Abstract: In winding machines, in which the run-off bobbins are supplied in a verticle position at the winding stations, it is known that, after a change of run-off bobbin, the thread start is located in the unwinding position and, for joining together with the thread end of the run-on bobbin, is inserted into a thread-end joining device or is applied to an empty tube for the winding-on of a run-on bobbin. Since the location of the thread start on the run-off bobbin in the unwinding position is time-consuming and lowers the efficiency of the winding station, it is proposed, according to the invention, that the thread start (51) deposited at a preferred point on the tube tip (52) be sucked up as early as when the run-off bobbin (15) is in the stand-by position (49). The thread is sucked up by means of a suction pipe (38) which is connected to a catching funnel (53) located above the run-off bobbin (15) which is in the stand-by position (49). During the change of the run-off bobbin, the run-off bobbin (15) which is in the stand-by position (49) is transferred in a vertical position to the unwinding position (6) and, at the same time, the sucked-up thread start (73) is supplied to the thread-end joining device (25) and inserted in it or is applied to an empty tube. <IMAGE>

Abstract: A beverage package and a method of packaging a beverage such as beer containing gas in solution has a container can 1 having a primary chamber 1A charged with beer 14 to form a small headspace 15. The can 1 is sealed and includes a submerged insert 8 forming a relief chamber 6 which is sealed by a closure 11. The insert 8 is responsive to heat applied during pasteurisation which causes the closure 11 to open the relief chamber so that the latter can accommodate beer derived from the primary chamber 1A to provide an enlarged headspace 15A. The small headspace 15 initially provided facilitates removal of air therefrom prior to sealing of the container while the enlarged headspace 15A is adequate to accommodate froth or foam developed by the intentional liberation of gas from solution in the beer. An insert part 7 forming a secondary chamber 5 may be provided for injecting gas or liquid into the beer to liberate gas therefrom for froth or foam development in the enlarged headspace. The relief chamber 6 may contain gas under pressure so that when opened to the primary chamber the release of such gas pressurises the enlarged headspace 15A. The insert part 7 may be located within the relief chamber 6.

Abstract: Data samples describing a plurality of micro-segments that compose a symbol to be recognized are received from a device (10) such as an electronic pad. Preprocessors (20, 22, 24) map the micro-segments into cells of a plurality of feature arrays (50, 52, 54) with different resolutions. Preprocessors assign values to the cells based on the length of a micro-segment associated with the cell, and how well the features of the associated micro-segment correspond to the feature label of the cell. The cell values are used as inputs to comparators (30, 32, 34) that compare the feature arrays with reference arrays. The results of comparisons involving lower resolution feature arrays and reference arrays, are used to limit the number of comparisons involving higher resolution feature arrays and reference arrays. The highest resolution comparison selects the reference array that identifies the symbol to be recognized.

IPC: H03H9/64
Filed: 1994-07-20
Abstract: This invention relates to an electronic device having a frequency dependent signal transfer characteristic which is electrically coupled to at least one SAW transducer. The SAW transducer acts as a SAW impedance element since it exhibits frequency dependent electrical characteristics. Such characteristics are utilised so that the transmission loss of the SAW impedance element is high in a relatively low signal transfer region of the signal transfer characteristic of the electronic device, and low in a relatively high signal transfer region of the signal transfer characteristic of the electronic device. This has the advantage that signals outside of the passband of the electronic device can be attenuated without increasing the transmission loss of the electronic device in its passband.

Abstract: An automated optical character recognition method is provided for use in conjunction with a programmable digital processing device. The method inputs a sequence of values representing one or more characters in an array of characters to be optically recognized. The values define one or more dimensional characteristics of the characters. From the input values, a standard dimensional value is determined from a frequency distribution of a selected one of the character dimensional characteristics. For each of the input characters, a set of normalized values is determined from the standard dimensional value. The normalized values correspond to the one or more character dimensional characteristics. Optical character recognition is thereafter performed using the normalized values.

Abstract: A ventilator/dryer assembly for drying wet air comprising a treatment chamber (7), a rotary drying device and a forced circulation mechanism housed in a case main body provided with an air inlet port (3) and an air outlet port (4) exposed to the outside is characterized in that the treatment chamber (7) is divided into a primary side section (7A) and a secondary side section (7B) with the rotary drying device (20) disposed therebetween, that the forced circulation mechanism draws air from the room where the ventilator/dryer assembly is installed via said air inlet port (3) to the primary side section (7A) of the treatment chamber (7), passes it through the rotary drying device (20) and sends it back into the room through the secondary side section (7B) of the treatment chamber (7) and the air outlet port (4) by means of a single blower (10) and that the rotary drying device (20) is adapted to take a drying position (20A), a regenerating position (20B) and a heat recovering position (20C) sequentially in the sense of rotation, the device adsorbing moisture from the air passing therethrough from the primary side section (7A) of the treatment chamber (7) in the drying position (20A), hot air being made to pass through the device in the regenerating position (20B) to remove moisture adsorbed by the device in said drying position, cooled air being made to pass through the heated device in the heat recovering position to cool the device heated in said regenerating position (20B). With such an arrangement, the operation of drying wet air in the room where the assembly is installed by means of the rotary drying device and that of regenerating the rotary drying device can be carried out on a continuous basis in the drying mode of operation. Additionally, since the forced circulation mechanism of the ventilator/dryer assembly comprises a single blower (10) that draws and discharges air both for air circulation in the room and for regeneration of the rotary drying device (20), the overall configuration of the ventilation system of the room can be simplified for downsizing to realize a lightweight apparatus at reduced cost. Finally, the assembly can significantly reduce the contamination of the rotary drying device (20) as compared with a comparable conventional apparatus that use ambient air as regenerating air.

Abstract: Abstractions of digital images are created and displayed by generating, in accordance with an undersampling routine, pixel identifiers which identify pixels for extraction from the digital image, extracting pixels from the digital image in accordance with the pixel identifiers, and displaying the extracted pixels against a predetermined background, the extracted pixels being displayed in substantially the same relative position as in the digital image. The predetermined background is selected so as to enhance viewability of the abstract image, or the predetermined background may be previous displays of image extractions so as to allow a fill-in effect for single digital images or an abstract motion video effect for digital images that comprise frames in a digital motion video sequence. Since only abstractions are retrieved and displayed, overall time for retrieval, transmission and display of the images is significantly shortened.

Abstract: An improved process is provided for forming a highly planar BPSG interlevel dielectric. The process includes using a silane based source material placed within a plasma enhanced CVD chamber. The plasma enhanced CVD chamber undergoes high energy plasma deposition by applying an RF energy exceeding 950 watts in order to minimize formation at silicon-rich intermediates upon the semiconductor substrate. Moreover, densification of the BPSG material occurs within an oxygen ambient to enhance the formation of silicon dioxide having a flow angle substantially less than lower power, non-oxygen densified processes. Still further. BPSG can, if desired, be selectively etched to form a more planarized topography or a possibly recessed topography. Selective etching is brought about by a photolithography mask used to form the underlying conductors.
