In the final step, the molded component and core are both demolded and the core is melted-out from the molding. This is done in a hot bath, via induction heating, or through a combination of the two. Hot baths usually use a tub filled with glycol or Lutron, which is a phenol-based liquid. The bath temperature is slight... | Wikipedia - Fusible core injection moulding - Melt-out |
In typical commercial applications the parts are dipped into the hot bath via an overhead conveyor. The advantage to using a hot bath is that it is simpler than induction heating and it helps cure thermoset moldings. The disadvantage is that it is uneconomically slow at a cycle time of 60 to 90 minutes and it poses env... | Wikipedia - Fusible core injection moulding - Melt-out |
Typically the hot bath solution needs cleaning or replacement every year or every half year when used in combination with induction heating.For thermoplastic moldings induction heating of the core metal is required, otherwise the prolonged heat from a hot bath can warp it. Induction heating reduces the melt-out time to... | Wikipedia - Fusible core injection moulding - Melt-out |
Another disadvantage is that the induction coils must be custom built for each molding because the coils must be 1 to 4 in (25 to 102 mm) from the part. Finally, induction heating systems cannot be used with moldings that have brass or steel inserts because the induction heating process can destroy or oxidize the inser... | Wikipedia - Fusible core injection moulding - Melt-out |

Richard Feynman claimed to be the only person to see the explosion without the goggles provided, relying on a truck windshield to screen out harmful ultraviolet wavelengths.

The VIPs viewed the test from Compania Hill, about 20 miles (32 km) northwest of the tower. The observers set up a betting pool on the results of the test. Teller was the most optimistic, predicting 45 kilotons of TNT (190 TJ). | Wikipedia - Trinity bomb - Personnel |
He wore gloves to protect his hands, and sunglasses underneath the welding goggles that the government had supplied everyone with.

In the final years of World War II, Nazi Germany researched and developed low-cost anti-tank weapons. Large anti-tank cannon firing high velocity projectiles were the best option, but costly to produce and required a well trained crew. They also lacked mobility on the battlefield once emplaced. Anti-tank rocket launche... | Wikipedia - High-Low System - Origin |
Recoilless rifles used a huge amount of propellant to fire the projectile, with estimates ranging from only one-fifth to one-ninth of the propellant gases being used to push the projectile forward. The German military asked for an anti-tank weapon with performance in-between that of the standard high velocity cannon an... | Wikipedia - High-Low System - Origin |
This concept was called the "Hoch-und-Niederdruck System" which translates to "high and low-pressure system". With this system, only the very back of the cannon's breech had to be reinforced against high firing pressures. Rheinmetall designed an anti-tank cannon using their "high-low pressure system" that fired a stand... | Wikipedia - High-Low System - Origin |
Such charges are now commonly called high-explosive anti-tank (HEAT) warheads or projectiles. Unlike high-velocity armour piercing ammunition, which has a heavy steel case, the shaped charge had only thin metal wall, reducing the weight of the shell body and increasing the explosive payload. A round steel plate with ei... | Wikipedia - High-Low System - Origin |
A rod attached the 2.7kg round to the plate with a shear pin. On firing, the initial pressure (which had to be quite high in order to reliably and effectively burn the propellant) would be contained in the shell casing, which along with the reinforced breech acted as the "high pressure chamber". Propellant gases would ... | Wikipedia - High-Low System - Origin |
Unlike standard cannons, in which the propellant accelerates a projectile out a barrel with an very high, almost instant force, to maximum muzzle velocity, the Rheinmetall concept pushes a projectile out a barrel at a slower muzzle velocity. As a shaped charge was used, no need exists for the high velocities of convent... | Wikipedia - High-Low System - Origin |
The Rheinmetall solution required only a lightweight recoil-unit and muzzle brake. The 81 mm weapon weighed significantly less than even the obsolete 50 mm cannon and Allied 57 mm guns, less than a seventh of the weight of the 88 mm Pak it was to supplement, and less than a tenth of the weight of the famous 88 mm anti-... | Wikipedia - High-Low System - Origin |
At over 500 meters, this was superior to both the German long barrel 75 mm cannon, and the American 76 mm gun, even when the latter was equipped with tungsten high velocity armor-piercing rounds. The Germans ordered the Rheinmetall gun into production, designating it as the 8-cm Panzer Abwehr Werfer 600 (PAW 600). Only... | Wikipedia - High-Low System - Origin |
In the final years of the 18th century, Italian scientist Giuseppe Maria Giovene (1753–1837), in his work Avviso per la distruzione dei vermi che attaccano la polpa delle olive (1792), provided some suggestions for peasants to effectively destroy the fly musca oleae, which infested the pulp of olive trees. | Wikipedia - Bactrocera oleae - History |
In the final years of the war, Nazi Germany produced a wide array of radical aircraft concepts. Some of these did not progress beyond initial design stages.

In the finery, a workman known as the "finer" remelted pig iron so as to oxidise the carbon (and silicon). This produced a lump of iron (with some slag) known as a bloom. This was consolidated using a water-powered hammer (see trip hammer) and returned to the finery. | Wikipedia - Finery forge - Process |
The next stages were undertaken by the "hammerman", who in some iron-making areas such as South Yorkshire was also known as the "stringsmith", who heated his iron in a string-furnace. Because the bloom is highly porous, and its open spaces are full of slag, the hammerman's or stringsmith's tasks were to beat (work) the... | Wikipedia - Finery forge - Process |
