Abstract: RESISTIVE LOOP ANGULAR FILTER            ABSTRACT OF THE INVENTION      An angular filter (30, 50) for electromagnetic radiation is formed of a set of elements supported on a dielectric substrate.  The elements are rods (100) or loops (50) which are electrically conducting and include resistance for dissipating energy of the radiation.  Each rod (100) is formed as a linear element parallel to the axis (300) of propagation of the radiation.  Each loop element (50) is formed as a closed loop in a plane normal to an axis (40) of propagation of the radiation.  This minimizes interaction with a transverse magnetic field of the radiation at zero angle of incidence to the filter, the interaction and consequent attenuation increasing with increasing angle of incidence.  Thereby, spurious sidelobes of a radiation pattern associated with a radar or other antenna can be reduced by the filter in favor of the main lobe along the antenna axis.  The loop elements (50) may also be formed by a set of members (38) spaced apart to introduce capacitance for resonating with inherent inductance of the members, thereby to enhance the filter attenuation.

Abstract: ABSTRACT OF THE DISCLOSURE   A KITE STRING SLIDER         A toy accessory for a kite comprises a slider intended to ride up the string of an airborne kite.   The slider comprises a frame (3,  4, 5,  6) intended to be suspended from the kite string by pig-tail eyelets (7,  41).   The front eyelet (41) forms the trigger of a latch mechanism including a cranked wire element having an intermediate limb (43) slidable longitudinally in holes (15,  8) in the frame, and a sear (46) slidable in hole (9) in the frame.   The sear (46) latches a lever (27) in the position shown, in which it holds a pair of pivoted wings (1) in their operative spread position via ties (47), and, via a spring (26), holds a pivoted clip (23) in its uppermost position to trap a folded toy parachute between the frame member (5) and the clip (23). The slider is propelled up the kite string by wind pressure acting on the wings, until the front eyelet (41) strikes a stop on the kite string.   This causes the wire element, and therefore the sear (46), to slide back, the lever (27) is released to pivot anti-clockwise, permitting the wings (1) to pivot forward to a folded position under the effect of an elastic band (40), and releasing the spring (26), allowing the clip (23) to hinge down and release the parachute.   With the wings folded, the slider slides back down the kite string.   The slider is then reloaded, and the latch mechanism reset, ready for a further ascent.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for applying self-adhering elastic strips to a flexible base material includes adhering a tensioned first strip of the self-adhering elastic material to a flex-ible base material by sandwiching a lessor untensioned strip of the self-adhering elastic material between the ten-sioned strip and the base material.  Tensioning the first strip in order to impart a sufficiently high degree of elas-ticization to the base material reduces the inherent strength of adhesion of the strip to the base material.          Accordingly, the lessor untensioned intermediate strip in-sures good adhesion strength of the composite of the two (or more) strips to the base material.  The resulting article comprises one having elasticized portions formed by adher-ence of the tensioned composite strip of self-adhering elas-tic material thereto.

Abstract: ABSTRACT            Portable, gas-fired heaters are known to consist of an outer casing, a gas burner, a gas supply pipe, a gas-flow valve, and they have the convective draft of combustion air enter the heater along the lower sides or through a perforated bottom.          In this invention greater compactness, portability, reliability and safety are achieved by a combination of a central-ly-located flue and a rounded, closed bottom to the heater. The flue is so disposed as to create a reverse-draft inlet at the top of the heater, thus cooling the outer walls of the heater casing.          A rounded lid permits emergency extinguishing of the flame, and dust free storage for the burner. A retractable wire grill and a heat diffuser serve to keep the temperature of the heater's external top surface below a desirable maximum value during heater operation.

Abstract: METHOD OF EDGE SMOOTHING FOR A COMPUTER IMAGE GENERATION SYSTEM ABSTRACT A method for computer image generation simulated visual scenes for applications such as flight training. The processing to generate the image takes place in three sequential stages: Controller, Geometry Processor, and Display Processor. At any point in time, the stages are processing data for three consecutive scenes. Each scene is comprised or a plurality of faces. Processing prior to the Display Processor accomplishes clipping and perspective transformation of faces. The Display Processor then generates the scene with pipeline processing accomplishing four major tasks: span detection or windowing, span sequencing, mask processing, and color processing. The improved realism of the computer generated image includes application of area-times-color smoothing, using fractional face areas to improve scene quality and reduce quantizing artifacts.
