Richard L Maughan, Gabe F Blosser, Emanuel B Jemison, Henry G Blosser: Variable radiation collimator. Michigan State University, Ian C McLeod, June 28, 1988: US04754147 (60 worldwide citation)

A variable collimator 10 for shaping the cross-section of the beam 100 is described. The collimator relies upon rods 16 which are positioned around the beam axis a-a with the rod 16 axis b-b perpendicular to the beam axis. The rods are shaped by shaping member 24 which is cut to the shape of an area ...

Henry G Blosser, Richard J Burleigh, Gabe F Blosser, Emanuel B Jemison: Superconducting medical cyclotron. Board of Trustees operating Michigan State University, Ian C McLeod, February 3, 1987: US04641104 (53 worldwide citation)

An improved superconducting cyclotron (10) particularly useful for medical or therapeutic purposes is described. The vessel (105) for liquified gas surrounding superconducting coils (101, 101a) is provided with a capillary tube (200) joined to a semi-circular tube (123) leading into an exit tube (20 ...

Henry G Blosser, Bruce F Milton: Superconducting synchrocyclotron. Board of Trustees operating Michigan State University, Ian C McLeod, February 3, 1987: US04641057 (50 worldwide citation)

A synchrocyclotron with superconducting coils (1) is described. The coils are provided in a vessel (4) which is supported by low heat leak members (6) in a cryostat (7). A liquified gas (helium) is provided in the vessel to cool the coils so as to render them superconducting.

A collimator apparatus (10 or 100) including one or more bundles of nested rods (11, 11a or 101 or 101a or 201) which define a surface (112, 112a) which interferes with a beam of radiation is described. The apparatus particularly uses coil spring (48) between and along the axis (a--a or c--c) of the ...

Henry G Blosser, David A Johnson, Jack Riedel, Richard J Burleigh: Rotatable superconducting cyclotron adapted for medical use. Board of Trustees operating Michigan State University, Ian C McLeod, March 26, 1985: US04507616 (43 worldwide citation)

A superconducting cyclotron (10) rotatable on a support structure (11) in an arc of about 180.degree. around a pivot axis (A--A) and particularly adapted for medical use is described. The rotatable support structure (13, 15) is balanced by being counterweighted (14) so as to allow rotation of the cy ...

Henry G Blosser, Gabe F Blosser, Emanuel B Jemison, John R Purcell: Vented 360 degree rotatable vessel for containing liquids. Board of Trustees Operating Michigan State University, Ian C McLeod, December 30, 1986: US04633125 (37 worldwide citation)

An apparatus 10 including a valveless rotatable, continuously vented vessel 11 for containing a liquid is described. The vessel can be confined in a vacuum chamber 15 to reduce heat losses from the liquid in the vessel. The apparatus is particularly adapted for containing superconducting coils in a ...
