Abstract: ABSTRACT OF THE DISCLOSURE          An actuating mechanism for a toggle or slider switch in which the rocking or sliding motion of the switching lever of the switch is converted by means of a mounted shift lever device into a rotational motion.  The rotational motion operates a plate-shaped coupling member which is provided with an opening which matches the shape of the rocking or sliding lever.  The size of the opening increases outwardly from a plane lying within the plate towards the outer surface of the plate. The plate in turn is mounted in a fork shaped lever by means of a peripheral groove in the plate which permits the plate to slide in the fork of the lever.  The lever in turn is mounted on a shaft in a housing which can be mounted on the switch to provide a bearing for the shaft.

Abstract: ABSTRACT OF THE DISCLOSURE      The present disclosure is directed to a fluid line pressure monitor insertable in a pipe line having a pressure side and an vent side.  The monitor comprises a pair of strip members joined along their longitudinal edges and the ends of the monitor being passed over the ends of a bread in the pipe line.  The inside of the strip members is subjected to the pressure of the fluid being passed through the pipe and the outside of the strops being subjected to the hydrostatic pressure in a receptacle or pressure within a chamber which is pressurized from a source to be monitored.  The strips may be both of an elastomeric material or a flexible metallic material or a combination of one elastomeric material and one flexible metallic material so long as the two strips are fused along their longitudinal length and fit snugly about the ends of a pipe through which a fluid flow passes from a pressure side to a vent side.  The monitor is placed in a receptacle at a fixed distance above the bottom and subjected to a hydrostatic head which may vary with the fluid depth in the receptacle. Uspstream of the monitor is a gauge or chart recorder which will measure the effect of the hydrostatic head in the receptacle on the monitor relative to the pressure passing through the monitor form pressure fluid passing through the pipe line.

Abstract: ABSTRACT OF THE DISCLOSURE         Method and apparatus for separating isotopes of an element in an atomic or molecular mixture.  The isotropic recoil momenta resulting from selective excitation and ioni-zation of an atomic beam is used to mechanically separate a desired isotope from the beam.  Similarly, the isotropic recoil momenta resulting from selective photon excitation and promotion of dissociative electron attachment of a molecular beam of uranium hexafluoride is used preparatory to mechanical separation.  The isotropic recoil momenta resulting from multi-photon dissociation recoil in a molecu-lar beam of UF6 or SF6 is also used for separation.  And, matrix formation of UF6 in HBr so as to collapse the .gamma.3 vibrational mode of the UF6 molecule is used in conjunction with selective isotopic excitation to promote reduction of UF6 molecules containing U235 and facilitate simplified separation.

Abstract: ABSTRACT A full-caliber shell for training purposes is intended to be fired with a low charge in a large-caliber firearm, e.g. a howitzer or a gun.  The shell comprises a front part made of heavy material, an effect part with a casing and a bottom unit.  The effect part casing and the bottom unit are substantially made of plastic material which is highly resistant to, inter alia, high pressures.  The effect part casing and the bottom unit are arranged to withstand the great stress forces which arise in connection with the firing of the shell in the howitzer when the heavy front part is to be accelerated by means of the effect part and bottom unit.  The stress forces are then very pronounced, and are of the magnitude of those arising in connection with the firing of a steel shell with the corresponding charge.  The heavy front part, the effect part with its charge, and the bottom part are carefully balanced in relation to each other so that they give ballistics and a weight which makes the new shell substantially equal to the steel shell which the new shell is to supersede.  In addition to the effect part casing the effect part comprises a tubular unit arranged coaxially in the effect part casing.  The effect part casing and the tubular unit are connected with spoke elements which extend in the longitudinal direction of the effect part and along parts, particularly substantial parts, of same.  The new shell can be made at a very low cost, has a small risk zone at impact, and gives a good indication effect and great safety in the barrel.
