Patent GB-133768-A (GB)
IPC: H01H21/50
Abstract: 133,768. Damey, R. K. Oct. 15, 1918. Switches, quick-action.-Relates to switches of the kind in which the switch lever and the operating-lever are mounted on a common pivot with the quick-action spring between them, and a spring bolt employed to lock the switch lever is released, for instance by a cam, when the spring has been adequately strained. According to the invention, the spring bolt, which is guided to reciprocate within the switch lever, is released by a link connecting it eccentrically with the handle. In the construction shown in Figs. 1 and 2, the handle 4 directly rotates the pivot 3 which is. mounted within a fixed quadrant 1 having locking-notches 18 at its ends. The contact lever 5, which carries a bridging-contact 9, is loose upon the pivot, which carries a spiral spring 6 the ends of which are bent over so as to be engaged by an inwardly bent crank 8 fixed on the pivot, and to engage on either side of a fixed projection 7 on the switch lever. The locking-bolt 17 slides in a slot in the switch lever, and is mounted on a rod 15 extending from the projection 7 and carrying a light spring 16 urging the bolt into one of the locking-slots 18. The bolt is operated to withdraw it from the slot by a link 19, Fig. 2, mounted on an eccentric pin on the pivot or on the handle, when the movement of the handle has adequately strained the spring 6 through the crank 8 to produce a rapid movement of the switch lever by the action of the other end of the spring on the projection 7 of the switch lever. Both positions of the switch lever may be contact positions, so that the switch may serve as a two-wav switch. The bolt may engage with slots in the fixed contacts, the slotted quadrant being dispensed with.

Title: Selective removal of nitrogen oxides from gas streams
IPC: C01B21/26
Filed: 1960-04-14
Abstract: Oxides of nitrogen are removed from oxygencontaining gases also containing nitric oxide, nitrogen dioxide, and inert gases by selectively reducing nitrogen dioxide to nitric oxide with hydrogen, carbon monoxide or a gaseous hydrocarbon fuel, present in an amount less than the oxygen equivalent, and then selectively reducing nitric oxide with ammonia, the reductions being effected in the presence of a platinum group metal catalyst, especially platinum, ruthenium or palladium.  The catalyst may be a single catalyst in a single bed or a plurality of beds, or it may be a plurality of catalysts, either in layers in a single bed or in a plurality of beds.  The upstream catalyst is preferably ruthenium and the downstream catalyst platinum.  The ammonia may be mixed with the gas either before or after the nitrogen dioxide-nitric oxide conversion.  Specifications 849,842, 883,944, 883,946 and 916,693 are referred to.

Title: Electric protective arrangements
IPC: H02H7/10
Filed: 1925-05-22
Abstract: .241,484. British Thomson-Houston Co., Ltd., (General Electric Co.). May 22, 1925. Cut-out arrangements for electric machines having windings through which current may be transmitted at a voltage and frequency changing in the same proportion (for example a frequency changer) are made sensitive to a dangerous drop in voltage notwithstanding the corresponding drop in frequency by including in the maintaining circuit of the main switch a resistor 11 of such value in relation to the impedance of the operating coil 9 of the switch as to permit opening of the switch when the voltage and frequency of the line have decreased to a predetermined value. In closing, the switch 5 completes at the interlock switch 12 the maintaining circuit through the resistor 11, and, in starting up the machine, the resistor is shortcircuited by the hand-operated switch 13.

Filed: 1918-08-19
Abstract: 118,630. Remy Electric Co., (Assignees of Conklin, O. F.). July 10, 1917, [Convention date]. Regulation, automatic systems and apparatus for.-Charging a battery B by a variable-speed generator G at an excessive rate is prevented by a thermal regulator which cuts resistance into the field circuit F, the bimetallic strips 9 forming the regulator being heated by a coil 16 carrying the charging-current; the current passes through the bimetallic strip, the coil 16 being connected to the free end of the strip. A voltage heating-coil 18 may be used in addition to the series coil. On a predetermined rise! of current or of generator speed, the strip separates the contacts 12, 14, inserting the resistance 28 in the field circuit; on a still further rise in current and further deflexion of the strip, an insulated block 30 on the strip lifts the blade 15 and inserts a second resistance 27. The strip may be placed near the generator or the commutator, and be affected by the heat thereof. The coils 16, 18 may be embedded in enamels. More than two resistances may be inserted in the field circuit. Specification 112,415 is referred to.

Title: Improvements in the production of nitric acid
IPC: C01B21/26
Filed: 1928-05-10
Abstract: 311.553. Smith, C. C., and Imperial Chemical Industries, Ltd. May 10, 1928. Nitric acid of about 70 per cent strength is obtained by absorbing oxides of nitrogen, obtained by oxidation of ammonia, in water or dilute acid from a previous operation, evaporating the acid to obtain a residue of concentrated acid and a distillate of dilute acid which is used in the absorption apparatus. The evaporation may be effected by the hot gases leaving the ammonia oxidation burner, before or after they have been used to preheat the gases entering the burner, the hot gases being passed through vertical tubes of a calandria apparatus, while the acid surrounds the tubes.

Title: A process for the production of low-shrinkage polyethylene terephthalate filaments without a ring rail period
IPC: D01F6/62
Filed: 1958-04-30
Abstract: <PICT:0835522/IV (a)/1> Polyethylene terephthalate mono- or multi-filaments are stretched by passing them around a stationary braking pin heated to 80-135 DEG  C., withdrawing them at high speed by means of a withdrawal member, passing them over a fixing pin heated to 180-210 DEG  C., passing them to a second withdrawal member with a speed 5-10% lower than that of the first withdrawal member, and then winding the filaments on a ring-twisting cap.  The initial stretching and fixing, followed by partial relaxation, thus achieved, results in the production of low-shrinkage (e.g. 2-3% on boiling) filaments without a "ring-rail period" (i.e. periodic fluctuations in elongation and shrinkage which cause periodic irregularities in dyeing).  As shown, the filaments, supplied at a speed of 50 metres/min., are wrapped once around the braking pin 1, and are withdrawn by the grooved withdrawal roller system 2, consisting of a first withdrawal roller 2a and a second withdrawal roller 2b of smaller diameter.  The filaments are wrapped several times around 2a, with the use of a guide roller 3, and withdrawn at 200 metres per min., so that the stretch ratio is 1:4.  The filaments then pass to a stationary fixing pin 4 heated to 190 DEG  C., and then to 2b, which has a peripheral speed 8% less than that of 2a, thus permitting partial relaxation of the filaments.  The filaments are wrapped around 2b, again by means of guide roller 3, and are then wound by means of a ring-rail on to a stretch-twisting cap 5.
