Abstract: A method and system for geophysical exploration including obtaining, processing, displayind and interpreting seismic data. Seismic energy is imparted into the earth's subterranean formation along at least two linear independent lines of action in a seismic survey. At least two linearly independent components of the seismic wave energy imparted along each line of action are detected within the seismic survey. A concord of seismic signals is produced from the seismic wave energy detected for selected combinations of receiver and source locations. An orientation module operates on the concord of the seismic signals so as to generate synthetic concords of seismic signals so as to focus on a particular component of the seismic wave energy iny order to infer the geologic characteristics of the earth's subterranean formations.

Abstract: In a registration system for compensating for distortion of a test printed circuit board (12) relative to a stored reference in a printed circuit board inspection system fiducial marks on the test board are compared with fiducial marks on the stored reference to determine distortion of the test board with respect to the reference board. This information is utilized to load a memory (18d) so that exposure (EXP) pulses for a scanning CCD camera (11) can be read out at intervals which compensate for distortion in the scanning direction x. The fiducial information is also used to generate a pixel gate on the occurrence of each exposure (EXP) pulse to compensate for distortion in the y-direction. The exposure (EXP) pulses are further utilized to generate addresses to a buffer memory (19) storing the reference to cause patches representative of the reference board to be read out of memory in registration with patches representative of the couterpart surface location of the test board (12) to permit accurate real time comparison of the test board (12) with the stored reference.

Abstract: In a method and apparatus for controlling the solenoid current of a solenoid valve which controls the amount of suction air in an internal combustion engine wherein the actual current (Iact) flowing through the solenoid (7) is detected and a solenoid current control value (Icmd) is calculated as a function of engine operating conditions; a corrected solenoid current control value (Icmdo) is determined as a function of the solenoid current control value (Icmd) and a feedback control term (ifb(n)) is calculated as a function of the difference between the corrected solenoid current control value (Icmdo) and the actual solenoid current (Iact). An initial value (Ixref) for the feedback control term (Ifb(n) is determined as a function of an integration term (Iai(n)) which forms part of the feedback control term (Ifb(n)). A pulse duration signal (Dout) is determined as a function of the corrected solenoid current value (Icmdo) and an output pulse duration signal (Dout(n)) is calculated as a function of the pulse duration signal (Dout) and the feedback control term (Ifb(n)). Hereby the time period before the solenoid current reaches a value corresponding to the output pulse duration signal is shortened, and hence the engine rotational speed will rise rapidly to a predetermined rotational speed corresponding to the output pulse duration signal. 
     In another aspect, a predetermined non-operating current control value (Ig) is used as the corrected solenoid current control value (Icmdo) when the engine speed is above a predetermined value (Mg). 
     In still a further aspect, the output pulse duration (Dout(n)) is corrected as a function of   battery voltage (VB).

Abstract: Apparatus for separating granular material, such as crushed coal or ore, that includes particles of different specific gravity, comprises an elongated frame (20) supporting a receiving chute (27), a discharge chute (28) and a plurality of hydraulic cells (11, 12, 13, 14) in tandem. Each cell includes a wave chamber (38), a screen (47) forming a material supporting floor sub­merged in the wave chamber, a plunger (41) for cyclically raising and lowering the water level in the wave chamber and a refuse bin (51) for receiving heavier particles that are separated out in the wave chamber (38) and that collect above the screen (47). The wave chambers (38) define a flow channel (29) extending from the receiving chute (27) to the discharge chute (28) and which contains a suspension or slurry of the crushed particles. The plungers (41) for the cells operate to generate a wave which progresses from the upstream end to the downstream end of the flow channel, the plungers (41) having a decreasing stroke so that some reinforcement of the wave is provided but the amplitude diminishes gradually toward the downstream end of the flow channel. With this arrange­ment, the hydrodynamic separation proceeds from a rela­tively rough level to a relatively fine level at the down­stream cell (14). Accordingly, the downstream cell (14) has the capability of separating out even those particles relatively close in specific gravity to that of the desired particles.

Abstract: Intensive undercar cooling is achieved in the latter portion of a tunnel kiln by (a) a continuous undercar longitudinal cooling air flow or (b) by transverse undercar sub-chambers in which heat exchangers are used to set up local cooling connection currents within each sub-chamber. Air flows in the undercar channel are substantially prevented in the heat-up zone and up to about the middle of the firing zone. Pressure equalization is permitted with respect to the firing chamber thereabove but very little air will actually pass therebetween in the sensitive heat-up zone because there is no other substantial air passageway leading into or out of the sub-chambers formed by aprons depending from the kiln cars.

Abstract: The inventive method is particularly advantageous for the preparation of an unsaturated alcohol or aldehyde by the reduction of a corresponding unsaturated carboxylic acid since the unsaturated double bond in the starting acid is not hydrogenated by the reaction of reduction. The method comprises first reacting the starting acid with an alkyl chloroformate to form an intermediate compound by the dehydrochlorination and the intermediate compound is then reduced by using sodium borohydride as the reducing agent. The proportion of the aldehyde to alcohol in the product mixture can be controlled by modifying the amount of the reducing agent and/or the reaction time.

Abstract: A process control technique for upgrading C₃-C₄ hydrocarbon feed containing olefins to produce heavier liquid hydrocarbons comprising converting a major portion of C₃-C₄ olefins in an oligomerization zone by contacting a shape selective medium pore zeolite catalyst at elevated temperature and pressure to make distillate and olefinic gasoline. The oligomerization stage effluent is fractionated to provide distillate and gasoline product and a C₃-C₄ intermediate stream containing isobutane and unconverted propene and butylene. The C₃-C₄ intermediate stream is combined under control with a portion of C₃-C₄ feed and further converting the combined streams in an alkylation zone to make heavier paraffinic hydrocarbons. The olefin feed may be produced by catalytically converting methanol or similar oxygenated hydrocarbons in a known process. Controlled material balance is achieved by accumulating liquid olefin feed to the oligomerization and alkylation units using a surge drum with liquid level control. By-product isobutane is recovered and recycled under liquid level control operatively connected to determine feed of liquid olefin to the conversion units.
