Title: Improvements in soap products and in the manufacture thereof
IPC: C11D13/20
Filed: 1937-06-17
Abstract: <PICT:0486819/III/1> <PICT:0486819/III/2> Soap powder is obtained from kettle soap (water content about 30 per cent) or from filled soap (water content about 40 per cent) by reducing the water content to a predetermined degree, e.g. to 5-25 per cent, converting the partially dried soap into a plastic or semi-fluid mass and then into discrete particles, and solidifying the particles.  During the plasticizing stage there may be introduced: perfumes, colourings, and sodium perborate or other filler affected by water and heat; air or other gas whereby uniformly aerated particles are produced; and water to correct over-drying.  Suitably, a mixture of 85,3 lb. of anhydrous soap, 11,7 lb. of sodium silicate, 3,0 lb. of sodium carbonate, and 36,5 lb. of water flows from a crutcher 5 to chilling rolls 7; the ribbons pass through a hot air drier 8 and a pipe 9 to a hopper 10 of the jacketed plasticizer 11 in which the soap is worked at 165-212 DEG  F. and about 25-30 lb. pressure along with air admitted with the soap, and if desired with air, other gas, perfumes, and alkali or other fillers introduced by a pipe 30; the worked mass is forced through a jacketed discharge-head 19, a pipe 28 and a valve 27, and sprayed by a nozzle 34 into a chamber 29 by compressed air or steam from a pipe 35; air from a blower 39 is simultaneously blown into the chamber 29 by a pipe 38, this air being cold if no further dehydration but only surface cooling of the particles is required, moistened if hydration of the particles is desired, and relatively hot, e.g. 360 DEG  F. if further drying is to be effected; the vapours pass through a separator 46 to a pipe 47; the soap powder falls through an outlet 48.  The drying of the soap particles in the chamber 29 may be increased by forcing in air by a pipe 41 and a nozzle 42 to give the soap particles a helical path and consequently a longer time in the chamber.  The nozzle 34 may be replaced by: (1) a flattened nozzle 38, Fig. 2, within a wedge-shaped casing 36 having air- or steam-inlet pipes 42 and staggered notches 39, 40 at the discharge end; or (2) a flattened nozzle delivering on to a roller turning slowly relatively to a wire brush rotating rapidly thereover with a slight clearance.  The plasticizer 11, as described in U.S.A. Specification 2,048,286, comprises two parallel intermeshing screws driven in the same direction at the same rate, and a jacketed casing which encloses the screws snugly except at the intermeshing zone, so that the soap cannot pass directly from the hopper 10 to the head 19 but must pass from the convolutions of one screw to the convolutions of the other through the narrow passageway at the intermeshing zone.

Abstract: 830,593. Scissors. FRITZINGER, G. H. May 27, 1958, No. 16910/58. Class 30 [Also in Group VIII] A scissors cutter comprises a pair of pivotally interconnected frame members, transverse blades mounted on portions of the frame members remote from the pivot of the latter and having cutting edges engageable with each other as the frame members are turned towards one another, at least one of said cutting edges being inclined to the direction of relative movement between the blades, one of the blades being rigidly secured to its frame member and the other blade being pivoted to its frame member on an axis substantially parallel to the pivot axis of the frame members, means for biasing said other blade about its pivot axis to provide contact pressure between the blades when they are engaged with each other, the cutting edges of the blades being inclined relative to each other as viewed in the direction of relative movement between the blades to provide a progressive point contact between the cutting edges with retraction of the pivoted blade about its pivot axis against the force of said biasing means as the blades are progressively engaged. As shown, the scissors cutter is adapted to be held in the palm of the hand and comprises lower and upper overlying frame members 40, 41 which are pivotally interconnected by a pivot rod 42 carried by a bracket 43 on the frame member 40. This bracket is secured to the frame member 40 at one side only to provide a through space 44 which is open at one side for sidewise feed of strip material between the frame members. A blade 49 is fixedly mounted on the frame member 40 and a blade 50 is pivoted to the frame member 41 on a cross pin 51. The blade 50 engages the inner side of the blade 49 under the action of a torsion spring 54 surrounding the pin 51. The frame members are biased open by a U-shaped spring 59 interposed between the frame member 41 and the cross arm 46 of the bracket 43, the open position being defined by abutment of an end flange 60 of the frame member 41 against the bracket arm 46. In a modification, Figs. 12 to 14 (not shown), the pivot between the frame members is offset sidewise relatively to the blades to provide a through space at right angles to the blades for feed of material to be cut.
Patent GB-685079-A (GB)
Title: Improvements in or relating to the dealkylation of aromatic compounds
IPC: C07C5/367
Filed: 1950-07-06
Abstract: Simultaneous dealkylation of an alkylated aromatic compound and dehydrogenation of an alicyclic hydrocarbon are effected by contacting the compounds, in the vapour phase, at 250-650 DEG , especially 500-600 DEG  C., in the presence of a cracking catalyst, preferably activated carbon.  Hydrogen from the alicyclic hydrocarbon combines with the alkyl group to form a paraffin.  The products should be removed as formed.  The alicyclic hydrocarbons generally have 5 or more alicyclic carbons and are more saturated than the compounds being dealkylated.  Examples are cyclopentane, cyclotetralin, hydrindene, and compounds having unsaturation in the ring or side chain.  Naphthenes give aromatics or cyclo-olefins.  The alkylated aromatic compounds may be benzenoid p  or polycyclic hydrocarbons, e.g. diphenyl naphthalene, anthracene or phenanthrene derivatives.  The carbon used as catalyst may be from vegetable, petroleum or like sources or from pure organic compounds, and activated with steam or other inert gas.  Metallic oxides or salts may be present.  A molar ratio of naphthalene to aromatic compound of about 1 : 1-3 is employed.  The partial pressure of hydrogen should be less than about 150 p.s.i.  Total feed rates are normally 0.1-10 liquid vols./vol./hour.  Fixed or moving catalyst bed or fluidized operation may be employed. Examples relate to the reaction of cyclohexane, cyclopentane, their methyl derivatives, or naphthenic naphthas, with toluene, ethyl benzene, methyl naphthalene, xylenes, C9 aromatic fraction, aromatic kerosene extracts or m, p-cresols, with activated bituminous or coconut charcoal or iron oxide-pumice as catalyst.
