  • Patent number: 8927495
    Abstract: Adrenocortical disease (ACD) in ferrets develops as a result of the effect of increased concentration of Luteinizing Hormone (LH) on adrenal LH receptors. This increase in LH often results from the neutering of male or female ferrets. Neutered ferrets have no negative feedback of the ovarian or testicular hormone and as a result LH is elevated 3 to 10 times normal. Elevated LH may be prevented and/or treated by injection of GnRH vaccine. Administration of GnRH produces antibodies to endogenous GnRH. The GnRH-anti-GnRH immune-complex is ineffective in stimulating the release of LH and FSH in the anterior pituitary resulting drop in concentration of LH in the systemic circulation. This reduction in LH significantly reduces the occurrence or clinical symptoms of ACD therein. Moreover, treatment of ferrets with the GnRH provides long term relief from ACD for a period of a year or more.

  • Patent number: 5375034
    Abstract: A silicon capacitive pressure sensor is disclosed having a silicon diaphragm and a silicon substrate arranged in parallel and separated by a glass dielectric spacer. The glass is deposited onto a surface of the substrate using an ion milling machine. The sensor further includes a transition piece attached to a second layer of glass insulator disposed between the silicon diaphragm and the transition piece. The transition piece has a throughbore formed therein for applying a fluid to a surface of the silicon diaphragm, the fluid having a pressure desired to be measured by the sensor. The glass disposed between the diaphragm and the transition piece is deposited onto the transition piece using the ion milling process.

  • Patent number: 4621339
    Abstract: A single instruction, multiple data stream parallel computer using bit-serial arithmetic whereby the machine's basic operation is performing Boolean operations on huge vectors of 0's and 1's. The machine utilizes an architectural approach whereby the memory of a conventional machine having 2.sup.k words each t bits long, is reorganized into p registers each 2.sup.k bits in length and adding processor logic to each bit position of the registers and a communication network being added which allows for the 2.sup.k pieces of processing logic to interact. This machine is capable of executing a wide variety of algorithms at a speed of 2.sup.k /p to 2.sup.k /p.sup.2 faster than conventional machines. The machine provides for an ability to handle a variety of algorithms by interconnecting the individual processor elements in a general interconnection network capable of performing a permutation of n bits held one in every processor element in a time of (O(log(n)).

  • Patent number: 4519559
    Abstract: Each landing gear of the undercarriage of an aircraft includes an hydraulic cylinder, and the hydraulic cylinders are interconnected through hydraulic restoring devices. The hydraulic restoring devices yieldably urge the pistons in each of the hydraulic cylinders to an equilibrium position, thereby restoring the length of each landing gear to an equilibrium length following a disturbance. In non-level landings, the hydraulically interconnected system causes the landing gear that strikes the ground first to be compressed and the other landing gears to be extended; this absorbs some of the energy of the impact. Extension of the other landing gears tends to limit the extent to which landing energy is converted to angular velocity of the aircraft caused by pivoting of the center of gravity of the aircraft about the first landing gear to contact the ground.

  • Patent number: 4488773
    Abstract: An array of optical fibers is precisely positioned in channels in a head when liquid metal, such as tin-lead solder, is used. This is compared to irregular locating which is obtained with organic resins. A glass fiber is first ion plated with about 1.times.10.sup.-6 m of a metal such as nickel which is wetted by the solder. The fiber is placed loosely in a channel in a metal holder and solder is infiltrated. In an embodiment, strain on the glass fiber where it exits its holder channel is alleviated when the polymer jacket is also ion plated with metal and soldered to the holder.

  • Patent number: 4422055
    Abstract: A strain isolation technique for a surface acoustic wave (SAW) device having a piezoelectric SAW substrate is disclosed. A cut in the surface of the piezoelectric SAW substrate forms an isolated surface region where active SAW signal propagation occurs. The cut prevents undesirable surface strains from affecting SAW signal propagation in the isolated region.

  • Patent number: 4216401
    Abstract: An improved SAW pressure sensor structure includes a dual substrate sensor having a SAW substrate with a SAW delay line disposed in an active signal region on a first one of two parallel major surfaces thereof, and having a centrally apertured base substrate of the same material bonded at a mating surface thereof to the second one of the SAW substrate major surfaces with a glass seal, the dual substrates being bonded in crystallographic orientation, the central aperture having segmented portions to provide a major diameter opening at the mating surface coextensive with the active signal region to form a diaphragm and having a minor diameter opening at a second surface of the base substrate at a value less than one half that of the major diameter, the base substrate further including an O-ring groove adapted to receive one end of a cylindrical metal sleeve in a vacuum sealing relationship, the metal sleeve having a diameter equal to one half that of the aperture major diameter, the sleeve being bonded at anoth
