Abstract: An indoor air purifier has a container with a layer of soil supported above a lower air plenum. Room air is drawn downwardly through the layer of soil and discharged from the plenum back into the room. Contaminant gases in the air are adsorbed in the soil and metabolized by microorganisms, producing carbon dioxide and water, and substantially reducing noxious and toxic materials in the air. The soil may be divided into two layers, and the air purifier operated in either of two modes. During normal operation, air is drawn through both layers of soil for removal of particles and destruction of contaminants by micro­organisms. Alternatively, air may be drawn through only one layer of soil at a substantially higher flow rate for removing particulate materials. Plants may be grown in the upper portion of the soil to aid in air purification and to provide an attractive room decor.

Abstract: A latching mechanism for forceps (10) including first latch portion (30) on one forcep handle (16) and a second latch portion (60) on the other forceps handle (22) and a bias spring (23,80,82) for placing the handles (16,22), and thus the jaws (14,20), in a first predetermined spacing. The first latch portion (30) has a cam surface (38), a shelf (40) and a slot (42). The second latch portion (60) has a transverse projection (66) which engages the cam surface (38) as the handles (16, 22) close and then engages the shelf (40) and upon further closing of the handles (16, 22) and then springs through the slot (42) to disengage the latching mechanism (30, 60) and return the handles (16, 22) to the original position controlled by the bias spring (23,80,82). The first position allows a surgical assistant to load an aneurysm clip (26) into the jaws (14,20) of the forceps (10). The second predetermined position allows the surgical assistant to partially close the handles (16, 22) sufficient to hold the aneurysm clip (26) firmly in place. The surgeon then takes the forceps (10)  and inserts the aneurysm clip (26) by further closing the handles (16; 22) and releases the latching mechanism (30,60) by relaxing the grip.

Abstract: Apparatus for producing tufted textile goods employs a plurality of hollow needles (10) which serve as backing openers, the backing openers being carried on a widthwise extending member which is reciprocated in a vertical direction to cause the backing openers to penetrate a backing (12). Yarn (92) is transported pneumatically through the backing openers and implanted into the backing as yarn tufts (14), the backing being shifted in the transverse direction by an amount corresponding to the spacing between adjacent backing openers in order to implant a transverse row of tufts. A knife blade (120) is associated with each backing opener (10) and positioned on the opposite side of the backing so as to engage the flat angled surface of the backing opener which forms its pointed tip. The angled surface is formed with an upwardly and inwardly extending slot which serves to capture and center yarn exiting the opening in the angle surface, and which provides a sharp edge which cooperates with the blade for cutting the yarn.

The block copolymers (B) employed contain from 10 to 85 % by weight of vinylaromatic units and from 15 to 90 % by weight of diene units. The block copolymers (B) may also have been partially hydrogenated, epoxidised or grafted. The preferred lactam is  epsilon -caprolactam. Lactam melts of increased viscosity are particularly suitable for accepting reinforcing substances and fillers (D) and for the preparation of filled casting polyamides. Also claimed are the use of lactam melts thickened in this way and in particular containing fillers/reinforcing substances in a process for the preparation of polyamides, and corresponding polyamide mouldings, in particular by the anionically activated casting process.
