Patent EP-0123887-A3 (EP)
IPC: B23C5/20
Filed: 1984-03-23
Abstract: The cutting insert 4 of a sectional milling cutter is fixed 
between two surfaces respectively of the support 2 and the 
fixing bracket, by means of a socket head screw 13. So as 
to position insert 4 rapidly and precisely, with constant 
cutting profile, the face 2′ of the support is equipped with two 
surface plates 8 and 8′ which project and converge together 
at an angle of approx. 75°. In correspondence, the cutting 
insert 4 has seats or apertures 6 and 6′, forming a wedge 
which has an aperture angle equal to that of the planes 8 
and 8′ so that they can be coupled perfectly.  
     The cutting insert 4 has an elliptical profile with two 
cutting surfaces 5 and 5′ and with two apertures or seats 6 
and 6′ which are placed opposite each other and are 
superimposed by rotating the insert around the two respec­
tive transverse axes.  
     On the apex of one of the two apertures 6 acts and 
presses the extremity 9′ of the arc surface 9 which delimits 
the surface plate 2′ and which extends parallel to the cutting 
surface 5 or 5′.

IPC: G09F11/02
Filed: 1984-11-17
Abstract: The mechanism resets to zero the visible digits on a 
series of cylinders aligned on an axle, without inserting any 
friction when the reset is not active. Pressing a knob dis­
places the axle axially causing a series of teeth stamped on 
the cylinder axle to penetrate in respective housings in the 
cylinders. Turning the knob then causes each tooth to en­
gage a corresponding projection within the housing driving 
the cylinders towards zero; simultaneously, the cylinders 
act against their coupling pinions to push the pinion axle 
away and free the cylinders. To avoid free rotation of the pi­
nions so that they may properly reengage the cylinders 
when returning to their normal position urged by springs, 
the pinions are jammed by windows cut out in the cover 
when pushed away. Releasing the knob permits another 
spring to exit the teeth from their housing, so that the cylin­
ders may yet again be driven via the pinions.

Filed: 1984-12-07
Abstract: A method of promoting the more rapid growth of an 
animal or plant, which comprises administering to said 
animal, to a food source for said animal, to a plant or to a 
plant habitat a growth-promoting effective amount of a 
protease inhibitor such as leupeptin. The protease inhibitor 
can be incorporated into an animal feed or supplement 
containing a food base. It apparently functions by inhibiting 
proteases which degrade proteins, and thus reduce the 
growth of the host.

Abstract: An eye movement detection scheme is provided whereby 
both a subject's eye movements and the scene being viewed 
can be monitored simultaneously with compact, light, unob­
trusive yet effective equipment. Scene-mounting as well as 
eye-movement-monitoring devices (19, 13) are mounted on a 
spectacle frame (1) worn by the subject. Signals from these 
devices are conveyed electrically and/or optically from these 
frame-mounted devices to circuitry (23) for generating video 
compatible signals so that the eye movements can be 
superimposed over the scene for purposes of observation and 
analysis. An additional advantage is a feature which facilitates 
use of corrective lenses suitable to the individual subject so 
that eye-glass wearers can use the equipment as well.

Patent EP-0193821-A3 (EP)
IPC: G01N21/72
Filed: 1986-02-22
Abstract: An apparatus and method for measuring the constituent 
elements of a liquid, electrically conductive material includes a 
probe mechanism, which delimits a sampling chamber having 
a spark electrode in communication therewith and which is 
adapted to contain a non-reactive gas. An entry mechanism in­
troduces an aliquot of the conductive liquid into the sampling 
chamber, and a gap reference mechanism detects a reference 
gap distance between a free surface of the liquid aliquot and 
the spark electrode. A gap setting mechanism selectively 
changes the reference gap to a selected spark gap distance 
between the liquid free surface and the electrode. A spark 
generator means sparks an electrical discharge or arc be­
tween the electrode and the aliquot of liquid material to pro­
duce an aerosol sample within the sampling chamber com­
posed of particles of the conductive material within the gas. A 
flow control meachnism controls a flow of the gas in the region 
of the electric arc to provide a flow velocity which is sufficient 
to sweep the aerosol particles away from the liquid aliquot. A 
fluid transport mechanism then moves the aerosol sample 
from said sampling chamber to remotely located analyzer, 
wherein the aerosol sample is analyzed to measure the consti­
tuent elements of the material.

IPC: G01N27/409
Filed: 1987-08-25
Abstract: During the measurement of oxygen content of a gas with a 
solid electrolyte material capable of oxygen ion 
conductivity the electrolyte is heated to maintain a 
constant control temperature. If the ambient temperature 
changes, an offset or error is introduced into the oxygen 
measurement. An apparatus and method is provided to 
automatically compensate for any such offset. 
Thermocouple means are provided in series with the 
electrolyte circuit so that a thermal emf is generated 
due to any differential between ambient and control 
temperatures. The thermocouples are arranged to generate 
a net thermal emf which opposes the emf generated by the 
electrolyte by an amount which automatically compensates 
for any offset due to the temperature differential. If 
the ambient and control temperatures are the same, there 
will be no offset and no net thermal emf.
