  • Publication number: 20180146807
    Abstract: A form fitting travel pillow having a unique shape that provides positional stability in relation to the wearer's shoulders, and further allows for comfortable use of headphones, is disclosed. The travel pillow is formed with upper and lower concave sections such that the lower concave section fits over and conforms to the wearer's shoulders, while the upper concave section is formed such that the wearer can comfortably wear headphones. In one preferred embodiment, the travel pillow may also include a front snap or latching element to assist in maintaining a proper position of the pillow. The travel pillow may be manufactured from memory foam, and may also include a removable cover that can be readily washed or cleaned. In one embodiment, the travel pillow may also include an attached pocket or bag into which the travel pillow may be easily stowed.

  • Publication number: 20070068987
    Abstract: A utility bag carrier used, for example, in hunting includes a belt that extends around a person's waist, and shoulder straps connected to the rear of the belt. Pouches for storing items are positioned on the left and right sides of the person for convenient access to the items.

  • Patent number: 4698302
    Abstract: A process is provided for the preparation of magnetic particles to which a wide variety of molecules may be coupled. The magnetic particles can be dispersed in aqueous media without rapid settling and conveniently reclaimed from media with a magnetic field. Preferred particles do not become magnetic after application of a magnetic field and can be redispersed and reused. The magnetic particles are useful in biological systems involving separations.
