Title: Seismic brake
Inventor: KEMENY ZOLTAN A
IPC: F16L3/10
Filed: 1995-03-22
Abstract: A seismic brake assembly (100) comprises an annular pipe (1) journaled through a gripping block (2) which frictionally engages the pipe (1) about the pipe's outer diameter. The force with which the gripping block (2) frictionally engages the pipe (1) is controlled by a Belleville or spring-loaded washer (9). By securing the gripping block (2) to one point in a structure (11) and securing one end of the pipe (1) to another point in or associated with the same building or structure (11) to be supported, the seismic brake (100) functions as a rigid member of applied lateral stresses less than a design threshold. When the applied lateral forces exceed the design threshold, controlled sliding friction between the pipe (1) and gripping block (2) is experienced, whereupon the building or structural framing returns the seismic brake (100) to its normal position when the seismic activity ceases. By controlling various factors including the diameter of the pipe (1) and the tension with which the gripping block (2) engages the pipe (1), virtually any desired hysteresis loop may be achieved.

Patent CA-2192041-A1 (CA)
Title: Gas-tight container
Inventor: SEVERUS HARALD
IPC: B65D8/12
Filed: 1996-12-04
Abstract: Gas-tight container featuring an outer shell of metal or metal and plastic or metal and cellulose-containing material, a base, a lid and at least one side-wall. The container may be e.g. a can with - as viewed in plan view - a polygonal, round or oval cross-section. The base or part of the base of the gas-tight container exhibits a region which may be made to bulge and which is surrounded by an endless depression and, in the condition in which the can may be used, is in the form of a concave bulge. A container of this kind is such that one can readily recognise if the contents have suffered from spoiling or decomposition and, as a consequence, gas has been formed inside the container. If the pressure inside the container increases, the bulge is pushed outwards and, usefully, may form a convex bulge. If the bulge is pushed out by the increase in internal pressure, it projects beyond the outer limits of the container base rim, as a result of which the linear or ring-shaped contact the base rim makes with an underlying surface changes to two point contact and the container indicates a chemical or physical change by its instability on an underlying surface.
