  • Publication number: 20030144106
    Abstract: A differential gear assembly including a differential housing. A pair of side gears substantially axially aligned and spaced apart from each other, wherein the side gears are adapted to be supported by the differential housing and to engage axle shafts. A pair of pinion gears substantially axially aligned and spaced apart from each other, wherein the pinion gears are adapted to engage the side gears. A ring gear is mounted externally to the differential housing and a pinion pin engages and extends diametrically across the ring gear. The ring gear includes features adapted to receive the ends of the pinion pin and to position the pinion pin relative to the ring gear such that a center of mass of the ring gear is aligned with a center of mass of the pinion pin.

  • Patent number: 5651853
    Abstract: In order to laminate a fabric to a plastics material grid formed of oriented strands connected by junctions having thicker and non-oriented or less-oriented nodes, the fabric and the grid having the same melting temperature, the grid is heated by a drum to melt the surfaces of the nodes, and the grid and the fabric are passed through a nip formed by nip rollers, the fabric having been pre-heated by passing around a preheat roller. One nip roller has surface protuberances formed by knurling of such a size that a number of protuberances engage (by way of the fabric) each node of the grid.

  • Patent number: 5612081
    Abstract: To apply hot grit particles to a continuous thermoplastic web such as a geonet, the web is brought to the upper part of the surface of a roller which is rotating in a container containing grit particles. A controlled layer of grit particles is carried up over the upper part of the roller, and the particles are heated by halogen emitters and are pressed into the web, causing local melting of the web so that the grit particles are embedded and firmly retained. Grit particles are added to a hopper and the top surface of the mass of grit particles adjacent the ascending part of the roller surface is kept at a controlled level below the uppermost part of the roller. Surplus grit particles not taken up by the web are recirculated by interaction with the roller surface.

  • Patent number: 5273804
    Abstract: To form a paved surface, a laminate is used which has on the bottom a geotextile fabric with the mesh structure on the top. The fabric is adhered to the road base by spraying or spreading a bituminous liquid onto the base and laying on the laminate and applying further adhesive to the top of the laminate; asphalt is then placed and rolled. The laminate is formed of a square or rectangular mesh structure which has oriented stands connected at junctions which are thicker than the strands and have low-orientated or unorientated nodules. On one side the surface of the nodules are melted and the fabric is pressed into the nodules so that the plastics material of the nodules envelopes some of the fibers or filaments of the fabric to form a mechanical bond. In this way, the oriented strands stand proud of the fabric, to enable the asphalt aggregate to penetrate into the meshes and interlock with the strands.

  • Patent number: 4993550
    Abstract: In order to provide a suitable packaging system, mesh pieces are deposited across the width of a moving run of flexible wrapping material and are deposited in longitudinally overlapping relationship along the length of the wrapping material, by feeding the mesh pieces on a belt which moves more quickly than the wrapping material; the mesh pieces are ejected from the end of the belt onto the wrapping material. The direction of movement of the wrapping material is inclined downwards so that the trailing ends of the mesh pieces contact the wrapping material before the leading ends contact the preceding mesh piece. The wrapping material, with the mesh pieces on it, is then rolled up under tension into a spiral bale so that the overlapping edges curl down and prevent the mesh pieces slipping out.

  • Patent number: 4202386
    Abstract: A funnel for use in filling containers with liquid and designed to prevent overflowing of the container during filling. The funnel has two air vents one of which is adapted to be closed during initial filling of the container while the other stays open to vent the container during this inital filling. When the container is nearly full, the liquid in it closes the second vent and this provides an indication in the funnel that filling is nearly completed. The first vent is then opened to allow filling of the container to be completed with a small amount of liquid remaining in, or added to, the funnel.

  • Patent number: 4027460
    Abstract: Apparatus for packaging commodities particularly delicate articles consists of a hollow vertical mandrel over which a tubular flexible packaging material is driven. The material is axially slit as it passes over the mandrel to allow the commodities to be inserted into the mandrel through a product opening and the tube is axially resealed and transversely sealed on issuance from the mandrel discharge end. According to the invention a platform is provided below the mandrel which is lifted into the mandrel interior so that the commodities can be inserted through the product opening and supported by the platform to prevent their dropping through the mandrel interior. The platform is then retracted to provide descending continuous support for the commodities during the remainder of the packaging process.

  • Patent number: 3952127
    Abstract: An extruded integral plastics net structure comprising first sets of spaced parallel strands, second sets of spaced parallel strands extending transversely thereto, the sets of strands being joined together at all or certain of their points of intersection to form a net structure wherein the intersection points along any one strand are in the alternating forms of any two of the following: (a) integral masses of mirror image symmetry about the median plane of the net, (b) assymetrical junctions in which there is substantially only linear contact and adhesion between the strands and (c) symmetrical junctions having only linear contact with little or no adhesion between the strands.
