Title: Male embossing dies for flat and rotary embossing dies
IPC: B29C59/02
Filed: 1969-02-19
Abstract: 1,260,181. Embossing surfaces. HALLMARK CARDS Inc. 19 Feb., 1969 [21 Feb., 1968], No. 8917/69. Heading B6C. A method of making an embossing die provided with background relief around the design comprises the steps of preparing a mask having opaque design areas, positioning the mask over a photosensitive sheet of a thickness substantially equal to the amount of background relief required, exposing the photosensitive sheet through the mask, developing to remove image areas from the photosensitive sheet, removing the mask, and forming a matrix against the developed sheet while the latter is supported on, and aligned with, a plate bearing the design, the matrix product serving as the embossing die. In an example, the design is engraved in a magnesium alloy master plate (10), Fig. 1 (not shown), a negative (22) is moulded thereagainst in a phenolic resin, Fig. 2 (not shown), and the negative is used to form a phenolic duplicate die 30, Fig. 3 (not shown), which may serve as the female embossing die of a press. A pressure-sensitive film (38), Fig. 4 (not shown), comprising a synthetic resin backing with a coating of pressure-rupturable cells, is placed over the die, and impingement of balls 50, Fig. 5, in a vacuum frame 48 on film (38) causes the supported areas to become clear, the unsupported areas over the design remaining opaque, and being subsequently dyed, Fig. 6 (not shown). The pressure-sensitive film (38) is stripped from the duplicate die 30, and a photosensitive sheet 56 is pressed against the die, Fig. 7 (not shown); the photosensitive sheet 56 is of such a thickness that it will provide the desired background relief, and is fixed to the die 30 by solvent. The dyed pressuresensitive film (38) is again placed in alignment over the die 30 and sheet 56, Fig. 8 (not shown), and this assembly is exposed to ultra-violet radiation directed normally to the surface thereof, Fig. 9 (not shown). Film (38) is again removed, and the unexposed areas of sheet 56 are washed out, Fig. 10 (not shown). The male embossing die 74 is formed in a press 78, 80, Fig. 11, against a sandwich made up of duplicate die 30, developed sheet 56 and a pressure deformable, substantially incompressible sheet 76 of lead foil providing paper clearance. The die 74 is formed of synthetic resin, preferably a diallyl isophthalate reinforced with glass fibre and may be translucent. Aligning cones are provided throughout the process in diagonally opposite corners of plate (10), negative (22), and die 30, and registration holes may also be supplied in film (38) and sheet 56; the aligning cones 86, 88 together with the corners of the assembly are cut away after moulding and registration holes 90 are drilled through both die 30 and die 74 so that alignment pins (92) may be inserted during make ready, Fig. 12 (not shown), of an embossing press. The invention is also applicable to rotary embossing dies.

As shown in Figs. 1 and 2, the probe assembly 20 comprises a cylindrical finish gauge 42 to engage the neck of a bottle and a reciprocable plug gauge 40 to measure the internal neck diameter of the bottle. If the bottle does not satisfy tolerance limits in these respects, trips 130, 170 associated with the gauges fail to pass through cut-outs 134, 174 in flags 132, 172 thereby operating microswitches and actuating a reject mechanism 350. Also provided is a body gauge 36 comprising two ring gauges 180, 182 to gauge the outside dimensions of a bottle, each ring gauge comprising two jaws 190, 192 with inwardly biased recessed members 202, 204 which control magneticallyoperable switches 250, 252, 262, 264 and thence the reject mechanism 350. An electric motor (60), Fig. 3 (not shown), drives the first set of eliptical gears 66, 68 which drives via a crank 56 a parallelogram linkage 22 comprising cranks 50, 52 and a suspended link 54 carrying the probe assembly 20. The first set of gears, in driving the link 54, also drives, via cranks 50, 52 and shafts 322, 324, two parallelogram linkages 32, 34 on which the body gauge 36 is mounted. The probe assembly 20 and the gauge 36 thus track the movement of a bottle along the conveyor 16. The carrier link 54 is speed modulated by the elliptical gears 66, 68 such that it tracks a bottle at low speed but returns at high speed. A second set of elliptical gears 66, 140, 180 degrees out of phase with the first gear set 66, 68, drives the plug gauge 40 relative to the link 54. The feed of bottles B is synchronized with the movement of the probe assembly 20 by a feed worm 82 which is also driven by the motor (60).

