Title: Processing of seismic data obtained with long shot-detector distances
IPC: G01V1/28
Filed: 1968-05-30
Abstract: 1,217,932. Seismic signal processing. MOBIL OIL CORP. 30 May, 1968 [31 May, 1967], No. 26016/68. Heading H4D. [Also in Division G1] For synthesizing shallow reflection events from field traces recorded using large shot-to-detector distances and thus having no identifiable primary reflections from shallow reflection horizons but having multiple reflections generated by these horizons, those portions of the traces representing reflections following the direct refraction waves are selected, corrected for normal moveout, auto-correlated and applied, with or without further processing, to a visual recorder. Static corrections, and inverse filtering to remove the effects of shot pulse variations, may be applied to the field traces prior to the selection step. The selection step prevents noise in the first-break portions of the traces from producing erroneous results in the autocorrelation process. The autocorrelator may be operated to produce only one half of each autocorrelation function, since the functions are symmetrical about the zero time shift position. Those portions of the autocorrelation functions following the main peaks at the zero time shift position may subsequently be auto-convolved (by the further processing) and recorded to provide a further synthesized record containing predominantly first order surface multiples.  The processing may be done in the time domain or frequency domain and by analogue or digital means. Details are given of an optical unit for the autocorrelation or autoconvolution.

Filed: 1920-09-18
Abstract: 174,129. Broadhurst, H. F. Sept. 18, 1920. Bottling granular, pulverulent, and like materials.-In filling bottles, tins, or other receptacles by difference of pressure, either above or below atmospheric, three separate tubes communicate with the interior of the bottle, viz. : a suction pipe c to conduct liquid from the supply tank to the bottle, a vacuum pipe d to withdraw air from the bottle, and a breaker pipe e to admit air to the bottle after the vacuum is shut off when the bottle is filled and so break the vacuum, correct the level and drain off the filling and vacuum pipes c, d, e, before the nozzle is raised in the bottle. The apparatus can be used for filling containers with powders. The tubes c, d, e, are carried by a head a, and a soft washer f of india-rubber &c. is arranged round the tubes to make an airtight joint on the top of the bottle. On inserting the nozzle in the neck h of the bottle and removing pressure from the inside. of the bottle by the pipe d, the tube e being closed to atmosphere, liquid is drawn up the suction pipe g and through the tube b into the bottle until the level therein reaches the end of the tube d. The tube d is then shut off from the pump by means of a valve located at some distance from the nozzle, and the tube e opened to atmosphere. The liquid in the suction pipe falls back into the supply tank, drawing back any slight excess of liquid in the neck of the bottle and all the liquid in the filling- tube b and nozzle c, and leaving the level of the liquid in the bottle at the bottom of the nozzle, c. Any liquid that has enter the tube d is drawn towards the pump and may be trapped if desired, so that when the nozzle is lifted out of the bottle there is no drip. Any number of bottles can be connected to vacuum and breaker tubes, common to all.

Abstract: 1528519 Rectangular to polar coordinate transformation FORD AEROSPACE & COMMUNICATIONS CORP 28 June 1976 [27 June 1975] 26885/75 Heading G4A  A binary signal representing the polar coordinate angle # of a vector or phasor is derived from binary signals representing the rectangular coordinates Re, Im of the vector or phasor and stored in registers 12, 14. The most significant bit of # is the same as the most significant bit of Im and is entered, via lines 46 and 24, into an address counter 16 which also receives the second most significant bit of # from an exclusive OR gate 42 receiving the most significant bits of Re and Im. The third most significant bit of #, entered in address counter 16, is derived from an exclusive OR gate 48 receiving the most significant bit of Im and, via a flip-flop 42, the sign-bit output of an adder/subtracter 62 receiving Re and Im via selector gates 88, 84; adder/subtractor 64 is controlled to add when the output of exclusive OR gate 42 is 1 and to substract when the output of exclusive OR gate 42 is 0. When the three most significant bits of # have been entered into address counter 16 the fourth most significant bit position of address counter 16 is set to 1 and all less significant bit positions are set to 0 to provide a test angle #t. A programmable read-only memory 22 and a multiplier 126 then form Im cos #t and Re sin #t and adder/subtractor 62 forms (Im cos #t-Re sin #t) = P sin (# - #t) where P is the amplitude of the vector or phasor. If the output of adder/ subtractor 62 is positive then # is greater than #t and a successive approximation register 134 maintains the fourth most significant bit position in address counter 16 at 1 whereas if the output of adder/subtractor 62 is negative # is less than #t and register 134 changes the fourth most significant bit position in address counter 16 to 0. In either case this procedure is repeated for the fifth most significant bit of # and successively for all less significant bits until P sin (# - #t) is found to be zero. P may then be found by using memory 22, multiplier 126 and adder/subtractor 62 to form the sum Im sin # + Re cos # = P.

Title: Improvements in or relating to a process for making diketene
IPC: C07C45/88
Filed: 1933-09-30
Abstract: <PICT:0410394/IV/1> Diketene is produced by polymarizing a solution of ketene in acetone while avoiding the simultaneous presence of high temperature and high concentration of ketene.  Preferably the temperature should not exceed 25 DEG  C. and the concentration of ketene should not exceed 10 per cent.  The acetone employed for the production of the ketene should be completely dry; it may be produced in that condition by refluxing with acetic anhydride. The reaction gases from the pyrolysis of acetone may be absorbed in cooled acetose and the dilute solution allowed to stand at ordinary temperature for the polymerization; or the reaction gases may be treated to condense most of the acetone and then passed into acetone cooled by solid carbon dioxide, the solution being then allowed to come gradually to room temperature.  In an example, the reaction gases from a copper converter are passed through a brine-cooled condenser A, in which the unchanged acetone condenses and dissolves the ketene to form a dilute solution which collects in a receiver B in which it is allowed to come gradually to room temperature.  Uncondensed gases pass to a scrubber C containing a solvent for ketene such as the dilute solution of diketene from the receiver B or a liquid which will react with ketene such as water, acetic or other carboxylic acid, an alcohol, or aniline.
