Title: Improvements in or relating to apparatus for slotting the edges of running webs
Inventor: ARMELIN EDWARD ROGER
IPC: B26D3/08
Filed: 1958-07-10
Abstract: 850,757. Slotting webs. CHAMBON Ltd. July 8, 1959 [July 10, 1958], No. 22166/58. Class 31 (1). Apparatus for slotting at intervals an edge of a longitudinallyrunning web comprises at least two blades projecting generally radially with respect to, rotatable about and spaced relatively to one another along, a common axis parallel with and adjacent to an edge of the web, and means for rotating the blades about their axis at the same angular speed that is related to or dependent upon the linear speed at which the web travels, the axial lengths of the blades and the axial distance between them being such in relation to the linear speed of travel of the web that one blade makes cuts in the web each forming part of each of a series of slots and another blade makes cuts in the web each forming another part of each of the series of slots. A web 28, Fig. 3, is fed by means of a roller 1 over a table 3 and support rollers 4, 5 to a traction roller 2, the rollers 1, 2 being driven from a motor-driven shaft 7 by means of helical gears 8, 9. The slotting apparatus comprises two cutting assemblies 11, 12 mounted on a shaft 10, Fig. 2, and each comprising a blade 18 secured to a hub 17 journalled on the shaft 10. The hubs have mounted thereon angularly-adjustable gearwheels 19, 20 driven from the shaft 7 by means of gear-wheels 21, 22, 26 and 27, Fig. 3. The rotary blades 18 co-operate with plates 29, 34, 35, Fig. 2, adjustably mounted in recesses in the table 3. In operation, one of the blades cuts out a portion 39, Fig. 6, from the web. Then, after the web has travelled a further distance, dependent upon the angular displacement of the blade assemblies, the second blade cuts out another portion 40 overlapping the portion 39.

Title: Production of tetramethylol acetylene diureine
IPC: C07D487/04
Filed: 1953-08-12
Abstract: A method of making substantially pure crystals of tetramethylol acetylene diureine in which a mixture of formaldehyde or paraformaldehyde and acetylene diureine is heated in an alkaline medium to form tetramethylol acetylene diureine and the crude reaction mixture is evaporated under reduced pressure to form a concentrate containing from 80 per cent to 90 per cent by weight of solids, is characterized in that the concentrate is dissolved in a water-soluble organic solvent or solvents, such solvent or solvents being capable of dissolving the concentrate but being a non-solvent for pure tetramethylol acetylene diureine and thereafter allowing crystals of tetramethylol acetylene diureine to separate from the solution.  Solvents mentioned are methanol, ethanol, isopropanol, propionic acid, diethylene glycol, the monoethyl ether of ethylene glycol and mixtures e.g. of methanol and isopropanol.  Acetone and n-propanol are unsuitable.  In examples acetylene diureine, prepared by reacting glyoxal with urea, is reacted with paraformaldehyde suspended in an aqueous alkaline medium, the mixture is concentrated and the desired product obtained on cooling and adding methanol (I); in similar processes tetramethylol is obtained from concentrated syrups by the addition of ethanol (II); isopropanol (III) and the monoethyl ether of ethylene glycol (IV).

Patent GB-223895-A (GB)
Abstract: 223,895. Grimme, Natalis, & Co., Akt.-Ges., (Assignees of Hoffmeister, H.). Oct. 26, 1923, [Convention date]. Multiplying and dividing apparatus; selecting denomination. - A totalizer carriage shifting device comprising a T-shaped shifting lever 10 connected by transmission members 18 with the carriage lock 5 and carrying pawls 13 which limit the movement to one step has also the shifting lever displaced bodily relatively to its pivot 9 and at right angles to the direction of movement of the carriage for free movement of the carriage. This lock 5 co-operates with a stationary rack 7 and is guided by pins 2, 3 and 9 on the base plate 1 of the laterally-movable totalizing-counter. The shifting lever 10 is pivoted on the pin 9 by means of a slot 16 and when this lever is moved by its handle 11 in the direction of the arrow the right-hand lug of two upstanding lugs 14 thereon rotates the righthand member 18 pivoted at 17 on the base-plate 1 which withdraws the lock 5 against its spring 4. The carriage thus moves to the right, but meanwhile the left-hand pawl 13 engages the stationary rack 20, the lever 10 thus moving to the right until arrested by the left-hand lug of two upstanding lugs 15 thereon abutting against the pawl 13. For free movement, the lever 10 is pressed in at right angles to the direction of movement of the carriage and then moved right or left. The slot 16 permits this, the members 18 withdraw the lock 5 and the pawls 13 are now too far from the rack 20 to engage therewith. In a modification, the lock 5 is reversed and one rack serves for co-operation with the lock 5 and the pawls 13. The dimensions of the transmission members 18 are such that a very slight displacement of the lever 10 suffices to effect the release of the carriage.
