Abstract: Ridged with a plate mounted on a door jamb is an inward extension, on the free end of which is pivoted a latch which swings between door-blocking and door-unblocking positions. The latch is releasably retained in door-blocking position by a flat strip having one end pivoted to the latch and a free end engageable between the door and the door jamb. The latch also has an intermediate position which permits the door to be cracked open.

Abstract: The process comprises the step of determining the coordinates of each wrapper to be cut out, allocating a cut-out tool to each wrapper, displacing each of the tools individually to bring them all into similar relative starting positions, and simultaneously displacing the tools along identical paths. Each tool is fixed to a lever pivotally mounted on a rotary shaft perpendicular to respective wrappers, a connecting rod being pivotally mounted on the shaft and the lever.

Abstract: A device for measuring the visibility, or diffusion coefficient, of atmosre air, including a light source for directing light onto a volume of air and a receiver capable of measuring the flow of light diffused by the volume of air. The source is surrounded by ambient air and furnishes a beam diverging in essentially all directions except within at least one dark cone. A receiver opening is directed toward the source, but is located in the dark cone so as to receive only diffused light. The apparatus is for use in meteorological installations, notably in airports.

Abstract: A carding apparatus is illustrated wherein trash removal means is provided utilizing a carding flat means together with a first plate carried for vertical adjustment relative to the flat means for varying the setting between the plate and a clothed carding cylinder. A second plate has means for setting a surface thereof in close proximity to the surface of the clothed cylinder. A relatively wide setting is provided for the first plate and a slot is formed by the first and second plates which will be self-expelling of trash, short fibers and the like by reason of such wide setting of the first plate followed by the close setting of the second plate acting as an air barrier upon the opened fibers carded by the carding flat means. A suction plenum provides a system of removing a large part of the already expelled trash so as to greatly improve the carding operation while minimizing loss of desirable longer fibers.

Abstract: A method for desalination of sea water using a main electrochemical generr which has an anode compartment through which the water to be desalinated is fed and which causes formation in the solution of chlorates and perchlorates, removal of the latter being effected by a potassium salt such as potassium bicarbonate. The insoluble matters are separated from the solution, while the residual salts dissolved therein are oxidized at the anode of secondary electrochemical generator(s), under the form of persalts apt to be precipitated and removed by settling or filtration. The insoluble matters obtained at the various stages of this treatment can be decomposed by heating or electrolysis or under the action of a strong acid such as hydrochloric acid. The power consumed during desalination may be wholly or partly supplied by the above mentioned main electrochemical generator and secondary electrochemical generators.This method may be used to provide fresh water for agricultural, industrial or domestic purposes.

Abstract: A self contained freezing device for forming a plug of ice within a pipe section. A refrigeration unit supplies refrigerant to a cradle like freezer unit within which the section of pipe to be frozen is held in spaced relation to the inner face of the freezer. The space between the underside of the pipe and the inner face of the freezer is filled with water, for example by spraying. As the water freezes, in contact with the cradle like freezer unit, it covers the outer surface of the pipe section with an ice jacket. Alternatively, a bag of freezable jel may be substituted for the water spray and placed over the inside face of the freezer; and then the pipe section is placed within the fold of the bag. In the case of either alternative, the refrigerant is maintained inside the freezer, and out of contact with the pipe.

Abstract: The present invention relates to a method for producing gaseous or liquid fuels or hydrocarbons from solid mineral sources and, more particularly, to a process for producing solid compounds, hereinafter designated fuel precursors, capable of releasing or generating flammable gases or liquids by chemical and/or physical conversion phenomena and to the process and methods to accomplish said fuel generation. The fuel precursors consist primarily of carbides formed from two or more metallic elements combined with carbon. The precursors additionally may contain minor amounts of free metal, unreacted carbon or other impurities.

Abstract: An electric receptacle for trade size outlet boxes having a ground fault circuit interrupting machanism incorporated therein. A receptacle housing includes contact jaws seated therein to receive the plug of a conductor leading to a load, electronic components to detect a ground fault and grounded neutral condition on the load side of the receptacle, plus a coil and trip mechanism to open the receptacle circuit on occurrence of a ground fault or grounded neutral condition.

Abstract: A method and apparatus for manufacturing bars made of an alloy by unidireonal solidification. The mold is moved relative to a hot source and a cold source disposed below the hot source. The relative positions of the two sources as well as their efficiency and the displacement speed of the mold are set so that there is established within the alloy contained in the mold a planar solidification front with a high thermal gradient at the level of the front, and so that there is produced an orientation of the structure of the alloy which is perpendicular to the solidification front. During the whole duration of the solidification, the mold is fed with alloy powder having the required nominal composition at the rate corresponding to the quantity of alloy solidified per unit of time.

Abstract: A railroad track relaying train comprises, in addition to the cars for transporting the ballast screening machines and a car equipped with power-wrenches for fixing the tie-screws, a sequence of working cars including a tie- and rail-removing car, a ballast clearing car, and a tie and rail laying car, these cars being interconnected by means of coupling frames supported by caterpillar trucks adapted to keep the working cars on the selected path. The tie and rail removing car comprises an elevator capable of lifting and rotating at least one tie or a track span around ballast conveyors, in order to deposit at least one tie or track span upon a transport element. The train is capable of performing all of the operations necessary for removing the old track, excavating and screening the old ballast, and laying the new track on the screened ballast, without stopping its forward motion when removing the old track.

Abstract: An interlock device for a pair of vaporizers of an anesthesia machine. Each vaporizer includes a rotary dial for establishing the vapor concentration provided. The interlock device insures that one vaporizer is closed whenever the other is open and comprises a pair of reciprocable pins and a cooperating pivotable lever. Each pin is arranged to be extended into a cam recess in the vaporizer dial by the pivoting action of the lever. Rotation of one dial automatically causes the pin located therein to move out of the cam recess and into contact with the lever. This action pivots the lever and causes it to contact the other pin to extend the other pin into the recess in the associated vaporizer dial, thereby locking the dial closed.

Abstract: An economic route to transport fuels from low grade feedstocks containing organic polycyclic components and mineral and/or metallic components comprises separating the feedstock into (a) a residue containing fuel values and substantially all of the mineral and metallic components and (b) a liquid hydrocarbon fraction; hydrogenating the liquid hydrocarbon fraction; providing hydrogen for the hydrogenation by steam reforming methane-containing gas recovered from the hydrogenated material; and providing the heat for the steam reforming by immersing the reformer reactor tubes in a fluidized bed heated by combustion of residue from the separation step. If the fluidized bed is pressurized, the process can be made substantially self-contained with all the heat and power requirements for steam generation and feedstock compression for hydrogenation and steam reforming being recovered from the flue gas.
