Title: Particle analyzing apparatus and method for determining nuclear shift index
IPC: G01N15/14
Filed: 1989-09-29
Abstract: A particle suspension is irradiated with a laser beam (12) 
and scattered light from a single particle irradiated in an 
irradiating zone is detected as a plurality of particle 
signals. The laser beam (12) in the irradiating zone is 
formed to be narrower than the diameter of a particle nucleus 
in the direction of particle flow and wider than the diameter 
of the particle in a direction perpendicular to the particle 
flow. The degree of complexity of the particle nucleus is 
determined from high-frequency signal components contained in 
one type of particle signal based on side-scattered light 
(26) from one particle, and the degree of symmetry of the 
particle nucleus is determined from the magnitude of a 
difference between two types of particle signals based on 
side-scattered light (26) from one particle. The degrees of 
complexity and symmetry of the particle nucleus serve as data 
for particle analysis.

Title: Thermal safety valve
IPC: F16K17/38
Filed: 1989-10-14
Abstract: The safety valve has a valve body (6) which is held in its open position by melt material (8). When an excessive rise in temperature takes place, the melt material (8) liquefies and releases the valve body (6). The latter travels, under the action of a spring (7), into a valve seat (5) which is defined by an inlet opening (2) of a shut-off fitting (1) accommodating a shut-off element (4). Between the valve seat (5) and a  complementary inclined surface (14) of the valve body (6) there is produced a heat-resistant metallic seal which, as the temperature increases, is secured against its guide by a thermal prestressing of the valve body (6). <IMAGE>

Title: Manufacture of relief holograms
IPC: B29C35/08
Filed: 1989-02-01
Abstract: A continuous method of manufacturing relief 
holograms, comprises the steps of providing, between 
a transparent web of plastics film and a surface to 
be replicated, a coating of ultra violet curable 
liquid monomer resin, and irradiating the latter by 
ultra violet light directed through the transparent 
web of plastics film to cause the monomer resin to 
crosslink and form a solid matrix which, on one side, 
has taken up the contours of the surface to be 
replicated.  
     Apparatus suitable for carrying out the 
continuous method comprises means for applying to one 
surface of a moving layer of transparent plastics 
film web a coating of ultra violet curable liquid 
monomer resin, a rotary drum (33) mounting on its 
circumferential surface one or more replicatable 
elements (13) against which the resin-coated surface of 
the moving transparent plastics film web is applied, 
and ultra violet light means (35) at least partially 
surrounding the drum to direct ultra violet light 
through the transparent plastics web to effect 
crosslinking of the monomer resin coating to form a 
solid matrix which on the drum side takes up the 
contours of the replicatable elements.

IPC: C22C9/00
Filed: 1989-03-06
Abstract: A circuit system has a semiconductor device mounted on a 
substrate which includes a composite metal material comprising a 
plurality of discrete elements of ferrous metal material such as 
an alloy of 36 percent nickel and the balance iron having a 
relatively low coefficient of thermal expansion, the discrete 
elements being copper-coated by electroless copper plating or the 
like and being pressed together and heated for sintering or 
diffusion-bonding the copper coatings together to form a 
continuous copper matrix having the discrete elements secured in 
dispersed relation therein for providing the composite metal 
material with a coefficient of thermal expansion relatively much 
lower than that of the copper material, the heating of the coated 
particles for diffusion bonding thereof being regulated for 
forming the continuous copper matrix while leaving the copper 
material of the matrix substantially free of nickel, ferrous or 
other constituents diffused therein from the discrete elements for 
providing the composite material with improved thermal 
conductivity.
Patent EP-0333439-A3 (EP)
Title: Centrifugal or rotary pump structure
IPC: F04D29/60
Filed: 1989-03-14
Abstract: The present invention relates to a centrifugal pump structure which allows easy, sturdy, and reliable mounting of the pump on its bed in several different attitudes. Prior art centrifugal pumps or more precisely the casings of the pumps have two support legs by which the pump is mounted on its bed. This allows mounting the pump in a simple way only in one basic position which almost without exception is with the pressure opening upwards. If it has been necessary to mount the pump with the pressure opening facing to the side, the bed of the pump has been provided with a vertical suspension member on which the pump has been suspended with its legs. This kind of a suspension is not, however, rigid, strong, sturdy or reliable as the pipe line forces exert great stresses on the pump shaft, bearings, etc. The above disadvantages have been eliminated by a mounting system of the present invention according to which the legs (7, 17) of the casing are situated at the opposite side of the pump to that of the pressure opening (6) and on both sides of the longitudinal plane passing through the pump shaft (4) and the pressure opening (6); in which the legs (7, 17) have two planar surfaces (27, 37) for mounting of the pump; and in which there are, on both sides of the pressure connection (6) substantially in the longitudinal plane passing through the shaft (4) of the pump, brackets (8) with planar mounting surfaces (18, 28) for mounting the pump.

nant gas. A method to mitigate the effect of an environ­
mental release of a contaminant gas employing the foregoing 
system is likewise embodied herein.

Title: Writing instrument
IPC: B43K24/08
Filed: 1990-02-13
Abstract: Various forms of switching devices for ball-point pens are known, by means of which the insert is received so as to be longitudinally displaceable between a retracted and a writing position inside a shaft (1) with the assistance of a spring. However, the essential feature of the known embodiments is that a plurality of movable construction elements interact within the framework of the switching device. To simplify the assembly, but in particular to reduce the components required in total within the framework of the switching device, a writing instrument according to the invention is proposed, whose switching device consists solely of an insert part (7), arranged fixedly inside the shaft (1), and an actuating device (4) which is arranged movably inside said insert part and constructed integrally with the pusher (3). The actuating device (4) has a component which is intended to engage with the insert part (7), can be deflected elastically and is swivelled into mutually perpendicular planes for engagement or disengagement. The said component, constructed as a switching rod (13), is provided with switching teeth (22, 23) which interact with control cams of the insert part (7). Both construction elements forming the switching device are constructed as plastic injection mouldings which allow smooth switching movements and secure switching positions. <IMAGE>
