Title: Paint color change system
IPC: C09D7/80
Filed: 1988-11-08
Abstract: A paint color change system (10) and method for sequentially 
supplying different color electrically conductive paints to an 
electrostatic applicator (23). paint is supplied through a 
supply hose (31 ) to a first isolated reservoir (21 ) and the supply 
hose (31 ) is purged and dried to form a voltage block. While 
paint is supplied through a first delivery hose (36) from the 
first reservoir (21) to an applicator (23), a second reservoir 
(22) is cleaned, paint is supplied to the second reservoir 
(22) through a supply hose (52), and the supply hose (52) is 
purged of paint and dried to form a voltage block. Upon completion 
of coating with the first color paint, the first delivery hose 
(36) is purged of paint and dried to form a voltage block 
and paint then is supplied from the second reservoir (22) 
through a second delivery hose (57) to the coating applicator 
(23). If the same color paint is applied from both reservoirs 
(21, 22), the first delivery hose (36) can be cleaned and dried 
after paint delivery from the second reservoir (22) has started 
to permit continuous coating.
Patent EP-0318281-A3 (EP)
IPC: C07H21/00
Filed: 1988-11-24
Abstract: dsRNA reduces the phenomenon of viral escape and 
cellular damage attendant thereto. Viral escape is a 
process by which a virus or intracellular pathogen 
alters its host range or indirectly alters its 
susceptibility to antiviral or immunological 
therapies. Viruses do so by causing specific changes 
in their genomic/antigenic composition and/or by 
causing the elaboration of factors which enhance 
destructiveness of cells and their ability to 
multiply progeny virus. Animals susceptible to viral 
infections and pathology secondary to antigenic drift 
may have damage reduced by exposing them to dsRNA 
which prevents or substantially minimizes viral 
escape brought about through these mechanisms of 
molecular rearrangement and/or elaboration of factors 
which break down the natural host defenses.

Title: Injection molding system having a valve member with a ribbed insulative portion
IPC: B29C45/73
Filed: 1989-08-09
Abstract: A valve gated injection molding system having a 
novel valve member for large volume applications. The 
elongated valve member (66) has a ribbed insulative portion (94) 
between the main steel portion (96) and a conductive portion (98) 
adjacent the tip end (80). The conductive portion (98) provides 
more rapid cooling when the tip end (80) is seated in the gate 
in the closed position. The adjacent insulative portion (94) 
provides a thermal barrier to reduce heat flow along the 
valve member to the conductive portion (98). This combination 
avoids sticking of the tip end (80) when the mold opens and 
thus allows cycle time to be reduced. The conductive 
portion (98) has an integral beryllium copper plug (108) which is 
supported by radially extending ribs (102) of the insulative 
portion (94) to withstand continual repeated impact loading 
every time the gate is closed.

Title: Packing small mesh pieces
IPC: B65B63/00
Filed: 1989-10-24
Abstract: It is known to use small, light weight mesh pieces 
having high flexural recovery, to strengthen a matrix. 
Such mesh pieces are very difficult to handle and 
package. In order to provide a suitable packaging 
system, mesh pieces 11 are deposited across the width of 
a moving run of flexible wrapping material 13 and are 
deposited in longitudinally overlapping relationship 
along the length of the wrapping material, by feeding 
the mesh pieces 11 on a belt 10 which moves more quickly 
than the wrapping material 13; the mesh pieces 11 are 
ejected from the end of the belt 10 onto the wrapping 
material 13. The direction of movement of the wrapping 
material 13 is inclined downwards so that the trailing 
ends of the mesh pieces 11 contact the wrapping material 
13 before the leading ends contact the preceding mesh 
piece 11. The wrapping material 13, with the mesh 
pieces 11 on it, is then rolled up under tension into a 
spiral bale so that the overlapping edges curl down and 
prevent the mesh pieces 11 slipping out.

Title: Vortex flow blower and method of manufacturing the same
IPC: F04D23/00
Filed: 1990-02-12
Abstract: The present invention relates to a vortex flow 
blower used as an air source to be incorporated into 
general industrial machines. The vortex flow blower 
according to the present invention is characterized in 
that the shape of the blade (5) in its impeller (1) is three 
dimensionally formed such that at least the inner portion 
of the blade (5) can be adapted to the three dimensional 
internal flow. According to the present invention, the 
aerodynamic performance can be significantly improved and 
the size of a vortex flow blower can be reduced. Furthermore, 
an impeller (1) having three dimensionally shaped blades (5) 
is manufactured by independently manufacturing the shroud (11) 
and the blades (5) and coupling them, so that the impeller (1) of 
a complicated shape can be readily manufactured. 
Furthermore, since the blade (5) can be made of a thin and 
light material, the secondary moment of inertia of the 
impeller can be reduced.
