Abstract: A folding multi-tool comprising first and second generally channel-shaped handles each having first and second ends, each generally channel-shaped handle having an open side and an at least partly closed side opposite the open side, the at least partly closed sides comprising plier-receiving openings. The folding multi-tool also includes pliers including first and second plier halves pivotally and adjustably mounted to each other, with the plier halves being pivotally mounted between flanges at the first ends of the handles. Control straps extend between the flanges for limiting the maximum pivotal movement of the plier halves and for frictionally resisting pivotal movement of the plier halves. The folding multi-tool is foldable between a closed, compact configuration and an opened, extended configuration for operating the pliers and in the opened, extended configuration the open sides of the handles face each other.

Abstract: A process and apparatus for gasifying high moisture content carbonaceous material by introducing a solid first carbonaceous material (1) into at least one pressurized drier vessel (2), the first carbonaceous material having a moisture content above about 30 wt % wet basis. The moisture content of the first carbonaceous material is reduced by passing a hot flue gas having a low oxygen content through the pressurized drier vessels. Then the dried first carbonaceous material is transferred from the drier vessels to a pressurized carbonizer vessel (10). The dried material is partially gasified in the carbonizer vessel to produce a high temperature fuel gas (18) and a solid residual material (16). The solid residual material is transferred to a pressurized combustion chamber (4) to produce the low oxygen content flue gas for the pressurized drier vessels.

Abstract: The present invention discloses an aircraft control system having simultaneously controllable rear aileron/elevators and a retractable body flap for longitudinal stabilization. The aileron/elevators are airfoils comprising the complete horizontal tail plane. Control arms for the rear aileron/elevators are capable of pivotal movement about the longitudinal axis of the aircraft while the aileron/elevators are secured to the control arms by axles pivotal about the lateral axis of the airfoil, for directional control. With two degrees of rotational movement, the aileron/elevators are capable of maneuvering the aircraft in all three axes, providing a much simpler mechanism than the conventional control surfaces. Added safety is accomplished by removing lateral control from the wings. Weight savings and reduced drag also result from eliminating the vertical stabilizer and rudder and consolidating the controls for both ailerons and elevators of conventional aircraft.

Abstract: An apparatus and a method for the analysis of the surface of a specimen by the techniques of electron energy spectroscopy and secondary ion time-of-flight mass spectrometry. The apparatus provides a substantially conventional electron energy analyzer, typically having hemispherical electrodes. The energy analyzer is used as an ion deflector and in conjunction with a linear drift region and a pulsed primary ion beam gun provides a time-of-flight mass spectrometer having at least first-order time focusing properties. By using the energy analyzer in both techniques a combined instrument is provided at much lower cost than prior combined instruments which comprise different analyzers for the two techniques.

Abstract: A charged particle analyzer which irradiates a specimen and analyzes charged particles emitted therefrom, for example a photo electron spectrometer, having a flood-source which emits charged particles to neutralize the charge which develops on a specimen. The analyzer is provided with electrostatic and magnetic lenses which may be used separately or in combination. The flood source is provided within the lens column of the analyzer and is arranged such that when the electrostatic lens is in use, the charged particles emitted by the flood source pass around the outside of the objective electrostatic lens element, whereas when the magnetic lens is in use, or when both lenses are in use, they pass through that element.

Abstract: Apparatus used for local simulation of a metallic pair of 22 Gauge conductors, such as comprising a telephone line, 6.5 miles in length at 70 degrees Fahrenheit consisting of a resistance network. This apparatus is useful for fault identification of telephone line amplifiers, allowing for local activation when used in conjunction with milliampere test meters, in lieu of a technician's required travel to a minimum of 6 miles to perform the same task. This apparatus is useful in that it allows for function testing of typical line amplifiers at the source of the metallic pair.

Abstract: The invention relates to ranging drum shearers having cutting drums driven by electric motors mounted on the respective ranging arms. A coal sizer is pivotably mounted on a shroud of the motor and is maintained at a constant disposition regardless of the position of the ranging arm. The coal sizer is maintained at a constant disposition through a control arm pivotally mounted to the pivot axis of the ranging arm and having a keyway containing a key on the axis of the coal sizer. The key and keyway provide for longitudinal movement of the coal sizer relative to the shearer body whereby on the pivotal movement of the ranging arm, the control arm remains stationary and the distance between the key and the axis of the shroud is maintained by the longitudinal adjustment of the coal sizer in the keyway.

Abstract: A process and apparatus for removing solid propellant from a rocket motor case. Water is heated to a temperature of at least about 150.degree. Fahrenheit, pressurized to a pressure within the range of about 600 to 1200 psi, focused into a jet, and directed while moving relative to the propellant surface at an angle relative to the propellant surface which is in the range of about 15 to 45 degrees from a stand-off distance of up to about 20 inches.

Abstract: A method and apparatus for hydraulically macerating and recovering soluble component from a solid material such as waste solid propellant that is semihard. The solid material is fed into a perforated enclosure where it is held until it is macerated such that it can pass through perforations in the enclosure. While held in the enclosure, the solid material is agitated and exposed to jets of liquid solvent under a pressure which is equal to at least about 1000 psig to thereby macerate the solid material and force it through the perforations and to dissolve soluble component such as ammonium perchlorate from solid propellant. In one embodiment, the propellant residue is conveyed to a residue discharge end of the apparatus by a sloping helical conveyor. The helical conveyor provides individual contact stages for counter-current extraction and washing of ammonium perchlorate from the residue with recycled solvent.

Abstract: In accordance with the invention, the stemming of blast holes, i.e. the covering (with peviously removed earth materials) of explosive charges placed in receiving boreholes drilled downwardly from generally horizontal surfaces in open-pit mines, involves the proper manipulation of a special vehicle relative to earth material cuttings that collect concentrically about the mouth of such a borehole during the drilling operaton. The vehicle carries a combination of earth-moving blades that can be raised and lowered as a unit and that comprises a transverse pusher blade mounted on one end of the vehicle and a pair of elongate auxiliary blades pivotaly mounted on and in mutually spaced relationship transversely of the pusher blade as arms which can be swung toward and away from each other. The auxiliary blades have respective tip portions turned toward each other, and are preferably arranged to stop short of meeting when swung together so as to accommodate the blast cord between such tip portions.
