Abstract: In a phased array antenna the phase of the signal applied to each antenna element (5) is controlled by a phase lock loop which is locked to the frequency of a reference oscillator (6) but whose phase is offset from it alternatively by introducing a DC offset to an integrator (7c) within the phase lock loop or by presenting a digital code to a counter circuit.

Abstract: An acousto-optic tunable filter to provide a minimum of resolution degradation when operated in a wavelength scan mode. A second face of the acousto-optic crystal opposite the first face on which the acoustic transducer is mounted is disposed so as to be non-parallel to the first face. As a result, acoustic waves launched into the acousto-optic crystal are reflected by the non-parallel second face resulting in the production of minimal diffraction of the light passing through the crystal by reflected acoustic waves.

Abstract: A lock (18), particularly suitable for locking a top packer against upward movement relative to a lower packer in a well bore, includes a radially movable latch member (102) slidably mounted in a radial cavity (62) defined in an inner mandrel (22) which is movable relative to an outer member (36,32) to which the top packer is connected in the exemplary use. Spring biasing elements (144,146) are used to retain the latch member in a disengaged position until, from within (58) the mandrel, an actuating pressure is exerted radially outwardly on the latch member with a force greater than both the inward biasing force of the spring biasing elements and a radially inwardly acting force exerted by a hydro­static pressure existing externally of the outer member but communicated internally thereof. When this occurs, gripping teeth (110) on the latch member interlock with an engagement surface (100) on the interior of the outer member.

Abstract: The stop element (13) consists essentially of the bearing block (31), the clamping member (33), the clamping screw (35) and the supporting screw (37) for the clamping member (33). Arranged in the flange (40, 41) are four fitting bores (25) arranged at a matrix distance (R or 2R), two of which serve in each case to receive fitting pins and two of which serve to receive screws (17). Situated at a distance (h) from the bottom face (39) is the bearing surface (43), arranged parallel to this bottom face (39), for the work piece. For the lateral stopping of the work piece, the stop face (44), arranged perpendicularly to the bottom face (39), is provided. This stop face (44) lies in the same plane as the median line (45) of two bores (25). As a result, after mounting the stop element (13) on the hole-matrix board (11), the stop face (44) also extends parallel to a line (45') which represents a line of the hole matrix. <IMAGE>

Abstract: A transducer for measuring a parameter of a fluid, such as density or viscosity, comprises two generally parallel tines extending from a common yoke, forming a tuning fork adapted to be immersed in the fluid. The tines are excited to vibrate resonantly and in anti-phase by one or more piezo-electric exciting elements, which are housed in one or more cavities within the tines or the yoke. The vibrations are sensed by one or more similarly-housed piezo-electric sensing elements. The tines are shaped to enhance their sensitivity to the parameter to be measured: for example they are provided with re-entrant surfaces to enhance density sensitivity, or elongated in the direction in which they vibrate to enhance viscosity sensitivity.

Abstract: An optical sensor comprises a polychromatic light source (3), a detector (4), and first and second polarisers (7) (8) disposed in the light path between the source and the detector. The polarisation axis of the first polariser (7) is substantially orthogonal to that of the second (8), and there is a modulating element (6) of birefringent material disposed therebetween. The modulating element is disposed such that a change in the parameter to be measured alters the optical path length of the polychromatic light through the modulating element, thereby changing the colour of the light incident on the detector (4). The detector comprises first and second photo-responsive elements (9) (10), the responsivity with respect to wavelength of the first element (9) being different from that of the second (10). Signals from the photo-responsive elements are fed to a microprocessor (13) which calculates the colour of the light incident on the detector as represented by two or more parameters on the Chromaticity (CIE) Diagram, and interprets this colour in terms of the parameter to be measured.

Abstract: A preferred embodiment of the graded filter (1) has two bearings (9) and (10) for the axes of rotation (7) and (8) of the filter discs (3) and (4). The axes of rotation (7) and (8) are driven by a motor (5) via a belt transmission. The belt transmission consists of a double belt pulley (29) on the drive shaft (28) of the motor (5) and two toothed belts (35) and (36), which each wrap around a toothed belt pulley (23) and (24), respectively, on the axes of rotation (7) and (8), respectively. By contrast with the known gear transmission, the belt transmission is less expensive, more practical, low in wear and lighter in weight. The plane of the intersecting axes of rotation (7) and (8) is slightly inclined with respect to the direction of the optical axis (6) of the graded filter (1). The result of twisting the axes of rotation (7) and (8) is that the toothed belts (35) and (36) bear snugly against the contact surfaces (25) and (26), respectively, of the toothed belt pulleys (23) and (24), respectively so that the latter and the toothed belts (35) and (36), respectively, are uniformly loaded, which increases their service life and guarantees a constant transfer of force. <IMAGE>

Abstract: A proton-exchange method of forming optical waveguides within a lithium-based optical substrate is disclosed which utilizes sulfuric acid as the proton source. The substrate is masked to expose the areas desired to be transformed into waveguiding regions and immersed in a heated sulfuric acid bath for a period of time sufficient to provide the exchange between the protons in the acid and the lithium in the substrate. The presence of the protons in the substrate results in increasing the extraordinary refractive index Δn e  in the unmasked area so that optical guiding may be accomplished. Upon removal of the substrate from the sulfuric acid bath, the substrate must be annealed so as to drive the protons to a depth sufficient to provide effective guiding.
