Title: Process of preparing water-soluble resins which are suitable as binding agents in coating compositions for the electrical deposition of coatings
IPC: C08G63/553
Filed: 1968-03-09
Abstract: Alkyd resins are prepared by (a) partially esterifying the reaction product of a natural or synthetic drying or semi-drying oil and an [alpha],#- ethylenically unsaturated dicarboxylic acid with a monocyhydric cyclic alcohol, (b) esterifying the product with an excess of polyhydric alcohol to give a hydroxyl containing product and (c) esterifying the product of (b) with a polybasic acid anhydride. In step (a) the partial esterification with monohydric cyclic alcohol may be done to give a product with n mols. of anhydride groups/mole of oil and (b) with n mols. of polyhydric cyclic (n=1, 2, 3) alcohol. The step (b) may be conducted using a partial ester of a polyhydric cyclic alcohol and the polybasic acid anhydride. The oil may be the reaction product of a drying oil fatty acid and a polyol and may be modified before, during or after reaction with the [alpha]#-unsaturated acid by copolymerization with an unsaturated monomer. The monohydric cyclic alcohol may be carbo or hetero-cyclic and may be the partial ester of a polyhydric cyclic alcohol and a fatty acid. The polyhydric alcohol may be the partial ester (containing 2 hydroxyl groups) of a polyhydric cyclic alcohol and a fatty acid. The product of the invention may be further esterified with monohydric alcohols or monoepoxides and may be rendered water-soluble by treatment with NH 3 or an amine. The examples use adducts of linseed oil with maleic acid, soyabean oil with maleic acid, linseed oil and castor oil copolymerized with styrene and maleic acid and pentaerythritol with linseed oil fatty acid and maleic acid tricyclodecane monomethanol, methyl cyclohexanol, cyclohexanol, t.-butyl cyclohexanol, benzyl alcohol tricyclodecane dimethanol halogenated bisphenol-A, cyclohexane - 1,2 - diol, p - xylene-[alpha],[alpha]1-diol, 1,4- cyclohexane dimethanol phthalic anhydride, maleic anhydride, succinic anhydride, trimellitic anhydride, respectively in the steps (a), (b) and (c). In Example 15 linseed oil, dehydrated castor oil and styrene are copolymerized and then treated with maleic anhydride and esterified. In an example an eleotrolytically depositable paint is made by adding iron oxide to an aqueous solution of a neutralized resin.

Title: Time centering apparatus for railroad installations and other uses
IPC: G04C13/02
Filed: 1971-08-13
Abstract: A time centralizing apparatus, such as used in railroad installations, includes a line section having a plurality of stations each having a repeated panel. A pilot generator at one end of the line section transmits synchronizing electric pulses to the station nearest thereto, with the repeater panel of each station being adapted to synchronize clocks or other local servo devices and to transmit, to the next succeeding station, the sequence of pulses received thereby. A second or auxiliary generator at the opposite end of the line section is operable, responsive to non-arrival of pulses from the pilot generator, to transmit synchronizing electric pulses in the opposite direction along the line station to synchronize the cutoff stations. A respective reversing relay at each repeater panel normally conditions the associated panel to receipt of pulses from the pilot generator, and respective means at each repeater panel is operable, responsive to non-arrival of pulses from the pilot generator, to operate the reversing relay to condition the associated repeater panel to receipt of pulses from the second or auxiliary generator. A first time-responsive micro-relay at each station is maintained energized by a condenser which is charged by pulses received from the pilot generator. A second time-responsive micro-relay is provided and maintained energized by a condenser which is charged by pulses received from the second or auxiliary generator, and thus is normally deenergized. Upon non-arrival of pulses from the pilot generator, the condensor of the first relay looses its charge and the relay is deenergized to close an energizing circuit for the operating coil of the reversing relay, this energizing circuit being closed through a contact of the second relay. The reversing relay is thus operated. Upon restoration of pulses from the pilot generator, the auxiliary generator causes to transmit pulses. This results in discharge of the condensor associated with the second micro-relay, so that this second micro-relay is deenergized and opens the energizing circuit for the reversing relay. The latter thus is restored to a "normal" position in which it cuts off receipt of pulses from the second or auxiliary generator, and the first relay is energized, by charging of its condenser by pulses from the pilot generator, to open its contact included in the energizing circuit for the operating winding or coil of the reversing relay. A feature of the invention is that each station has its own local source of potential which is preferably supplied from a battery charged through a rectifier from the usual lighting circuit.
