A torque limiter is a mechanical device that prevents mechanical overload by controlling the amount of torque the drive shaft is subject to. It can completely decouple the load or allow it to slip during overload. There are several designs, including shear pins, synchronous magnets, bawl catch and pawl, friction plates, magnetic particles, and magnetic […]
Logarithmic amplifiers correct input signal shifts by converting them to a constant output voltage. They are used in electrical circuits, medical devices, video circuits, fiber optics, and wireless devices. Advances in technology have made them more efficient and there are now three types: log DC, baseband, and demodulating. Each type has its own specific usage […]
Knurling is a process of cutting or rolling patterns into materials like plastic or metal, often used to improve grip on handles or knobs. It can be done on a lathe with rollers or with hand tools, and can create diamond, crisscross, or straight line patterns. Knurling is a method used to cut or roll […]
A midi lathe is a small lathe for turning small wooden objects, suitable for home joineries and large-scale factories. It has a more powerful motor than mini lathes and can support larger workpieces. Accessories are available, and it can be purchased new or used. It’s ideal for beginners and experienced carpenters. A midi lathe is […]
Plasma actuators use ionized gas to create aircraft control surfaces without moving parts or hydraulic systems. They offer greater reliability and maneuverability, but altitude and speed affect performance. The technology is practical and has been tested in wind tunnels at supersonic speeds. A plasma actuator is a form of advanced servo mechanism developed primarily for […]
Industrial automation uses robotic devices for manufacturing tasks, saving money on employee benefits and allowing plants to run 24/7. While machinery can be expensive, it leads to significant savings and eliminates the need for many jobs, which can be a disadvantage for workers. Industrial automation is the use of robotic devices to complete manufacturing tasks. […]
A sharpening jig is a device used by carpenters to sharpen metal tools at a precise angle for consistent results. It consists of a body and clamp to hold the tool in place, and can be made from wood or metal. While it offers benefits such as extending the life of a tool, users must […]
Electric hoists are smaller, more environmentally friendly, and quieter than traditional cranes. The jib crane is mounted to a wall or floor, while the overhead crane moves along metal beams. Both are used for precise lifting in factories, warehouses, and construction sites. Cranes have been a useful construction and manufacturing tool for centuries. This simple […]
A hand lathe is a woodworking machine that spins a stock to allow a craftsman to chisel and create products with perfect radial symmetry. Most modern lathes for hobbyists turn stock into wood with variable speed electric motors. The hand lathe has been adapted to be operated by a single individual with various mechanisms allowing […]
A blast cabinet is a contained space used for high pressure blasting activities, ranging in size from small closets to large industrial spaces. They are used for tasks such as paint stripping and metal polishing. Blast cabinets feature different operations, including built-in sandblasting equipment and openings for manipulating equipment or objects. They are equipped with […]
The drive frame is crucial in mining as it drives additional conveyor segments and keeps the system steady and secure. It must be made from strong materials, contain few bolted parts, and be compatible with the carrier system. Bushings are used to allow movement and can be replaced easily. A drive frame is an integral […]
Rapid prototype models are created from computer drawings and allow customers to review products under development. 3D software and printers have revolutionized the process, allowing for virtual testing and the creation of physical samples using plastic, metal, or powder. Some products are designed entirely in CAD software, eliminating the need for physical prototypes. Test software […]
A belt sander is good for removing large amounts of material, but hand sanding is necessary to remove scratches. A random orbital sander removes less material and prevents scratches with its unique motion. It works well for removing paint, smoothing joints, and curved surfaces. When purchasing, be prepared to spend $50-200 and consider a dust […]
A subarachnoid hematoma is a dangerous accumulation of blood under the second brain membrane, which can lead to strokes, seizures, and brain damage. Causes include physical accidents, arteriovenous malformation, aneurysms, blood disorders, and idiopathic reasons. Symptoms include loss of mobility, unconsciousness, and nausea. Early detection and treatment can prevent death, and surgery can repair aneurysms […]
A rotary table is a metalworking device used for precise positioning of workpieces, with manual or numerical control. It can be used with indexing plates and is often mounted horizontally or vertically to facilitate concentric cutting operations. It is versatile and used for various machining and milling procedures. A rotary table is a disc-shaped metalworking […]
A rough terrain forklift is an outdoor machine used to lift materials over unstable surfaces. It has a stronger construction, special tires for traction, and is found on construction sites, farms, and military bases. It comes in two configurations and can lift heavier loads than a standard forklift. A rough terrain forklift is a piece […]
A plucker is a machine used to remove feathers from poultry during processing. It can handle various types of birds, but heavier birds may cause problems. Plucking methods include wet, dry, and wax. The process is forceful but does not damage the bird’s skin or muscle tissue. A plucker is an automated machine made to […]
Fall protection includes various equipment and policies to minimize the risk of injury to workers operating tasks elevated above ground level. It includes devices like guard rails, safety harnesses, and inflatable devices. Different sub-categories like fall arresters and restraint devices are also used. The use of fall protection is mandatory in some industries, and the […]
Spill response involves containing and cleaning up hazardous material spills. The response varies based on the materials involved and available resources. The goals are to contain the spill and clean it up. Governments and businesses have spill response plans in place. Spill response” is the term used to describe the activity that takes place after […]
Nuclear decommissioning is the process of safely shutting down and removing hazardous materials from a nuclear facility. It can be performed by specialized companies and government agencies, with options including complete decommissioning, secure storage, or burial. Careful planning and administration are necessary, and the lifetime of a nuclear facility varies. The safe storage of nuclear […]
