Title: Double-barrel bolt action repeating firearm
Inventor: SZECSEI JOZSEF
IPC: F41A19/18
Filed: 1992-10-16
Abstract: A bolt assembly is provided fox a double-barrel repeating firearm, such as a rifle or a shotgun. The bolt assembly is adapted to fit in the receiver of the double-barrel firearm. The halt assembly comprises a bolt body which connects to first and second breech bolts, and which also couples to a halt collar. The bolt collar has a bolt handle for operating the bolt assembly. The bolt body and breech bolts have recesses for accepting first and second firing pin assemblies. The firing pin assemblies include first and second cocking pieces, which are both cocked by the action of the bolt collar. Once cocked, the cocking pieces can be released independently of each other for firing using the trigger. Pulling the bolt assembly rearwards ejects the fired cartridges through an ejection port on the receiver. The receiver also includes a cartridge injector port which couples to a magazine capable of storing additional cartridges. During the forward travel, the bolt assembly reloads the firing chambers with cartridges from the magazine.

Title: Radon removal system
Inventor: MATSON STEPHEN L
IPC: B01D19/00
Filed: 1991-06-17
Abstract: Method and apparatus for removing dissolving radon gas from water for the purpose of reducing the exposure of house-hold occupants to elevated airborne radon levels. Radon removal is accomplished by a membrane - mediated air stripping pro-cess which is based on the passage of radon from water (28) flowing along one surface of the membrane to stripping air (27) flow-ing along the second surface of the membrane. Particularly careful are dense polymeric membranes comprised of silicone rubber and hydrophobic microporous membranes.

Patent CA-2095828-A1 (CA)
Inventor: KALBACK WALTER M
IPC: C10C3/08
Filed: 1991-12-05
Abstract: This invention relates to low melting solvated mesophase pitches which are suitable for spinning into carbon fibers. The solvated mesophase pitches have a lower melting point than conventional mesophase pitch but remain substantially anisotropic. The solvated mesophase can be produced as an intermediate during solvent fractionation or supercritical solvent fractionation of mesogen-containing isotropic pitches. The process is enhanced through the ability to recover pseudomesogens with an increased average molecular weight which, in combination with the solvent content, provides a fusible mesophase capable of being spun directly into infusible oriented anisotropic carbon fibers.

Filed: 1993-01-14
Abstract: ABSTRACT       Inorganic or organic particles have been used in the past as paper additives for hot-pressed forms to impart the pattern of granite thereto, but when these are boiled in hot water, for example, an uncountable number of small blisters result,  lowering  the  commercial  value of  the  product; however, according to the present invention it is possible to obtain an additive  for forming patterns by grinding to desired particle sizes colored paper which has undergone water-resistance treatment with a thermosetting resin, and by selecting the color of the colored paper, a pattern may be selected  as  desired  having spots  of  any  desired color or size.  With patterned paper manufactured by adding these paper additives during the paper manufacturing process, there is no occurrence of the above mentioned blisters and a clear pattern may be  formed,  and  therefore hot-pressed  forms utilizing have a natural granite image.
