Patent GB-729183-A (GB)
Title: Cellulosic plastic compositions
IPC: C08L1/08
Filed: 1953-03-23
Abstract: A composition capable of being dyed with acid dyes and with metalliferous dyes comprises an intimate mixture of a cellulose ether or cellulose ester and a polymeric aminoethyl vinyl ether of the formula <FORM:0729183/IV (a)/1> or an acid salt thereof, in which R1 and R2 represent hydrogen atoms or the same or different saturated or unsaturated aliphatic hydrocarbon radicals or, together with the atom of nitrogen, constitute a heterocyclic ring, and n is an integer greater than 1.  The cellulose derivative and the vinyl ether may be dispersed in a common liquid dispersion medium to form a true solution or a fine suspension, and the dispersion medium may then be removed, e.g. by evaporation, leaving a composition which, like wool, may be dyed with acid dyes or with metalliferous dyes such as chrome dyes.  The cellulose derivative may be cellulose acetate, propionate, butyrate or acetobutyrate or ethyl cellulose. The polymeric ether may be a polymer of the vinyl ether of dimethylaminoethanol, diethylaminoethanol or N-hydroxyethyl-pyrrolidine.  The polymer may be obtained by polymerizing the monomeric ether in the presence of boron trifluoride.  Two or more of the monomeric ethers may be copolymerized and the copolymer may be incorporated in the cellulose derivative.  The polymer may be used as such or in the form of an acid salt formed with perchloric, fluorboric, sulphuric, formic, acetic or trichloracetic acid.  The proportion of polymeric ether in the composition may be 1-20 per cent based on the weight of the cellulose derivative.  Filaments, films and other articles may be obtained from solutions or dispersions of the composition.  Dry or wet spinning processes may be employed. Filaments or fibres may be mixed or associated with wool to give mixed fabrics which dye uniformly with acid or metalliferous dyes. In an example, a solution of cellulose acetate in acetone containing 5 per cent, based on the weight of the cellulose acetate, of polymeric vinyl diethylaminoethyl ether is dry-spun to form filaments.  A yarn made of the filaments is dyed by treatment with a hot formic acid solution of Cyanol extra. In another example, a film is obtained from a solution of cellulose acetate containing polymeric vinyl dimethylaminoethyl ether.  The film is immersed in a dye bath containing acetic acid and Cyanol extra. The temperature is raised to 97 DEG  C. in 15 minutes and maintained at this value for a further 15 minutes.  Sulphuric acid is added and the temperature of 97 DEG  C. is maintained for a further 30 minutes.  The dyed film is then washed.  Specification 713,487 is referred to.

Title: Improvements relating to guards for guillotine machines
IPC: B26D7/22
Filed: 1933-03-17
Abstract: 410,948. Machinery guards. CLUNAS, R. A., and GREIG, D. W. L. M., 28, Dundee Street, Edinburgh. March 17, 1933, No. 8090. [Class 80 (iv).] Relates to guillotine machines in which a weighted lever is used to apply pressure to the work clamp. When the machine is started the lever falls and the first part of the movement is used to urge the guard 25 outwardly from the knife. The guard is connected by a linkage with a lever 9 pivoted at 10 to the frame and having a roller 8 adapted to reciprocate in a slotted guide 5 fast to the weighted lever 3. When the lever is in raised position the roller is in the horizontal part 6 of the slot so that when the lever begins to fall the lever 9 is turned on its pivot and the rod 11 falls. The motion is communicated to the side rods 24, 25 of the guard which swings out about a shaft 21. After a certain travel pins 34 on links 17 are engaged by catches 35 and the guard is locked in guarding position. The lever 3 continues to fall, the roller 8 moving up the vertical slot 7. The catches 35 are part of links 20 which actuate the shaft 21. If the operator's arm be trapped by the guard, springs 33 will yield. These connect a pin 34 on the link 17 with a pin 19 on the link 20 which works in a slot 18 in the link 17, thus allowing the guard to yield if an obstruction be met on the return stroke. The rods 24, 25 are telescopic.

Title: Recovering values from waste pickle liquor
IPC: C01G49/06
Filed: 1967-02-21
Abstract: H2SO4 and Fe2O3 are recovered from wast pickle liquor containing FeSO4 and dilute H2SO4 by evaporating below 250 DEG  F., preheating the concentrated liquor with added carbonaceous fuel such as fuel oil, mineral oil, fuel gas or powdered coal in a closed space, atomizing the preheated concentrate in air and decomposing the atomized stream by heating it in an oxidizing atmosphere to such a high temperature (about 3000 DEG  F.) that all the remaining water is converted to steam, the H2SO4 decomposed to SO3 and steam, and the FeSO4 into SO3, steam and solid Fe2O3 particles which are separated from the effluent gases.  The SO3 is separated, too, and reacted with water from the earlier evaporation step to form H2SO4. The hot gases from the pyrodecomposition step can be used by heat exchange with triethylene glycol to provide heat for the earlier evaporation step, and steam from this step used to preheat air used in the thermal decomposition, to about 400 DEG  F.

Title: Foam breaking device
Inventor: PHILLIPS KENNETH LLOYD
IPC: B01D19/02
Filed: 1960-03-08
Abstract: <PICT:0880593/III/1> Leading from the top of the vessel 1 is a conduit 2 which is connected to a nozzle or jet 3 mounted in the side wall 4 of a cylindrical vessel 5 forming a separation chamber 6.  The nozzle 3 has a plain cylindrical restricted passage, the diameter of which is of a size to impart sufficient velocity to the foam passing through it to ensure that the material issuing from it is essentially free of bubbles.  There is mounted in chamber 6 a baffle 8 in opposed relation to the nozzle 3 to receive and deflect the output of the orifice.  The angle of inclination of the baffle may vary from about 30 to 45 degrees and is shown approximately 37 degrees to the horizontal.  Vessel 5 may have a conical bottom portion 10 for collection of liquid and an outlet conduit 11 leads therefrom.  The conduit 11 communicates with a pump 12 which may be driven by a motor 13 to pump the collected liquid back into the tank 1 through conduit 14.  The pump and foam breaking assembly must be constructed to withstand normal steam sterilization pressures and temperatures encountered in vessel 1. In operation, effluent air from the tank 1 passes into the separation chamber through conduit 2 and nozzle 3. Under foaming conditions, resistance in the nozzle results in a pressure build up, which may be of the order of 3-5 pounds per square inch, in the tank 1.  Thus, the foam is forced through the nozzle orifice at 100-300 feet per second against baffle surface 9.  A vent 15 is provided in vessel 5 for effluent air.  The energy required for breaking up the foam may be supplied by the air used in the procedure or produced in fermentation, no pump being required.
