Title: Improvements in or relating to fluid pressure measuring apparatus
Inventor: BAILEY WILLIAM HEAP
IPC: G01F23/18
Filed: 1960-01-19
Abstract: 960,583. Differential hydrostatic pressure gauges; liquid level indication. DAVY & UNITED ENGINEERING CO. Ltd. Feb. 6,1961 [Jan. 19, 1960], No. 1909/60. Headings G1H and G1L. To determine the level of a hydraulic liquid in a reservoir 12, Fig. 4, the difference in pressure between a pressurizing gas above the surface 67 (69) of the liquid and a fixed level 16 below the surface, is transmitted by diaphragms 31, Fig. 2, in separate chambers 28, 29, of a transducing device 20 to electrically non-conducting fluids in pipes 21, 22 whereby the height of mercury 50, Fig. 3, in the cavities 45, 46, separated by wall 44, varies as a function of the pressure difference and thus the level of liquid in reservoir 12. As the height of mercury in the central cavity rises, successive ones of the electrodes 41 complete a circuit to give an indication, for example, by means of flashing lamps, to operate control equipment. A baffleplate 51 prevents rapid movement of mercury to reduce splashing into ports 47,48, run-back ports 53, 54 being also provided. Evaporation and condensation of the reservoir liquid will add liquid pressure to the upper pipe 15 but by inclining this and providing a tube 64 widened at its upper end and filled with liquid, a constant liquid head is provided and the correction can be calculated.

Title: Improvements in or relating to tobacco cutting machines
IPC: A24B7/02
Filed: 1935-01-21
Abstract: 449,266. Balancing reciprocating parts of machinery. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd., East Street, Bedminster, and ROBERTSON, A., 19, Clarendon Road, Redland, both in Bristol. Jan. 21, 1935, No. 1912. [Class 80 (iv)] [See also Group I] To balance the forces due to the movement of the reciprocating knife 10, knife head 9, and connecting rod 14 of a tobacco-cutting machine, a subsidiary balance-weight 20 is secured to a shaft 21 rigid with yoke-arms 22 attached by pivots 23 to the frame 1 ; a link 24 extends from the shaft 21 to ears 26 on the connecting rod 14 that extend at right angles to its main middle line opposite the centre of the crank-pin 15. The balance weight 20 and its associated parts are equal in effective weight to the knifehead 9 and its associated parts. As the two masses reciprocate in directions at right angles to each other with substantially harmonic motions their dynamic effect is the same as an equal weight situated at the crank-pin and rotating therewith ; this equivalent weight is balanced by a counterweight 27 on the main shaft 16. An improved balancing effect may be arranged by also providing two shafts 28, 29 carrying counterweights 30, 31, and coupled together and driven by gear wheels so as to rotate in opposite directions at twice the speed of the shaft 16.

Title: Method and apparatus for geophysical seismic exploration
IPC: G01V1/34
Filed: 1966-01-14
Abstract: 1,098,360. Seismic prospecting. ESSO PRODUCTION RESEARCH CO. Jan. 14, 1966 [Jan. 18, 1965 (2)], No. 1932/66. Heading H4D. [Also in Division G2] In a system for providing a time-varying two-dimensional display the visual effect of which is the same as if one were viewing seismic waves appearing on the earth's surface as the result of a single induced seismic pulse, light intensity-modulated in accordance with the amplitude of seismic signals which would be detected at a plurality of spaced geophone locations is transmitted to the display area by an optical system including an array of elongated light-wave guides. In a first embodiment, seismic impulses are generated by a dynamite, dropping weight or vibrator source positioned sequentially at 2500 points arranged on a 50 by 50 grid and are detected by a geophone or geophone cluster located at the centre of the grid (Fig. 2, not shown). Separate seismogram traces for each impulse point are recorded photographically or magnetically and converted to variable-density or variable-area traces on a film negative 125 (Fig. 3) by processor 123. The traces have a common time origin and are arranged in side-by-side groups on film 125, each group corresponding to a different one of the fifty lines of impulse points. Film 125 is moved past a linear light source 129 to modulate the intensity of light incident on one end of a fibre-optics unit 131 comprising fifty ribbons, each made up from a plurality of fibre-optics strands. Those ends of the ribbons adjacent to film 125 are linearly arranged edge-to-edge so that each ribbon scans a different trace group, while the opposite ends of the ribbons are stacked to form a raster end 135. A magnified image of end 135 is viewed on a screen 139, areal points of which correspond to points on the impulse grid. Seismic " events " appear on the display as rings centred on the screen centre and gradually increasing in diameter (Fig. 14, not shown). Details of the fibre-optics unit 131 (Figs. 4 to 9, none shown), and mechanical system for moving film 125 past unit 131 (Figs. 10, 11 and 15, none shown) are given. A method for extending the subsurface coverage by using three detection locations on a line through the impulse grid centre is described (Fig. 13, not shown), and details of other prospecting methods including a method for providing continuous subsurface coverage (by generating a seismic impulse at each of several locations spaced along a first line, detecting reflected signals at each of several locations on a second line substantially orthogonal to the first and then transferring all impulse locations and detecting locations in a given direction by a distance which is one-half the length of the detecting geophone array) are given. In an alternative embodiment in which continuous waves, rather than pulses, are induced in the earth, the traces to be processed are " correlograms" derived by correlating a detected seismic signal with a counterpart of the seismic signal transmitted into the earth and recording the correlation result.

Abstract: 1364254 Ultrasonic inspection devices; light modulating CENTRAL ELECTRICITY GENERATING BOARD 27 Jan 1972 [19 Jan 1971] 2469/71 Headings H4D and H4F Ultrasonic echo signals from an article under inspection are passed through a transparent medium and rendered visible at a time and location at which the individual echo components are in focus to produce an image of the internal structure of the article. Electrical pulses from source 4 are fed to transducer 5 connected to article 6 via a nosepiece 5A. The echoes are focused by an arrangement comprising fused quartz blocks 2, 3 and a container 1 full of mercury. Source 4 is also connected to a stroboscopic light source 8 via a delay 7. Source 8 illuminates block 2 through polarizing filter 9 with pulses of 0À5 microsecond duration or less. A camera or observer views block 2 through polarizing filter 10. Delay 7 is adjusted so that source 8 illuminates block 2 when echoes from 6 are focused in the block, the block being of photo-elastic material so that a visible image is formed. In the embodiment of Fig. 2 (not shown) a transducer (25) activates the article (26) in synchronism with strobe (28), the ultrasonic image being formed in water contained in glass cell (31). The focusing arrangement comprises a steel block (23), a lenticular body of mercury (21) and a plano convex quartz block (22). The strobe illuminates the cell through a mask (29) and lens (32), the visible image being formed at a knife edge (30) via a lens (33). The image is projected by a lens (34) on to a screen (35). The optical system may be simplified by omission of the lenses and screen and the image observed directly at (30). A modified optical system using graticules (49), (50) is illustrated in Fig. 3 (not shown). Various arrangements of the transducer, steel and nosepiece assembly used in Figs. 2, 3, are illustrated in Figs. 4 to 8 (not shown). The above assembly may also be designed so that shear waves are transmitted to the article rather than longitudinal waves, the shear waves reflected from defects being converted back to longitudinal waves on re-entering the nosepiece.
