Title: Improvements in or relating to apparatus for opening and closing outlets of containers for molten metals
IPC: B22D41/14
Filed: 1962-01-22
Abstract: 962,924. Discharging molten metals; ladle stoppers. BROWN, BOVERI & CO. Ltd. Jan. 22, 1962 [Jan. 24, 1961], No. 2191/62. Heading F4B. The stopper 4 of a ladle or induction furnace 1 is so formed that, in the closed position, a narrow annular space filled with solidified metal remains between it and the inner wall of the outlet 2. When the stopper is to be withdrawn from the outlet the solidified metal is melted by a mains frequency induction winding 6 surrounding a tubular outlet extension 2. The metal in the space 5 may be solidified by passage of coolant through the winding 6 whilst the latter is deenergized or by provision of a hollow, internallycooled, stopper. The winding 6 may form part of a structure separate from the ladle and only moved to a position where it surrounds the extension 2 when the stopper is to be withdrawn.
Patent GB-1535353-A (GB)
Title: Apparatus for stretching dough material
IPC: A21C3/02
Filed: 1976-01-20
Abstract: In the device, the dough is stretched by means of a plurality of rollers (51), which are guided on a closed path (B) having a lower straight section (x), on the upper runs of conveyor belts (15, 21, 23) arranged below the said straight section (x). A gap is provided between the upper runs of adjacent conveyor belts (15, 21; 21, 23) and these adjacent conveyor belts come into contact with one another at a point (P) below the plane in which the upper runs of the said conveyor belts are situated. Contact between the conveyor belts causes the flour remaining on the upstream conveyor belt to be brushed off onto the next downstream conveyor belt. The dough is not supported between two successive runs of the conveyor belts. This means that the accumulations of dough generated after each stretching action by the rollers are kept small, so that no deep folds or cracks appear in the strand of dough during the subsequent stretching operation in a relatively narrow gap between the rollers and the more rapidly moving conveyor belt. <IMAGE>

Filed: 1956-01-26
Abstract: 782,637. Combustion apparatus. BABCOCK & WILCOX, Ltd. Jan. 26, 1956 [Jan. 27, 1955], No. 2587/56. Class 51 (1). " Black liquor " is burnt in a furnace simultaneously with a high heat content fuel. The furnace 13, Fig. 1, comprises water-tube lined chamber 35, hopper 18, vertical gas pass 135 and a lateral gas pass 40 leading to an economizer and an air heater. The upper portion of the chamber 35 is also lined with refractory 43 whilst the tubes 33 forming the rear boundary of chamber 35 and the front boundary of pass 135 are divided into two groups each group being bent outwards at its lower end to connect with a lateral header 34, Fig. 2. Gases passing from chamber 35 up the pass 135 flow over superheater tubes 36 and steam generating tubes 12. Air from the air heater passes to a box 54 in conduits 58 one each side of the furnace structure. Each conduit 58 has a branch 60 which supplies air to burners 45 which operate on " black liquor." The front wall of the furnace accommodates a pulverized coal burner 48 to which fuel is supplied from a mill 50 by hot air being extracted from the box 54 and forced through the mill to entrain the coal particles. The box 54 supplies secondary air to the burner 48 and a valve 55 and tempering air inlet 57 are provided in the air conduit 53 to regulate rate and temperature of air supplied to the mill. Due to reversal of flow solid matter tends to drop out from the combustion gases as they leave the chamber 35. This matter is collected in hopper 18 and passes down a refractory lined chamber 61 to a sluice-way 62 for periodic or continuous removal.

