Abstract: 1372209 Packaging bottles OWENS-ILLINOIS Inc 21 Dec 1971 [21 Dec 1970] 59344/71 Heading B8C Bottles C are segregated into clusters by star wheels 22, an endless elastic band is positioned by a head 26 around each cluster, and finally an elastic carrier strip having an opening for each bottle top and a pair of finger holes is placed by a head 31 over each cluster. Brushes 21a drag the bottles as they leave the star wheels so that they are located against flights 21b on a convever 21. The heads 26 and 31 are mounted on carriages 25 and 30 which are reciprocated along the cluster conveyer 21. Each head has three sub-heads on each side and is rotatable through 180 degrees so that while the sub-heads on one side apply the bands or strips to three adjacent clusters the sub-heads on the other side are reloaded. Three flat tubular webs P are fed to the carriage 25 where oscillatable roller knives cut the webs into bands. A shaft (91, Figs. 4-9, not shown) carrying vacuum heads lifts three bands and positions them adjacent vacuum heads on a second shaft. On the shafts moving apart each band is caused to take up a rectangular shape. The head is then lowered causing fingers 120 on three sub-heads to enter the three bands, and bands on the other sub-heads to be placed around three clusters on the conveyer. Each finger is pivotable about an eccentric vertical axis to grip or release a band. Three webs E of carrier strips are fed to head 31 where each sub-head has plungers engageable in the bottle top openings and radially movable outwardly to grip the strip. Downwardly movement of the head to grip the strips causes a slight backwards motion of the feed mechanism of the webs E to tear the gripped strips from the rest of the webs along weakened lines. When a strip is lowered on to a cluster the plungers which are resiliently mounted seat on to bottle tops and on further downward movement of the head stripper fingers push the strip off the plungers and on to the bottle tops.

Patent GB-2033931-A (GB)
Title: Weft knitting
IPC: D04B15/54
Filed: 1978-11-03
Abstract: Two yarns are fed together to be knitted separately at the same feeder of a weft knitting machine of the double jersey kind (or other machine that has intercalating sets of needles). The yarns can be knitted on needle groups selected from either set (e.g. odd dial and even cylinder needles, or odd dial and even dial needles) by guiding the yarns to their needles from positions downstream of the point where the needles begin to rise to the knit position. The yarns can be fed from in front of the needles or behind the needles, and the groups of needles may be separated by delayed timing in the cam. Productivity is improved because all needles can knit at every feeder on many fabric constructions; and if desired, two separate single jersey fabrics can be made on a double jersey machine. <IMAGE>

Title: Solenoid-controlled Safety Valve for Wells
IPC: H01F7/123
Filed: 1979-05-10
Abstract: A tandem solenoid fail-safe sub- surface safety cut-off valve for fluid wells is controllable from the surface and suitable for installation at substantially greater depths than prior constructions. The valve assembly may be installable and retrievable either via wire line or tubing techniques and utilizes tandem electromagnetic means to operate either a flapper 31 or a ball cut-off valve. The solenoid coils 11 embrace a landing nipple portion 2 of the tubing string 3 or the tubing string itself and hold either type of cut-off valve open against spring pressure only so long as the coils are energized thereby providing surface control of the safety cut-off valve normally and assurance of closing of this valve by energy stored in spring means 30 in the event of power failure through accident or some catastrophe as well as automatic closure if flow velocity increases beyond a predetermined safe value. The tandem solenoids provide abundant operating energy while utilizing a minimum of radial space between the casing 4 and the tubing string 3. <IMAGE>
