Title: Sulphonyl dicyandiamides and methods for their preparation
IPC: C07C311/64
Filed: 1943-04-12
Abstract: A sulphonyl dicyandiamide is prepared by reaction of an aliphatic or aromatic sulphonyl halide with dicyandiamide in the presence of an acid-binding agent, such as alkali metal hydroxide. The aliphatic radical may be a lower or higher alkyl or alicyclic radical and may be substituted by hydroxy, amino, carboxyl or the like.  Aromatic radicals include phenyl and naphthyl which may contain alkyl, alkoxy, amino, nitro or hydroxy substituents.  Many are specified. Preferably, a benzene sulphonyl halide substituted in the para-position by an amino or substituted amino group, such as alkyl-, aralkyl-, aryl-, hydroxyl-, aldose- and sodium formaldehyde sulphoxylateamino, or a group reducible to amino such as nitro and azo, or acylamino, convertible to amino by hydrolysis, is used. Sulphonyl chlorides or bromides may be reacted with the dicyandiamide in the presence of aqueous alkali and a non-hydroxylated water-miscible solvent such as acetone or dioxane.  The products are intermediates for azo-dyes, resins and pharmaceuticals, especially such compounds as sulphanilylguanidine.  Sulphonyl dicyandiamides specified include the following: ethyl, hexyl, decyl, dodecyl, hexadecyl, octadecyl, 2-ethylhexyl, isopropyl, secondary and tertiary butyl and amyl, a ,a -dimethylhexyl, cyclohexyl, cyclopentyl, cyclohexylmethyl, b -cyclohexylethyl, a -cyclohexylpropyl, those of alicyclic compounds derived from petroleum, p-toluene, p - carboxybenzene, m - nitrobenzene, p-brombenzene, p-methoxybenzene, a - or b -naphthalene and a -5-sulpho-naphthalene.  The products are isolated as alkali salts or the free acids and may be reacted with salts of, for example, barium, lead or mercury or of amines such as ethylamine, dibutylamine, dodecylamine or pyridine, or with metal oxides or hydroxides, or free amines to form the metal or amine salts.  In examples: (1) benzenesulphonyl chloride and aqueous casutic potash are added to a mixture of dicyandiamide, acetone, water and caustic potash at 25 DEG  C., the mixture acidified with acetic acid, and the solid filtered; (2) crude n-butylsulphonyl halides, prepared from n-butyl isothiourea hydrobromide and chlorine are reacted similarly at 15-20 DEG  C.; (3) reaction is effected as in (1), a solution of benzenesulphonyl chloride in acetone being added at 15-20 DEG  C.; (4) p-nitrobenzene sulphonyl chloride is employed; (5) p-acetylaminobenzene sulphonyl chloride is used.  Other acyl derivatives, such as propionyl, butyryl, decanoyl, benzoyl, furoyl and nicotinyl may be substituted therefor; (6) acetylsulphanilyl dicyandiamide prepared as in (5) is refluxed with caustic soda to hydrolyse it to the corresponding sulphanilyl compound.

Abstract: 263,347. Dalgity, W. March 3, 1926. Road signals. - A signalling device for controlling road-traffic by automatically alternating the signals at regular intervals comprises visible signalling means operatively connected to a tank having two compartments which are filled alternately, thereby rocking this tank periodically to actuate the signals. On the floor 5 of the base of the hollow tower 1 is a support 6 on which is pivoted a tank 7 rocking in a vertical plane and arranged diagonally of the base of the tower. This tank is shaped as shown in Fig. 4 having two compartments 7<b>, 7<c>, outlet cocks 7e, Fig. 1, and eyes 7d to which are attached chains &c. 13. One compartment at a time is filled from the cock 10 and when sufficient water has entered this compartment the tank rocks to operate the chains 13, and the compartment just filled empties through its outlet 7<e>, the other compartment now being under the cock 10. Four shutters 12<a>, 12<b>, 12<c>, and 12<d> have " stop " and clear " signs on them adapted to show through four openings 11 in the cubical head of the tower. These shutters are attached to one another in pairs 12a, 12b, and 12<c>, 12<d>, each pair being attached to a chain 13. If on one shutter (12<a>, 12d) of each pair the word " stop " is above the word " clear, " then on the other shutter of each pair clear " is above " stop." When one pair of shutters is raised the other is lowered; thus the correct corresponding signals will appear on opposite faces of the tower. The shutters may be transparent and illuminated or semaphares may be used. The rate at which the tank oscillates may be varied by adjusting the cocks 10 and 7<e>.

