Abstract: ABSTRACT OF THE DISCLOSURE           A portable microfiche reader that has a lens and mirror assembly in a housing, pivotally mounted to swing between two positions.  When the assembly is swung into one stable position, the mirror and lens system is stored in a position where it interposes no added thickness to the microfiche reader case.  When the assembly is swung into another stable position, the lens and mirror are accurately positioned with respect to a microfiche in a reading position. This way, the reader case may be designed to have only the minimum thickness required by the screen, microfiche carriage, and light source.  Automatic means are provided to open the fiche-holding glass flats when the carrier is moved forward.

Abstract: AGITATOR FOR AN AXIAL FLOW CYLINDER                   ABSTRACT OF THE DISCLOSURE         A cylinder cage of an axial flow combine has radial openings about its circumference permitting threshed material to leave the cage as the threshing cylinder is rotated.  An agitator mechanism is provided to dislodge threshed material tending to accumulate on the top side of the cylinder cage.  Once dislodged, the threshed material will fall to a distribution auger which in turn delivers the threshed material to accelerator rolls disposed beneath the threshing cylinder and cylinder cage.  The agitator includes a plurality of curved ribs or fingers spaced axially along and adjacent the outer periphery of the cylinder cage.  The agitator fingers are rigidly secured to a backbone member, which in turn is supported on the main frame of the combine by a pair of parallel links.  An oscillating device is con-nected to one of the parallel links causing it to swing horizontally back and forth which in turn effects oscillat-ing movement of the agitator in the axial direction of the cylinder cage.

Abstract: TITLE: FIRE RETARDANT INSULATION            Abstract of The Disclosure A flame retardant thermal insulation material comprising a dry, shredded cellulosic material, such as newsprint, which is coated with a dry phosphorous-containing, flame retardant composition.  The composition is one which is capable of decomposing near the ignition temperature of the shredded paper, which is between 120 degrees and Celsius and 250 degrees Celsius and preferably includes a plurality of compounds which decompose at different temperatures spaced within this range to provide the stagewise release of combustion inhibiting agents.  The composition can be a single compound such as calcium phosphate but preferably is a combination of similar compounds such as (NH4)2HPO4, CaH4(PO4)2, CaHPO4 and triple super phosphate.  Further, the phosphorous composition is preferably combined with urea.  Elemental sulfur powder may be included with any of the previous compositions as a smoke retardant.  The paper and flame retardant composition are maintained in the dry solid state during processing, application and use.  The insulation is manufactured by shredding the paper and thoroughly mixing it with the finely ground, powdered flame retardant composition to intimately coat the paper with the flame retardant powder.  The shredded, coated paper may be bagged for later use as poured or blown in insulation or it may be filled into elongated plastic envelopes to form insulative batting.  The filled envelopes may be provided with longitudinal flanges and have a size and shape suitable for stapling between the wall studs of a structure.  Air may be evacuated from the filled envelopes to facilitate transportation, storage and installation as insulating batting during construction of structures such as new homes.          After installation the evacuated envelopes are punctured to permit reentry of air and the expansion of the batting.

Abstract: ABSTRACT OF THE DISCLOSURE   An improvement is provided in a process for preparing polyolefins wherein olefins are polymerized or copolymerized in the presence of a catalyst.  The improvement resides in using, as the catalyst, a solid com-ponent and an organometallic compound. The solid component is either (A) a substance obtained by the copulverization of (1) a reaction product resulting from a heat reaction of magnesium oxide and aluminum trichloride, at an A1/Mg atomic  ratio of from 0.3 to 5 at a temperature of from 150° to 600°C., and (2) a titanium compound and/or a vanadium compound, or (B)a substance obtained by copulverization of (1) a reaction product resul-ting from a heat reaction of magnesium oxide and aluminum trichloride at an Al/Mg atomic ratio of from 0.3 to 5 at a temperature of from 150° to 600°C., (2) at least one of a titanium compound and a vanadium compound, and (3) an organic halide. The polyolefins obtained by this process have a wide molecular weight distribution. In other words, they have a large flow parameter. When such polyolefin is extruded, the molding obtained has superior surface conditions.

Abstract: ABSTRACT OF THE DISCLOSURE          Radiation sensitive switching elements which undergo thermal decomposition to interrupt a circuit path when activated are operatively associated with a plurality of high-voltage type flash lamps.  The lamps use a primer material which short-circuits after flashing to provide an electrical path across the lamps.  The combined actions of the open-circuiting switching elements and the short-circuiting lamps enable the flash lamps to be flashed sequentially in a high-voltage activated multiple flash lamp array.  The thermal decomposition of the radiation sensitive switching elements produces self-destruction of the switch elements per se.  The thermal decomposition can be accom-panied by further destruction of the underlying substrate on which the switch elements have been deposited.  The switching elements are deposited on a circuit board member and electrically connected in the sequential lamp firing circuitry at circuit board locations adjacent to the associated flash lamps.  The desired thermal action accompanying switch operation is enhanced in a preferred embodiment by constructing the circuit board from an organic polymer material which melts or decomposes and locating the switching elements at circuit locations wherein the underlying substrate has a thickness less than the substrate thickness elsewhere in order to produce holes in the circuit board member itself as the means of permanently interrupting the electrical path.

Abstract: GAS TURBINE ENGINE AND MEANS FOR COOLING SAME                         Abstract The turbine blades of a gas turbine engine are individually cooled through the internal circulation of a fluid coolant by the thermosiphon principle. Each turbine blade has associated therewith a closed-loop coolant passageway which is rotatable with the turbine rotor disk and which, in one embodiment, passes through a heat exchanger borne by, and rotatable with, a rotatable lubrication duct. The blade internal coolant is placed in heat exchange relationship with engine lubrication oil within the heat exchanger. The heated lubrication oil is then placed in heat exchange relationship with the engine fuel and the fuel thus heated is burned in the combustor, thereby returning at least a portion of the heat removed from the turbine blades to the engine power cycle. The cooling system is designed for simplified blade removal and replacement and the entire turbine can be removed from the engine as a sealed unit. A secondary cooling system is provided as a backup in the unlikely event that cooling effectiveness of one or more of the blade coolant loop passageways is lost.
