  • Patent number: 5023082
    Abstract: The present invention pertains to biodegradable sustained-release composins capable of achieving the sustained release of a pharmaceutical or other agent. The compositions can be formed into implant devices which may be used to treat a wide variety of diseases and conditions. The implants are especially useful in treating diseases such as periodontal disease which require prolonged drug release.

  • Patent number: 4913906
    Abstract: The invention relates to controlled release pharmaceutical compositions. These contain as active ingredient valproic acid, a salt of valproic acid, an ester of valproic acid, Valpromide, or any other pharmaceutically acceptable derivative of valproic acid which upon administration to humans provides a serum level of valproic acid, in combination with an additive which is selected from physiologically acceptable polymeric substances and from native proteins. The active ingredient is usually in the range of from 10 to 80 weight percent. The novel pharmaceutical compositions are prepared by applying a high pressure to a mixture of the ingredients. They result in a prolonged serum level of the active ingredient.

  • Patent number: 4100719
    Abstract: An elongated central shaft is provided at one end with a hook for supporting thereon a hanger for a garment contained thereon. The other end of the central elongated shaft is connected to a mounting element which mounts the arrangement on an apparatus for bagging garments. The elongated shaft has mounted thereabout a spreader unit which is hinged at its ends thereof so that, as a bag is pulled down from an apparatus for bagging garments, the spreader unit positioned about the central elongated shaft will cause the leading end of the bag to open up and thereby avoid contact with the hook and the central elongated shaft.

  • Patent number: 4027461
    Abstract: An elongated central shaft is provided at one end with a hook for supporting thereon a hanger for a garment. The other end of the central elongated shaft is connected to a mounting element which mounts the arrangement on an apparatus for bagging garments. The elongated shaft has mounted thereabout a compressible spreader unit which is hinged at its ends so that, as a bag is pulled down from an apparatus for bagging garments, the spreader unit positioned about the central elongated shaft will cause the bag to open and avoid contact with the hook and the central elongated shaft.

  • Patent number: 3990625
    Abstract: For a bagging device, there is provided a roll of polyethylene bags which are fed through a braking device and thence past spreading devices and a floating hook support, whereupon are engaged sequentially the hooks of hangers upon which garments or the like are supported. The bags are provided with indicia thereupon which can be detected by a detecting device to actuate the braking device so that the bags may be readily torn off before they seat on the respective garments being packaged.

  • Patent number: 3987603
    Abstract: Bags from a roll of polyethylene bags are fed through a braking device and thence past spreading devices and a floating hook support, whereupon are engaged sequentially the hooks of hangers upon which garments or the like are supported. The bags are provided with indicia which are detected by a detecting device to actuate the braking device so that the bags may be readily torn off before they seat on the respective garments being packaged. Provision is made for adjustments of the braking time so that the brake automatically releases after a fixed period of time thereby facilitating a drawing of the bags from the source for sequential bagging operations.

  • Patent number: 3961460
    Abstract: A bagging device is provided with a floor supported device having a roll of polyethylene bags thereon, which are fed through a braking device and thence a round spreading devices and a floating hook support, whereupon is engaged sequentially the hooks of hangers upon which garments or the like are supported. The bags are provided with indicia thereupon which are detected by a detecting device to actuate the braking device so that the bags may be readily torn off before they seat on the respective garments being packaged. Provision is made for adjustments of the braking time so that the brake automatically releases after a fixed period of time thereby facilitating a drawing of the bags from the source for sequential bagging operations.
