The auxiliary spring, the end portions of which, in all the constructions shown, extend in opposite directions, may be formed by an integral extension or extensions of one or more of the leaves of the main spring. As shown in Fig. 1, the auxiliary spring comprising a strip-metal plate 10, abuts the vehicle chassis at its curved upper end and at its lower end is riveted to the main spring 14, and is further secured by a U-shaped clip 17 fixed to the main spring. In modifications the lower end of the auxiliary spring may be formed channel-shape or with forked apertured ends to engage the main spring. Alternatively, the auxiliary spring may be secured to the chassis and bear on the upper face of the main spring. In another form, the auxiliary spring consists of an extension or extensions of one or more of the main spring leaves. When formed integral with the top spring leaf 14, as shown in Fig. 8, the auxiliary spring is formed with a securing eye 29 and engages a wear-plate 31 on the chassis. In other constructions the wear-plate is formed on the auxiliary spring by bending the latter back on itself or by securing a separate resilient plate thereon. Fig. 11, shows a laminated spring arranged transversely of the vehicle and formed with an extension 12 adapted to engage a wear-plate 35 mounted on the axle 36 or an abutment associated with the adjacent wheel. The auxiliary spring may be adapted to engage the main spring only when the latter is subjected to additional deflection. The invention is also shown applied to a two-wheel trailer such as is used for conveying aeroplanes, and having considerable length and, when loaded, a high centre of gravity. It is stated that the invention may also be used with three-quarter elliptic springs. The various details shown and described are applicable generally to the different constructions.

Abstract: 1388252 Feeding webs HUNTER ENG CO Inc 5 Feb 1973 [18 Feb 1972] 5505/73 Heading B8R  In a method of and apparatus for continuously feeding a web, e.g. aluminium or steel strip, through a processing section 12, e.g. a roller leveller, stretcher leveller or temper rolling device, which would mar the web if feed were stopped, a first and a second accumulator are provided one uptsream and one downstream of the processing section and means are provided for stopping the web and performing a servicing operation thereon, at one or other ends of the apparatus whilst maintaining a relatively slow web feed through the processing section. As described, the servicing operation consists of splicing a new web from a braked coil 14 to an expiring web at a joining station 17 and subsequently cropping off the join at a station 82 and winding the new web on to a new driven coil replacing a full coil 86. The web is fed through the apparatus by driven rollers which are capable of decelerating the web to a "creep speed" through the processing section 12 and a delivery section 13 whilst stopping the web in an entry section 11, a clamp preventing further web movement whilst splicing is effected. During this time web held in the upstream accumulator 26 is fed through the processing section. The clamp is released after the stopped web has been tensioned and the join is transferred to station 82 at an intermediate speed whilst accumulator 26 is re-filled with web. The web is then decelerated again and stopped and clamped in the delivery section 13 for cropping and replacement of the full coil 86, web from the processing section 12 being accumulated in the downstream accumulator 60. Finally, the web is tensioned, released and accelerated up to normal speed and the web accumulator 60 is emptied. In an alternative embodiment the web is stopped simultaneously in the entry and delivery sections, web being fed from the accumulator 26, to the accumulator 60 at a slow feed rate during this time. The processing section may include edge trimmers, cleaning and drying devices and tensioning devices. The accumulators may be hydraulically operated. Tensioning devices (44), (46), (48) and (52), (54), (56), Figs. 1A, 1B (not shown), maintain constant web tension through the processing section.

Abstract: 444,225. Retort furnaces. KRUPP AKT.-GES., F., Essen, Germany. Feb. 21, 1935, No. 5586. Convention date, March 3, 1934. [Classes 51 (i), 51 (ii), and 55 (i)] In apparatus for low-temperature carbonization, roasting, drying, or the like, of the kind comprising vertical retorts heated externally by a stream of continuously recirculated hot gases, the retorts are arranged in groups and means are provided for charging and discharging the retorts of each group as a unit. In the form shown in Fig. 2, two groups of four retorts 3 are arranged in each of two side by side channels 1, 2, the latter being connected at their ends by conduits 4 into which burners 6 .. 9 deliver and in one of which a circulating fan 11, driven by a motor 10, is disposed. The direction of gas circulation is periodically reversed by reversing the fan 11 and, according to the direction of flow, only one pair of burners 6, 8, or 7, 9, is in operation at the same time. Outlets are provided in the conduits 4 for the escape of a quantity of waste gases corresponding to that of the fresh hot gases supplied by the burners. To permit simultaneous charging and discharging of all the retorts 3 of a group, each of the latter is fitted with single lower and upper closure members similar to those shown at 31, 32, Fig. 3. In this modification, the retorts 27 are arranged in two groups of eleven each and the heating gas channels 21, 22 are superposed so that the upper and lower halves of the retorts are heated by oppositely moving gas streams. Fig. 5 shows a further construction in which a group of three retorts 37 is disposed in each of three side by side gas channels 36, the latter being connected by conduits 39 at the centre of which, opposite the middle channel 36, are provided the waste gas outlets 44, 45. In this form, the fan is omitted, the circulation being effected by the kinetic energy of the hot gases supplied from pressure-fired combustion chambers 40 .. 43. The waste gases escaping at 44 or 45 according to the direction of flow, are utilized to drive a turbine 46 which operates compressors 48, 49 for the air and gas supplied to the combustion chambers. Further recovery of heat is effected in an air preheater 47 traversed by the gases leaving the turbine 46. Specification 362,522 is referred to.
