Abstract: In order to obtain a high precision of measurement which is independent of the soot content of the exhaust gas to be tested in a given process, the proposal is put forward that the volume of exhaust gas taken for each loading of the filter be determined by means of a suitable algorithm from the value of filter blackening obtained in a previous test, sampling being continued if the blackening of the filter is outside a specified range.

Abstract: An apparatus for removing carbon dioxide from a body of air by using a regenerative solid amine material arranged in beds 14(A-D) is disclosed. Air is directed through a first bed to adsorb the carbon dioxide therefrom. Steam is impelled by a compressor (24) into the first bed to desorb that bed, the steam forming a condensate on that bed. The compressor then creates a vacuum in the first bed which vaporizes the condensate therein, dewatering the first bed so that it may be reused to adsorb carbon dioxide. The compressor impels the vaporized condensate into a second bed to desorb the adsorbed carbon dioxide in the second bed.

Abstract: Air contaminated with chemical and biological pollutants is purified by treating chemically and electrochemically in a closed system minimizing the generation of by-products for disposal. Pollutants are treated in a scrubber zone with a scrubber liquid-electrolyte comprising pollutant degrading metal ions or complexed with inert metal ions and degraded either in an electrolyzer zone or in both the scrubber and electrolyzer zones where spent scrubber liquid-electrolyte is regenerated for further cleaning.

Abstract: A circular connector for a plug-type connection to a mating connector which uses complementary locking means that are engaged and disengaged by rotation. Helical locking grooves are provided which have a bayonet detent space extending in an axial direction and an adjacent detent space extending in the peripheral direction. The detent space is defined by limiting means. Complementary noses on the mating connector are movable by rotation along the grooves into the detent spaces to lock the connectors.

Abstract: A multi-color liquid crystal display has a one-dimensional or two-dimensional array of at least one display cell, with a plurality of different liquid crystal host/guest dichroic dye compositions in each cell. Each of the different liquid crystal compositions may be provided within separate microcapsules, with the totality of micro-capsules being blended to provide the total composition filling the cell volume or dielectric spacers may be utilized to divide the volume of each display cell into a like plurality of subvolumes, each containing a different liquid crystal material. Liquid crystal hosts of substantially-constant or variable dielectric anisotropy magnitude and polarity are selected to cause different ones of the plurality of compositions within a cell to switch between transmission and absorption of various visible-wavelengths regions as the frequency and amplitude of an electric field within the cell is varied by control electronics of a display system.

Abstract: A golf club head (12) for a putter or chipper having a sighting device (16, 50, 44, 45) by which the golfer may easily align the club head to maintain its horizontal plane (31) parallel with the putting surface. The sole plate of the club head (12) is relieved by including two ribs (21, 22) extending from club face portion (13) to the rear of the club head to minimize dragging and scuffing on the grass of the putting surface during a stroke. Recesses (24) in the relieved areas are adapted to receive selectable size weights (26) which permit the weight of the club head to be adjusted to suit the individual and to also balance the head or to vary the heel-to-toe weight ratio. One golf club head (60) has a face (63, 70) having a plurality of deep vertical grooves (64, 72) therein between 1/32 and 1/8 inch wide, spaced by ribs (65, 71) to reduce the impact area of a golf ball with the golf club face (63, 70) to reduce back-spin and skidding of the golf ball.

Abstract: A fused station protector is disclosed wherein the fuse links have precisely controlled fusing characteristics. A shrink away foam element (28) encloses a portion of the fuse link (26) to provide a potential hot spot for slight current excesses. The remainder of the fuse link is in contact with arc quenching material (27) for extinguishing potential power arcs. Thus, the protector provides a precise fusing characteristic for slight current excesses and arc quenching capability for severe current excesses.

Abstract: A system employing packet switching techniques wherein time delays are reduced sufficiently to permit data and voice signals to be processed interchangeably in a common communications system wherein TDM signals are transformed into packet signals and packet signals are transformed into TDM signals, both transformations taking place with suitably minimized delays.

Abstract: A golf club head apparatus having a body of predetermined shape having a face, sole, top and rear sides and a hosel therein for the attachment of the shaft. One or more turning air vanes of predetermined shape are attached to the golf club head body for directing the flow of air in a predetermined pattern thereby. Each air vane is attached to the body in a predetermined spaced relationship to allow the flow of air around the air vane and between the air vane and the body to alter the aerodynamic characteristics of a golf club.

Abstract: A golf club head for a putter or the like having a sighting device by which the golfer may easily align the club head to maintain its horizontal plane parallel with the putting surface. The sighting device is a cylindrical cavity in the club head immediately behind the point on the club face at which the ball is struck. A light colored spot is concentrically disposed on the lower closed end of the cavity. A transparent disc is disposed over the upper open end of the cavity and has a concentric dark spot concentric therewith. The golfer establishes a vertical line of sight with respect to the ball and adjusts the plane of the club head to cause the lower spot to be in coincidence with the upper spot. The sole plate of the club head is relieved to the rear of the club face to minimize dragging and scuffing on the grass of the putting surface during a stroke.

The sighting device is a cylindrical cavity in the club head immediately behind the point on the club face at which the ball is struck. A light colored spot surrounded by a dark area is concentrically disposed on the lower closed end of the cavity. A transparent lens, which may include a convex or concave surface, is disposed over the upper open end of the cavity and has a concentric dark spot concentric therewith. The golfer establishes a vertical line of sight with respect to the ball and adjusts the plane of the club head to cause the lower spot to be in coincidence with the upper spot. The sole plate of the club head is relieved to the rear of the club face to minimize dragging and scuffing on the grass of the putting surface during a stroke.

Abstract: Apparatus for the electrical protection of communication circuits includes an insulative base (e.g., 13) having a line terminal (e.g., 3) and a station terminal (e.g., 1). A fuse wire (e.g., 2) is enclosed within a cavity (e.g., 21) within the base (e.g., 13). The fuse wire (e.g., 2) is connected in series between the line terminal (e.g., 3) and the station terminal (e.g., 1). The cavity (e.g., 21) is filled with an arc-extinguishing material (e.g., 22) to prevent a power arc when the fuse wire (e.g., 2) melts.
