Abstract: Transforming a starchy material comprises heating it at 60 - 100 degrees C for 5 - 30 minutes, in a dry phase with a chemical agent, to bring about hydrolysis. Starchy material is transformed by a continuous process of chemical fluidification in a dry phase, (i.e. less than 25% humidity, preferably 8 - 22% humidity), using a chemical agent having a hydrolyzing action, the temperature being 60 - 100 degrees C and the period of action being 5 - 30 minutes. The starchy material used may be any of the following: raw starch, flours, products resulting from the etherification, esterification, sulfonation, oxidation, cationization, hydroxy alkylation, and/or acetylation of these starches and flours, and their mixtures. The chemical agents used may be mineral or organic acids or (per)oxidizing agents, in liquid, solid, or gaseous form. The use of 0.01 - 0.4% hydrochloric or sulfuric acids, calculated on dry weight of starchy material, is especially preferred. During or after this process the product may be transformed by chemical modification, such as etherification, esterification, sulfonation, cationization, hydroxy alkylation or acetylation. Independent claims are also included for cationic starchy material having a water fluidity of at least 65, preferably 70 - 79, a nitrogen content of 0.3 - 0.5%, preferably 0.3 - 0.48% expressed in relation to the weight of dry cationic starchy material.

Filed: 1998-10-08
Abstract: A wireless data network includes a wireless packet switched data network for end users that divides mobility management into local, micro, macro and global connection handover categories and minimizes handoff updates according to the handover category. The network integrates MAC handoff messages with network handoff messages. The network separately directs registration functions to a registration server and direct routing functions to inter-working function units. The network provides an intermediate XTunnel channel between a wireless hub (also called access hub AH) and an inter-working function unit (IWF unit) in a foreign network, and it provides an IXTunnel channel between an inter-working function unit in a foreign network and an inter-working function unit in a home network. The network enhances the layer two tunneling protocol (L2TP) to support a mobile end system, and it performs network layer registration before the start of a PPP communication session.

Patent CA-2263402-A1 (CA)
Inventor: MOIIN HOSSEIN
IPC: G04G5/00
Filed: 1997-08-07
Abstract: A computing system develops time/date values by using a free-running counter to measure and accumulate increments of time. The increments of time are converted from the resolution of the free-running counter to that used for the time and date values by dividing by a conversion variable and then used to update the time/date value. The accuracy of the time/date value is monitored by periodically comparing the rate of the free-running counter to the rate of a more accurate, external clock. The ratio of these two rates is used to adjust the conversion variable. The conversion variable reflects any differences between (1) the rate of change of the increments of time used for developing the time/data value and (2) the external clock. Its use here, therefore, will operate to either slow down or speed up the rate of change of the time/date value so that it more closely tracks the external clock.

Title: Optical fiber amplifier and optical amplification device for bidirectional optical transmission using the optical fiber amplifier
Inventor: YOKOYAMA JUN
IPC: H04B10/297
Filed: 1999-03-05
Abstract: An optical fiber amplifier comprises a pump light source outputting pump light and an optical amplification medium in which signal light is amplified by pump light. The signal light is input to, and output from, one end of the optical amplification medium. Between the other end of the optical amplification medium and the pump light source is provided an optical filter selectively transmitting the pump light and selectively reflecting light with a wavelength bandwidth equal to that of the signal light. Two optical fiber amplifiers, joined by a 4-terminal fully-circulating optical circulator, are provided to amplify up signal light and down signal light. The up signal light is input into, and amplified down signal light is output from, a first optical I/O terminal. The down signal light is input into, and amplified up signal light is output from, a third optical I/O terminal. A second optical I/O terminal and a fourth optical I/O terminal are connected to one end of the first optical amplification medium and the second optical amplification medium, respectively. The signal light and the amplified signal light are thus input into, and output from, the optical fiber amplifier. A fiber bragg grating may be used as the optical filter. Thus, the optical amplification device for bi-directional light transmission may be reduced in size.
