Title: Variable camber wing
IPC: B64C3/48
Filed: 1980-09-26
Abstract: A variable camber wing comprises a movable portion 2 pivotally coupled to a fixed portion 1 by a tilt arm 20. Tilting movement of tilt arm 20 about a fixed tilt axis 18 is effected by a powered hinge 19. The movable portion is pivotally mounted on the tilt arm 20 about pivot axis 21. Control means coupled between fixed portion 1 and movable portion 2 effect pivotal movement of the movable portion simultaneously with tilting movement thereof. The control means comprises a pair of assemblies, each comprising a bracket 9 or 10 attached to the fixed portion 1, a pivotted sleeve 14 mounted on the bracket and which slidably carries a control arm 11 or 12, secured to the movable portion 2. Flexible upper skin panel 22 of the movable portion 2 slides at 23 under fixed portion upper skin 4. Rubber strip 25 connects lower skins 5, 8 of portions 1, 2. Movable portion 2 may be a leading edge or trailing edge flap, and may include a blowing slit for boundary layer control over upper surface. <IMAGE>

Title: Ultrasonic testing
IPC: H03K4/50
Filed: 1980-10-21
Abstract: An ultrasonic testing instrument includes an ultrasonic generator, a testing head, an echo receiver and amplifier and an oscilloscopic display of the echo signals reflected from faults or inhomogeneites of the test object. In order to avoid the necessity for repeated re-calibrations of the instrument, characteristic data are entered via a keyboard 17 and corresponding digital values are stored in memory. A microprocesor 114 then sends out sequences of ultrasonic pulses of regularly varying rise/fall times and correlates the measured times with a table that permits matching the closest value to the selected data. During actual operation, the traversing time of the CRT deflection sawtooth wave is compared digitally with a calculated time and a suitable correction signal is applied to a current source 115 which modifies the charging current of timing capacitors so as to match the correct sawtooth traversing time. Additional circuitry provides for on- screen display of the position and dimensions of a detection window, textual information and other data. <IMAGE>

Title: Improvements in and relating to circuit testing apparatus
Inventor: SMITH ANTHONY JOHN
IPC: G01R31/319
Filed: 1982-03-02
Abstract: In the automatic testing of electrical or electronic circuits via pins (1, 2...30) test signals may be applied to points in e.g. a logic circuit to be tested, the signals preferably being applied for such short periods of time as not to damage components in the circuitry. High speed switches (HSS), preferably electronic, are individually enabled so as to pre-select particular pins (1, 2 . . .30), and a pulsed voltage source (270) then momentarily energises these pins. Output signals are read by energising one of three relay coils (168, 170, 172) each of which connects all the pins of a respective group (e.g. pins 1 to 10) to output lines (71, 72...80). One of these lines is then selected by a switch (150). Control means (154) controls and switches (HSS) in accordance either with pre-stored information or with information specially generated (if no pre-stored information is located for the particular circuit to be tested). In the latter case, the specially generated information is stored so as to be available when that particular circuit is next tested. <IMAGE>

Filed: 1982-05-05
Abstract: A high accuracy dimensional measuring and checking machine comprises a bridge structure not shown carrying a measuring or checking device and movably arranged on parallel guideways (10, 12). In one embodiment level sensors (16, 18) are respectively operatively associated with the guideways (10, 12) and are operatively interconnected whereby one of the sensors (18) can produce a differential output signal indicative of any relative misalignment. The signal is applied to a servojack at A associated with the same guideway (12) whereby to reposition the guideway (12) to correct the misalignment. In alternative embodiments each guideway may be individually levelled by comparing each sensor with an external reference, or one may be so levelled which then becomes a reference for the other, or a sensor may be mounted on the bridge to control the guideways or to level the bridge directly. The alignment is automatically checked and corrected at intervals. <IMAGE>

Title: Alkali metal cell seal
Inventor: BINDIN PETER JOHN
IPC: H01M50/179
Filed: 1982-06-10
Abstract: In a sodium sulphur cell having, within a metal housing, a ceramic electrolyte tube (10) separating the liquid alkali metal from the cathodic reactant, a current collector (14) extends into the region inside the electrolyte tube (10) and is electrically insulated from the electrolyte by an insulating element (11).

Title: Boot seal
Inventor: WOODY ALBERT L
IPC: F16J3/02
Filed: 1981-01-26
Abstract: An elastomeric seal apparatus (16) having an inner annular terminating portion (36) which is attachable to a first (12) member, an outer annular terminating portion (38) which is attachable to a second (14) member, and an annular convoluted flexible portion (40) which is disposed between the inner (36) and outer (38) terminating portions and has an inner (46) and an outer (48) margin which are respectively joined thereto. The thickness of the convoluted flexible portion (40) decreases from the relatively thicker inner margin (46) to the relatively thinner outer margin (48) in proportion to a radial distance (H) extending from the inner margin (46) to the flexible portion (40). A concentrically inner convolution (42) and a concentrically outer convolution (44) constitute the flexible portion (40) and have a relatively small (R<u1>u) and a relatively large (R<u2>u) radius of curvature. When the inner (36) and outer (38) terminating portions are relatively reciprocated with the first (12) and second (14) members about a longitudinal seal axis (16a), the tapered, convoluted structure of seal apparatus (16) exhibits extended life as a result of substantially equalizing the maximum uniform strains induced therein.

Patent GB-2123228-A (GB)
Title: Apparatus for measuring a delay imposed on pulses
Inventor: DUNN PETER LEONARD
IPC: G01R29/02
Filed: 1982-07-01
Abstract: Previously methods which employ electronic devices for measuring small delays have in many cases proved to be unsatisfactory, since delays in the responses of the devices are appreciable when compared with the short time intervals to be measured. Sensor and reference pulses are sent along sensor and reference optical fibres 3 and 4 respectively to a photodiode 5 which detects them. The pulses are then applied to a bistable 8 together with additional pulses from a pulse generator 7 having a lower frequency. The output of the bistable 8 is applied to a low pass filter 10. Because of the additional pulses, which switch the mean amplitude of the output of the bistable 8 between two values, errors due to the difference between fall and rise times of the bistable 8 are eliminated. The voltage produced is representative of the delay and is fed back to control the frequency of an oscillator which produces the sensor and reference pulses so as to position the sensor pulses midway between reference pulses. <IMAGE>

Title: Facially animated manikin
Inventor: GREER THOMAS J
IPC: G09F19/08
Filed: 1983-01-22
Abstract: A facially animated manikin head (100) for simulating human facial expressions includes a rigid substrate (24) in the shape of the head, which is partially covered with elongated, pressurized fluid-filled tubes (10,16) serving as deformable motor elements. The tubes (10,16) are either covered by or embedded in a deformable layer (262) which is positioned on the head to simulate a face, and has its outer surface textured and tinted to simulate facial skin. When various groups of the tubes (10, 16) are deformed by varying the fluid pressure within them, various facial expressions are simulated by the resulting distortion of the contiguous skin layer (262). Alternatively, the deformable motor elements may comprise helical wire coils or a grid of parallel wires embedded in the simulated skin, the passage of a direct current through selected coils or pairs of wires causing them to deform by moving together axially or at right angles to their length respectively, thus distorting the skin layer. <IMAGE>
