Title: Improvements in the means of forming cardboard and similar cartons or containers
IPC: B31B3/74
Filed: 1929-02-11
Abstract: 330,913. Ware, H. M. Feb. 11, 1929. Paper tubes.-A suitably shaped cardboard blank, located in a tray j, j<1> is formed into a tube for the production of a carton by feeding it to a conical &c. mandrel b, mounted on a pedestal a, and folding it therearound by a tool d consisting of a series of pairs of arcuate spring jaws d<3> adapted to engage with, and circumferentially conform to, the said mandrel. The tray is formed in two parts j, j<1> with the outer edge of the part j<1> further removed from the centre of the mandrel than the outer edge of the part j, so that the edge of the blank located in the part will overlap the edge located in the part f after operation of the folding tool d. The blank is gummed along the edge in the tray j<1> prior to application to the mandrel and is initially held against the same by a clamping bar c disposed below and centrally of the mandrel, while a joint-sealing pressure bar e, which may be heated, is disposed above the mandrel. The wrapping-tool d and pressure bar e are both connected to rams f, e<5> reciprocating within cylinders f<1>, e<1>, respectively, the rams being moved outwardly by fluid pressure controlled by valves g', e<4>, as shown, and returned by springs f<2>, e<8>. The valve g<1> is actuated by a foot-lever h, while movement of the valve e<4> is controlled by a trip f<3> on the tool d through the medium of pivoted rods e<6>, e<7> and valve rod e<9>. The tool d is also formed with a cam surface d<2> which operates a lever i to raise the clamping bar c. In operation, a blank is fed by hand to the tray j, j<1> and gummed. The foot-lever h is then depressed to admit fluid pressure to the cylinder f<1> and move the ram f and folding tool d upwardly. Before the tool d engages the blank however the cam d<2> thereon actuates the clamping bar c through the lever i. Continued movement of the folding tool causes the gummed edge of the blank to overlap the ungummed edge and also, by the opening of the valve e<4> by the trip f, movement of the ram e<5> and pressure bar e to seal the joint. When the joint is sealed sufficiently the foot-pedal is released and the valve g<1> consequently lowered to exhaust the cylinder f<1> and allow the spring f<2> to retract the folding tool, the downward movement of the latter operating the lever e' and valve e<4> to permit release of the pressure bar and the lever i to withdraw the clamping bar. The completed tube is then removed from the mandrel. The invention is also applicable to the making of tubes from blanks having waxed or similarly treated edges. Specification 16363/09 is referred to.

Title: Apparatus for the complete gasification of carbonaceous fuel
IPC: C10J3/00
Filed: 1921-02-08
Abstract: 179,643. Simpson, J. F. Feb. 8, 1921. Producers.-Apparatus for the complete gasification of carbonaceous fuel comprises a water-gas producer 1 preferably surmounted by a retort 2 and hopper 15, and having two regenerators 4, 6 so arranged that an up or down blow through the producer may be obtained. The air main 12<b> is divided and its two branches, controlled by valves 12, 12<a>, lead into blast pipes 10, 10<a> provided with stack valves 11, 11<a> and communicating with the regenerators 4, 6. The producer is in connection at its bottom and top ends with regenerators 4, 6 by pipes 3, 5 respectively. When valves 11, 12a are closed the air blast passes down through regenerator 4 up through the producer which is heated thereby and the resulting gases together with secondary air introduced through a pipe 9 pass up regenerator 6 which is thereby heated, the combustion products escaping by the stack valve 11<a>. The direction of the blow is then reversed by valve manipulation and when the fuel bed is heated sufficiently, steam Introduced by an inlet 7 ,is heated in the regenerator 4 and enters the producer at the bottom, the resultant water gas passing up through the retort, partly distilling the raw fuel and passing through a take-off pipe 17 to a wash-box 18 and leaving by an outlet 20. Liquid fuel may be admitted to the retort by a pipe 21. During the blow a portion of the gases may be passed up through the retort.

