Title: Improvements in the processing of geological and geophysical data
IPC: G02B27/46
Filed: 1965-04-23
Abstract: 1,112,121. Geophysical prospecting. CONDUCTRON CORPORATION. 23 April, 1965 [27 April, 1964; 24 June, 1964], No. 17159/65. Heading H4D. [Also in Division G2] Geophysical data is processed by recording the data on a transparency and optically converting the transparency to its Fourier transform for analysis or further processing. For removing undesired data from a seismic section comprising a plurality of parallel, variable-area or variable-density traces and corrected for static and normal moveout errors, the section is recorded as a transparency 36 which is illuminated by collimated light from a heliumneon laser 20, 21, 22. The Fourier transform of the transparency (which acts as a diffraction grating) is formed at 44 by lenses 38 and 42 and comprises points of light whose distance from the optic axis is dependent on the spatial frequency of seismic " events " in the traces of the transparency. Alignments of " events " on the traces give alignments of points of light in the transform, the latter alignments appearing at 90 degrees (measured round the optic axis) to the former. An adjustable filter mask 46 blocks undesired frequency components or undesired alignments, e.g. those from multiple reflections of seismic energy, which are oriented differently from desired primary alignments. Lens 42 provides a magnification of the Fourier image to make positioning of mask 46 less critical. The filtered transform is subjected to a further Fourier transformation by a lens 48 and the reconstituted image of the processed transparency is recorded at 54. The reconstituted image at 54 may be observed to determine the optimum adjustment of mask 46 or to provide a basis for designing field recording procedures and other data processing operations for optimum removal of undesired data. Instead of masking off Fourier transform components, the filter 46 may alter the relative phasing of different components by some fraction of a light wavelength. Field recording procedures for obtaining the seismic section are described.

Abstract: 405,274. Optical sound-reproducing apparatus ; electrical musical instruments. GUIBIANSKY, J., 29, Granville Road, Stroud Green, London. June 18, 1932, No. 17300. [Classes 40 (ii) and 88 (ii).] Relates to apparatus for reproducing sound from a set of records of musical notes, of the kind in which reproduction is effected photoelectrically under keyboard control, the records being arranged as parallel tracks on a stationary film which is scanned by travelling light beams. Apparatus made in accordance with the invention is characterized by the following main features in combination : (i) the keys actuate obturators consisting entirely of non- transparent material, (2) the light is reflected on to the records by a manifold mirror unit or is controlled by a slotted shutter, and (3) the note records are arranged in a single row or in staggered formation on a long narrow film. The apparatus shown in Fig. 1 comprises a lamp L, an optical system U, a rotary multiple mirror M, and a narrow film F on which the series of note records is arranged as a row of parallel transverse tracks, the film being fixed adjacent to a photoelectric cell C. A set of light apertures 0, one for each record, is formed in the housing H, a corresponding number of piston obturators P being slidable across the apertures O. The pistons P are operable from a distant keyboard (not shown), by means such as Bowden wire connections K. In a modification, Fig. 2, the photoelectric cell C is surrounded by a cylindrical rotary shutter X, having a number of parallel longitudinal slits. Light from a lamp L is transmitted through any selected record on the film F, and through the moving slits, when the corresponding obturator P is moved so as to open the appropriate aperture O. The apertures O may be provided in a corrugated plate, in the channels formed by which plate the obturators are slidably arranged. The operating keys may be arranged in oblique parallel rows, or constructed like a pianoforte keyboard. A set of three parallel photoelectric cells may be provided. Further, instead of a single electric lamp common to all the records, each note may have its own small lamp, connected directly to a key-operated contact.

Title: Improvements in methods for the production of composite images
IPC: G03B15/08
Filed: 1937-06-23
Abstract: 502,890. Composite photographs. PLANSKOY, L. June 23, 1937, Nos. 17461 and 17462. Void. Convention dates, June 25, 1936 and Dec. 14, 1936. [Class 98 (ii)] The two images of a composite photograph have backgrounds of greater and lesser density respectively and are produced by preparing a background which is lighted by either polarized or infra-red light, lighting the subject with ordinary visible light and taking two photographs, the one without and the other with interposed means which absorb the polarized or infra-red light. When polarized light is used, the background is strongly lighted either by reflection or by transparence, and the second view is taken by placing an analyser in the path of the photographing light rays. When infra-red light is used, e.g. of wavelength greater than 7000 A.U. the first view is taken on a film sensitive to infra red and through a filter which transmits wavelengths greater than 7000 A.U. The background is one that does not reflect visible light, and may include a pigment such as chloramine black. The second view is taken through a filter which transmits only light below 7000 A.U. With the two views obtained, masks may be produced for making composite black and white or colour photographs. The method may be used to compose several scenes on a single background.

Title: Monostable multivibrator circuits
IPC: H01L21/331
Filed: 1975-04-28
Abstract: 1505118 Monostable semi-conductor circuit SONY CORP 28 April 1975 [7 May 1974] 17550/75 Heading H3T A monostable circuit comprises a semi-conductor device Q (Fig. 3, not shown) having three regions of alternating conductivity type fitted with electrodes, a fourth electrode being separated from the first region by an insulating layer; a trigger signal is applied to the second electrode and a capacitor is connected between the third and fourth electrodes, bias being provided independently to the fourth and second electrodes. The first region may contain a sub-region of higher impurity concentration within the minority carrier diffusion distance of the junction between first and second regions. The first, second and third regions act respectively as emitter, base and collector of a bipolar transistor; while the fourth behaves as an insulated gate (as in an IGFET) controlling h FE  the common-emitter current amplification factor of the transistor: the h FE  characteristic against gateemitter voltage V GE  has the form (Fig. 7) of a valley symmetrical about some negative bias (-V 1 ) matching the setting of bias line (-B 2 ) to which the gate is connected via resistor 15. In the absence of a signal the transistor is kept non-conducting by the drop due to base current across resistor 11, holding the output of high positive potential V H . A positivegoing pulse (Fig. 8A) applied via capacitor 13 to the base causes conduction from collector to emitter, effectively earthing output terminal t 2  (Fig. 8B) and the corresponding terminal of capacitor 14. The gate (Fig. 8C) follows, moving the working point of V GE  further negative and increasing the amplification factor h FE , thus accentuating conduction. The capacitor discharges through resistor 15, allowing the gate potential to rise until h FE  falls as the valley is re-entered; conduction then stops sharply and the potential of the output terminal t 2  returns rapidly to its original level V H  as at 16. The conductivity type of the device may be reversed.