Abstract: 398,713. Controlling variable-speed gearing. HERBERT, SIR A. and HARRISON, H. T., c/o Herbert, Ltd., Canal Road, Edgwick, Coventry. Jan. 27, 1933, No. 2628. [Class 80 (ii).] Preselector control mechanism for change gearing comprises a multiple cam 20, Fig. 2, which is turned to make selection while a gear train is operative and then moved bodily first to neutralize the change gearing and then to introduce the selected ratio train. Striking forks 9, 10, 11, Fig. 1, of four-speed and reversing gearing are operable by angular displacements of arms 12, 13, 14 which extend towards the cam 20. The cam device 20 has a number of groups of slots in line, one group for each forward speed and a group for neutral and one for reverse, six groups in this case, and in each group there is a slot for each of the three arms 12, 13, 14. The selective movement turns the cam 20 to bring a group of slots opposite the arms. In the selection for neutral, shown in Fig. 2, the slots 39 are coplanar. The mouths of the slots 39 are flared as shown at 25 so that as the cam 20 is advanced towards the arms, any arm which is out of its mid position is engaged and brought to mid position by one of the flared surfaces 25. A slot operative to bring in a selected gear ratio is shown at 36 in Fig. 8 which shows a modification. In the position of Fig. 8, radial slots such as 39, Fig. 2, have centralized the other arms 13, 14, not shown in Fig. 8. The cam device 20 is shown in Fig. 1 as comprising three disc portions 21, 22, 23, one for each arm, these discs being keyed on a shaft 24, each disc having six radially-extending slots of which a sample is shown in Fig. 8. The shaft 24 is turned to select by two cables 26, Fig. 2, wound on a drum 28, Fig. 1. The shaft 24 is journalled in brackets 29 adapted to slide on guide rods 30, Fig. 2. When a pull is applied by suitable means 31, the brackets 29 are advanced against a return spring and the selected row of slots is advanced to envelop the arms 12, 13, 14 and constrain them positively to relative positions corresponding to the selected ratio. In the modified arrangement of Fig. 8, there is a locking lever 45 for each of the arms 12 &c. adapted to lock the arm in neutral and in both engaged position. The locking levers 45 are all raised out of engagement on the advance of the cam 20 by inclines 44 on the brackets 29. An arrangement by which the advance of the cam 20 is effected by the engine clutch pedal of a vehicle is described in Specification 398,705.

Title: Improvements in or relating to power unit for propelling a machine along railway tracks
Inventor: JACKSON CORWILL
IPC: B61D15/12
Filed: 1951-02-02
Abstract: 678,783. Rail-truck movers. JACKSON VIBRATORS, Inc. Feb. 2, 1951, No. 2632/51. Class 79(i) An auxiliary power unit for propelling a rail vehicle comprises a pivoted frame hung from supporting bars fixed to the vehicle, the frame having a draft connection and driven rail-engaging wheels which can be brought into driving engagement with the rails when the frame is pivotally moved. Pivotal movement of the frame may be effected by manually controlled powerdriven means. As shown, the rail vehicle 4 to be propelled has a pair of supporting bars 6 fixed thereto. Resting on these supports is the power unit comprising a U-shaped handle 58 with lateral extensions 59, from which depends a front pair of uprights 60 and a rear pair of hangers 10, resting on the supporting bars 6 by adjustable eccentrics 11. Pivoted to the bottom of hangers 10 by transverse pivot 13 is the main frame 14, 9 which carries the power unit, transmission and rail-engaging wheels 21. The coupling member 8 on the vehicle is connected by a king-pin 17 through a draw-bar 15 to the frame membera 18. Power is transmitted from the engine 29, driving belts 30 and reduction gear 32 to sprocket 34, thence to sprocket 35 fast with axle 19 and so to rubber-faced driving wheels 21. The axle 19 is mounted in bearings 20 secured to the main frame 9. The main frame includes a stirrup member 28 having a vertical rod 27 attached to one end of a spring 25, whose other end is carried by the draft connection. Thus the main frame, power unit and transmission are resiliently suspended about the pivot 13, 18 in such a manner that the driving wheels are normally held clear of the rails, and so that depression of the frame against the action of spring 25 brings the continuously rotating driving wheels 21 into contact with the rail to propel the vehicle. This movement is power operated as follows: Attached to the output shaft 33 of the reduction gear is a pulley 42 with a V groove. Located in the groove is a length of V belting 41, one end being attached to the pivoted lever 50 and the other end to the lever 37 pivoted at 38 on the draft coupling. Integral with lever 37 is a crank 39 having a roller 40 bearing on the stirrup 28. The V belt 41 can be pressed into contact with the continuously rotating pulley 42 by a roller 47 on the end of pivoted yoke 46 when the latter is rocked by moving handle 51. This causes the lever 37 and crank arm 39 to be moved to depress the main frame and hence the driving wheels against the action of spring 25.
