Title: Apparatus for packaging similarly shaped articles
IPC: B65B5/02
Filed: 1971-03-18
Abstract: 1381712 Packaging; trays P E ELFORD 19 June 1972 [18 March 1971] 7199/71 Headings B8C and B8P An apparatus for erecting a tray blank, Fig. 1, around an array of similarly shaped articles includes an arrangement for raising tabs 18-21 prior to the erection of wall portions 11, 13. In a first embodiment, Fig. 2, the articles, which may be cans, jars, bottles and packets, are pushed in to a tray blank positioned on a vertically reciprocable platform 36 and then the platform 36 is lowered so that four projections 22-25 raise the tabs 18-21 before the wall portions 11, 13 are raised by plates 80. In a second embodiment (Fig. 4), the articles and the blank are placed on a stationary platform (36) and pivotable erecting plates (104, 106), each having pairs of projections (112, 114) for engaging the tabs 18-21, effect the raising of the tabs 18-21 and then the erection of the wall portions 11, 13. In both embodiments the package is completed by pushing the partially formed package from the platform 36 on to a further platform 82 and into a channel defined by strips 86, by means of a ram 74. End portions 26-29 of the wall portions 11, 13 are folded inwardly and around the tabs 18-21 by projections 78 on the face of the ram 74 and by the ends of the strips 86. The still unerected wall portions 10, 12 extend through opposed slots 88 and have blobs of quick-setting adhesive applied thereto by ball applicators such as 92, 94. The wall portions 10, 12 are then raised by movement over ramps 96 and pressed into contact with the end portions 26-29 by opposed pairs of rollers 100, 102. The articles to be packed are supplied by a continuous conveyer belt to a matrix (46<SP>1</SP>, Fig. 3), from which they are pushed by a ram (54, Fig. 3), on to a dead plate 42. The matrix (46<SP>1</SP>) may be vertically reciprocable. The blanks 62 may be fed to the platform 36 manually or by a pneumatic feeder 64 which grips by suction the lowermost blank in a magazine, pivots in the direction of the arrow, moves downwards and drops the blank on to a conveyer belt 68. The operation of the apparatus is synchronized and interlock means prevent operation of the various components until the conditions for their operation have been attained. The package may be transferred to a shrink-wrap apparatus.

[Class 100 (ii).] Tripping-arrangements.-In connection with a sheet-feeding device fitted with front stops E which are depressed when the front of the sheet is registered, a trip lever A is pivoted near the stops E and is actuated to trip the machine if the sheet is fed beyond the stops E by the time these are raised to registering position. The lever A is fitted with an adjustable stud C which is raised by the crumpled sheet and the sheet guide D when the sheet has passed beyond the stops E, and the lever A is thus moved anticlockwise to bring a knife edge F into engagement with a trip catch G on an arm G<1> fitted to the usual tripping motion of the machine. This arm in the normal working of the machine moves to the position shown in dotted lines, but when it is arrested by the lever A the machine is tripped. A movable rod may replace the oscillating arm G<1>. The lever A is normally raised by a spring K into contact with a screw J which can be adjusted so as to permit its normal position to be varied. The device may be used with front stops which are raised to permit of the feed.

Abstract: 1434701 Colouring anodized aluminium electrolytically ALCAN RESEARCH & DEVELOPMENT Ltd 19 Feb 1975 [20 Feb 1974] 7807/74 Heading C7B In the continuous electrolytic coloration of anodized Al strip using an acid electrolyte bath containing a manganate, tellurite or selenite or at least one salt of Co, Cu, Ni, Fe, Ag, Sn, Cr or Pb, by passing current between the strip and an electrode immersed in the bath and facing an anodized surface of the strip, the current is introduced into the strip through an unanodized area thereof. In Fig. 1, the strip is D.C. anodized (in e.g. H 2 SO 4 , oxalic acid or chromic acid) in cell 1 which contains immersed anodic and cathodic electrodes 4. After washing at 6, the strip is A.C. coloured in cell 7 using immersed electrodes 8, which connect to the strip via A.C. supply 9 and the anodizing anodes 4. Conductor 10 may either be replaced by variable resistance to give variable superimposed D.C. in the colouring bath, or may be removed, so removing the superimposed D.C. An alternative arrangement uses an external contact roller before the anodizing bath to introduce both the A.C. and D.C. Instead of superimposed D.C., an asymmetrical A.C. supply may be used. When the Al is anodized on one side only, either the process can be conducted on an already anodized strip, or the current can be introduced from an anodic sliding block contact, e.g. of graphite, in the anodizing bath. Electrolytes  exemplified contain (1) NiSO 4 , (NH 4 ) 2 SO 4 , MgSO 4  and H 3 BO 3  at pH 5À7 or (2) CuSO 4 , MgSO 4  and H 2 SO 4  at pH 1À3.

The pilot valve is operated against a spring by a Bowden wire from the driver's seat through a lever D which coacts with an adjustable screw for determining the valve lift. A third valve may be incorporated in the valve body for controlling the supply of steam to the cylinder jackets as described in Specification 565,552, [Group XXVI].

Refrigerating, absorption machines for.-In an air cooled condenser for machines of the inert .gas type, a part of the condenser is effective, only when excessive quantities of vapour are to be dealt with. The liquefied refrigerant flows through the condenser in the presence of some of the inert gas that has passed over from the evaporator-absorber side. In the apparatus shown, vapour rises through the pipe 42 from the generator (not shown) and is rectified and partly condensed in an inclined gilled tubs 43, as described in Specification 327,189, and flows through a conduit 53 into the middle of a lower inclined, gilled tube 54. In normal working only the left hand part of the lower tube is effective for condensing vapour flowing from the upper tube, and the right hand part, which has a cooling capacity at least equal to the left hand part, comes into use for abnormal conditions. Any inert gas passed over into the condenser collects in the outlet end 56 of the lower tube, and thus the liquefied refrigerant is air cooled in an atmosphere of inert gas. A gas vent 60 returns surplus inert gas to the evaporator-absorber side.
