  • Patent number: 5171671
    Abstract: A novel retinoic acid receptor is disclosed. The novel receptor is encoded for by cDNA carried on plasmid phRAR1, which has been deposited with the American Type Culture Collection for patent purposes. Chimeric receptor proteins are also disclosed. The chimera are constructed by exchanging functional domains between the glucocorticoid, the mineralocorticoid, the estrogen-related, the thyroid and the retinoic acid receptors. In addition, a novel method for identifying functional ligands for receptor proteins is disclosed. The method, which takes advantage of the modular structure of the hormone receptors and the idea that the functional domains may be interchangeable, replaces the DNA-binding domain of a putative novel receptor with the DNA-binding domain of a known receptor such as the glucocorticoid receptor. The resulting chimeric construction, when expressed in cells, produces a hybrid receptor whose activation of a ligand-(e.g.

  • Patent number: 5160544
    Abstract: An improved hot filament chemical vapor deposition (HFCVD) reactor is disclosed comprising a gas dispersion system, a filament network and an apertured support plate for the substrate. The apertures in the support plate provide for counteracting the natural pressure and temperature gradients which arise within the reactor so that a uniform deposit or material can be coated over the entire surface of multiple small pieces simultaneously. Specifically, the apertured support plate substantially reduces the extent of radial (stagnation point) gas flow adjacent to the substrate which significantly improves coating uniformity.

  • Patent number: 5161157
    Abstract: A field-programmable redundancy apparatus for integrated circuit semiconductor memory arrays is disclosed. The present invention allows the user to replace a defective memory cell with a redundant memory cell while the integrated circuit memory array is in the field. The user communicates with the redundancy apparatus over standard signal paths of the integrated circuit semiconductor memory array and with standard voltage levels. The redundancy apparatus detects a predetermined code sequence on one or more of the address and data lines of the memory array to enter a special redundancy-reconfiguration mode. In the reconfiguration mode, the redundancy apparatus provides information on the availability and functionality of the redundant memory cells and enables the user to replace a defective memory cell with a selected redundant memory cell.

  • Patent number: 5154332
    Abstract: A multifunctional enclosure for back-carried equipment. When used with equipment that provides a harness for carrying the equipment on a user's back, this enclosure provides a number of features relating to the transportation, storage and usage of the equipment. When used as an enclosure for a backpack, the backpack is inserted into the enclosure and the contents are transported by means of a handle or shoulder strap in a manner similar to a duffel bag. Whenever the backpack must be left unattended for any period of time, a padlock can be used to interconnect the zippers to prevent the zippers from being unzipped. For additional security, a metal cable can be used to secure the invention and enclosed backpack to an an immobile object. This feature allows the traveler to leave the backpack unattended for short periods of time without the fear of theft of the contents or the backpack itself.

  • Patent number: 5149550
    Abstract: The present invention provides methods for making pet chews. According to the invention, ligaments from cattle and other hoofstocks are rendered substantially free of fat and then dried until the de-fatted ligaments are hardened and suitable for use as pet chews. According to the invention, the ligaments are rendered substantially free of fat in one of two ways: (1) either by washing the ligaments in an aqueous degreasing solution comprised of water, strong alkali (e.g., sodium or potassium hydroxide) and cleaning agents or (2) by roasting the ligaments until they are rendered substantially free of adherent fat. With the aqueous degreasing method, the washed ligaments are roasted until they assume a pleasing color. Following roasting, the ligaments may be further dried until they are hard and "bone like", and suitable for pets to chew on.

  • Patent number: 5124943
    Abstract: An improved computer network which utilizes the communication lines of a telephone system to provide connections between computing equipment in geographically mode area is described. The network utilizes a plurality of network units which are coupled by communication links within a telephone system. Each of the network units transmits user data and commands directed to other network units. Each of the network units monitors transmission errors within the telephone system. The data transmission rate within the network can be automatically varied in response to the observed error rate in a manner which reduces transmission errors within the network. When the transmission errors subside, the transmission rate is automatically increased to provide greater data throughput. The network includes features that allow it to be topologically altered without the need to send telephone technicians to the various locations serviced thereby.
