  • Patent number: RE30276
    Abstract: Stoppers are separated from tubes they close by suspending a stoppered tube by its stopper, placing the suspended tube in a swinging bucket centrifuge, subjecting the suspended tube to centrifugal force.This may be accomplished by adapting a test tube rack to be placed in a centrifuge's swinging bucket type carrier. The rack is a two piece unit having upper and lower members that are separable. The test tubes use stoppers having an enlarged portion with a diameter which exceeds that of the test tube such that the tubes may be suspended from the upper member by their stoppers. The rack has a height which exceeds that of the test tubes such that when the rack with the tubes suspended therein are subjected to centrifugal force, the tubes withdraw from the stoppers. This leaves the stoppers positioned on the upper surface of the upper member. If now the upper member is lifted away, the stoppers are removed leaving the unstoppered test tubes positioned in the lower member of the rack.

  • Patent number: 4203185
    Abstract: A method of sealing tube plate apertures, e.g. in heat exchangers, and a repair set for use therein. It is known to seal a tube plate aperture by mounting a capped tube member therein. A disadvantage of the prior method is that the sealed aperture contains a fluid with a temperature different from that of the fluid in the non-sealed tube plate apertures, which results in stresses being generated in the tube plate and an increased danger of leakage. According to the invention this disadvantage is overcome by sealing the aperture in such a manner as to form an insulating space over the major part of the thickness of the tube plate.

  • Patent number: 4203191
    Abstract: Disclosed is a process and apparatus for assemblying spiral wound gaskets into gauge rings. The process comprises exerting inwardly directed radial forces on the exterior of the spiral wound gasket, causing it to decrease in diameter sufficiently to slip into the gauge ring. The apparatus comprises a holder having a tapered opening and a mandrel which is adapted to engage the periphery of the gasket. As the mandrel with the gasket in place is pushed downwardly through the tapered opening, the mandrel's diameter is decreased and consequently the outer diameter of the spiral gasket is decreased. Means is provided to hold the gauge ring in position immediately adjacent the minor diameter end of the tapered opening in the holder, whereby as the mandrel pushes the gasket out of the minor diameter end it is immediately placed in the hole in the gauge ring where the forces are then released. The gasket is then free to expand outwardly to a tight fit into the gauge ring.

  • Patent number: 4203192
    Abstract: A vibrating wire stress meter and the method used to clamp its wire in position. The wire is highly tensioned diametrically across the sides of a hollow metallic cylinder and held there by two anchor tubes. A wedge and platen assembly in turn hold this cylinder in a rock borehole such that small stress changes in the surrounding rock cause the diameter of the cylinder to slightly change. This cylinder variation is transmitted to and measured by the preloaded wire by noting variations in its frequency or period of vibration. To cause the wire to vibrate a coil, magnet, and yoke are used as a plural pole electromagnetic plucker.Clamping of the wire is accomplished by highly tensioning the wire between two opposite hollow tubes that are seated in opposite aligned countersunk holes of the cylinder and then extruding the steel tubes around the wire. The wire extends through holes of those hollow tubes as well as the aligned holes in the cylinder walls which are diametrically opposite each other.

  • Patent number: 4203194
    Abstract: A plurality of porous valve-metal pellets are suspended by their anode riser wires from a holding bar. After the conventional steps of anodically forming an oxide film over the surfaces of the pellets and depositing a solid electrolyte and a metallic counterelectrode over the film, an insulative resin layer is applied over the pellets by an electrostatic fluidized powder-bed coating step, selective air-stream powder-removal steps and heat curing steps. Anode and cathode end cap terminals are subsequently formed over opposite ends of each pellet, preferably by applying and curing a silver loaded paint, curing the paint, nickel immersion plating over the silver and cladding the nickel film with solder.

  • Patent number: 4203196
    Abstract: A tool for simultaneously inserting each of a plurality of wires in respective non-deforming insulation piercing terminals disposed in a terminal retaining body. The terminal retaining body is supported in the tool so that each terminal is aligned with a guide slot through which the wires are forced by the action of insertion tabs. The ends of the wires are retained in coil springs which are coupled to releasing handles so that the springs may be extended to facilitate removal of the wires. As the insertion tabs are forced through the guide slots, a cutting member disposed in each of the slots cooperates with an edge of the insertion tabs to cut the wire at a predetermined point. The tool is adjustable to accept terminal retaining bodies of various shapes and sizes.

  • Patent number: 4203198
    Abstract: A heating panel array is of a "sandwich" configuration and employs a serpentine resistive array fabricated from a metal foil and disposed between two sheets of fiber glass cloth, all of which are secured together by a binder having stable properties in the presence of heat generated when said array is energized. The binder contains colloidal silica spheres of submicron diameter. Methods for fabricating the panel are described which enable fabrication of a multiplicity of panels using selective etching and silk screening techniques. The fabrication process assures the absence of impurities in the heater panel construction and in conjunction with the binder enable the panel to operate without smoking and aromatic problems.
