Abstract: ABSTRACT OF THE DISCLOSURE     A soil sample core extraction tool having a handle member on which is movably mounted a soil probe member and a clutch arranged for selectively preventing movement of the soil probe with respect to the handle member. By sequential actuation and release of the clutch, the depth of the probe member into the soil being sampled becomes independent of the position of the handle member relative to an operator, thus permitting the operator to manipulate the handle member from a convenient position during the entire sampling operation. A cleaner is removably attached to the handle member for facilitating removal of a core sample from a sampling tube of the probe member and permitting subsequent lubrication of the sampling tube in order to eliminate resistance of the tube to insertion into a soil being sampled.

Abstract: CORE ASSEMBLY IN A COUPLER FOR A       RAILWAY VEHICLE               ABSTRACT OF THE DISCLOSURE            A novel core assembly is used in a sand mold for casting a hollow section in a coupler head extending beyond a horn line into a coupler shank of a coupler for a railway vehicle.  The core assembly includes head and shank core members having face surfaces each including a recess surface and a projected surface arranged such that the recess surface in the head core receives the projected surface in the shank core.  In a similar way, the recess surface in the shank core receives the projected surface in the head core to maintain the head and shank cores in an aligned abutting relation while supported in the sand mold.          The face surfaces extend transversely to the coupler shank along a parting line spaced rearwardly of the plane containing the horn line of the coupler.  The face surfaces are further characterized by a conically-shaped projection extending from one core member into a conically-shaped opening in the other core member to mechanically interconnect and align the two core members.  The head and shank cores each includes concave side wall sections terminating at the face surfaces to pro-duce cast protrusions in the hollow section of the coupler shank at the parting line between the core members.

Abstract: ABSTRACT OF THE DISCLOSURE         A control circuit is disclosed for use in a switching-type regulator which includes a source of unregulated DC voltage, a switching circuit for interrupting the unregulated DC voltage to produce an AC voltage having a duty cycle which is a function of the operation of the switching circuit, a converter for con-verting the AC voltage to a regulated DC voltage, a controllable pulse generator for supplying pulses of controllable duration to the switching circuit so as to determine the duty cycle of the AC voltage, a feedback circuit responsive to  variations in the regulated DC voltage for controlling the duration of the generated pulses to maintain the regulated DC voltage at a desired level, and disabling circuit for selectively limiting the operation of the pulse generator.  The control circuit is used to reset the disabling circuit to an initial state and to change gradually the duration of the pulses which are generated by the pulse gen-erator when the regulator first is turned ON.  By resetting the disabling circuit, there is no  limitation on the operation of the pulse generator at the outset.  By gradually increasing the duration of the pulses generated by the pulse generator, the so-called "soft start" operation is performed, whereby the regulated DC voltage gradually is increased from a zero level to its desired level.  The control circuit includes a voltage generator for gen-erating a control voltage which increases rapidly during an initial interval and then increases at a significantly slower rate after it attains a first level.  The disabling circuit is reset when the control  voltage reaches its first level; and when the control voltage thereafter increases at a much slower rate, the slowly-in-creasing control voltage is used to correspondingly increase the duration of the generated pulses, whereby the level of the regulated DC voltage likewise increases.

Abstract: A BULLDOZER BLADE                     ABSTRACT OF THE DISCLOSURE         A blade for a bulldozer.  The blade comprises a post of variable, substantially circular cross section varying from a maximum at the top and the bottom uniformly to a minimum at the middle.  The post is attachable to a bulldozer.  A blade member is pivotally mounted to each side of the post.  Each blade member is shaped at its inner end to correspond to the shape of the surface of the post.  The blade is adapted to attach to, for example, hydraulic rams to pivot each blade member independently about the post.          Thus, upon pivoting, each blade moves around the post while at least maintaining a uniform, small distance from said post.

Abstract: ABSTRACT    An improved bypass valve for use with an oil well testing string is disclosed which includes a check valve means for allowing fluid flow from the interior of the test string to the well annulus when the interior pres-sure exceeds the well annulus pressure.  The bypass valve further includes a blocking means which blocks interior communication with the check valve means when the well annulus pressure exceeds the string interior pressure.          A delay means is included which delays the action of the blocking means for a predetermined length of time.  The improved bypass valve is intended for use in a testing string for an oil well, and is to be placed in the test-ing string below a normally closed tester valve and above a seal assembly for insertion into sealing engagement with a preset production type packer.  The time delay allows the seal assembly to be removed from the packer after the packer location is determined without activat-ing the blocking means to move to its locked closed posi-tion.

Input signals, which simulate the rotation of automobile wheels, are supplied to a processor-controller.  One selected input signal is held at a substantially fixed frequency while the other input signals occur at a decreased frequency.  The processor-controller adopts the substantially fixed frequency input signal as a reference signal.  The frequency of the input signals are then varied according to a predetermined sequence, and the brake control signal emitted by the processor-controller is monitored.
