Title: Improvements in electric railway systems
IPC: B61L3/14
Filed: 1932-04-22
Abstract: 390,957. Master control of D.C. motors. LOUGHRIDGE, M. H., Oakwood Avenue, Bogota, New Jersey, U.S.A. April 22, 1932, No. 11643. [Class 38 (iii).] On an electric railway for transportation of freight, the motor trucks are identical and can be coupled to form a train, and are remotely controlled from the track. The motors on two adjacent trucks can be operated in series or separately, the circuit changes being made by a centrifugally controlled switch on the leading truck. An automatic block system ensures spacing of the trains. For a train to proceed it is necessary for the power conductor 13, Fig. 1, to be energized, and also the block conductor 22 of the section through which the train is to travel. This conductor is energized from the conductor 13 through a resistance 20, but is de-energized if the section in front is occupied by reason of the train in front earthing a continuation 21 of the block conductor 22. A three-truck train is shown in Fig. 3. A switch 45 is closed only on the leading truck A. Switches 60 when placed as shown connect the motors 69 on trucks A, B for series-parallel operation whilst leaving the motor on truck C for independent operation. Trolley 41 on truck A contacts with block conductor 22 and when energized causes relays 44 on each truck to be energized through train wire 48. At low speeds trolley 43 on truck A, which contacts with power conductor 13, energizes over contact 52 of a centrifugal switch the series coils S on trucks A, B, train wire 57 connecting these coils S in parallel. A series circuit from trolley 43 over contacts of relay 44 and through centrifugally operatedrheostat 65, and motor 69 on truck A, train wire 76 and motor on truck B to earth. At a higher-speed contact 52 operates to de-energize coils S and energize coils M on trucks A, B, train-wire 53 connecting these coils M in parallel. Thereupon the motors on trucks A, B operate independently, the circuit for each truck being trolley 43, contacts of relay 44, rheostat 65, and motor to earth. The motor on truck C is in a similar independent circuit all the time. A trolley 42 on each truck contacts with and earths block conductor 41 and so ensures a vacant section of track behind the train. In a modification, Fig. 2 (not shown), the trucks are adapted for running in either direction. Each truck is provided with a polarized relay which reverses the field of the motor relatively to its armature according to the polarity of the power conductor 13, and interchanges the connection of trolleys 42, 41 according to the direction of travel. In this modified system motors of adjacent trucks are connected in parallel at low speeds and in series at' high speeds. The trucks may be equipped with a braking system as described in Specification 365,039.

Title: Improvements in or relating to apparatus for folding blanks of cardboard or like material
IPC: B31B50/58
Filed: 1959-04-07
Abstract: 896,793. Bending cardboard. WELLPAPPENFABRIK G.m.b.H. April 7, 1959 [Sept. 13, 1958], No. 11677/59. Class 100(2) [Also in Group XVII] In an apparatus for folding blanks of cardboard or the like the blanks 13 are guided between endless conveyer belts 2 and resilient rotatably mounted counter surfaces pressing on the conveyer belts from above and adjustable to accommodate different widths of blank, for example rollers 19 mounted in carriers 5, 7, the outer portions a of the blanks being progressively folded over towards one another by endless belts 11 spaced from each other and guided in movement so that the planes thereof are progressively rotated through 180 degrees, and the bent portions of the blanks are pressed, by loading means before the blanks are discharged from the apparatus. The carriers 5, 7 and a further carrier, not shown, disposed between them are mounted above the conveyer belts 2 on horizontal spindles such as 15 along which they are adjustable. The blanks 13 are grooved before they are fed into the apparatus and the rollers 19 of the carriers 5, 7 bear upon the blanks adjacent to two of the grooves, a disc 9 carried on the outside of each carrier engaging in and deepening each groove. Angled members 10 are mounted on the carriers 5, 7 adjacent to the discs 9 and provide edges around which the blank parts a are bent. The upper runs of the belts 11 which initially lie in a horizontal plane are guided by rollers 17 and are progressively twisted through 180 degrees. As the rollers 17 on one side of the machine are staggered in relation to those on the other side one blank portion a is folded flat against the remainder of the blank before the other. When both portions a have been folded over a resilient roller presses down upon each fold before the blank is discharged from the conveyer belts 2. The rollers on the carrier disposed between the carriers 5, 7 press upon a central groove in the blank 13 and thereby help to keep the main part of the blank in a horizontal plane. The horizontal part of the carrier 5 is longer than that of the carrier 7 and that of the central carrier is longer than those of both the others.

Title: Improvements in or relating to automatic soldering devices
IPC: B23K3/06
Filed: 1926-05-11
Abstract: 252,168. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 15,1925, [Convention date]. Soldering. - In an automatic soldering machine, solder wire is periodically moved towards and away from the work. being heated while moving towards the work. Soldering of the leading in wires to the caps of electric incandescent lamps to be screwed into or fixed by bayonet slots in their holders may thus be effected. A number of screw cap lamps may be mounted in bushings 41 in a rotatable table 40 and the leading in wires soldered respectively at 37, Fig. 1 and 49, Fig. 4, at successive stations. For soldering at the point 37, solder wire 4 supplied from a drum 7 is clamped with its end projecting from a bush 31, by rolls 12, 13 mounted on a lever 8, which is oscillated about its pivot 10 by a rod 11. The roll 12 is carried by a plate 15 pivoted at 19 on the lever 8 and is pressed against the roll 13 by a spring 26 on a set screw 30. The rolls are normally locked in position by pawls 20, 21, of which the pawl 21 is carried by a plate 16 pivoted on the axis 18 of the roll 13 and normally pulled by a spring 27 against a stop 29. When the lever 8 is raised the solder wire is carried back therewith until the end 24 of the plate 16 engages stop 25, whereupon the plate 16 is oscillated to rotate the roll 13 and so, through gearing 23, 22, the roll 12, to feed the wire through the bush 31. The lever 8 then moves down to convey the solder to the work. A burner 5 movable on a pivot 32 is provided with a rod 33 which passes with play through stops 35, 36 on the lever 8. When the lever 8 moves down the stop 35 engages the rod and the flame is thus directed continuously on the same part of the solder, which is melted by the time it reaches the work. When the lever 8 is raised, the flame remains for a short period projected on the work so as to prevent too sudden cooling of the solder and the burner is then raised by the stop 36 along with the lever 8. The mechanism for feeding the solder to the soldering point 49, Fig. 4, is of similar construction, but the lever 46 carrying the rolls 43, 44 is pivoted at 45. Stops on the lever engage a rod projecting from a burner which is movable on a vertical pivot. The work in either case may be previously heated.

Abstract: 1,104,638. Bunghole bushes; tapping barrels &c. P. B. BUCKLEY. 7 Feb., 1967 [21 March, 1966], No. 12416/66. Heading B8T. A plastics bung for barrels &c. has a tapered tubular part 3 with an integral end wall 5 which has a central weak spot 8 formed by reducing the thickness of the wall. When a tubular plug or hollow tapping connector (6), Fig. 2 (not shown), is, e.g., screwed or pushed into the tubular part 3, it ruptures the end wall 5 starting at the central weakened portion 8, but the pieces of the wall are still attached to the tubular part and bend back to form a seal against the end of the plug &c. The weakening of the wall 5 may be achieved by making either or both surfaces spherically or conically or cylindrically concave, Figs. 3-10 (not shown), or by using two perpendicular grooves (14), Fig. 12 (not shown), across the wall 5. The rupturing may be aided by arranging for the plug &c. (6) to exert radial pressure on the tube 3 so that the end wall 5 is under stress when the plug &c. contacts it.
