Title: Box erecting machine
Inventor: HOYRUP SIGURD JOHANNES
IPC: B31B3/46
Filed: 1960-08-05
Abstract: 901,594. Box making machines. BALJAK CORPORATION. Aug. 5, 1960, No. 27185/60. Class 18. In a machine for erecting carton blanks 11, to which an adhesive is applied, and comprising a reciprocating plunger 12 which moves into a folding die 13, a compressive force is applied on the erected blank between the die and the plunger, the plunger drive including a piston and cylinder assembly in which a flow restriction is provided for the fluid displaced from the cylinder whereby the drive operates continuously but the plunger is arrested while the compressive force is applied, and then accelerates to catch up with the drive mechanism. Members 22, 23 prefold and apply glue to flaps F so that as the blank enters the die the flaps F overlie faces 20, 21 of the plunger and end panels E are folded up on the outside of and are stuck to the flaps F. The plunger which is mounted on a bar 56 is driven by an electric motor 41 through a chain 45, gears 46, 47 and a linkage 51, 50, 54, 53, a switch 59 being opened just before a blank is forced into the die and a second switch 60 being closed to complete the circuit if the plunger is not stopped from entering the die for example by a mis-placed blank, members 24, 25 actuated by a piston 35 and cylinders 36, and levers 26, 27 pivoted at 30, 31 respectively apply pressure to the flaps F and panels E and arrest the plunger at its lowermost position. The drive includes two cylinders 66, 67 mounted on a plate 65 carried by the bar 56 and pistons 68, 69, rods 70, 71 connecting the pistons to a plate 72. Rods 74 connect a plate 73 locating the tops of the cylinders to the plate 65. Further rods 77, 78 carried by the plate 65 carry the plunger 12. The pistons divide the cylinders into upper and lower chambers, the upper chamber being open to the atmospheric air through filters 81. The lower chambers are in communication with the atmospheric air through valve assemblies 82 and 83 and similar filters 81. The valve 83 allows air to enter freely into the lower chamber of the cylinder 67 but allows only an adjustable limited escape. The valve 82 allows free escape but only an adjustable limited entry to the lower chamber of cylinder 66, This arrangement allows the plunger to decelerate and to be arrested by the members 24, 25 and then to accelerate and catch up with the drive mechanism. A hydraulic snubber 92 arrests the plunger at its lowest position. Resilient projections on the inside of the die bow the sides of the box inwardly to ensure that it is ejected by the next blank. Specification 901,591 is referred to.

Filed: 1973-06-12
Abstract: 1428684 Urea UNIE VAN KUNSTMESTFABRIEKEN BV 12 June 1973 [12 June 1972] 27876/73 Heading C2C Urea is prepared by reacting ammonia and carbon dioxide at elevated temperature and pressure to form a urea synthesis solution which is heated in a heat exchange zone to 205‹ to 250‹ C. and subsequently stripped in countercurrent to a gas, the gas mixture thus formed comprising ammonia, carbon dioxide and water vapour being recycled to the urea synthesis step. The synthesis solution is preferably passed co-currently with the gas mixture liberated by the heating through the heat exchanger, the latter generally being a single-pass heater wherein the heating is effected by the use of combustion gases of a gaseous or liquid fuel. A residence time in the heat exchange zone of not more than 10 seconds is preferred. Part of the water vapour in the gas mixture from the stripping zone is generally separated therefrom by passing the gas mixture through a rectifying zone counter-currently to the urea synthesis solution to be heated.

Abstract: 463,673. Typewriters. INTERNATIONAL TIME RECORDING CO., Ltd., and MILES, J. W. Oct. 9, 1935, Nos. 27886, 33143, and 35447. [Class 100 (iv)] Paper-supports.-In an arrangement for raising the platen to provide a free space for the manipulation of webs and carbon sheets, the platen is guided vertically by extensions of the carriage and is connected to a toggle, and releasable means is provided for holding the platen in raised position. The platen 3, Figs. 1 and 3, is mounted in plates 36 provided with pulleys 36<1> engaging guide-slots 35 in extensions 34 of the carriage 5, each plate being connected by a toggle 39 to a shaft 41. The toggles are normally slightly beyond the straight position, and are prevented from breaking forwardly by a pin 44 on one of the plates 36. Depression of a finger-piece 40 on the shaft breaks the toggles and thereby raises the platen, a catch 42 co-operating with a notch 43 in one of the plates 36 to hold the platen in raised position. When pressure is applied to the platen-knobs 4, the catch 42 is released, the platen is depressed, and the webs are bent around the platen. Web guiding and cutting arrangements.- The webs are held in engagement with the platen by means of a spring-urged bail 47 pivoted on the shaft 41 and normally abutting on a bar 51 provided with a tearing-edge. When the platen is raised, the bail is swung aside by means of a rocking arm 45 operated by the pin 44. The webs are clamped to the tearing-bar 51 by means of a bar 52 which is secured to arms 53 on the shaft 51, and is swung into the position shown in Fig. 3, when the platen is raised. Carbon-sheet arrangements.-A carriage 12, supporting a carbon-sheet trolley 23<1> runs on rails 17, 18 on a base 2 and is resiliently coupled to the platen-carriage 5 by means of springs arranged on a rod 6 which passes through lugs 11 on the carriage and is secured to arms 7 on the platen-carriage.

Filed: 1926-09-13
Abstract: 283,830. Ellis, G. B., (American Sheet & Tin Plate Co.). Sept. 13, 1926. Purifying fats and oils; recovering fats and oils from waste waters.-In a method of separating oil, such as palm oil, from an emulsion thereof with an alkaline solution enough alkaline solution is added to purify the oil partly, the emulsion is broken by addition of an acid, and the oil separated from the broken down emulsion, as by gravity. The emulsion may be passed from a trough 31 into the breaking and mixing chamber 33 of a tank D, where a measured quantity of sulphuric acid is added from a tank 42 by a pump 43, and into which steam is passed by a pipe 39 to heat the. mixture to, say 140‹ F. The emulsion, thus broken, overflows into a chamber 34<a> and separates by gravity, the oil rising to flow over the inclined top of a wall 35 into a chamber 35<a>, this action being assisted by a steam coil 38, and the water passing away by a pipe 45, the top of which is about 1¢ ins. below that of the wall 35. The oil collecting in the chamber 35<a>, which is heated by a steam coil 41, retains about 60 per cent of water. The invention is described as one step in the process for the removal, purification, and recovery of oil from tin plate described and claimed in Specification 283,614.
