A closure for containers consists of a container mouthpiece and cap to either of which is connected a hollow stopper which has at least one opening for filling the container and which can be pressed in to close the filling opening. In Fig. 1 the container mouthpiece 1 carries a pin 2, held by stays 3, which co-operates with the bore 10 of a mouthpiece 8 carried by a screw-cap 4. Filling is effected through a hollow stopper 12 carried by a filling head 13, the material flowing through an annular space 11, and on completion of filling the stopper 12 is pressed into the space 11 to close the filling opening. To extract the filling, cap 4 is screwed off until pin 2 clears the mouth of bore 10. In a modification, Fig. 4 (not shown), the stopper may be held by tear-off lugs before being pressed into the container neck. In Fig. 8 the container is filled through openings 75 in a stopper 73 when the stopper is projecting from the neck 71, the stopper being subsequently driven into the neck to close the openings 75. A dome 76 of the hollow stopper 73 rests fast in the bore 81 of the closure cap 79 and may be further gripped by the use of longitudinal ribs 81<SP>1</SP> in bore 81 so that dome 76 is removed with closure cap 79 to open the container. In a modification, Fig. 6, a pin 64 fixed inside the screw-cap 53 presses a thin plate 59 from the stopper mouth into the container and opens the stopper as the cap is screwed down. This plate could in another modification be held by a tear-off ring in the stopper dome. Specification 995,487 is referred to.

Abstract: 1344384 Transistor matrix store NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 19 April 1971 [27 Feb 1970] 23052/71 Heading G4C A transistor matrix has the bases of all transistors in a column coupled to a conductor 11, has the emitters of all transistors in a column coupled to a conductor 12 and has the collectors of all transistors in a row coupled to a conductor 10. The conductors 10, 11 are coupled to pulse sources 13, 22 respectively. To write a "1" pulses are applied to selected lines 10, 11 so that current flows from the base to the collector and minority carriers are stored at the base collector junction. To write a "0" conductor 10 is maintained at a high level and conductor 11 at a low level to discharge the minority carriers. To read, conductor 10 is maintained at a high level with conductor 12 at a low level. If a "1" is stored current flows and is detected by a special unit (Fig. 2, not shown) or by transistor 19 (Fig. 4) coupled to pulse source 21. Transistor 19 is used to rewrite the data back into a transistor 9 because the charge stored is dissipated on read out and the storage effect lasts for only tens of nano seconds.

Abstract: 1319601 Tufting machine yarn feed DEERING MILLIKEN RESEARCH CORP 13 May 1970 [13 May 1969] 23243/70 Heading D1G In a tufting machine in which yarn 40 is cyclically inserted as loops into a backing fabric (16) through reciprocable hollow needles (30) by compressed fluid, feed means for producing different loop heights in accordance with a pattern comprises central drive units 86 each including a plurality of concentric shafts 100, 114, 124 driven at different rates by transmission means 43 and selectively engageable by clutches 135, 146, 148 with drive shafts 140, of yarn feed modules arranged circumferentially about the central drive units. As shown, there are four modules around each shaft 140 and the concentric shafts of all the central drive units are driven at different rates. through chain and sprocket transmissions from different sized sprockets 62, 68, 74 on a common shaft. Gears 158, 162 and 182, which are rotatably mounted on each shaft 140 and mesh with gears 122, 112 and 132 respectively of the concentric shafts, selectively drive the shaft 140 through an over-running clutch 156 and magnetic clutches 148, 150 respectively. When either magnetic clutch is energised to rotate the shaft 140 at the corresponding rate the clutch 156 over-runs. Each shaft 140 rotates a pair of feed rolls 210, 212 which control the supply of yarn to one needle. The pairs of feed rolls in each vertical row are staggered (Fig. 2, not shown) to prevent interference with other yarns 40. Energisation of the clutches of each module may be controlled by a respective circuit including a photocell sensitive to the light passing through a belt (238) (Fig. 7, not shown) with transparent, opaque and partlytransparent portions or including a makebefore-break switch (302) with a double leaf switching element (326) controlled from a camshaft (286) (Fig. 8, not shown) or by a pattern chain (Fig. 12, not shown).

Title: Photographic contact printing apparatus
IPC: G03B27/22
Filed: 1948-09-03
Abstract: 657,325. Photographic contact-printing apparatus. GRIN TEN, L. P. F. VAN DER, GRINTEN, P. A. W. VAN DER, and GRINTEN, K. J. J. VAN DER, (trading as CHEMISCHE FABRIEK L. VAN DER GRINTEN). Sept. 3, 1948, No. 23291. Convention date, Sept. 3, 1947. [Class 98 (ii)] The apparatus comprises a translucent printing cylinder, which is mounted to rotate relatively to a central light source and over which the original passes for copying, wherein air ducts having openings on the outer surface of the cylinder along a generating line are connected to an air-pressure control system capable of creating a variation in air pressure at the duct openings, and delivery means adjacent said generating line feed the original to the cylinder, whereby the leading edge of the original may alternatively be held close to the cylinder or blown away from it. Preferably, feeding means operable in synchronism with rotation of the cylinder feed the original against a locating shoulder on the cylinder, and the variation in air-pressure from suction to blowing is also synchronised with this rotation. As shown, a light-sensitive strip 3, e.g. of diazotype paper, is fed from a supply spool 4 around an undriven contact printing cylinder 1 beneath rollers 7, 11 by means of a draw-off roller 5, the spool 4 being braked at 16 to hold the strip taut, and may be cut off by a guillotine 13 controlled by rotation of the cylinder 1, the cut prints then being developed dried, and if desired, folded at 14 and stacked at 15. An original 10 is pushed along a tray as at 25 into the entry shoot 22 of the printer until it engages a stop 24 controlled by a light spring. A feed roller 26 carries a lug 27 which engages the original and moves it past the stop 24 so that it is located against a step 28 in the cylinder, the location being assisted by a suction device comprising a low pressure fixed chamber 18 and a row of air ducts 17 in the rotating cylinder. The original thus located is retained in position by the strip 3. When it is desired to remove the original, the pressure in the chamber is raised above atmospheric, so that as the ducts 17 come opposite the roller 11 the original is blown away from the cylinder and passes along a guide plate 19 from which it is directed by an air blast 20 into a tray 21. If only a single print of each of a series original is required, the change in pressure in the chamber 18 may be controlled by rotation of the cylinder 1, and a knife 13 may be operated in synchronism with rotation of the cylinder to cut the separate prints from the strip so that they are piled.up in order in the tray 15. Instead of a long strip of light-sensitive material 3, cut sheets may be. fed over the cylinder by an endless belt in synchronism with the originals under control of the cylinder rotation. Specification 501,103 is referred to.
