Title: Improvements in the control of the temperature of superheated steam in water-tube boilers
IPC: F22G5/16
Filed: 1954-04-13
Abstract: 739,764. Steam superheaters. FOSTER WHEELER, Ltd. April 13, 1954 [April 13, 1953], No. 10851/54. Class 123 (3). In a water-tube boiler comprising a steam and water drum 10 to which are connected steamgenerating tubes 12 and downcomers 14 and a superheater having three series connected sections 16, 18, 20 arranged in a lateral gas pass 22, the saturated steam from drum 10 passes through pipes 28 to a heat-exchanger 30 wherein it is brought into indirect heat-exchange contact with water drawn from drum 10 through a pipe 32. Part of the steam condenses and the steam-water mixture leaves the heatexchanger through a nozzle 36 arranged in an enlargement 38 of a pipe 40 which connects the upper part of the water space of the heatexchanger to the first superheater section 16. The suction created by nozzle 36 reduces the pressure in the water space of the heat-exchanger and thus reduces the temperature of the water therein to below saturation temperature, part of the water evaporating into steam which passes through pipe 40 to join the steamcondensate mixture flow to the superheater. The flow of steam from the water space of the heat-exchanger is controlled by a valve 46 which is actuated in response to temperature variations in the superheater outlet header 24 by a regulator 48. A constant water level is maintained in the heat-exchanger by adjustment of a valve 44 in pipe 32, the valve being actuated by a float-controlled regulator 42. The arrangement provides means for maintaining the final steam temperature constant over the load range of the boiler. If, for example, this temperature rises with increasing load, the opening of valve 46 is increased and more steam passes from the water space of the heatexchanger causing the pressure therein to fall. The temperature of the water is thus reduced and more steam condenses, the water content of the mixture fed to the superheater consequently increases and the final steam temperature decreases to the required value.

Abstract: 1,003,777. Mechanical switches without quick action; retractive switches. GENERAL ELECTRIC CO. Ltd., and J. W. ZMARZTY. April 13, 1964 [March 19, 1963], No. 10853/63. Heading H2B. An electric switch arrangement comprises five wafer switches 1-5 (Fig. 1) the rotors of four, 2-5, of which are mounted on a square shaft 23 while the rotor 45 (Fig. 2) of switch 1 is rotatably mounted on an extension 24 of shaft 23. A pin 26 extends through a hole in extension 24 and seats in a groove 30 in an actuating member 11 whereby when an operating member 7 which can move between two normal rotational positions and is secured to member 11 is actuated switches 2-5 are operated. When the operating member 7 is in either of its two normal positions it can be pushed in whereby the pin 26 is unseated from the groove 30 and the other side of the groove 30 engages in one of two grooves 48 in rotor 45. The member 7 can then be rotated from each of its normal positions to a further position thus operating switch 1. Upon release of the member 7, springs 49 in a member 46, which is secured to the stator 47 of switch 1 and in which projections 51 on rotor 45 engage, return the switch 1 and operating member 7 to their normal positions and spring 52 causes member 7 to be pushed outwards. The switch arrangement is provided with a locating device 18 (Fig. 1) and an indicator lamp 8 (Fig. 2). Rotation of the operating member 7 further than between its two normal positions is prevented by a projection 31 on member 11 engaging in a groove 32 in a plate 16 and further than between one of its normal positions and the corresponding further position when the operating member is pushed in by engagement of the member 11 with the indicator lamp mounting plate 9. The switch arrangement may be used as a discrepancy key in a mimic diagram, such as is described in Specification 1,003,776.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/26
Filed: 1941-03-13
Abstract: 548,011. Shock absorbers. JOHNSON, E. W., and VANDERVELL PRODUCTS, Ltd. March 13, 1941, Nos. 11048 and 12977. Divided out of 541,179. [Class 108 (iii)] A rocking shaft 21 is damped by pistons 30, 31 rigidly connected together by a sleeve 32 and moving respectively in opposed cylinders 28, 29. The sleeve 32 is nearly filled by a stationary hollow metering rod 94 fixed by screw caps 40, 41 in the cylinder heads. Ports 95 allow the fluid, which mostly squeezes through the cylindrical gap between the rod and the sleeve 32, to by-pass this gap through the rod. Over the ports 95 at one end of the rod a spring-pressed collar 96 is slidably arranged, the spring normally forcing the collar against the end of the cap 40 to close' the ports. The contact wall of the collar 96 may be circularly grooved. Excess pressure in the cylinder 29 causes the fluid to enter a recess 100 in the collar 96 and press back the collar to allow passage of the fluid. By selection of a spring 97 of suitable strength, any desired degree of by-passing may be obtained, thus enabling a constant resistance to movement in one direction to be combined with any less resistance in the opposite direction. Several modifications are described, in some of which a control member in the form of a pin movable slidably in the bore of the rod 94; at the valve end thereof, shifts the collar over or off the ports. The control may be by Bowden wire, and the fluid pressure in this form has no tendency to close or open the valve. In other forms the pin itself determines the flow through the valve, in conjunction with an independent or connected outer collar, and one of the ports at the valve end may be permanently open. Specifications 541,179 and 541,201 are referred to.

Title: Process for the manufacture of zinc oxide from the metal or materials containing same
IPC: C22B19/34
Filed: 1931-04-15
Abstract: <PICT:0366808/III/1> In the production of zinc oxide from metallic zinc or materials containing it, the heat of formation of the zinc oxide produced by introducing the initial materials on to a fusion bed composed of reducing material which partially fills open-ended heated retorts and burning the zinc vapours as they issue from the retorts is utilized to assist the heating of the fusion bed.  As shown in the Figure, the initial material is continuously fed in small quantities at a time from hoppers 7 into retorts 1 which are partially filled by lumps of a porous reducing material 13, such as charcoal or coke.  Volatilized zinc admixed with carbon monoxide is burnt at the mouth of the retorts in a chamber 4b by air admitted through openings 8, and the zinc oxide passes by way of a flue 9 to condensing chambers 10.  The zinc burns with a short very hot flame, and the resultant heat is conducted downwards through the zinc vapours to the fusion bed 13.  The retorts are initially heated and maintained at a temperature of 1400 DEG  C. by means of a burner 11 opening into a combustion chamber 4c through which the retorts pass. At their lower ends the retorts open into a chamber 4 filled with the reducing material and provided with openings 5 for discharging residues.
