Why Helicopter Crashes Are Deadly: A Call for Tighter Safety Regulations | High Quality Bronze Safety Valve

While many departments reply upon laptop, tablet and other GPS-enable devices for determining response routes, others make good use of map books that can provide additional information on building layouts and access, water supply and other details. Provisions for carrying multiple map books inside of the cab for each response district can provide valuable information for the crew. When combined with the jurisdiction’s standard operational guidelines (SOGs) for structural fires, the officer can establish where the apparatus should be positioned and points of access for the building. 

Adding to their collection of OSHA-compliant dust collection solutions, the Milwaukee SDS-Plus Dust Trap Drilling Shroud makes its debut. This one is pretty simple and it’s not terribly expensive.

High-speed cornering and changes of direction are where the true awesomeness of an F1 car’s performance can be displayed, and Melbourne has just the spot. Turns 11 and 12 make up an extremely high-speed chicane, where cars approach at 300km/h and pull nearly 5G laterally as they tackle the left-hander.

And I would point out the following things about transmission vs engine: 1. active for longer periods (100ms range) vs. 30ms for 1000rpm engine 2. number of activations is in the range maybe 1/s (worst case city very aggressive driving) vs 16/s engine idle 3. work with much lower and slower pressures (in an engine, you will have 9-10bars at end of compression, before detonating the fuel) 4. transmission solenoid failure will result in disconnection, whereas engine failiure can lead to sudden stall, which the transmission has to disconnect, otherwise wheels will lock-up. Engine damage is implied. From 1. and 3., there are 2 electrical conclusions: they need a lot (10x-100x) of electrical power to do the job. Which leads to thicker wires, massive transistors (with massive heatsinks) and massive EMI. In short…..way too expensive. The concept is nice, but you should already know that things don’t scale in linear fashion and sometimes researching another domain is less expensive than developing this (looking at you, electric cars!). Why use tons of electricity for valves when you can sent it to the wheels?

To make sure it corners and stops properly, Hyundai put over 6,000 test miles into its i30 N prototypes around the Nürburgring during development, completing the 24 Hour race with a pair of their almost stock pre-production cars as well.

For fast and efficient drilling, the combination hammer puts out 19.4 joules of energy and 290 rpm using a 60-volt/12 amp-hour battery and brushless motor. Seven speed selections for drilling and chipping help tailor the force of the machine to the material at hand.

The angle markings are just etched in the plastic, so there’s no contrast to help you see them. A little paint would be good, etched metal plating would be better.

“It’s been a long winter with a lot of theories and speculation going around, but the race track is where we settle all that. We had a good winter test, I’m growing happier every time I step into the car and the first race will be especially exciting.”

Slides, rotary valves, everything is on the table. My goal with this piece is to get people thinking – and building.

At just under $140, the Drill Doctor 750X gives you the most versatility out of the current options. If you’re committed to sharpening your broken and dull bits to get more life out of them, it will pay over time. You’ll realize your return on investment even sooner if you’re using cobalt bits that are more expensive than black oxide and titanium.

Gilkey splashed from beyond the arc, then hit another jumper to push the Lady Tigers’ advantage back to 10 points. The sophomore guard shot 10-for-20 from the field and connected from deep twice.

wtf HaD? Just doing away with [continue reading] and putting the whole wall of text out front? As if the poor spelling and grammatical errors arent bad enough…
