  • Patent number: 5934540
    Abstract: A solder immersion chamber in a solder crater/leveler includes a solder manifold having upper and lower solder chambers, from which solder is directed onto the top and bottom surfaces of printed circuit boards conveyed therebetween. The solder immersion chamber has a pair of driven rollers at either end thereof for conveying the printed circuit boards through the solder immersion chamber, and for damming and holding the molten solder within the solder immersion chamber. A pair of oil weirs is provided adjacent either side of the upper solder chamber for continuously flowing oil to flood the top surface of the molten solder in the solder immersion chamber. A skimmer skims oil from the top surface of the molten solder, and returns the separated oil to the pair of oil weirs.

  • Patent number: 5935426
    Abstract: A totalization meter system for a water treatment device, the device having an inlet aperture and an outlet aperture, and a channel for channeling water between the inlet and outlet apertures. A flow reactive device is positioned in the channel and is exposed to the flowing water, and a signal generating member is positioned on the flow reactive device. A switch is positioned proximately to the flow reactive device, and is sensitive to the proximity of the signal generating member. The switch is able to communicate electric signals indicative of the motion of the signal generating member. A resettable processor having a performance threshold programmed therein and an output device is included. The microcontroller is in electrical communication with the switch for receiving electrical signals from the switch. The switch is capable of sensing the characteristics of the flow reactive device and communicates electrical signals representative of the characteristics to the microcontroller.

  • Patent number: 5865378
    Abstract: A flexible shower arm assembly that allows the user to repeatably adjust the position of the shower head in three dimensions by configuring the shape of the shower arm attached between the water source, such as a shower pipe, and the water dispenser, such as a shower head. The particular position of the shower head, and the direction of the shower spray, can be modified by re-configuring the shape of the shower arm. The flexible shower arm holds the desired position until modified by the user. The flexible shower arm is sealingly attached to the shower pipe by a pipe connector nut, and is sealingly and pivotally attached to the shower head by a connection structure. The flexible shower arm assembly includes an elongated flexible member defining a fluid transfer path, the flexible member having a first end and an opposite second end.

  • Patent number: 5860451
    Abstract: Apparatus for providing an admixture of first and second fluids has a first body having opposite ends, a chamber between such opposite ends, an inlet for first fluid into that chamber, and an aperture for the admixture at an end of that chamber. That apparatus also includes a second body having an inlet aperture for second fluid spaced from the first body, an outlet aperture spaced inside the chamber from the aperture for the admixture, and a fluid flow channel decreasing in cross-sectional area from the inlet aperture spaced from the first body to the outlet aperture inside the chamber between opposite ends of the first body.

  • Patent number: 5846418
    Abstract: The point-of-use water treatment system for treating water to be dispensed from a container includes a filter media positioned adjacent a water input opening of the container, through which water is filtered into the container. The filter media includes a water soluble disinfectant positioned thereon or therein, with the preferred disinfectant tetraglycine hydroperiodide, chloramine-T, or calcium hypochlorite. The disinfectant dissolves in the water as it passes through the filter, and reduces the biological activity of microbiological agents in the water. A point-of-use method of the present invention which reduces microbiological contamination in a predetermined volume of water to be dispensed from a container which utilizes a filter media containing a water soluble disinfectant impregnated thereon is also disclosed.

  • Patent number: 5829242
    Abstract: The modulus of stretch af a fibrous rope is reduced by impregnating a pluity of spaced-apart segments of the rope with an epoxy plastic thereby to reduce the modulus of stretch of the segment equal to zero after curing the plastic. The overall modulus of stretch of a re-manufactured rope taken as a whole is proportional to the ratio of the length of an impregnated segment relative to a unit length of the rope.

  • Patent number: 5788832
    Abstract: An electrochemical gas sensor having a temperature sensitive element such as a thermistor arranged within the gas sensor in a temperature insulative fashion for preventing any variations in the temperature of the applied gases to be sensed to be immediately conveyed to the temperature sensitive element thereby providing accurate temperature compensation signals to be combined with the generated sensor electrical output signals. The temperature sensitive element or thermistor is mounted in a heat sink to the expansion membrane of the gas sensor to be responsive only to changes in the temperature variations imparted by the sensor electrolyte and not by the variations in the temperature of the gas sensor body and associated elements thereby providing correct temperature compensation signals without error producing time delays.

  • Patent number: 5750892
    Abstract: A laminar flow element for use in flow metering devices has a laminar flow element plug with an upstream end and a downstream end and a linear extent between the upstream end and the downstream end, the laminar flow element plug configured to be positioned within a base cavity with the upstream end oriented toward the direction of flow, and sensor taps through walls of the base cavity positioned inboard of the laminar flow element plug so that entrance effect is eliminated, error due to flow cross-sectional area differential is eliminated, and orifice effect is minimized, to produce a laminar flow with linear pressure drop across the sensor taps as a function of flow rate. Coaxial laminar flow guides are fixed coaxially about at least a portion of the length of the laminar flow element plug to increase the number of flow passages to enable linear measurements of higher flow rates.
