Title: Method for the production of flexible or semi-flexible cement compositions and the products obtained thereby
IPC: C04B28/06
Filed: 1944-06-23
Abstract: Rubber is heated with a softening agent, a resin is mixed therewith, the mixture is dispersed in water, the solids are vulcanized, and the vulcanized dispersion is added to cement or mortar to produce a semi-flexible composition for facing walls, floors, ships' decks or the like.  Suitable proportions are rubber (tyre scrap) 10-50 per cent., resin, preferably coumarone, 25-50 per cent., softener 12 1/2 -40 per cent.  The softener may be pine tar, coumarone-containing fractions of coal tar and aromatic hydrocarbon containing fractions of mineral oil.  Rubber increases clasticity but reduces tensile strength, resin gives toughness but decreases elasticity, the softener gives flexibility at the expense of elasticity and tensile strength.  According to an example, 11 parts of crumbed vulcanized rubber are heated to 120 DEG  C. with 12 parts of "Pool Aromatic Extract," with stirring, and the temperature is raised to 180 DEG C. 16 parts of molten coumarone are stirred in and the mixture is allowed to cool.  This is dispersed in water with the aid of oleic acid, a wetting agent such as triethanolamine, or that known under the Registered Trade Mark "Teepol," and casein in ammoniacal solution, in an internal mixer, and to the dispersion are added sulphur, zinc oxide and accelerators, and the dispersion is vulcanized.  120 parts of the dispersion diluted to 50 per cent solids are mixed with 150 parts of portland cement, 45 parts aluminous cement, 10 parts red oxide pigment, 50 parts wood chippings, and 15-35 parts water.  The mixture sets in 16-20 hours to a slightly flexible product which adheres to concrete and metal.  In a further example quartz grit is also added.

Tubular cartons or boxes with end closing flaps are made from blanks or shown in Fig. 1 by folding the panel B, C over upon the middle. panels G, H, Figs. 2 and 3, the blank being traversed through a folding machine in a direction at right angles to the scores or creases E, E<1>, D; glue may be applied to a lip A which becomes secured to the panel C. The blanks are fed from a hopper to rollers 1, 2; 1<1>, 2<1>, Fig. 4, which pass the blanks over blades 5 to a stripping roller S working in conjunction with a glue roller R as described in Specification 8263/11; the blades 5 are adjustably carried by arms on a rod 3 and have inclined separated parts 6, Fig. 5, over which the end flaps F of the blanks pass, the panels passing between the inner edges thereof and, as the roller 1<1> is placed slightly forward of the roller 2<1>, the front edge of the blank or the lip A in its forward movement is directed downwards and against counterweighted pivoted finger 8 which momentarily arrest the blank and cause the lip A to touch the roller S and become glued. At the same time the flaps F ride up the parts 6 and raise the blank from the glue or stripping roller, the blank pushing the fingers 8 aside and coming into contact with swinging levers 9 adjustably secured on a rod 10 connected to a spring 32. The blank pushes the levers forward until the crease E is free from the rollers 1<1>, 21 or the fingers 8, when the levers 9 swing back and fold the panel B and flap A on to the panels G, H. The doubled edge E then passes over a plate 15 to rollers 16, 17, 18, 19, the rollers 18 being discontinuous and acting only on the flaps F to feed the doubled edge E over a plate 20 into recesses 21 at the lower ends of narrow pendent levers 22 carried by a rock shaft 23; the ends of the levers work in grooves in a curved grid 27 and are pushed away by the edge E of the blank up the grid 27 until the crease D has passed over the plate 20 and the panel C is free from the rollers 18, 19 when the panel is lifted by teeth or flutes on the rollers 18; the blank then collapses and is forced by the return of the levers 22 downwards to the shoot between the nose of the grid and the face 29 of the plate 20; the doubled edge D then passes between rollers 19, 30 which presses the panel C against the lip A. If the lip A is not to be glued the rollers S, R and glue tank are removed and the fingers 8 are swung upwards out of the path of the blank. The flutes or teeth of the roller 18 may be square or angular and may be resiliently mounted therein. The levers 22 and grid 27 are adjustably mounted on the frame 31 and the movements of the levers 9, 22 are limited by adjustable stops.

Abstract: 1,079,273. Interconnection systems. ASSOCIATED RESEARCH LABORATORIES (PROPRIETARY). March 22, 1965 [March 25, 1964, No. 12028/65. Headings H4K and H4R. In an intercommunication system having a plurality of loud-speaking substations connected in parallel to a common speech path, each station is provided with two switches whereby when both switches are operated in a calling station a common control line is energized so as to energize the receive transistor amplifiers in all the other stations and thus allow the caller to announce the name of the called party who responds by operating one of his switches (the speech switch) so as to energize his transmit amplifier. The caller then releases one of the switches (the call switch) and maintains his speech switch. A balance circuit, comprising transistors 3, 4 and potentiometer 11, acts as anti-sidetone circuit. The call switch 9 applies earth to control line 17 whereby a transistor 5 in each substation is tendered conducting via diode 16. The line 18 is thereby connected to loud-speaker 14 through amplifier 5, 6, 7, 8, 21. The speech switch 10 causes microphone amplifier 1, 2 to become conductive and also via diode 15 renders the loud-speaker amplifier conductive. The caller announces the name of the called party and since switch 9 is on, this is heard in the loudspeaker of each substation. The called party responds by operating his switch 10 to energize his amplifiers independently of the call signal on line 17. The caller releases switch 9. A monitor circuit may be included whereby a lamp in each of the two conversing circuits is operated and burns steadily, this lamp then flashing if any other station intrudes on the line. A busy lamp may be operated in each station. A common battery connected to terminals 19, 20 is used.
