Abstract: A compound of formula <FORM:0904415/IV(a)/1> where R is a substituted or unsubstituted aryl group, A is an alkyl group and B is hydrogen or alkyl (not more than two Bs standing for alkyl groups) is used as an antiozonant in an amount between 0,25 and 5% to stabilize polymers of ethylene, propylene, isobutylene, styrene, vinyl chloride, butadiene, isoprene, chloroprene and copolymers of butadiene with acrylonitrile, styrene and methyl methacrylate.  A may be methyl, ethyl, n-propyl, iso-propyl, sec-butyl, n-heptyl or n-octyl.  R may be phenyl, a - or b -naphthyl or o-, m- or p-tolyl, 2:4-xylyl, 2:6-xylyl, o-, m- or p-chlorophenyl, p-methoxy-or ethoxy-phenyl. If desired the aryl groups from two molecules may be linked through a methylene group. The Provisional Specification discloses the use of a compound of formula <FORM:0904415/IV(a)/2> where R, A and B are as before and X is a bond, a >CB2 group, a >NR group or a sulphur or oxygen atom.ALSO:The Specification describes the production of compounds of formula:-  <FORM:0904415/IV (b)/1> where R is a substituted or unsubstituted aryl group, A is an alkyl group, and B is hydrogen or an alkyl group not more than two Bs standing for alkyl groups.  A may be methyl, ethyl, n-propyl, iso-propyl, sec-butyl, n-heptyl or n-octyl.  R may be phenyl, a - or b -naphthyl or o-, m- or p-tolyl, 2:4- or 2:6 xylyl, o-, m- or p-chlorophenyl, p-methoxy- or ethoxyphenyl.  These may be prepared by catalytic hydrogenation (Raney nickel) of the corresponding dihydropyridine compound. Alternatively, in one example, sodamide, bromobenzene and 2-methyl-5-ethylpiperidine are reacted to produce N-phenyl-2-methyl-5-ethylpiperidine.  The dihydropyridine compounds may be prepared by reacting an amine such as p-phenetidene, p-toluidine or b -naphthylamine in the presence of water and acetic acid with butyraldehyde to form N-p-ethoxyphenyl-, N-p-tolyl-, and N-21-naphthyl-2-propyl- 3:5-diethyl-dihydropyridine respectively. Large quantities of 2-ethylhexenal are formed at the same time.  If desired the aryl groups from two molecules of the alkyl substituted heterocyclic compound may be linked through a methylene group by reacting, for example, N-phenyl-2-propyl-3:5-diethyl piperidine with formaldehyde in the presence of water, sulphuric and sulphanilic acids.  The product is a mixture of 2:21-,2:41 and 4:41-bis-(211 -propyl-311:511-diethylpiperidyl) diphenylmethane.

Abstract: 1395262 Electro-chemical analysis GREAT LAKES INSTRUMENTS Inc 1 Sept 1972 40695/72 Heading G1N In a device for measuring ion or molecular concentration or electrode potential including a pair of identical measuring electrodes a common reference contact connected to a reference potential is provided. In Fig. 2 a first, thallium/mercury electrode 22 of unit 20 insulatingly mounted in end wall 25 and an identical material electrode 22 contained within a standard pH sensitive glass electrode 37 filled with phosphate to simulate a stable dissolved oxygen concentration are connected via leads 27 and 36 and amplifiers 55, 56 to respective inputs of a differential amplifer 65 the output of which is connected via meter 68 to earth. When the electrode units 20, 21 are dipped in the solution 87 whose OXYGEN content is to be determined a potential is created between electrode unit 20 and an earthed screw 48 which is a function of the dissolved oxygen content and a potential is created between electrode unit 21 and the screw 48 which is a function of the thallous hydroxide 34 and pH difference between the solution 34 and a buffer solution 46 surrounding the glass electrode 37, the electrical path being through porous plug 45 and the glass electrode. Since the two potentials are subtracted in amplifier 65 variations due to the grounding electrode are cancelled. The buffer solution 46 is adjusted so that the output at meter 68 gives the oxygen concentration compared to the set reference. The temperature dependence of the electrodes is cancelled by the circuit. Electrode unit 20 may be replaced by a pH sensing glass electrode and instead of screw 48 a platinum electrode is positioned in solution 87 and earthed, Fig. 3 (not shown). Alternatively, Fig. 4 (not shown) the common earth may be an electrode in the buffer solution of the standard electrode. The arrangement may be used to detect oxidation reduction potential or ions such as sulphide, nitrate, cyanide fluoride, copper, bromide, cadmium, iodide, lead, fluoroborate, chloride, calcium perchlorate.

Abstract: 1383710 Record changer spindle PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 Sept 1972 [11 Sept 1971] 41805/72 Heading G5R In a record changer spindle for large hole records, secondary supports act to lift the record stack, other than the lowermost record, during the change process and pivot during the change process following release of the last record to halt the process and allow switch off of the changer.  During record change thrust rod 2 moves member 6 upwardly a distance b against the action of spring 10 in sleeve 9 and ribs 14 formed on the member move into slots 13 formed on the sleeve. During the first part of this movement the resilient secondary supports 8 which are pivotally mounted on cantilever arms 7 of the member 6 are pivoted by spring 20 surrounding sleeve 9 so that projections 21 of the supports explore the centre hole wall of the lowermost record then enter the interstice between that record and the next lowermost. The supports then commence lift of the stack above the lowermost record and at the same time the U-shaped resilient primary supports 16 secured to member 15 are moved upwards over a distance a by thrust sleeve 3 whereby the inclined parts 17 of the supports engage the parts 18 of the casing and the supports are withdrawn to allow the lowermost record to drop. Return movement of the thrust rod 2 and thrust sleeve 3 restores the spindle to its initial condition. In the absence of a record on the spindle the secondary supports pivot when thrust rod 2 moves upwards until projections 22 on the supports enter the slots 13 in the sleeve thereby stopping the further upward movement of the thrust rod. This stopping of the rod allows the changer to be switched off.
