Title: Improvements relating to electric welding
IPC: B23K9/067
Filed: 1920-01-14
Abstract: 166,914. Longbottom, B., and Greenhalgh, E. Jan. 14, 1920. Heating by electricity.-A welding electrode is connected first to a circuit of comparatively high voltage and low current capacity for striking the arc and then either by hand or preferaby by an automatic switch to a second circuit of lower voltage supplying the welding current. Fig. 1 shows an arrangement of the circuits in which the change is effected automatically. The high and low voltage mains V<1> V<3>, V<2> V<3> may be supplied by a transformer T having two secondaries t<2>, t<3>, or by continuous current generators S, W. The work piece P is connected to the main V<3>, the welding electrode E being connected to the conductor 2 which is normally connected to the main V' to enable an arc to be struck when the electrode E and work P are brought into contact. This circuit is made through a solenoid a' and conductors 3, 4, 5, and a two-way switch A. The contacts a<2> of the switch A are normallv closed as shown on the left-hand' side of Fig. 1, but when the arc is struck the current in the solenoid a<3> raises the switch armature to close the circuit through the contacts a<5> and thus connect the electrode E to the main V<2> as shown on the righthand side of Fig 1. Instead of the two-way switch A, two separate contactor switches actuated by solenoids may be used, or foot or manually-operated switches may be employed. Fig. 3 shows an arrangement in which the current is automatically broken if a short-circuit occurs in the welding circuit. The electrode E and work P are connected to the high voltage mains V<1>, V<3>, and when the arc is struck the solenoid c<2> is energized, thus closing the switch I and energising the solenoid g<2>, and closing the switch G and opening the switch D<1>. The electrode E and work P are then connected to the low voltage mains V<3>, V<4>, the opening of the switch D' deenergizing the solenoid h<2> and opening the switch H. If the current in the welding circuit becomes excessive the overload solenoid k<3> opens the switch K and de-energizes the solenoid g<2> whereupon the switch G opens, switch D' closes, but the switch H remains open. The switch K remains open until the short-circuit is removed by d'isconnecting the electrode E from the work.

Filed: 1974-01-14
Abstract: 1462841 Exhaust silencers TENNECO Inc 14 Jan 1974 [14 March 1973] 01702/74 Heading F1B An engine or other source of acoustic pulsations is combined with a gas flow system and is such that when being operated to produce maximum noise, it produces a sound pressure pulse providing points of maximum and minimum compliance  spaced along the length of the gas flow path through the gas flow system, which system includes a pulse converter device for attenuating noise in the pulses of gas and comprises first and second volumes 53, 55, Fig. 4, forming first and second acoustic compliance sections and an inertance member 61, the volumes being larger in cross-sectional area than the mean cross-sectional area of the gas flow path and the inertance member providing a reduced cross-sectional area compared with said volumes. The compliance sections serve to oppose changes in pulse pressure during gas flow and the inertance member serves to oppose the changes in rate of gas flow. The compliance sections and inertance member may be contained in a common shell, Fig. 6 (not shown), or may have double end-walls for additional strength, Fig. 8 (not shown). In the embodiment shown in Fig. 9, the compliances are provided by first and second chambers 423, 427 and the inertance by third chamber 441 containing gas flow tube 457, the first and second chambers communicating with the third via gas flow passages 435 and 443 respectively. In Fig. 10, the first and second chambers 551, 553 are connected to the third chamber formed by small chambers 555 and 557 by way of gas flow passages 531, 539 and openings 535, 543. The gas flow system may have a conventional silencer 111, Fig. 5, upstream of the pulse converter to attenuate the highest frequencies and another 131 downstream which mainly acts to attenuate low frequencies, the medium and high frequencies having been attenuated already. The compliances formed by the first and second volumes, e.g. 53, 55, Fig. 4, should be located at points which would be of low compliance in a system consisting of a uniform pipe of predetermined length and the inertance e.g. 61 in Fig. 4, should be located at a point which would be of high compliance in such a system.

Title: Process for effecting hydrocarbon conversion reactions
IPC: C07C2/60
Filed: 1942-02-13
Abstract: Hydrocarbons are alkylated by passing a stream of a carrying fluid through a first contact zone containing a bulk supply of a Friedel-Crafts type catalyst, e.g. AlCl3, so that a portion of the catalyst is removed from the first zone under conditions precluding substantial chemical reaction between the fluid and the catalyst, maintaining a higher catalyst concentration in the first zone than in the effluent therefrom, passing the effluent to a second contact zone and therein reacting a saturated hydrocarbon with an olefin in presence of a Friedel-Crafts type catalyst, and maintaining a continuous flow sufficient to maintain the alkylation.  The hydrocarbon itself or part thereof may be used as carrying fluid and the olefin and an alkylation promotor such as HCl may be added between the first and second zones.  If desired, isomerisation of the hydrocarbon may take place in the first zone.  Packing material may be used, particularly in the second zone.  Examples are given of the alkylation of isobutane with ethylene and isobutene, and of the isomerisation of butane to isobutane followed by alkylation with ethylene.  Specification 564,697 is referred to.

Abstract: 659,415. Toothed gearing. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 24, 1949, No. 1930. [Class 80(i)] Toothed gearing giving a cyclically varying speed comprises a combination of a Geneva mechanism and an epicyclic gear. A driving shaft 2 carries a sun gear 10 of the epicyclic train, the annulus 13 of which is connected to a driven shaft driving a cam-switch device 14, and also drives the pin wheel 6, 7 of a Geneva mechanism through gears 3, 4, 5. The slotted wheel 9 of the Geneva mechanism is secured to a hollow shaft 8 which has arms 12 forming the carrier of the planets 11 of the epicyclic train. Thus, whilst the wheel 9 of the Geneva mechanism is stationary the planet carrier 12 is also stationary and the shaft 2 drives at a certain ratio through the sun 10 and planets 11 on to the annulus 13. During the periods in which the pin 6 of the Geneva mechanism drives the wheel 9 the carrier 12 of the epicyclic gear is also driven which results in an increased speed of the driven annulus 13. The epicyclic train may comprise friction gears instead of tooth gears.
