Abstract: ABSTRACT OF THE DISCLOSURE     A method of etching aluminum by applying an alternating electric current to aluminum which is in contact with an electrolyte containing hydrochloric acid, in which the alternating current has a symmetrical waveform wherein the current rises rapidly from zero to a maximum, then subsequently decreases rapidly in a first stage to an intermediate value which is about one-third to about one-half of the maximum, and thereafter decreases more slowly to zero in a second stage.  Thereafter the current rises and falls in the opposite direction with the same waveform.  The ratio of time of the second stage to time of the first stage of the waveform is in the range from 1 to 6.  By this procedure higher capacitance values of the etched aluminum are ob-tained in comparison to prior procedures.

Abstract: ABSTRACT OF THE DISCLOSURE           A temperature-controlling system for a fuel supply line characterized by a simple and inexpensive thermostatically controlled valve positioned within the flow, and sensitive to the temperature, of the fuel before it has been mixed with bypassed and heated fuel.  The valve modulates the flow bypassed through a heat ex-changer, which flow later joins the stream of fuel which has not been bypassed and heated.

Abstract: ABSTRACT OF THE INVENTION     A fire-safe valve actuator which cooperates with a bolted bonnet type valve to define a bolt chamber with an exterior shroud supporting the actuator housing and providing a substantially im-perfect barrier to prevent an external fire from coming into di-rect contact with the bolts or studs and nuts that connect the bonnet to the valve body.  The bolt chamber may also be filled with an insulation material.  The actuator may have a return spring con-nected to the actuator stem through a bearing so that the winding and unwinding of the spring does not result in any substantial torque being applied to the actuator stem.  Similarly, any diaphragm in the actuator can be connected to the actuator stem by a bearing so that rotation of the stem will not impart torque to the dia-phragm.  Furthermore, a stop can be provided limiting outward move-ment of the stem under the influence of the spring and by further providing a suitable sliding engagement between the diaphragm-actuator housing and the stem, the actuator housing and diaphragm can be readily removed from the balance of the actuator without bleeding the line pressure down.

Abstract: ABSTRACT OF THE DISCLOSURE   An improvement is provided in a fluidized bed apparatus intended to fluidize solid particles by means of ascending stream gas.  The improve-ment is intended to reduce solid particles en-trained from the apparatus, and comprises the disposition of an internal member in the free board of the apparatus so that the projected area ratio is not less than 0.8, and the opening projection to the free board cross-sectional area is within 0.3 to 0.9.  This substantially increases the productivity of the reactor per cent volume, by  significantly reducing the entrainment of solid particles from the reactor.

Abstract: ABSTRACT      VALVE SUITABLE FOR CONTROLLING TEEMING               FROM FURNACE TAPHOLES           Metal flow from furnace taphole to a pouring trough is controlled by a valve interposed therebetween, the valve having a stationary orificed valve plate and a companion slide plate for closing or opening the orifice to flow.  An actuating beam member forming part of a parallel motion linkage extends upwardly and obliquely from the slide plate, the actuating member being thrust against the slide plate by a swinging spring strut of the linkage.  A ram connected to the linkage via a crank, a shaft and a pivoted lever displaces the linkage when extended or contracted and this moves the actuating member along a predetermined path, its oblique attitude being preserved, to open or shut the valve.

Abstract: STERILIZED STORAGE CONTAINER  Abstract A container is provided having a base and a lid with the base being formed relatively flat but with the center portion of the base raised so that condensation within the container will flow to the edges and out of the container when the lid is not in a closed position.  The lid is held partially open by an actuator pin connected to an expandable chamber which will expand in response to the pressure drop at the end of the sterilizing cycle to withdraw the pin and allow the lid to close onto the base. In this way, the container is closed after the contents have been sterilized and after any condensation within the container has been allowed to drain, but before the container is exposed to unsterile environment.  A valve controlling the flow of steam into the expandable chamber closes when subjected to the high temperature steam, thus capturing the steam which eventually expands to cause withdrawal of the pin. The container lid and base together with a gasket permit steam to be withdrawn from the container but prevent air flow into the container once the lid is closed.  A vacuum created within the container at the end of the sterilizing cycle holds the container lid in place.        In another arrangement, an expandable chamber is em-ployed to cause the container to be sealed at a predetermined pressure after the container has been subjected to a final vacuum in an autoclave cycle but before the container is removed from the autoclave. The lid is first held open by one end of a pivotally mounted lever. A temperature triggered, pressure re-sponsive expandable chamber is employed to pivot the lever, withdrawing the end of the lever which had been supporting the lid and pivoting the second end of the lever into a lid supporting position.  When the pressure surrounding the expandable chamber is increased at the end of a vacuum cycle in an autoclave, the expandable chamber contracts, allowing a spring to pivot the lever and withdraw the second end of the lever from supporting the lid, thus allowing the lid to fall and seal on the base.

Abstract: ABSTRACT          A fuse holder clip for snap-in insertion into a parallel array fuse holder block features a terminal lug configured in the form of a right-angle strap of length such as to allow mechanical and electrical engagement to a similarly configured adjacent clip disposed along one side of the array.  Complemen-tary engaging means, preferably in the form of a hollow rivet at the right-angle bend of the strap, and a matching hole at the outboard and of the strap permits riveting engagement of a arbitrary number of such clips, whereby such clips become electrically interconnected by a common bus.  The snap-in feature of the clips permits removal and reconfiguration of terminal groupings along a given edge of the fuse block at will.  Use of the hollow rivet facilitates high current lead attachment to the bus by an eyelet lead lug and a self-tapping screw. A support shelf unitary unitary the mounting block and disposed to give close support to the junction region of the two straps prevents significant deformation of the bus during such lead attachment. The shelf also provides additional protection against accidental deformation of the bus structure to touch the mounting surface on which the fuse block is mounted.

Abstract: SIDE POCKET MANDREL WITH IMPROVED ORIENTING MEANS          Abstract A side pocket mandrel having an orienting sleeve therein with improved guide surfaces for more reliably orienting a kickover tool with respect to the mandrel preparatory to installing a flow control device in or removing such a device from the mandrel's offset receptacle bore. background of the Invention Field of the Invention This invention relates to gas lift apparatus and more particularly to side pocket mandrels for use in gas lift wells.    Description of the Prior Art Side pocket mandrels with orienting means therein for orienting a kickover tool used in installing well flow control devices in or removing them from their offset receptacles have been used for many years.  Side pocket mandrels and kickover tools therefor have been supplied by a number of suppliers in the industry.  Kickover tools from one supplier may not work well in the side pocket mandrels of another supplier even though such kickover tool may have been intended for use in such side pocket mandrel.  It has been desirable to provide a side pocket mandrel which would be compatible with virtually any kickover tool designed for use with such mandrel and to minimize difficulties arising from such mismatching.    The orienting means in side pocket mandrels have been in the form of a sleeve surrounding the bore through the side pocket mandrel, this sleeve being provided with a pair of symmetrical guide surfaces generally helical in shape leading from a point at the lower end of the sleeve upwardly to the lower end of a longitudinal orienting slot.  In some cases
