Utility supplies: Smart tools — New Hilti SDS-max combihammers TE 60-AVR and TE 60-ATC/AVR | 4 Inch Handle Butterfly Valve

The inside door panel on this apparatus is equipped with a full height stainless-steel panel, LED warning light and angled handrail. Note the red color webbing over the door strap, which can be used to assist personnel entering the crew cab area.There are different options for valve controls on the front intake, including an external manual butterfly-style, air-operated and electric actuator controls. Each style of valve control has advantages and drawbacks; however, if an electric actuator is preferred, then specify an easily accessible manual override to enable the engine chauffer to open the valve in the event of a system failure. One of the principal missions of the engine company is to rapidly secure a reliable water supply and whether this entails having the first-due engine apparatus lay a supply line or hook up to an available hydrant. Well-designed engines should be able to bring in a water supply from several positions on the apparatus to ensure an adequate and reliable water supply. 

Example: A fire starts in a supply room of a large office suite on the 32nd floor. Several packages of Styrofoam® coffee cups rapidly ignite and fill the suite with smoke. Workers flee their cubicle work stations and trample each other in a stampede to the elevators. Tunnel vision sets in, and panic completely disables their brains from thinking of something as basic as exiting to the stairwells. That is the reason trained civilian fire wardens are so vitally important. Fire wardens who take their responsibilities seriously can prevent this havoc and save their co-workers’ lives by thinking for them when they cannot think clearly for themselves, taking charge and directing them to exit stairwells.

You might think that a bit strong enough to drill through concrete could also handle steel, but a masonry bit’s tip and flute geometry are completely different—thicker and blunter, meant to pulverize. Also, the hammer drill was probably in percussion mode, which simultaneously pounds and drills through concrete, stone, or asphalt. That percussive action broke the bit when you hit steel. Even if you’d switched to rotary mode, it wouldn’t have helped. The bit may not have broken, but it wouldn’t have made any real progress through the steel.

Is it really a bad idea to light a cigarette while pumping gas? I don’t think the science is settled!

At least part of this is thanks to the helical design, which uses spiral flutes instead of just progressive gradations. Even after all of this use, I can still see the side markings clearly since they’ve been shielded from wear inside the spiral.

That triangular hole in the subframe is the airbox intake. For me, the only stylistic miscue on the bike is the passenger peg, which just begs to be removed for a cleaner look, and – what do you know – KTM sells a sporty passenger seat cover!

• While I respect not going with obvious artists, opening the season of a show with a lead named Shadow Moon with a song called “I Cast a Lonesome Shadow” is a bit eye-roll-inducing. Better music cues in the diner: “The Fool” as we first get there and “Everybody Walkin’ This Land” during the massacre.

Exactly when, and how fast a valve opens is determined by the profile of the cam lobe. Auto racing and performance enthusiasts often change camshafts to those with more aggressive profiles and different timing offsets depending on the engine’s requirements. Everything comes at a cost though. A camshaft machined for maximum power generally won’t idle well and will make the engine harder to start. Too aggressive a lobe profile can lead to valve float, where the valves never fully seat at high RPM.

*Luckily I dodged that bullet. The delicate digestion (IBS), shoddy eyes, and depression is more than enough…

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?

The top line of the bracket was churning Saturday. First, Tennessee lost at Auburn 84-80, which caused the Volunteers to drop down to a No. 2 seed. Then, North Carolina completed the season sweep of Duke, 79-70, which moved the Blue Devils down to the No. 2 line for the first time this season. With that victory the Tar Heels moved up to replace Duke.
