Abstract: A screen reeling device includes a frame, an axle, a driving member, an elongated roller, and a biasing member. The frame includes left and right bracket members. The axle has a proximate end mounted to the right bracket member, and a distal end. The driving member is retained slidably and rotatably on the frame and has a right transverse end wall proximate to the right bracket member, and a left end portion. The elongated roller is adapted to be wound with the screen thereon, and includes a left end portion journalled on the left bracket member and an axially hollowed right end portion which is sleeved securely on the left end portion of the driving member to be rotatable therewith. The biasing member biases the right transverse end wall axially toward the right bracket member.
Abstract: An on-machine-seamable multi-axial press fabric for the press section of a paper machine is made from a base fabric layer assembled by spirally winding a fabric strip in a plurality of contiguous turns, each of which abuts against and is attached to those adjacent thereto. The resulting endless base fabric layer is flattened to produce first and second fabric plies joined to one another at folds at their widthwise edges. Crosswise yarns are removed from each turn of the fabric strip at the folds at the widthwise edges to produce seaming loops. The first and second fabric plies are laminated to one another by needling staple fiber batt material therethrough. The press fabric is joined into endless form during installation on a paper machine by directing a pintle through the passage formed by the interdigitation of the seaming loops at the two widthwise edges.
Abstract: A device for feeding and discharging a work in an automatic hollow-pipe cutting apparatus comprises: a cutter device for cutting a hollow pipe; a cam lever driving mechanism for sending the hollow pipe to the cutter device; a fixed chuck device disposed near the cutter device; a movable chuck device disposed away from the cutter device; a movable die core disposed inside the cutter device and inside the hollow pipe; another cam lever driving mechanism for moving the movable chuck device; a stopper and ejector fitted to the fixed die core; whereby when the hollow pipe is fed to the cutter device, the fixed chuck device grasps and release the hollow pipe and the movable chuck device also grasps and release the hollow pipe but at timing different from grasping and releasing by the fixed chuck means and the feeding of the hollow pipe into the cutter device is performed by movement of the movable chuck device by means of the other cam lever driving mechanism, and after the hollow pipe is cut, during lowering of a
Abstract: In a food-like medicine comprising a seamless capsule enclosing effective ingredients and at least one of a gel and a high viscous liquid, the seamless capsule has: a diameter (d) within a range of 0.5-5 mm, a relation of a membrane thickness (.theta.) of the seamless capsule to the diameter (d) being 0.01 d.ltoreq..theta..ltoreq.0.05 d, and a ratio (.rho.) of a major axis to a minor axis of the seamless capsule not more than 1.3.
Abstract: Disclosed is an image forming apparatus for forming an image on roll paper. The image forming apparatus is provided with a printing head to form an image in accordance with an image data, a sheet feed mechanism to feed the roll paper, and a cutter which cuts out the printed portion of the roll paper. The image forming apparatus is further provided with an information recording system which records information related to the roll paper on downstream side of the portion at which the cutter cuts the roll paper.
Abstract: A thermal transfer printing mechanism for use in a facsimile device includes a separating guide surface that is formed having a curve having a radius of curvature of not more than 1.2 mm. Consequently, the acceleration in a separating direction of an ink film separated from an image receiving sheet by the separating guide surface is increased, and the ink film is smoothly separated from the image receiving sheet. The separating guide surface may be formed as a bent thin plate, an embossed portion, a deformed edge of a supporting member, a plastic attachment, or a plastic tape. The separating guide surface is formed as a curve continuing from a feeding guide surface, and the feeding guide surface bends the sheet and the ink ribbon from a plane connecting a contact line of a thermal head and the ink ribbon and a contact line of the sheet and a sheet guide member provided downstream of the separating guide surface.
Abstract: A sonic toothbrush and method produces acoustic pressure. A predetermined bristle tip velocity is generated under applied load. A predetermined acoustic pressure is produced under applied load. A predetermined shear stress is produced and predetermined mechanical power is produced. Bacterial and microbial plaque under the gumline and in pockets is dislodged without physical contact between the plaque surface and bristle tips.
Abstract: A device for feeding ammunition in the form of a continuous belt into a weapon carried on an aircraft; the device having a rigid conduit extending longitudinally along a side of the fuselage of the aircraft, and in turn having a rear portion for loading the ammunition, and a front portion connectable to the weapon by a flexible conduit; the rear portion of the rigid conduit being of such a width as to house the ammunition in two rows, in an accordion configuration; and the front portion being narrower to house the ammunition in a single row.
Abstract: A papermaking apparatus such as a Fourdrinier table which includes a long blade and a trail blade. In the first aspect of the invention, the long blade includes an upper undulated surface with vents passing from the upper undulated surface to the lower surface of the long blade which is at substantially atmospheric pressure. In the second aspect of the invention, the trail blade includes an elevator-type device for adjusting the vertical position of the trail blade. In a third aspect of the invention, a single elevator is used to adjust the angle of the blade, the blade is provided as a modular or multiple-piece design, mounting buttons are used to engage slots of T-shaped cross section in the blade and/or ceramic inserts are included at wear points.

Abstract: A peel seal zipper tape for reclosable plastic bags or packages includes a first and a second mutually interlocking zipper profile disposed on a top surface of a laminated film strip. The top surface is formed by a layer of a sealant material. The laminated film strip also has a middle layer, or core, of a material stiffer than the first and second mutually interlocking zipper profiles, and may also have a bottom layer of a sealant material. In use, the laminated film strip is folded over, and the zipper profiles are interlocked with one another. In doing so, portions of the top surface of the laminated film strip face inwardly, so that the folded film strip may be closed with a heat seal. The outside of the folded peel seal zipper tape, that is, the bottom layer of sealant material is bonded to plastic sheet material from which reclosable plastic bags or packages are made. In the production of the bags or packages, the mutually facing portions of the laminated film strip are sealed together.

Abstract: In a sheet sorting device for distributing sheets consecutively fed from an image forming device such as a copying machine to sorting trays aligned in multiple stages at high speed, there are disposed sheet pressure members for pressing down preceding sheet or sheets previously introduced into the designated sorting tray so as to successfully introduce the following sheet into the designated sorting tray without being hindered by the preceding sheet or sheets on the designated sorting tray. Since the following sheet is in no way hindered by the preceding sheet on the sorting tray in entering into the designated tray by means of the sheet pressure members, the interval between the adjoining sorting trays can be reduced thus to diminish the sorting device in size.
Abstract: A shaker head for a harvester of plant produce comprises jaws 1, 2 pivotally connected together at 3 and having resilient clamp pads 6 adjacent the free ends thereof. A shaking mechanism is housed in a space in one or both jaws behind clamp pad 6. Jaws 1, 2 are operable by ram 4, 5 to grip part of a plant and, on actuation of the shaking mechanism, to shake it to jar produce therefrom. Each clamp pad 6 is provided with a plurality of bores, each bore extending from a mouth in the gripping surface of pad 6 for more than half the thickness of the pad.
