Title: Improvements in electric automatic circuit-breakers having arcinterruption chambers
Inventor: GROSS-BRAUCKMANN HELMUT
IPC: H01H73/18
Filed: 1960-12-02
Abstract: 900,526. Arc-rupturing in switches. LICENTIA - PATENT - VERWALTUNGS - G.m.b.H. Dec. 2, 1960, No. 41573/60. Class 38 (5). In automatic circuit-breakers having a centrally-arranged operating mechanism and electromagnetic release coil, with arc chambers adjacent these members, the chambers are longitudinally sub-divided by partitions to increase the distance available for arc-extinction. Figs. 1a, 1c show a socket switch comprising a compartment 4 which houses the operating mechanism, release coil and a thermal release member, and having sub-chambers 7 ... 10 formed by partitions 5, 6. Chambers 7, 9 have ventilation apertures 16, 17 and chambers 8, 10 contain fixed contacts 12, 13 and a pivoted contact bridge 14, 15. Additional arc space may be provided in the socket chamber by inserting a transverse plate under the ventilation apertures. The release coil may be arranged as a blow-out coil, or so that it has no effect on the arc. Figs. 2a, 2c show a screw-cap switch having a mechanism compartment 22, a chamber 24 for the release coil, sub-chambers 25 ... 28, ventilation apertures 36 and a contact arrangement similar to that of the socket switch. In a modification of the screw-cap switch, Fig. 3c, the partitions 40-43 are perpendicular to the mechanism compartment 48 and form six sub-chambers 44, 45, 50 ... 53, chambers 44, 45 being in communication with each other through the contact zone, Fig. 3b (not shown), and with chambers 50, 52 and 51, 53 across the tops of the partitions, Fig. 3a (not shown). Fixed contacts 47, 48 co-operate with a rectilinearly-movable contact bridge 49 and a thermal release member is provided. In another modification the switch of Figs. 2a, 2c has a row of quench plates arranged in the upper part of each inner sub-chamber and a blow-out coil in each outer sub-chamber, Figs. 4, 5, 6 (not shown). The plates at a corresponding end of each row are connected by a wire and each coil is connected between a fixed contact and its insulated arcing horn. In a further modification the switch of Figs. 2a, 2c has U-shaped quench plates with limbs of unequal length, the plates being arranged in adjacent sub-chambers and their communicating passage so that the longer limb lies in the outer chamber, Fig. 7 (not shown). The upper ends of the plates in the outer chambers have projections which decrease the plate spacings at these points, Fig. 8 (not shown). If desired, plates having an L-shape may be used.

As shown, the substrate is clamped on to a longitudinally gapped table 8 by two rows of spring-returned, pneumatically or hydraulically actuated rams 17 supported by parallel bridges 16 which are disposed one on each side of the table gap, are preferably cooled by coolant, e.g. water, flowing in jackets 25, and may be insulated from welding heat by shields 26, e.g. of asbestos.

Sheet handling means such as roller conveyers (10, Fig. 2, not shown), may be provided for moving the substrate to and from the table. Coolant is applied to the back of the substrate through a conduit 15 and a perforated spray pipe 14. Spent coolant is collected in a trough 12. As shown, the gap is provided with a seal 13, e.g. of rubber, for engagement with the substrate. To provide cooling control, a metal sheet may be placed between the substrate and table or, preferably, may roof the gap flush with the table. Consumable electrode wire from a reel 37 is fed, by a feeding device 42, to the weld zone via a guide tube 35 supported by a carrriage 30 movable on rails 28, parallel to the table gap. The carriage is self-driven by an electric motor 32 via a variable speed reducing gear 33. Carriage travel extent may be determined by limit switches. The guide tube is preferably transversely-horizontally and vertically adjustable, by rack-and-pinion and screw respectively, on a crosshead 38. The latter may be transversely reciprocated on carriage rails 39 by an electric motor 44 via a variable speed gear (45), crank 40 and connecting rod 41. The crank 40 is preferably of variable throw for variation of crosshead reciprocation amplitude. The carriage carries an A.C. or D.C. welder 34. The crosshead 36 may carry means for feeding powdered flux, powdered metal or shielding gas to the weld zone.

Filed: 1961-12-12
Abstract: In a process for the production of fire resistant polymethanes from an organic polyhydroxy compound and an organic polyisocyanate, up to 50% of the polyhydroxy compound may be replaced with a phosphoramidate of formula (RO)2P(=O)NH2 wherein R is an alkyl, alkenyl or substituted alkyl or alkenyl having from 1 to 10 carbon atoms or an aryl or substituted aryl group e.g. butyl, hexyl, nonyl, allyl, phenyl and totyl.  Phosphoramidates specified are: bis-(2-chloroethyl)-, bis-(2-bromoethyl)-, bis-(2, 3-dibromopropyl)-, bis-(chlorophenyl)- or bis-(bromophenyl)-phosphoramidates, and are preferably added in amount 15-25% of the mixture. Water may be added to produce a cellular product and foaming may be assisted by a fluorocarbon. The polyhydroxy compound may be a polyether, polyester or polyester amide of functionality at least 2 and molecular weight at least 400 e.g. polypropylene oxide of M.W. 1,000-4,000. Catalysts and cell-controlling agents may be added.  In examples diisocyanate was added to a mixture of polyether or polyester and phosphoramidate in the presence of silicone polymer, dibutyltin dilaurate, triethylene diamine, N-ethylmorpholine and water, and the foam cured at 100 DEG C. for 20 minutes.  In example 3 the polymer was a propylene oxide-glycerol condensate and the phosphoramidate was dinonyl phosphoramidate.  In a modification a foam which did not contract on curing was prepared by initially mixing the polyether and phosphor amidate at room temperature.  Specification 892,136 is referred to.

Abstract: 1365617 Feeding webs LANDIS & GYR GmbH 27 Sept 1972 [5 Oct 1971] 44624/72 Heading B8R Apparatus for automatic feed of layers of concertina-folded paper, e.g. in an automatic ticket machine comprises a drivable gripper roller 5 having a friction coating, a support 4 spaced therefrom to leave an opening 8 into which paper engaged by the gripper can move, a guide plate 9 and conveyer rollers 10. The apparatus avoids the necessity to join the leading end of a new stack to the trailing end of the previous stack or the hand feeding of the leading end into the conveyer rollers 10. In operation the leading end 7 of a stack 3 is withdrawn by the friction roller 5, forming a loop until the end leaves the roller 5, falling and, due to its elasticity, engaging the guide plate 9 until it enters the conveyer rollers 10. Figs. 2-4 (not shown). The rollers 10 are coupled to the roller 5 by a disengageable coupling to be driven at a higher peripheral speed. Sensing means 11, e.g. photo-electric detect the absence or presence of paper after the rollers 10 to connect or disconnect the drive to the roller 5 as appropriate.
