The framework 3 of the loader is pivoted at 7, an adjusting device 8 being provided at the opposite side of the framework so that the latter can be pivotally moved to adjust the height of the bucket wheel 4 and the inclination of the scraper chain 5. The jib of the scraper chain 5 is pivoted to the framework 3 and is angularly adjustable by means of a cable 9. The bridge 10 is supported at both ends on rails 11, Fig. 2 (not shown), and the conveyer belt 12 delivers to either of a pair of removal conveyer belts 14. During operation, either the bridge is kept stationary while the loader is controlled to move parallel to the bridge or the loader is moved, for example non-linearly to maintain a constant feed, while the bridge is controlled to follow the lateral movements of the loader. One end of the bridge may be pivoted to the adjacent chassis. The bridge 10 may be further supported by a chassis 16 on an intermediate rail 17, Figs. 3 and 5 (not shown), in which case part of the bridge 10 is supported, e.g. by a roller, on the loading device and the advance of the rail 17 is effected by a mechanism on the loader which can be operated to lift the chassis 16 clear of the rail 17 and includes a pivoted bell-crank lever 18 for advancing the rail 17. The pile 2 may be annular with the bridge travelling on concentric rails or supported to pivot about one end, the other end being supported on a circular rail. The adjusting device 8 may be operated automatically. The belt 12 may travel over a support device provided on the loader to maintain a constant distance between the belt 12 and the delivery end of the belt 13. The height of the support device may be controlled in conjunction with the control of the adjusting device 8, and the supporting structure of the belt 13 may be pivotally mounted on the framework 3 for similar control.

Title: Improvements in automatic fire alarm plants or systems
IPC: G08B17/06
Filed: 1933-12-01
Abstract: 409,617. Fire-alarm systems. EKMAN, O. I. H., 64, Malmskillnadsgatan, Stockholm. Dec. 1, 1933, No. 33828. Convention date, Dec. 1, 1932. [Class 40 (i).] In a fire-alarm system of the kind comprising a number of double or multiple-wire loops connected in parallel to a battery and normally closed, each loop including at least one relay and thermal circuit breakers, the relay or relays are arranged between one end of the individual wires of a loop and one and the same pole of the battery, and resistances and other components introduced into the wires and the wires themselves are of similar resistance and disposition, so that all wires of a loop are, at similarly located points in the loop, equipotential. As shown, loops I, II arranged in parallel with a battery B comprise wires a, b in which are inserted relays RIa RIb, RIIa, RIIb each having a normally-closed contact. The relay contacts of all the a wires are in series-circuit with a relay ARa, and of the b wires with a relay ARb. The normally-open contacts of relays ARa, ARb are in series with each other and with the battery B and a fire-alarm box BS. If any a wire is broken, its corresponding relay and the relay ARa are actuated, contacts of the latter closing a fault-alarm circuit, not shown. If a b wire also is broken, as by fire fusing a circuitbreaker T, the circuit through the fire-alarm box BS is closed. Earth leakage in any loop wire is indicated by a relay JR and signal JL, relay JR being in circuit with an overload relay OR and having an earth connection J. Relay JR is normally energized, and is de-energized if any wire a or b is earthed. Relay OR is energized and actuates a signal OL if any wire a or b contacts with an outside conductor at high potential. Each relay in the system is associated with a fault indicator, not shown. Switches KSaI, KSbI, &c. are included in each wire. If a loop relay is not de-energized when the corresponding switch is opened, a shortcircuit between the wires of that loop is indicated. Preferably, the wires of a loop have their insulation coated with metal foil, which is earthed, so that a short-circuit causes earth leakage which is indicated by relay JR. In a modification, each loop is provided with a single relay having a separate winding for each wire. Common fault relays and alarm relays for the loops are provided. In another modification, the contacts of the several loop relays are connected in series-parallel with a common fault and alarm relay. The earth-leakage relay is arranged also to signal failure of the battery B.

Title: Improvements in means for loading and securing a trailer on a railway truck and for unloading same therefrom
IPC: B60P3/077
Filed: 1938-11-24
Abstract: 521,666. Carrying trailers on rail vehicles. SOC. D'ETUDES ET DE REALISATIONS MECANIQUES. Nov. 24, 1938, No. 34217. Convention date, Nov. 25,1937. [Class 78 (iv)] [Also in Group XXXII] A rail vehicle is fitted with means for carrying trailer road vehicles without impairing its efficiency for handling other kinds of traffic. Brackets 2, Fig. 1, are let into the vehicle floor so as not to project above its surface. Conical locating brackets 14, Fig. 6, with recessed portions 16, are fitted with eccentrically-mounted shanks 1a which can be passed through enlarged portions of the brackets 2 and then turned to fix the two brackets together. When the trailer has been positioned on the truck, the body is lowered so that members thereon pass down over a series of these conical surfaces thus holding the body in position. In addition, the conical surfaces may force pivoted arms 17, Fig. 10, on the body apart against the action of the springs, 20, thus causing these arms to snap into the recesses 16 and hold the body against vertical movement. The arms are separated forcibly by hand levers 21 when it is desired to remove the body. To get the trailer into position on the vehicle for engaging the surfaces 14, a pair of wheelengaging members as shown in Fig. 4 are engaged by similar shank members with other brackets 2. These members consist of two portions 9, 10 of which 10 carries attachment studs 11 fitting into keyhole slots on the member 9. In loading from a platform at the side of the rail truck, one member is turned to face the trailer wheels and the latter is backed laterally into engagement with it. As the backing continues, this member rotates on its shank and gradually slews the trailer round until it is parallel with the rail truck, and the other wheel engages the other member. It is then in position for lowering the body. Fig. 11 shows an alternative support for the body in which the conical members 26 are fitted with rollers running on parabolic tracks 28 fitted to the containers.
