Title: Improvements in or relating to current converter installations employing semi-conductor rectifier elements
IPC: H02H7/12
Filed: 1960-03-30
Abstract: 914,127. Rectifying. SIEMENS-SCHUCKERTWERKE A.G. March 30, 1960 [April 10, 1959], No. 11264/60. Class 38 (2). Failure of a semi-conductor rectifier in an arrangement including a number of parallel rectifiers is indicated by a device operated by an element responsive to reverse current in series with each parallel arrangement. Rectifiers 9 are connected in series with fuse 21 and each parallel arrangement 5 is connected in series with a transformer 35 including a D.C. biasing winding 43 and an output winding 47 connected to indicating device 54. Transformer 35 is normally saturated and only becomes desaturated and delivers an output signal when a rectifier fails and reverse current flows. When the fuse has melted the rectifier system operates normally, but with two rectifiers carrying a current normally shared between three, until the faulty rectifier is replaced. Each saturable transformer 35 may have its own fault indicating device. The transformers may be replaced by magnetically polarized reverse current relays in parallel with resistors, or by non-polarized relays, each in series with a rectifier across a resistor.

Title: Improvements in and relating to filter presses
Inventor: TAYLOR ROCHESTER LEATHERLAND
IPC: B01D25/172
Filed: 1968-03-08
Abstract: 1,234,787. Filter presses with automatic mechanism for transfer of plates. PROGRESS ENGS. Ltd. 28 Feb., 1969 [8 March, 1968], No. 11313/68. Heading B1D. The plates of a filter press are transferred in either direction along the press by an automatic mechanism comprising a carriage 1 having rockers 4, 4' and levers 8, 8', the carriage being drawn along the press in either direction by flexible connector 2 controlled by an automatically reversing drive. The mechanism is controlled by a movable member 10, e.g. a peg which can be inserted into alternative holes in a mounting plate on the carriage. When the peg 10 is in a first position (Fig. 1) the mechanism can move the plates 11 to the left as follows: carriage 1 moves right, therefore rocker 4 rides up over first plate 11, this causes stop 5 to raise lever 8 which therefore releases stop 7', hence allowing rocker 4' to fall (Fig. 2, not shown). On rocker 4' striking plate 11, see Fig. 3, the reaction produced causes automatic means to reverse carriage 1, causing rocker 4 to carry plate 11 to the left; at the end of the trafectory rocker 4' rides up plate 11', thus causing it to be restored to its Fig. 1 configuration. The cycle is repeated till all the plates 11 have been transferred to the stack 11'. To achieve the opposite result (i.e. convey plates from stack 11' to 11) peg 10 is removed and replaced in a hole to the right of its position in Figs. 1 and 3 (illustrated in Fig. 4, not shown); rocker 4' now becomes the conveyor whereas rocker 4 becomes the trip cam. To allow carriage 1 to override the plates without moving them, peg 10 is moved to a further position (Fig. 5, not shown) to support levers 8, 8' in an elevated position wherein they engage stops 6, 6' to raise rockers 4, 4' to their inoperative position.

Filed: 1928-04-20
Abstract: 316,114. Terrey, A., Esson, J. J. C., and Bargate, R. A. April 20, 1928. Delivery apparatus.-Products of a printing-press, such as magazines and newspapers, are delivered by mechanism which deposits them on a horizontal strip of wrapping-material in batches of specified quantity, with the backs of successive batches facing in opposite directions, and after a predetermined number of batches have been collected, the wrapping-material is passed around the pile and fastened. The printed web z, Fig. 1, passes to the usual cutting and folding cylinders x, y and folding-rollers c, d, and the single products pass to one or other of two sets of inclined endless tapes a, a', according to the position of switches 10 operated from a cam n. Rotary beaters e, e<1> beat out the products from the tapes a, a' on to pairs of supporting slats f, f<1> on shafts g. When the number of products determined by the switches 10 has been deposited on one of the pairs of slats f, f<1>, that pair is rotated about its shaft g, by mechanism p, q actuated from the cam n, to lower the slats into a horizontal position, over vertical guides h slotted for the passage of a strip of wrapping- material, such as brown paper strengthened with webbing or tape. The slats are then moved apart horizontally, to drop the batch between the guides h to form a pile on the strip j by lever mechanism actuated from a cam rotated from one of the beater shafts 2, the slats being slidable on the shaft g. Meanwhile the next batch for the pile is being deposited on the other pair of slats. The strip is fed from a reel k by ratchet mechanism so that the pile descends as successive batches are deposited, with the strip j around three sides of the pile; an adjustable platform may be provided to prevent undue sagging of the strip j, and is moved clear to drop the completed package on to a conveyer w. The strip j is secured at the free end by pivoted hooks 20, Fig. 5, on a bracket m on one of the guides h, Fig. 1, and passes over a travelling roller u, which is traversed by a link v at the requisite time, to carry the strip over the top of the pile, and to bring the roller into co-operation with a stapling-mechanism 13 and a cutter 15 on the bracket m, whereby the wrapping-material is fastened and cut off; the hooks 20 are depressed to release the package and return to engage the loose end of the strip, and the roller u returns under the strip to form the base of the next package.

Class 100 (1) The frame 2 of the chain delivery of a sheet printing machine, pivoted on the machine frame 1, e.g. on a shaft 3, can be swung to different positions through supporting means pivoted to the swinging frame, e.g. two double-armed levers 11 secured to a shaft 10 journalled in that frame, and held in these positions by springs 7, 15. Furthermore, in the operating position, shown in full lines in Fig. 1, the pivotal securing means 10 and further pivots 12 of the supporting means lie in the median plane II-II of the swinging frame. A rod 18 and chain wheels 4, 5, are borne by the frame 2. The ends of the rod locate in slots 20 in arms 14 of the machine frame 1 in the operating position and rotation of the rod locks the frame 2 in that position by securing those ends. As the frame 2 is swung, each lever 11 turns about its end 12 which moves horizontally in a track 13 in one of the arms 14. Torsion springs 7, secured at their outer ends 6 to the swinging frame 2 and at their inner ends to a disc 9 fixed on the shaft 10, counteract the turning moment on the frame due to its weight. The springs 7 may be supplemented by springs 15 attached at one end to arms 16 of the levers 11 and at the other end either to the frame 2 as shown, by a screw which adjusts the spring tension, or to the machine frame 1. The swinging frame with its springs and levers may be assembled away from the machine, the levers 11 being locked, with the springs under tension, to be freed when the device is positioned on the machine.
