Verma comes to…
Smallest Known Asteroid Characterized Using Earth-Based Telescopes
Astronomers have obtained observations of the smallest asteroid ever characterized in detail. At 2 meters (6 feet) in diameter, the tiny space rock is small enough to be straddled by a person in a hypothetical space-themed sequel to the iconic bomb-riding scene in the movie “Dr. Strangelove.” Interestingly, the asteroid, named 2015 TC25, is also…

The newest product line from Dorner — the 3200 series conveyor with Intralox Activated Roller Belt (ARB) Technology — was on display at PackExpo earlier this month, along with several other key technologies from the conveyor manufacturer. The 3200 series is ideal for moving boxes and packages in applications that require merging, diverting and alignment. […]
Maintaining productivity and minimizing downtime with HPMB bearings
HPMB bearings are suitable for use in water turbines, gates and other hydropower needs. Hydropower is a critical source of renewable energy, which is why turbines and other important pieces of equipment cannot experience unscheduled downtime. With that in mind, GGB created the HPMB bearing, featuring dimensional stability, high load capacity and corrosion resistant materials. […]

ROBA-DS shaft couplings tested by DNV GL
The compact ROBA-DS disk pack couplings by mayr power transmission have been certified by DNV GL. They ensure maximum safety for users on the high seas. Whether in the drives of ship propellers, mobile platforms such as drilling platforms for oil and gas extraction, or also in tidal power plants – the areas of application […]
Faster Design When Working With Large Data Sets: 2017 IronCAD Design Collaboration Suite
There’s a good chance engineering companies that work with extremely large data sets across both two- and three-dimensional environments use IronCAD for design. On November 30, the company introduced its 2017 IronCAD Design Collaboration Suite, which makes it faster for users to work with large data sets, thus reducing design time from concept to production […]
R+W Releases STE safety coupling with elastomer connection
R+W has recently narrowed the gap between its classic precision and industrial drive safety couplings with the new STE series. Featuring the well proven technology of the ball-detent safety element system, which disconnects drivelines within milliseconds of a torque overload event, this version is more cost effective and available in smaller sizes than the standard […]
Quaker Chemical Buys Metalworking Fluids Maker Lubricor for $11.8 Million
Quaker Chemical Corp. acquired Lubricor Inc., an Ontario-based metalworking fluids manufacturers and marketer, the companies announced this week. The deal was completed for C$16 million – or US$11.8 million. Lubricor sells about US$10 million of branded products directly to North American customers, mostly automotive supplies, as well as to customers in Southeast Asia through a…
How linear force-current relationships from linear motors improve motion
Applying an electric motor is easier when one knows what it will output for a given input. The simpler it is to predict that, the more elegant and robust the design. To this end, some linear motors have linear force-current relationships so engineers don’t need to accommodate nonlinear effects through approximation or additional terms in […]

NASA’s Cassini Spacecraft Explores the Outer Edges of Saturn’s Rings
Cassini is about to become Lord of the Rings — Saturn’s rings, that is. The NASA spacecraft, which has been exploring the Saturn system since 1997, has entered into the final phase of its mission, thanks in part to a gravitational nudge from Saturn’s moon Titan. Engineers have been pumping up the spacecraft’s orbit around…

FAQ: Can I use anyone’s filament or powder in my 3D printer?
The answer is, it depends. The history of 3D printing includes a time when engineers turned away from using these devices because they could not deliver a quality built part. Vendors went back to the drawing board and designed new printers, using advanced technology that came about during that time period, that could build objects […]
First Signs Of Weird Quantum Property Of Empty Space?
By studying the light emitted from an extraordinarily dense and strongly magnetized neutron star using ESO’s Very Large Telescope, astronomers may have found the first observational indications of a strange quantum effect, first predicted in the 1930s. The polarization of the observed light suggests that the empty space around the neutron star is subject to…
