摘要： This invention provides improvements in certain processes for alkylating amino acids whereby yields based on amino acid are improved. More specifically, the invention provides a process for the preparation of amino acid derivatives in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group, which comprises reacting, in an aqueous medium at a pH in the range 7-14, a compound of the formula X-A-Y where X and Y are halo atoms which may be the same or different and A is a hydrocarbyl or substituted hydrocarbyl group, in which X and Y are attached to aliphatic or cycloaliphatic carbon atoms, with an amino acid (or salt thereof), wherein the reaction is carried out in the presence of dissolved cations of an alkaline earth metal or of a transition metal and/or wherein the unreacted amino acid is recovered and recycled.

摘要： A method and system for detecting granular data store changes in a computing environment. Data values stored in a first relational database are changed. Each data value is stored in a row and a column of the first relational database. Rows (i.e., changed rows) including the changed data values are identified. Changed rows are propagated to a second relational database. Columns including the changed data values are identified in the second relational database. The types of changes associated with the changed data values are identified. Filters optionally filter out one or more of the changed data values from further processing. At least one data value of the changed data values, along with their types of changes, are transformed into a language neutral format included in packaged data to be sent in response to a client requesting the at least one data value.

摘要： A color liquid crystal display using reflective color filters using layers of cholesteric liquid crystals is disclosed. The reflective color filters have two different center wavelengths and bandwidths per layer and are stacked in two layers to provide colored light for displays. With various numbers of layers in the stack, different polarization levels are provided. The pixels in the display of the invention are arranged such that multiple adjacent sub-pixels in a layer with the same color makes the color filters easier to manufacture.

摘要： Reflective color filters using layers of cholesteric liquid crystals with two different center wavelengths and bandwidths per layer are stacked in two layers to provide colored light for displays. With a two layer stack circularly polarized light of one handedness can be provided. With a two layer stack circulary unpolarized colored light can be provided. With a broadband polarizing filter overlapping other filters in the stack a black matrix can be provided by reflecting all colors and transmitting no light in the overlapping areas. When broadband reflective cholesteric liquid crystals are used two primary colors can be reflected in the same pixel of a display making reflective layers with two reflective portions per layer possible. Color displays having three linear sub-pixels with three primary colors or with four sub-pixels of white, blue, green, and red in a pixel with two colors in a top row and two colors on a bottom row can are made with two colors per layer in two layer stacks. The pixels in the display are arranged such that multiple adjacent sub-pixels in a layer, or row in a layer, with the same color makes the color filters easier to manufacture. Displays using these reflective color filters may have a reflective polarizer for viewing the display at wide angles without color distortion.

摘要： A potentiometer and switch combination including a rotatable control cap positioned over a potentiometer body to form a housing. The cap is provided with an annular flange which abuts an annular shoulder on the body, either the flange or the shoulder being formed from stiffly flexible, resilient material. The body holds the cap in place by means of a post having a chevron at its upper end which mates with a recess in the cap. The cap is positioned to deform the stiffly flexible, resilient material into frictional sealing relation with its abutting member and thereby seal the interior of the housing. The sealing arrangement also introduces a torque which opposes rotation of the cap. The switch includes a conductive strip held by the body, one portion of the strip forming a first contact and another portion forming a spring detent. A cantilever spring blade which holds a second contact adjacent to and radially inward from the first contact urges the contacts together, while a nonconductive blocking member projects downwardly from the cap to separate the contacts when the switch is off. Rotating the cap moves the blocking member out from between the contacts, permitting them to close, and also causes the spring detent to snap against the blocking member and give the operator a positive switch feel.The device is particularly suited for use in a hearing aid.
