Title: Method and apparatus for controlling steam in a pellet mill
IPC: F22B1/26
Filed: 1988-06-28
Abstract: A control (54) for a vapor steam generator (42) 
as used with a pellet mill (20) senses the exhaust 
temperature of the steam and controls it by modulating 
the flow of air/gas to the burner independently of the 
flow rate of moisture such that steam having a constant 
moisture content can be produced at varying 
temperatures. The constant moisture content steam is 
desirably used in the pellet mill by ratioing the flow 
of moisture to the flow of dry material such that 
finished pellets having a pre-determined moisture 
content can be reliably produced.

Title: Preobjective scanning system
IPC: G03G15/04
Filed: 1989-04-28
Abstract: A preobjective scanning optical system for use 
with a rotating mirror scanner employing LEDs or lasers 
to electronically reproduce photographs. The optical 
system includes a doublet disposed before the mirror and 
a triplet disposed after the mirror. Instead of 
collimating, the first optical system along with the 
mirror forms a virtual, curved image of the LEDs or 
lasers as the scanner rotates and includes a first and a 
second lens which, in combination, correct the image for 
on-axis spherical and axial color aberrations. The 
triplet has net positive power and its three lenses, in 
combination, correct for off-axis aberrations such as 
astigmatism, coma, and lateral color aberration but can 
be under corrected for field curvature because its 
object is the curved virtual image.
