House fire in Chicago Ridge, 11-1-18
From the Chicago Ridge Police Department's Facebook page:
Check out this inspiring message: "When you wear different uniforms, but play for the same team… No matter the patch, we are all still family!" It’s a beautiful reminder of unity and collaboration.
Today, I want to highlight an incredible effort by the Chicago Ridge Fire Department. They recently responded to a house fire on Oxford and Washington this afternoon. The firefighters did an amazing job putting out the blaze, and they received great support from multiple neighboring departments—North Palos FD, Burbank FD, Bedford Park FD, Bridgeview FD, and Oak Lawn FD. These agencies truly came together as one big team when it mattered most.
I also want to commend Officers Kaspar and Jenen for their quick thinking. Not only did they help the homeowner safely retrieve their two dogs, but they even located the family’s two cats after the fire was under control. Thankfully, no one was injured during the incident, which is a testament to the hard work and dedication of everyone involved.

This story really highlights how communities come together in times of crisis. Whether you’re in red or another color of uniform, everyone plays a vital role in keeping our neighborhoods safe. Let’s give a round of applause to these brave first responders!
Induction heating coil is a device that uses the principle of electromagnetic induction for induction heating. It is commonly used for heating metal materials, such as in industrial processes such as welding, heat treatment, and melting. The working principle is to generate eddy currents (induced currents) inside the heated metal through the alternating magnetic field generated when alternating current flows through the coil. This eddy current in turn generates its own magnetic field and interacts with the original magnetic field, causing heat to be generated inside the metal and achieving heating.
The design and application of induction heating coils have the following key points:
1. Induction coil structure: The coil is usually made of conductive materials such as copper or aluminum, and its shape and size are designed according to specific application requirements. It can be circular, square, or other shapes. The number of turns, diameter, and wire diameter of the coil can affect heating efficiency and power output.
2. Frequency selection: The efficiency and effectiveness of induction heating are related to the frequency of use. High frequency (several kilohertz to tens of megahertz) is suitable for rapid heating of thin-walled components, while low frequency (several hundred hertz to several thousand hertz) is more suitable for uniform heating of thick walled components. According to the frequency of induction heating equipment, it can be divided into high-frequency induction coils, intermediate frequency induction coils, ultra-high frequency induction coils, and ultrasonic induction coils
3. Power control: By adjusting the current input to the induction coil, the heating power and temperature can be controlled. This function is usually achieved using electronic devices such as thyristors and inverters.
4. Induction cooling system: In order to protect the heating area from overheating, an induction cooling system may be required, especially during continuous heating operations.
5. Safety measures: Induction heating equipment must be equipped with effective safety measures, including preventing electric shock, avoiding spark splashing, and ensuring good ventilation in the operating environment.
Induction heating coils are widely used in various fields such as metal processing, automotive manufacturing, aerospace, medical equipment, etc., and are one of the indispensable high-efficiency heating technologies in modern industry.
