Abstract: A constant false alarm rate (CFAR) circuit uses three windows for calculating mean level thresholds. In addition to a lead window and a lag window each separated from a cell of interest by a predetermined number of cells, a straddle window is used which includes the cell of interest. Each of the lead, lag and straddle windows are subjected to editing to remove three adjacent cells including the cell with the highest power level. The remaining cells are used to calculate a mean level threshold for each of the three windows. The largest of the three mean level thresholds is used, unless it is derived from the straddle window and it is significantly larger than the largest of the mean level thresholds derived from the lead and lag windows. In addition, use of the mean level threshold derived from the straddle window may be excluded for range cells associated with one or more range and azimuth.

Abstract: The toe end of a hose blank has a looper line bead and is toe closed by movement past a seamer along a seam line located by reference to the head, the blank being mounted on a toe closer carrier of conventional form. Opposed blades of the carrier execute a forward movement to pass the beaded end of the blank through a space between two open jaws of a positioning device; the jaws thereafter close and by drawing the blank backwards the bead is brought against the jaws, which are at a pre-set location relative to the seamer and the toe end is thereby positioned ready for seaming. The toe end is then conveyed to and past the seamer by a transport belt, the positioning established by the jaws being maintained during conveyance of the blank to the seamer.

Abstract: A radar having a multiplicity of receive beams stacked in elevation and a target height extractor especially for use therein are disclosed. In operation, a set of range sweeps corresponding to an azimuth scan of the stacked receive beams across a detected target is established. A range cell interval corresponding to the detected target is estimated for each range sweep of the set. A target range measurement is computed from a set of estimated range intervals. Only the radar receive beam echo information corresponding to the estimated range cell interval for each range sweep of the established set is used by the height extractor to compute a corresponding set of elevation angles. A target elevation angle is formed as the weighted average of this computed set. Only one height computation is performed for each established set of range sweeps based on a function of factors including the computed target elevation angle and computed range measurement of the corresponding established set of range sweeps.

Abstract: Transfer of garments, having limp portions, from one machine (L) to another machine (T) the needs of which demand that the limp portions are separate for delivery to separate receiving members therefor, is accomplished while the garments are moving in the direction of the receiving machine (T). The limp portions of the moving garment are draped over a guide rail (28); a second guide rail (30) is encountered by the limp portions, this rail being positioned to interpose itself between the advancing limp portions, with the result that one limp portion becomes draped over each rail.

Abstract: Toe closing socks first involves stretching them flat on a carrier, then one of the resulting confronting layers of fabric is effectively held substantially immobile by a fabric-holding device and the other layer is displaced longitudinally relative thereto by a movable displacing means brought into engagement therewith. Maintaining the layers mutually displaced, for example by clamping them to one another, they are conveyed past a sewing machine and seamed. By seaming the layers together while they are mutually displaced, the seam will adopt an overfoot or underfoot position in the finished sock due to readjustment of the fabric and the return of the layers to their normal relaxed relative dispositions.

Abstract: Hosiery manufacturing equipment comprises a line closer (L) and a toe closer (T) which are linked by a hose transfer mechanism (M) consisting of two conveyors (30, 31) which overlap in a region between the closers (L, T). The conveyors have respective hose holders (39, 40) which coact in the overlap region so that hose carried by the first holder (39) are stripped therefrom and taken over by the second holder (40) which ultimately mounts the hose on the toe closer (T); the first holder is responsible for stripping the hose from the line closer (L) and for rotating the hose through a predetermined angle which is related to a difference in angular attitude between respective hose supports (10, 16) of the two closers (L, T).

Abstract: A hosiery toe closer has a hollow tubular carrier, to which suction is applied for everting hosiery, and an unloading mechanism for dispensing hose in an everted state on a table or tray. The unloading mechanism is a carriage reciprocally-movable forwardly of the carrier and the carriage supports at least one hose holder engageable with a welt of a hose on the carrier, so that as the carriage moves forwardly, it pulls the hose welt along the carrier while simultaneously the hose toe is sucked into the carrier; continued movement of the carriage pulls the hose out of the carrier and discharges it in a straight, everted condition.

Abstract: Hosiery toe closing and boarding apparatus has a pair of heatable boarding forms to which hose are fed by a reciprocally-acting transfer mechanism from carriers of a known toe closing machine. The boarding forms are mounted on a turret to move between hose-receiving and hose-discharging positions respectively associated with wind-on and wind-off rollers. At their ends remote from the toe closing machine the boarding forms are interconnected by a hinge with a rotatably-drivable hinge pin for causing one form to swing into a superposed, registered position over the other form immediately prior to discharge of the hose from the boarding apparatus.

Abstract: For toe seaming hosiery knitted with reinforced and/or shaped heels, automatic toe closer has one or more hose carriers, a sewing machine and a clamping means movable for conveying a toe end portion of a hose on a carrier past the sewing machine for toe closing. The toe closer has a heel positioner comprising a rotationally-driven roller mounted for movement into and out of frictional engagement with a hose on the carrier, rotation of the roller in contact with the hose causing a rotation of the latter about the carrier until a mark on the hose aligns with a photosensor responsible, when alignment occurs, for causing disengagement of the roller from the hose leaving the latter in a properly adjusted attitude on the carrier in readiness for seaming.

Abstract: A toe closer has a plurality of elongated carriers for supporting hose for seaming, a sewing machine to seam their toes and a clamp mechanism for sequentially conveying toe ends past the sewing machine. The carriers move continuously around a closed path traversing a straight section of the path directly opposite the clamp mechanism. The clamp mechanism includes a stationary worktable associated with the sewing machine, and a carriage movable to and fro carrying a movable worktable section and a coacting, intermittently movable clamping belt which is supported in a belt carrier atop the carriage. Drive means move the carriage towards the sewing machine in unison with movement of each carrier along the straight section of the path while the toe end of a hose on each carrier is fed into the clamp mechanism; thereafter the belt is set in motion to slide the toe end from table section to table and across the latter in front of the sewing machine for the latter to produce the required seam.
