Abstract: A locking differential includes a pair of opposed collinearly arranged annular clutch members the adjacent faces of which contain corresponding pairs of V-shaped drive grooves for receiving a cylindrical drive pin that is connected with the differential casing, the planar faces of the drive grooves being arranged at an obtuse angle of about 120°. Preferably, in order to obtain line-to-line contact with the drive pin, each of the four planar drive faces of a clutch member has an angle of convergence of about 3.017° relative to the diametrically arranged lines of juncture of the associated pairs of planar drive faces. The clutch members are normally biased apart by helical springs the end portions of which are received in pockets contained in the opposed faces of the clutch members, respectively.  Access slots are provided in the outer circumferential surfaces of the clutch members for introducing the ends of the spring members, when the spring members are in an axially compressed assembling condition, into the respective pockets. A locking pin carried by each clutch member on the face thereof opposite the other clutch member extends within a corresponding locking groove that is contained in the opposite face of, and communicates with the outer circumferential surface of, the other clutch member.

Title: Novel ammonium octamolybdate composition and method for producing the same
Inventor: KHAN MOHAMED H
IPC: C01G39/00
Filed: 1999-06-08
Granted: 2005-06-07
Abstract: A novel isomer of ammonium octamolybdate ("AOM") and method for producing the same. A new AOM isomer("X-AOM") is described which is characterized by a distinctive Raman spectral profile compared with other AOM isomers including .alpha. and .beta. - AOM. Compared to .alpha.-AOM, X-AOM of the present invention offers improved smoke suppression characteristics and greater stability and uniformity. To produce the novel isomer, ammonium dimolybdate ("ADM") (12) is combined with molybdenum trioxide ("MoO3")(34) and water (14) to yield a mixture. When mixing these materials, optimum results are achieved if at least one of the foregoing molybdenum-containing reagents is added in a gradual, non-instantaneous manner so that the selected reagent is not added to the mixture in a single large mass. This gradual delivery procedure, along with a carefully controlled prolonged heating state (e.g. in excess of 3 hours) contributes to a maximum yield of high purity. The method of the present invention facilitates the generation of X-AOM in an effective and preferential manner on production-scale levels. Thus, the present invention addresses the disadvantages of the prior art by being capable of producing large quantities of high purity AOM.

Filed: 1999-07-30
Granted: 2005-04-05
Abstract: A shoulder brace (10) includes a shoulder joint member (14), and a tension trigger (21) which provides compression or relaxation of the joint member such that a patient's shoulder joint is compressed in an anterior-posterior direction when the patient's arm is moved into a danger zone, in order to prevent anterior dislocation of the shoulder join t. The shoulder joint member (14) is provided with a cushion (80) generally aligned with the humeral head. The shoulder brace includes an alignment strap (16) wrapped around the patient's chest, and pivotally attached to the shoulder joint member so that movement of the patient's arm is not inhibited.

Granted: 2004-05-18
Abstract: A wheelchair suspension system comprises a suspension assembly disposed adjacent to each wheel of the wheelchair, and attached to and interconnecting the axle (13) of the wheels to the wheelchair frame.  Each of the suspension assemblies includes a front bracket (16) and a rear bracket (17), wherein the front bracket (16) is attached to the wheelchair frame and the rear bracket (17) is attached to the axle (13). Top and bottom generally L-shaped arms (35) each are privotally attached to each of the brackets in a diametrically opposed fashion, and an elastomeric spring (19) is disposed between and interconnects the arms. When one or more of the wheels encounters a bump in a travel surface of the wheelchair, the arms move closer together to compress the spring. Conversely, when one or more of the wheels encounters a depression, the arms move farther apart to place tension on the spring. The pivoting parallel arrangement of arms and brackets enables displacement of the axle in a substantially vertical, relatively large distance when one or more of the wheels encounter an irregularity in the wheelchair travel surface, which in turn maintains stability and steering control of the wheelchair by keeping the wheels in contact with the travel surface.

Granted: 2005-03-22
Abstract: A molded resin laminate in which the dimensional accuracy and the strength are excellent at a bent portion and a method for producing the same are provided. One, in which an average diameter of small cells existing in a region on a side of a resin cover to be formed into a surface layer is smaller than an average diameter of large cells existing in a region on a side of a base resin component to be formed into a base layer, is used as a foamed resin component to be formed into an intermediate layer of the molded resin laminate. After the base resin component is molded with a molding machine, the base resin component is held on a male mold of a forming machine different from the molding machine described above. A sheet-shaped laminate, which is obtained by joining the foamed resin component and the resin cover, is arranged between the base resin component and a female mold.      Subsequently, the forming machine is subjected to mold clamping. The sheet-shaped laminate and the base resin component are joined to one another in a cavity, and the gas in the cavity is vacuum-evacuated to thereby form the sheet-shaped laminate.

Abstract: A method and apparatus for determining the position of a wireless communication device using global positioning system (GPS) satellites, base stations synchronized to GPS time and base stations that are unsynchronized with GPS time. The unsynchronized base stations are synchronized with one another. Time of arrival information is adjusted to take into account the fact that wireless communication devices that received GPS time information from a base station receive that information biased by the one-way delay that is encountered by the signal that communicates that information to the wireless communication device. In addition, time difference of arrival information for base stations that are not synchronized to GPS time allows the bias between these base stations GPS time to be eliminated.
