Abstract: A pair of conductive strips 9, 10 in a waveguide, for example, defining a fin-line transmission line insert have a switching element such as a PIN diode 11 connected to them to reflect or pass r.f. energy in the fin-line section. The switching element 11 forms part of a filter circuit, for example, in conjunction with inductances 12, 13, the characteristic impedance of which is matched to that of the gap. When the PIN diode is forward biased, the strips 9, 10 are in effect short circuited and the r.f. energy is reflected. When the diode is reverse biased, the r.f. energy passes without reflections. Due to the matching of the impedances this obtains over a broad bandwidth.

Abstract: A process is disclosed for the preparation of a tabular grain silver bromoiodide emulsion in which silver bromoiodide laminae are formed on the major faces of the tabular grains. The sensitivity of the emulsion as a function of pressure applied is rendered more nearly constant by forming the silver bromoiodide laminae on the major faces of the tabular grains. The silver bromoiodide laminae are formed on the major faces of the tabular grains with an iodide content higher than that of the host emulsion, and thereafter, within the pAg and temperature boundaries defined by Curve A in Figure 1, bromide is deposited as a silver salt with the addition of iodide being limited or absent.

Abstract: This invention relates to a technique for forming filament windings which are designed to enable filament (52) to be paid out at a high rate used particularly for guided missile systems using a filament as a data link. Numerous prior art techniques exist which have disadvantages such as difficulty in winding, poor coil stability, and high drag associated with paying out of the filaments. Additionally, some of the prior art techniques do not result in a densely packed coil, thus requiring larger size spools and compromising the packaging efficiency of the overall system. In accordance with this invention, a "deep nested" filament coil winding (80, 94, 102) is provided. By providing a pitch distance of approximately the filament diameter times the square root of 3, and advancing the coils in two equal steps as the turns wrap around the coil spool, a highly densely packed coil is provided which can be wound against a single flange (84, 104) or a pair of separated flanges (84, 86). The winding features excellent mechanical stability and can be wound using conventional winding machines.

Abstract: A process of forming a diffraction grating on a semiconductor substrate (21). The diffraction grating has a phase inversion area (26) at the center thereof. The process has the steps of coating a photoresist film (22) (which has a characteristic that light-sensitivity thereof reverses depending on an exposure time period) on the semiconductor substrate (21), dividing the photoresist film (22) by a first exposure into an unexposed area (24) and an exposed area (23) in which the light-sensitivity thereof is reversed, exposing and developing the photoresist film (22) which has been divided into the unexposed (24) and exposed (23) areas by a second exposure, thereby to form a diffraction grating pattern (25) that includes the phase inversion area (26), transferring the diffraction grating pattern (25) formed on the photoresist film (22) to the substrate (21), and removing the photoresist film (22) from the substrate (21). The diffraction grating having the phase inversion area (26) can be formed by using the same, one resist (the second resist). The separation film, which was required in a conventional technique between the positive and negative resists, can be obviated.

Abstract: A hydrocyclone (10) establishes a first vortex (15) of fluent material at one end (e.g. in a top portion 4), and a second vortex at the other end (e.g. in a bottom portion 24). The first vortex is established within a porous surface of revolution (18) to which gas or other fluid is supplied, passing through the porous surface into the first vortex. The second vortex is established by a conical end section (24) extending outwardly from (e.g. below) the porous surface, and with an axial (e.g. bottom 23) discharge for fluent material. Some fluent material -- for example having heavy particles -- is removed tangentially from the conical end section at a portion (35) near the porous surface of revolution. A conical shroud (25) having a circumferential periphery is mounted by a number of spaced legs (28) connected between the shroud and the conical bottom section so that fluent material may pass (thru 32) between the circumferential periphery of the shroud and the porous surface of revolution. An axial gas passage (27) is provided in the shroud to allow gas to escape from the second vortex into the first vortex, and ultimately out the first end (e.g. top) of the hydrocyclone (Figure 1).

Abstract: The present invention provides a fluid transferring apparatus which achieves a second-dimensional flow of fluid with high efficiency and at low noise by imitating a Weis-Fogh mechanism with use of a simple mechanism. In the fluid transferring apparatus, a wing assembly X comprising a predetermined number of plate-like wings 4 is provided in a transverse direction of a flow passage 2. The wing assembly X is supported by a link 5 of a crank mechanism Y1 which consists of a crank 6 rotated by a motor, a slider 8 slidable in a direction orthogonal to a direction of a flow in a flow passage 2 , the link 5 coupling the crank 6 with the slider 8, so that rotational motion of the crank 6 is transmitted to the slider 8 as a reciprocal movement. While an angle of attack of each wing 4 is changed by the oscillating action of the link 5, each wing 4 is moved in a transverse direction of the flow passage 2 as the link 5 is reciprocated, thereby achieving transfer of fluid.
