Title: Improvements in or relating to the manufacture of spray-dried detergents
IPC: C11D11/02
Filed: 1945-05-03
Abstract: Spray dried soaps and non-soapy synthetic detergents are subjected to the action of steam alone or to the action of steam in combination with a liquid such as water or a solution of a coating or modifying agent, while tumbling or otherwise agitating the material, in order to reduce fines and lumping tendency of the material in hot water and also to increase the apparent specific gravity of the material.  The material may be agitated by means of a rotating drum, tumbler, vibrating conveyor belt &c. during the steaming operation, the temperature of the atmosphere being generally 120 DEG F. to 220 DEG F.  The particles may be treated simultaneously or successively with steam and the liquid such as water or solution of a coating, plasticizing or modifying agent. Thus there may be used moist steam, or a mixture of steam with the vapours or atomized particles of plasticizers such as glycerine, glycol, mineral oil, and water-soluble sulphonated oils.  The material is finally dried, agitation being preferably continued to reduce the total moisture content, preferably to that of the original material, warm dry air or inert gas being suitably used. The non-soapy synthetic detergents specified comprise the water-soluble salts of organic substituted, poly-basic, oxygen-containing inorganic acids including sulphates, sulphonates, borates, sulpho-borates, ortho-tetra-, pyro-, and polymetaphosphates, and phosphites.  The initial spray-dried p detergents may also contain the usual builders, buffers &c.  An actual non-soapy synthetic detergent exemplified comprises the Na salt of sulphuric acid ester of coconut oil fatty acid monoglycerides.

Title: A method and apparatus for determining the quantity of hydrogen in metal samples
IPC: G01N7/14
Filed: 1957-04-08
Abstract: <PICT:0827018/III/1> <PICT:0827018/III/2> The quantity of hydrogen in metal samples, such as titanium, zirconium, uranium and alloys rich in these metals is characterized by the steps of evacuating an oven and gas collection system of known volume to a pressure below 10-4 mm. Hg. absolute, then sealing the gas collection system from the evacuation means, adding to a crucible contained within the oven a metal sample which evolves only hydrogen when heated to a temperature below its melting point, heating the metal sample to a temperature which is sufficiently high to evolve only hydrogen but which is below the melting point of the sample, collecting the evolved hydrogen in the gas collection system, measuring the pressure of the hydrogen in the gas collection system, then opening the collection system to the evacuating means to remove the collected hydrogen, moving the crucible into a chamber of substantially greater cross-section than the oven, tipping the crucible in the latter chamber to drop the metal sample which has been analysed into a spent sample collection chamber, moving the empty crucible back to the oven, sealing the gas collection system from the evacuating means, and repeating the procedure until all the metal samples have been analysed.  The crucible may be thoria-coated tantalum or thoria-coated molybdenum and the sample may be added to the crucible in a perforated tantalum capsule. Measurement is made by means of McLeod or Pirani gauge and the measurement may be recorded automatically.  Samples of known weight are loaded into sample arm 14.  The mercury is lowered from cut-offs 50 and 52 and the mercury diffusion pump and oil diffusion pump 34 and 60 and mechanical pump 62 are started so as to evacuate the whole system to below 10-4 mm. of mercury absolute.  The mercury from reservoirs 56 and 58 is raised into cut-offs 50 and 52 so as to provide a gas collection system bonded by mercury diffusion pump 34 and mercury cut-off 50.  The sample passes through chambers 10a and 10b through the hollow centring cylinder 26 and into crucible 22 preferably controlled by magnetic means.  The crucible 22 is heated by means of an induction heating coil 24 to a temperature below the melting point of a metal so that only hydrogen evolution will take place. The arrangement of the centring cylinder and counter-weights allows for the sample to be removed from the crucible and replaced by another sample.

Title: Improvements in or relating to the recovery of phenol from phenol-brine mixtures by distillation
IPC: C07C37/74
Filed: 1943-07-13
Abstract: <PICT:0587568/III/1> Phenol is recovered from salt mixture obtained in the synthetic production of phenol, e.g., by the chlorobenzene process, by allowing the mixture to settle out into two layers the upper of which is rich in phenol while the lower is rich in brine, separating the layers, evaporating the upper phenol layer to separate out the salt and fractionating the salt free phenol to recover phenol as a bottoms product and water as a top product. The lower layer is stripped to remove phenol as vapor which is added to the salt free phenol undergoing fractionation.  The phenolbrine mixture is fed to separator 12.  The upper phenol layer is fed to evaporator 32 from which salt is removed through 34 while the phenol vapours are passed to tower 37.  The lower brine layer is stripped in tower 16 and the condensate separated into phenol and water layers in separator 26 the phenol layer being fed through line 26 to tower 37 while the water layer is refluxed to tower 16.  In a modification the phenol layer is returned to the separator 12.  The fractionation in tower 37 is preferably effected in presence of a water entrainer, e.g., toluene charged to the system through line 46.  The tower 16 may be operated at increased pressure, viz., 3 atmospheres.ALSO:Phenol is recovered from salt mixture obtained in the synthetic production of phenol, by allowing the mixture to settle out into two layers, the upper one of which is rich in phenol, while the lower is rich in brine, separating the <PICT:0587568/IV/1> layers, evaporating the upper phenol layer to separate out the salt and fractionating the salt-free phenol to recover phenol as a bottoms product and water as a top product.

Filed: 1954-04-20
Abstract: 784,515. Discharge apparatus. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 20, 1954 [April 16, 1953], No. 11413/54. Class 39(1). An arrangement for switching on and off a direct current circuit 4, 6, Fig. 1, includes an anode 1, a cathode 2 and a third electrode 3 insulated from the anode and cathode and brought (when the switch is operated) to substantially the same potential as the cathode ; when a control voltage source 5 is connected between anode and cathode it co-operates with a magnetic field perpendicular to the paper so as to prevent electron flow from the cathode from reaching the anode and to cause it to impinge on the electrode 3 and thus complete the circuit 4, 6. To increase the current capacity a secondaryelectron-emissive electrode 7, Fig. 4, connected to the cathode, may be interposed between the cathode and electrode 3. In this form also the anode proper 1 is a short sector mounted within a conductive auxiliary anode 10 at constant positive potential. The circuits 5 and 4 are shown coupled through pulse transformers 15, 16. The whole arrangement may be everted, Fig. 3 (not shown), the anode 1 being the central electrode and cathode 1 and electrode 3 being sectorally mounted in a surrounding electrode 7. The electron motion, instead of being wholly circumferential may be partly axial, electrodes 7, Fig. 9, being mounted on either side of electrode 3 and within cylindrical anode 1. The electrodes 7 are slightly conical to give the necessary axial component of field; for the same purpose, the plane of separation between electrodes 3, 7 may be inclined to the axis. The distance between electrode 3 and the anode may, in either of the forms described, be varied according to a law designed to improve the electron path ; this may involve shaping either or both of the electrodes.
