Title: Improvements in mechanical couplings for the control of adjustable apparatus
IPC: H03J1/06
Filed: 1939-07-21
Abstract: 531,423. Linkwork. STANDARD TELEPHONES & CABLES, LTD., PRICHARD, R. E., and JESSOP, R. F. July 21, 1939, No. 21252. [Class 80 (iii)] [Also in Groups XXXVI and XXXVII] A slide is rectilinearly movable by means of a single manual control member, with respect to a second slide, which is rectilinearly movable with respect to a framework in a direction transverse to the first. The invention is shown applied to a variable resistance comprising two resistance elements or pairs of resistance elements independently adjustable by a common control member and particularly applicable for image centreing in television receivers as described in Specification 526,361, [Group XL]. A metal frame plate 1 is covered with a sheet of insulating material 2 and carries a cruciform sheet insulator 3 on the arms of which are wound resistance elements 4. Slidable over the frame plate is an insulating plate 5 carrying four contact pins 6, 6a, which are pressed against the resistance elements 4 by means of a backing plate 7, which is slidable over four studs 8 fixed to the frame plate, the backing plate 7 being pressed against the carrier plate by springs 9. The centre portion of the backing plate 7 is cut away to allow free movement of the carrier plate 5. One or more of the contact pins 6, 6a has a spring-loaded plunger 6b. The carrier plate 5 is free to move in any direction in its own plane, vertical motion varying one pair of resistance elements and horizontal motion varying the other pair. The carrier plate 5 is operated by a lever 11 having a ball-and-socket mounting in the frame plate 1. The lever 11 may be rotatable about its axis for controlling another variable element, e.g. for controlling the magnification. In order to prevent rotation of the carrier plate 5, a guide plate 15 is provided having horizontal slots through which pass the studs 8, which studs have shoulders 8a, against which the guide plate rests and is free to move horizontally. The guide plate 15 also has vertical slots 15b through which pass two of the contact pins 6 so that the contact pins and contact carrier plate are constrained to move vertically with respect to the guide plate. The resistance elements 4 may be replaced by rows of contact segments. The mechanism may be adapted for the adjustment of mechanical valves or for the control of other sliding motions such as in variable gears.

Title: Process for producing metal from metal oxide pellets in a cupola vessel
IPC: C21B13/00
Filed: 1974-05-14
Abstract: 1474624 Smelting pelletized ores R F OBENCHAIN 14 May 1974 [31 May 1973] 21303/74 Heading C7D  Molten metal, e.g. Cr, Fe-Mn, or preferably Fe, is produced in a cupola from pellets containing metal oxide and sufficient carbonaceous material sufficient to effect complete reduction of the oxide. Alternate layers of coke and pellets are charged to a cupola 1 above a coke bed 7 heated by blasts of air, O 2  or preferably O 2 -enriched air through tuyeres 8. A flux, e.g. CaO, CaCO 3 , MgCa(CO 3 ) 2 , Na 2 CO 3  or CaF 2  is added to the charge, together with a desulphurisation agent, e.g. soda ash, CaC2, if required. The pellets are formed from particulate ore, e.g. fines, furnace dust, mill scale, with e.g. fine coal, coke, petroleum coke, and water, with a binder, e.g. cement, lime, if extra strength is required, e.g. for the initial charge. The pellets are preferably formed on a disc 10 and are fed by conveyers to the cupola, during which the pellets may be dried by off-gases from hoods 24, 25. The off-gases may also be used to pre-heat the air and/or O 2  blast, e.g. to 2600F. Air and/or O 2 , and optionally natural gas, petroleum or powdered coal is introduced through tuyeres 8a, 8b to acid the heating of the coke. The molten metal containing 0À02 to 4% C falls through the coke bed and is tapped at 9. Scrap and pig iron may also be added to the charge.

Title: Improvements in or relating to steering gear for trailers
IPC: B62D13/04
Filed: 1937-08-03
Abstract: 497,447. Steering trailers. VIBERTI, C. Aug. 3, 1937, No. 21428. [Class 79 (v)] The steering mechanisms of the front and rear wheels of a trailer are connected together by links 6, 6a meeting at an obtuse angle at a connecting bolt 7 working in a fixed guide in a housing 16, the arrangement being such that substantial steering movement only, as distinct from slight oscillation, of the front wheels is transmitted to the rear wheels. The trailer shown is adapted to be drawn in either direction, a draw-bar 1 at either end being pivoted at b to the chassis, and connected by a steering lever 2, working on a fixed pivot a, to a divided track-rod 4 of the corresponding wheels. An arm 5 fixed on each lever 2 is pivotally connected to the corresponding link 6, 6a. The guide for the bolt 7 comprises a central section na, constituted by transverse slots in upper and lower plates 8 in the housing 16, and opening into channels u and v terminating respectively in end sections 19 and 19a (see full-line disposition in Fig. 4). The bolt 7 is normally in the centre of the central section m, and the link 6a of the rear wheels is at rightangles to the central section. Slight oscillation of the front wheels causes displacement of the bolt 7 along the central section m only of the guide, and such movement is not appreciably transmitted to the rear wheels owing to the link 6a being at right-angles to the path of movement of the bolt. Substantial steering movement, however, causes the bolt 7 to travel further, into the channels u and 19 or v and 19a, so that steering movement is then transmitted to the rear wheels. In order to enable the trailer to be drawn in either direction, the plates 8 are rotatably mounted in the housing 16 so that their slots m can be set at right-angles to either link 6 or 6a. The channels u and v are formed between edges 8a and 8b of the plates 8 and fixed walls 18 and 17 in the housing 16. When the plates 8 are turned from the full-line position to their alternative position, shown in broken lines, the channels u and v are replaced by channels x and y. The deflection of the rear wheels is less than that of the front wheels when the bolt 7 is in the channels u, v, x, or y, but becomes equal when the bolt enters the end channels 19 or 19a. The plates 8 may have a third position in which the guide section m directly connects the end channels 19 and 19a to provide for equal deflection of the rear wheels in all positions of the front wheels.

Title: Improvements in or relating to disc brakes
IPC: F16D59/02
Filed: 1956-07-13
Abstract: 796,841. Disc brakes. SCHIESS AKT.-GES. July 13, 1956 [July 15, 1955], No. 21665/56. Class 103 (1). In a braking device for use in connection with machine tools, the shaft 3 is rotatable with the part to be braked, for example the face-plate of a lathe, and a plurality of brake discs 14 and rotatably driven by outer disc carrier 6 secured to flanged sleeve 5 keyed to the rotatable brake shaft 3. Discs 14 are pressed by spring means 15 against a plurality of discs 14<SP>1</SP> rotatable with inner disc carrier about shaft 9, which is fixedly connected to brake shaft 3, without causing any braking effect on the shaft 3 when an electromagnetic disc brake 21 is not energized. The electromagnetic disc brake 21 comprises a disc rotatable with sleeve 25 keyed to inner disc carrier 8 of the mechanical disc brake. The brake torque of the electromagnetic brake is about 20 per cent greater than the brake torque of the mechanical or spring-loaded brake. In operation, when the outer disc carrier 21 of the electromagnetic brake is energized, the connecting sleeve 25 prevents the discs of the carrier 8 from further rotation. A braking action is thus exerted on the discs of the carrier 6, since the two sets of discs are pressed together by the springs, thereby braking the shaft 3 to which the carrier 6 is fixed.
