Abstract: ABSTRACT OF THE DISCLOSURE     An improved geophysical exploration system includes a seismic cable, in-cable electronics, high data capacity recording equipment, and means for transmitting data from approximately 500 equally spaced elemental sensor units.  Signals representing seismic waves received at each of these 500 units are transmitted from the cable to a central control and recording unit mounted in a towing ship.  Connected to the cable are one or more array-forming systems for processing seismic data from the sensors.  In combining signals from the individual sensor units making up each array, the array-forming apparatus may increase the relative weighting of signals from selected sensor units in each array and may vary the relative delay between signals arriving at different sensors making up an array.  A simplified array former may selectively simulate various known forms of seismic cables, including those normally employed for land and shallow water surveys and different arrays normally used for deep water surveys.       To enhance the high frequencies which are characteristic of shallow reflections received at sensors close to the shot point, the data from cable sections closer to the shot point are sampled at a higher rate such as 2,000 samples per second for an initial period such as the first one second or so of the recording time.  Thereafter, the sampling rate is reduced to 1,000 samples per second, as data from the entire cable is sampled.

Abstract: AN APPARATUS FOR IMAGE MANIPULATION     Abstract of the Disclosure An image can be represented by an M x N array I (*,*) of image points, where each point I(i,j) over the ranges O?i?M and O?j?N is a value or set of values representing the color and intensity of an elemental portion of the image.  A black/white image can be represented by assigning to each point I(i,j) a value of 1 or O.  Thus, I(i,j) = 1 represents a black elemental image area, while I(i,j) = O represents a white elemental area.     Image manipulation refers to that class of image processing opera-tions which sequentially process the points of a rectangular array I(0,0), I(0,1),... I(0,n-1), I(1,0),..., I(M-1, N-1) in such a way that the resulting points must be mapped into coordinate points of the array.  The image processing operations satisfying this constraint include the blanking of an image area, the combining of two images, the changing of scale of an image by a rational amount, rotation by 90°, and the creation of a mirror image.     Image manipulations in the invention are performed upon black/white images by logically combining a base image stored in an accumulating memory with a sequence from another raster source subject to selective size and translation changes.  Such processing is subject to two con-straints.  First, the data must be in non-compressed form.  Second, the processed data must not fall outside the memory space originally occupied by the base image in the memory.  Optionally, the function of magnification/minification may be performed separately from the other image manipulations.  This can be conveniently done by placing the magni/minifier between the external image source and a network, which network logically combines the serial information from the external source with the serially extracted base image information stored in the accumulating memory.

Abstract: ABSTRACT OF THE DISCLOSURE           A power saw having a power housing, a cutter bar, a saw chain mounted to travel around said cutter bar and a safety brake for stopping the saw chain.  The saw has an improved device to provide for automatic release of said safety brake.  That device comprises a blocking mechanism for holding the safety brake in a non-braking position.  The cutter bar is mounted in the saw in a manner to permit short pivotal movements upwards from its normal position relative to the body of the saw.  There is a mechanical release mounted in the saw and coupled to the cutter bar to receive a force transmission from an upward movement of the cutter bar.  The release is associated with a spring loaded trigger action mechanism for triggering the release in response to the pivotal movements of the cutter bar.  The effect is to release the blocking mechanism and cause the brake to be applied.  The brake is applied immediately following a jerky movement of the cutter bar.

Abstract: DEVICE FOR DETECTING UNBALANCED CONDITIONS       IN A POLYPHASE EQUIPMENT BANK ABSTRACT:  A sensing device is connected to an intermediate tap point on each phase leg of a poly-phase system such as a grounded wye-connected capacitor bank to detect faulted capacitor units and thereby control a switching device to isolate the capacitor bank.  The intermediate tap point is selected in each phase leg such that the number of series units (such as parallel capacitor groups) above the tap point equals (or exceeds by one) the number of series units below the tap point.  The outputs of these sensing devices are coupled through a calibration network to a summing amplifier which operates to add the three signals vec-torily to produce an AC output signal that is filtered by a 60 Hz band pass filter to attenuated unwanted harmonics and noise which might introduce error into the measurement.  Initial balance is achieved by adjusting the magnitude of each phase to ground signal to equalize those signals from each of the intermediate tap points.  Thus, an artificial neutral is created at the summing amplifier and filter output when the output is adjusted to a null.  By this adjustment, the output signal of the summing amplifier and filter is then proportional to the per cent unbalanced among the three intermediate tap point voltages.  The per cent un-balance output signal is directly related to the change in voltage occurring at the tap point due to faulted capacitor units.  The output AC per cent unbalance signal is rectified to a proportional DC voltage and applied to a meter that is calibrated to read the capacitor bank tap-voltage percent unbalance due to loss of individual capacitor units.  The DC voltage is also fed to a level detector which has an adjustable reference level setting means.  This level detector can operate a control circuit when the tap-voltage per cent unbalance attains a corresponding level such that the voltage across the surviving units in a series group exceeds the recommended maximum working voltage.          Avoidance of false operation due to transient voltages (caused by bank switching or system disturbances) is accomplislled by a timing circuit which requires the signal to persist for a selectable period of 4 to 30 seconds before an operation is initiated.  When the unbalance persists at the preset level for the pre-selected time period, a latching relay is operated which can actuate an alarm or a switching device to isolate and protect the capacitor bank.  The device also incorporates a gross overvoltage circuit which functionally bypasses the level detector and the timing circuit to achieve fast isolation of the polyphase system in the event of a massive fault.

Abstract: Abstract This earth boring drill apparatus has a cutter mounting leg extending from one side of a drive stem and a removable cutter assembly, including a fixed shaft and cutter journaled for rotation on the shaft supported between the drive stem and the mounting leg. The stem has a bore for slidably receiving the inner end of the shaft.  The cutter mounting leg terminates in an end surface extending parallel to the axis of rotation of the bore and shaft. A shaft supporting lug projecting from the outer end of the shaft has a surface which is parallel to the end surface on the leg.  The opposed surfaces respectively have a V-shaped projection and mating groove which provide lateral alignment and prevent shaft rotation while permitting the shaft to be movable in an axial direction by an amount sufficient to permit the shaft to be withdrawn from the bore.  Bolts extending between the mounting leg and the shaft at an angle clamp the mating surfaces of the groove and projection together and also clamp a pair of flat spacers between the mounting leg and the outer end of the shaft to lock the shaft in the bore.

Abstract: ABSTRACT:          The display device according to the invention uses a cell with liquid crystal provided between polar-isers.  The polarising means and analysing means are constructed and positioned so that the light transmission is zero at a voltage Vm on the cell, said voltage Vm being larger than the voltage which corresponds to the optical threshold of the cell.  The transmission of the cell as a function of the supplied voltage increases considerably above the voltage value Vm. The device is controlled by means of signal voltages which exceed Vm and which show a small voltage swing, while simul-taneously a strong light transmission and a good con-trast are obtained, which permits of using an informa-tion addressing according to lines and columns when a large number of lines are used.
