Abstract: A pressure monitor for a breathing system is disclosed which includes three switches, each of which is connected to the breathing system and each of which is preset to be changed in state when the switch is connected to a pressure which is in excess of a predetermined threshold pressure. Each of the switches has a different predetermined threshold with the monitor further including signal means, timing means and selector means. The selector means is connected to one of the switches at a time. The timing means is responsive to the one switch connected to the selector and the signal means is connected to the timing means. The signal means is activated by the timing means whenever the system pressure does not exceed the threshold of the switch connected to the selector means within a predetermined time interval. The selector means includes display means for displaying the threshold pressure of the switch connected to the selector means so that the pressure monitored is readily apparent.

C. range.

Abstract: A readily removable closure panel for an opening in a roof or wall of a vehicle and including a quick release hinge means for permitting partial opening of the panel and for rapid disengagement and removal of the panel from the roof. An adjustable hinge construction for a panel wherein the hinge construction includes a resilient yieldable hinge member which provides a hinge edge for releasable pivotal engagement with a cooperable frame portion of a frame member defining an opening in the roof. The hinge edge engagement provides a hinge axis beneath or interiorly of the panel margin and the hinge edge is adjustably spaced therefrom for causing the panel edge margin to press against a resilient gasket on the frame member in both closed and partially opened position of the panel.

Abstract: A bipolar electrode for an electolyser. It is characterized in that the anode surface and the cathode surface of said electrode both comprise a porous conductive material which includes sintered nickel previously impregnated with nickel molybdate. The invention is used for manufacturing hydrogen by electrolysing an aqueous alkaline solution.