Title: Process for the manufacture of saturated aliphatic percarboxylic acids
IPC: C07C409/24
Filed: 1963-03-08
Abstract: Organic solutions of saturated aliphatic percarboxylic acids are made by oxidizing a solution of a corresponding aldehyde in an inert solvent with at least the molar proportion of gaseous oxygen or a molecular oxygen containing gas in the presence of an iron or a cobalt or a manganese salt which is soluble in the solvent, as a heavy metal catalyst, at temperatures within the range between 0 DEG and 50 DEG  C. and, if desired, under pressure, wherein a small proportion of at most about 1% by weight (calculated on the aldehyde used) of the peracid formed on oxidizing the aldehyde is added to the aldehyde which is dissolved in the inert organic solvent, the peracid being added to the aldehyde before the latter is oxidized with the oxygen or molecular oxygen containing gas. As solvent there is for preference employed an ester, a ketone or a hydrocarbon either alone or in combination, and it is preferred to employ a solvent which has a boiling-point higher or lower than the peracid by a difference of at least 30 DEG  C.  The peracid solution obtained may be stabilized by incorporation therein a small proportion of a alkali metal or ammonium salt of orthophosphoric acid, polyphosphoric acid or N,N1diethyl-dithio-carbamic acid.  In a preferred form of the process the solvent comprises a mixture of two components boiling at temperatures respectively higher or lower than the peracid, the peracid being removed together with a component boiling at a temperature lower than the peracid from the solvent mixture with a resultant formation of a catalystfree peracid solution, and the catalyst containing solvent boiling at a temperature higher than the peracid is used again for making peracid, if desired; the solvents boiling at a temperature higher than the peracid specified including ethylene glycol diacetate, diethyleneglycoldiacetate, propyleneglycoldiacetate or glycerol triacetate, and solvents boiling at a temperature lower than the peracid which are specified as particularly useful include acetone, ethyl acetate, methyl acetate or methyl ethyl ethyl ketone.  The invention is described with reference to a flow sheet (not shown) and examples are given of the oxidation of acetaldehyde using ferric chloride.  Further are described the oxidation of acetaldehyde and methyl acetate using ferric acetate, acetaldehyde in acetone using ferric chloride, propionaldehyde in acetone using cobalt chloride, acetaldehyde in a mixture of methyl ethyl ketone and diglycol diacetate using ferric chloride.

Title: Method of purifying nicotinamide
IPC: C07D213/78
Filed: 1950-04-17
Abstract: Nicotinic acid is separated from a mixture of nicotinamide and nicotinic acid by dissolving said mixture at an elevated temperature of at least 60 DEG  C. in an aliphatic ketone having a boiling-point higher than that of water, adding to the resulting solution both water and a sufficient amount of calcium hydroxide to convert the said nicotine acid to calcium nicotinate, driving off the added water by heating and filtering off the resulting precipitate of calcium nicotinate.  The filtrate may be freed from basic material by adding water and finely-divided silica, agitating for several hours at an elevated temperature of at least 60 DEG  C. to absorb basic material, driving off the added water by means of heat and filtering off the added silica, the filtrate may then be chilled to cause crystallization of the nicotinamide which is then recovered.  The aliphatic ketone may have a boiling-point above 100 DEG  C. but not higher than 165 DEG  C., and both filtration steps referred to above are carried out while the solutions are hot.  The preferred boiling-point range for the aliphatic ketone is from 150 DEG  to 165 DEG  C.  Suitable ketones mentioned are methyl isobutyl, ethyl propyl, methyl amyl, and ethyl butyl ketones.  One example is given.
