Title: Improvement in chlorinated rubber adhesives
IPC: C09J179/02
Filed: 1945-10-22
Abstract: An adhesive composition comprises chlorinated rubber-like material to which is added a polyalkylene polyamine of the formula NH2-(CR2-CR2-NH)n-CR2-CR2 -NH2 in which R independently in each occurrence may be hydrogen or a methyl, ethyl, or propyl group, and n is an integer from 1 to 4.  The basic material may be a chlorinated polymerized chloroprene or butadiene, or copolymerized butadiene and styrene, butadiene and acrylonitrile, or the like.  The polyamine is preferably one in which n is 3 or 4, and R is mainly hydrogen, e.g. tetraethylene pentamine or pentaethylene hexamine.  Up to 3 per cent of the polyamine may be added.  The chlorinated substance is preferably dissolved in an aromatic solvent, e.g. toluene, benzene, or the like, but methyl ethyl ketone or methyl, ethyl, propyl, or butyl acetate, propionate, butyrate, or lactate may be used. Preferably, the polyamine is added to the base material a relatively short time before use, or if desired, the surfaces to be adhered may be coated first with the base and subsequently subjected to the action of the polyamine. Specification 600,989 is referred to.  The adhesive can be used for bonding natural or artificial rubber to metals, plastics, textiles, paper, fibre board, or other rubber-like material, particularly where solvent-resistant properties are required.ALSO:An adhesive composition comprises chlorinated rubber or like material to which is added a polyalkylene polyamine of the formula NH2 - (CR2 - CR2 - NH)n -CR2 - CR2 - NH2 in which R independently in each occurrence may be hydrogen or a methyl, ethyl or propyl group, and n is an integer from 1 to 4.

Filed: 1920-10-01
Abstract: 155,807. Cutter Electrical & Manufacturing Co., (Assignees of Scott, W. M.). Dec. 24, 1919, [Convention date]. Automatic circuit-breakers.-A circuit-breaker comprises two switch arms, one in each pole of the circuit, independently operable by opposite argular movements of a common operating lever, retained set by an overset toggle-linkage and tripped, independently, by an overload tripping device associated with each switch arm or, together, by a longitudinal movement of the operating spindle. To close the circuit-breaker the handle 57 is rotated first in one direction until the plate 72 on the operating spindle engages the last link 32 of the toggle of one switch arm and presses it into the closed position shown, and then in the other direction to close the other switch arm. If an overload exists one or both of the adjustable pivoted armatures 43 is attracted by its series solenoid 21 and knocks up a pin 47 (which is toothed at its ends to limit its movements) to upset the toggle. By pressing the knob 54, inwardly, the plate 72 engages projections 37 from the links 32 of the toggles and trips both switches. The cover is secured by a set-screw 6 passing into pillars 8 secured to the base, and, by passing a padlock through ears on the cover near the set-screws, unauthorized opening of the cover is prevented. The operating handle may be secured by a padlock to an ear 61 on the cover. The on or off condition of the switch can be seen through glazed open. ings in the cover.

Title: Starter circuits for discharge lamps
IPC: H05B41/04
Filed: 1968-06-12
Abstract: 1,182,028. Control systems for high pressure discharge lamps. NOVELECTRIC A.G. 12 June, 1968 [19 June, 1967], No. 28002/68. Heading H2H. A control system for a discharge lamp, such as a high pressure sodium or mercury vapour lamp, comprises means whereby the restarting of a hot lamp is enhanced. A discharge lamp 12 is connected to an A.C. supply OP by way of an inductor having a tapping 11, the lamp being shunted by a circuit connected to the tapping 11 and comprising a thyristor 18 and a condenser 16. The control electrode 20 of the thyristor is connected to a point in a circuit connected across the major part 10 of the inductor, the circuit including a resistor 22 and a contact 28 operated by a relay winding 26 which is energized by the minor part 13 of the inductor by way of a full-wave rectifier 24. When the system is initially switched on by a switch 14 the inductor carries little current, the relay winding 26 is thus not energized and the contact 28 remains open. A periodic signal is thus devised by way of the resistor 22 and applied to the control electrode 20 so making the thyristor conductive during alternate half-cycles of the supply OP. A pulsating current flows via the part 13 of the inductor to charge the capacitor 16. A high voltage is then induced across the whole inductor which causes the lamp 12 to ignite after one or, at the most, a few half-cycles of the supply. After the lamp has ignited the portion 13 of the inductor provides a voltage sufficient to energize the relay winding 26 to close the contact 28. The thyristor is thus rendered non-conductive during normal running of the lamp 12. Should the lamp be switched on when hot following a short interruption in the running thereof, the thyristor will continue to provide starting pulses for the lamp until it has cooled sufficiently to enable it to be re-ignited.

Negative or positive feed-back windings 49, 50 may also be provided. Further windings 51, 52 may provide an A.C. output. The rectifiers may be oppositely poled, as shown, to afford a full-wave rectified output, or poled in the same direction to render the polarity of the output dependent upon that of the control current. Fig. 3 shows a combination of these two arrangements using four reactors and giving a full-wave rectified output dependent as regards polarity upon the control current. The several control windings may be combined into a single winding embracing all the reactors-as also may the feed-back windings. Several control windings excited by different currents may be provided. If only an A.C. output is required, the terminals 47, 48 may be short-circuited. Alternatively, the A.C. output windings may be omitted and an inductive load supplied from the terminals 47, 48 through a condenser.
