Title: Mechanism for effecting angular displacement of the brushes in commutator dynamo electric machines
IPC: H02K27/18
Filed: 1924-10-02
Abstract: 222,877. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Francaise pour l'Exploitation des ProcÚdÚs Thomson- Houston). Oct. 3, 1923, [Convention date]. Alternating-current commutator machines; motors, controlling.-In a machine of the type having two sets of brushes which are angularly displaceable in opposite directions for varying the speed, the brush-carrying rings are caused to move in such a way that the pair of brushes for any phase never cover the same commutator segment simultaneously. In Fig. 2, S represents diagrammatically one phase of the secondary winding connected to the independently mounted brushes a, b. The sector e of the voltage between the brushes may be resolved into a component er which is in phase with the secondary voltage and determines the speed, and a component ec which determines the power factor. To increase the speed of the machine, the brushes are caused to approach each other at different velocities. The slower brush b is then reversed, and in the position shown in Fig. 5, the machine runs at synchronous speed. In this position the component er is zero, but there is still a phase-compensating component ec. An increase of speed above synchronism is effected by moving the brushes first together and then in the opposite direction until in the position shown in Fig. 10. Figs. 11 and 12 show a method of imparting movement to the brushes. The carrier rings c<1>, c<2> are rocked by means of a hand- or otherwise operated drum A of cylindrical or paraboloid shape having appropriately formed spiral grooves R on the surface. Motion is transmitted to the rings by means of slides B<1>, B<2> working on parallel guides G<1>, G<2> and having projections engaging with the grooves R on the drum and with radially-slotted lugs O<1>, O<2> on the rings; alternatively, the connection between the slides B<1> and the brush-rings may be made by links. The slides B<1>, B<2> and guide, G<1>, G<2> may be dispensed with and fixed projections on the rings C<1>, C<2> enter the grooves in the drum. For reversible machines, two grooves may be provided for each brush-ring, there being a separate drum for each ring.

Title: Stabilizing methyl methacrylate polymers
IPC: C08F20/14
Filed: 1965-06-02
Abstract: The divalent Zn, Ni and Pb salts of dicyclohexyldithiophosphinic acid are prepared by treating a mixture of sulphur, ammonium hydroxide, water and ethanol with dicyclohexyl phosphine, while bubbling in helium into the mixture. To the filtered solution of ammonium dicyclohexyldithiophosphinate there are added, respectively, ZnSO4.7H2O, Ni(NO3)2.6H2O and Pb(OOCCH3)2.3H2O to precipitate the corresponding Zn, Ni and Pb salts.  The Ni salts of di-n-butyldithiophosphinic acid and di-n-octyldithiophosphinic acid are similarly obtained using, respectively, di-n-butylphosphine and di-n-octyl phosphine instead of the dicyclohexyl phosphine.  The cupric, cadmium, manganese and stannous salts of dicyclohexyl dithiophosphinic acid and the zinc salts of di-n-octyl and di-t-octyl dithiophosphinic acids may be prepared similarly.ALSO:Methyl methacrylate polymers are stabilized against heat and light by incorporating into the polymer, or adding to the corresponding monomer(s) before polymerization, dicyclohexyl dithiophosphinic acid or a dithiophosphinate salt of the formula (RR1PSS)2Me where R and R1 are individually alkyl of 2-18 carbon atoms, cycloalkyl of 5 or 6 carbon atoms, phenyl, monocyclic aralkyl of 7-10 carbon atoms or cyano-ethyl, and Me is a divalent cation of Zn, Ni, Pb, Cd, Ca, Ba, Mg, Cu, Sn or Mn.  The methyl methacrylate may be copolymerized with monomers such as alkyl acrylates and methacrylates, cycloalkyl acrylates and methacrylates, acrylic and methacrylic acid, acrylamide, methacrylamide, t-butylmethacrylamide, styrene, and alkyl- and halostyrenes. The polymers may be cross-linked by treating with agents such as ethylene glycol or polyethylene glycol dimethacrylate and 1,1,1-trimethylolpropane trimethacrylate during the polymerization process.  Benzophenone-type ultra-violet absorbers may be used in conjunction with the phosphinate salts. Polymerization can be effected with catalysts such as benzoyl peroxide, t-butyl hydroperoxide, di-t-butyl peroxide, cumene hydroperoxide, lauroyl peroxide and azobis-isobutyronitrile. Dyes, pigments and fire retardant additives may also be present during polymerization.  The polymers, particularly the homopolymers, are suitable for casting into sheets.
