  • Patent number: 5323711
    Abstract: Railcars for transporting timber in either the "tree-length" form or "long log" form are provided. The present invention includes a railroad car comprising a central support member having at least one set of wheels disposed near its ends. A bulkhead is affixed to each end of the central support member and a plurality of cross members extend from the central support member, to which a plurality of stanchions are affixed. Thus, the cross members and the stanchions preferably form substantially "U"-shaped structures that are in a spaced-apart relationship selected to restrain both tree-length logs and long logs. The railroad car of the present invention may also include one or more apparatus for restraining a stack of timber, such as a winch and a strap. Most preferably, at least six pairs of stanchions are provided. The distance between a first stanchion and the bulkhead is between about 7.5 and 8.5 feet; the distance between the first stanchions and a second stanchion is between about 12.0 and 13.

  • Patent number: 5286845
    Abstract: The present invention relates to the conversion of tall oil soap to produce crude tall oil. An aqueous tall oil soap solution generated in a kraft wood-pulping process is placed in contact with carbon dioxide, under pressure, to form crude tall oil and sodium bicarbonate brine. The crude tall oil and sodium bicarbonate brine are then allowed to separate, under pressure, into a crude tall oil layer and a sodium bicarbonate brine layer. The crude tall oil layer is then separated from the sodium bicarbonate brine layer, again under pressure. The separated crude tall oil may then be further refined to yield fatty acids, resin acids, and other constituents, which are useful in numerous industrial applications, such as in soaps, lubricants, inks, adhesives, and coatings.

  • Patent number: 5283319
    Abstract: The present invention provides for the efficient recycling of carbon dioxide used in high pressure tall oil soap acidulation processes. The excess carbon dioxide used in the high pressure tall oil soap acidulation processes is recycled and contacted with an aqueous tall oil soap solution at a point before the high pressure contacting stage. Preferably, the recycled carbon dioxide is contacted in a first reactor, under pressure, to provide a preliminary tall oil mixture having an extent of acidification beyond the presence of a gel phase. Methods are provided for the monitoring of the acidulation reaction in the first reactor to maintain the extent of acidification beyond the gel phase region.

  • Patent number: 5242545
    Abstract: Paper suitable for use in corrugated shipping containers is provided. Medium paper of this invention has a basis weight of at least about 15 pounds and a relatively high cross-direction crush resistance typically exceeding 2.4 pounds force per six inches width per unit base weight of the oven-dried product in lbs/1000 ft.sup.2. Linerboard of this invention has a correspondingly greater cross-direction crush resistance. The paper is preferably produced by applying starch solutions at high percent solids at elevated temperatures using a size press technique to provide at least about 30% of the starch in a defined inner zone of the paper sheet. The strength of the paper is improved through a carefully controlled distribution of the starch throughout the thickness of the paper.

  • Patent number: 5217208
    Abstract: Methods and apparatus for maintaining a restraining device placed over a load in constant tension as the load shifts during transit are disclosed. The present invention provides a winch having two ratchets, the first of which provides the initial tension in the restraining device. The second ratchet is connected to a spring, which is connected to the shaft upon which the restraining device is wound. By operating the second ratchet, the spring is displaced and an urging force is created. Upon a reduction of the initial tension in the restraining device, the urging force acts upon the shaft, advancing the shaft and the first ratchet, thereby maintaining the tension in the restraining device. Since the first ratchet is advanced, any slack in the restraining device is accumulated and the strap is locked into a tighter position. Methods and apparatus providing a locking bar to prevent unauthorized use of the winch and theft of the restraining device are also disclosed.

  • Patent number: 5186586
    Abstract: A remote release mechanism is disclosed which permits restraints such as flat straps placed around a load and placed in tension by a winch to be released by an operator positioned on the same side of the transportation structure as the winch. Thus, the present invention permits the hook end of a load restraint to be released from the winch side of the transportation structure, thereby eliminating the need to perform separate operations on either side of the restraint mechanism. In a preferred embodiment, the present invention provides apparatus comprising a hook bar connected to a rotatable drum which is held from rotation in one direction by a ratchet and pawl. Upon release by the application of force to a remote release rod, the hook bar is released and permitted to rotate, thereby causing the hook which connects the restraint to the hook bar to fall away, releasing the restraint. Methods of remotely releasing a load restraint are also disclosed.
