    Abstract: A phase matched thin film waveguide supportive of electromagnetic wave energy having angular frequencies is disclosed. In one embodiment, the waveguide includes a sequence of strips each of length A/2 in the direction of wave energy propagation and spaced apart from one another a distance A/2, A 2 pi / Delta Beta , where Delta Beta is the phase constant difference required to satisfy the relationship Beta 1 + Beta 2 Beta 3 + Delta Beta , Beta 1, Beta 2 and Beta 3 being, to a first order of approximation, the phase constants respectively of the wave energy. In other embodiments, the spaces between the strips are filled with materials whose nonlinear optical coefficient is either zero or different from the nonlinear optical coefficient of the spaced apart strips. The filling material''s index of refraction is substantially equal to that of the spaced apart strips.

    Abstract: A filter for removing particulate impurities from a fluid comprising a hollow, generally cylindrical housing having axial fluid channels along the inner surface and open opposite ends forming an inlet and an outlet for the filter. A plurality of annular, generally disc-shaped filter elements are tightly stacked within the housing. Outer edges of the filter elements bear on the inner surface of the housing and combine to form the axial fluid channels while inner edges of the filter elements combine to form a hollow inner core communicating with one of the open ends of the housing. Each filter element includes a plurality of radial channels between the axial channels and the hollow inner core and each channel includes means defining a lowvelocity pocket for trapping particulate impurities in a fluid flowing therealong. One end of the hollow inner core is blocked such that the path for fluid flowing between the inlet and outlet is through the axial and radial channels and the hollow inner core.

    Abstract: Apparatus for welding a continuous insulated wire to numerous terminal pins of a circuit board, including a solid central electrode which presses the wire against the terminal pin to rupture the insulation and then weld the wire to the pin. A concentric second electrode has a pair of openings on diametrically opposite sides of the center electrode for closely guiding the wire across the face of the central electrode, one of the openings being a hole that completely surrounds the wire and the opposite opening being a slot which is open at its bottom end. After each point of the wire is welded to a terminal pin, the electrodes are lifted and then initially moved parallel to the axis of the wire portion that is welded to the previous terminal pin, and only then is the direction of electrode movement changed to carry it to the next terminal pin.

    Abstract: An electromagnetic transducer head is provided which exhibits a wide band recording response characteristic, and which comprises a plurality of separate magnetic head structures operating over different, overlapping frequency bands, and formed into an integral assembly. Each separate head structure of the assembly includes a magnetic core, and each core is provided with a gap. The cores are positioned adjacent one another so that the gaps are aligned to define a common gap, and the recording medium is drawn across the common gap. The common gap is tapered, with the gap width of each aligned gap section being different from its adjacent section. Separate windings are wound about the cores, each having different numbers of turns so as to cover overlapping frequency ranges.

    Abstract: A magnetic recording and magneto-optic playback system is disclosed wherein thermomagnetic recording is employed. A transparent isotropic film is heated along a continuous path by a focused laser beam. As each successive area of the path is heated locally to the vicinity of its Curie point in the presence of an applied magnetic field, a magneto-optic density is established proportional to the magnetic field and fixed in place as the area cools once the laser beam moves on to an adjacent area. The magnetic field is varied by an input signal so that the magnetooptic density established in a given area of the film is proportional to the amplitude of the input signal being applied. To play back the recorded data, the intensity of the laser beam is reduced to avoid reaching the vicinity of the Curie point of the film as it is scanned by the laser beam in the same manner as for recording. A Faraday effect analyzer and photo detector are employed as a transducer for producing an output signal.
