Electrical windings having organic and/or inorganic insulation are preheated to a temperature of between 180‹ and 280‹ F. and then treated, as by dipping, with a " rapidly curable varnish " (i.e. a composition comprising volatile solvents and resinous solids of such a nature that when a thin film 0.001 to 0.01 inches in thickness is applied to a surface the solvent evaporates and the resin sets to a hard tack-free coating in one-half hour or less at 300‹ F. in air) which is maintained at a temperature between 160‹ and 240‹ F., and the treated windings are then baked to evaporate the solvent and cure the applied varnish. The varnish may be an oxygen-convertible composition, e.g. it may contain as the major resin-forming constituent, drying and semidrying oils such as linseed, tung, and dehydrated castor oils, together with a volatile solvent such as toluene, benzene, naphtha, alcohol or combinations thereof; the oils may be combined with thermosetting or thermoplastic resins, gums, asphalts, and natural resins, and a drier such as lead naphthenate or manganese linoleate may be added. The varnish may also be an internally heat polymerizable synthetic plastic varnish, e.g. a composition comprising partially reacted phenol-formaldehyde resin, alkyd resins such as glycerol phthalate, pentaerythritol-maleates and drying-oil-modified glycerol phthalates, or melamine-aldehyde resin, or combinations thereof together with natural resins, pigments and plasticizers. Thermosettable oxidizing varnishes may also be used and include a small proportion of thermoplastic materials such as polyvinyl chloride, ethyl cellulose or cellulose acetate: they are prepared with alkyd resin such as glycerol-phthalate and linseed-oilmodified pentacrythritol-phthalate resins to which may be added phenol or urea-formaldehyde resin, plasticizers, e.g. diamyl phthalate, dibutyl sebacate, or tricresyl phosphate, pigments, driers and fillers. In the application of the apparatus shown electrical windings 18 are mounted on supports 14 rolling on a track 12 and conveyed thereby into an oven 20 where they are preheated as by means of infra-red lamps 22, and are then passed to a dipping position above a tank 24 to which thermosetting varnish is supplied from a reservoir 28 via a pipe 26 and heating unit 32. The tank 24 is hydraulically raised to immerse the windings and then lowered slowly to assist draining of excess varnish which latter operation is completed with the windings moved to a position over a drain pan 40. Finally, the windings are conveyed to a baking oven 42 wherein the applied varnish is cured.

Patent GB-254830-A (GB)
Abstract: 254,830. Siemens &. Halske Akt.-Ges., and Mathias, M. May 2, 1925. Automatic exchange systems ; metering.-In a zone metering system, the zone of the wanted subscriber is determined by the first two dialled digits, and these control auxiliary switches connected in tandem at the first group selector at the originating exchange to assess the charge for the call, which is also dependent on the duration of the conversation. The group selector IGW is reached over line switches 1VW, IIVW. The magnets, D1. D2 of the auxiliary switches MSI, MSII are controlled over back contact 12 of the line relay A1, and change-over is effected in the usual manner by means of a series of relays U1 U2 and off-normal contacts 14, 18. A wiper of the time switch Z<e> is thus selected. The impulse trains after the second do not affect these switches. When the called subscriber replies, answering relay B1 operates and connects up relay V3, which locks and closes a circuit for the magnet D3 of the time switch Ze over a periodically closed contact 44uk. The terminals of this switch are connected to terminals of an assessing switch AbS to determine the charge to be made. When the calling subscriber hangs up, relay C1 falls back and connect up the magnet D4 of the assessing switch AbS, which interacts! with the meter repeating relay ZR. Relay ZR closes a holding circuit for release relay V1, and at each operation sends an energizing impulse to the meter Z by short-circuiting a resistance 52. This action continues until the marked terminal of the assessing switch AbS is reached, whereupon relay F energizes and cuts the drive. Relays. ZR, V1, V3 then relapse, and magnets D1, D2, D3, D4 operate in turn over self-interrupting contacts to restore the corresponding switches under control of offnormal contacts. The two switches MSI, MSII may be replaced by a two-co-ordinate switch or by two groups of relays.

Abstract: 514,769. Coin-actuated apparatus WESTING- HOUSE BRAKE & SIGNAL CO.,' Ltd., ROBINSON. M. H., and BURNETT, W. E. April 12, 1938. No. 25487/39 Divided out of 513,785 [Class 27] Coin action, mechanical connection and multiple coin.-In a coin-actuated mechanism in which the coins actuate a counting-device or a mechanism for delivering an article of predetermined value, such as a railway ticket, the coin during its passage through the mechanism effects the movement of a lever to an extent which is independent of small variations in the diameter of the coin, from a normal diameter, the lever effecting the actuation of the counting or ticket issuing apparatus. Coins 26, 27 conveyed along a shoot 22 rock a lever 23 connected through a buffer spring 40 to a lever 28 the movement of which is limited by stops 29, 30. As shown, a large diameter coin 26, e.g., a penny, rocks the lever 23 twice by engaging projections 24, 25 thereon, while a halfpenny' 27 engages the projection 25 only, and rocks the lever once. Any small variation in the sizes of the coins is taken up by the buffer spring and does not affect the stroke of the lever 28, which is connected by a link 32 to a ratchet lever 34 carrying a pawl 37 for driving a ratchet wheel 36. The wheel 36 is rotated through two teeth by a penny 26 and one tooth by a halfpenny 27. It is rigid with a camwheel 44 having' projections 45 on its periphery, which after the passage of a predetermined number of coins, e.g., three pennies or six halfpennies, actuate a lever arm 49 connected to a link 50 leading to a mechanically-operated ticket-issuing mechanism. Alternatively, or in addition, the lever 49 may actuate an electric contact device 52 controlling an electrically actuated indicating device or a ticket issuing machine. The mechanism described may be used in combination with the coin-separating and conveying mechanism described in Specification 513,785.
