Abstract: An adhesive bound pad of paper such as loose leaf binder paper is provided which is secured in assembly by adhesive material, lining or partially lining holes along selected edges of the paper stack forming the pad. The edges of the paper pad remain free of adhesive material and thus are not distorted upon separation of the sheets from the pad. The adhesive bound pad is manufactured by assembling a selected number of sheets of paper into a stack and drilling or otherwise forming holes, such as binder holes, along one of the edges of the stack. Thereafter, the coating of adhesive material is applied within the holes of the stack so as to entirely coat the paper at the holes or to coat selected portions of the paper at the holes as desired. After the adhesive material has been allowed to cure or has been cured the paper is releasably retained in adhesive bound pad form and the manufacturing process is complete. Individual sheets of paper may be pulled away from the pad.

Abstract: A method and apparatus for processing discarded rubber tires and rubber tire material to reduce the same to a pulverulent form of sufficient quality fiber the manufacture of other articles. Principally the rubber tire is subjected to repeated compression against the metal strand component of the tires thus causing the metal stranding to cut into or chew the rubber into a pulverulent form. During the processing of the rubber tire material it is broken down to the point that its constituents such as metal fibers and polymer fibers are separated therefrom. The pulverized rubber, together with its separated constituents may then be classified and the constituents separated for further use. The rubber tire processing apparatus incorporates an external housing structure and a rubber processing drum that is rotatable therein.

Abstract: A method and apparatus for downhole formation testing is provided for acquisition of a phase intact sample of connate fluid by direct or indirect pumping for filling of pressure containing sample tanks that are removable from a formation testing and sampling instrument for phase intact transportation to a laboratory facility. One or more fluid sample tanks contained within the instrument are filled with connate fluid samples in such manner that during filling of the sample tanks the pressure of the connate fluid is maintained within the predetermined range above the bubble point of the fluid sample. The sample tank incorporates an internal free-floating piston which separates the sample tank into sample containing and pressure evacuation chambers. During indirect pumping a positive displacement piston pump draws fluid from the pressure evacuation chamber and permits formation pressure to shift the separator piston as the first variable volume chamber is filled with a connate fluid sample.

Abstract: A method and apparatus for safely controlling detonation of a downhole explosive energized device which ensures that the explosive can be detonated in a well bore only when downhole hydrostatic pressure and well fluid temperature are within limits reflecting location of the explosive energized device at designed depth for accurate positioning relative to a selected formation. The apparatus further employs a clock/timer circuit and a motion sensor circuit to ensure firing of the explosive device only within a predetermined time period and only after having remained stationary within the well casing for a predetermined period of time. The apparatus further includes a memory circuit which receives and stores pressure and temperature data sets correlated with time which reflect well conditions before and after firing of the explosive device. After the tool has been retrieved from the well, this data is copied from the tool memory to a computer memory for subsequent computer processing and display.

Abstract: A pinch resistant toilet seat insert is provided for use in combination with conventional toilet seats to restrict the dimension of the opening thereof to facilitate safe and effective use by children. A seat insert body forms an outer peripheral recess at the sides thereof or at the sides and rear portions thereof for supported and positioned engagement with the inner peripheral portion of a conventional toilet seat. The forward side edge portions of the seat insert body are relieved so as to locate the frontal contact points of the insert and the conventional toilet seat so as to be virtually inaccessible to the tissues of the child and to thus minimize the possibility of pinching the child during use. The seat insert body forms outer peripheral channels to conduct accidentally spilled liquid between the seat insert body and the conventional toilet seat so that it will drain into the toilet.

Abstract: A method and apparatus for reaming foreign deposits from the flow passage of well production tubing and cleaning deposits from the completion profiles within the tubing as well as for drifting the production tubing while located within a well bore. A reaming tool is extended through the tubing string and is rotated for reaming operations. A plurality of reaming dogs of the tool are selectively and radially expanded to tubing and tubing completion profile reaming positions by cams of a hydraulically operated linearly removable actuator mandrel. The actuator mandrel is spring-urged toward a position permitting spring-urged retraction of the reaming dogs so that the reaming tool may be introduced into or withdrawn from the tubing string by linear movement.

Abstract: There is disclosed in the present specification a method and apparatus for use of a downhole formation multi-tester instrument in the characterization of formation fluids, including measurement of the conductivity of water, often in the presence of hydrocarbons under dynamic flow conditions and determining the hydrocarbon volume of the formation fluid. Utilizing a coaxial transmission line as a flow tube within the formation multi-tester instrument an electromagnetic wave is generated which propagates through the formation fluid in a transverse electromagnetic mode. Measurement of the phase shift and attenuation of the electromagnetic wave at points within the flow tube allow characterization of the fluid inside the cavity of the flow tube for dielectric constant and conductivity. Dielectric constant and conductivity can then be related to fluid conductivity and hydrocarbon volume.
