  • Publication number: 20080105519
    Abstract: A conveyor belt assembled of modular plastic components is retained together without the usual connecting rods or pins. In one embodiment the modules, each of which has series of finger-like projections or knuckles both at forward and rear ends of the module, the projections are tapered to narrows in width from top to bottom. The projections at either the forward or rear side have laterally extending posts or dowels at one side of each projection, each with a length that extends through only part of the width of the gap between adjacent projections. In the opposite set of projections are holes, similar to the aligned holes that are present when module rows are connected by rods. With the projections being tapered, modules of adjacent rows can be put together by interdigiting the projections with the modules of adjacent rows held at an angle, preferably an acute angle beyond 90°.

  • Patent number: 7278536
    Abstract: A conveyor chain for poultry processing is formed of injection molded regular links in serially connected relationship, and has at intervals a special link adapted to receive a threaded stud for a chicken carcass-supporting cone or other structure. The special link has a base portion which is of preferably the same configuration as the regular links. Above this, integrally molded with the base portion, is a platform with laterally outwardly extending flanges for stability against tilting. A threaded boss extends up from the platform and has a threaded internal bore extending vertically, to receive a threaded stud. The threaded boss comprises a relatively light plastic cylinder and has regularly extending buttresses stabilizing it on the platform. The special link is integrally formed by injection molding of a suitable material such as acetal, and is light in weight and profile.

  • Patent number: 7228959
    Abstract: A modular plastic conveyor belt achieves a very tight turning radius. The belt is configured to permit the belt module rows to collapse using an over/under slotted module geometry, allowing for modules of one row to slip over/under modules of an adjacent row at the inside of a curve. This allows greater collapse and thus much tighter turning radii. A belt of two inch pitch can achieve an approximately 0.33 turning ratio, the ratio between turn center distance and width of belt.

  • Patent number: 6969744
    Abstract: Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with an N-substituted pyrrole to thereby functionalize the N-substituted pyrrole at the terminal reactive polymer chain end(s). Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is substituted at the 2 and 3 position of the N-substituted pyrrole.

  • Patent number: 6906011
    Abstract: This invention is directed to a new low molecular weight copolymer (The PIB/UAR copolymer) that may be prepared by reacting a low molecular weight polyisobutene (PIB) having less than about 32 carbon atoms with an unsaturated acidic reagent in the presence of a free radical initiator. No chain transfer agent is required to prepare the low molecular weight PIB/UAR copolymer. The PIB/UAR copolymer may be useful as is, or as an intermediate for (1) polysuccinimides, (2) detergents or dispersants for lube oil or fuels, (3) pour point depressants and (4) surface sizing agents for paper. The PIB/UAR copolymer may be used by itself or as the ester, amide, imide or metal salt derivative of the PIB/UAR copolymer. The PIB/UAR copolymer may be liquid at ambient temperature.

  • Patent number: 6796418
    Abstract: A helical or “spiral” conveyor belt system is retrofitted with further belt supports, added between existing belt supports, when needed for heavier loading, preferably without removing the belt from the spiral support structure. The additional support apparatus includes a series of snap-on plastic brackets, to be snapped over the cantilevered bars that extend horizontally inwardly at intervals to support the belt. These brackets form channels within which a set of metal rail members are held, the rail members being in sections securable together around the helical path. A U-shaped wear strip, preferably continuous, is placed down over the metal rails after assembly. This rail addition can be accomplished without removal of the belt, which can be lifted in place sufficiently to assemble the intermediate support components.
