Title: Sulphonylureas
IPC: C07C311/54
Filed: 1957-09-03
Abstract: Sulphonyl-ureas of the formula RSO2NHCONHR1 in which R and R1 are substituted or unsubstituted alkyl, aryl, alkaryl or aralkyl radicals, are made by reacting a sulphonamide of the general formula RSO2NHM, wherein M is an alkali-metal or one equivalent of an alkaline-earth metal, with a symmetrical urea of the formula R1NHCONHR1, suitably at 75 DEG to 250 DEG C., more preferably at 150 DEG to 170 DEG C. in an inert solvent, and, where the free sulphonyl urea is required, liberating this from the resulting salt by acidification. Suitable starting materials include di- C1-5 alkyl ureas such as di-n-butyl urea and p-toluenesulphonamide or methoxy-, carbethoxy- or halo-phenyl sulphonamides. Specified products include N1-p-toluenesulphonyl -, p - chlorobenzenesulphonyl -, sulphanilyl -, acetylsulphanilyl - and p - nitrobenzenesulphonyl-, N11-butyl urea and N1-p-toluenesulphonyl - N11 - ethyl and N11 - phenyl urea.ALSO:Hypoglycoemic agents comprise sulphonylureas of the formula RSO2NACONHR1, in which R and R1 are substituted or unsubstituted alkyl, aryl, alkaryl or aralkyl radicals (see Group IV (b)).

Title: Reverberatory smelting of copper concentrates
IPC: C22B15/04
Filed: 1966-11-19
Abstract: A reverberatory furnace comprises converting- smelting and slag separation zones B, A, C respectively-metal and slag tapholes 26 at opposite ends with conveyers 31 for introducing the metal concentrate into the smelting zone A so as to form a restricted zone 35 in said zone A, and oxygen lances 36 and 41 projecting through the side walls or roof of the furnace, the tips of said lances being located beneath the surface of the slag layer to cause turbulence. The furnace hearth 19, 18, 20 generally slopes from the slag taphole end to the metal taphole end, so that smelted metal concentrate slowly flows downwards from the hoops 34 in zone A to zone B and finally to the sump 21, while the slag, due to the turbulence of the lances, is forced from zone B through the restricted space into zone C, where it is mixed with suitable reductants 48 which assist in the removal of the metal to the bottom of the slag pool 25. Burners 37 play on the banks of concentrate 34, side burners 50 induce circulation of slag, end burners 52 play on the slag pool 25 and end burners 55 play over a copper reservoir 22. In a modification, Figs. 3 and 4 (not shown), lances are disposed in the side walls and with two charging conveyers on one side the heaps of charge material form a narrow sinuous passage for the slag. Another modification, Fig. 5 (not shown), has two gas offtakes above the ends of the charging conveyers. In another modification, Fig. 6 (not shown), the conveyers feed on to rotary drums and in a final modification, Fig. 7 (not shown), the conveyers drop the charge through roof openings. The furnace may also be L- or U- shaped.
Patent ES-337578-A1 (ES)
Title: Multiphase alternating current dynamoelectric machine stator winding and method of disposing the winding in slots of the stator
IPC: H02K3/12
Filed: 1967-03-04
Abstract: In polyphase stator windings having concentric pole groups there is a tendency for the end-turns of the outermost coils in adjacent pole groups to touch and to subject the insulation at this point to the full line voltage. This danger is overcome by spacing these adjacent end-turns radially of the core and interposing end-turns of other phases. This is achieved by placing one pole-group 1A of one phase at the bottom of the slots and the other pole-group 6A of that phase at the top of the slots. In addition, the remaining pole-groups 2B, 4B and 3C, 5C extend obliquely from one depth to another so that they lie between the end-turns of the first group. This arrangement is arrived at by first inserting coils 1A in the slot-bottoms, then coils 2B partly overlapping 1A, then coils 3C, 4B, 5C and finally 6A at the slot-tops. The turns may be sinusoidally distributed, i.e. the outer concentric coils may have more turns, and may completely fill a slot. The insulation between coils is augmented by sheet insulating elements 71, 72, 73. These elements (Fig. 3, not shown) consist of legs which extend through the slots between coils, and end portions which lie between end-turns. The coils may be preformed or wound in situ. Overload protection is provided by a temperature-sensitive element 77 having a heat-absorbing fin 78 engaging the windings.
