Title: Regulating superheat in steam generators
IPC: F22B35/10
Filed: 1972-01-05
Abstract: 1309717 Regulating superheat in steam generators SULZER BROS Ltd 5 Jan 1972 [14 Jan 1971] 489/72 Heading F4A A method of regulating superheat is employed in steam generators of the kind having a forced flow through an evaporator with superimposed water circulation effected by at least one circulating pump, and comprises injecting water from the output of the circulating pump(s) into superheated steam. In the embodiment shown feed pump 1 delivers water through preheater 2 to a mixer 3 which also receives water from separator 10 and water from the mixer 3 is circulated by circulating pump 4 through evaporator 8 to the separator. Steam passes to super heaters 13, 14, 15 and water injectors 17, 18 are provided between them which receive water from the output of circulating pump 4 via line 26. A further line 29 from the output of the feed pump 1 can be connected to the injectors via valves 19, 20 when pump 4 is inoperative, as it is when the evaporator operates at full load, the amount of water injected being controlled by valves 21, 24 operated by temperature sensing elements 23, 25. In a further embodiment (Fig. 2, not shown) the feed pump (1) delivers water to either the steam or water space of a separator drum (32) from which water is fed to the circulating pump (4). Water from the output of each pump passes through a one-way valve to a common injector line and the valve system allows water to pass from the feed pump only when the circulating pump is inoperative. Additional regulating means such as tiltable burners or flue gas recirculation may be employed. The term evaporator includes the equivalent components used in supercritical steam generators.

Title: Improvements in or relating to electric chokes, transformers or the like having a variable reluctance
IPC: H01F29/10
Filed: 1948-01-10
Abstract: 646,464. Transformers and inductances. MULLER, H. Jan. 10, 1948, No. 811. [Class 38 (ii)] A variable reluctance electromagnetic aerial, e.g. a choke transformer, relay has a shell-type core in the frame of which a gap is provided in the form of a neck to embrace a movable central limb so as to provide a surface area for the air gap substantially larger than the crosssectional area of the core frame. Fig. 1 shows a choke core, one portion of which consists of two sets of laminations a<SP>1</SP>, a<SP>2</SP> and a centre movable limb c which slides through the neck formed by the ends of the laminations a<SP>1</SP>, a<SP>2</SP>. A fixed insulating tube f surrounds the limb c and carries winding g. By sliding the limb c, the reluctance of the air gap between its inner end and the fixed portion of the core may be varied. When the limb c is fully in, the length of the said air gap is determined by the thickness of the interposed insulator e and, in this position, the core has the same characteristics as that of a shell-type transformer. By providing a longitudinal cut in the limb c and an air gap b between the laminations a<SP>1</SP> and a<SP>2</SP>, the eddy currents are reduced. In a modification, instead of the winding being on the centre limb c, a pair of windings g<SP>1</SP> are mounted on the sides of the core part formed of laminations a<SP>1</SP>, a<SP>2</SP> so that as the centre limb c is withdrawn the fluxes of these two windings come into opposition progressively. In further modifications, the neck portion formed by the ends of the laminations a<SP>1</SP>, a<SP>2</SP> is turned inwardly or is in part inwardly and in part extended outwardly. In a further modification, the winding on the central limb c may be conical in shape. In a still further modification, a common central limb is arranged to slide in two identical core parts. The limb carries two windings, one at each end of the said limb. These windings are in series with their free ends connected across the supply lines and across one of the windings is connected a load circuit. The Provisional Specification also describes a modification in which the winding on the central limb may be in the form of a winding wider at each end than at the middle. Specification 600,842 is referred to in the Provisional Specification.

Title: Method and apparatus to recognise the position of the rotor of a stepping motor
Inventor: GETE HENRI
IPC: H02P6/185
Filed: 1992-05-07
Abstract: The method according to the invention is applicable to motors comprising a magnetized rotor having two diametrically opposed poles, a stator making up a magnetic circuit having saturable constricted portions and a coil coupled magnetically to the stator. The method consists in applying to the coil an electric pulse, in measuring a control current (I'01, I'02) generated within the coil by the electric pulse at the end of a control time interval (t'o-ti) and in comparing the control current with a reference current (Ir), the sign of this comparison being representative of the position of the rotor. In order to take into account the variations in the characteristics of the motor with time, the control time interval (t'o-t'i) is readjusted periodically by means of first and second electric pulses of a learning signal applied to the coil. The first pulse of this signal generates within the coil a first current (I1) which reaches the reference current (Ir) after a first time interval (ta-ti). The second pulse generates a second current (I2) which reaches the reference current (Ir) after a second time interval (tb-ti). The mean value of the first and second time intervals is then taken as the value of the control time interval (t'o-ti). The device for carrying out this method enables the position of the rotor to be identified under optimal conditions and can be used with advantage in timepieces.
