Abstract: A pressure lock for a gas system with a regulator, the pressure lock comprises a pressure lock body to be fluidically connected in said gas system, whereby gas can pass from a chamber in the body via lock connection means to the gas system and activation means for delivering gas from said pressure lock body and into the gas system thereby providing a lock-up pressure, whereby the gas from said pressure lock body provides an increased pressure in the gas system, whereby the regulator is blocked for a short period of time thus allowing the detection of leaks in the gas system downstream of the regulator.

Abstract: Suitcase for transport of tools or the like, which includes a box-shaped bottom (1), a corresponding lid (2) and a flip-up handle (3) on the side of the bottom (1). The bottom (1) and the lid (2) are connected with each other by one or more hinges. A lock is provided for locking the lid (2) to the bottom (1), and said lock includes a latch device (4), which is turnably mounted on the bottom (1) on the same side of the suitcase as the handle (3). Said latch device (4) is adapted so that by turning, it engages with the lid (2) and fixes the lid in its closed position. The latch device (4) and the handle (3) have interacting cam means (22 and 23), which effect turning of the latch device (4) into the locked position when the handle (3) is turned to flipped-up position.

Abstract: A pair of clip-on spectacles for fastening on another pair of spectacles, where the clip-on spectacles includes a pair of glasses which are interconnected by an resiliently bendable bridge with a hook at the middle of the bridge for fastening behind the bridge of the other spectacles, where the bridge of the clip-on spectacles is resiliently prestressed towards the hook so that by fastening on the other spectacles, the glasses of the clip-on spectacles are pressed against the glasses of the other spectacles.