Patent ES-339639-A1 (ES)
Title: Foamed Polymers Containing an Isocyanurate Ring Structure
IPC: C08G18/76
Filed: 1967-04-22
Abstract: Foamed polymers containing an isocyanate ring structure are prepared by reacting in the presence of a blowing agent and a catalyst for the polymerization of isocyanates, a polyol of M.W. greater than 300 and a crude diisocyanatodiarylalkene composition containing 5 to 70% by weight of polyisocyanates of functionality greater than two, in such amounts so as to provide at least 1À7 equivalents of isocyanate group for each equivalent of active hydrogen. Preferred diisocyanatodiarylalkane compositions are the diisocyanatodiphenylmethane compositions which may be optionally halogenated. Conventional linear and branch chained polyethers or polyesters are preferably used. The blowing agent may be water and/or inert low boiling liquids especially halogenated hydrocarbons. Catalysts which may be used are strong bases, e.g. quaternary ammonium hydroxides, alkali metal hydroxides and alkoxides, alkali metal salts of carboxylic acids, certain tertiary amines and non-basic metal salts of carboxylic acids, e.g. lead octoate. Mixtures of the above catalysts with conventional catalysts, used in the formation of polyurethanes, may be used. The reaction mixture also may contain surface active agents, plasticizers, flame-retardants, fillers and antioxidants.
Patent ES-346233-A1 (ES)
Title: Miniature crossbar switch with flexible tape selecting means and mechanical latch
IPC: H01H67/26
Filed: 1967-10-19
Abstract: In a cross-bar switch employing mutually orthogonal sets of longitudinally displaceable select and hold bars, the holding bars are spring biased in one direction and have abutment surfaces which engage the movable contacts of the selected sets and bias them in this direction. The selected contacts are thus held closed mechanically. As shown (Fig. 1) the movable contacts are coil springs 2 mounted on a printed circuit board 1 and the fixed contacts are parallel coil springs 18, the turns of which are sufficiently far apart to enable a coil spring 2 to squeeze between them. The select bars 3 are biased towards the right of the figure by links 11 and coil springs 10 and are displaceable to the left by energizing electromagnets 54 attracting their armatures 8. The holding bars are similarly mounted. As shown in Fig. 9, the holding bars 36 to 38 and selecting bars 34, 35 have apertures through which the movable contact springs 39, 40 and 47-50 pass. The holding bars have teeth one per aperture which extend into the apertures and form the abutments. Open contacts at an unselected cross-point in the normal position of the bars are shown at A, A1. To close such contacts the corresponding hold bar 36, 37 or 38 is displaced towards the bottom of the figure by enabling its electromagnet. The corresponding select bar 34 or 35 is displaced to the left by energizing its electromagnet thus moving the movable contacts in front of the abutments. The hold bar is then released causing the movable contacts to be forced into engagement with the fixed contacts as shown at B, B1. The select bar can then be released as indicated at C, C1. The select and hold bars are made of light material, e.g. polyester ribbon. Each cross-bar assembly is closed by a transparent plastics cover 19.

Abstract: A more compact high energy loss device is provided having a series of uniquely formed multiturn labyrinth assemblies which reduce the pressure of a fluid flowing therethrough. The inlet of the labyrinth assemblies is formed according to a substantially circular configuration to have a predetermined inlet area while the outlet is formed according to a substantially scalloped configuration to provide an outlet area greater than the inlet area. The scalloped configuration of the outlet yields an outlet area which is also greater than if the outlet were of circular configuration. The scalloped outlet configuration also makes the labyrinth assembly less susceptible to circumferential thermal stresses resulting from high temperature fluids passing through the device producing high temperature inlet conditions and low temperature outlet conditions.
