Abstract: 156,904. Bray, H. P., and Stenning, H. A. Oct. 14, 1919. Jointing tubes to headers.-In steam-superheating apparatus, steam-generators, and like structures, the seating-surfaces of the headers are inclined at an angle and wedge means are employed for forcing the tubes into contact with the headers. Wedge blocks 21, Fig. 6, are welded on to both ends 19, 20 of the tube element. The adjacent surfaces 22 of these blocks are provided with tapered grooves to accommodate a taper block 24, formed in one with a screw bolt 31 passing through a bolt-hole 32 in the header wall. The wedge blocks are machined with passages 25 which conform to the bore of the elements and terminate in the outer surfaces 26 of the blocks. A ridge 27 is provided on the outer surface of the wedge blocks, and by tightening the nut 33 the ridge is forced into a corresponding recess 28 in the header wall 29, a tight joint being made by a soft metal washer 30. A bridge-piece 34, Fig. 5, may be used to form an abutment for the nut 33 the wall of the header being cut away to form a space 35. According to a modified form, Fig. 12, the wedge blocks may be dispensed with and inclined lugs 40 welded on to the bent tubes and made to co-operate with the forked taper block 24. In a further modification, collars are welded on to the element ends, against which collars the taper block is adapted to work. Spherical seating surfaces may be provided on the pipe ends and headers to effect a metal-to-metal joint, and in order to obtain greater flexibility in the joint the surfaces of the lugs, collars, wedge blocks or taper blocks may be rounded as indicated by the dotted line 45, Fig. 12. Suitable forms of header for use with the joints are described. In one form, Figs. 1 and 4, the main superheated steam compartment 37 is arranged directly in front of the main saturated steam compartment 36. A number of subsidiary saturated and superheated steam compartments 36<a>, 37a, respectively, are connected to the main compartments, and are arranged below the plane of the latter, projecting forwardly. In a further form of header, Figs. 8 and 10, the subsidiary compartments 36a, 37<a> may be provided between the main compartments 36, 37. The subsidiary compartments are arranged alternately for saturated and superheated steam and are formed with an upper square portion and a lower angled portion, the latter projecting below the plane of the bottom wall of the main compartments. The dividing walls 39 are of sufficient thickness to permit boltholes 40 to be provided therein.

Title: Arrangement for regulating the supply of a direct current load supplied from a current transformer
IPC: H02P9/34
Filed: 1961-07-12
Abstract: 964,207. Automatic control of electric quantities. PRECISION MECANIQUE LABINAL. July 12,1961 [July 16, 1960], No. 25264/61. Heading G3R. [Also in Division H2] The supply to a load fed with rectified current by one or more current transformers is varied by short circuiting either the load or the load and the redtifier through which it is supplied at variable instants by means comprising at least one controllable rectifier. The load may be an alternator field or the exciting winding of a brake as described in Specification 853,977 for regulating the alternator. The controllable rectifier may be a thyratron or a semi-conductor controlled rectifier, and may be controlled either synchronously or asynchronously with the main current, by the current, voltage and/or frequency at the main load. In Fig. 1 the alternator 2 supplying a main load 4 has its field 1 fed through rectifier 5 from the secondary of transformer 3. Controlled rectifier 6 has its conduction controlled by the unit 7, which receives information about the main load voltage and current from the unit 9. For synchronous operation the winding 11 provides a signal at the appropriate frequency, but for asynchronous operation a generator 12 is used. Full wave rectification of the field current may be obtained (Fig. 3 not shown) using a centre tapped secondary winding, two rectifiers 5 and two controlled rectifiers 6. The Specification also describes a three phase alternator control system (Fig. 4 not shown) having a separate compound transformer for each phase, each secondary feeding the same load 1, through a separate rectifier 5, the load 1 and rectifiers 5 being shorted by controlled rectifiers 6 under the control of saturable reactors biased by direct current, the value of this current, and hence the point in the cycle at which the controllable rectifiers are triggered, being a function of the voltage or frequency at the main load. A further embodiment (Fig. 5) has three compound transformers supplying the load 1 through a full wave bridge rectifier, and a single controllable rectifier 6 switched by a further controllable rectifier 22 and commutating capacitor 21. A vibrator 24 under the control of unit 9 switches the controllable rectifiers alternately, so that the "on/off" ratio of controllable rectifier 6 is a function of the load voltage.

[Also in Division H5] The pivoted catch in the grill and switch locking arrangement described in Specification 699,960 is replaced by a sliding bolt. The grill is locked in the horizontal position of use by the bolt 17, Figs. 3 and 6 (not shown) being urged by a spring 21 to engage a slot 18 in a side member 19 of the grill. At the same time a detent 28, Fig. 5 (not shown), connected to the bolt is withdrawn from a slot 33 in a member 34 secured to the spindle 35 of a rotary switch 49 (Fig. 3), thus allowing the switch to be turned to the "on" position. With the power on, the detent 28 is prevented from lateral movement by the unslotted portion of member 34, and the bolt 17 cannot be withdrawn from the slot 18 until the switch is in the "off" position. A cover 51, Fig. 7 (not shown), over the grill is removable only when the grill is in other than the position of use when lateral movement of the bolt 17 is prevented by the unslotted portion of member 19 and the switch is therefore locked in the "off" position.
