Title: Method of recovering benzene hydrocarbons
IPC: C10K1/08
Filed: 1958-01-24
Abstract: 825,388. Gas scrubbing processes. KOPPERS G.m.b.H., H. Jan. 24, 1958 [May 24, 1957], No. 2484/58. Class 55 (2). A method of recovering benzene hydrocarbons from a gas, such as coke oven gas, comprises directly cooling the gas under pressure below zero degrees C. by calcium chloride lye in the presence of a benzene solvent of low freezing point, the direct cooling being performed in a plurality of stages in which the gas is passed alternately in uni-flow to and in counter-flow with the calcium chloride lye. Gas, having a pressure of 8 atmospheres and a benzene content of 25 grams per Nm<SP>3</SP> is passed through heat exchangers 11, 12 in indirect heat exchange with the cooled treated gas flowing in uni-flow and counter-flow respectively, to cool the gas to 5‹ C. Condensates flow to a separator 15 from which water is withdrawn at 16 and raw benzene at 17. The cooled gas flows into a uni-flow packed washer 19 supplied with calcium chloride lye at a temperature of -20‹ C. through conduit 22 to which solvent naphtha is added through conduit 23. The mixture of calcium chloride lye, solvent naphtha and dissolved benzene passes through conduit 24 to the sump of a counter-flow washer 25 and thence to a separator 27. Calcium chloride lye withdrawn through conduit 28 is freed from excess water at 29, cooled to - 20‹ C. in cooler 31 and passed through conduits 32, 33, to the washers 19, 25, respectively. Solvent naphtha from separator 27 has its benzene content removed in evaporator 35, is cooled at 38 and further cooled at 40 to about -20‹ C. The cold solvent naphtha is passed through conduits 41, 42, to the washer 25. The gas from washer 19, at a temperature of - 15‹ C. is passed to washer 25 to flow in countercurrent to solvent naphtha introduced at 42, then in countercurrent to calcium chloride lye and solvent naphtha, which mixture passes through counter 44 to the sump, and finally in countercurrent to solvent naphtha alone, the gas then being at - 17 ‹ C. and having a benzene content of less than 0.3 grams per Nm<SP>3</SP>. Instead of solvent naphtha, ansole may be used.

Title: Improvements in or relating to the manufacture of polyurethane foamed structures
IPC: C08J9/02
Filed: 1965-01-20
Abstract: Polyurethane foamed structures are produced by reacting a polyol with a polyisocyanate and sodium borohydride so that hydrogen gas is produced in situ simultaneously with the urethane polymer.  The sodium borohydride may be mixed with the polyisocyanate prior to the addition of the polyol, and heat may be used.  The borohydride may comprise solid particles which are preferably 0.001-0.03 inch. in diameter, and the amount used may be up to 10% of the combined weight of the three components. The polyol may be a polyhydric alcohol or a polymer such as a polyether, polyester or polyesteramide.  Catalysts may be used both for the polyol-polyisocyanate and or the polyol-borohydride reactions, and for the latter cobalt chloride is preferred.  Lists are given of suitable acyclic and aromatic di- and tri-isocyanates, glycols, triols, amino-alcohols, straight and branched chain polyesters, polyesteramides, linear and branched polyethers, as well as hydroxy acids such as castor oil and glycerol monoricinoleate.  It is stated that the reactants may be chosen so that the formation of the polymer and the evolution of gas proceed at the same rate as well as to control the properties of the product. Listed catalysts include tertiary amines and phosphines, tin compounds, sodium methyl siliconate, iron acetyl acetonate, cobalt naphthenate, zinc stearate and sodium salicylate.

Title: Improvements in automatically threading shuttles for looms for weaving
IPC: D03J5/24
Filed: 1924-02-05
Abstract: 218,941. British Northrop Loom Co., Ltd., (Northrop Loom Co.). Feb. 5, 1924. Shuttles.-The threading device of an automatically-threading shuttle for looms provided with automatic weft-replenishing mechanism is constructed to permit ready unthreading on the occurrence of an overthrow or looping of the thread. A thread director 17 and a scroll-like thread casting and guiding device 22 is situated within an unobstructed longitudinal thread passage 12 formed by the walls of a threading-block 10, this passage permitting free entrance and exit of the thread, which passes over a bridge 31 on its way to the side delivery eye. If a loop or overthrow occurs when the shuttle is suddenly arrested in the replenishing box, as shown in Fig. 3, the loop of thread passes over the edge of the device 22 and is finally cast away from this device as shown in Fig. 4. When the shuttle is picked from the replenishing side, the thread reenters the passage 12 and the shuttle is threaded as shown in Fig. 5. If the thread becomes looped about the thread casting device 22 or the thread director or both, the pull of the thread on a subsequent pick causes the loop or loops of thread to be cast from these devices and subsequently the thread passes under the central of these devices and the shuttle is threaded. If the thread is not retained by the side delivery eye but escapes over the top of the thread director, the part 28 of the thread casting device still retains the thread until the shuttle is again threaded on subsequent picks. The device 22 has a widened base portion which may fit in a slot 27 and may be secured in position by means of the transverse bolt used to secure the threading block to the shuttle. In a modification, the terminal end portion of the thread casting device is not carried beyond the main body of the device but turns inwards. The longitudinal thread passage may be formed otherwise than by the walls of a threading block.
