Abstract: A cable compression die assembly is used in connection with a compression tool for compressing a stranded cable prior to crimping. The cable compression die assembly includes a pair of cable compression die heads for receiving a stranded cable and a cable connector therebetween. The pair of cable compression die heads defines a hexagonal shaped opening therebetween and is adapted to substantially close the hexagonal shaped opening as the die heads move towards one another.

Abstract: An apparatus for mixing fluids within a pipe is provided. In one embodiment, the apparatus includes a fluid mixing device with a pipe having a pipe wall and an axial bore for conveying fluids through the pipe. The fluid mixing device also includes a sleeve disposed about the pipe and a cavity provided between an exterior surface of the pipe and an interior surface of the sleeve. The cavity and the axial bore of the pipe are in fluid communication with one another via an opening through the pipe wall. Additional systems, devices, and methods are also disclosed.

Abstract: An apparatus for mixing fluids within a conduit and monitoring performance of the mixing is provided. In one embodiment, the apparatus includes a conduit and a fluid mixer coupled to the conduit for mixing fluid flowing through a bore of the conduit. The apparatus also includes multiple sensors for measuring a characteristic of the fluid at different locations in the bore of the conduit downstream from the fluid mixer. A controller of the apparatus can monitor performance of the fluid mixer in mixing the fluid flowing through the bore of the conduit based on the measured characteristic of the fluid at the different locations in the bore of the conduit downstream from the fluid mixer. Additional systems, devices, and methods are also disclosed.

Abstract: The cable embedding device is used to install a cable, such as a copper cable, together with filler material within a void trenched into the surrounding land area. The cable embedding device has a hopper, and a chute extending from a lower end of the hopper. The chute includes a plowing edge attached to a leading edge of the chute. A tube is connected to the device inside the hopper and extending along a major axis of the chute. An arch is formed at a lower edge of the chute.

Abstract: A portable and programmable biofeedback system which senses a physiological variable, such as heart rate, and both displays the physiological variable in a visual display in real time and activates and deactivates a user prerecorded voice-message upon reaching a user-programmed threshold value for the physiological variable measured. The system is especially useful in the field of behavior modification which require that the patient have reliable access to his or her behavior modification techniques upon onset of the symptoms associated with a diseased behavior.

Abstract: The process involves creating an internal lining in a bore, e.g., for repairing well casings. A plurality of layers of resilient strip material having an adhesive material, in uncured condition and interspersed between overlapping surfaces of the strip material and between the outer surface thereof and the bore, are applied in spiral fashion by means of a mandrel to the portion of the bore to be lined. Pressure is then applied to the internal surface of the liner to force the liner against the inner surface of the bore, preferably by inflation of a packer or packer assembly whose length is substantially the length of the liner, until the adhesive is cured. The mandrel for creating the liner in a bore includes a portion adapted to receive the spirally-wrapped strip material, a packer at the upper end of the wrappable portion of the mandrel and a packer terminating at the lower end of the wrappable portion of the mandrel and extending therebelow.

Abstract: An improved hold-down arrangement for a copy sheet pickoff system in which a pressure finger of insulating material is mounted on the removable transfer corona assembly in such a way that when the assembly is placed in operative position on the machine the pressure finger is located adjacent to the forward edge of the pickoff blade with the operative end of the finger spaced out of contact with the drum by a distance which is approximately equal to the thickness of a sheet of copy paper.

Abstract: Music playing apparatus for playing selected musical notes in accordance with a selected rhythm pattern. A rhythm pattern is selected having a multiplicity of intervals. The rhythm pattern is repetitively reproducible and musical notes played at any interval within the rhythm pattern may be selectively played as either an unaccented note or as an accented note. Selected musical notes are played at each interval within the rhythm pattern and the pitch of a selected note is determined. The pitch of a selected note is within a predetermined range of octaves in the chromatic scale and this range of octaves may be selectively extended. A tone generator generates audible musical tones in accordance with the established rhythm pattern, the selected musical notes, and the octave band within which the selected musical notes are found.

Abstract: A clutch for stopping lateral motion of a first element or device, such as a print head in a data printer, which moves along an elongated second member such as a rod or bar. The clutch includes a movable clutch member with an aperture through which the elongated bar passes. In a data printer, this bar may be the guide bar along which the print head moves laterally. The print head or other such first member is coupled to the clutch member to move it along the bar so long as the clutch member is aligned generally normal to the bar, in which condition the bar passes freely through the aperture in the clutch member. An actuator aligned with the clutch member along its lateral travel path is put into position at a point along such travel path where it is desired to stop the moving print head or other device, and operates to tilt the clutch member so that it cocks into engagement with the bar. This produces a binding action which prevents any further movement of either the clutch member or the primary device (e.g.
