Abstract: A method and apparatus are disclosed for testing the operation of solenoids in a safety system by bypassing the solenoid operated pilot valve and applying a pneumatic control source to the system being tested through a bypass line while demonstrating the operation of the solenoid operated pilot valve for such a system using a test pressure source and a test input through the testing system. The system thereby permits continued operation of the process system while verifying proper operation of the safety system.

Abstract: A composition for regenerating spent weak cation exchange resin and a method of utilization including salts of .alpha.-hydroxy carboxylic acids or o-hydroxy benzoic acids. The following steps are employed in cyclically regenerating polycarboxylic acid cation exchange resins: (a) utilizing a charged or alkali metal salt of polycarboxylate acid cation resin to soften water; (b) regenerating the spent resin in one step with an active regenerant of the .alpha.-hydroxy carboxylic acids or o-hydroxy benzoic acids to produce spent regenerant; (c) precipitating the polyvalent hard ions in the spent regenerant with sodium or potassium carbonate to reform the active regenerant; (d) separating the precipitate; and (e) concentrating the dilute active regenerate solution to its approximate initial concentration and recovering of water for process rinses.

Abstract: A substantial portion of the material at the pn junction (27) of the photodiode (37, 41) having an implanted region extending to a surface thereof is selectively removed (39), leaving a very small junction region (35, 43) with the remainder of the p-type (23) and n-type (25) material of each photodiode being spaced apart or electrically isolated at what was originally the junction. In the ion implanted n-type on p-type approach, the majority of the signal is created in the implanted n-type region while the majority of the noise is generated in the p-type region. By selectively removing p-type material, n-type material or both from the pn junction of the diode or otherwise electrically isolating most of the p-type and n-type regions from each other at the pn junction and thereby minimizing the pn junction area, noise is greatly reduced without affecting the signal response of the photodiode.

There is further disclosed a new and useful foundation assembly for a perimeter beam which is comprised of a flexible fabric container, situated on ground surface, that is furnished with a cementitious material having a stanchion partially embedded within the cementitious material.

Abstract: A network (10) includes a repeater (12) that can service data devices that operate using different communications protocols. The data devices (18, 20, 22) couple to the ports (34) of the repeater (12), and operate using a first communications protocol in a first domain (14). The data devices (26, 28, 30) also couple to the ports (34) of the repeater (12) and operate using a second communications protocol in a second domain (16). Information on the operation of a port (34) may be displayed using one port indicator (202) or two port indicators (300, 302).

Abstract: A trailer 10 has a frame 12 with cross members (20). A bottom rail (62) is secured to the frame 12. A top rail (130) is supported by the frame. A plurality of extruded panels (70) are attached to the bottom rail 62 and the top rail (130) to form side walls (22 and 24) and a front wall (26). Each panel (7) is a hollow member with an outside wall 72, and inside wall (74), a first end wall 76 and a second end wall (78). A first outside flange (80) and a first inside flange (82) are integral with the first end wall (76). A second outside flange (90) and a second inside flange (92) are integral with the second end wall (78). When plural panels (70) are connected together to form a trailer wall (22, 24, or 26) first inside flanges (82) are between second inside and outside flanges (90, 92) and second inside flanges (92) are between first inside and outside flanges (80, 82). A passage (99) is formed between adjacent first and second inside flanges (82 and 92) and end walls (76 and 78).

Abstract: An operator to host communications interface for managing a manual data storage library. A host processor controls Peripheral Data Storage Devices (PDSDs) in the library. Displayed operator interaction fields are presented by a graphical user interface on the screen of a display device connected to a library manager controller. Library manager program code loaded in program memory in the library manager controller is provided with interface logic, for communicating with external devices, as well as the PDSDs through the host processor. The operator communications interface is an integral component of the library and thus may be used for: alerting an operator of the need to mount or demount a particular data medium; alerting an operator with coherent and succinct messages thus improving the quality of messages provided to operators; and alerting an operator with a minimum number of messages.

Abstract: A ventilator having a one-piece plastic base with integral tubular member having a through passageway for flow of an exhaust gas stream. The tubular member is preferably molded simultaneously with the base, rather than glued, so that the base and tubular member assembly comprise not only a sealed tubular member, but provide a single, seamless part. Thus, moist air cannot leak out of the air flow path between the interior and exterior of a wall or roof. The ventilator is also provided with a screen and a flapper type lid for the tubular member. The flapper lid seals the outer end of the tubular member against inflow of outside air at those times when there is no exhaust gas stream impinging against the flapper so as to keep the flapper in the open position. The ventilator may be provided in a variety of colors by pigmentation of the plastic to be molded into the ventilator.

Abstract: A method and apparatus for molding polymeric structures in vivo is disclosed. The structures comprise polymers that may be heated to their molding temperature by absorption of visible or near-visible wavelengths of light. By providing a light source that produces radiation of the wavelength absorbed by the polymeric material, the material may be selectively heated and shaped in vivo without a corresponding heating of adjacent tissues or fluids to unacceptable levels. The apparatus comprises a catheter having a shaping element positioned near its distal end. An emitter provided with light from at least one optical fiber is positioned within the shaping element. The emitter serves to provide a moldable polymeric article positioned on the shaping element with a substantially uniform light field, thereby allowing the article to be heated and molded at a desired treatment site in a body lumen.

Abstract: Light-emitting bipolar devices consist of a light-emitter formed from an electroluminescent organic light-emitting material in contact with an insulating material. The light emitter is in contact with two electrodes that are maintained in spaced apart relation with each other. The light emitter can be formed as an integral mixture of light emitting materials and insulating materials or as separate layers of light-emitting and insulating materials. The devices operate with AC voltage of less than twenty-four volts and in some instances at less than five volts. Under AC driving, the devices produce modulated light output that can be frequency or amplitude modulated. Under DC driving, the devices operate in both forward and reverse bias.

Abstract: A device for retrieving golf balls from water hazards, which includes a main body resembling a scoop with a handle holder to which a pole-like handle may be attached. The main body has two parallel oppositely positioned end walls, and preferably three slots that can retain golf balls while allowing water to pass through as the invention is moved along the bottom of a water hazard to retrieve the balls. Rounded end portions of the slots are shaped so that the balls will tend to fall into them, rather than rolling back out of the interior of the main body. In the preferred embodiment, two center strips run between slots. Two end strips run between slots and the end walls to which they are connected. The strips and end walls are joined by a top cross strip and a bottom cross strip. The handle holder includes preferably a widened portion of the top cross strip, to which are perpendicularly joined two parallel upright members, between which preferably two parallel bolts are inserted, to hold the handle in place.
