Q: Work commenced on 9 July 1944, and S-50 began partial operation in September. Ferguson operated the plant through a subsidiary known as Fercleve. The plant produced just of 0.852% uranium-235 in October. Leaks limited production and forced shutdowns over the next few months, but in June 1945 it produced . By March 1945, all 21 production racks were operating. Initially the output of S-50 was fed into Y-12, but starting in March 1945 all three enrichment processes were run in series. S-50 became the first stage, enriching from 0.71% to 0.89%. This material was fed into the gaseous diffusion process in the K-25 plant, which produced a product enriched to about 23%. This was, in turn, fed into Y-12, which boosted it to about 89%, sufficient for nuclear weapons.
How many months after Work commenced did they start operations on the s-50?

Q: Hoping to rebound from their road loss to the Bengals, the Panthers returned home for a Sunday night match-up with the Dallas Cowboys. In the first quarter, Carolina started off strong with a 1-yard TD run by DeShaun Foster. The Panthers would even have QB Jake Delhomme complete a 24-yard TD pass to WR (Steve Smith). In the second quarter, the Cowboys started to play catch-up. QB Tony Romo completed a 3-yard TD pass to TE Jason Witten and kicker Mike Vanderjagt would complete a 38-yard field goal.

Q: Following a tough road loss against the Bears, the Steelers flew to Paul Brown Stadium for a Week 3 AFC North duel with the Cincinnati Bengals. Pittsburgh would strike first in the first quarter with kicker Jeff Reed's 19-yard field goal and quarterback Ben Roethlisberger's 27-yard touchdown pass to running back Willie Parker. The Steelers would add onto their lead in the second quarter as Reed made a 34-yard field goal. The Bengals would close out the half with kicker Shayne Graham's 34-yard field goal. Cincinnati would creep closer in the third quarter as cornerback Johnathan Joseph returned an interception 30yards for a touchdown (with a failed PAT), yet Pittsburgh answered with Roethlisberger's 1-yard touchdown run. However, in the fourth quarter, the Bengals took the lead with running back Cedric Benson's 23-yard touchdown run (with a failed 2-point conversion) and quarterback Carson Palmer's 4-yard touchdown pass to wide receiver Andre Caldwell (with a successful 2-point conversion pass to running back Brian Leonard). The Steelers tried to rally, but Roethlisberger's last-second hail mary pass was incomplete, preserving the defeat. With the loss, Pittsburgh fell to 1-2 and 3rd place in the AFC North. This would also become the team's first 1-2 start since 2006. Wide receiver Hines Ward (4 receptions, 82yards) would become the 21st player in NFL history to surpass 800 career receptions and 10,000 receiving yards.

Q: Greenleaf expanded and upgraded the Conn plant, and converted distribution from mail-order to retail dealers. By 1917 the assembly-line work force had increased to 550 employees who were turning out about 2500 instruments a month using a new hydraulic expansion process which Greenleaf introduced to the plant. In 1917 Conn introduced the Pan American brand for its second-line instruments. Conn founded the subsidiary Pan American Band Instrument Company in 1919 and later that year moved production of second-line instruments to the old Angledile Scale factory. In 1930 the Pan American company was absorbed by Conn, but the Pan American brand for Conns second-line instruments remained in use until 1955. Conn founded the Continental Music retail subsidiary in 1923. At its height, the operation included a chain of over 30 music stores. During the 1920s Conn owned the Elkhart Band Instrument Company (192327), the Leedy Company (192755), a manufacturer of percussion, and 49.9% of the stock of the retailer Selmer Company (192327). Conn purchased the drum manufacturer Ludwig Drums, the instrument import/retail operation of the Carl Fischer Music company, and accordion manufacturer Soprani in 1929. From 1940 to 1950 they owned the Haddorff Piano Company, and from 1941 to 1942 the Straube Piano Company.
