Patent CA-2814923-A1 (CA)
Title: Gauge kits for sheet bending brakes
Inventor: CLOUTIER ALEXANDRE
IPC: B21D5/04
Filed: 2013-04-30
Abstract: A sheet metal bending brake consists of a flat surface onto which sheet material is placed, and a clamping bar which comes down and holds the sheet material firmly during the bending process. However, errors in measurements and difficulties in supporting the sheet material increase the time per bend, the cost of labour, and wasted material. Accordingly, it would be beneficial to provide the brake user with fixed and demountable gauges allowing for improved accuracy, reduced errors, reduced waste, and reduced need for support personnel. Embodiments of the invention provide for such kits to be provided supporting both fixed and demountable gauges with flexibility in length as well as supporting both ruled dimensions and visual markers / stops.

Title: Shutoff valve for a flexible tube
Inventor: ARVOLA TOMAS
IPC: E21F1/08
Filed: 2012-03-08
Abstract: The claimed invention relates to a valve, specially designed for control of flows in flexible tubes or pipes. The purpose is to provide such an appropriate valve that is compact, that does not require considerable maintenance, and that can be completely closed. This is achieved in a valve that comprises two semicircular elements of different radii. These semicircular elements are pivotally connected at both their ends by means of hinges, and enclose the flexible tube or pipe completely. The opening degree of the valve is controlled by the relative rotary position of the semicircular elements so that the flexible tube or pipe is not constricted when the semicircular elements form a circle, and the flexible tube or pipe is maximally constricted when the semicircular elements form a half circle.
