Patent CA-2523878-C (CA)
Title: Device for braiding hair
Inventor: BROUILLARD PATRICK M
IPC: A45D8/34
Filed: 2005-10-28
Granted: 2013-09-17
Abstract: This invention describes a device intended for braiding hair. The device comprises two plates that make up part of the device, and which includes an arm operated by a motor that turns a dividing roller via a transfer drive to open an arm to engage the hair braids and closes under a spring action to form three bunches via two forks, and from where the arm returns to its initial position when the tension springs pull the two forks back. Cams operate a locking component to release the drives and enable the rotation movement of the two dividing arms used to push the bunches via two rollers to form braids, and a portion of the drive transfers the rotation movement of the dividing roller via the drives at each quarter-turn.

Granted: 2012-01-31
Abstract: The invention relates to a device for the reactive conversion of gaseous streams at high temperatures in excess of 1000 ~C. Said device comprises a reaction chamber (8) with an inlet opening for the gaseous streams to be converted, in particular a burner head (2) and an outlet opening for the converted gaseous streams. In order to guarantee the highest possible conversion performance, the reaction chamber (8) has a narrow construction, extending longitudinally from the inlet opening to the outlet opening to form a controlled gaseous flow, thus preventing a circulatory flow in the reaction chamber (8). To achieve reaction conditions that are as adiabatic as possible, the reaction chamber (8) is thermally insulated with a layer (7) that has a porous foam and/or fibre structure. In the simplest embodiment, the reaction chamber (8) is cylindrical, thus achieving a tubular flow reactor construction for the entire device.
