Title: Improvements in and relating to ingot handling dogs
Inventor: SMITH LESLIE DREW
IPC: B66C1/42
Filed: 1969-05-29
Abstract: 1,255,671. Ingot handling device. BRITISH STEEL CORP. 4 May, 1970 [29 May, 1969], No. 27230/69. Heading B8H. A device for handling ingots comprises dog arms 10, 11 pivoted at 15 and whose upper lever portions 17, 16 are pivoted by levers 50 to a clevis plate 60, the arms 10, 11 being maintained in an open position prior to gripping an ingot by means of a tumbler hook 67 pivotally mounted at a pin 66 on the plate 60 and whose bight 71 engages the pivot 15. To lift an ingot the device is lowered e.g. by means of a hook engaged in a slot 64 in the plate 60 and the dog arms 10, 11 abut the upper surface of the ingot thus permitting the plate 60 to be lowered towards pivot 15 and a cam surface 68 of hook 67 abuts the sleeve (31), Fig. 3 (not shown), of pivot 15 causing hook 67 to disengage the pivot 15. Continued downward movement of plate 60 results in its lower part 65 abutting a guide member 80 causing progressive rotation of hook 67 about pin 66 until it comes to rest against a stop member 81 as shown in Fig. 6 (not shown). On raising the plate 60 the dog arms 10, 11 are drawn inwardly by means of the link arms 50 and dog bits 23 grip the ingot, the hook 67 being drawn away from the stop member 81 such that its cam surface 69 is adjacent the upper side of the pivot 15. To release the ingot the device is lowered until the ingot is resting in position and continued lowering results in cam surface 69 bearing against pivot 15 to tilt the hook 67 rearwardly until its barb clears pivot 15 and presents the bight 71 to the pivot 15 whence upward movement of plate 60 results in the arrangement shown in Fig. 1 such that the arms 10, 11 are in the open position and the device can be lifted clear for use with another ingot.

IPC: H04Q3/00
Filed: 1966-06-17
Abstract: 1,177,955. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 26 May, 1967 [17 June, 1966], No. 27240/66. Heading H4K. A line finder/final selector comprises primary, secondary and tertiary cross-point switches AS, BS, CS, Fig. 1, controlled preferably by reed relays and linking subscribers' line circuits SLC with transmission bridge circuits TRS so as to give complete access between them, and the horizontals of the BS switches are divided into two sections 1B, 0B, the former connected to the verticals of the CS switches and to the latter to register access circuits RAC leading to an external switching network. The switches AS1 ... 20, BS1 ... 5 form a unit SU, Figs. 2, 3, and five or a smaller number of such units may be associated with switches CS1 ... 5 to serve a 3-digit subscriber group. Although 20 bridge circuits TRS are shown, a greater number may be required in the case of a subscriber group having a high calling rate, and arrangements may be provided for adding to an existing installation. The CS switches are associated with two common control circuits CCA, CCB which are used alternately and include a register responsive to 3 digits preferably received in VF form, as in Specification 1,122,141 for the completion of terminating calls. The AS and BS switches of each unit SU are served by common control circuits CCD, CCE which are individual to the several units and act in conjunction with the circuits CCA, CCB on terminating calls to mark an idle path to the wanted subscriber. The control equipment deals with busy and faulty conditions, and should a caller try to make the same call a second time arranges that an alternative path is used. In the case of originating calls, only the relevant circuits CCD, CCE are effective to determine an idle path from the line circuit SLC to an idle register access circuit RAC, whereupon the calling loop is extended to initiate the setting up of the required connection. If the wanted subscriber is served by the same unit SU, a main register controls the connection by way of a bridge circuit TRS to the appropriate line circuit SLC therein. Order-of-choice circuits come into use in the event of simultaneous originating or terminating calls. Specification 1,122,142, which relates to a group selector comprising primary and secondary cross-point switches, is referred to.

Title: Process of and apparatus for the production of molten iron or steel by the direct method
IPC: C21B13/08
Filed: 1933-10-06
Abstract: 424,663. Extracting iron; treating ores. SACHTLEBEN AKT.-GES. FUR BERGBAU UND CHEMISCHE INDUSTRIE, 163, Eintrachtstrasse, Cologne, Germany. Oct. 6, 1933, No. 27594. Convention date, Oct. 6, 1932. [Classes 72 and 82 (i)] [See also Group XII] In the production of molten iron or steel, by the direct reduction of ores &c. in a moving furnace, the silica content of the charge is adjusted, either by the employment of ores containing the requisite amount of silica or by the addition of siliceous materials, so that while the temperature increases, spongy iron and ferrous silicate are formed simultaneously, the latter then reacting with the lime present to liberate ferrous oxide which is reduced to the metallic state and melted with the spongy iron. The charge may be preheated before reduction and the bulk of the volatilizable substances such as sulphur, zinc, &c. will then be expelled or, if there is no preheating, during the reduction of the ore. Fluxes such as fluorspar which reduce the melting point of the slag may be added to the charge and the lime required for the decomposition of the silicates may be added to the charge before or after the preheating of the latter or before its introduction into the reducing furnace or when the charge is already in the furnace. The ore which may be roasted or agglomerated is mixed with about 20 per cent of reducing carbon and is conveyed by the endless band 1 and pipe 2 into a rotary preheating furnace 3 where the more volatile metals such as zinc are removed, e.g. as described in Specification 225,842, [Class 82 (i)]. The preheated material then passes into a shoot 4 where it is mixed with carbon and other additions required for the reduction of ore and thence into a rotary furnace 5 heated by a coal dust burner 6. The waste gases from the furnace 3 pass into the flue 10, past the air preheater 11 into a conduit 12 and thence into a filtering device in which the oxides in the gases are precipitated therefrom. A fan 13 forces air through the preheater 11 and pipe 14 into the burner 6. In a modification, the furnace 3 is dispensed with, the material before entering the furnace 5 being treated in a roasting or sintering apparatus and then passing over a screen into the furnace.

Vapours leaving the head of a distillation column pass through tubes 16 into an aircooled condenser comprising an annular casing 2 which encloses a plurality of vertical tubes 3, supported in upper and lower plates 2', 2" while cool air is forced down inside the tubes 3 by blower 12. The vapours condense on the outer surfaces of the tubes, and the condensate collects on plate 2". Part of the condensate refluxes back to the column through tubes 16, and the remainder is withdrawn through lines (not shown). In order to control the temperature part of the warm air discharged from the lower ends of tubes 3 is drawn up, via slit 14 and inner space 18, by three symmetrically-placed fans 13 (only one of which is shown) into dome 8 where the warm air mixes with the cool air drawn in by blower 12. Inert gases are withdrawn from the top of casing 2 through pipes 6 which lead into circular pipe 5. Radial partitions 4 divide casing 2 into several sections. The tubes 3 may contain internal ribs. The tubes 3 may be replaced by hollow rectangular channels supported vertically.