Title: Plastics charging apparatus
IPC: B29C48/04
Filed: 1974-02-11
Abstract: 1450468 Synchronlsing extrusion cutting means H-C INDUSTRIES Inc 11 Feb 1974 06097/74 Heading B5A A rotary conveyer 10, conveys crown caps 12 for bottles beneath an extruder 14 from which an extruder plastics rod 16 is successively cut, by means 18, 20, to drop as slugs into sequential caps 12 for subsequent moulding as a liner to each cap, and the time at which cutting is effected, at a constant conveying rate, is adjustable whilst the apparatus is operating to enable the slugs to be dropped into the centres of the caps. The extruder 14 may be inclined, or vertical as shown, and the cutting is effected by the co-operation of blades 18, 20 which contra-rotate on shafts 22, 24, and are cooled by water circulated through the shafts 22, 24 by pipes 26, 28, and 29. The conveyer and cutters are driven either from separate but synchronised motors, or as shown from a same electric motor 30 from which a pinion 36 rotates the conveyer 10 at a gear wheel 40, and a wheel 44 rotates the blades 18, 20, via a belt or chain 46 engaging wheels 72, 74 respectively on the cutter shafts 22, 24. The belt 46 passes around idlers 52, 54 which are mounted to a member 56 for simultaneous displacement, in either horizontal direction, by means of rack teeth 58 actuated by pinions 60, 64 from a knob 66. Such horizontal displacement maintains the same rates of cutting and conveying, whilst altering in opposite senses the lengths of belt 46 respectively on the driving and return run between the wheel 44 and wheels 72, 74, and hence advances or delays the cutting by the blades 18, 20 relative to the caps 12 being conveyed therebelow. To vary the orientation in which the slugs are received in the caps 12, the impelling action of the blades 18, 20, may also be altered by advancing or delaying the rotational position of the blade 18 relative to the blade 20. Such alteration is effected by horizontal displacement of an idler wheel 70 over which the belt 46 passes, the displacement causing rotation of wheel 74 relative to wheel 72 due to a resilient loading on the belt 46, provided by the idler 52 being mounted to the member 56 by a spring 57.

Filed: 1964-02-14
Abstract: A glass-ceramic body, for use as a barrier layer capacitor and having an interior portion which is chemically reduced so as to be electrically conductive and surface portions oxidized to be electrically non-conductive, is made by melting a glass batch comprising, by weight 5-15% SiO2, 5-15% Al2O3 and 70-90% BaO + TiO2, the ratio SiO2 : Al2O3 being from 3 : 1 to 1 : 3 and the molar ration BaO : TiO2 being from 0.90 : 1 to 1.2 : 1, simultaneously cooling the melt below its transformation point and shaping a glass body therefrom, thereafter exposing the glass body to a temperature of from 850 DEG  to 1250 DEG  C., under reducing conditions, for a time sufficient to attain the desired reduced semi-crystalline body, subsequently exposing the reduced glass-ceramic body to a temperature of from 700 DEG  to 1050 DEG  C. in an oxidizing atmosphere so as to oxidize the surface portion, and finally cooling the body.  The glassceramic body formed in this way has BaTiO3 crystals comprising at least 30% by weight of the body which are all finer than 2 microns in diameter.  In one particular example of producing such a body the glass batch is melted, shaped and cooled to room temperature.  The temperature is then raised at 200 DEG  C. per hour to 1050 DEG  C. and maintained there for 4 hours, and then raised at 200 DEG  C. to 1150 DEG  C. and maintained there for 1/2 hour, subsequently the article being cooled at 400 DEG  C./hour to room temperature, all these steps being effected in the presence of dry hydrogen.  The hydrogen is then replaced by air and the temperature raised at 200 DEG  C./minute to 910 DEG  C., held there for three minutes and then lowered at 400 DEG  C./minute to room temperature.  The crystallization time is from 1/4 -8 hours, and the oxidation time 1 second to 1 hour. The heating rate before crystallization should not exceed 500 DEG  C./hour.  Fluorine is present in quantities less than 2% to aid melting.  The oxides of Ca, Cd, Cu, Mn, P, Pb, Sr, Zn and Zr may be added, the total not exceeding 10% by weight of the batch. Specifications 829,557 and 905,253 are referred to.
