Title: A method and a device for Providing Carton Blanks with a Coating of Plastics and a Carton Blank Coated by Means of the said process
IPC: D21H23/48
Filed: 1967-03-21
Abstract: 1,157,058. Laminates. AKERLUND & RAUSING A.B. 21 March, 1967 [25 March, 1966], No. 13227/67. Heading B5N. A method of providing carton blanks which have been provided on one surface with advertising, decorative, and/or informative texts and have been thereafter collected and punched, comprises; advancing blanks 6 in a sequence after one another in such a way that the surface of the blanks which is provided with said texts faces a molten and sticky film 4 extruded as an endless web advanced in time with the blanks and is continuously moved into contact with and pressed against the film in such a way that the margins of adjacent blanks are slightly spaced from each other, cooling the composite material web 13 thus formed whilst advancing it at the original speed of the blanks and film, and varying the speed of the composite material at a point where the film has set after the cooling of the composite material web, and has become united with the blanks, and bridges the interspace between each adjacent pair of blanks in the composite material as a separate piece, whereby the composite material is exposed to tensile stress so that the film sections between the carton blanks are stretched and break, and the separate carton blanks with the film secsections fused therewith are collected. In the device shown for carrying out the method blanks 6 are fed in sequence by rollers 2, via guiding means 5, into contact with a molten and sticky extruded plastics film 4, between a cooling roller 7 and an endless conveying web 10, supported by a pressure roller 8 and guiding rollers 9. The film 4 and blanks 6 constitute composite material 13 which, after cooling and setting of the film 4, passes via guide means 12 and rollers 9 to accelerating rollers 11, which increase its speed, thus producing tensile stress in the film and causing stretching and breaking of the film sections between adjacent blanks. If desired a number of carton blanks disposed side by side may be fed into contact with the film 4 simultaneously, the film being subsequently cut longitudinally to form the individual finished carton blanks.
Patent GB-132604-A (GB)
IPC: E01B29/05
Abstract: 132,604. Baldwin, G. D. Sept. 17, 1918. Drawings to Specification. Methods of laying track.-A permanent way is laid by first grading the track and laying sleepers at spaced intervals to receive a temporary narrowgauge line between the points where the permanent rails are to be secured. A construction train is brought forward as far as the permanent line exists, and narrow-gauge trucks carried by the construction train are propelled forward on the temporary narrow-gauge track. First, the sleeper trucks deliver the sleepers, which are placed between the spaced sleepers; then the rail trucks are brought to position; after these are withdrawn, the line is ballasted and the rails secured. The train may carry a truck with fluid under pressure, which can be conveyed by a pipe to the position where the tool or tools are to be operated. The Specification describes the same construction train, as is described and claimed in Specification 132,603, but states that the method described and claimed is not limited to any apparatus.

Abstract: 444,445. Making electric switches. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. May 3, 1935, No. 13299. Convention date, May 3, 1934. [Classes 83 (i) and 83 (ii)] Casting.-A switch contact of sintered tungsten or other difficultly-fusible metal powder impregnated with copper, silver or other easily fusible metal is made by filling a mould with the tungsten powder, sintering, preferably in vacuo, providing a gap in the mould and pouring the copper into the evacuated mould to fill the pores in the sintered block and said gap. The gap may be provided by removing a block of molybdenum or other material not affected by sintering temperature or by replacing a flat cover by one with a recess. The recessed cover may have surfaces to engage and hold the sintered block. To facilitate evacuating and reduce cost, a long mould may be used to cast a rod having the same crosssection as the contacts required and this is then cut up and ground. Any copper on other faces may be ground off at the same time. The tungsten powder may be mixed with a solution of camphor or other easily evaporated material so that fine-grain powder may be used or more of the fusible metal be absorbed or both to facilitate cutting up by a metal saw. Contacts made in this way can be easily soldered to their supports.

[Class 38 (iv)] Thermionic control, charging and discharging condensers. A transformer supplying a resistance welder is energized alternately in opposite directions by the charging and discharging or by successive discharges of a condenser ; saturation effects are thereby eliminated. Grid controlled rectifiers are employed to control the charging and discharging of the condenser. A condenser 21 may be charged through the balanced winding sections 18, 24 of a welding transformer by the synchronously timed ignition of a grid controlled gaseous valve 27 and discharged through the same windings, with added turns to replace the inductance of the transformer 15, by a valve 34 ignited during the following, or a later, half cycle of the supply current; reversed charging of the condenser by welding transformer flux is checked by a rectifier valve 40 in shunt to the condenser. Opposite half-cycles may be arranged to charge an auxiliary condenser assisting the charging impulse of the main condenser. The circuits include a manual switch 65 and a timer 62 to determine the number of shots in a weld. The conductors 16, 32 may be energized from a rectifier, and the motor 78 need not then be synchronized. Several modifications are described. The commulator controlling the grid potentials may, with a suitable valve arrangement, connect two condensers in turn during a single charging or discharging impulse and so prolong the welding current. By a bridge connector of controlled valves a single condenser may be charged successively to opposite polarities and discharged through a single winding or through balanced windings on the welding transformer. The commutator segments may be replaced by photo-electric cell apparatus operated by apertured discs.
