摘要： A high voltage disconnect switch, including a countercontact piece having switch countercontacts and being arranged for connection to a source of high voltage. Resilient pre-contact pieces are insulatingly connected to the countercontact piece and include switch contacts disposed for contacting the switch countercontacts. Movable primary contact pieces are arranged to be movable from a first position of separation from the pre-contact pieces and the countercontact piece to a second position in which the primary contact pieces are in contact with the pre-contact pieces but not with the countercontact piece and to a third position in which the primary contact pieces are in contact with both the pre-contact pieces and the countercontact piece. The pieces are configured and arranged relative to one another so that during the closing of the switch the countercontacts contact the contacts after the primary contact pieces are moved to the second position and before they are moved to the third position, and during the opening of the switch the countercontacts separate from the contacts after the primary contact pieces are moved to the second position and before they are moved to the first position.

摘要： A puffer-type gas blast circuit interrupter composed of two separable contacts defining a power current path and between which an arc is created upon separation movement, in which the movable parts of the gas compressor and/or the region of contact between the contacts of an associated nominal current path are shielded from the region in which the arc is created by a shielding arrangement composed of a stationary cylinder surrounding the nozzle associated with the gas compressor and a shield member carried by the nozzle. Additionally, to reduce the movable mass of the interrupter, at least one of the current paths is constituted by two stationary contact pieces and a movable contact member carried by, and projecting from, the cylinder of the gas compressor. Further, the mass of the moving parts of the system is reduced by providing the shield member carried by the nozzle with a cylindrical projection coaxial with, and slidable relative to, the stationary cylindrical member. Preferably, the interface between the shield member and the cylindrical member is hermetically sealed.

摘要： The invention discloses a gun barrel with a novel pattern of a rifling curve. The latter proceeds at start of motion from the parabolic curve y=A+Bx+Cx.sup.2 and is supplemented with a constant D, to which is added a freely selectable exponent =d. Due to the freely selected exponent as parameter the ridge force maximum can be displaced at almost equal level between the start of motion and the barrel mouth. At the barrel mouth the ridge force drops to a minimum.

摘要： Spherical, hard mono- or oligodisperse particles of diameter from 0.1 to 100 .mu.m are prepared by condensation of partially etherified melamine-formaldehyde precondensates which form a clear solution in water in every ratio, in an aqueous solution of a water-soluble polymer which has strongly acid groups and a K value of from 100 to 160, at pH 3 to 6 and at 20.degree. to 100.degree. C., and condensation of the resulting cloudy solution is continued until the precondensate has been consumed, resulting in a dispersion of the particles. The dispersion is neutralized. The particles can be used in the form of the aqueous dispersion or after isolation from the dispersion.The particles are spherical, hard and non-swellable and can be used, for example, as sizes for plastics, polishes, delustrants, extruders and/or as pigment.The process makes it possible to produce particles of predetermined size and size distribution.

摘要： A projectile particularly for use in rapid fire weapons and high performance guns comprises a hollow projectile body having an exterior surface with an annular groove therearound and with a plurality of openings formed in the groove at spaced circumferential locations. A rotating band is positioned in the groove and secured against displacement caused by centrifugal and accelerating forces, portions of the band which extend through the openings. The band is advantageously injection molded directly in the groove so that portions thereof form into the openings and extend through the openings and form a closed ring on the interior of the shell of the projectile body.

摘要： A projectile particularly for automatic firearms in high performance machine guns comprises a cylindrical projectile body which has an annular groove around its circumference with rib portions extending radially outwardly of the bottom of the groove which are of radial extent no greater than the outer surface of the projectile body. The groove has end walls which are substantially perpendicular to the exterior surface of the body. A plastic rotating band has its inner periphery anchored in the groove with the rib portions extending to receiving recesses or grooves of the band. The ribs are advantageously radially extending elements which have their outer ends bent in axial directions and they are arranged so that there are portions of the groove of the body on each side thereof. In accordance with the method of manufacturing a projectile body, a form tool is used to effect the recessing of the projectile body or jacket to produce the intermediate ribs which are of substantially rectangular cross section. Thereafter the ribs are bent in a desired direction under a pressure application while simultaneously producing knurls or a roughened surface on the ribs. Thereafter the rotating band is formed in the groove and projects outwardly from the surface of the projectile body. The band is formed by injecting a preferably fiber filled sooth pigmented plastic into the projectile body grooves and around the ribs which are formed in the groove.
