Title: Manufacture of condensation products containing nitrogen
IPC: C07D251/08
Filed: 1931-11-06
Abstract: Condensation products containing nitrogen, which are probably symmetrical triazine derivatives, are manufactured by causing a compound of an aldehyde containing more than one carbon atom and ammonia to react with a compound or a mixture of compounds containing two amino groups each of which may contain one substituent and both of which are united to C = O or C = NH.  The condensation may be performed by fusing together the reaction components or by heating them in the presence of a solvent, such as water or an organic solvent.  The water formed by the condensation process may, if desired, be removed, e.g. by adding an organic solvent which forms with water an azeotropic mixture boiling between 50 and 90 DEG  C. such as benzene, or by using in the presence of the solvent a water absorbing agent such as finely pulverized sodium sulphate or anhydrous borax.  The products may be employed as assistants in the textile industry, for the synthesis of remedies or as fungicides and insecticides.  In examples: (1) urea and acetaldehyde ammonia are heated in aqueous solution to give a product of the empirical formula C5H11ON3 and of the probable constitution <FORM:0376603/IV/1> the acetaldehyde ammonia may be replaced by propionaldehyde ammonia or crotonaldehyde ammonia; (2) guanidine nitrate and acetaldehyde ammonia are heated in aqueous solution; (3) urea and butyraldehyde ammonia are heated in aqueous solution; (4) urea and aldol ammonia are heated in aqueous solution; (5) symmetrical dimethylurea and acetaldehyde ammonia are heated in methyl alcohol with finely pulverized anhydrous sodium sulphate; the dimethylurea may be replaced by other symmetrically substituted ureas such as diethylurea, ethylpropylurea (obtainable from ethylamine and propyl isocyanate), diphenylurea or ethylphenylurea; (6) urea and phenylacetaldehyde ammonia are heated in benzene, the water produced being distilled off with the benzene as an azeotropic mixture. Specification 366,524 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of compounds of aldehydes in general with ammonia or methylamine and of compounds containing two amino groups attached to the group C = S.  Additional examples describe the condensation of thiourea with acetaldehyde ammonia in aqueous solution and of urea with the reaction product of acetaldehyde and methylamine in acetone with the addition of finely pulverized anhydrous borax.  This subject-matter does not appear in the Specification as accepted.

A sheet-feeding apparatus which is described in connection with the feeding of steel sheets to the conveying mechanism described in Specification 670,311, [Group XXX], is constructed with a pack conveyer A comprising rollers 25 for ad vancing packs 23 of sheets supported on skids 24 into engagement with rollers 26 carried by a pile-raising mechanism comprising a plunger 27 which is raised intermittently by hydraulic pressure under control of a micro switch which is operated when the top of the pile is low. The rollers 26 are mounted in a carriage comprising. rollers 30, the carriage being pressed by a fluidpressure operated plunger 35, Fig. 3, to register the pile against a guide which controls the transverse position of the sheets. To enable sheets of different lengths to be fed the pile is registered longitudinally by an adjustable stop 49, Fig. 2, which is pivotally mounted and controlled by a snap-action mechanism which moves the stop to and from active position by means of stops arranged on the pile elevator. To hold the pile on the elevator two of the supporting rollers 26 are adapted to be locked in position by sliding brakes 36, 37, Fig. 6, which are operated by cam surfaces 38, 39, on a sliding yoke member 40 operated by a bell crank 41 which is actuated by a fixed surface 44 as the pile elevator is lowered to receive a new pile. The yoke 40 is actuated by a spring 46 to put on the brakes. The sheets are separated from the pile by oscillating suction separators 63, Fig. 12, which engage the pile under spring action so as to adapt them to variations of pile height. The upward movements of the pile elevator are controlled by a switch 72 operated by a lever arm 73 with a roller 74 which when engaged by the pile stops further motion of the elevator. A micro switch s, operated by a lever s' when engaged by a plunger head s<SP>6</SP> carried by the suction device, causes the elevator to operate if the pile gets too low. The separator, or a number of separators, carries or carry the sheet to rollers 69, 70, Fig. 3, from which the sheets pass to conveyers as described in Specification 670,311, [Group XXX], which include a magnetic band to the underside of which the sheets are held magnetically. To enable the feed to continue while the bottom part 23, Fig. 10, of the pile is being fed three supporting devices each comprising a cylinder 75 and piston 76 fitted with a pivoted supporting finger 77, are arranged so that the fingers pass through slotted guide plates 78 so as to hold the pile while the elevator is depressed for further charging. The fingers may be swung away from the pack during normal action of the elevator.

Title: Improvements in or relating to expansion joints
IPC: E01C11/10
Filed: 1938-11-02
Abstract: 506,890. Sponge rubber. INTERNATIONAL LATEX PROCESSES, Ltd. Nov. 2, 1938, No. 31695. Convention date, Nov. 6, 1937. Drawings to Specification,. [Class 70] [Also in Group X] A method of forming an expansion joint in a space' between two spaced constructional members, such as paving slabs, consists in filling the space, at least partially, with an uncoagulated latex foam, and allowing the foam to form a rubber sponge in situ. The term "latex " is stated to designate coagulable aqueous dispersions of elastic materials, including artificial, dispersions of rubber, as well as natural latex. The foam is preferably compounded with a material, such as aluminium silico fluoride, a water emulsion of pine tar, or a polyvalent metal salt, to produce delayed coagulation whereby the foam after being poured into the joint space will gel on standing. The latex composition also contains a low-temperature accelerator, such as diamyl ammonium diamyl dithiocarbamate emulsion, so that the sponge will vulcanize under atmospheric conditions. In one example, a latex composition, which consists of centrifuged latex, potassium hydroxide solution, sulphur paste, diamyl ammonium diamyl dithiocarbamate emulsion, zinc oxide paste, and ammonium linoleate solution, is whipped to a foam in a whipping machine, an eight per cent solution of ammonium silico fluoride is added, and the compound then poured into the joint space. The foam may, alternatively, be made by a chemical process in which an acid is added to a latex composition containing a carbonate whereby carbon dioxide gas is generated to form the foam. The latexcomposition, in this case, may consist of centrifuged latex, the material known by the Registered Trade Mark " Emulphor O " (the reaction product of ethylene oxide and a higher alcohol), diamyl ammonium diamyl dithiocarbamate emulsion, zinc, oxide paste, " Aqualoid " (a stabilized hydrate of vegetable lecithin), and dry ammonium carbonate ; the foaming agent consists of glacial acetic acid; ammonium acetate, " Emulphor 0 " and water. The " Emulphor O " . and " Aqualoid" " are added to prevent coagulation of the latex on addition of the acetic acid. A twenty per cent solution of ammonium silico-fluoride may be added to the foam to act as a delayed coagulant. If desired, the latex compound may be made heat-sensitive by the addition of polyvalent metal salts, disubstituted guanidines, or an ammonium salt of a strong acid and zinc oxide. In the case of a heat-sensitive latex which is-not coagulable on standing at normal temperatures, the foam may be heated by playing live steam on the poured joint in order to produce more or less immediate gelling.
