Title: Improvements in the production of colloidal solutions of metal iodides
IPC: A61K9/00
Filed: 1932-06-20
Abstract: Colloidal solutions of metal iodides in oils are obtained by mixing a solution of iodine in oil with a solution of a fatty acid salt or resinate of the metal in oil, preferably in chemically equivalent proportions.  Suitable salts are oleates, stearates, linoleates, palmitates or resinates of metals such as copper, mercury, lead, manganese, zinc, iron or tin.  Suitable oils are olive oil or earth-nut oil, which may contain a small amount of beeswax.  The products are stated to possess disinfectant and therapeutic properties.ALSO:Colloidal solutions of metal iodides in oils, which are stated to possess disinfectant and therapeutic properties, are obtained by mixing a solution of iodine in oil with a solution of a fatty acid salt or resinate of the metal in oil, preferably in chemically equivalent proportions.

Abstract: 1,157,540. Chlorinated phenols. KONINKLIJKE NEDERLANDSCHE ZOUTINDUSTRIE N.V. 17 April, 1967 [12 May, 19661, No. 17544/67. Heading C2C. Pentachlorophenol and lower chlorinated phenols are prepared by treating phenol or a lower chlorinated phenol with hydrochloric acid and/or chlorine and an oxygen-containing gas at a temperature between 100‹ C. and 350‹ C. in the presence of an oxychlorination catalyst. The reaction is preferably carried out by contacting a mixture of hydrochloric acid and an oxygen-containing gas with the phenol in the form of a vapour and passing the mixture over the catalyst, which may be in the form of a fluid or fixed bed. Intermediates, e.g. 2,4,6- trichlorophenol, may be prepared in good yields by adjusting the reaction conditions.

Abstract: 169,783. Blichfeldt, S. H. June 29, 1920. Extrusion machines. - Margarine previously cooled in the form of flakes or granules is compressed into a coherent mass and freed from air by progressively forcing it through one or more cylinders A having constricted outlets D by means of pistons F which also control the feed-openings a<1>. The pressure, normally about 100 lbs, per sq. inch, is governed by the size of the outlets D and by perforated plates d which may be placed near the outlet so as to cause further subdivision and compression of the margarine.

Title: Regulating apparatus for piston pumps with shaft drive and variable length of stroke
IPC: F04B1/06
Filed: 1920-06-30
Abstract: 145,640. Krupp Akt.-Ges., F. Feb. 15, 1917, [Convention date]. Stroke, varying.-In a piston pump driven by a rod B the stroke of the piston is adjusted by a sliding movement of a sleeve D on the rod. The sleeve is connected by a lever E and links e<2>, g<2> to a differential piston G in a cylinder A', one end of which is always open to one end of a cylinder A<8> through a channel a<9>. The liquid is delivered by the pump to a pipe a<2> provided with a non-return valve a', and passes by a pipe a<3> to a casing C containing a valve C<2> controlling the flow and return ports c<4>, c<3> of an hydraulic motor &c. fed by the pump. Normally, the valve C<2> is adjusted by hand to open the ports c<4>, c<3>. The delivery liquid also passes by a pipe a<10> to one end of the cylinder A<8> containing a piston H which is normally pressed to the right by compressed air in a cylinder J. The rod of the piston H has a slot h<2> in which works a roller carried by a lever F pivoted to the pump casing and connected to the rod g<2>. As the delivery pressure rises, the piston H is forced to the left and a collar h<3> on the piston rod moves a lever K connected to a lever P carrying two pins p<1>, p<2> adapted to operate valves Q, R. Movement of the portion H to the left lowers the pin p<1> or raises the pin p<2>, thereby closing the valve Q and opening the valve R. Communication is now opened between the right end of the cylinder A<8> and the right end of cylinder A<7> through a pipe n<9>, chambers n<4>, n<5>, channel n<6>, and pipe n<7>, and the piston G is moved to the left and moves the sleeve D to diminish the pump stroke. When the delivery pressure falls, the piston H moves to the right and releases the lever K so that a spring rod M actuates the lever P to open the valve Q and close the valve R. Communication is then open between the right end of the cylinder A<7> and the suction side of the pump through the pipe n', passage n<6>, chambers n<2>, n<3> and pipe n<8>, and! the pressure in the left end of the cylinder A<7> moves the piston G to the right and increases the pump stroke. If the delivery is interrupted by the valve C<2> being moved to close the ports c<4>, c<3>, the increase of pressure in the cylinder A<8> reduces the stroke to zero, and the valve a<4> closes and cuts off the pump from pressure. The pressure in the cylinder J then moves the piston H to the right to increase the stroke sufficiently to enable the pump to make good the leakage. In a modification, a spring device is arranged between the pins p<1>, p<2> to assist in opening the valves Q, R.

Title: Improvements in or relating to electric lamps
IPC: H01K3/20

Abstract: 1,209,866. Incandescent lamps. FABRIQUES REUNIES DE LAMPES ELECTRIQUES. 8 April, 1969 [11 April, 1968], No. 17897/69. Heading H1F. To maintain the filament support leads 2, 3, 4 of an electric incandescent lamp in position while they are fitted and sealed into the lamp bulb 1, a supporting rod 8 is welded to the leads. After the sealing process the lamp is evacuated and filled with a neutral gas, and a voltage is applied across the lead-in members 9, 10, 11 connected to the filament support leads 2, 3, 4 to cause a current sufficient to melt the supporting rod 8. This current is interrupted as soon as the rod 8 has fused. Alternatively the manufacture of the lamp is completed with the rod in position and the rod fused when the lamp is operated for the first time. In a further embodiment, Fig. 3 (not shown), two supporting rods may be used for greater rigidity and to prevent twisting. The lamp bulb may be of quartz glass and the supporting rod 8 may be of tungsten.

Title: Improvements in the de-washing of hydrocarbon oils
IPC: C10G73/06
Filed: 1933-06-23
Abstract: In dewaxing hydrocarbon oils such as residium stocks, overhead distillates and crude petroleum or shale oils, by admixing with a liquefied normally gaseous solvent, such as liquefied propane, and cooling to crystallize the wax, the rate of crystallization diminishes rapidly when a certain temperature in an example about 20 DEG  F., is reached.  The diminution is prevented during further cooling, by removing solvent by evaporation at such a rate that the proportion of solvent in the oil solvent component is maintained at about that existing at the temperature at which the alteration in the rate of crystallization takes place.  The evaporation is effected by adjusting the pressure on the mixture, preferably in stages. Solvents for colouring matters and asphaltic compounds, such as carbon disulphide sulphur dioxide, methyl chloride or butyl alcohol, may be added to the mixture p  before crystallization.  Chilled solvent may be added to the chilled mixture before separation of the wax in a centrifuge, in order to increase the difference in specific gravity between the wax and the oil-solvent component.
