Title: New bis-phenol compounds and their preparation
IPC: C07C37/18
Filed: 1958-05-28
Abstract: An epoxy resin is prepared by reacting x,x1-dimethylxylylene-bis-phenol (where x,x1-indicates that the compound is an isomeric mixture) with epichlorohydrin in acetone, adding aqueous sodium hydroxide during the reaction.  (Example 8). A rubber composition contains as anti-oxidant a compound of the formula <FORM:0885005/IV (a)/1> where R, R1, and R2 represent hydrogen or halogen atoms or alkyl, benzyl or alkylbenzyl groups.  The preferred antioxidants contain a substituent in each ring para to the hydroxy group.  An example describes ageing of vulcanized rubber test pieces from compositions based on pale crepe rubber bisphenols of the above formula.ALSO:The invention comprises bis-phenols of the general formula <FORM:0885005/IV (b)/1> where R, R1 and R2 represent hydrogen or halogen atoms, or an alkyl, benzyl or ring alkylated benzyl group and a process for their preparation by reacting a bis-chloromethyl xylene with a phenol of the general formula <FORM:0885005/IV (b)/2> The bis-chloromethyl xylene used is generally a mixture of isomers and the preferred phenols are those where the R groups are hydrogen, chlorine, an alkyl group of less than 5 carbon atoms, a benzyl group or a benzyl group bearing alkyl groups of less than 5 carbon atoms on the ring, the total number of carbon atoms in such ring substituents being less than 12.  The reaction preferably takes place at 100 degrees to 125 degrees using a mole ratio of bis chloromethyl xylene to phenol of 1 : 2 to 1 : 20 for 3-5 hours.  A dehydrohalogenation catalyst, e.g. zinc chloride may be used and if a product of improved colour is desired a solvent such as benzene or heptane may be used. The bis phenol, which is generally an isomeric mixture, may be recovered as a residue by distilling off the excess phenol and solvent, if any.  The compounds are useful as antioxidants for rubber, as germicides, particularly the chlorinated derivatives, and as intermediates for epoxy resins.  In the examples bis-chloromethyl xylene is reacted with monodimethylbenzyl - cresol, 2, 4 - dimethyl phenol, mono - isopropylbenzyl - m - ethyl - phenol, o-sec-butyl-phenol, o-sec-butyl-sec-butylbenzylphenol, p - chlorophenol, 2, 5 - dichlorophenol, phenol, bis-dimethylbenzyl-phenol and methylbenzyl-ethylbenzyl-phenol. Certain of the bis phenol products are analysed by acetylation.

Abstract: 1,056,484. Commutating poles. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. April 24, 1964, No. 17074/64. Heading H2A. [Also in Divisions G1 and G3] The compole excitation of a dynamo-electric machine is automatically varied to improve commutation and avoid sparking under changing load conditions. Photo-cell 4 detects the amount of sparking occurring at the edge of a brush and controls regulator 7, via amplifiers 5, 6, to buck or boost the compole flux either by altering the main current flowing in the winding or by varying the current in a regulating winding on the compole. To ensure that the control operates to minimize sparking a rate sensing device 9 is used to reverse the output of control amplifier 6. A further control proportional to load current determined by unit 7 is also included. If the machine is reversible detectors are used at both edges of the brush and their outputs compared so the rate unit may be eliminated. The photo-cells may be replaced by Hall plates or induction coils for detecting electromagnetic oscillations near the brush, or the harmonic content of the main field current may be used to operate regulator 7.

Title: Setting device for a timer
IPC: G04C23/40
Filed: 1973-04-11
Abstract: 1394013 Time switches SEIKO KOKI KK 11 April 1973 [21 April 1972] 17349/73 Heading H1N A setting device for a timer which is automatically reset at a predetermined time interval after release comprises means 1 mounted for movement between a first position and a second position; means 12 urging it towards the first position; means 3 for operating a switch 10 on movement of the means 1 between said positions; locking means 13 for holding means 1 in the second position; timer-operated release means 17 for automatically releasing means 1 from means 17 at a predetermined set time; and a return mechanism comprising a wheel member 21 with return means 24 thereon, an arm 5 on means 1 for co-operation with means 24, and drive means 25 timer-driven for rotating the wheel 21 at a given velocity so that means 24 acts on arm 5 to move the means 1 from the first position to the second position. As shown the wheel 21 is a gear-wheel having a toothless portion 23 such that timer-driven pinion 25 is not engaged until the slider 1 is released, whereupon arm 5 urges wheel 21 and pinion 25 into mesh and drive ensues until slider 1 has been restored to the position shown. The latch 13 may also be released manually by depressing its arm 19. The slider 1 may be restored at any time by manual pressure on button 9, but if the microswitch 10 is then again closed by manual release of slider 1 before wheel 21 has returned to its unmeshed position the time interval to automatic restoration will depend upon the specific angular position of wheel 21. This variation in time interval is avoided by a modification (Fig. 2, not shown) in which the gearwheel has no toothless portion but is carried on a pivoted bracket and is spring-urged out of engagement with the drive pinion until arm 5 moves it into mesh. Manual restoration by pressure on button 9 thus always results in disengagement of the drive and the wheel is immediately restored to its start position. Alternatively the arm 5 may be pivoted on slider 1 but normally restrained to be effectively rigid by a subsidiary latch (193, Figs. 5 and 5a, not shown); latch (193) co-operates with the movements of slider 1 to release arm 5 and prevent interference by pin 24 when manual release is desired with wheel 21 still in mesh with pinion 25. In a further embodiment (Fig. 4, not shown) the latch 13 is replaced by a timeroperated detent (133) of the kind disclosed in Specification 1,393,109. In yet a further modification (Fig. 3, not shown) the arm 5 is replaced by a pivoted link with a slot therein engaged over the pin 24.
