Abstract: A pump comprising a bore pump fluid end having a reciprocating element bore, a discharge valve assembly comprising a discharge valve seat and a discharge valve body, and a suction valve assembly comprising a suction valve seat and a suction valve body; a hollow, cylindrical reciprocating element; a hollow reciprocating element adapter comprising a first end having a fluid inlet opposite a second end having a fluid outlet, wherein the second end of the reciprocating element adapter is connected to and in fluid communication with the fluid intake end of the reciprocating element; a pump power end having a push rod connected to the first end of the reciprocating element adapter; and a movable manifold comprising a reciprocating element end and a fluid intake end, wherein the reciprocating element end of the movable manifold is connected to and in fluid communication with the fluid inlet of the reciprocating element adapter.

Abstract: An electrical connector has an insulative housing and a plurality of terminals. The insulative housing has a base and a tongue. The terminals are mounted in the insulative housing by an insert-molding process. Each terminal has first and second positioning tabs formed transversely on the terminal and embedded into the tongue to prevent the terminal from inadvertently moving relative to the insulative housing.

Abstract: An orthodontic set-up tray includes at least two sections, and each section includes at least one receptacle for receiving an orthodontic appliance. A coupling movably connects the sections together to enable relative movement between the sections. The coupling advantageously permits the overall size of the set-up tray to be reduced or enlarged as may be desired by the practitioner. Optionally, the coupling is a releasable coupling that enables the sections to be detached from one another.

Abstract: A board shaped electrical connector includes a rectangular female section 1 comprising a raised portion 11 in a lengthwise groove 111, widthwise channels 12 at either half, two side fastening blocks 13, and conductors 2 in the channels 12 and each including a U-shaped contact 21 having hooked ends 212, and a fastening member 22 including a projection 221 in the fastening block 13, and a first space 226 formed between the conductor 2 and the channel 12; and a rectangular male section 3 comprising top slopes 312, a lengthwise cavity 33, widthwise channels 34 at either half and being in communication with the slopes 312, and conductors 35 in the channels 34 and each including a U-shaped slip-resistant portion 353 at the other end. In an assembled state the male section 3 is inserted in the female section 1 with the conductor 35 fastened by the hooked ends 212.

Abstract: A submersible pump motor has rotor sections spaced apart from each other with bearings located between. The bearings support the shaft of the rotor within a stator. The bearing is stationary and has a cavity in its outer periphery. A metallic coiled member is positioned along the circumference of the bearing, and rests in the cavity on the outside diameter of the bearing. The coiled member engages the bearing and the inner wall of the stator to prevent rotation of the bearing.

Abstract: A connection terminal for use with a flat flexible connector comprises a base defining first and second sides. A pair of cantilevered arms extends forward from the base. Each arm forms a contact portion at a free end thereof. Characterized in that the contact portion has reduced thickness than the rest of the terminal.

Abstract: The present invention impresses the data on the power signal by utilizing a saturable core reactor. The saturable core reactor uses two cores. Each core has both load windings and control windings. The control windings are selectively energized to alter an electrical characteristic of the current passing through the load windings. The saturable core reactor is designed with cores made of a highly magnetically permeable material so that the cores are easily saturated. The cyclical saturation of the cores achieved by the load current, and the selective saturation of the cores achieved by selectively applying a control current, results in "deformations" being selectively formed at the zero crossings of the load current waveform. These "deformations" can be selectively formed on the power signal to represent a binary data stream.

Abstract: The present invention is a magnetic tape-based "voice mail" multi-user message system. The system transmits audio prompts to callers to help guide them through the various procedures. The callers respond with Touch-Tone commands. A novel circuit is provided to detect these tone commands without significant interference from the audio prompt signals. This circuit is highly insensitive to deviations in the impedance of the incoming telephone line from its expected value. A circuit is also provided to prevent Touch-Tone commands which are recorded on tape from being re-executed when they are played back from the tape. A single L.E.D. indicator on each recipient's telephone set indicates the status of the system: idle with new message waiting; idle without new message waiting; busy with new message waiting; or busy without new message waiting.
