Abstract: The present invention relates to an inner pin base for a three-pole plug.  The inner pin base has a round-sectional passageway at a top portion and two channels at two sides of a bottom portion.  An upper and a lower rims of the passageway extend backward to form an upper and a lower tongue pieces, respectively, allowing a ground terminal to pass through while a projected portion on a top surface of the lower tongue piece engages with an oval hole at the end of the ground terminal passing therethrough.  The channels each has a vertical and slender slot formed at their substantially closed front end, allowing a positive or a negative terminal to pass through.  Two parallel stops extend backward from two internal sides of each vertical and slender slot and each has two vertically spaced projected portions inwardly extending toward the slender slot such that the vertically spaced projected portions of the parallel stops engage with dents formed on the positive and/or the negative terminals when the terminals are separately inserted through the vertical and slender slots. In this manner, the inner pin base allows convenient assembly of the terminals and provides considerable strength to hold the assembled terminals so that the inner pin base along with the assembled terminals may be directly positioned in a mold for injection molding to form a finished three-pole plug.

Title: Method for producing an interference-free radio connection
Inventor: BURCHARD THOMAS
IPC: G08C17/00
Filed: 1993-04-30
Abstract: ABSTRACT OF THE DISCLOSURE           In a method for channel scanning by the receiver of a teleaction system, the squelch signal of the HF part of the receiver is scanned for the presence of an HF signal on the tuned-in channel, and only after that, depending on the outcome of this scanning, are further switching or evaluation processes of the receiver initiated.  As a result, the channel search conventionally employed is speeded up substantially by scanning the received telegram addresses without requiring additional effort or expense, since the squelch signal is already available in any case in the conventionally used standard components from which HF receivers are assembled.
Patent CA-2096229-A1 (CA)
Title: Optical mixing device
Inventor: JENKINS RICHARD M
IPC: G02B6/28
Filed: 1991-12-02
Abstract: An optical mixing device (10) incorporates a rectangular multimode waveguide (14), with an input region (22) and an ou-put region (24), two square section input waveguides (26, 28), and a detector (34). The input waveguides (26, 28) are arranged to provide first and second input radiation beams respectively to the input region (22), each beam being in the form of a square waveguide fundamental mode beam. Modal dispersion along the multimode waveguide (14) produces a single maximum incident on the detector (34) when the input beams are in phase with one another, and two maxima of like magnitude located on opposite sides of the detector (34) when the input beams are in antiphase. Intermediate these two situations three maxima are produced, the amplitudes depending on phase difference. The first and second input beams may be of like frequency producing a time-inde-pendent device output. The input beams may alternatively have different frequencies. For instance the first input beam may be a local oscillator signal produced by a coherent source of stable frequency, and the second input beam may be a Doppler shifted version of an output signal from that source. The device output then provides an intermediate frequency signal. The intensity inci-dent on the detector (34) thus varies at the difference frequency of the two inputs. Similar devices may be constructed with addi-tional inputs and with different forms of output.
