Abstract: The invention relates to a patient ventilation or breathing device and components therefore for use in all forms of respiratory apparatus ventilation systems including invasive and non-invasive ventilation, positive airway pressure therapy, Continuous Positive Airway Pressure (CPAP), and particularly Bi-Level therapy and treatment for sleep disordered breathing (SDB) conditions such as Obstructive Sleep Apnea (OSA), and for various other respiratory disorders and diseases. The invention particularly relates to a blower, to a blade, to a gasket, to a cable, to an impeller, to a gas inlet and inlet member, to an improved air path or fluid flow path and components thereof, and/or to a modular ventilation or breathing device as referred to above and particularly incorporating one or more of the other aspects of the invention.

Abstract: Described is a cooling device for cooling an equipment component with the aid of a cooling agent, as well as a method for cooling an equipment component. In at least one embodiment, the cooling device includes a heat source for transferring thermal energy from the equipment component to the cooling agent and a heat sink for dissipating thermal energy from the cooling agent. The heat source and the heat sink are connected to each other. The cooling agent can be supplied via a forward flow line to the heat source and can flow via a return line away from the heat sink. The cooling device includes a control mechanism and two storage containers or a stratified storage tank for the cooling agent. The control mechanism is connected to the two containers and/or the stratified storage tank, the forward flow line and the return flow line.

Abstract: With the invention is presented an anti-theft device for bicycles, which comprise a bicycle frame (2) and a steering column (14) mounted on the bicycle frame (2) for steering the bicycle, which steering column is provided for a rotationally fixed coupling of bicycle handlebars (6) with a fork (5) for a front wheel (4), having a separating means for nuetralising the rotationally fixed coupling, wherein a coupling piece (8) or a connecting element (60) is provided as separating means, which divides the steering column (14) into two parts (34) and produces the rotationally fixed coupling of these steering column parts (34) in a first state and neutralises it in a second state.
