Title: Measurement apparatus
IPC: G01B11/00
Filed: 1974-03-15
Abstract: 1504691 Measuring relative displacement NATIONAL RESEARCH DEVELOPMENT CORP 14 March 1975 [15 March 1974 14 Oct 1974] 11598/74 and 44522/74 Heading G1A An apparatus for measuring displacement of a first member relative to a second member in a manner corresponding to motion with one degree of freedom in a given plane, the apparatus comprising a grating 7 mounted in a fixed position relative to said first member and having lines which are spatially periodic in the sense of said motion, means 1 for illuminating the grating, the illuminating means comprising means mounted in a fixed position relative to said second member and defining an optical object e.g. a grating 3 which is spatially periodic in said sense and is substantially uniformly spaced from the grating 7, whereby the grating 7 will produce an image of said object which is spatially periodic in said sense and is substantially uniformly spaced from the grating 7 and which will move in said manner relative to said second member when relative movement in said manner occurs between said first and second members, and photo-detector means 6 for receiving light from the illuminating means which has been imaged by the grating 7, the photo-detector means comprising a structure which may include at least part of the grating 3 which structure is spatially periodic in said sense and is mounted in a fixed position relative to said second member, and the arrangement being such that said structure will interact with said image to cause a cyclic variation in the output of the photo-detector means 6 when relative movement in said manner occurs between said first and second members. As shown the optical object and structure are the same grating 3. The two gratings may have substantially the same spatial periodicities and lie in substantially parallel planes. The illuminating means includes a light source 1 which illuminates the grating 3 diffusely. Arrays of photo-emissive elements and photo-sensitive elements may be mounted one array at each end of the grating 3, Fig.5 (not shown), although an array of photo-sensitive elements may be interlaced with the photo-emissive array. When using interference fringes four photo-detector elements are placed to receive, resulting from relative movement between the two members, cyclical variations which differ in sequence with movements of 90  degrees. When four photo-detectors are used alternate ones are coupled in pairs, and their differenced and squared signals are applied to J-K flip flops, outputs from which are fed to a counter, Fig.6 (not shown).

Title: Improvements in or relating to devices for stabilizing a high frequency regenerativeamplifier
IPC: H03C3/30
Filed: 1939-03-17
Abstract: 530,871. Valve amplifying and generating circuits. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. March 17, 1939, No. 11656/40. Convention date, April 14, 1938. Divided out of 530,785. [Class 40 (v)] [Also in Group XXXV] An ultra high frequency regenerative amplifier is stabilized in frequency and amplitude by automatic means adapted to allow rapid changes while maintaining the average substantially constant. The amplifier is of the type comprising a plurality of spaced fields, at least one of which is confined within a hollow resonator of the type described in Specification 517,264, and has a feedback connection. The Fig. shows an electron emitter 1 with an accelerating grid 3 arranged to project an electron beam through resonant hollow bodies 5 ... 8 containing pairs of spaced grids 15 ... 18 which produce velocity grouping. At the output a plate 32 may be negatively biased so that only electrons of more than average velocity strike it, or the plate 32 may be positively biased so that only electrons of less than average velocity fail to strike it. The electrons impinging on the plate produce voltage across resistor 53 while the electrons passing through the aperture in the plate 32 may be observed on fluorescent screen 34. Biased rods 33 or a magnet 35 may be used to concentrate the beam striking the screen 34. The discharge space is sealed to maintain a vacuum while the hollow bodies are adjustably tunable by dipole 36 or coil 37 or by condensers 43, 44 associated with a coil 38 or dipole 39. Gang tuning may be effected by a member having vanes 47 between which standing waves are produced through apertures 40, the member being adjustable through rod 48. Reaction is effected by coupling between bodies 7, 8 through loops.57, 58. The bunching of the electrons at the grids may be effected as described in Specification 523,712, alternatively the beam may be deflected as described in Specification 529,771. As shown the signal voltage across resistor 53 is arranged to vary the bias of grid 56 to provide automatic control. The resonant hollow bodies 74, 77 coupled by the loops 88, 89 and having associated therewith the electron source 71 comprise an oscillator to which the output of the resonant hollow body 8 is coupled by loops 85, 87. In this way a phase modulated wave may be detected at plate 79 and applied through resistance 95 to a direct current amplifier 96. The output is coupled to the tube 75 through which the electron beam passes and thus changes the frequency of the oscillator. Specifications 530,869 and 531,067 also are referred to.

Title: Improvements in or relating to methods and devices for detecting faults
IPC: G01N33/34
Filed: 1965-03-19
Abstract: 1,085,621. Fault detector. P. LIPPKE. March 19, 1965 [March 21, 1964], No. 11669/65, Heading GIN. Faults in a sheet or sheets of a fibrous material, such as paper, cause variations in a capacitor formed of two plates 3, 4, Fig. 1, between which the sheets move, the capacitor 3, 4 being connected to an inductance 2, thus forming a resonant circuit which is tuned to a frequency which is  different from that of an oscillator 1 connected to the inductance 2, changes in this frequency difference being used to control at 8 a sorting device. The voltage at a point 5 on the inductance 2 varies with the changes in frequency difference, and is rectified and supplied to the control device 8 via a capacitor 6 and amplifier 7. Any permissible gradual changes in sheet thickness cause a slowly changing signal at 5 which is delayed at 19, 20 and applied to an amplifier 16 which compares a signal derived by rectifying the oscillator 1 output, with the delayed measurement signal, a trimming capacitor, 18, being adjusted by a motor 17 until the resonant frequencies again differ by the required amount. This arrangement also renders the system independent of temperature and supply voltage variations. The trimmer may be in the oscillator circuit. In one embodiment Fig. 3 (not shown) two measuring capacitors, movable across the width of the sheet, have respective resonant circuits, the outputs of which are compared, and a common oscillator (not shown). In a further embodiment Fig. 4 (not shown), a plurality of capacitors, having one plate common to all, is arranged across the width of the sheet and these have their respective resonant circuits connected to "ring" fashion so that any two adjacent capacitors have their values compared, and the two outer capacitors have their values compared. The capacitors are mounted on a support member which is protected from vibrations of the associated machinery, for example by resilient blocks (56, Figs. 3 and 48, Fig. 2, not shown) or resilient lamina, (52, 53, Fig. 2, not shown). The separation of the measuring capacitor plates 3, 4, may be adjusted.

Title: Improvements in and in the manufacture of inductance coils for use in wireless telegraphy and telephony
IPC: H01F17/02
Filed: 1923-05-04
Abstract: 220,047. Akister, F. May 4, 1923. Inductances.-A coil is made by first winding a cylindrical insulating casing provided with end on an insulating strip 1, Fig. 1, mounted as an incomplete cylinder and securing them by shellac or the like, and then winding the strip into a clock-spring spiral as shown in Fig. 2. The parts of the wire 7, 8, 9 between the ends of the strip become twisted as shown. These parts may be separated by insulating strips to diminish their self-capacity. The twisted portions should be arranged circumferentially in the finished coil to prevent distortion of the field. In a modification, Fig. 6, the insulating strip 1 is wound as a helix on a split cylindrical mandrel 14 of resilient material and the wire is wound on the strip from end to end and led back along the gap in the mandrel for successive windings. After securing the wire to the strip the mandrel is removed and the strip deformed into a clock-spring spiral. In this form no twisting is effected. The coil so formed comprises a number of similar coaxial conical spirals spaced apart with re-entrant series connections. The insulating strip may be removed after the winding has taken its final form. The coil may be tapped at the connecting loops or elsewhere. The coil may be enclosed in walls and with terminals, plug contacts or trunnions.
