  • Patent number: 5316394
    Abstract: The radial roller bearing has an outer ring (1), an inner ring (2), several roller members (3), and a cage (4). The cage (4) is guided on the edges (1a) of the outer ring (1) via several supporting rollers (5) distributed around the circumference in the form, for example, of ball bearings. This makes it possible to avoid sliding friction for guiding the cage (4) and to guide the cage without any clearance, so that the roller bearing can attain a high limit speed.

  • Patent number: 5309151
    Abstract: A current supplying integrated circuit which has multi-output for controlling current supply from a current source to a plurality of elements to be driven, such as LEDs, and comprises a plurality of switching devices for controllably supplying the current from the source to the corresponding elements to be driven wherein each of the switching devices has N unit switching elements arranged to be connected in parallel to each other to form a current synthesizing circuit. The unit switching elements have substantially the same current capacity. Each of the elements to be driven, such as LEDs, is supplied with a current whose intensity can be varied by N degrees by the synthesizing circuit. By varying the current intensity supplied to each of the elements, the unevenness in properties among them can be avoided or suppressed in an effective and simplified manner.

  • Patent number: 5298031
    Abstract: The present invention relates to an improved method for embossing and decorating a thermoplastic velvet-like fabric. A transfer sheet supporting a thermally-activated decoration is simultaneously passed with a fabric between two rolls which are under pressure with respect to each other. At least one of the rolls is engraved so as to cause embossing of the fabric. The passing of the fabric and transfer sheet between the rolls is carried out at a temperature sufficient to activate the decoration and allow the transfer of the decoration to the embossed portions of the fabric. The fabric may be heated prior to the embossing-decorating step so that the velvet-like pile is at least partially plasticized. The fabric is then brushed to erect the pile to an erect position. If the decorating is printing, the fabric may be heated immediately before and after the embossing/printing step to transfer a sufficient amount of dye, and to penetrate and seal the dye within the fabric.

  • Patent number: 5290165
    Abstract: An independent pallet delivery system for transporting pallets through a block forming machine that forms concrete blocks on a pallet. The systems includes a pallet magazine for storing a plurality of pallets therein. A conveyor belt formed with a pulley system for transporting the pallets. A pallet pick-up position which receives a pallet from the pallet magazine and places the pallet in a holding position above the conveyor. A jacking assembly is provided to raise that conveyor to engage with the pallet and deliver the pallet to the block forming machine. The block forming machine lifts the empty pallet and forms a molded block thereon. As the block forming machine lowers the pallet towards the conveyor, the jacking assembly lowers the conveyor to cushion the return of the pallet having the molded cement blocks thereon.

  • Patent number: 5289956
    Abstract: A garment hanger adapted to support an elongated rod. The garment hanger includes an elongated body having two ends and a supporting portion therebetween. The ends of the body extend downwardly to form a pair of spaced legs each having a rod receiving portion. Each rod receiving portion is defined by a bottom wall, a back wall joined to the bottom wall and forming a part of the body, a side wall and a front wall joined to the bottom wall and side wall and spaced a predetermined distance from the back wall to define an initial rod receiving pocket. A secondary rod receiving pocket is defined below the initial rod receiving pocket and is offset therefrom. The width of the initial and secondary rod receiving pockets are essentially the same as the diameter of the rod to permit the rod to be locked in the secondary rod receiving pocket.

  • Patent number: 5290109
    Abstract: An electronic typewriter for printing a document having a fixed format with portions thereof containing replaceable character code. The document is stored in an external storage device and read out until a replaceable character code is detected. The replaceable character code is acted upon by replacement with substitute character code or deletion thereof based on instructions communicated to a keyboard. Following input of the instructions, the document is once again read out from the external storage device until the next replaceable character code is detected and acted upon. The sequential reading of the document, detection of and acting upon the detected replaceable character code and automatic reading of the remaining portion of the document until detection of the next replaceable character code, continues until the entire document is read out of the external storage device.

  • Patent number: 5282846
    Abstract: A ravel-resistant, self-supporting woven synthetic fabric vascular graft including a fusible fiber integrated into the weave in the filling yarn is provided. The graft is woven from multifilament polyester warp yarns which can be textured or flat. The filling yarn includes a low melting fusible fiber or resin which can be combined with a stiff monofilament. The monofilament component provides radial rigidity to improve kink and crush resistance. After heat setting, the low melting fusible resin fuses to orthogonal warp yarns at each intersection and provides ravel resistance to the finished graft. Improved kink resistance make the tubular grafts suitable for use in medium and small diameter peripheral applications. A preferred graft has a single velour outer surface and a smooth inner surface.
