The Robust H05BQ-F Harmonized Cable That Even Smokey the Bear Could Endorse

Posted on 9/30/25 2:45 PM

Polymer pioneers in the 1960s and 1970s experimented with multiple thermoplastics to create a low-smoke and zero-halogen (LSZH) cable for the wire and cable industry. Despite achieving low-smoke low-halogen (LSLH) cable, the work of these scientists and engineers was not in vain—in 1979, Richard Skipper of the Raychem Corporation in Menlo Park, California, developed a thermoplastic infused with aluminum trihydrate to create the first LSZH thermoplastic. Aluminum trihydrate [Al(OH)₃] is a white, odorless powder derived from bauxite and commonly used as a flame retardant. The new patent greatly minimized flames and smoke when subjected to intense heat. According to the universal Harmonized Wire Coding System (a one-page download available at the end of this article), the alpha-numeric code of H05BQ-F lets users know the cable is LSZH because of its specific jacket and insulation compositions, as well as its fine-wire flexibility. This cable is further described in paragraph four.

“Rock Out” with a Double-pole, Single-throw Rocker SwitchRocker Switch

Posted on 7/30/25 10:16 AM

A switch is an electrical component used in equipment to “switch” power on and off—technically its function is to open and close a circuit. An open circuit (indicated by a “O” on the rocker) turns devices off, and closing them turns the device on (indicated by a “—” on the rocker) which allows the current to flow again. While it sounds somewhat backwards, it’s the nomenclature of electrical circuits.

Is This the Golden Age of Medical & Industrial Robotics?

Posted on 6/30/25 11:57 AM

In 1983, the first surgical robot, Arthrobot, was used to accurately align a patient’s leg during an orthopedic surgery. In 1985, the PUMA 560 robot assisted in a brain biopsy providing precise tissue sampling. The da Vinci robotic-assisted surgery (RAS) system by Intuitive Surgical debuted in 1998, and received FDA approval in 2000 for laparoscopic surgery. In 2014, the da Vinci Xi was the new system’s advanced version enhancing flexibility, imaging, and instrument control. And in 2023, da Vinci added transoral procedures to its list, all which minimize recovery times through less invasive surgeries. The da Vinci 5 added tactile feedback for the surgeon to “feel” the tools move along soft tissue during surgery, which Intuitive calls Force Feedback technology. It received FDA 510(k) clearance in March of 2024.

Part II: American Manufacturing—Past, Present, & Future

Posted on 5/29/25 2:19 PM

Americans have a reputation for having a down-to-business and self-reliant work ethic that started during its first Colony in Virginia (1607), to its thirteenth Colony (Georgia, 1732). Forty-four years later, Jefferson penned the Declaration of Independence on July 4, 1776, and self-reliance was on a roll. Once the war was over, America began to export its goods, and its first tariff was enacted by the First Continental Congress in 1789 “ . . . to lay and collect Taxes, Duties, Imports and Excises . . . to regulate Commerce with foreign Nations," which was signed into law by George Washington. Tariffs have been used throughout U.S. history—the U.S. government was funded by tariffs until 1913. After that, it was a combination of taxes and tariffs.
