Title: Improved manufacture of metallic cyanamides
IPC: C01C3/18
Filed: 1930-10-24
Abstract: Cyanamides or mixtures of cyanamides of the divalent metals are prepared by treating the corresponding oxides at a temperature of a dull red heat to red heat and at atmospheric pressure with a gaseous mixture of ammonia and carbon dioxide.  Gases containing ammonia and carbon dioxide in admixture with hydrocarbons can also be employed. Lime sludge from the preparation of acetylene, the decomposition of crude calcium cyanamide or the like may be used as the oxide.  The metallic oxides may be mixed with substances which are known to facilitate nitrogenization such as halides, cyanamides and also oxides or carbonates of the alkali metals. The mixture of ammonia and carbon dioxide before its reaction with the oxide may be passed over catalysts, especially those having an imide forming or water-removing action such as alumina, silica, crude calcium cyanamide, oxides of rare earth metals, copper, manganese, alloys of these metals, carbon, wood charcoal, active charcoal and the like.  These catalysts are preferably mounted on porous bodies, especially on such as are themselves catalytic such as kieselguhr, brimstone or wood charcoal. The walls of the reaction chamber may be lined with the above catalysts; or they may be mixed with the reacting metallic oxide as may be embedded therein in layers.  Metals which promote the decomposition of ammonia are excluded from the reaction chambers. The rate of flow of the ammonia-carbon dioxide mixture supplied to the reaction chamber should be so regulated that the water vapours content of the furnace gases lies below a certain limit.  If the product is to be used as a fertilizer, subsequent treatment of the product with carbon dioxide is preferable to remove any alkalinity.

Title: Improvements in or relating to process for refining hydrocarbon oils
Inventor: KRAUSE JACK H
IPC: C10G21/10
Filed: 1953-11-20
Abstract: Hydrocarbon oils boiling within the range of about 300-650 DEG F and containing mercaptans and phenols, are refined by solvent extracting with liquid SO2 at a temperature below about 35 DEG F., and then treating the SO2-free raffinate with free oxygen at a temperature below about 120 DEG F., in the presence of a catalyst comprising cupric chloride, water and an inert carrier, to produce a substantially mercaptan-free oil.  The hydrocarbon oils may be straight-run petroleum fraction or may be derived from the thermal or catalytic cracking, or the hydrodesulphurization, of a petroleum fraction; the oils may be kerosenes, heated oils, burning oils, furnace oils, diesel fuels or jet fuels.  Examples of suitable inert carriers are Fullers' earth, silica gel, diatomaceous earth, pumice, charcoal, coke and alumina.  Apparatus is described in which a virgin petroleum heater oil is de-aerated, for example by vacuum treatment, dehydrated, for example by contact with calcium chloride, rock salt, magnesium silicate or alumina gel or by vacuum distillation and extracted with liquid SO2 at 10 DEG F.  The extract phase thus obtained contains phenols and aromatic hydrocarbons.  The extract and raffinate phases are freed of SO2 and the latter is purified and returned for re-use.  The raffinate is washed with aqueous caustic alkali to remove traces of SO2 and then freed from traces of caustic alkali solution, for example by contact with rock salt, excelsior, fibre glass or steel wool.  Air or oxygen is injected into the SO2-free raffinate and a slurry is made with a portion of the raffinate and a catalyst made up of about 20 per cent cupric chloride about 12 per cent water and the remainder attapulgus clay.  The main body of oxygenated raffinate is contacted with the catalyst slurry at 90 DEG F., freed of catalyst, water-washed and dehydrated by contact with rock salt.  N, N1-disalicylidene-1, 2-diamino-propane may be added as metal deactivator to the refined oil thus obtained.  For comparison purposes, the effect of deferring the extraction with liquid SO2 until after the treatment with oxygen in the presence of the cupric chloride-containing catalyst is described.

Title: Process for making foils of decreased brittleness from polymerisation products of vinyl chloride
IPC: B32B27/00
Filed: 1934-11-12
Abstract: Foils are produced from polymerized vinyl chloride by rolling the polymerized product to a film on heated rollers without the employment of solvents, and hot pressing the film obtained.  If desired the rolled film may be stretched in a direction perpendicular to that of rolling and then pressed.  In a modification a plurality of films obtained by rolling, with or without transverse stretching, are superposed with their directions of rolling perpendicular or at an angle to one another, and are then hot pressed to weld the films together.  It is stated that the brittleness of the films obtained is extensively diminished in all directions.  The strength of the films can be further increased by adding to the hot plastic polymerisation product substances such as condensation products of ethylene oxide with higher alcohols (octodecyl, stearyl, or oleyl alcohol), stearic acid ethanolamide, stearic acid ethanolamide ester, wool fat alcohols, caoutchouc, hydrocaoutchouc, glycerine, and glycerine ether alcohol.  Proportions of about 1 per cent are used.  Suitable polymerisation products for use in the process are polymerized vinyl chloride, after-chlorinated polyvinyl chloride, and mixed polymerisates of vinyl chloride and arylic acid esters or of vinyl chloride and vinyl acetate.

Patent GB-331902-A (GB)
Abstract: 331,902. Benzing, F. E. March 14. 1929. Factory and like time-recorders; card-type.-In an apparatus adapted to stamp working times on a card the time-adding wheels are controlled, as regards their actuation by the pawl-carrying oscillating lever h, by means of a shaped disc k which is variably positioned by the lever according to the time of day. The disc is connected by a bolt l with an arm m adapted to rest on a cam disc B rotated once per day. The disc k bears type at o<1> to distinguish ordinary time and overtime, and is toothed at o and p and shaped at q and r to co-operate respectively with pawls n and s carried by the lever h. In the position 'shown in Figs. 1 and 1a, the mechanism is recording ordinary working times. The lever m occupies its lowest position and the bolt l connecting the lever with the control disc k causes this disc to assume such a position as-to permit the engagement of the pawl-rake s with the timewheels. The ordinary feeding action of the pawlrake s therefore takes place and the disc can print a circle denoting ordinary times. When the meal period is reached, the lever m when raised by the lever h is kept up by resting on a cam surface y and consequently the disc k is positioned as in Fig. 8 so as to be driven by pawl n and by its step r to mask the minute ratchet-wheel and therefore render the pawl-rake s ineffective. When the overtime period z is reached the lever m and disc k occupy an intermediate position (Fig. 9) so that the pawl n engages the tooth o and the step q permits only a limited engagement of the rake s that is with the minute wheel and first hour wheel the second hour wheel accordingly remaining stationary. In any stamping in this condition a sign + is printed on the card to indicate overtime.
