14) using a hot-plate
test, mirtazapine demonstrated an antinociceptive effect at a dose of 10 mg/kg; however it was found to be partially ineffective at a dose of 15 mg/kg.
In order to calculate % maximal antinociceptive effects (% MPE), tail-flick and hot-plate
latencies (in seconds) were converted to percent antinociceptive effect using the following equation: % MPE = [(Postdrug latency-Baseline latency) / (Cutoff value -Baseline latency)] x 100.
Two grades of polypropylene filled with 20% and 30% of talc, the latter a flame-retarded grade, were welded by the hot-plate
Two fixtures, capable of holding two 2-inch-long pipes separately, were installed on a hot-plate
An infrared system to replace hot-plate
welding and eliminate the need to touch parts in order to get the plastic heated for bonding is in development.
Chinese supplier of hot-plate
welding machines for PE and PP pipe.
welders offer high-strength welding capabilities and hermetic sealing.
of sales, says the new product offers the "ultimate" in control of hot-plate
Method is said to bond more strongly at lower cost than hot-plate
welding, and is also an alternative to super-heated air and cold metal heat-staking methods used in the automotive sector.
IR welding has potential for replacing hot-plate
welding methods, says Heraeus Noblelight sales manager Ed Arneson.
Also to be shown are vibration, hot-plate
, and spin welders.
Also in place are a paint line, glass-bonding equipment using Dow's Betaseal polyurethane adhesives, and ultrasonic and hot-plate
, ultrasonic, and spin welders; and hot-air/cold-staking machines.
laser welding appears likely to evolve into a joining method for niche applications where it offers cost or performance benefits over proven alternatives like ultrasonic, vibration, and hot-plate
Precise servo control, instead of standard pneumatic or hydraulic actuation, is said to allow a new hot-plate
welder to assemble parts with wall thicknesses down to 1.
