Abstract: ELECTRONIC COMPONENT CAP AND SEAL                      Aik Tho (Simon) Chee Wee Soon Kiat ABSTRACT     A cap and seal including a central cap (20) to be positioned over an electronic component such as an inte-grated circuit chip (12), has a spaced upstanding wall or dam (22) which may be staked to the circuit board in assembly forming with the peripheral side wall  (21) of the cap a channel or moat (19).  Bridging means (24) extend between wall (21) and wall (22) onto which is placed a preform ring (30) of solid sealant material. Heating of the assembly, more particularly ring (30), allows melted sealant material to flow under and around bridging means  (24)  to form a confined seal between wall (21), wall (22) and an annular surface (29) on the circuit board surrounding cap wall (21).

Abstract: Abstract of the Disclosure A resilient element which is essentially ring-shaped is arranged within the interior of a screw cap. A fastening end of  he resilient element is inserted into a radially directed bore so that the resilient element with respect to the screw cap is secured against twisting.  The resilient element comprises a warped end in order to form a resilient tongue which, during screwing on the thermostat by means of the screw cap, slips over webs of the thermostat housing.  When unscrewing the screw cap, the resilient tongue of the element abuts against the webs and prevents removal of the thermostat.

Abstract: ABSTRACT OF THE DISCLOSURE     A process is disclosed for removing total reduced sulfur compounds (TRS), especially H2S and mercaptans, from industrial gases wherein substantially dry activated manganese dioxide absorbent particles are fluidized with the industrial gas at an elevated temperature sufficient to effect oxidation of the total reduced sulfur compounds and the absorption of the oxidized compounds on the absorbent particles. In preferred practice, the dried powder containing areas of the oxidized sulfur compounds is recovered as a particle layer in a bag filter unit through which the industrial gas is caused to flow.

Abstract: WEATHERSTRIP MOUNTABLE IN A SLOT    Abstract of the Disclosure A flexible weatherstrip is described, the weatherstrip comprising a member of resilient material and an elongated, flexible anchoring member having a hook-shaped cross-section with two legs defining a cavity therebetween.  The member of resilient material includes a sealing lobe and an elongated anchoring lobe. The anchoring member is less resilient than the resilient material.  A portion of the resilient material lies within the cavity, so that when the anchoring lobe is forced into a receiving groove, the resilient material in the cavity will be compressed.  The anchoring member is adapted to lock in a receiving groove.  The resilient material in the cavity biases the legs of the anchoring member apart into a locking position after the anchoring lobe has been forced into a receiving groove and the resilient material in the cavity then expands after having been compressed.

Abstract: THREE-WAY VALVE FOR AUTOMATIC SEQUENCING OF FLUID FLOW  ABSTRACT OF THE INVENTION           A three-way valve for automatic sequencing of fluid flow from a syringe into an IV administration set comprises a housing which forms a fluid chamber having a first and a second inlet and an outlet.  A sleeve having a fluid passage-way normally closed by a check valve is slidably disposed within the fluid chamber for reciprocal movement between a first position and a second position for respective fluid sealing engagement with the first and second inlets.  With the sleeve in the second position, fluid flows through the chamber from the first inlet to the outlet.  Engagement of a syringe with the second inlet urges the sleeve into the first position to permit fluid flow from the syringe into the second inlet and through the chamber to the outlet.  Upon emptying of the syringe, the syringe plunger seals the second inlet and urges against a probe that opens the check valve to permit resump-tion of fluid flow from the first inlet to the outlet.

Abstract: Abstract A sight tube assembly, in combination with a sensing instrument, such as an optical pyrometer, for use in continuously monitoring the temperature of the first row of rotating blades in large gas turbines, particularly the type used in industry.  Temperature data received by the pyrometer unit is fed to a control circuit, which regulates fuel input to the turbine to control the firing temperature.  The key to obtaining reliable blade temperature data in the practice of this invention is the position of the sight tube in the tur-binej which enables the pyrometer to "view" the rotating blades along a direct line of sight that penetrates a hot gas duct, but not the turbine section of the engine.
