Abstract: A container having two channel-like members which mate with one another to form an enclosure and a plurality of threadable clip members attached to the channel-like members, each threadable clip member having a threadable slot where (a) the slots of certain ones of the clip members respectively receive predetermined edges of the channel-like members and (b) screws or the like may be threaded in the slots of the remaining ones of the threadable clip members, the screws extending through holes provided in the channel-like members to thereby secure the latter members together.

Abstract: A desolderer and heater assembly therefor wherein the heater assembly includes at least a heating element and a solder transfer means where the forward end of the solder transfer means is adapted to receive a desoldering tip and where the thermal characteristics of the rear end portion of the solder transfer means are such that the heater element raises the rear end portion of the solder transfer means to a solder melting temperature shortly after the tip reaches this temperature. The desolderer includes a solder collection chamber into which molten solder is ejected from the solder transfer means where the solder collection chamber may be disposed either inside or outside the desolderer handle. Various embodiments are described whereby the heater assembly may be adapted to receive a seal mounting member so that the forward end of the solder collection chamber can be sealed at a surface which is removed from the path the molten solder traverses through the solder transfer means.

Abstract: The inlet and discharge valves of a pump are each comprised of a circular valve plate centered in a circular cutout in a flat valve sheet. Diametrically opposed webs join the valve plate to the main body of the valve sheet and perforations in the webs provide both, spring action and allow for air passage.

Abstract: A collapsible container having two channel-like members which mate with one another to form an enclosure and two U-shaped brackets having inwardly facing grooves for receiving the edges of the channel-like members to secure them together. A method for forming the channel-like members from sheet metal or the like and the U-shaped members from elongated bars.

Abstract: A solder removal device has air under pressure supplied thereto. The device has a hollow handle in which is disposed a Venturi structure for creating a vacuum where the vacuum is applied through a solder collection chamber also disposed in the handle and a solder extraction tube in communication with the solder collection chamber and extending outside of the handle. The air discharged from the Venturi structure is directed around the solder collection chamber and out an opening in the handle whereby heat is removed from the solder collection chamber, the heat having been generated by hot air and solder sucked into the chamber. Hence, the device may be used continuously for solder extraction without discomfort to the operator's hand.

Abstract: A desoldering device is disclosed which can be connected to a plurality of different pencil type soldering irons having a removable soldering tip. The device comprises a head member with an adaptor which can be secured to the soldering iron after the soldering tip has been removed. The head member has a through passage in which is positioned a hollow tube and copper tip. A base member is secured to the hollow tube and supports a glass container for receiving softened solder. A source of suction is connected to the base member for drawing the softened solder through the hollow tip and tube and depositing it in the glass container.

Abstract: A spacer grid for nuclear fuel rods is formed of generally identical metal straps arranged in crossed relation to define a multiplicity of cells adapted to receive elongated fuel elements or the like. The side walls of each cell have openings for intercell mixing of coolant and tabs from edges of the openings defining helical coolant deflectors in the cells. Tabs from adjacent side walls are fixedly secured together to provide rigidifying flanges for the grid. Spring fingers at the ends of the cells provide for holding fuel rods against fixed stops.
