Abstract: An electrostatographic duplicator in which an original document 
is duplicated by redeveloping a previously developed and fixed 
latent image has a rotatory drum 4 for supporting a sheet of 
electrostatographic recording material releasably clamped thereon. A 
supply spool 1 carries electrophotographic recording material in web 
form, and rollers 2 advance the recording material towards the drum 
4, after which guillotine 3 cuts an individual sheet of 
predetermined length from the advancing web. The individual sheet is 
directed by rollers 2 onto the support member and clamped thereon. A 
corona charging unit 12 electrically charges the recording material 
on the support member, an imaging station 11, 25 projects a light 
image of the original document onto the recording material, a 
development station 7 applies an insulating toner to an 
electrostatic latent image on the recording material and a master 
fixing unit 14 fixes the developed toner image onto the sheet of 
recording material supported on the drum 4. In duplicating cycles 
means 16, 17 feeds copy sheets serially towards the support member, 
a transfer station is located so that copy sheets pass between an 
electrically charged transfer member 9 and the recording material on 
the drum 4 so that an unfixed toner image transfers onto a copy 
sheet. The copy sheets pass to a copy sheet fixing device 5 and the 
recording material travels past a cleaning unit 20 before it is 
re-charged at corona unit 12 and flood exposed at a station 20 in 
the next duplicating cycle, control means responsive to a start 
button and a counter records the number of duplicated copies 
required and controls the operation of all the aforesaid devices so 
that (I) in a master preparation cycle a sheet of recording material 
is cut from the material on the supply spool 1 and clamped onto the 
drum 4 after which a fixed toner image is formed on the master by 
driving the drum 4 at a first speed, electrically charging the 
recording material, forming a latent image of the original document 
thereon, developing 7 the latent image with toner and radiant heat 
fusing the developed toner image onto the recording material, (II) 
in subsequent duplicating cycles the drum 4 is driven at a second 
speed higher than the first speed and cyclically the drum is cleaned 
(20), electrically charged (12), uniformly illuminated (15) and 
redeveloped with toner (7) and the resulting toner image is 
transferred onto copy sheets and fixed thereon, and (III) on 
completion of duplication the used sheet of recording material is 
ejected from the support member.

Filed: 1984-10-10
Abstract: The filter according to the present invention has mini­
mum dimensions, because the centers of cavities are 
foreseen in the apexes of a broken line, whose sides form 
among themselves angles greater than 90°.  
     The filter body is preferably realized by pressure die-­
casting of an aluminium alloy having an high flowability in 
the dies: the dilatation coefficient of the cavities is compen­
sated using, in the resonators and syntony screws, some 
materials different from the one of the filter body. The 
electric losses are minimized by differential ratios among the 
diameters of cavities (Dc) and of the relevant resonators. The 
weight is optimized by lightenings got by cavities realized in 
the body.
