Patent EP-0395816-A3 (EP)
Title: Die cutters
IPC: B26F1/08
Filed: 1989-11-08
Abstract: A die cutting press and a method of die 
cutting include two opposing and oppositely driven 
clamping bars (22,24) which move together to clamp 
the die board (14) and accurately position the 
clamped die board (14) at a predetermined location 
within the press. The press is operated to determine 
the adequacy of the cut produced by the die (15) in 
sheet material fed into the press. If the cut is 
unsatisfactory, the opposing clamp bars (22,24) are 
quickly driven apart thereby releasing the die 
board (14). The die board (14) can be removed from 
the press and then manipulated or modified to cure 
any imperfection in the cut. The modified die 
board (14) is then reinserted into the press and 
accurately repositioned at the predetermined location 
within the press by driving the opposing clamping 
bars (22,24) towards each other against the die 
board (14). The drive mechanism (21,23) of the 
clamping bars (22,24) ensures that when the die 
board (14) is securely clamped, the die board (14) 
will always be accurately repositioned in the same 
press at exactly the location assumed by the die 
board (14) when it was inserted. The opposing moving 
clamps (22,24) automatically move the die board (14) 
to the predetermined position without the need for 
measurement, registration or concern for variations 
in tolerances within a jig.
Patent EP-0371777-A3 (EP)
Title: Magnetic disk drive
IPC: H02P25/06
Filed: 1989-11-29
Abstract: A magnetic disk drive is provided which releases 
adhesion between a magnetic head (51) and a magnetic disk (50) by 
radially moving the head before the disk begins to 
rotate. The head movement is accomplished by compressing an 
elastic stopper (52b) by driving a head actuator motor (53) 
with drive current caused to flow at half of the 
voltage previously applied to a motor drive circuit (PA) by 
grounding one terminal of the motor (53) and forcing all of 
the motor drive transistors OFF except for one 
transistor in the motor drive circuit (PA), with the benefit 
that smaller and cheaper transistors can be used, and 
in addition power consumption is considerably reduced, 
thus contributing to a smaller, cheaper drive circuit 
which consumes less power.
Patent EP-0347298-A3 (EP)
Title: Method and device for the measurement of visibility through a medium of varying opacity
IPC: G01N21/53
Filed: 1989-06-12
Abstract: The invention relates to a method and a device for measuring visibility through a diffusing medium of variable opacity, for example fog. This method is characterised in that the back scattering is measured in the direction (7) included within the range of angles along which, for the wavelength ( lambda ) specific to the light which is emitted, there is a tendency towards coincidence of all the curves of variation of the phase functions as a function of the angle ( theta ) between the emission direction and the back scattering direction, each specific to a fog of particle size different from that of the other curves. This method permits the use of an ad hoc device to obtain a measurement of the visibility of the fog, which measurement is independent of the particle size of that fog. <IMAGE>
Patent EP-0368808-A3 (EP)
Title: Immobilized enzyme and a method for application thereof
IPC: C12P19/34
Filed: 1989-11-03
Abstract: Porous chitosan beads are used as carriers for immobilization of 
polynucleotide phosphorylase (PNPase). Immobilization of PNPase to the 
porous chitosan bead carrier can be effected by contacting the enzyme 
with the carrier in water or in a buffer solution such as phosphate or 
borate buffer solution, preferably at room temperature. The thus 
obtained immobilized enzyme is contacted with a solution of nucleoside, 
e.g. cytidine-5′-diphosphate or inosine-5′-diphosphate, to 
produce the corresponding polynucleotide, e.g. poly C or poly I. The 
yield of polynucleotide is thus improved and the costs reduced. Also, 
the reaction can be conducted by a continuous process and the chain 
length of the polynucleotide can be controlled.

Title: A valve for protecting ventilation openings of closed environments from explosion waves
IPC: F16K17/00
Filed: 1989-04-05
Abstract: There is described herein a valve for protecting a 
ventilating opening of a closed environment in general, 
against explosion-generated waves.  
     Therefore, the subject valve is used in the construction 
of both military and civil shelters, in military 
vehicles and vessels, in the field of civil and 
industrial protection, in order to obtain a ready 
protection in particular for ventilating suction ports 
connected to the outside, and for protecting air eject­
ion openings from air conditioned environments, and in 
general all those openings through which air or gas in 
general is drawn or ejected.  
     To meet the above objective the inventive valve uses at 
least a pair of thin plates (10), resiliently deformable 
under the action of the above waves and adapted to dampen 
said waves in both cases where they are overpressure 
waves or vacuum waves, thereby protecting the opening 
where the valve is mounted.

Title: Fuel pressure regulator valve
IPC: F02M69/00
Filed: 1990-04-02
Abstract: A fuel pressure regulator valve (10) of the type commonly 
used in automobile fuel injection systems. The invention 
relates to improved retention of the valve element within 
the mount that is carried by the diaphragm assembly (14). The 
valve element is a truncated sphere (32) and the retention is 
by means of a circular washer (36) that fits into a circular 
recess formed in the mount (28) around the cavity that contains 
the sphere. The truncated circular face of the sphere 
protrudes through the washer (36) so that it can coact with the 
valve seat (24). The inside diameter of the washer (36) is closely 
controlled and this controls the allowable travel of the
