Abstract: A METHOD USING INDUCED POLARIZATION      FOR ORE DISCRIMINATION IN DISSEMINATED EARTH DEPOSITS        Abstract of Disclosure A method for establishing data related to the complex resistivity of selected sub-surface earth deposits whereby increased discrimination and identification of ore deposits is established.  The method utilizes induced polarization in the earth with establish-ment of both time domain and frequency domain data and correlation of such data with an analog equivalent circuit of the earth section to derive a value closely approximating the complex resistivity of the selected earth substructure thereby to provide more dis-criminating data enabling determination of the percentages and types of sulphide ore deposits.

Abstract: WIRE LINE CLAMP FOR USE IN A DRILLING APPARATUS            ABSTRACT OF THE DISCLOSURE      An improved wire line clamp is attached to the circulating head atop a string of drill pipe and permits remote clamping from the drill rig floor.  The wire line, or conductor cable, is clamped in the grove of a sheave used to lower the cable into the drill string by means of an arcuate clamping shoe that matingly engages with the cable in the sheave groove.  The clamping shoe is pressed into engagement by means of a clamping pin attached to a vertically movable cross member that extends across the top of the sheave and that is attached to a U-shaped support means positioned above and attached to the sheave axle.  The cross piece has on each end two collars in which are located hydraulic rams, or the like, for providing a downward force upon the collars and thus the cross piece and clamping shoe upon actuation.

Abstract: A self-locking coin receptacle and cover therefor for use in coin-controlled machines.  In one embodiment described herein the cover is formed as an assembly of channeled members, the first being a rectangular open-bottom member and a second member adapted slidably telescopically to be received within the first member.  The first member carries a window alignable with the coin delivery chute of the coincontrolled machine.  The second member carries a coin container, the entrance thereto being aligned with the window.  A narrow longitudinal slot in the first member opens to the window.  A spring biased slide is installed on the floor of the channel defined within said first member.  The slide operates to cover and uncover the window.  A spring catch mechanism is provided for operation between a set condition to permit the slide to be urged against its normal bias for uncovering the window when the assembled container is installed in the machine, and a latched condition subsequent to the removal therefrom.  Simultaneously with removal of said assembly from the machine, the slide is returned to cover the window, closing off access to the container other than by removal of the cover therefrom.  A hooked detent is capable of being biased into the opened window whenever the window is partially or fully uncovered.  A follower is secured to the detent and is ridable in a guide slot positively forcing the hooked end into the window and retract the same only when the window is closed.  The detent prevents removal of the assembly from the receptacle unless the window is covered fully. Several spring catch mechanisms are operable on the slide for preventing undetectable uncovering of the window subsequent to removal of the assembly from the machine.  The first and second members must be separated to gain access to the container and to reset the spring catch mechanism.  The cover assembly is suitable for use with a rigid coin box and with a flexible coin bag.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for and method of making an automobile sound insulat-ing panel are provided herein.  The method is an improvement in a method of making a sound insulating panel for an automobile and comprising the steps of, forming a contoured fibrous pad, coating the pad with a liquid plastisol layer, and curing the plastisol layer.  The improvement resides in a coating step which comprises the steps of continuously moving the pad on a conveyor having openings therein, disposing an open top elongate trough vertically above the conveyor and pad, and flowing en-tirely by gravity a solid curtain of liquid foamed plastisol from the trough against at least one surface of the pad while continuously moving the pad thereunder, the curtain extending across one full dimension of the pad while moving the pad at a constant speed through the curtain.          Upon curing, the automobile sound insulating panel is provided in which the plastisol layer is bonded against the pad.  The plastisol layer com-prises a foamed plastisol layer having randomly disposed air pockets therethrough.  Such pockets serve to reduce the overall weight of the panel while improving the acoustical properties thereof.

Abstract: INJECTIVITY PROFILE LOGGING FOR TWO PHASE FLOW                   (D#74,463-1-F) ABSTRACT OF THE DISCLOSURE         Fluid injectivity within an interval in a well bore is determined by injecting into the well two fluid streams, one of which flows down the tubing and one of which flows down the  annulus,  each of said  fluid streams  containing a different radioactive tracer.  The fluid stream injected into the tubing contains a radioactive tracer that is soluble almost exclusively in the liquid phase of the fluid, while the  annulus  fluid stream contains a radioactive tracer soluble almost exclusively in the gas phase of the fluid.          The sum of the two fluid flow rates is held constant while each flow rate  is varied against the other.  At each different pair of flow rates,  stable interfaces will be formed between the gas phase in the tubing and the gas phase from the annulus as well as the liquid phase in the tubing and the liquid phase from the annulus.  The position of these stable interfaces at each different set of fluid flow rates is measured by a conventional gamma ray well logging tool, and from the series of such measurements an injectivity log for both fluid phases over the measured interval can be determined.                             -I-

Abstract: ABSTRACT OF THE DISCLOSURE A container closure comprising a cap and an annular ring connected to the cap by a bridge.  The annular ring includes a laterally extending span or weakened portion having lesser tensile strength than the remainder of the ring.  When the cap is rotated to loosen the cap, the annular ring is constricted radially inwardly, thereby abutting the container neck and frustrating removal until either the bridge or span is broken.  A broken bridge or span indicates both visually and by touch that the closure has been tampered with.  In a preferred embodiment, the cap and annular ring are integrally molded from plastic as a unitary structure.
