Title: Improvements in or relating to liquid level indicator
Inventor: DYE DEAN C
IPC: G01F23/26
Filed: 1955-12-08
Abstract: 792,484. Capacitor-type level gauges. ARO EQUIPMENT CORPORATION. Dec. 8, 1955, No. 35243/55. Class 37. A'capacitor used to indicate the level of liquid, particularly liquid that must be maintained at high-pressure or low temperature, e.g. a liquefied gas, in a container, has three parallel plates similar in shape to the vertical cross-section of the container, to prevent inaccuracy of indicator readings due to distortion of capacitor plates or to non-linearity of the cross-sectional shape of the container. As shown, the capacitor is mounted within an ellipsoidal container which is constructed in two halves and is enclosed in an evacuated shell. Projections 30 on the periphery of the outer plates 16, 20 are welded to the interior of one half of the container before the second half is welded to the first half. The central plate 18 is connected to an oscillator circuit including a recording instrument by a conductor 37 introduced into the container, preferably through a plug 31 (Fig. 3), which is screwed into the bottom of the container. The plates are insulated from one another by dielectric spacer elements 22, 24 (Fig. 4) or similar devices.

Title: Mapping subsurface structures in the earth
IPC: G01V1/28
Filed: 1971-07-27
Abstract: 1359719 Seismic exploration UNITED GEOPHYSICAL CORP 27 July 1971 [27 July 1970] 35319/71 Heading H4D A digital image of a subsurface region of the earth is built up in memory cells of a computer by deriving digital representations of the amplitude of seismic wavelets from seismic record traces; allocating the cells to respective elemental parts of the image; and storing replicas of said amplitude representations in cells corresponding to isochronic image points (i.e. those image points defining the locus of various possible subsurface points which, for the same seismic source-receiver geometry as was used in obtaining the wavelet record, would return a seismic wave to the receiver with the two-way travel time associated with that wavelet) whereby the replicas accumulate algebraically in the cells and establish the image. Field procedure.-The records to be processed may be obtained by a roll-along or split spread (common reflection point) continuous profiling method, with linear or areal source-receiver arrays and automatic gain control of receiver amplifiers, and may be in analogue or multiplexed digital form. Twenty or more records preferably are made per 1000 ft. along a survey line. A marine survey method is described. Signal processing.-Stacking and normal movement corrections prior to the above storage procedure are optional. The records are reproduced as, or converted to, digital signals for input to the computer. For each source-receiver geometry and seismic travel time the isochronic image points are computed and the replicas are transferred to the memory cells corresponding to those points. Algebraic accumulation of data in the cells enhances the signal-to-noise ratio. For imaging a twodimensional vertical profile of the earth as shown in Fig. 13, the memory cells are notionally allocated to a two-dimensional array of image points C(IJ) and the isochronic points for a source-receiver combination S, R form sets which lie on respective curves DL1, DL2 &c. respectively associated with the various travel times. For example assuming a constant seismic velocity, these curves will be ellipses with S and R as foci. Replicas of successive portions of a wavelet may be stored in a subset of cells, e.g. as on a vertical line VL. In practice the image point array may be three dimensional. Visual images in two or three dimensions are displayed by reproducing the cumulative data stored in the cells. The display may be a plot, e.g. photographic, of a selected sectional plane through the image space, or a three-dimensional display in which subsurface structures are represented by semi-transparent objects.

Abstract: 451,479. Milling ; copying-mechanism. DECKEL, F., 7, Waakirchnerstrasse, Munich, Germany. Dec. 20, 1935, No. 35342. Convention date, Jan. 19. [Class 83 (iii)] [See also Groups XX and XXIV] In an engraving or copying milling machine wherein the tracer and cutter are carried by a pantograph, a handle is connected with the tracer through a transmission gear so that it moves through greater distances than the tracer in order to reduce the effort of the operator in moving the pantograph. In one form the pantograph is pivoted at 3, Fig. 1, on a shaft 2 rotatable in fixed bearings 1 and carries a cutter 6 and a tracer 8. The handle 10 is connected by links 9 to extensions 7b of the pantograph links 7a so that its distance h from the pivot 3 is greater than the distance t of the tracer 8. The scale of reproduction may be varied by adjusting the lengths of the links 4b, 7a, and three dimensional work may be performed by oscillating the pantograph about the axis 2. In a modified construction the cutter 6, Fig. 2, is carried by the link 14 of the pantograph pivoted at 3 on the rotatable shaft 2 and the tracer 8 is mounted on an extension of the link 13. The handle 10 is carried by a separate pantograph 17, 18 pivoted on a rotatable shaft 20 and connected at its middle point to the tracer 8. The scale is adjustable by displacing the link 14 parallel to itself, as shown dotted, and for traversing large models the pivotal point of the levers 17 on the shaft 20 may be displaced. In a further modification the tracer 8 and cutter 6, Fig. 3, are both carried by a link 27 of a pantograph attached to a rigid frame 28 or a rotatable shaft and the handle 10 is attached to the link 27 by links 30 and extensions 29a of the links 29. The distance h of the handle from the frame may be varied by adjusting the lengths 20a, 30 as shown dotted. The frame 28 may be slidable transversely to the plane of the pantograph and the handle may be attached to a bar slidably guided through the point 10 and mounted on the point of intersection of the links 29, 29a. In another modification the pantograph is duplicated about the axis perpendicular to the frame 28 and passing through the point 10, the tracer and cutter being mounted on opposite sides of the point x, and the handle is carried by a double pantograph pivoted at its middle point at x and connected at its inner end to an arm projecting laterally from a rotatable shaft replacing the frame 28. This form retains a large ratio of h : t but reduces the overall dimensions of the apparatus.
