摘要： A method of testing a curved surface of a body, which can be used on bodies having only partial arcs available for testing and apparatus for performing the method comprising drawing a sensor over the surface of the body between two end points at which the relative angular orientation of the sensor and the body are known, and calculating from the information signals from the sensor, and from signals representing the relative angular orientation of the body and the sensor during the traverse, the parameters of a best fit limacon from which data indicating the eccentricity between the centre of the partial arc on the body with respect to the centre of relative rotation can be obtained and also a signal can be generated representing a reference figure against which surface variations of the body over the partial arc can be compared.

摘要： Misregistration in a multi-scanning television system such as a colour television camera as a result of variation of an optical parameter such as a zoom lens setting is compensated automatically by varying the size of one or more of the scanned areas in the pickup tubes of the system, for example by modifying the deflection coil current, using signals derived from variations of lens setting parameters for example potentiometrically.

摘要： A lighting control apparatus for stage lighting and the like in which lighting values are stored and handled entirely by digital techniques, the apparatus being based on a general-purpose digital computer. The invention also provides a novel method of controlling crossfades from one lighting state to another which is economical in its demands on data handling capacity, since it operates by defining the required changes as a given number of increments thus permitting further control to be by means of addition and subtraction only. A novel clock circuit for use in this incremental cross-fading is described.

摘要： An electronic circuit which gives an output corresponding to a first input so long as that output is within limits set by a second input. When the output goes beyond these limits, a diode connected thereto is forward biased to establish a high loop gain feedback path holding the output constant.

摘要： AN IMAGE TRANSMITTING DEVICE IS MADE BY BRINGING TOGETHER SEVERAL SEPARATE OPTICAL FIBERS TO FORM A FLAT TAPE. THE TAPE IS CUT INTO SEPARATE LEGTHS AFTER THE FIBRES HAVE BEEN CAUSED TO ADHERE TO ONE ANOTHER. THE LENGTHS ARE STACKED AND THE ENDS AT LEAST OF THE STACKED TAPES BONDED TOGETHER. APPARATUS FOR MAKING THE IMAGE TRANSMITTING DEVICE INCORPORATES A DEVICE FOR BRINGING INDIVIDUAL FIBRES TOGETHER TO FORM A TAPE, MEANS FOR CUTTING THE TAPE INTO LENGTHS AND MEANS SUCH AS A CHANNEL IN WHICH THE CUT LENGTHS OF TAPE ARE STACKED.

摘要： A zoom lens having an improved zooming range and comprising a convergent first member which for a given object distance remains stationary during the zooming relative movements, an axially movable divergent second member behind the first member having equivalent focal length fb lying numerically between 4 and 8 times the minimum value of the ratio of the equivalent focal length of the complete objective to the f-number of the objective in the range of variation, an axially movable divergent third member behind the second member having equivalent focal length fC lying numerically between 5 and 10 times the minimum value of such ratio, a stationary convergent fourth member behind the third member, a zoom control element, and means whereby operation of the zoom control element causes the zooming relative movements to be effected, wherein the total axial movement of the second member in the range of variation lies numerically between 1.5fB and 2.5fB and the total axial movement of the third member in the range lies numerically between 0.25fC and 0.5fC, the minimum axial separation between the second and third members occurring when the equivalent focal length of the object is greater than half its maximum value in the range of variation, the movable divergent second member consisting of a divergent simple meniscus component with its surfaces convex to the front and a divergent compound component behind such simple component, and the movable divergent third member consisting of a doublet component having its front surface concave to the front with radius of curvature lying numerically between 0.5fC and 1.0fC.
