Title: Improvements relating to heterocyclic nitrogen compounds and their use
IPC: C07D233/44
Filed: 1957-12-24
Abstract: The invention comprises compounds of the formula:  <FORM:0869181/IV (b)/1> where A is a saturated hydrocarbon radical bound at the two nitrogen atoms by a ,b - or a ,g ..-carbon atoms, R1 is a possibly substituted benzyl radical, and R2 is hydrogen, or an aliphatic, araliphatic or cyclohexyl radical; either R1 or R2 containing, or R2 being, a lipophilic aliphatic radical.  The group A may be aliphatic or cycloaliphatic.  These compounds may be prepared by reacting a diamine of formula R1-NH-A-NH-R2 with a cyanogen halide, advantageously in an inert organic solvent and heating if necessary, and liberating the base with alkali.  Lists of suitable diamines are given, including compounds in which the benzyl radical is substituted by chloro, hydroxy, alkyl and methoxy groups.  In a modification, a cyanogen halide is reacted with a diamine of formula NH2-A-NH-R, where R is one of R1 and R2, and introducing the other N-substituent into the product by alkylation or aralkylation.  In a second modification where R1 is benzyl substituted by lipophilic groups and R2 is hydrogen, a diamine NH2-A-NH2 is reacted with a cyanogen halide and the product is reacted with about the stoichiometrical amount of a suitable aralkylating agent.  The compounds of the invention form salts with inorganic and organic acids.  The starting diamines may be prepared by (i) esterifying a,b - or a,g  aminoalcohols with e.g. HCl or H2SO4, alkylating or benzylating at the nitrogen, and treating with ammonia or an amine; (ii) reacting di-primary a,b - or a-g ..- diamino-alkanes or cycloalkanes, in which one amino group may be protected by acylation, with reactive alkyl, cyclohexyl or benzyl compounds; (iii) reducing the Schiff's bases obtained from diamines and an aldehyde.  The compounds of the invention have biocidal activity (see Group VI).  Reference has been directed by the Comptroller to Specification 765,547.ALSO:Biocidal compositions contain as active ingredient a compound of formula <FORM:0869181/VI/1> where A is a saturated hydrocarbon radical bound at the two nitrogen atoms by a , b - or a ,g -carbon atoms, R1 is a possibly substituted benzyl radical, and R2 is hydrogen or an aliphatic, araliphatic or cyclohexyl radical; either R1 or R2 containing, or R2 being, a lipophilic aliphatic radical.  The group A may be aliphatic or cycloaliphatic. Specified substituents on R1 include halogen, alkyl, hydroxy and methoxy.  The compositions may be powders, dispersions or solutions, and may contain inert carriers or fillers, capillary active agents, cleansing agents, cosmetics, medicinal preparations or other biocidal agents.  The compositions may be based on organic solvents, or aqueous solutions of the salts of the above compounds may be used.  The compounds have bactericidal or bacteriostatic, fungicidal and algaecidal activity.  Reference has been directed by the Comptroller to Specification 765,547.

Abstract: 895,021. Machinery safety devices. WITTON ELECTRONICS Ltd., and BANKS, C. H. Dec. 23, 1958 [Dec. 27, 1957], No. 40175/57. Class 80 (4). [Also in Groups XXX and XXXVII] In a safety device for a conveyer or other machine wherein movement of a trip wire 2, which may be supported by springs 3 to extend along the length of the machine, actuates a switch 10 to stop the machine and/or to give a warning signal, the switch mechanism is contained in a fixed casing 7 adjacent a magnet 6 carried by the trip wire 2, and comprises a mercury switch 10 on a pivoted arm 8 carrying a magnet 9, the magnet 9 being normally attracted by the magnet 6 to the position shown. Movement of the trip wire 2 displaces the magnet 6 towards a position in which it repels the magnet 9 allowing the arm 8 to fall and actuate the switch 10. The wire 2 may act to prevent a person approaching too close to a dangerous part or may be used as an emergency stop control. After the arm 8 has fallen it is reset by movement of a lever 11. The casing 7 may be of aluminium and may have soft iron polepieces in its wall. The magnet 9 is mounted on the arm 8 by a pivoted stirrup, allowing it to seat correctly against the casing wall. The magnets may be permanent or electromagnets. Where the wire 2 is inclined, rather than horizontal, pulley or lever arrangements may be used to permit the casing 7 to be horizontal or alternatively, Fig. 3 (not shown), the casing may be correspondingly inclined and the mercury switch be carried by a disc which is angularly adjustable about a pivot on the arm to bring the switch into a horizontal position.

Steering linkage responsive to the lateral swinging of the frame in use connects the tractor to the wheel 34 and comprises a motion transmitting member, e.g. lever 63 pivoted intermediate its ends to the frame on bearings 62, and a link 66 which is connected to the wheel, as shown by arm 38 and spindle 33, and to the lever 63 on a pivot axis 64 which when the rational plane of the wheel is parallel to the direction of travel is coaxial or substantially coaxial with the pivot axis of the arm 28 so that the steering of the plough is not affected when the height of the plough is changed. The motion transmitting means, lever 63, may be connectable to the tractor by means of a second line 54 of adjustable length which is pivotally connected to arm 52 fixed to pivot pin 18 itself fixed on plates 17 mounted on draw bar 14. An adjustable stop 46-50 on the frame engages the arm 28 and determines the working depth of the plough. A strengthening truss rod 25 is also shown.

Abstract: 918,860. Transistor amplifiers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 27, 1959 [Dec. 2, 1958], No. 40417/59. Class 40 (6). In a low-noise transistor amplifier the working point of transistor 1 having a base resistor 5 is stabilized by the collector direct current of a later transistor 2 conducted by way of the emitter-collector path of transistor 1, transistor 2 being stabilized by means of negative feedback in emitter resistor 6 and by voltage divider 7, 8. With such an arrangement the emitter direct current variations occurring in transistor 1 correspond to the direct current variations in transistor 2 which latter variations remain within permissible limits. In a further embodiment, Fig. 2 (not shown), a third transistor is connected beyond transistor 2, the base resistor 5 of transistor 1 being connected to the collector of the third transistor so as to produce negative feed-back. The third transistor may be operated in common collector arrangement in order that the amplifier may be connected to a cable.

A process for the production of spheroidal graphite cast iron comprises heating iron ore with a reducing agent to form molten iron, adding to the molten iron a spheroidizing agent, and casting the iron. As shown, iron ore, carbonaceous reducing agent, and slag-forming materials are heated in an arc furnace 10 to reduce the ore to molten metal which may be tapped into a ladle 40 containing a spheroidizing reagent and then cast into moulds 45. The metal from the furnace 10 may be transferred to a refining furnace 20 to which an addition of remelted metal from a furnace 30 may be made, before tapping to the ladle 40. The charge for the reducing furnace 10 may be preheated. It is stated that the process prevents contamination of the metal by sulphur and other deleterious substances obtained from the fuel and the cupola in the usual process for the production of cast iron.
