Abstract: System for mounting screen and other panels in vibrating and other screening apparatus in which longitudinal channel members interposed between laterally adjoining panels and anchored to apertured longitudinal supports, have spaced normally upright flexible sides each yieldably flexing inwardly in response to pressing of a panel edge thereagainst for seating the edge in an external groove in the channel side, the channel member containing a longitudinally coterminous cavity opening upwardly through a relatively restricted slot, and the panel edge being releasably lockable in the channel groove by a T-shaped lock member having a stem insertible in said cavity through said slot for forcing the flexed side to return to upright edge-locking position. The system also includes clamps on sides of the apparatus for clamping contiguous outer sdges of screen panels thereto, reinforcing of profile wire screens by socketing projected ends of their tie rods in molded screen edges, and for vibrating screening apparatus, dams mounted at predetermined longitudinal intervals for retarding flow through the apparatus.

Abstract: 2-Benzothiazolyl tetrazolium salt compounds have been found to be characterized by a reflectance spectrum exhibiting an extended plateau above about 600-650 nm. Such compounds are useful as chromogenic indicators for reducing substances such as NADH. The reflectance plateau confers improved accuracy to analytical assays, particularly for the determination of analytes of medical diagnostic significance, in which a colorimetric response on a reagent carrier matrix is measured by reflectance.

Abstract: The decision feedback decoder of the invention receives sequentially sampled values of a signal waveform corresponding to data bits transmitted by a channel. A magnitude comparator (16) compares the sampled values to a threshold and based on each comparison it provides subsequent decisions determining the values of the corresponding data bits. A predetermined number of previous decisions is stored and applied to first and second threshold adjustment circuits (26,28). Each circuit adjusts the threshold depending on the respective values of the previous decisions, while the first circuit provides the adjustment based on an assumption that the next decision to be made will have a first signal value and the second circuit provides the adjustment based on an assumption that the next decision will have a second signal value. When that next decision becomes available, it is utilized to select the correct adjusted threshold value for the next comparison by the magnitude comparator.

Abstract: A medical device for endoscopic access of a body cavity and a method of percutaneously placing inner and outer access sheaths of the device into the body cavity. The medical device includes inner and outer access sheaths and a dilator which is inserted into the outer sheath and has a shoulder or a shoulder piece for abutting against the proximal end of the outer sheath. The device also includes a wire guide that is percutaneously inserted into the body cavity via an introducer needle. The dilator and outer sheath are placed over the wire guide to dilate the puncture site and introduce the dilator and outer sheath into the body cavity. The dilator comprises an elongated cylindrical member having a passageway opening distally from the conically-shaped distal end and from an outside lateral wall of the dilator about the proximal end. The dilator also includes an end cap which is utilized to force the dilator and the outer sheath through the puncture site and into the body cavity. After positioning in the body cavity, the dilator and wire guide are removed through the outer sheath. The inner sheath is then inserted through the outer sheath into the body cavity. The proximal ends of both the inner and outer sheaths include seals for maintaining insufflation of the body cavity. The inner sheath includes a shoulder piece having a chamber and a side port for connection to an insufflation gas line.

Abstract: A switching architecture with identical switching nodes having a topology which allows for multiple paths between any two endpoint switching nodes without intervening switching nodes being involved in call control on those paths. This architecture is made feasible by a new type of link, the flexible rate interface (FRI) link. The FRI link has its own signaling channel distinct from the signaling channel of a standard link and is transparent to intervening switching nodes. Only endpoint switching nodes are aware of the existence of the FRI link with respect to call control. A standard protocol is utilized on the signaling channels of both the standard link and the FRI link. Advantageously, the standard link may be an ISDN link and the standard protocol may be the ISDN protocol. An FRI signaling channel of the FRI link may be established by using any of the following: a B channel of a standard ISDN link, standard ISDN user information transport facilities, or a logical link of a D channel of a standard ISDN link. In combination with the FRI signaling channel, the FRI link may utilize B channels from a number of standard ISDN links for FRI B channels.

Abstract: Inefficiency in heat exchange in an evaporator for a refrigeration system due to maldistribution of incoming refrigerant may be reduced in a structure wherein a plurality of hydraulically parallel flow paths are defined by tubes (20) having ends (84) in the interior of a header (10). Refrigerant inlets (70, 72) are provided for the header (10) at opposite ends (62, 64) thereof to generate streams (78, 80) of incoming refrigerant which impinge upon one another to dissipate the kinetic energy and/or momentum of the streams (78 and 80) which in turn results in an improved distribution of the refrigerant within the header (10). Refrigerant outlets are provided for a header. The outlets are at opposite ends thereof to generate two streams of outgoing refrigerant which reduces outlet resistance and thus provides for more uniform flow of the refrigerant.
