Abstract: A process for removing volatile constituents from a polymer dispersion or solution by stripping with a carrier gas is disclosed. The carrier gas being, in the case of a polymer solution, the vapor of the solvent used for the polymer solution as an inert gas saturated with said vapor. In the case of a polymer dispersion, the vapor of the dispersing medium used for the polymer dispersion or an inert gas saturated with said vapor. In both processes certain amount of the carrier gas is passed through the polymer dispersion or solution, the volatile constituents taken up the carrier gas on passage through the polymer dispersion or solution are then removed from the carrier gas in such a manner that the energy content of the carrier gas remains essentially unchanged. The carrier gas thus obtained is then reused for further removal of volatile constituents from the same polymer dispersion or solution by stripping.

Abstract: To control a solvent composition in a supercritical fluid system, a first pump pumps a first solvent through a first conduit into a mixer and a second pump pumps a second solvent through a second conduit into the mixer. First and second transducers measure the pressure in the first and second conduits and generate first and second signals proportional to the pressures. Each pressure signal is multiplied by a corresponding programmed concentration signal and compared to the programmed pressure in a feedback system to generate an error signal. The error signal is multiplied by concentration signals from a programmer to control the pumping rate of each pump. The pumps pressurize each fluid one at a time at the start of a run. The pressurization process is also used for producing disturbance-free flow as delivery is changed from one pump to another during prolonged runs.

Abstract: A vibration damping support mechanism (40) for a recorded data reproducing apparatus (10) allows the apparatus to be installed in either a horizontal or vertical position without shifting the tensioning direction of damper springs. In one embodiment (Fig.9) a pair of damping springs is mounted between a main reproducing unit (10) and an outer casing (20). The damper springs (31a,31b) are arranged to extend in the width or depth direction of the main reproducing unit (10) or tilted at an angle. In the horizontal position, external vibrations are absorbed by the elastic action of one (31a) of the two damper springs and in the vertical position, such external vibrations are absorbed by the elastic action of the other (31b) damper spring. 
     In another construction (Fig.2), a damper spring (11a,11b) is mounted between a side panel of the main reproducing unit (10) and a projection (43a,43b) of a spring loaded arm (41a,41b) rotatably mounted on the outer casing (20). The spring loaded arm (41a,41b) is rotated 90 degrees when actuated by a shift lever (38,47a;48a) to set the damper spring (11a,11b) to the horizontal or vertical orientation of the main reproducing unit (10).

Abstract: In the case of known fingerprint pickup devices, the start of the image exposure is realised by means of complicated software solutions. Also, deception by means of published fingerprint photographs is not prevented. In the fingerprint pickup device presented, the start of the exposure is realised by means of monitoring the finger contact pressure. Deception by means of photographs is prevented by means of an alteration in the optical system. An actual identification is carried out via the detection of the dislocation of unique subjective features. The fingerprint pickup device (2) is arranged movably and is held in the quiescent position by an elastic element (10). The pressure sensor (11) coupled to the elastic element (10) generates the exposure start signal. Deception by means of photographs is prevented by means of a more marked tilting of the prism (7). The fingerprint pickup device is used in high security regions, in order to permit only authorised persons access to rooms and the use of special devices.

Abstract: A magnetoresistive read sensor incorporates a granular multilayer sensing element comprising a plurality of layers of generally flat particles (31) of a ferromagnetic material embedded in a nonmagnetic electrically conductive material. A bias layer (45) separated from the magnetoresistive sensing element by a spacer layer (43) provides a magnetic field to bias the magnetoresistive sensing element at a desired non-signal point. The ferromagnetic and the nonmagnetic materials are mutually immiscible, or may be miscible or partially miscible and processed in a manner to control interdiffusion. The magnetoresistive sensing element is formed by alternatively depositing layers of ferromagnetic material and layers of nonmagnetic conductive material on a substrate and then annealing the structure. During the annealing cycle, the layers of nonmagnetic material above and below the ferromagnetic layers penetrate at grain boundaries and break the continuity of the ferromagnetic layers to form layers or planes of ferromagnetic particles embedded in a matrix of nonmagnetic material.

Abstract: The present invention relates to a recording and reproducing method and apparatus for an optical disk (1) of the phase transition type that can be overwritten. According to this invention, the capacity of repeated rewriting of the optical disk (1) is expanded by recording either non-inverted write data (11a) or inverted write data (11b) at random. The deterioration due to the repeated rewriting at a start point and an end point of the recording is suppressed by recording a synchronizing signal before the write data and/or dummy data after the write data in the way such that thermal stress is less likely to occur. A record end position can be determined precisely by detecting a stop pulse to stop recording.

Abstract: A phase-change ink transfer printing process and apparatus (10) applies a thin layer of a liquid forming an intermediate transfer surface (12) to a heated receiving surface, such as a drum (14). Then an ink-jet printhead (11) deposits a molten ink image (26) onto the heated drum where it cools to the drum temperature and solidifies. After the image is deposited, a print medium (21) is heated by a preheater (27) to a predetermined temperature and fed into a nip (22) formed between the heated drum and an elastomeric transfer roller (23) that is biased toward the drum to form a nip pressure that is about twice the yield strength of the ink image. As the drum turns, the heated print medium is pulled through the nip to transfer and fuse the ink image to the print medium. When in the nip, heat from the drum and print medium combine to heat the ink in accordance with a process window (90), making the ink sufficiently soft and tacky to adhere to the print medium but not to the drum. When the print medium leaves the nip, stripper fingers (24) peel it from the drum and direct it into a media exit path.

Abstract: In a DC-DC converter comprising a piezoelectric transformer (25) having an input capacitance between a pair of transformer input teminals and a transformer resonant frequeney, an input switching stage (27) responsive to a DC input signal for supplying a sinusoidal transformer input signal, and an output rectifier stage (29) for producing a converter output voltage across a load resistor (23), the switching stage includes an input series inductor (39) connected in series to one of the transformer input terminals and having an input series inductance that defines a switching resonant frequency in cooperation with the input capacitance to be different from the transformer resonant frequency. It is preferred when the switching stage is operable in zero volt switching that the input series inductance be either between 1.0 and 2.2 µH or between 3.0 and 3.4 µH, or more preferably either between 1.4 and 1.8 µH or about 3.0 µH, if the input series inductance should be 2.8 µH for rendering the switching resonant frequency equal to the transformer resonant frequency. The converter output voltage is controlled by a control stage (51) for feeding the converter output voltage back to the switching stage to reduce an on-off switching frequency of the DC input signal with an increase in load.
