Title: Dryer sections provided with intermediate calendering in a paper machine
Inventor: KUHASALO ANTTI
IPC: D21F5/04
Filed: 1997-02-11
Abstract: The invention concerns a dryer section of a paper machine which is provided with one or several nips (NK;NKP) of intermediate calendering and in which dryer section there are several successive wire groups (R). The dryer section is primarily or exclusively composed of groups (R1...RV) with single-wire draw, in which the heated drying cylinders (20, 20a) are placed in the upper row and the reversing suction cylinders (30, 30a) or reversing suction rolls (30aa) are placed in the lower row. The groups (R1...RV) with single-wire draw comprise a drying wire (21) which runs along a meandering path over said drying cylinders (20, 20a) and reversing suction cylinders or rolls so that the reversing suction cylinders (30, 30a, 30aa) remain inside the loop of the drying wire (21). Inside the group (Rn) with single-wire draw or in connection with the last drying cylinder (20a), a free space has been arranged, in which a calender roll (10; 10P) is fitted, which forms a calendering nip (NK;NKP) together with the last-mentioned drying cylinder (20a), through which nip the paper web (W) to be dried is passed and, thus, calendered inside the dryer section. Further, five other embodiments of the invention are described.

Filed: 1996-05-06
Abstract: A process for the recovery of propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is cooled and/or expanded to partially condense it, then separated to provide a first vapor stream. The first vapor stream is directed into a contacting device whereby a third vapor stream and a C3-containing liquid stream are formed. The C3-containing liquid stream is directed to a distillation column wherein a second vapor stream is separated to recover a product containing the major portion of the C3 components and heavier hydrocarbon components. The second vapor stream is directed into heat exchange relation with the third vapor stream to cool the second vapor stream and condense at least a part of it, forming a condensed stream. At least a portion of the condensed stream is directed to the contacting device to intimately contact the first vapor stream; the remaining portion of the condensed stream is supplied to the distillation column as its top feed. The quantities and temperatures of the feeds to the contacting device and the distillation column are effective to maintain the overhead temperatures of the contacting device and the distillation column at temperatures whereby the major portion of the desired components is recovered.

Patent CA-2263424-A1 (CA)
Inventor: DONALD BRUCE RANDALL
IPC: G06T13/00
Filed: 1997-07-28
Abstract: A constraint-based graphics system employs different examples of an image to define the constraints of the system. The examples are grouped into subsets which can be interpolated with one another, according to a user-specified input that determines the relative proportion of each example image. An animation can be created by defining a sequence of such interpolated images.  Alternatively, a user can directly manipulate observable components of an image to define a particular state for the image. Automatic transformations are defined to provide registration of an image within an overall scene by shifting the frame of reference for an image so that unnatural movements do not occur as the animation proceeds through a sequence of states. The structure of the system permits an animation to be divided into distinct components that can be combined with complementary components of other animations, to provide new results. These components include a clip motion which defines a sequence of states, a clip character which applies the clip motion to a particular image configuration, and clip art.

Patent CA-2264443-A1 (CA)
Title: Switching power supply
Inventor: HATAKEYAMA HARUHIKO
IPC: H02M3/335
Filed: 1999-03-05
Abstract: A switching power supply has first and second switching elements that are alternately turned on to cause an alternating current to flow through a primary winding of a transformer. The alternating current flowing through the primary winding induces voltages respectively across first and second secondary windings of the transformer. Synchronous rectifying transistors are turned on by the voltages induced across the first and second secondary windings, causing a current to flow alternately through the first and second secondary windings. Either one of the first and second switching elements is turned on while the other is being turned off, except for short off-times in which both the first and second switching elements are prevented from being turned on. As a result, when currents flow through the first and second secondary windings, the synchronous rectifying transistors are turned on. Therefore, no current flows through internal parasitic diodes of the synchronous rectifying transistors, and hence any loss caused thereby is very small.

Abstract: A subscriber line tester that allows high-speed, long-time measurement is realized. The subscriber line tester is for communication lines that convey high-speed digital data. A transmission side tester has a signal generator connected to one end of a communication line and a first controller to control the signal generator. The first controller divides a measuring frequency region into two or more blocks, generates multi-sine waveforms obtained by combining sine waveforms of two or more frequencies in each block, and outputs the multi-sine waveforms to the communication line. A reception side tester has an A/D converter connected to the other end of the communication line, a memory, and a second controller to control the A/D converter and the memory. The second controller measures the mufti-sine waveforms in the most suitable measuring range for each block, and synthesizes a spectrum from each spectrum obtained for each of the above blocks.
