to detect changes in the image, such as image intensity, at each or selected sample locations, and thetemperature of the heating device at an image change associated with a change in state of a sample is logged. Image processing software may be used to detect changes in the image, for example in the intensity of the image, at each sample location. The method may be used as a means for rapidly obtaining a melting point value for comparison of the physical characteristics of the members of a library of samples, especially polymer samples.

Title: Method of producing salts of dinitramidic acid
Inventor: VOERDE CARIN
IPC: C01B32/60
Filed: 2005-01-21
Abstract: A method of preparing salt of dinitramidic acid, comprising nitration of an initial compound with a nitrating acid mixture to form dinitramidic acid in a reaction mixture. A positive ion is added to the reaction mixture and forms with the dinitramide ion an ion pair complex which precipitates in the acidic reaction mixture, and the precipitate is separated from the mixture. The remaining spent acid can be reprocessed for recovery of acid for preparation of a new nitrating acid mixture. The preferred positive ion is the guanylurea ion which gives a precipitate of guanylurea dinitramide. The precipitate can be used as starting material for preparation of other dinitramide salts, such as KDN and ADN. The guanylurea ion can be formed in situ in the process by cyanoguanidine being reacted with the reaction mixture.

Inventor: CHAMPAGNE MICHEL
IPC: A01K5/02
Filed: 2006-09-01
Abstract: An automated pet feeding machine has a very simple system for measuring and distributing food quantities using the combination of an electric motor that moves a rod linearly and slidable panels to control the flow of food pellets into a bowl. The downward tilt motion of the food tray blocks any food from flowing out of the hopper during this step. A  reverse rotation of the electric motor returns the food tray to its first position where the hopper's exit is liberated and a portion is once again poured into the food tray, ready for the next feed cycle.

Title: Minimization of transient noises in a voice signal
Inventor: HETHERINGTON PHILLIP A
IPC: H04R3/00
Filed: 2006-10-06
Abstract: A voice enhancement system is provided for improving the perceptual quality of a processed voice signal. The system improves the perceptual quality of a received voice signal by removing unwanted noise from a voice signal recorded by a microphone or from some other source. Specifically, the system removes sounds that occur within the environment of the signal source but which are unrelated to speech. The system is especially well adapted for removing transient road noises from speech signals recorded in moving vehicles. Transient road noises include common temporal and spectral characteristics that can be modeled. A transient road noise detector employs such models to detect the presence of transient road noises in a voice signal. If transient road noises are found to be present, a transient road noise attenuator is provided to remove them from the signal.
