Abstract: Abstract of the Disclosure A type setting device for printers, comprising a drive motor, a drive gear mounted on a rotary shaft and rotated by the drive motor, a type wheel having a plurality of type elements and rotatably mounted on the rotary shaft, a first spring clutch interposed between the drive gear and the rotary shaft, a ratchet gear fixedly mounted on the rotary shaft and selectively stopped to control the first spring clutch, and a second spring clutch adapted to prevent the rotary shaft from being rotated reversely with respect to the rotation of the drive gear.  The drive gear can thus be kept rotating at all times so that it is unnecessary that the motor be star-ted and stopped every time a character is printed.  This allows a high-speed type selection and high-speed printing.

Abstract: ABSTRACT         A sealing device comprises a door or gasket of rigid material curved in one direction and straight in another, as in the form of a portion of a cylinder, and having convex and concave surfaces. Either or both such surfaces has a circumferentially continuous groove across the straight and curved portions that contains a molded in-place packing of resilient material.  The packing has a portion projec-ting from the groove and has a recess extending into the groove.  The sides of the recess are parallel to a tranverse access divided by the intersection of the surfaces; the direction of the access corresponds to the direction of travel of the mold members relative to each other when separating so that there is no undercut in the packing material into which portions of the mold would project and prevent separation of the mold members after the molding operation without damaging the packing.

Abstract: Abstract Improved infusion web material for tea bags and the like is provided by using synthetic pulp in the heat seal phase and forming therein an array of a large number of small discrete craters.  These craters, which exhibit an average planar area of at least about 1 x 10 -3 square centimeters, are formed prior to drying the initially formed multi-phase material by directing a low impact mist-like liquid spray onto the  heatseal phase.  The droplets from the spray dis-place the fibers to form the shallow craters and, at times, expose portions of the underlying non-heat seal fiber phase. The small craters are present throughout the heat seal phase at a concentration of at least about 40 per square centimeter and occupy about 10-75 percent of the total exposed surface area of the heat seal fiber phase of the material.  The web also is treated with a surfactant.

Abstract: 48,561 ABSTRACT OF THE DISCLOSURE Protected  liquid-filled  electrical  inductive apparatus having a dry well fuse assembly which includes a dry well fuse holder sealingly disposed through an opening in  the  associated  metallic  casing,  separate  from  the electrical bushings,  and a removable fuse portion.  The dry well  fuse holder  includes  first  and second spaced terminals  each  having portions  immersed  in  the  liquid dielectric and portions accessible within the dry well for cooperative engagement with contacts on the removable fuse portion.   The first terminal is closer to the metallic casing than the second terminal.   Ionization of the air within  the dry well  fuse holder adjacent to the first terminal is prevented by a tubular shield member mounted on the outside of the dry well fuse holder.  One of the axial  end portions of  the  tubular  shield member makes electrical contact with the immersed portion of the first terminal.   After  making  such  electrical  contact,  the inside diameter of the shield member then steps or flares outwardly to a larger inside diameter to provide a prede-termined uniform spacing between the inner wall of the shield member and the outer wall of the dry well fuse holder.   The shield member is dimensioned to extend to-wards the casing, past the end of the portion of the first terminal which is accessible from within the opening in the dry well fuse holder.

Abstract: HEAD PRESSURE CONTROL INCLUDING MEANS FOR SENSING CONDITION OF REFRIGERANT                 ABSTRACT OF THE DISCLOSURE          A sensing device detects "flashing" in a refrigerant liquid line, upstream from the expansion valves of the evaporators of a refrigeration system.  In response, a valve opens in a line extending between the compressor discharge line and a receiver, to bypass discharge vapor into the receiver, thus raising the head pressure to an extent sufficient to satisfy the requirement for a steady liquid refrigerant flow at the expansion valve.  The head pressure is raised only to the minimal extent necessary to satisfy this requirement.  Dis-closed is a sensor of the type incorporating a sight glass in the path of a beam extending between photoelectric cells, though other sensing devices of an equivalent nature can be used.  The invention can comprise a single sensing device in the liquid line extending to one or more evaporators connected in parallel.  Alternatively, one may utilize separate sensing devices, one for each of several evaporators connected in parallel, with each sensing device having the capability of operating the valve, thus to assure a minimal but sufficient head pressure within the liquid line sufficient to maintain a liquid refrigerant seal at the expansion valve where flashing has been detected by its associated sensor.
