Abstract: A process for producing boron compounds represented by general formula (1) which comprises the first step of producing a metal borate represented by general formula (4) through reactions of a lithium, magnesium, or a lithium compound with a compound represented by general formula (2) and a compound represented by the general formula (3) of R2 -Y and the second step of adding an onium halide represented by the general formula (5) of Z+ X- to the metal borate (4) to cause the borate to undergo an ion-exchange reaction (the symbols in the formulae having the same meanings as in the specification).  This process can provide high-purity boron compounds represented by general formula (1) useful as a photopolymerization initiator or a light-absorbing decoloring agent in high yields in a short time.

Abstract: Heart valve leaflet selection methods and apparatuses which subject individual leaflets to loads and measure the resulting deflection to more reliably group leaflets of similar physical characteristics for later assembly in prosthetic heart valves. The deflection testing may be accomplished using a variety of test set ups which are designed to impart a load on the leaflet which simulates the actual loading within a heart valve. The results from a number of deflection tests are used to categorize individual leaflets, which data can be combined with other data regarding the characteristics of the leaflet to better select leaflets for assembly into a multi-leaflet heart valve. In one embodiment, the deflection test is combined with an intrinsic load test, and leaflets having similar deflection and intrinsic load values used in the same heart valve. One apparatus for testing the leaflets includes a frame for securing the arcuate cusp of the leaflet while the straight coapting edge remains free, to simulate the actual leaflet mounting configuration within the heart valve prosthesis. The frame may include a lower portion having a recess for the leaflet and plurality of receptor holes around the peripheral edge of the recess, and an upper portion having a plurality of needles which extend downward through the leaflet and into the receptor holes and secure the edges of the leaflet.

Abstract: A low-cost superfluorescent fiber souce. A gain medium in a length of optical fiber is pumped in counter-propagation by a pump source, producing superfluorescent radiation. The pump source is coupled to the fiber by a first coupler, disposed forward of the gain medium, that selectively transmits the pump signal in the backward direction, and the superfluorescence in the forward direction. A second coupler is disposed backward of the gain medium, selectively transmitting the backward propagating superfluorescent radiation along a first path and the pump signal along a second path, the pump signal is absorbed in the second path by a high-attenuation fiber, to avoid feedback to the pump laser, and the superfluorescent is reflected in the first path back toward the source output.   Advantageously, this source can be realized with readily available optical , components that are easy to assemble and do not require any alignment.

Abstract: A closure operating device comprises a control unit for controlling a power actuator operatively connected to a closure to selectively open and close the same. The control unit and the power actuator are mounted to a casing adapted to be mounted on a wall. The casing defines an interior space which is normally closed by a lid which defines itself a compartment for receiving parts of the control unit. A limit switch mechanism is mounted in the compartment for automatically interrupting power transmission to the power actuator when the closure reaches a fully open position or a fully closed position thereof. The limit switch mechanism includes a pair of switch actuators threadably engaged on a shaft. The switch actuators are normally locked against rotation by an anti-rotation member. The anti-rotation member is adapted to be independently disengaged from the switch actuators to prevent accidental displacement of one of the switch actuators while the other one is being manually adjusted.

Abstract: A method in a data processing system for providing content from a distributed database to a client. In a preferred embodiment, a transcoding proxy server receives a request for content from a client machine. The transcoding proxy server retrieves the content from an originating server. The retrieved content is provided in a first format type. In response to a determination that an increase in efficiency would be obtained by allowing the client to process the content in the first format type prior to transcoding the content into a second format type, the transcoding proxy server sends the content to the client in the first format type. Furthermore, in response to a determination that the client does not have content processing software for processing the content in the first format, the transcoding proxy server sends content processing software for the first format type along with the content in the first format type to the client. The transcoding proxy server then transcodes the content from the first format type into the second format type and sends the content in the second format to the client.

Abstract: A below-deck solar blanket roller assembly is installed below the deck of a pool. The roller assembly includes a rotatable roller shaft for rolling and unrolling a solar blanket and a non-rotatable protective casing which surrounds the roller shaft. The roller assembly is intended to be installed below the deck of a pool. This invention at least partially overcomes some of the disadvantages of typical solar blanket rollers that are installed on the surface of the pool deck, such as inconvenience in moving the entire above-deck assembly away from and back to the pool area. The below-deck solar blanket roller assembly provides an aesthetically pleasing and safe alternative to solar blanket roller assemblies installed above the pool deck.

Abstract: A coiled tubing injector includes two chains mounted for continuous, opposing rotation and aligned to grip between the continuous tubing. Behind a portion of each chain is a straight skate that presses gripper elements on the chain against the tubing as it passes between the chains. The skate includes a beam. Rollers are mounted on carriers, and the carriers slide into slots formed on the beam. A resilient pad is placed between the carriers and the beam. The gripper elements roll over the rollers as they are being pressed against the continuous tubing. Dimensional variations in gripper elements, rollers, and the roller carriers that may otherwise cause grippers to be out of alignment are accommodated by compression of the pad. Furthermore, the last roller at each end of each skate is mounted for pivoting against a spring in order to deflect as gripper elements turn into, or out of, alignment with the skate.
