Pittsburgh and Castle Shannon Plane was a narrow gauge incline railway that ran from the northern end of the Pittsburgh and Castle Shannon Tunnel to Carson Street in Pittsburgh, Pennsylvania.
 Originally built to carry coal from the Jacob Beltzhoover mine, it was sold by the Pittsburgh Coal Company to the Pittsburgh and Castle Shannon Railroad in 1871.
 It was used only for coal as early as 1864, passenger traffic was added in 1874 for the Pittsburgh and Castle Shannon Railroad.
 For safety reasons, the tunnel was closed to passenger traffic, and passengers were diverted to the Castle Shannon Incline, constructed in 1890.
 Emergency use of the plane for passengers and freight continued as late as 1900.
 Its use for the transport of passengers and freight other than coal was made obsolete by the Mount Washington Transit Tunnel.
 Operation as a coal incline continued until May 1, 1912.

A stealth startup is a startup company that operates in stealth mode, i.e. that avoids public attention.
 This may be done to hide information from competitors, or — as part of a marketing strategy — to manage public image.
 The phenomenon is well known in the venture capital (VC) community.
 Normally a company would only operate in stealth mode for the first couple of years.
 As investors may have to disclose funding a stealth startup, their names are made public, but often only a general summary description is known about the company.
 "Most entrepreneurs say they are in stealth because they are worried about competitors stealing their ideas.
 This can be a risk if you have such a simple idea that just by hearing it, someone can replicate it."

Poly Implant Prothèse (PIP) was a French company founded in 1991 that produced silicone gel breast implants.
 The company was preemptively liquidated in 2010 following the revelation that they had been illegally manufacturing and selling breast implants made from cheaper industrial-grade silicone since 2001 (instead of the mandated medical-grade silicone they had previously used).
 The hundreds of thousands of unapproved implants sold globally by PIP from 2001 to 2010 were found to have a 500% higher risk of rupturing or leaking than approved models, as well as being implicated in at several deaths due to systemic toxicity and several cases of induced breast cancer.
 The scandal, which produced fears of a massive health disaster, prompted a full recall of the company's implants by the French health ministry in 2010, by which time the company was already defunct.
The Evans Manufacturing Company Building, also known as Metropolitan Supply Company Building, is a historic building located in Cedar Rapids, Iowa, United States.
 The Brown-Evans Manufacturing Company, which made men's work clothing, was relocated from Sedalia, Missouri to Cedar Rapids when this building was completed in 1919.
 It was built in the 4th Street Railroad Corridor, which had attracted various industrial enterprises in the years before and after World War I.
 The Modern Movement building was designed according to the principles of industrial design of the time in light of the Triangle Shirtwaist Factory fire in 1911.
 Its fireproof masonry construction was intended to lessen the risk of fires.
 Storage of raw stock was located in the basement, cutting and storage of finished stock was located on the first floor, and sewing was done on the second floor and balcony.
 Its open floor plan allowed for assembly line production.

 Its stake made up 2.48%.
 RCO itself was in the cleaning, catering and security porterage business.
 In 2000 a company called ISS (UK) Ltd took over RCO, acquiring 96.4% of the shares.
 It made one of RCO's subsidiaries transfer its shares to one of ISS's subsidiaries for £30,117,784.
 Rock Nominee's filed for a petition of unfair prejudice on the grounds that this was a transaction at an undervalue.
 It did not reflect the value to the purchaser of the synergies arising from the sale or the value of avoiding risk from a sale on the open market.
