Title: Static rectifier assemblies
IPC: H02M7/162
Filed: 1970-07-30
Abstract: 1315010 Rectifying BROWN BOVERI & CO Ltd 30 July 1970 [1 August 1969] 36882/70 Heading H2F A rectifying system comprises a group of parallel-connected controlled rectifiers arranged to be turned on by a firing pulse occuring at or near the beginning of each half cycle of appropriate polarity and coupled by an inductor to a load (such as a motor or battery) having a reverse voltage U5. In such an arrangement the load current i G  following a firing pulse at t2 may be less than the holding current of some of the parallel-connected rectifiers so that other such rectifiers may be overloaded later in the cycle. To avoid this, a post-firing pulse is generated at t4 when the load current has passed a critical value i<SP>1</SP> G , by monitoring the load current, e.g. by means of a Hall effect device. The postfiring pulse may be generated when the total load current passes the critical value i<SP>1</SP> G  or when the load current of a group of parallelconnected rectifiers passes the critical value. Alternatively, the post-firing pulse may be generated in response to any rectifier passing current exceeding the maximum permissible for that rectifier. Fig. 1 (not shown) relates to the rectifying system comprising a bridge of two thyristors and two diodes but may comprise a centre-tapped circuit.

Filed: 1946-12-16
Abstract: 620,784. Clutches ; gearing for stopping and starting machinery. LUCAS, Ltd., J., and PRICKETT, A. D. Dec. 16, 1946, No. 36983. [Class 80 (ii)] An axially engaged friction clutch'engaged by spring-pressure and disengaged electromagnetically has posts extending from the driving and driven members which posts slidably carry an additional part limiting the axial movement of the driving and driven members, the posts having adjustable abutments for positioning the additional part. A friction material faced driven disc 16 of the clutch is splined to the driven shaft 13 and is pressed between a first driving member 1 attached to the crankshaft 3 and a second driving member 18 by the springs 21. The member 18 is limited in its axial movement by the heads 20 of a series of posts 19, and carries an annular iron magnet armature 22 having chamfered peripheral faces 23. These faces co-act with similar faces of an annular electromagnet 6 secured to the driving member 1 by collared posts 4 having nuts 10 to adjust the relative axial positions of the members 1 and 6, against the springs 8, for wear. The clutch electromagnet winding 32 is controlled by the circuit shown in Fig. 2 in which 28 is an engine driven dynamo. On closing the ignition switch 30, current flows from a battery (not shown) to the dynamo and excites a relay 29 to close a two-way switch 31 to energise the windings 32 and release the clutch. As the engine speeds up the dynamo overcomes the battery and the clutch is progressively engaged under the action of the springs 21. At normal running speed the dynamo feeds through the cut-out and the relay remains idle, but disengagement of the clutch is produced by closure of a manual switch 33.

Title: Improvements in wagon tipping apparatus
IPC: B65G67/00
Filed: 1930-12-12
Abstract: 367,083. Tipping-apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and MARSHALL, C. H., of Fraser & Chalmers Engineering Works, Erith, Kent. Dec. 12, 1930, No. 37506. [Class 78 (iv).] In a wagon tipping apparatus in which a cradle comprises members 4, 6, pivoted at 7, 9, respectively to a member 5, the member 4 carries a pivoted platform 2 for supporting the wagon and the member 5 carries a bolster 8 and a stop 8a, so that when the member 4 is rotated about the pivot 7, the platform 2 first tilts the wagon against the bolster 8 and then raises it to abut the stop 8a. The members 4, 5 now rotate about the pivot 9 until the wagon engages a bar 10 on the member 6, whereupon the cradle rolls on the surface 11 of the member 6 along the guides 12 until the wagon contents are discharged into the truck 30. The cradle is actuated by ropes 16 which are connected at one end to drums 22 driven by a motor 26 and pass over pulleys 21 on a trestle-like structure 17 to pulleys 15 on arms 13. These arms are pivoted at 14 to the member 4 and act as slings to assist in clamping the wagon in the cradle in the inverted position. The contents of the wagon fall on to a member 31 which breaks them up should they form a solid mass inside the wagon. Stops 32 ensure that the cradle will roll back under its own weight to the untipped position. Racks 34, 35, mounted on a lever 33 and the member 5 respectively are normally held disengaged by a stop 36, but when the cradle rotates about 9 the rack 35 moves forward into engagement with the rack 34. If the pressure on the sides or springs of the wagon due to the clamping members tends to become excessive, the lever 33 takes the excess load. A rope 37, fastened at 39 and connected to the member 6 at 38, prevents the surface 11 slipping on the guides 12.

Abstract: 346,414. Engine valve-gear. FOLKES, G. E., 5, Corporation Street, Birmingham.- (Pintsch Akt.-Ges., J. ; 71, Andreasstrasse, Berlin.) Dec. 11, 1929, No. 37960. [Class 122 (ii).] In an automatically-controlled apparatus for lifting and lowering conveying trucks the pressure fluid (compressed air) employed for performing the lifting action is conducted through a slide valve 9, which is controlled by the movement of the hoisting piston 2, to a subsidiary piston 15, which actuates a slide 16 for reversing the valves of the hoisting cylinder 21. The arrangement of valves is such that the hoist reciprocates slowly and dwells at each end of the stroke, the length of dwell and the rate of reciprocation being adjusted by a valve 14, which controls the rate of flow of air into and out of the subsidiary cylinder 13, and by valves 25, 26, respectively. The inlet and outlet valves 17, 22 of the hoisting cylinder are opened by springs and closed by air pressure. In the position shown the hoist is moving upward and air pressure behind the outlet valve 22 keeps it closed while the inlet valve 17 is open. At the top of the stroke the collar 6 on the housing of the hoisting piston 2 engages the stop 7 and pulls up the slide 9, the cylinder 13 discharges to atmosphere through the valve 14, the piston 15 rises slowly, after a slight interval air pressure gets behind the inlet valve and closes it, and the pressure is released from behind the outlet valve, which opens so that the hoisting cylinder discharges through the valve 25 and the hoist descends. At the bottom of the stroke the slide 9 is pulled down whereby the valves are reversed and' hoisting begins again. The apparatus is stated to be applicable to lifting trucks bearing metal castings from the lower end of an inclined conveying truck to the higher initial part thereof.
