Title: Pigmentary ceramic substrates bearing metal dots
IPC: C09C3/06
Filed: 1988-10-14
Abstract: A pigment of this invention comprises a 
ceramic scaly substrate(1), and metal dots(3) or alloy 
dots(3) formed on the surfaces of ceramic scaly 
substrate(1) in the ratio of from 0.05 to 95 % of the 
total surface area of ceramic scaly substrate(1). An 
inorganic compound coating film(2) may further be formed 
on all over the surfaces of ceramic scaly substrate(1), 
and metal dots(3) or alloy dots(3) may be formed on the 
surfaces of inorganic compound coating film(2) instead 
of on the surfaces of ceramic scaly substrate(1) in the 
same ratio. Thus, this pigment gives various hues with 
metallic gloss feelings due to combined effect of light 
reflection and light scattering with metal dots(3) or 
alloy dots(3) and even light interference with two pairs 
of reflecting surfaces when the inorganic compound 
coating film(2) is employed.

Title: Magnetron tuning systems
IPC: H01J23/20
Filed: 1989-10-24
Abstract: A magnetron (1) is tuned by a co-axial transmission line (21) 
co-axial with the axis of the magnetron and a radial 
transmission line (19) linking the co-axial line to a plurality 
of sampling points (16) symmetrically positioned on the end of

Patent EP-0389097-A3 (EP)
Title: Photonic local/metropolitan area network
IPC: H04B10/275
Filed: 1990-02-14
Abstract: This invention is directed toward providing higher speed local and/or 
metropolitan area optical networks by 
storing light in the fiber of an optical network 
to resolve collisions between advancing packets.  
     One condition that needs to be resolved in packet-switched networks 
occurs when two packets attempt to exit 
a switching node (100,102,104,106) on the same output link. 
With this invention, collisions of optical 
packets are resolved by coupling all packets 
that cannot be forwarded onto the reverse 
links for transmission to the node they 
came from. With this invention, each branch 
of a network, for example, a star type 
of network, is provided with an optical 
fiber path (108,110,112) having two parallel opposite-­
directed, optical links which can be 
selectively configured to form either a direct 
straight throughput or a loop-back path.  
     Prior to advancing a packet to the 
next occurring path, a test is made to 
determine if it is occupied with a packet. 
If it is not occupied, the packet is advanced 
along the forward optical link to the next 
node. If it is occupied, then the two optical 
links of the optical path directed to the 
previous node are very rapidly configured to 
form a loop-back path, and the packet is 
sent around the loop-back path, again and 
again, as required, until the path to the next node is cleared.

having a pivot mounted arm (11) which mounts an elongate 
support member (10). The support member (10) is of arcuate 
shape and has an extensible part (15) adapted to mount a 
probe. In use the retractable part (15) and the probe is 
retracted into an outer part of the support member (10) and 
moved through an arcuate path ('P') by the rotation of the 
arm (11) to be inserted into the vessel (1) through an 
opening (5) in the top. The probe is extended, a sample 
taken, and the probe retracted followed by displacement of 
the support member out of the vessel (1) along path ('P').  
     Because the support member is arcuate, is 
displaced through an arcuate path, and has an extensible 
part, the problem of providing space for the apparatus is 
alleviated.

This is achieved by every connecting piece being a connecting nozzle 16, over which the assigned lower filter disc sector 19 with the outlet orifice 17 is pushed along a drop distance, by the drop distance being adapted to the distance 25 between the lower filter disc sector 19 and the shaft 3 and by a ring segment 26 being pushed by means of a rotary movement about the shaft 3 between the shaft 3 and the lower filter disc sector 19. The lower filter disc sectors are pushed onto the connecting nozzles and the ring segments are pushed under the shaft. <IMAGE>

Title: Raw gas burner and process for burning oxygenic constituents in process gas
Inventor: RUEHL ANDREAS
IPC: F23D14/00
Filed: 1995-12-15
Abstract: Raw gas burner (1) that maximizes fuel efficiency of the burner, minimizes residence time and reduces or eliminates flame contact with the process air or gas in order to minimize NOx formation. Process air flow, such as from the cold side of a heat exchanger associated with thermal oxidizer apparatus (100), is directed into and around the burner. The amount of process air flowing into the burner is regulated based upon the pressure drop created by the burner assembly. The pressure drop is, in turn, regulated by one or more of an external damper assembly, an internal damper assembly, and movement of the burner relative to the apparatus in which it is mounted. To ensure thorough mixing of the fuel and process air, process air entering the burner is caused to spin by the use of a swirl generator (10). The fuel/process air mixture proceeds into the combustion section (50) of the burner, where the swirling flow is caused to recirculate to ensure complete combustion of the fuel in the combustion chamber. The mixture of burned fuel and process gas transfers its energy flamelessly to the process gas circulating outside the burner combustion chamber, and is hot enough to ignite the process gas there, which then burns separately from the burner combustion chamber, such as in the main combustion enclosure (114) of the thermal post-combustion device.
