Patent EP-0319180-A3 (EP)
IPC: G01N21/84
Filed: 1988-11-21
Abstract: An improved mechanism for coordinating the tran­
sport of a glass container through an inspection 
zone with the movement of an inspection head rela­
tive to the container. In a plug gager, a carriage 
(16) which holds the plug gage (13) is moved in the 
direction of container travel by a cam (90), while 
an eccentrically-mounted bearing moves the plug gage 
vertically to penetrate the container finish. The 
invention provides an improved cam profile (95) to 
provide an increased maximum stroke (amount of gage 
penetration) making the apparatus adaptable to a 
wider range of container sizes. Relative to prior 
art cams for apparatus of this type, the constant 
velocity segment of the cam motion is extended. A 
similar adaptation to a leak detector utilizing this 
cam-driven carriage and inspection head arrangement 
lengthens the segment of each cycle during which 
inspection occurs, increasing the sensitivity of the 
system. In a check detector utilizing this arrange­
ment, this improved cam-driven mechanism provides 
increased inspection speed and accuracy, and allows 
better stopping of containers at high speeds.

Title: Optical distribution of analog and digital signals using optical modulators with complementary outputs
IPC: H04B10/04
Filed: 1990-06-16
Abstract: A novel optical system is taught including an optical source, an optical modulator having at least one optical input port for receiving the optical signal from the optical source, a modulation port for receiving the optical signal from the optical source, a modulation port for receiving a modulating signal, and complementary output port signals. The complementary modulated output signals are applied to one or more optical receivers at the other end of an optical transmission link. In one embodiment, the two complementary signals are provided to two separate optical receivers, thereby allowing distribution of optically modulated signals, for example, in a cable television or other type distribution system. In another embodiment, the two complementary modulated signals are applied to a single balanced receiver, thereby providing information content to the complementary receiver twice the power level available on either one channel alone. Furthermore, utilizing a balanced receiver, common mode error signals cancel, thereby increasing the signal to noise ratio of the system. In one embodiment of this invention, a single optical transmission channel is used, and the two optically modulated signals are separated in polarization so as to be capable of being separately detected on the receiving end of the link. In one embodiment feedback means is used to insure proper polarization states for the two complementary signals.

Patent EP-0389294-A3 (EP)
IPC: A23K10/32
Filed: 1990-03-23
Abstract: A method for conversion of comminuted cellulosic 
agricultural wastes into a form edible by ruminant animals 
comprises treating such wastes, e.g., straw, corn husks, 
cotton wastes, peanut shells, saw dust, etc. by spraying with 
an aqueous solution of a mixed oxidant gas, at a pH of about 
11 - 12, to produce a water content of less than 40% and a pH 
of about 11.4 - 11.7 in the waste. The mixed-oxidant gas is 
preferably produced by a gas generator comprising an electro­
lytic cell having an anode compartment, a cathode compartment 
and a membrane separating the compartments to permit only a 
limited flow of electrolyte therebetween. When a low salt 
concentration solution is electrolyzed in this cell, the 
output is a mixed oxidant gas containing chlorine and various 
oxygen-containing species. Another gas generator which may 
be used is that shown in U.S. Pat. No. 4,248,681. The oxidant 
gas produced from dilute salt solutions contains chlorine, 
chlorine dioxide and other oxygen-containing gases. After a 
reaction time from several hours up to several days, the 
product obtained is essentially free from chemically combined 
lignins and has been substantially hydrolyzed to sugars, and 
is a satisfactory feed for ruminant animals. Alternatively, 
the wastes may be treated with aqueous caustic to the desired 
pH and water content and the mixed oxidant gas circulated 
through the waste and absorbed therein.
