Abstract: The field rate of a video input signal is doubled by storing each field in a memory (40, 202, 204) and recovering each stored field twice so as to repeat each field and thus reduce flicker. To ensure that even fields overlay even fields, odd fields overlay odd fields and that all pairs of even and odd fields are interlaced, a timing unit (70) provides a double field rate read control signal (2V) to the memory having a waveform that repeats ona two-field basis and supplies a double field rate vertical synchronizing signal (2Vʹ) to a display (60) having a waveform that repeats on a four-field basis. Thus not all fields are of the same number of lines, and appropriate patterns of control signal (2V) field rate and vertical synchronising signal (2Vʹ) field rate ensure correct overlay and interlace. Registration of images is enhanced further by means of a vertical scan generator having a constant retrace time, a fixed retrace level and employing DC coupling thereby avoiding raster shift which otherwise could occur as a result of the use of non-equidistant vertical synchronizing pulses.

Abstract: A one-way valve is arranged with an accumulator in a manner wherein the discharging of the accumulator is restricted. During upshifting, the stroking of a band brake servo in a release direction is induced before the charging stroke of the accumulator and the appropriate timing of the engagement of a high clutch (H/C) and the disengagement of a band brake (B/B) is induced. During downshifting, the pressure which is prevailing in the conduiting interconnecting the two friction elements is allowed to drop rapidly during the initial stage of the shift due to the provision of the one-way orifice (110) and allows the torque transmission capacity of the clutch to quickly reduce while inducing the stroking of the band brake servo in an engaging direction before the discharge stroke of the accumulator.

IPC: G01V1/36
Filed: 1988-01-15
Abstract: The level of signal noise caused by fluid flow at a pressure transducer, such as a hydrophone or geophone (1), is determined by measuring the electric field (Vx, Vy) induced when the fluid flows through a magnetic field. The electric field, which is proportional to flow rate, is measured by electrodes (4a - 4d) positioned about the transducer. The pressure due to the flow is derived from the flow rate voltage by a digital filter (8) which may be adaptive, to allow for varying flow conditions, or which may employ a predetermined electric field/flow noise relation. This flow noise is then subtracted from the received signal, the resultant signal then being substantially noise-free.

Abstract: A digital video probe system has a digital data probe for attachment to a data test point and a digital clock probe for attachment to a clock test point of a device under test. A clock signal from the clock test point is variably phase shifted by changing the duty cycle of the clock signal to produce a variable clock signal for processing digital data from the data test point. The processed digital data is converted to an analog video signal and displayed on an appropriate analog monitor. By varying horizontal and vertical sync inputs to the analog monitor the displayed signal may be moved about the display to assure that all of the processed digital data is displayed.

Abstract: An optical transducer system for producing an optical output signal representative of the rotational speed of a rotary member, particularly a shaft of a gas turbine engine, comprises a conventional inductive speed probe positioned adjacent the shaft to sense the passing of the teeth of a toothed wheel secured to and rotatable with the shaft. The inductive sensor thus produces an AC output signal whose frequency is proportional to the rotational speed of the shaft, and this signal is used to excite electrostatically vibration of a cantilever beam micromachined in silicon. The vibrating beam is arranged in an optical path defined by one or more optical fibres, such that its vibrations modulate light directed along the optical path at a frequency which is again proportional to the rotational speed of the shaft.

Abstract: An electric motor armature current control circuit includes an electric motor (16) with an armature in series with a protection device (13) comprising a pair of polymer PTC elements (17,18) connected in electrical series with the motor armature windings and in electrical parallel and thermal contact with each other. The first polymer PTC element (17), a temperature compensating element, has a very low cold resistance and a trip temperature higher than the maximum expected ambient temperature to which it is to be exposed in motor operation and generates heat in motor operation to trip to a much higher resistance and become self-regulating at that trip temperature. The second polymer PTC element (18) is maintained at least at the trip temperature of the first through thermal contact and has a lower resistance at that temperature than the cold resistance of the first. Its trip temperature is higher so as to be reached only with excessive armature current. Due to the temperature compensation element, the protection device limits excessive armature winding current after a period of time independent of ambient temperature.

Abstract: A method and apparatus adapted to measure a three-­dimensional curved surface shape quantitatively with high speed. A pattern of interference fringes on a surface of an object to be measured is picked up so that while moving a reference plane (or the object to be measured) in the direction of an optical axis, the resulting video signal is processed to form a composite image in which a value of each of picture elements is represented by a position of the reference plane (or a position of the object to be measured) at an instant that one of positions on the object surface corresponding to that picture element in the image attains a maximum brightness. Then, a three-dimensional curved surface shape of the object to be measured is measured on the basis of the composite image.

Abstract: In rotationally driven rolling heads (4), rolls (5) are rotatably mounted in such a way that they revolve in a planetary manner when the rolling heads (4) rotate. As a result, the rolls (5) roll instantaneously on the outer surface of the rotating (7) work piece (W) fed (II) along its axis (A). A reduction in the diameter of the work piece (W) is thereby achieved, the material being displaced mainly in the longitudinal direction. The work piece (W) is moved along its axis (A) in the feed direction (II) at an axial feed rate of at least 3 mm per work-piece revolution, and in the case of hollow work pieces preferably at at least 5 mm per work-piece revolution. Here, the difficulties otherwise occurring in the case of certain materials can be avoided, it being possible to also increase the production rate along with the quality. The method can be applied to materials and work pieces which were hitherto considered to be very difficult to work. In the case of hollow work pieces which undergo inner profiling on a mandrel, the work piece thus fed at a high axial feed rate is preferably also rolled during the reverse feed. The reverse feed should at most be the same size as the feed but within its order of magnitude. During the return rolling, the inner profile of the hollow internally profiled work pieces can be corrected and the outer surface smoothed. The method can be applied to materials and workpieces which were hitherto very difficult to work.
