Abstract: Novel composite explosives which comprise a molecular explosive and oxidizing salt combinations in intimate contact are described in this invention. The high degree of intimacy between the molecular explosive and the oxidizing salts has been attained by means of the melt-in-fuel emulsion technology. Accordingly, highly dense compounds which have a dispersed phase showing very small mean particle size are obtained. Emulsification between both phases takes place within seconds and therefore the composite explosive can be prepared by simply agitating vigorously or by injecting both molten phases through a static mixer. The method described allows one the use of a wide variety of different oxidizing salts and different molecular explosives. The final products obtained show good rheological properties and consequently admixing of additives is possible. The compounds of this invention can substitute the current army melt cast explosives and can also be applicable as boosters for industrial use.

Title: Electron cyclotron resonance plasma source and method of operation
Inventor: DANDL RAPHAEL ANTHONY
IPC: H01L21/205
Filed: 1990-03-08
Abstract: A method and apparatus are disclosed employing electron cyclotron resonant (ECR) heating to produce plasma for applications including but not limited to chemical vapor deposition and etching. A magnetic field is formed by magnets circumferentially arranged about a cylindrical and symmetrical chamber with microwave power injected perpendicularly to a longitudinal axis of the chamber for preventing line-of-sight communication of resulting energetic electrons through an outlet at one axial end of the chamber. The circumferential magnets in the symmetrical chamber cause precessing of the electrons resulting in greatly increased plasma density and ion flux or current density even at low gas pressures which are preferably maintained for establishing unidirectionality or anisotropic plasma characteristics. A magnetic field free region is formed between the plasma forming region containing the microwave power source and the circumferential magnets in order to also produce uniformity of plasma distribution in a plasma stream approaching the outlet. Thus, with specimens aranged in communication with the outlet, the above characteristics are maintained for the plasma stream over substantial transverse dimensions larger than the specimen.

Abstract: On décrit des procédés et composés nouveaux permettant d'introduire un gène tueur, à savoir un gène capable de tuer une cellule ou d'inhiber sa croissance, dans une cellule cible spécifique. On prépare notamment une particule virale à réplication sensiblement défecteuse ayant des capacités de ciblage pour un type spécifique de cellules. Soit la glycoprotéine superficielle de la particule virale native fournit le ciblage, soit on modifie ladite glycoprotéine superficielle de manière à introduire un élément d'une paire de liaison spécifique, tel qu'un anticorps, ou un fragment de celui-ci à un antigène spécifique de tumeur, une protéine virale exprimée par une cellule infectée par virus, ou un ligand de récepteur. La particule virale se dirigera donc vers la cellule cible normale pour le virus ou vers une cellule comprenant l'autre membre de la paire de liaison spécifique. C'est grâce au gène tueur intégré dans la particule virale, que cette dernière est capable d'inhiber la croissance.

Abstract: A spring-and-spacer assembly for maintaining fuel rods (82) in a upright preferred position in a fuel assembly of a nuclear reactor core is provided. The spring 92 has a leg portion 106 and two loop portions 116,118, one at each end of the leg. Each loop engages an ear 132,134 formed in a ferrule 136 of the spacer. Each loop contains a dimple 122,124 which contacts an ear 132,134 of the ferrule 136. The central leg portion 106 has a dimple 108, or a projection, which contacts a fuel rod 82 and biases the fuel rod against stops 148,152. The spring load is transmitted to the ferrule ears 132,134 by the dimples 122,124 in the spring loops. Preferably, the spring rotates about the dimple 122,124 when flexed, contributing to spring flexibility. The high spring flexibility permits use of the spring in connection with small rod-to-rod spacing fuel assemblies. This construction permits providing a low-mass, low-surface area spring, in turn providing for low neutron absorption and low flow obstruction.

Abstract: A method of reducing slice profile degradation due to gradient signal amplitude ripple, has steps of: sensing the gradient signal ripple amplitude; normalizing the sensed ripple signal amplitude responsive to the gradient amplitude commanded; and modulating the RF signal amplitude with the adjusted-amplitude ripple signal, to cause the RF and gradient magnetic fields to have an effective vector pointing substantially in the same direction, during the slice-selection interval, as would the effective field vector formed with a gradient field devoid of ripple. Apparatus for reducing the slice profile degradation modulates the RF signal with the ripple envelope obtained from the output of the gradient signal amplifier, by a signal controlled by the gradient amplifier input.

Abstract: The device has the same number of invalidating units (E) arranged next to one another as there are longitudinal rows of printed vouchers provided on the print carriers (P). Each invalidating unit (E) has a frame (1), a trough (3) which is vertically displaceable therein for receiving ink (4), an impeller (7) which rotates constantly above the trough (3) and a shutter (11) which interacts with an opening (10) of a hood (9) which covers the impeller (7). The trough (3) is adjustable by a controlled adjustment element (6) between a raised operating position in which the impeller (7) dips into the ink and the shutter (11) releases the opening (10), and a lowered position of rest in which the impeller (7) does not dip into the ink and the opening (10) is covered by the shutter (11). The control takes place in each case whenever a printed voucher in one or more of the longitudinal rows of the print carriers, which is to be invalidated after having been detected as an incorrect print, passes the opening (10) of the invalidating unit concerned so that this faulty print is sprayed with ink by the impeller (7) through the opening (10) which is then free.
