Abstract:
Apparatus and methods for detecting an incipient fire condition based on a shift in the size distribution of particles generated by a developing incipient fire condition. Particulate mass concentrations of at least two different particulate sizes are monitored and the ratio of the outputs from the sensing devices (22, 24) is processed as an indication of an incipient fire condition. In another form of the invention, the rate of change of the ratio of the outputs from the monitoring devices (22a, 24a) is processed as an indication of an incipient fire condition.
Abstract:
Golf club shaft (1, 2, 3) tapered in a step pattern and having a high deflection point. The grip area (2) has a smaller diameter than the adjacent steps of the taper section (1) of the shaft.
Abstract:
A low twist, high bulk filtration roving is prepared by wrapping a sliver comprised of individual fibers, around a core in the conventional manner. Exemplary of the bulk fibers which may be employed are naturally occurring fibers such as jute, cotton, animal hair; synthetic polymer fibers, such as acrylic, nylon, polyester, olefin, aramid, teflon; man-made organic fibers deriving from natural sources such as rayon or cellulose acetate; and inorganic fibers such as metal, glass, graphite; or a blend of two or more of these fibers. Examples of the core, which can be continuous filaments, monofilaments or spun yarn, are one or more strands of the same composition as the fibers, or a combination thereof, twisted paper which can be plain, impregnated or metallized, and metal wire. Where the material is capable of being cast in film form, slit film may be employed as the strand(s). The composite roving is wound upon a rigid perforated tubular center to form a filter cartridge.
Abstract:
A game in which each opposing player utilizes a racquet, a paddle (16), or a hand to propel a ball onto a game board apparatus having three playing surfaces (e.g., 40, 42, 44). These playing surfaces are related to one another at angles which are within a specified range. The rules of the game require that the ball come into contact with the surfaces in a specified order both while serving and during play. The game utilizes a game board that may be incorporated into furniture, (Fig. 1) may be wall mounted (Fig. 7), or may be on a free-standing base (Fig. 5).
Abstract:
Ultra light weight golf club shaft (1) tapered in a step pattern (2) having a reinforced wall (5) at the region of the grip (4) where maximum bending moment occurs during play.
