Title: An improved method of generating vapour and improvements in or relating to vapour generating plant
Inventor: WOOTTON WILLIAM ROBERT
IPC: G21D5/14
Filed: 1959-12-23
Abstract: 966,971. Direct contact steam boilers. BABCOCK & WILCOX Ltd. Dec. 9, 1960 [Dec. 23, 1959], No. 43690/59. Heading F4A. A method of generating vapour from a liquid, includes producing an initial stream of superheated vapour under pressure, supplying the superheated vapour to a direct-contact vapour generator to produce an augmented stream of saturated vapour and producing a further stream of saturated vapour in at least one succeeding direct-contact vapour generating stage by superheating the stream of saturated vapour from the preceding stage and supplying the superheated vapour to a direct-contact vapour generator of the said succeeding stage. As shown in Fig. 3, steam from an auxiliary conventional boiler 12 is heated in a superheater 9, heated, e.g. by a liquid-metal nuclear reactor coolant, and is passed through a pipe 3 and a nozzle 4 to heat water in a tank 1 and produce saturated steam which, from a scrubber 5, is forced by a high-pressure pump 7 to the superheater 9 part of the output of which is also fed, through a pipe 10, to the first of a cascade of water drums 19, 26, 33, 40, 47. The latter are interconnected by low-grade superheaters 23, 30, 37, 44, 51, the last of which leads to a point of utilization 11. The water drums are fed with varying percentages of the total feedwater. In a modification, Fig. 4 (not shown), the whole output of steam from the superheater 9 is led through the pipe 3 to the drum 1 the drum 19 being supplied with steam which is drawn through a scrubber within the tank 1 and which passes through a further superheater. When used in conjunction with a nuclear reactor 55, Fig. 5, all of the superheaters 9A, 16, 23, 30, 37, 44, 51 are disposed within a reactor-coolant pressure vessel 56 which is mounted on steelwork 59 and supports the water drums 1, 19, 26, 33, 40, 47 on opposite sides of the circulating pump 7 driven by a small condensing steam turbine 60. The drum 1 and the pump 7 may be omitted in which case the superheater 9A is replaced by a superheater supplied with saturated steam from the conventional boiler 12 which is kept in continuous operation. Specification 846,996 is referred to.

Title: Improvements in or relating to Disc Brakes.
IPC: F16D65/14
Filed: 1967-10-03
Abstract: 1,186,228. Disc brakes. ALFRED TEVES G.m.b.H. 3 Oct., 1967 [10 Oct., 1966], No. 45028/67. Heading F2E. In a disc brake mechanism brake adjuster which includes a force transmitting member 5 comprising a threaded pin 6 screwed into a socket 7 is disposed between a piston 2, which bears on a brake pad carrier, and a mechanical actuator shaft 3, and when the brake mechanism is actuated an arcuate ratchet 8 which is pivoted about the shaft 3 and is driven by it through compliant means, engages a toothed rim 12 on the socket 7 and rotates the socket 7 so as to lengthen the force transmitting member 6, 7 until the compliant means is overcome by the frictional resistance of the engaging thread in the force transmitting member as the brake pad carrier is urged towards the brake disc. The arcuate ratchet is in the form of a lever 8 and is connected to the shaft 3 by the compliant means in the form of a spring which allows the lever to rotate with the shaft 3. When the actuating lever 4 is moved to apply the brake the lever 8 moves through an amount corresponding to the brake clearance before its teeth engage with teeth 12 on the exterior of the socket 7. On further rotation of the actuating lever 4 the teeth on the ratchet lever 8 rotate the socket 7 which co-operates with a threaded pin 6 to move the pin and socket apart so as to compensate for wear of the pad. This movement continues until the pad contacts the disc when the frictional forces on the slack adjusting socket 7 are greater than the adjusting force which can be transmitted to the socket 7 by the ratchet lever 8 due to the compliant connection between the ratchet 8 and the shaft 3. The lever 4 which may be operated by a Bowden cable and ratchet lever 8 are returned to the starting position on release of the brake by a spring, the teeth of the ratchet lever 8 jumping over the teeth 12 of the socket. The pin 6 is retained in the piston 2 by a pin 9 and the socket 7 is secured to the shaft 3 by a pin 17 which is fixed to the shaft and is located within a groove 18 in the socket 7. The adjuster 5 is reset for renewing the pads by removing a circlip (16, Fig. 2, not shown), moving the shaft 3 axially so that teeth (15) on a further lever (14) engage the teeth 12 of the socket 7 and rotating the lever 4.

