Title: Seismic record sections
IPC: G01V1/24
Filed: 1971-12-20
Abstract: 1362670 Displaying seismic data WESTERN GEOPHYSICAL CO OF AMERICA 20 Dec 1971 59180/71 Heading H4D Wavelength variations in the acoustic waves propagated through subsurface formations of the earth during seismic exploration are represented on a coloured, depth-scale seismic record section as chromaticity variations. This enables received wavelets of the same frequency and associated with reflections from formations of different velocity characteristics to be distinguishably displayed, (Fig. 2B), whereas on a conventional time-scale section coloured according to wavelet frequency they would be indistinguishable (Fig. 2A). In the Fig. 1 system, data from a field seismic record are conventionally processed at 10 (e.g. edited, composited, cross-correlated) to reduce noise, then converted from a time-scale to a depth scale in a converter 14 programmed with RMS velocity data. Converter 14 output is split into wavelength bands by filters 16, 18, 20. The ratio of the energies of the filter outputs and the overall energy are determined by comparator 22 to provide respectively hue and lightness control signals which control respectively the beam mean vertical position and brightness in a cathode ray tube 26. The beam is oscillated horizontally, and slightly about this mean vertical position, by sweep generator 35, to illuminate a rectangular strip of a multicolour filter on the tube faceplate. The illuminated strip is imaged by optics 40 as a line on to a colour-sensitive recording medium 42 supported on a rotating drum 44. Individual colour projectors may be used instead of tube 26, or wavelength filters 16, 18, 20 may be used in sequence with medium 42 receiving a multiple exposure through respective colour filters used in sequence. There may be more or fewer wavelength filters, and conventional variable-amplitude or variable-area traces may be superimposed on the coloured display.

Title: Variable displacement pummps and motors
IPC: F15B9/08
Filed: 1970-12-16
Abstract: 1318317 Hydrostatic transmission control SPERRY RAND CORP 16 Dec 1970 [2 Jan 1970] 59624/70 Heading F2D [Also in Division G3] A swash plate 30 of a variable displacement pump or motor is carried by a yoke 32 rotatable in bearings 34 by a pair of servopistons 46 (only one of which is shown in Fig. 1) located on opposite sides of the axis of rotation of the yoke. The servopistons are biased by centring springs 50 and are controlled by valve 54 having abutting rotary discs 70, 72 (Fig. 11) coaxial with the axis of yoke 32. Disc 70 is controlled manually or automatically by spindle 71 and disc 72 is connected to yoke 32 to provide follow-up action. In operation, and considering rightward movement of disc 70 from the neutral position of Fig. 11, in which both servochambers 42 are connected to exhaust supply port 18, which receives control fluid from auxiliary gear pump 122, is connected via 80, 88, 114, 94, 90 to work port 120 leading to one of the servomotor chambers 42, and the other servomotor chamber continues to be exhausted via the other work port (not shown), (92), 96, 116. The yoke 32 will then be rotated until disc 72 has followed-up the initial movement of disc 70. To avoid the tendency of the discs to tilt when the disc 70 leads the disc 72 or travels beyond the angular range of movement of disc 72, as in hydrostatic transmissions requiring the motor to move from maximum displacement only after the pump has reached maximum displacement. The radial width of the grooves such as 96, 110 at the interface between the discs is made greater than the width of corresponding grooves such as 84, 102 in the opposite faces. The radial width of the recesses and lands at the interface may be chosen to tend to force the discs apart.

Patent GB-630714-A (GB)
Abstract: 630,714. Crank mechanism ; toothed gearing. CHOMET, (nee TREMOULET), J. M. A., and CHOMET, J. S. A. March 14, 1947, No. 7229. Convention date, Jan. 14. [Classes 80 (i) and 80 (iii)] [Also in Group XXVI] In a double-crank driving mechanism applicable to cycles or multi-cylinder steam or internal-combustion engines the two cranks are geared together with gears having sets of teeth of two different radii so that on the working stroke of one crank the other crank is driven on its idle stroke at a faster speed to pass beyond its top dead-centre position before the working crank reaches its bottom dead-centre position As shown in Fig. 1 two cranks 3, 4 rotating in opposite directions and subjected alternately to working forces F1, F2 respectively are provided with gears 5 and 8 with sets of inter-engaging teeth 6, 9 and 7, 10 of different radii. Crank 3 in moving from position 11 to position 17 on its working stroke drives crank 4 from position 14 to a position 18 beyond its top dead-centre ready for its working stroke on which it drives in turn crank 3 from 17 to 11. The final drive may be taken from either of the shafts 1 or 2 of cranks 3, 4, the speed of which will vary as the crank is rotated on its working and idle strokes. If a final constant speed drive is desired an arrangement such as in Fig. 5 may be adopted in which further gears 23, 24 are alternately engaged and driven by the sets of teeth of larger radii of the gears 5, 8. Alternatively the gears 5, 8 may both engage an intermediate gear with corresponding sets of teeth of different radii which will rotate at a constant speed. The arrangement in Fig. 4 provides for two cranks 3, 4 on aligned shafts 1, 22 rotating in the same direction. Gears 5, 8 with sets of inter-engaging teeth of different radii as in Fig. 1 are arranged on shaft 1 and an intermediate shaft 2 which is geared by ordinary gears 21, 20 to the shaft 22 of crank 4. This arrangement is suitable for a cycle. In a modification of this arrangement stepped gears are provided on each crankshaft engaging with correspondingly stepped gears secured together on the intermediate shaft which shaft will rotate at constant speed. The change from one set of gear teeth of one radii to the other set of different radii may be made progressive to reduce shocks.

Title: Article of furniture
IPC: A47C4/02
Filed: 1978-08-25
Abstract: An article of furniture, e.g. a chair, intended for supply in disassembled form has two tubular frame elements (1, 4), of which one may comprise a base frame and the other may support a back rest. One frame element (1) has attached thereto a tubular socket (3) which receives the other frame element (4) rotatably and slidably therein. When the article is disassembled the two frame elements (1, 4) may be folded to lie alongside one another. When the article is assembled the two elements are unfolded and are retained in relatively extended positions by means of a turned over lug. The lug on the one hand prevents withdrawal of the other element (4) from its socket (3) and on the other prevents relative sliding movement of the two elements by engagement with the underside of a further element, e.g. a seat support, secured to the one element (1). <IMAGE>

Title: A system for protection of an installation on the floor of a body of water
IPC: E02B3/04
Filed: 1978-11-23
Abstract: A flexible mat covering an installation on the floor of a body of water has edges resting on the floor which are thick and rigid so that a dragging anchor or fishing gear hooking the edge will roll up the mat or fold it accordion-wise and so be carried over the installation by the roll of mat formed. Elasticity of the mat and/or its edge causes the mat to roll back to resume its original configuration after the passage of the anchor or fishing gear. The mat may be of sheet material or of blocks joined together by various means or in the form of a bag filled with material or of scrap tyres. The mat may be laid over the installation from a reel on a lay-barge or from a manned or unmanned self propelled under water vehicle or it may be laid in sections. <IMAGE>
