Title: Method of and apparatus for wrapping the raw edge of a  travelling web
IPC: B29C63/00
Filed: 1971-08-05
Abstract: 1353077 Making hollow-ware; jointing AMERICAN CAN CO 5 Aug 1971 [22 Jan 1971] 36941/71 Headings B3A and B3V [Also in Division B5] Thermoplastics tape is wrapped about a side edge of a moving web by applying the tape to one face of the web so as to overlap the side edge, wrapping it around the edge to form a U-section and pressing the tape so that it adheres to the web. A web of fibre, plastics or metallic material or laminates thereof may be wrapped about one side edge with a tape of polyethylene or polyester resin which may be effectively bonded to the web to produce stock from which cemented lap-seamed can bodies may be formed. An adhesive or an adhesion promotor may be used. Apparatus for performing the method comprises rolls 22, 24 about which the web 10 passes in a Z-path to curl the tape 16 first transversely and then back into the plane of the web. A jet 28 of hot air or, Fig. 6 (not shown), a fence (32) may assist the wrapping operation. The wrapped web may feed on to body making equipment. The web may be preheated and the tape may come direct from an extrusion head.

Title: Improved plunger and die mechanism for forming trays
IPC: B31B50/00
Filed: 1963-09-20
Abstract: 990,148. Box erecting machines. CONTAINER A.G. PAGENT-VERWERTUNGSGESELLSCHAFT. Sept. 20, 1963 [Sept. 20, 1962], No. 37024/63. Heading B5D. A blank 1 having a rectangular base portion, a wall hinged to each edge thereof, and a panel secured to the base portion so that the tray formed from the blank will have a rim is fed by a plunger 2 into a die, the die comprising stops 17, 18 extending across part of its mouth and guides 15, 16 extending along the walls of the die from which the stops project, which guides have gaps therein to receive the rim. The stops engage the rim as shown in Fig. 2 and one guide is moved towards the other to bend up the first pair of opposite walls of the blank and comer extensions which project from the second pair of walls. Jaws 32, 33 which extend along the other two walls of the die are also operated by means of a linkage connecting them with the movable guide to bend up the second pair of walls of the blank and finally when the movable guide has completed its stroke a switch is closed which operates folders 36, 37 to fold over panels extending from the first pair of walls to enclose the corner extensions. In a modification the blank 1 does not have a panel secured to its base portion and the guides 15, 16 are not gapped whereby a rimless tray is formed. The walls of the tray may be bent up perpendicularly to the base or to any other desired angle. In another embodiment both guides are movable.

When not in use the casing is covered by a table top E.
Patent GB-1445200-A (GB)
Title: Dryer control system and method
IPC: F26B25/22
Filed: 1973-08-06
Abstract: 1445200 Automatic electric control INDUSTRIAL NUCLEONICS CORP 6 Aug 1973 [14 Aug 1972] 37279/73 Heading G3N A dryer is controlled so that the moisture content of material passing through it is maintained constant during transitional periods when the dryer load is changing. A control signal is formed by combining a time-weighted predetermined drying rate trajectory with an oppositely time-weighted measured parameter of the dryer. As shown, tobacco is passed through a weigher 12, dryer 13 and cooler 14 to a storage bin 15. The dryer temperature is sensed by a transducer 25 and controlled by the operation of a steam valve 18 responsive to a PID controller 52 with a set point determined by a D-A converter 53 in a computer unit 21. The input to converter 53 depends on the position of a switch 50 which is set automatically to start-up, run, shut-down or precondition by a logic circuit 33 responsive to the outputs of moisture sensors 23, 24 which produce zero signals when no tobacco is present in the weigher 12 or on a conveyer 16 respectively. The sensed moisture content of the incoming tobacco, and the weight detected by sensor 22, provide a signal indicative of the required drying rate, and this signal and a stored trajectory signal in a memory 71 are oppositely weighted and used to feed a composite signal to converter 53 during start-up and shut-down periods. The weighting factor is proportional to the time elapsed since the start of the relevant transition period, and is provided by a clock oscillator 73 with an associated counter 72. The use of weighted signals prevents over or under-drying during transition periods and avoids rapid changes in control signal magnitudes.

The finger is so curved that it engages several of the rollers and, in the event of wear, the free end does not touch the chain. The spring may consist of one leaf or of more than two leaves as disclosed, for example, in Specification 445,152.

There is a hood and heat shield 8 which has a skirt seal 31 sealing with the ladle 1, and means 32, 30 for supplying and discharging an inert or reducing gas. The stirrer shafts 13, bridge pieces 12 and (if of metal) stirring members 11 have passages for the circulation of cooling water. The stirring members may be made of graphite or refractory material such as zirconia or a combination thereof (45, 46) Fig.8 (not shown); the hollow stirring shaft 13 may accommodate an oxygen lance (41). Alternatively the stirring members may be metal vanes 47, Fig.10. A hopper 37 may supply a granular treating agent. In operation the stirring members are positioned so that they stir the iron in the region of the iron/slag interface, the sense of rotation of the stirrers being periodically reversed. Examples relate to desulphurization, dephosphorization, and the incorporation of ferrosilicon.

Read wire R 1  links the first row of cores (22, 20) then the row vertically below (24, 26) and then down to link successively the corresponding rows in the 5th, 6th and in the (4n-3)th and (4n-2)th planes, where 4n does not exceed the number of planes of cores. Read wire R 2  links the second row of cores in the planes in the same way and a second plurality of read wires link the rows of cores in the 3rd, 4th, 4nth and (4n-1)th planes. A first plurality of inhibit wires I 1 , I 2 , &c. link the first and second &c. rows of cores in the odd-numbered planes and a second plurality of inhibit wires I 3 , I 4  link the corresponding rows of cores in the evennumbered planes. The cores in the first, fourth, fifth, (4n-3)th and 4nth planes are all parallel in a given direction while the cores in the remaining planes are set parallel to one another in a different direction. The arrangement is such that each core is threaded by a first coincidence current wire, a second coincidence current wire and a read-out wire which, in combination, do not thread any other core. Also, each read-out wire and an associated coincidence current wire thread in the same current direction a number of cores substantially equal to the number of cores they thread in opposite current directions. In addition the relationship between current directions of any coincidence current wire and any inhibit wire with respect to the cores they thread in common is the same for all those cores.
