Patent CA-1186561-A (CA)
Title: Aerodyne
Inventor: BOEDER DIETER
IPC: F42B12/60
Filed: 1982-10-22
Granted: 1985-05-07
Abstract: ABSTRACT The invention relates to an aerodyne for the transportation of a plurality of disposable loads adapted to be ejected at a predetermined point along the flight path.  The aerodyne has a tubular casing enclosing a disposable-load area and a device for ejecting the loads. The tubular casing consists of various segments connected detachably to each other and forming a cylindrical envelope.  The cylindrical configuration is achieved by elastically deforming the segments so that they interengage under preload.  Individual segments comprise hooked extensions which engage, after the manner of tongs, around a rod and may  thus be braced together.  Movement of the rod in relation to the hooked extensions unlocks the segments from the casing, allowing them to spring apart under their preload and to thereby separate from the aerodyne prior to ejection of the disposable load.

Abstract: ABSTRACT An oil well packer retriever has a packer miller 6 which has a series of fin-like blades radiating from a central tube string 2.  The blades are faced with tungsten carbide and in use these mill away the packer allowing it to drop under gravity.  A packer catcher 7 catches and retains the fallen packer for removal from the well.  The weight of the packer held by the catcher 7 bears on a shear collar 8 which is secured to the central string 2 by one or more shear bolts the combined shear strength of which is known.  Should the shear stress on the collar 8 exceed that which has been preselected by the number and/or material of the shear bolts, the bolts shear releasing the collar 8 which drops out of engagement with the catcher 7 allowing the retriever to be withdrawn from the packer.  The packer retriever can under normal condi-tions mill out find extract several packers without re-dressing the blades and replacing the catcher.

The valve body is spring loaded whereby said pump is pressure actuated.  The discharge chamber comprises an open ended housing mounted on the container and a cooperating piston having an open ended bottom mounted therein, the spring loaded valve body being positioned between the housing and the piston.  The closed end of the housing is provided with an upstanding stem.  The lower end of the valve body has an open ended chamber forming said intake chamber and is mounted on the stem in sliding but sealed relation thereto.

Abstract: ADSORBENT FRACTIONATOR WITH AUTOMATIC TEMPERATURE-SENSING CYCLE CONTROL AND PROCESS               ABSTRACT OF THE DISCLOSURE:     A method and apparatus are provided for adsorbing water vapor or other first gas from a mixture thereof with a second gas to reduce the water vapor or first gas concentration in the mixture to below a permissible maximum concentration, in which the advance of the leading edge of the adsorption front in a sorbent bed is detected by sensing the advance of the temperature front that precedes the adsorption front, and this advance is detected by sensing the temperature of the sorbent bed sufficiently far from the end of the bed to prevent the temperature front from leaving the bed, using a temperature sampling probe; when the temperature front reaches this point, the adsorption front is still a distance away, since it follows the temperature front, and the adsorption cycle is discontinued, and the bed regenerated; the regeneration cycle can similarly be controlled independently, to be terminated when regeneration is complete, as detected by advance of the temperature front in the opposite direction.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for making particulate substantially water-insoluble magnesium phosphate product and method of use of the product for removing ammonia from aqueous solutions.          The particulate magnesium phosphate product acts as a remarkably effective scavenger wherein under equilibrium con-ditions only about six (6) grams of the product are required to bind the ammonia (more exactly, ammonium ions) liberated from one (1) gram of the urea, a result far superior to tra-ditional zirconium phosphate (ZP) prior art materials which under ideal conditions require about 17 to 20 grams of ZP per gram of urea.  The particulate magnesium phosphate product can also be used for the removal of ammonium ions either produced by enzymatic or non-enzymatic hydrolysis of urea or proteins or amino acids or available as NH4+ from its native source.  The magnesium phosphate product is made by forming a slurry of water and magnesium hydroxide in the presence of a phosphate ion-containing buffer having a pH of about 6.5 to about 8.5 and reacting the slurry with H3PO4.

Abstract: ABSTRACT OF THE DISCLOSURE               The time history of a molten metal casting charge being introduced into a mold cavity is recorded by an electrically operated recording means including a plurality of electrical circuits, each of which produces a timing signal upon being completed or closed and is connected to an electrical timing lead having an electrically bare, free end adapted to be located in the mold cavity.  The free ends of the timing leads are positioned at predetermined locations of interest in the mold cavity and the molten metal serves as a common ground for completing the electrical circuits in the recording means.  The timing cycle is started in response to the molten metal contacting the electrically bare, free end of an electrical trigger lead located near the inlet of the mold cavity and electrically connected to the recording means.  Time signals, indicative of the elapsed time between the starting time and the time the molten metal reaches each of the predetermined locations in the mold cavity, are produced in response to the molten metal contacting the free ends of the timing leads.

Abstract: Abstract A corrugator for receiving plastic from an extruder and continuously molding corrugated plastic tile therefrom.  The corrugator has a plurality of mold assemblies which are continuously driven to roll about an endless track-way on the corrugator frame, a portion of which defines a molding section.  Each mold assembly includes a pair of mold blocks mounted to pivotally open and close.  As the mold assemblies enter the molding section, the mold blocks thereof pivotally close and come into abutting relationship with the closed mold blocks of preceeding mold assemblies to cooperatively form a corrugated molding tunnel.  Extruded plastic is received by the molding tunnel which moves with and molds the corrugated tile.  At the end of the molding section the mold blocks pivot away from and release the tile.  To augment the formation the tile the mold blocks are cooled.  Additionally a vacuum is induced between the extruded plastic and the wall of the molding tunnel to assure the mating thereof.
