Patent CA-2234268-C (CA)
Inventor: ONO TAKUJI
IPC: F26B21/14

Abstract: Disclosed is a method of sterilizing and dewatering food in a shortened length of time, still permitting the processed food to remain an elongated length of time in good taste.        The inner pressure of the insulated dryer is raised by feeding nitrogen gas after evacuating the insulating dryer, and at the same time, pieces of food are exposed to the spray of ethanol, so that the oxygen gas remaining in the tissue of food may be replaced by nitrogen gas to prevent oxidization of food, and at the same time, ethanol penetrates the food well for sterilization. Next, the inner pressure of the insulating dryer is reduced by removing nitrogen gas therefrom, and the pieces of food are exposed to the far-infrared radiation to be heated, thus preventing evaporation of water from the pieces of food to prevent their temperature from being lowered, and expediting removal of water in the surrounding low-pressure atmosphere to provide semi-dried products.        The sterilization-and-water removal has the effect of extending the preservation period of dried food. Also advantageously, the dewatering of food at a low temperature has the effect of substantially preventing the discoloring and deteriorating of the dried food, permitting the long-lasting of good taste.

Title: Apparatus and method for demodulating a modulated signal
Inventor: BROWN TYLER A
IPC: H04B1/707
Filed: 1997-08-13
Granted: 2001-03-27
Abstract: A receiver includes both a coherent and noncoherent demodulator (222). When the confidence that estimates of the channel is high, the coherent demodulator (408, 409, 425, 412) is implemented (400, 418). When the confidence that estimates of the channel is low, the noncoherent demodulator (422, 421) is implemented. A controlling microprocessor controls the selection process and also provides a signal to enable the noncoherent demodulator in instances when noncoherent demodulation would most likely be better than coherent demodulation. As an example, such an instance would be immediately after handoff of a mobile station from a source base-station to a target base-station.

Abstract: A transfer capable of applying one- or multi-coloured patterns to textiles under heat and pressure comprises a carrier sheet (1) having a non-binding surface which carries (a) a one- or multi-coloured pattern (5) printed on the carrier sheet using a digitally controlled colour printer; (b) a transparent (6) or white-pigmented (7) elastomer layer of a polymer having a high plasticizing point printed configuratively on the pattern (5); and (c) a heat-activatable thermoplastic polymeric glue layer (8) printed configuratively on the transparent (6) or white-pigmented (7) elastomer layer or a heat-activatable hot melt granulate sprinkled on the elastomer layer while said layer was still wet. An even better encapsulation of the coloured pattern is obtained when the carri er sheet has printed thereon a first transparent elastomer layer of a polymer having a high plasticizing point, and the pattern is printed on this elastomer layer using a digitally controlled colour printer. Additional strength is obtained when both a transparent elastomer layer and a white-pigmented elastomer layer are printed on top of the coloured pattern.

Abstract: A voltage detector (12) detects the voltage levels of the battery blocks of the battery set (10). A presence of an overdischarged cell is detected when a voltage difference between each of the battery blocks reaches or exceeds a predetermined value (for example, 1V). At this point, a battery  ECU (14) sets the SOC value of the battery set (10) at the lower control limit value (for example, 20%). This triggers an HV  ECU (16) to control the load (18) such that charging is effectuated in the battery set (10). If further discharge occurs, the battery set (10) is disconnected from the load (18) by a relay (20).

Abstract: This invention relates to a process for the production of polyurea encapsulated fertilizer particles. These are produced by applying an isocyanate-reactive component which contains at least two amine groups to fertilizer particles to form amine coated particles, and applying a polyisocyanate component to the amine coated particles to form polyurea coated particles. Theses steps may optionally be repeated in successive order. The resultant polyurea encapsulated fertilizer particles contain from about 0.5 to 15 % by weight of polyurea, based on the total weight of the encapsulated fertilizer particles. Instead of using an amine group containing isocyanate-reactive component, water can be applied first.

Title: Method and radio station for transmitting data
Inventor: BAHRENBURG STEFAN
IPC: H04J13/00
Filed: 1998-07-20
Granted: 2004-09-28
Abstract: According to the invention, in a method for data transmission in a radio communications system, a radio interface is subdivided into time slots for transmission of bursts. In this case, the data are transmitted in data channels in a time slot, in which case the data channels can be distinguished by means of an individual spread code. A finite burst comprising data symbols and at least one interblock sequence with known symbols is used for data transmission in a data channel. At least one parameter is determined for the traffic conditions of the radio interface, and the ratio of the length of the interblock sequence and a data part with data symbols is adjusted depending on the traffic conditions. The method is suitable in particular for use in 3rd generation TD/CDMA mobile radio networks.
