Title: Method for making submicrometer carbides, submicrometer solid solution carbides, and the material resulting therefrom
Inventor: DUNMEAD STEPHEN D
IPC: C01B32/949
Filed: 1994-05-26
Abstract: A method for making submicrometer metallic carbides and submicrometer solid solution metallic carbides from a source of at least one metallic oxide and carbon involves the rapid heating of a reactive particulate mixture of the source(s) and carbon in order to achieve a resulting particulate size of less than 1 micrometer.   The rapid heating may produce either a finished product or a precursor. If a precursor is produced, it may be admixed with additional carbon and subjected to a second rapid heating step to prepare a finished product. Submicrometer sized metallic carbides and solid solution metallic carbides were suitable for use in commercial ceramic applications.  The smaller sized particles produce a product having superior toughness and hardness.

Patent CA-2175941-A1 (CA)
Inventor: ESSENWANGER KENNETH A
IPC: H03M1/78
Filed: 1996-05-07
Abstract: A DAC converts a sequence of digital codewords into an approximately piecewise linear analog waveform that follows rising and falling edges between plateau levels.  The DAC processes, in parallel, each bit of the codewords to pro-duce component waveforms that are weighted according to their bits significance and summed together to produce the piecewise linear analog waveform.   Waveform shaping cir-cuits control the rise and fall times of each component waveform so that the analog waveform's rising and falling edges settle to within a desired error bound of a linear output ramp whose slope is a function of the difference between successive codewords and the rise or fall times. The rise and fall times are preferably approximately the same.  Limiting switches control the plateau levels of the component waveforms so that the analog waveform's plateaus settle to within the desired error bound of the ideal val-ues represented by the codewords.  The linear region of the limiting switches are expanded to maintain the linearity of the rising and falling edges established by the waveform shaping circuits.

IPC: B65H31/36
Filed: 1995-03-03
Abstract: A first shaft 21 and a second shaft 31 parallel with each other are provided near an inlet 14 of a bill storage chamber 10. Taking-in runners 20 are disposed on the first shaft 21 and taking-in rollers 30 are disposed on the second shaft 31. The taking-in runners 20 and the taking-in rollers 30 differ in position in a direction in which the shafts extend. Further, the sum of the radius of each taking-in runner 20 and that of each taking-in roller 30 is larger than the spacing between the first shaft 21 and the second shaft 31. Thus, if a plurality of overlapped bills are caught in the space between the taking-in runners 20 and the taking-in rollers 30, they are bent in a wavy form and the intimate contact force between the bill is lowered significantly, causing the bills to be easily aligned.

Patent CA-2188596-A1 (CA)
Inventor: ESKINS KENNETH
IPC: A23L27/00
Filed: 1995-04-21
Abstract: A stable and non-separable composition comprised of starch and oil can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the oil into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions that are nongreasy, yet slippery to the touch. These compositions are useful as thickening agents, suspending agents, fat substitutes, and seed coatings. They are receptive to the addition of a variety of water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, agricultural chemicals, and the like.

Abstract: Procédé et appareil de détection d'anomalies tissulaires notamment de tissus précancéreux du col de l'utérus par spectroscopie à fluorescence ou Raman, ou leur combinaison. Des mesures effectuées in vivo par fluorescence ont été suivies de mesures in vitro par spectroscopie Raman dans le proche I.R. sur des biopsies du col humain. Les spectres de fluorescence recueillis pour des excitations à 337, 380 et 460 nm ont servi à mettre au point une méthode de diagnostic permettant de différencier les tissus normaux d'avec les tissus atteints de dysplasie qui donne une sensibilité de 80 % et une spécificité de 67 % pour la différenciation des lésions intraépithéliales squameuses (SIL) d'avec les autres tissus. Selon un autre aspect de l'invention, on a pu, par l'observation des pics de diffusion Raman à des longueurs d'onde données, distinguer des lésions intraépithéliales squameuses avec une sensibilité de 88 % et une spécificité de 100 %. On peut de plus distinguer correctement les échantillons d'inflammations ou de métaplasies d'avec les SIL.
