Title: Articulated vehicle and hinge assembly
Inventor: HUGHES DANIEL L
IPC: F16C19/54
Filed: 1994-03-11
Granted: 2000-06-06
Abstract: A hinge assembly for an articulated vehicle (10) having front and near frame portions (12, 14) joined at a pair of vertically aligned hinges (18, 20). Each hinge includes a similar roller bearing assembly (48) attached to the front frame portion and having a rotatable protruding trunnion (52). The rear frame portion includes recesses (70) for receiving the trunnions and trunnion caps (74) for retaining the trunnions. The trunnion of each bearing assembly includes a shoulder pin (118) with a lust bearing cone (134) plead against the shoulder (126) and a second bearing cone (142) spaced apart from the first cone. A spacer ring (154) received on the pin is biased against the second cone by an end cap (160) secured to the end of the pin. A shim pack (158) between the end cap and the end of the pin limits the amount by which the space between the cones may be narrowed to limit and control the pre-load of the bearing assembly.

Title: Storage, transmission, communication and access to geographical positioning data linked with standard telephony numbering and encoded for use in telecommunications and related services
Inventor: EMERY MARK
IPC: H04M3/487
Filed: 1995-10-11
Granted: 2004-02-10
Abstract: A method and system implementation for combining and accessing telephony numbering and geographical position so direct access to information, services and goods may be invoked through the use of various telephone networks.  The existing telephone networks throughout North America and the world use standardized numbering plans for con-necting to, or switching any subtended device to any other device within the network. The U.S. government has orbited a series of communication satellites which pro-vide a signaling method for determining precise geo-graphical location throughout the world. This system is called the Global Positioning System (GPS) and provides several levels of service. Each GPS satellite continu-ally transmits a navigation location signal which may be received on the ground, sea, or in the air and when com-bined with signals from other GPS satellites used to pinpoint navigational position in two or three dimen-sions. This invention allows for the storage, transmis-sion, communication, and access to geographical position-ing data determined by GPS or any other method by using the North American or other land based public switched, cellular, satellite, radio, or other telephone system and related intelligent networks.

Title: Immunogenic lhrh peptide constructs and synthetic universal immune stimulators for vaccines
Inventor: LADD ANNA EFIM
IPC: A61P15/00
Filed: 1994-04-28
Granted: 2009-06-30
Abstract: This invention relates to immunogenic luteinizing hormone releasing hormone (LHRH) peptides that lead to suppression of LHRH  activity in males or females. When male rats are immunized with these peptides, serum testosterone drops and androgen-dependent organs atrophy significantly. These peptides are useful for inducing infertility and for treating prostatic hyperplasia, androgen-dependent carcinoma, prostatic carcinoma and testicular carcinoma in males. In females, the peptides are useful for treating endometriosis, benign uterine tumors, recurrent functional ovarian cysts and (severe) premenstrual syndrome as well as prevention or treatment of estrogen-dependent breast cancer. The subject peptides contain a helper T cell epitope and have LHRH at the C terminus. The helper T cell epitope aids in stimulating the immune response against LHRH. The peptides, optionally contain an invasin domain which acts as a general immune stimulator. In another aspect this invention relates to immunogenic synthetic peptides having an invasin domain, a helper T cell epitope and a peptide hapten and methods of using these peptides to treat disease or provide protective immunity. The peptide haptens of the invention include LHRH, amylin, gastrin, gastrin releasing peptide, IgE CH4 peptide, Chlamydia MOMP peptides, HIV V3 peptides and Plasmodium berghei.

Abstract: Dendritic polymer conjugates which are composed of at least one dendrimer in association with at least one unit of a carried material, where the carrier material can be a biological response modifier, have been prepared. The conjugate can also have a target director present, and when it is present, then the carried material may be a bioactive agent. Preferred dendritic polymers are dense starr polymers, which have been complexed with biological response modifiers. These conjugates and complexes have particularly advantageous properties due to their unique characteristics.

Abstract: A mower-conditioner platform or header is suspended from the main frame of the mower-conditioner by a pair of transversely spaced lower links and a single upper link or lift arm.  A hydraulic lift cylinder is connected directly to the lift arm.  The lift arm is mounted between the main and platform frames in a manner for permitting the lift arm to undergo a given amount of side-to-side movement about its connection with the main frame in response to relative vertical movement between the opposite ends of the platform as the platform travels over uneven ground contour during cutting operation, and for limiting the side-to-side movement of the upper link to an amount considerably less than said given amount when the platform is raised to its transport position. Three different connection points are provided at the forward end of the lift arm for connection to the platform frame and by selecting different ones of these points different platform cutting angles may be obtained.  A transport lock is provided for holding the lift arm in its raised position and the mounting of the cylinder is such as to permit the latter to be stroked when the lock is engaged without any forces being transferred to the lift arm or lock.

Catalytical ly cracked products and spent cracking catalyst are subsequently removed from the riser reactor, the spent cracking catalyst is regenerated in a catalyst regeneration zone to produce hot regenerated cracking catalyst which is recy cled to contact said heavy fraction and cracked products are recovered.

Title: Method and apparatus for frequency assignment for a communication unit
Inventor: RUPPEL JOHN STEPHEN
IPC: H04W36/00
Filed: 1995-12-21
Granted: 1999-11-16
Abstract: A method for improved frequency assignment includes recording handoff statistics for subscriber units handing into and out of a base station (130). The handoff statistics include the IDs of the other base stations (240) involved in the handoff, along with the date and time of the handoff.     The statistics of the handoff count are applied based on the number of occurrences within a time period (450), and are used to accept or reject the potential frequency assignments obtained from an assignment algorithm. In one embodiment of this algorithm, using a Q estimate, obtained from residual powers recorded on each frequency (435), a candidate frequency is chosen based on the lowest Q value. This candidate is tested against the handoff statistics, and if rejected, a frequency with the next lowest Q level is tested.     This process is repeated until a frequency is assigned.

Abstract: A method of producing an optical waveguide grating by exposure to light.  An optical waveguide having a core composed of a material wherein the refractive index changes due to exposure to UV light is formed into an optical waveguide grating by applying a grating portion formation step wherein a grating portion is formed by irradiation with UV light at a predetermined spacing, and an overall exposure step after formation of the grating portion wherein the entire grating portion is irradiated with UV light.  As a result, the effective refractive index of the grating portion is changed so as to allow the central wavelength to be adjusted without changing the rejection.  Consequently, the grating properties can be precisely and easily controlled.
