Patent CA-2029770-A1 (CA)
Title: Pseudoplastic yellow mustard gum
Inventor: SHARAFABADI SOHEIL K
IPC: A23L27/18
Filed: 1990-11-13
Abstract: An improved process of gum extraction from whole yellow mustard seed is described. The process is time temperature interdependent. In a first step the seed is treated in water, preferably at elevated temperature, the extract is then separated, preferably mechanically, more preferably by a perforated centrifuge, or even more preferably by a slitted centrifuge. The aqueous extract on precipitation and drying gives a gum with pseudoplastic properties similar to those of xanthan gum. The extraction using mechanical separation, especially by a perforated bowl centrifuge, which can be slitted, is suitable for industrial scale extraction of the yellow mustard seed. A centrifuge adapted for juice extraction is suitable. The gum produced under these conditions exhibits unique properties dramatically different from those reported from other previous processes, in both composition and viscosities.

Patent CA-2048762-A1 (CA)
Inventor: CARFI RALPH W
IPC: H03B19/18
Filed: 1991-08-08
Abstract: A low phase noise frequency multiplier is disclosed for multiplying a sine wave obtained from a low phase noise crystal oscillator to higher frequencies than can be directly obtained from a crystal oscillator. The multiplication occurs without the ordinary increase in phase noise. The multiplier, when tripling the frequency contains a low phase noise frequency doubler. The double and triple frequency terms in the tripler are synthesized from two orthogonally related derivatives of the same wave, which are then multiplied in a double balanced mixer.      The process reinforces the desired harmonics while not reinforcing the short term random phase noise, and produces a substantial improvement in the single sideband phase noise ratio over conventional frequency multipliers.

IPC: C21D1/607
Filed: 1991-08-08
Abstract: According to this method, the metal is solidified in a continuous-casting ingot mould consisting of two cooled rolls (2) rotating in opposite directions and arranged opposite each other so as to define a casting space between them, a solidified steel strip (3) is extracted continuously from the ingot mould, and, under the ingot mould, the said strip is subjected to a quenching medium (6) in order to cool it sufficiently rapidly in order to prevent the formation of austenite. This medium may consist of a quenching bath, placed in a container (4) arranged under the rolls (2), and whose bottom is pierced with an opening (5) for the passage of the solidified strip (3). It may also consist of an inert gas in the liquid state sprayed onto the product by nozzles. The steel strips obtained are easier to trim and to coil on exit from the casting line, by virtue of the absence of martensite in the ferritic matrix.
