Abstract: 1,167,222. Laminating machine. R. M. BERGSTEIN, and F. D. BERGSTEIN. 1 Feb., 1967 [1 Feb., 1966], No. 4921/67. Heading B5N. [Also in Division F2] A machine for assembling a carton blank and a liner therefor in which one of the parts is deposited on the other and the assembly so formed delivered to a conveying means comprising upper and lower travelling belts 33, 28, Fig. 3, respectively, between which the assemblies are engaged and advanced, comprises means in association with the belt 33 which cause it to define an open nip with the belt 28, and means which operate upon the entrance of an assembly into the open nip to temporarily close it, so that the assembly is engaged and advanced by the belts upon closing of the nip. In the machine described the open nip is provided between a portion of the belt 33 which passes around a roller 34, and the underlying portion of the belt 28. The roller 34 is rotatably mounted on a rocker arm 35 which is pivoted at 36 and which is connected via linkage to a cam follower in engagement with a cam rotated in synchronism with a conveying arrangement for the carton blank and liner assembly, so that as each assembly enters the open nip between belts 33 and 28 the cam acts on its follower to move the linkage and pivot the arm 35 so moving roller 34 towards belt 28 and closing the nip. In operation of the machine, see Fig. 2, carton blanks 1, fed one at a time by a wheel 18 on to conveyer chains 21 which have pins 22 which push each blank along, pass beneath a roller 24 which applies adhesive in spots or lines to the blanks, and then beneath a platform 15 supporting a liner which has been previously fed thereto by rolls 13. The pins 22 remove the liner from the platform and locate it on the blank, the assembly so formed then passing from the chains 21 to the open nip between the belts 33 and 28. As the assembly passes beneath roller 34 the cam, which is carried by the drive-shaft for chains 21, is effective to cause the roller 34 to move and close the nip. The leading end of the assembly then enters a further nip between another portion of belt 33 and belt 28 at roller 71, before the trailing end of the assembly is freed by the cam causing the closed nip to open.

Title: Production of anhydrous ketene
Filed: 1955-02-23
Abstract: Substantially anhydrous ketene is produced by subjecting a gaseous mixture containing ketene and water vapour, the water vapour forming not more than 5 per cent by weight of the mixture, to treatment with a hydration catalyst so as to effect reaction between the water and a portion of the ketene.  Suitable catalysts are phosphate esters, such as triethyl phosphate, and phosphoric acid, suitable proportions being 0.01 to 10 per cent, preferably 0.2 to 0.5 per cent, based on the weight of ketene.  The reaction may be effected at 0-200 DEG  C., preferably at 50 DEG  C. or lower.  The reaction between ketene and water produces acetic acid and acetic anhydride which may be removed easily by vapour separators.  A mixture comprising ketene and more than 5 per cent by weight of water vapour may be cooled at least to its dew point, and the condensate separated to leave a gaseous mixture of ketene and not more than 5 per cent by weight of water vapour which may then be used in the process.  The mixture of ketene and water vapour may be obtained by pyrolysis of acetic acid or acetic anhydride, in the vapour phase at atmospheric, sub-atmospheric or super-atmospheric pressure, at 600-800 DEG  C. in the presence of 0.1 to 1.0 per cent, preferably 0.2 to 0.5 per cent, by weight of diammonium phosphate, triethyl phosphate, tricresyl phosphate or other ester of phosphoric acid, based on the weight of the feed stock.  For example, acetic acid and the catalyst are passed, at a pressure between atmospheric and 20 pounds p.s.i.g., through a reactor at 625-800 DEG  C. for a reaction time of 0.01 to 5.0 seconds, preferably 0.5 to 3.0 second, and the resulting mixture is neutralized with ammonia, pyridine, aniline or an aliphatic amine. When ammonium phosphate is used as a catalyst, the neutralizing agent will be present in the reaction mixture.  The neutralized gases are cooled to 50 DEG  C. to condense most of the acetic acid, acetic anhydride and water and the resulting mixture of ketene and water vapour is treated with a hydration catalyst as described.  A detailed example is given.

Title: Rust and scale removing tool
IPC: B08B9/04
Filed: 1933-02-22
Abstract: 414,792. Cleaning iron &c. surfaces. METZ, F., 26, Blanckestrasse, Merseburg, Germany. Feb. 22, 1933, No. 5464. [Class 99 (ii).] Rust and scale is removed from iron &c. surfaces by tools, viz., a scraper 20 and a wire brush 21, mounted on one end of a rod 19, the other end of which is connected to a piston 16 adapted to reciprocate within a cylinder 15 under the action of compressed air, one or both of the said tools being effective according to the angle of inclination of the rod 19 with respect to the surface being operated upon. The air supply is controlled by a rotary valve 22, the rotatable part 41 of which constitutes a handle for the device, and air is admitted alternately to opposite sides of the piston by slide valves 17, 18 located at the ends of the cylinder 15. With the parts disposed as shown in Fig. 6, the valve 22 being open, air will pass through ports in a disc 39 and channels 23, 24 to the middle of the valve 17 and from there to the valve 18 through a channel 25. The valve 18, and with it the piston 16, will commence to move to the right, and when the valve is clear of the part 46 the air will impinge on the piston and compel it to complete the stroke, the air from the previous stroke being exhausted through ports 31<a> and channels 29, 26, 30 to the exhaust channels 31 until the piston covers the inlets to the said channels 29. The remaining air is then compressed and forces the valve 17 to the right, whereupon the channel 24 is closed by this valve and the air through the channel 23 is directed to the right-hand side of the piston. The piston will now move to the left, the air from the previous stroke exhausting through the valve 18, channel 25 to the middle of the valve 17, and channels 26, 31. The exhaust air is conveyed to the brush 21 where it disperses the dust &c. Towards the end of this stroke the piston will move the valve 18 to the left ; as a consequence the exhaust ports 31<a> will open, thus reducing the pressure in the cylinder and allowing the air on the right of the valve 17 to move the latter to the left. A channel 28 is provided in the cylinder for supplying starting air to move the valve 17 to the right should it be in the position shown when the piston is at rest at the right-hand end of the cylinder.
