Title: Radiant tube burner comprising a catalyst bed for a heat treatment furnace
IPC: C21D1/52
Filed: 1987-09-02
Abstract: The radiant tube burner for furnaces for heat-treating metallic workpieces under the action of a treatment gas generated by catalytic reaction of a feed gas has a shell tube, which has gas outlet orifices at its end, an inner tube which is coaxially arranged in and at a distance from the shell tube and in which at least one burner tube and an air feed tube are arranged, and also a catalyst bed which at least partially fills the interspace between the shell tube and the inner tube. To improve the controllability of the composition of the treatment gas, it is proposed that at least one burner tube of the radiant tube burner is displaceable in the longitudinal direction thereof.
Patent EP-0264025-A3 (EP)
IPC: H01J29/12
Filed: 1987-09-30
Abstract: A laminar flow electron gun (16) for use in a 
light valve of the Schlieren dark field type is 
disclosed. The gun uses three accelerating 
electrodes (111, 112 and 113) with critical axial 
spacing to beam diameter ratios to allow 
independent adjustment and/or modulation of beam 
current density at the imaged aperture while 
reducing criticality of electrode voltages on the 
second and third accelerating electrodes. The 
design permits, but does not require, the use of a 
separate control grid electrode (110). The first 
accelerating electrode (111) is closely spaced to 
the cathode (119) to provide a virtual cathode at, 
or about, the voltage level of that electrode that 
reduces the thermal beam spread normally 
encountered in conventional electron guns. 
Primary control of the narrow angle beam current 
is by adjustment of the beam current density 
impinging on the final aperture (121) in the gun. 
The interaction of negative and positive electron 
lenses within the gun retains laminar flow 
conditions to the final aperture over a wide range 
of beam current levels, assuring low beam spread 
in the output beam from the gun.

Abstract: An apparatus and a method for inspecting cullet (2) for the presence 
of unwanted materials among the pieces of glass. A light source such 
as a laser (11) directs light onto the cullet (2). At least one array 
of at least two light detectors (8) is positioned to delete reflected 
light from the cullet (2). The detectors (8) differentiate between 
non-uniformly scattered light from the cullet (2) and generally 
uniformly scattered light from the debris. Signalling means are 
provided to signal the differentiation thereby to indicate the 
presence of debris in the cullet (2) under inspection. When cullet 
(2) is present on a moving cullet belt (1), light from the light 
source (8) is intermittently scanned over the cullet (2) in a 
raster-type scan. A multi-faceted rotatable mirror (12) may be 
employed intermittently to reflect light onto the cullet (2).

Title: Liquid crystal display devices and their method of manufacture
IPC: G02F1/136
Filed: 1988-12-12
Abstract: A method of manufacturing an active matrix addressed liquid 
crystal display device consisting of an array of individual picture 
elements (10) comprising picture element electrodes (20) on a 
transparent substrate (25) controlled by switching elements (16) 
connected to at least one set of parallel address conductors 
(12, 14) of opaque material formed on the substrate involves 
forming the electrodes (20) after the address conductors by an 
autoregistration process using the address conductors to define

aligned with respective facing edges of adjacent address conductors 
of the one set or, in the case of crossing row and column conductor 
sets being provided on the substrate, both sets. The device's 
active area is thereby maximised and uncontrolled areas minimised.

Patent EP-0374882-A3 (EP)
Title: A hot standby transmitter switching system
IPC: H03C1/60
Filed: 1989-12-20
Abstract: In a hot standby transmitter system, each identical 
transmitters, one of which is a primary and another one is 
a standby, comprises an image-cancel type mixer (41, 51), which 
outputs upper or lower sideband waves of a local frequency, 
according to its internal connection controlled by a switch 
controller (3). The switch controller (3) controls the internal 
switches (416, 516) and an RF switch (6), so that the primary transmitter 
outputs a predetermined primary one of the sidebands and 
the standby transmitter outputs another sideband, and the 
RF switch (6) selectively connects the output of the primary 
transmitter to outside. The standby transmitter 
undesirably outputs a small level of the primary sideband 
though it should be theorectically zero. This low level 
primary wave component in the standby transmitter's output 
allows a reduction in the isolation amount of the RF 
switch (6), compared with high isolation amount required in a 
prior art method where the standby transmitter outputs the 
primary wave in as high as the primary transmitter level, 
in order to keep the ratio of power level from the primary 
transmitter to the power level from the standby transmitter 
higher than a predetermined requirement level. The circuit 
to detect a fall in the output power is simple compared 
with a complex circuit required in another prior art method 
where the standby transmitter outputs the less primary wave 
than the primary transmitter.

Title: Apparatus for detecting the presence of moisture as a result of leakage
IPC: G01M3/22
Filed: 1989-08-14
Abstract: Moisture detection apparatus for detecting the 
presence of water leaks from water cooled panels in an 
electric arc furnace comprises one or more moisture 
sampling members (10) mounted on the furnace shell at 
locations below the bottoms of the water cooled panels. 
Each member (10) comprises a sampling tube (36) extending 
through a bore (30) into the furnace lining and an air 
intake (38) external of the furnace shell communicating 
with the sampling tube (36). An extractor pump sucks air 
through the intake (38) and sampling tube (36), thus 
picking up any moisture which is present below the water 
cooled panel (26), to cause the air to flow through an 
associated moisture sensor. The apparatus includes 
signal means responsive to a predetermined maximum 
permissible moisture content sensed by a sensor. The 
signal means may provide a visual and/or audible signal 
and/or a signal to actuate an air flow control valve to 
prevent further intake of air through the associated 
sensor.

Title: Downhole tool and method for determination of formation properties
IPC: E21B49/08
Filed: 1989-09-14
Abstract: The apparatus of the present invention relates to a down 
hole tool (A) capable of extraction of valid samples and making 
pressure measurements useful in calculating formation 
permeability. The tool incorporates the features of a straddle 
packer (P) to allow formation fluid specimens to be taken at large 
flow rates without depressing the pressure below the formation 
fluid bubble point. When used in combination with a pressure 
probe (46) the tool is used to obtain meaningful permeability readings 
in a larger radius area than previously permitted with known 
designs. Additionally, the apparatus of the present invention 
allows flow control during the creation of the pressure pulse 
which enhances extraction of valid samples and the permeability 
determination. The apparatus may be modularly constructed so 
that in a single descent of the tool, a pressure profile of the 
zone of interest can be made, a fluid analysis can be made at 
each station, multiple uncontaminated fluid samples can be 
withdrawn at pressures above the bubble point, local vertical and 
horizontal permeability measurements can be made at each station, 
a packer module can be set at a location dictated by previous 
measurements and a large scale pressure build up test can be 
performed.
