Letter to William Collver or John Roberts, 1849

A letter to “my dear Mr. Collver and co.” The writer mentions the “circuit” that she has traveled, and a conference which she attended. In regard to the circuit, she talks about her interest in the Welland Canal. The references all seem to be religious in nature. She asks Mr. Collver how he likes the new preacher and says that in a letter that the preacher published in the newspaper he refers to the “breaking of Jordan Chapel”. She says that a society of teetotalers has been established in her town and they are known as “Sons of Temperance”. She also mentions “my man Brown” who was there but has left, leaving her to have the circuit by herself. She signs off with “I am yours affectionately [Eleanor Corman]. The second part of the letter is addressed to “my dear Mr. Roberts”. She asks him for some music that she would like, but cannot find in Kingston. She would like him to “come down and teach singing” this winter. She also asks him to give her regards to Mr. P. Beamer and family. She ends this part of the letter with “Nothing further yours affectionately [Eleanor Corman]”. There are 4 red postmarks on the outside of the letter and they are: Picton, July 31, 1849 Cobourg, August 2, 1849 St. Catharines, August 4, 1849 There is one other postmark which is too faded to be legible.

Deposition of hydroxyapatite and calcium oxalate dihydrate on a heat exchanger tube

Most studies on the characterisation of deposits on heat exchangers have been based on bulk analysis, neglecting the fine structural features and the compositional profiles of layered deposits. Attempts have been made to fully characterise a fouled stainless steel tube obtained from a quintuple Roberts evaporator of a sugar factory using X-ray diffraction and scanning electron microscopy techniques. The deposit contains three layers at the bottom of the tube and two layers on the other sections and is composed of hydroxyapatite, calcium oxalate dihydrate and an amorphous material. The proportions of these phases varied along the tube height. Energy-dispersive spectroscopy and XRD analysis on the surfaces of the outermost and innermost layers showed that hydroxyapatite was the major phase attached to the tube wall, while calcium oxalate dihydrate (with pits and voids) was the major phase on the juice side. Elemental mapping of the cross-sections of the deposit revealed the presence of a mineral, Si-Mg-Al-Fe-O, which is probably a silicate mineral. Reasons for the defects in the oxalate crystal surfaces, the differences in the crystal size distribution from bottom to the top of the tube and the composite fouling process have been postulated.
