The equipment turned out to be in poor condition, but by the end of the year Caldwell had repaired it and set up a small office on 53rd Street in Manhattan to take X-rays. [7] This was likely the first X-ray laboratory in the city. [2] Caldwell performed X-rays for physicians on a contract basis. [7]
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
Syl Adrian claims that his brother, Matthew Adrian, invented and built the first machine in Milwaukee; his name is featured in a 1922 advertisement for an X-ray shoe fitter. Clarence Karrer, the son of an X-ray equipment distributor, claims to have built the first unit in 1924 in Milwaukee, but had his idea stolen and patented by one of his ...
He also developed a portable x-ray machine. [7] [14] [18] He also developed an early prototype of a snowmobile. It was a "snow machine" that attached skis to the undercarriage of an airplane fuselage and attached a propeller, and a sound track synchroniser (later selling the patent to RCA).
It was there that Grubbe assembled the first x-ray machine in Chicago in 1896, and that same year, used it to treat a woman with recurrent carcinoma of the breast (disputed). [5] He assembled the machine and began to use it in treatments less than a year after Wilhelm Röntgen announced his discovery of the x-ray. [ 6 ]
The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, a take-up arm, and finally through the hole in the needle. The lower thread is wound onto a bobbin, which is inserted into a case in the lower section of the machine. Walter Hunt invented the first lock-stitch sewing machine in 1833.
