Abstract: Benzoylamides of the general formula (I) are described as herbicides. In this formula (I), B, X1 and X2 represent N, O or S(O)n. R, Ra, Rb and Rx represent radicals such as hydrogen, halogen, (C1-C6)-alkyl, halo-(C1-C6)-alkyl, (C1-C6)-alkyloxy and cyano.

Abstract: A chair seat tilting mechanism comprises a support for mounting to a chair spindle and a lever arm pivotally mounted at a pivot to the support, which lever arm is for mounting to a chair seat. A link arm is pivotally mounted at a pivot to the support and has a cam with a camming end positioned between the lever arm pivot mount and the link arm pivot mount. An extension of the link arm mounts to a chair back such that when a chair occupant leaning back on the chair back, the link arm pivots about the link arm pivot causing the cam to cam lever arm so that it pivots about its own pivot with the support. This results in the chair seat tilting forwardly.

Abstract: A chair armrest adjustment mechanism for an armrest is disclosed. The armrest adjustment mechanism includes a first member, an upstanding second member for mounting to an armrest support member, and a third member having attachment means for fixedly attaching the third member to an armrest pad. The third member and the second member have a pin and slot arrangement to limit the rotational movement of the third member. The first member is pivotally mounted to the second member via a pin such spring cups between the first member and the second member at either side of the pin for biasing the first member to a level orientation with respect to the second member.

Abstract: This invention discloses a novel cover for use with legs of a chair base, particularly for use with chairs having a plurality of legs extending radially outwardly from a central column. The cover is adapted to surround and cover one leg and comprises a cover portion, a first end portion to cover the end of the leg, spacing means to space the cover portion from the top surface of the leg, and retaining means to releasably retain the cover to the leg. A retaining ring is also provided and adapted to retain the second ends of all of the covers in the desired position. Securing means may also be provided to secure the cover to the leg to prevent longitudinal movement once the cover is in place. The use of the cover allows the user to select the desired look of any shape and color and also protects the chair legs and prevents damage thereof. The use of the cover has reduced the cost of manufacturing a chair since, with the cover, the legs may be unfinished and need not be replaced over the life of the chair.

Abstract: A chair leg and a protective cap therefor. The cap is adapted to fit over and be secured to the end portion of the chair leg. The cap has a small protrusion on the inside top surface which fits into and is secured by an aperture in the upper surface of the chair leg. The cap has also an aperture in the bottom surface which fits over and is secured by a portion of the socket which extends below the plane of the lower surface of the end portion of the chair leg. This new structure reduces significantly the cost of production by eliminating the need to grind and buff the end portion of the chair leg yet produces a smooth, safe and acceptable end for the chair leg.

Abstract: A novel base portion for a tiltable chair. The base portion comprises a chair control adapted to control the tilting of the chair, a threaded cylindrical post secured to the chair control and extending vertically downward, an outer, vertically aligned tubular sleeve around the cylindrical post, a bell assembly mounted on the cylindrical post above the tubular sleeve and adapted to control the height of the chair, an alignment means adapted to align the tubular sleeve in a vertical position relative to the cylindrical post with the alignment means mounted on the cylindrical post inside the tubular sleeve, and a plurality of radially extending legs adapted to support the chair with their inner ends secured to the alignment means.

Abstract: This invention discloses a novel chair control for use with a tiltable stenographer's chair. It discloses a compact and improved biasing means to control the movement of the movable frame member, this biasing means being a U-shaped bolt with two helical springs thereon, inserted from the front of the chair control about which the movable frame member pivots. This new biasing means eliminates unsightly handwheels and associated mechanisms hanging down from the control and provides an extremely compact device. Also disclosed is a wrench permanently carried by the biasing means for adjustment thereof, the wrench folding out of the way after use. A second biasing means is disclosed which depends from the plate affixed to the seat and eliminates unsightly mechanisms from the front of the control.
