Abstract: An autoregulating, electrically shielded heater employs a laminated structure having two magnetic alloy permeable materials of widely differing Curie point temperatures and preferably of differing resistivities. A constant current supply is connected across the laminate such that current flows in the laminae along parallel paths. Due to skin effect, the current is confined to a thin region of a first lamina which is located between the other lamina and the electrical return path. This first lamina has the lower Curie temperature and preferably the higher resistivity of the two laminae to produce heating proportional to I.sup.2 R.sub.1. When the Curie temperature of the first lamina is approached, the current spreads into the other lamina which may have a lower resistivity and higher Curie temperature and heating is obtained by I.sup.2 R.sub.2 where I.sup.2 is a constant due to the constant current source and preferably R.sub.2 <R.sub.1.

Abstract: A flexible autoregulating heater with a latching mechanism to form the strap that may be applied about work to be heated, the strap holding the work during the heating and subsequent cooling cycle. The strap may then be removed or permitted to remain in place to provide a resulting binding force about the finished product. A band strapping tool is modified to not only draw the strap tight but apply electric current to activate the heater.

Abstract: A production control system is provided, especially for use in a works environment, in which a microsequencer controlled by a Z80 microcomputer board (MUXC) performs continuous high-speed scanning of a multiplicity of operator input devices (OIDs) located at the work stations of individual human operatives. The microsequencer is essentially a single-level pipelined microprocessor communicating with the OIDs via channels and sub-channels, each OID being connected to a respective sub-channel by a single twisted-pair cable. The cable lines are maintained at 24 volts d.c. to supply power to the OID, and the OID, which has a card-reader for reading bar code on cards or tickets passed through it by the operative, transmits data to its sub-channel, and hence the microsequencer, over the same cable by shorting out the two cable lines for short and long pulse periods.

Abstract: In an I-F substitution loop having a summing junction for receiving both an I-F signal and a substitution signal, an amplification loop is connected in parallel with the substitution loop for amplifying and bandpass filtering the signal at the summing junction, and feeding back to the summing junction the processed summing junction signal, for reducing the phase noise at the summing junction.

Abstract: Provided herein is an in-line, non-invasive device and method for calculation of consistency of a non-Newtonian fluid flowing in a laminar manner through a non-rotating conduit where the consistency is calculated directly from a power-law model equation employing as independent variables pressure head loss over a specific distance and the bulk velocity of the fluid.

Abstract: A launcher is provided for a remotely piloted aircraft that has a launch ramp mounted on a transport vehicle and a carriage which is accelerated up the ramp carrying the aircraft to be launched. The carriage is hauled along the ramp by a cable leading to and wound around a winch drum which is driven by a flywheel through an electromagnetic slipping clutch, the flywheel being first run up to speed by an electric motor coupled to it by a torque limiting coupling. A hold-back device retains the carriage at the lower end of the ramp until the cable tension has built up to a predetermined value, and a brake system decelerates and arrests the carriage at the upper end as the aircraft leaves. On a short transport vehicle, the length of the ramp can be reduced for travel either by making it telescopic or by arranging it to fold about a hinge.

Abstract: An aircraft ejector release unit (E.R.U.) is provided in which ejection is accomplished by a pair of angularly moving ejection arms carrying pivotal thrust pads and both mechanically actuated by a common gas-operated piston-and-cylinder unit. The gas piston operates a crank that turns a central lever assembly coupled by actuating rods to rotate triangular cranks disposed near opposite ends of the E.R.U. Control links pivotally mounted at their upper ends on the E.R.U. body are pivotally connected at their lower ends to the ends of the ejection arms, and when the triangular cranks are rotated the ejection arms are extended by unfolding of the ejection arms and the control links, there being a pivotal connection between each crank and the respective ejection arm at a location intermediate the ends of the arm. Before the ejection arms extend, initial movement of the central lever assembly unlocks store suspension hooks of the self-releasing, sear type.

Abstract: An airborne missile launcher is provided which is of modular construction to carry a variety of different missiles. A main body section has top attachment points, whereby it is carried by an aircraft, and sub-rail hangers at its underside to receive alternative missile-carrying sub-rails each of which sub-rails has one or more longitudinal tracks for carrying one or more types of missile. The sub-rail may be mounted in telescopically sliding relationship with the main body section. To complete the launcher body, forward and aft body sections are attached to the main body section, each of the forward and aft body sections being selected from a number of different such sections to suit different types of missile. For certain missile types, the forward and aft sections may be simply a plastics fairing; for certain other missile types, the forward and aft section may house a missile umbilical retraction mechanism and other operative means.

Abstract: A simple, highly flexible, virtually massless, temperature autoregulating heater primarily useful for soldering has an energizing circuit that may be integral with or separate from the heater element, which element has a ferromagnetic material energized via the circuit from a constant current source whereby regulation occurs about the Curie temperature of the magnetic material. The energizing circuit may be in the form of a printed circuit conductor formed on a thin layer of Kaptan or like high temperature insulating material having the heater formed on the reverse side thereof or having a sticky substance thereon so that the energizing circuit may be temporarily adhered to the heater and removed after use. Alternatively, the energizing circuit may be formed directly on Nomex paper or the like; a quite thin paper with a sticky backing.

Abstract: Method and apparatus are disclosed for producing and sustaining a very intense pinch effect in a ralativistic electron beam by applying a continually accelerating strong electric field along the entire length of the beam. A special anode collects electrons that stray from the beam and conducts them along a conducting wall of the anode. The potential drop due to the flow of these electrons in the anode wall produces a strong electric field along the beam. The clusters of heavy ions in the beam impact a target made of lead, for example, and produces various varieties of sub-nuclear products including mesons, neutrons, neutrinos, and hadrons. Electrons liberated from atoms appear adjacent the cathode along with ions also resulting from the liberation. These electrons are accelerated toward the target leaving behind the positive ions which produce a positive potential trough.
