Abstract: A bottle support is provided to hold a bottle in suspended relationship and in such a manner as to be locked to the bottle so that the contents of the bottle can be poured without detachment occurring between the bottle and the support. To enable a mounting of the support atop the bottle, the support is provided with a keyhole-like opening having a first section which is an enlarged lobe which permits the penetration of the neck of the bottle through opening in the support and a second section which is smaller and permits engaging beneath an annular rib which is located on the neck of the bottle. To permit a tilting of the skirt of the support as the support is being mounted on the bottle, the skirt is provided with a cut away portion adjacent the handle which is provided on the skirt.

Abstract: A housing for a fire detector has a circumferential area including a series of vanes or slats, each positioned at an angle with respect to the tangent at the periphery of the housing. The angle is about 45.degree., which not only allows ready entrance of gases through the major portion of the "window" defined by the vanes, but also prevents particles from passing straight through the housing and out the other side. This effects good mixing of the gases, better detection of combustion particles, and also decreases the likelihood of spurious or incorrect signals due to extraneous air currents.
