Title: Dot scheduling for liquid ink printers.
Inventor: KANG HENRY R
IPC: G06K15/10
Filed: 1997-05-09
Abstract: A method and apparatus of printing with a liquid ink printhead ejecting ink in swaths on a recording medium to form and image including a plurality of dots deposited at pixel locations of a scanline.

Title: Seal for a universal joint trunnion.
Inventor: REYNOLDS JAMES T
IPC: F16C33/78
Filed: 1997-06-09
Abstract: An elastomeric seal assembly for use with a bearing cup mounted on a trunnion of a universal joint cross member includes an elastomeric seal attached to a metallic support ring. The metallic rings are pressed into the open ends of the bearing cups and are retained therein by friction. The elastomeric seals each include first, second and third radially inwardly extending sealing lips. When the bearing cups and sealing assemblies are mounted about the trunnions the annular lubricant sealing lip engages the frustoconical-sealing surface of the trunnion. The annular lubricant sealing lip is slanted towards the closed end of the cup to prevent lubricant from flowing past the seal and out of the roller bearing region. The second sealing lip engages the cylindrical sealing surface of the trunnion and is slanted towards the open end of the cup to resist the entry of abrasive contaminants into the roller bearing region. A third sealing lip engages the cylindrical sealing surface of the trunnion and is slanted in the same direction as the first contaminant sealing lip. The second contaminant sealing lip resists the movement of contaminants towards the first contaminant sealing lip thereby prolonging the life of the seal and universal joint.

Title: Systems and methods for on-line finishing of cellular blood products like platelets harvested for therapeutic purposes.
Inventor: BISCHOF DANIEL F
IPC: A61K35/14
Filed: 1997-02-10
Abstract: Blood processing systems and methods establish on-line communication between a container and a source of blood containing leukocytes and platelets, such as a human donor. The systems and methods create a centrifugal field (14) between the source of blood and the container that separates from the blood an unfinished suspension of platelets having a first physiologic characteristic different than the desired physiologic characteristic. The systems and methods pump the unfinished platelet suspension outside the centrifugal field through a finishing device (24). The finishing device (24) changes the first physiologic characteristic to the desired physiological characteristic, thereby creating the finished platelet suspension. The system and methods convey the finished platelet suspension from the finishing device directly into the container. The systems and methods function without interrupting the on-line communication between the container and the source of blood.

Title: Speech separation method based on time-frequency cross-domain feature selection
Inventor: YILAN LV
IPC: G10L25/30
Filed: 2021-11-17
Abstract: The present invention discloses a speech separation method based on time-frequency cross-domain feature selection, belonging to the field of mono speech separation. The method includes: encoding a single-channel speech by using a one-dimensional convolutional neural network and short-time Fourier transform respectively; fusing feature maps obtained by encoding in two ways; calculating a mask for each speaker by using a separation network according to a feature map obtained by fusion; applying the obtained mask to the fused feature map to obtain a separated feature map of each speaker; and obtaining a speech of each speaker based on the separated feature map of each speaker. Feature selection in speech separation is subjected to cross-domain mixing; features in a time domain and a frequency domain complement each other; and a feature signal of a speech can also be accurately captured in a multi-speaker noise environment; so that the problem of insufficient utilization of features in a time domain and a time-frequency domain in the industry and the existing problem of poor separation in an unstable noise environment are solved.

Title: Continuous prodn. of poly:methyl methacrylate! sheet - using a polymerisation chamber of endless belts sepd. by continuous seals
IPC: B29C48/07
Filed: 1978-11-16
Abstract: The process comprises polymerising methylmethacrylate (opt. together with a copolymerisable monomer) or a prepolymer of this in a space defined by two opposing endless belts, held at a predetermined distance apart by endless seals at the edges, which move together with the endless belts. The monomer is first introduced into the space and polymerised by contacting the outside of the endless belts and seals with hot water. The water is then removed, first from the surface of the belts, then from the outside of the belts between the seals. Polymerisation is the completed at 120-160 degrees C and the finished sheet is removed from the space. Successive removal of surplus water from the endless belts and seals prevents water being drawn into the polymerisation space due to the suction effect creasted in the space as the sheet parts from the belt in later stages of the polymerisation. This improves the appearance of the sheets and overcomes marking of the sheets.
Patent NL-7900121-A (NL)
Title: Heat sensitive pen recorder - with image formed on heat sensitive sheet
IPC: G01D15/34
Filed: 1979-01-08
Abstract: A continuous heat sensitive paper sheet is advanced longitudinally by e.g. a driven roller and a heated pen is pref. moved transversely across the sheet by a driven wire. The drive speeds of the pen and the paper are compared to give a signal which is dependent on the relative speed between the pen and the paper. The signal is used to control the energy supplied to the pen. Impulse generators provide pulsed signals whose frequency depends on the speeds of the pen and paper and a mono-stable multivibrator produces pulsed energy outputs dependent on the mean of the outputs frequency. The pen may be of silicone having P or N type phosphorous or boron dispersions forming a heatable conductive tip or a ceramic having a conductive coating on its tip. The paper sheet may have additive layers so that it can change colour in the region of the image. a fixed visible image is produced immediately. No replenishing with ink or subsequent fixing etc. is required as with conventional machines.

Abstract: The receiver comprises a pair of signal paths arranged in parallel between an RF-input (5) and a superposition circuit (8) and includes, arranged in succession, a pair of first mixing stages (1, 1 min ) the signals from an RF-tuning oscillator (To), being applied in a phase quadrature relationship to these first mixing stages a pair of filtering elements (3, 3 min ) for signal selection and a pair of second mixing stages (2, 2 min ), the signals from a fixed LF-oscillator (Fo), being applied also in a phase-quadrature relationsip to these second mixing stages. The superposition circuit comprising an adding stage (8) arranged between outputs of the two signal paths and producing a first output signal (1). An amplitude and phase balance between the two signal paths is established by an amplitude and phase control of the signals in the two signal paths in dependence on the amplitude and phase of the image interference in the output signal of the superposition circuit. 
<??>The amplitude of this image interference component is measured by detecting the image interference component phase-synchronously, the reference frequency being the detection carrier, and the phase of this image interference component is measured by detecting the image interference component synchronously by means of a detection carrier whose phase is shifted through 90 DEG  relative to the reference frequency. The of necessity equal frequency position between the reference frequency and its image interference component is obtained by means of frequency mirror-inversion.
