摘要： A resilient support column for height-adjustable chairs or the like includes a piston-and-cylinder type pneumatic spring that is installable in and removable from the column by means of a retaining sleeve structure carried by the spring. The retaining sleeve is connected to the column through a threaded connection that permits quick one-step insertion of the combined sleeve-spring unit into the column, while thereafter affording the advantage of threaded adjustment within the column or threaded removal therefrom. A simple mechanical fastener holds the retaining sleeve in place on the pneumatic spring during shipment and/or assembly.

摘要： A socket assembly for a ball and socket coupling comprises a socket body having a ball-receiving socket which includes a cylindrical portion. A pair of slots extend through the socket body and open into the cylindrical portion at locations diametrically opposite each other and outwardlyfrom the seated position of the ball. Each slot has a flat surface which generally faces the seated position of the ball and converges inwardly toward the axis of the cylindrical portion of the socket, thus to lie obliquely to the axis of the cylindrical portion. A generally C-shaped spring clip wraps around the socket body. The clip has opposed end portions which extend through the slots and part way into the socket far enough to engage the neck of the ball component. The end portions of the clip are oriented generally obliquely to the axis of the socket. The socket body has a pair of external flat surfaces which underlie the clip, and the clip has flat portions which engage the flat faces of the socket body to keep the clip from turning out of proper position to permit the socket assembly to be pressed onto the ball component.

摘要： Apparatus for adjusting the spatial relationship between the bottom and the bade of a chair which may be subjected to seven mechanical stress, as in the case of a vehicle crash, the seat and the back being operatively connected respectively to two oppositely threaded portions of a rotatable shaft which is adapted to be routed in one direction or the other to produce the desired change in spatial relationship, the arrangement providing the combination of exceptional strength in the event of a crash and reduced cost. The operative connection between the chair parts and the shaft includes two non-rotatable parts engaged respectively with the oppositely threaded shaft portions so as to move in and out with respect to the shaft as the latter is rotated, and a housing which permits those parts to thus move while preventing their motion.

摘要： A ring laser gyroscope detector lens system for mounting on a ring laser gyroscope body having a resonant cavity. The ring laser gyroscope body has CW and CCW counterpropagating light beams propagating in a plane normal to the rate input axis of the ring laser gyroscope. The ring laser gyroscope detector lens system comprises a means for extracting a component of each of the CW and a CCW light beams from the cavity and for providing extracted CW and CCW beams. A means for combining the extracted CW and CCW beams to form an interference light source receives the extracted light. A planar array of detector element receives light from an objective lens means responsive to the interference light source. The objective lens means is typically a cylindrical lens that forms an interference light source pattern on the planar array of detector elements. A bias and amplification means is provided for conditioning each of the detectors in the array to be independently responsive to incident light intensity. The amplification means is further characterized to provide a detector output signal for each respective detector in response to the incident light intensity penetrating a predetermined threshold. The phase relationship between the detector output signals and the repetition rate of the detector output signals characterize the rotational polarity and rotational rate of the ring laser gyroscope body on the input axis.