Title: Process and apparatus for producing anhydrous magnesium chloride
IPC: C01F5/32
Filed: 1974-10-28
Abstract: 1478864 Anhydrous magnesium chloride ANIC SpA 28 Oct 1974 [31 Oct 1973] 46609/74 Heading C1A Substantially anhydrous magnesium chloride substantially free of magnesium oxide and oxychloride is prepared by chlorinating a metal of the hydrated chloride with a mixture of chlorine and oxygen in molecular form in the presence of a carbonaceous material which reacts with the oxygen in molecular form to form carbon monoxide during chlorination. A preferred method consists of passing the molten salt down through a column of carbonaceous material, e.g. coke whilst chlorine and oxygen are passed up countercurrently. A further preferred method consists of firstly drying the hydrated salt until it has a water content of from 2-5% by weight and a magnesium oxide content of from 2-5% by weight. This dried salt is then conveyed, via a screw feed 14, to a heated furnace assembly 1 comprising at least three chambers 9, 10 and 11, in a steel crucible 2 with refractory dividing walls 7 and 8. Heating may be attained by an electric heating element between the crucible 2 and the saltresistant refractory bricks 3. The dried salt is introduced into the melt chamber 9 where separation into molten salt, sinking and floating impurities occurs. The molten salt then passes through the window 16, in the separating wall 7, into the chlorination chamber 10. The melt is pumped by pump 31 through the heated pipes 30 and 29 to the top of the chlorination tower 18 which is packed with coke 28. At the same time chlorine and oxygen are fed into the base of the tower via the heated pipe 35 to an inlet pipe 34 and allowed to pass upwardly against the downward stream of molten salt. The circulation of the molten salt may be maintained by more than one pump. The chlorination chamber overflows over a weir on the separating wall 8. As a preferred feature the tower may be easily replaced, furthermore several interchangeable towers may be used. The electric heating element may be replaced by other forms of direct heating, or the apparatus may be modified by removal of the crucible 2 wherein the molten salt is contained by the salt resistant bricks 3 and heating is then effected by passing an A.C. current through the molten salt. The pure salt MgCl 2  so made is used in the electrolytic magnesium cell.

Abstract: 1453959 Balancing apparatus REGIE NATIONALE DES USINES RENAULT 5 Oct 1973 [12 Oct 1972] 46641/73 Heading F2U [Also in Division G1] In an apparatus for determining the dynamic imbalance of a rotary body, e.g. a crankshaft, which is to have an inherent residual imbalance such that it may later form part of a balanced assembly when associated with other components in use, the rotary body 2, Fig. 1, is carried on supporting bearings 4 in a structure which is driven in rotation about an axis 3, this structure being supported relatively to a fixed ground plane by resilient members 1 which allow freedom for the structure including the rotary axis 3 to be movable bodily in a plane of oscillation parallel with the horizontal ground plane, and portions of the structure incorporating a cradle 5 having two eccentric masses 5a, 5b, with a bar 11 carrying an adjustable cursor mass 10, together form an assembly which is statically balanced but which can contribute a dynamic imbalance moment of a magnitude adjustable by alteration of axial position of the cursor mass 10 on the bar 11, when the assembly is rotated, thereby providing a means of achieving a temporarily dynamically balanced combination of the apparatus and the inherently unbalanced rotary body under test. In order to check the dynamic imbalance of a crankshaft, e.g. of a three-throw type as in Fig. 1, it is necessary to provide such a pre-determined additional dynamic imbalance in simulation of the dynamic imbalance which will in use be contributed by the connecting-rod bearings, and the present apparatus may be used for determining the acceptability of dynamic balancing characteristics of crankshafts alone, during their manufacture, by incorporating an appropriate simulation imbalance during the test operation. Pre-set stop devices for locating the cursor mass 10 in chosen axial positions may be provided, and actuator jacks may be fitted for shifting the mass 10 between these positions, thereby permitting the apparatus to be used for checking crankshafts of differing designs in rapid succession. An alternative embodiment, Fig. 7, has a first imbalancegenerating mass in the form of an eccentric drum 21 located coaxially at one end of the rotary body 2, and a second imbalance-generating mass which takes the form of an eccentric collar 18 sliding on an extension shaft 19, coaxially on axis 3. The collar 18 is driven in rotation by a layshaft 24 through a spur gear 23, and its axial location is adjustable by means of a jack 27. In the arrangements of Fig. 1 and Fig. 7 the eccentric imbalancegenerating masses are maintained in antiphase coaxial relationship at all times, but in further embodiments the two masses may be on separate parallel axes, and may be rotated in opposite directions.

Filed: 1968-10-02
Abstract: 1,243,806. Automatic thickness control. WESTINGHOUSE ELECTRIC CORP. Oct.2, 1968 [Oct.23, 1967], No. 46710/68. Heading G3R. In a tandem or a reversing rolling mill, at least one rolling stand is controlled by a roll force gauge control system in which the roll force and the unloaded roll spacing are measured and a calculated delivery gauge is calculated therefrom and compared with the actual delivery gauge to derive a control signal to adjust the screwdown position of the rolls, if necessary. As shown in Fig. 1, a tandem rolling mill has n stands, each of which has a load cell LC for measuring the roll force and a screwdown position detector SPD. An X-ray gauge 20 measures the actual workpiece gauge at the exit of the last stand and the "mass flow" delivery gauge for each other stand is calculated using the speed of the workpiece at the stand as measured by a tachogenerator T, modified if necessary by a slip factor. Each stand is interrogated in turn in an automatic sequence under the control of a computer 18 and the "roll force" gauge is calculated making allowance, if necessary, for non-linearity of the mill spring. If the calculated "roll force" gauge is within a certain "validity" range (e.g. within 10% of the actual "mass flow" gauge), the screwdown position is adjusted, the amount of adjustment being determined by a weighted mean of the new screwdown offset (10%) and the previous one (90%). If the calculated gauge is outside the "validity" range, no adjustment is made and interrogation passes to the next stand.
