    摘要： An improved catalytic process for selectively ortho-alkylating a phenolic compound which comprises reacting a phenolic compound with an alcohol, optionally in the presence of water, and a catalyst composite consisting essentially of the calcination residue obtained from heating an admixture of magnesium carbonate and/or magnesium hydroxide and a manganese compound.

    摘要： A mechanical system that assembles or deploys pre-stressed structures. The assembly or deployment process outputs and elastically deforms material to form flexural members having a sinusoidal shape and stored potential energy. The sinusoidal shaped members are oriented and deployed with support members as they take shape. Sinusoidal shaped members are formed from a series of contiguous flexures; each flexure's properties may be engineered using a simulation technique. Each flexure is formed from a region of a sinusoidal member's length that begins and ends at antinodes. During assembly or deployment support members are positioned at antinodes maintaining the flexures' shapes and the assembly's pre-stressed state. By controlling the forces applied to and position of each flexure formed during assembly, the distribution of potential energy within the assembly and its secondary shape can be engineered. Elastic potential energy may be harvested from the material forming the flexural members.

    摘要： In accordance with the present invention, a preferred method is disclosed for operating a transfer case synchronized range shift mechanism. The range shift mechanism can be selectively actuated for establishing a four-wheel high-range drive mode, a neutral mode, and a four-wheel low-range drive mode. The synchronized range shift mechanism is comprised of a first input gear system, a second input gear system, and an output gear system. The output gear system is comprised of a rotary output member that may be selectively engaged with either the first input gear system or the second input gear system, depending on which four-wheel-drive operating mode the vehicle operator selects. The range shift mechanism is further comprised of a synchronizing mechanism. The present invention discloses a novel method for controlling the speed of the range shift as a means for reducing the time it takes to perform the range shift.

    摘要： The resiliently coated metallic finger seal described herein is formed of two metallic seal members being fixed together at one end with fingers projecting rearwardly therefrom. The fingers on each member are offset so that the slits of each metallic seal member are not aligned. The fingers of the two members are then encapsulated by a resilient coating material, such as a room temperature vulcanizing silicone rubber. The seal means is described as annular and can be constructed of one piece or a plurality of sections. In constructing the seal means the metallic seal members are cleaned, primed where it is desired to have the resilient coat permanently affixed, and the resilient coat is then applied. The resilient coat does not cover the entire fingers so that the proper flexibility at the hinge location will reamin. After curing of the resilient coating material a heat reflecting and lubricating material is placed thereon.
