Abstract: 1,265,362. Hybrid computers. MULLARD Ltd. 4 Feb., 1969, No. 5833/69. Heading G4G. In a machine in which a beam of charged particles e.g. electrons is accelerated to impinge on a workpiece for etching, welding, cutting or drilling and the beam deflection is controlled from a computer store; correction of deflectional sensitivity is necessary in response to E.H.T. voltage, working distance and focusing field variation and (Fig. 3) a reference voltage R 1  and digital co-ordinate signal L<SP>1</SP> from a control store are fed to a D/A multiplier 21 of the kind incorporating selectively switchable series potentiometric resistors (Figs. 1, 2, not shown) energized from a reference voltage to develop an output analogue signal R1.L which is scale multiplied at 24 by factor A and added at 25 to a further reference voltage R 2  representing the origin co-ordinate of the beam to produce analogue signal R 1 LA + R 2 . This is applied to a further similar D/A multiplier 27 receiving a digital signal M<SP>1</SP> compensating for E.H.T. values from the control store to produce analogue voltage of M. (A.L.R 1  + R 2 ) applicable for electron beam deflection from the R 2  determined origin. The compensating signal M<SP>1</SP> may additionally be made inversely dependent on target distance and corrected for interaction of focusing field and deflection. In a further modification (Fig. 4) a reference signal R is applied to switched potentiometer circuit 33 of a D/A multiplier 31 also receiving from control computer a binary digital deflection sensitivity compensating signal M<SP>1</SP> dependent on E.H.T. voltage and containing correction for focusing field intersection with deflection to produce analogue signal RM applied to D/A switched potentiometer multiplier 41 receiving binary digital deflection sensitivity compensating signal N<SP>1</SP> from control computer inversely proportional to workpiece distance, to produce analogue signal RMN representing deflection sensitivity compensation. This is applied to D/A multipliers 51, 61, 71, 81 receiving binary digital signals L<SP>1</SP> x , P<SP>1</SP>x<SP>,</SP> L<SP>1</SP>y<SP>,</SP> P<SP>1</SP>y' from the control computer representing X co-ordinate displacement of point of impact of beam, X coordinate of origin, Y co-ordinate displacement, and Y co-ordinate of origin which are combined over scaling units 54, 74 and adders 55, 75 to produce X and Y deflectional corrected analogue signals RMN (Px + A.Lx) and RMN (Py + A.Ly).

Title: Attenuated negative strand viruses with altered interferon antagonist activity for use as vaccines and pharmaceuticals
IPC: A61K35/76
Filed: 2000-12-12
Abstract: The present invention relates, in general, to attenuated negative-strand RNA viruses having an impaired ability to antagonize the cellular interferon (IFN) response, and the use of such attenuated viruses in vaccine and pharmaceutical formulations. The invention also relates to the development and use of IFN-deficient systems for selection of such attenuated viruses. In particular, the invention relates to attenuated influenza viruses having modifications to the NS1 gene that diminish or eliminate the ability of the NS1 gene product to antagonize the cellular IFN response. The mutant viruses replicate in vivo but demonstrate reduced pathogenicity, and therefore are well suited for live virus vaccines, and pharmaceutical formulations.