Title: Improvements in or relating to automatic and semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1929-02-12
Abstract: 329,028. Standard Telephones & Cables, Ltd., and Wright, E. P G. Feb. 1929. Automatic and semi-automatic exchange systems.-Trunk-offering distributors and connectors are controlled by apparatus connected in multiple to a group of similar switches and including a pair of marking switches on which the incoming digits are recorded. The distributors, connectors and marking switches are all of the single-motion type. Test distributor, Fig. 1. Upon seizure, relay IK energizes in series with relay 12, which cuts out its lower winding to mark the common apparatus and hence all the distributors engaged, while relay IK associates the common apparatus with the seized distributor. Line and release relays 11, 14 energize, and the first train of impulses are repeated to magnet ITC. Series relay 13 is operated during the train, and two-step relay 15 energizes fully at the end, transferring the impulse circuit to magnet IUC. Magnet S operates when relay 13 pulls up and advances the distributor until the position marked by the switch ITC is reached, when relay 16 energizes over wipers C, ITC1. Belay 15 connects up relay 19, which locks. Two-step relay 17 energizes fully at the end of the second train of impulses, and re-closes the circuit of magnet S, which operates until the position marked by the switch IUC is reached, when relay 18 energizes over wipers C, IUC1. Test relay IH is now connected to test wiper T in series with relay 19, and energizes provided the test connector is idle, locks, switches through and disconnects relay IK to release the common apparatus. Homing circuits are completed for the switches ITC, IUC when relay 14 falls back. If the test connector is engaged, relay 19 relapses and busy tone is connected up from wire BT. Test connector, Fig. 2. Upon seizure, relay 2K energizes in series with relay 22, and individual line and release relays 2A, 2B pull up. The successive trains of impulses are repeated to magnets 2TC, 2UC in series with relay 23, two-step relays 25, 27 being energized at the ends of the trains. Magnet 2S advances the connector successively to the positions marked by the switches 2TC, 2UC, and relays 26, 28 determine when these positions are reached. No test of the wanted line is made, and switching relay 2H energizes locally in series with relay 29, locks and disconnects relay 2K to release the common apparatus. The group-marking terminals in the connector are used for the first lines of the groups; thus if the test digit is 1, the marking- wipers 2UC1, 2TC1 are connected together.

Title: A method of and mechanism for automatically opening closed book signatures and the like
IPC: B65H5/30
Filed: 1932-02-17
Abstract: 396,816. Stitching book signatures. POLLAK, J. E., 20, Holborn, London.- (Brehmer, Geb. ; Plagwitz, Leipsic, Germany.) Feb. 17, 1932, No. 4711. [Classes 89 (iii) and 112.] In feeding folded book-signatures to a signature-gathering, signature-stitching, or like machine, the leaves of each signature are successively engaged and bent outward by a series of devices so that the leaves to one or both sides of its fold are parted individually and progressively from the outer leaf inwards. The signatures S are fed from a pile A either by hand or automatically to a table 42 along which, as shown, they are carried on edge by endless gripping-bands 2, 3, and have their folded edges uppermost. A series of curved and adjustable sheet-guides 10, 11 are situated above the table 42, and, corresponding to each pair 10, 11 is provided a suction device 4 .. 7 and a sheet deflector 12, 14, or 18. The first suction-device 4 bends the outer leaf S<1> away from the remainder S, and during the forward movement of the signature, the deflector 12 enters between the leaf S<1> and the signature. Similarly, the succeeding suction-devices and deflectors part the leaves successively until the centre is reached when the opened signature passes over a guide 16 to the pivoted saddle 20 of a book-stitching machine. Freely-mounted rollers 22 project through slots in the saddle 20 and co-operate with driven rollers 21 on an extension 17 of the main framing 53 to forward the signature to a front stop 23. A stop-cock 26 is provided for each suction-device whereby the number thereof operating is arranged to correspond to the number of leaves. Suction devices may be arranged on both sides of the signature, if desired. Where all the signatures S are not identical, e.g. if one of a certain number contains a flyleaf or separate insert sheet, one of the suction devices, e.g. the device 4, is caused to operate only when this signature is fed. For this purpose, the sleeve 27 by which it is mounted on the main suction pipe 24 is rotatable on the pipe 24 so that only in one circumferential position is suction applied to the device 4. The sleeve 27 is connected by a lever and connecting rod to a ratchet-operated mechanism which allows the suction to be applied to the device 4 once for each pre-determined number of signatures fed. Specification 353,314 is referred to.

Heading C2C. #-Laurolactam is recovered from solution in an organic solvent by distillation in the presence of an additional liquid whose boiling point under distillation conditions lies between that of #-laurolactam and that of the solvent. Advantageously, the boiling point of the liquid is above the melting point of #-laurolactam (152 C.). Suitable liquids are cyclododecanone, diisopropylcyclohexane and cyclododecane. The preferred amount of the liquid is from 5 to 30 parts by weight to 100 parts of lactam. The liquid may be recycled. It may be supplied to the middle portion of the distillation column separately from the lactam solution. The process is especially applicable to lactam solutions obtained in the process described in Specification 1,088,812. In this case the additional liquid may be added at the hydrolysis stage of the production of the lactam. Preferred solvents for this process are cycloaliphatic hydrocarbons, particularly hydrocumene.
