Abstract: A group of hydro-monobenzoporphyrins "green porphyrins" (Gp) having absorption maxima in the range of 670-720 nanometers is useful in treating disorders which are subject to hematoporphyrin derivative (HPD) treatment in the presence of light.  The use of the Gp of the invention permits the irradiation to comprise wavelengths other than those absorbed by blood.  The Gp of the invention may also be conjugated to receptor ligands or to specific immunoglobulins or fragments thereof to target specific tissues or cells for the radiation treatment.  Use of these materials permits lower levels of drug to be used, thus preventing side reactions which might destroy normal tissues.

Granted: 1993-03-02
Abstract: Abstract of the Disclosure METAL SHEARING MACHINE           Two  shearing  blades  disposed  along  two  lines which intersect each other are carried on the bottom edges of two adjacent walls of a four-sided ram structure.   The ram is supported at four points whereby to provide greater stability.    The workpiece is carried on the aligned top surfaces  of a  fixed bed and a movable carriage.    The movable carriage is movable in a first direction.   Finger grippers,  joined by a connecting bar, are movable in slots along the top surface of the movable carriage in a second direction.    Thus,   the workpiece is moved in the first direction by movement of the movable carriage and in the second direction by movement of the finger grippers.   The workpiece may be precisely and accurately positioned under the shearing blades making use of sensors in each of the finger grippers and a lateral sensor at the end of the movable  carriage.    The  drives  for driving  the movable carriage  and  the  finger  grippers  are  controlled  by  a processor which  also receives  feedback signals  from the drives  indicative of the distances moved by the movable carriage and the finger grippers.

Abstract: ABSTRACT OF THE DISCLOSURE         A control method controls a belt-and-pulley type continuously variable transmission having drive and driven pulleys mounted respectively on input and output shafts, a V-belt trained around the drive and driven pulleys, and an oil pressure source and an oil reservoir operatively coupled to first and second hydraulic pressure chambers for axially moving the movable conical members of the drive and driven pulleys to vary effective diameters of the drive and driven pulleys for thereby controlling a speed ratio.  The movable conical members of the drive and driven pulleys are movable in synchronism with each other.  The hydraulic pressure chamber of one of the drive and driven pulleys the effective diameter of which is to become larger at that time, is first brought into communication with the oil pressure source.          The hydraulic pressure chamber of the other of the drive and driven pulleys the effective diameter of which is to become smaller, is brought into communication with the oil reservoir no earlier than the communication of the hydraulic pressure chamber of the one of the pulleys to the oil pressure source, for thereby starting to move the movable conical members.

Title: Fin-stabilized subcaliber projectile and method of spin tuning
Inventor: FELDMANN FRITZ K
IPC: F42B10/06
Filed: 1988-07-19
Granted: 1993-01-19
Abstract: ABSTRACT      The invention concerns a fin-stabilized projectile for employment from a rifled barrel and is particularly suitable for automatic cannons having calibers from 12.7 to 70 millimeters.  The full rate of spin commensurate with the rifling twist of a specific barrel and the muzzle velocity is imparted to the projectile during launch using a rotating band which is fixed and an integral component of the discarding sabot.         Subsequent to exit from the muzzle of the gun the rate of spin of the projectile is decelerated rapidly by aerodynamic damping to avoid potential adverse effects due to Magnus moment.  The aerodynamic design of the fins is such that the projectile spin reaches a steady state rate of spin which is at least 50 percent larger than the mutation frequency of the projectile.  by means of this spin tuning resonance instability and roll lock-in are avoided over the operational range of the projectile.  Launching at full rate of spin also results in large centrifugal forces acting on the components of the sabot which provides for instantaneous and precise sabot separation upon projectile exit from the muzzle.  This combined with the highly repeatable and reliable tuning of the projectile spin rate permits excellent projectile accuracy and dispersion characteristics.  The invention also includes a discarding sabot design incorporating an integral, fixed rotating band.         The design involves the in-place injection molding of the sabot body including a seal with obturator onto the fin-stabilized projectile.  The absence of slipping rotating band provides for a rugged sabot configuration which is particularly important for ammunition employed from automatic cannons.

Title: Method for regulating the amount of air supplied to a gas mask and a gas mask, in which this method is implemented
Inventor: PONKALA JORMA
IPC: A61M16/00
Filed: 1989-04-04
Granted: 1992-10-13
Abstract: Abstract The invention relates to 2 method by which the amount of air supplied to a gas mask is kept essentially constant by using the fan motor (1) as a sensor, with the aid of which its po-wer is regulated. The electronic regulation circuit of the in-vention keeps the air amount constant by regulating the pulse width ratio of the voltage (U1) operating over the motor. The light emitting diode (LED) connected to the cont-rol circuit detects when the fan motor is unable to produce the selected amount of air. In order to prevent deep dischar-ge of the battery, the voltage supervising circuit (6) inter-rupts the current supply to the device when the supplied vol-tage (SJ) drops below the set limit value.
