摘要： 1,2,6-Thiadiazine-3,5-dione-1,1-dioxides of the general formula ##STR1## wherein each R and R.sub.3 independently may be substituted or unsubstituted alkyl, alkenyl or substituted cycloalkyl are described. These compounds, as well as those wherein the R substituents additionally may be cycloalkyl or substituted or unsubstituted aryl, are useful as accelerators for the peroxidic polymerization of ethylenically unsaturated compounds, such as methacrylic acid compounds, and have particular utility in dental compositions.

摘要： A setting device includes a driving piston propelled by high pressure gases through a casing for driving fastening elements into a receiving material. A stop device located within the casing secures a stop element in a recess in the driving piston for holding the piston in the firing position. The stop device includes a first spring and a second spring each biasing the stop element into the recess. The first spring has a greater biasing force than the second spring. To release the driving piston from the firing position so that it can drive a fastening element into a receiving material, the propelling forces acting on the piston displace the stop element against the force of the springs and then the first spring biases the stop element against the second spring. After the stop element is displaced out of the recess only the second spring acts on the stop element so that movement of the driving piston relative to the stop element is effective without any appreciable holding action limiting such movement.
摘要翻译：设置装置包括通过用于将紧固元件驱动到接收材料中的高压气体推动的驱动活塞。位于壳体内的止动装置将止动元件固定在驱动活塞中的凹部中，用于将活塞保持在点火位置。止动装置包括第一弹簧和第二弹簧，每个弹簧将止动元件偏置到凹部中。第一弹簧具有比第二弹簧更大的偏置力。为了将驱动活塞从击发位置释放，使得其能够将紧固元件驱动到接收材料中，作用在活塞上的推进力抵抗弹簧的力移动止动元件，然后第一弹簧将止动元件偏压抵抗第二春在止动元件从凹部移出之后，仅第二弹簧作用在止动元件上，使得驱动活塞相对于止动元件的运动是有效的，而没有任何明显的保持动作限制这种运动。

摘要： An improved opaque, photopolymerizable dental filling material is provided comprised of acrylic acid ester compounds containing mono and/or polyfunctional acrylic or methacrylic ester compounds, photoinitiators, pigments and possibly activators and silicon dioxide or silicate fillers, the improvement comprising the presence of finely divided calcium fluoride as a white pigment in a quantity of from 1-20 percent by weight. The presence of the calcium fluoride enables an opaque effect to be achieved without reducing the permeability of the filling material to polymerization radiation.

摘要： In a setting gun using explosive force for driving fastening elements into a receiving material, an elastic damping device is provided to absorb the residual kinetic energy of a driving piston. The damping device consists of a plurality of serially arranged pairs of rings extending between a muzzle tube and a stop ring mounted in the forward end of a barrel. Each pair of rings consists of a radially inner ring and a radially outer ring each having a frusto-conical surface in contact with the other. The frusto-conical surfaces converge in the firing direction of the setting gun. In one embodiment, each pair of rings has the same axial length, however, in another embodiment the axial length of the rings increases in the firing direction of the setting gun so that the mass of the pairs of rings increases in the firing direction.

摘要： A powder charge operated fastening element setting device includes a housing, a barrel forming an axially extending bore with the barrel being axially and rotationally displaceable within the housing. An axially extending driving piston is located in the barrel bore and is axially displaceable therein between a ready-to-fire position and a fired position. A guide bush is located within the housing at the rear end of the barrel and is coextensive with an axially extended part of the barrel. The guide bush is secured against rotation relative to the housing. Propellant gases are generated in combustion chamber in the guide bush and flow into the barrel bore. The force of the propellant gases for propelling the driving piston can be regulated by at least one outlet opening adjacent the rear end of the barrel which can be selectively connected to an outlet flow duct in the guide bushing which opens to the atmosphere. By rotating the barrel the outlet opening can be moved into or out of communication with the outlet flow duct.
