Title: Improvements in heat exchangers
IPC: F28F9/02
Filed: 1967-03-31
Abstract: A heat exchanger intended for use in a steam turbine installation, comprises an outer tubular casing through which extends a tube bundle consisting of a multiplicity of continuous metal tubes having an external diameter of less than 0À15 ins., said tubes being hermetically sealed at each end of the casing into a header plate positioned across the casing end section and also to spaced-apart partitions within the casing to form at least four separate chambers, whereby fluid introduced through suitable openings can be brought into heat exchange relationship with fluid in the tubes separately from the fluid introduced to the other chambers. In the form shown a collar 80 of polygonal outer section is placed around the requisite section of each tube 12 allowing the tubes to be contiguous with one another when clamped by a surrounding ring 84 (Figs. 2-4). Alternatively the tube ends are expanded to a hexagonal outline (90, Fig. 5) so that when the expanded sections are contiguous the tubes are spaced apart by the required distance. In another arrangement the header plate or partition comprises a stack of identically similar laminations (Fig. 6) apertured to receive the tubes. In another form (Fig. 8), the header or partition is produced by a matrix of particulate, woven or unwoven, stranded or fibrous material. In Figs. 9-13, (Figs. 10, 13, not shown) the header/partition is formed of a plurality of recessed or apertured members each forming a part of the area of the header/partition, e.g. strips (102), and the opposite faces of which include a plurality of spaced apart semicylindrical recesses 109, so that when the strips are stacked, corresponding recesses are aligned to define bores for receiving the ends of the tubes, the strip assembly defining a circular periphery for insertion in the casing. Similarly, instead of individual strips, the strips can be spirally wound (Fig. 11) so that the bores for receiving the tube ends are defined by the recesses in one layer and the contiguous surface of an adjacent layer. In another embodiment (Figs. 15-17) the tube ends are held tightly together in mutual contact by means of a suitable clamping arrangement, pressure then being exerted on the ends of the tubes to splay out the regions of the tubes between the clamping means, suitable spacers then being inserted. In all embodiments so described, each assembly is finally brazed, so that all the interstices become filled with the brazing material to form a solid and hermetically sealed assembly. The arrangement of the various chambers in the heat exchanger described (Figs. 1a, 1b, 1c).

Title: Device for on-load switching between taps of a multitap trans-former winding
IPC: H01F29/04
Filed: 1968-01-08
Abstract: An on-load transformer tap-changing arrangement comprises two static power switches I, II, each of which may be opened by a pulse at an input I 11 , II 11 and closed by a pulse at an input I 15 , II 15 , a selector switch 24, and a zero load current detector 20 which at each instant t 1 (Fig. 2) causes a pulse to be supplied to the opening input of one of the power switches, according to the state of switch 24, and each instant t 3 causes a pulse to be supplied to the closing input of the other power switch, tapchanging being initiated by the changing over of switch 24. Preferably the power switches I, II, comprise two thyristors connected in reverse parallel. At instants t 1 a pulse is generated at 21, is delayed a time # 1 by device 23 and is then received by switch 24. If switch 24 has not been operated since the last instant t 1 the pulse will be passed to the opening input of the power switch which is already open, and so no switching will take place. If switch 24 has been operated, however, the pulse will be received at the opening input of the power switch which has been conducting, and so this switch will be opened. The delay # 1 ensures that the current flow does not actually cease until time t 3 . At the next instant t 3 a pulse is generated at 22, is delayed a time # 2 by device 28 and is then received through one or other of the electronic switches 29, 30 and wave-shaping circuits 36, 37 at the input I 15 or II 15 of the power switch to be closed. The delay # 2 ensures that the other power switch has first been fully opened. Electronic switches 29, 30 are controlled by flip-flop 27 which is operated through 25, 26 by the pulses generated at 21. Switch 24 may follow-up the operation of a pre-selector connecting off-load the open power switch to the desired tapping.

Filed: 1968-02-05
Abstract: At least two signals modulating respective carriers f1, f2 are mechanically recorded in the same or different magnetic portions of a record groove for magnetic play-back. The signals are fed to a cutting stylus which either superimposes them to record hill-and-dale fashion (Fig. 2, not shown) or records them in respective side walls in the manner of a stereophonic record (Fig. 3, not shown). High and low frequencies may thereby be recorded in respective side walls which may subtend 90 degrees or less, e.g. 70 degrees. The signals are played back by a magnetic transducer 8 having magnetically hard guide layers 81, 83 enclosing a knife-edge core 82, the whole carrying a winding 10 feeding a filter 11 to separate the signals. The varying distance between the knife edge and groove provides the flux variation necessary for magnetic playback. The record may be magnetically soft and biased by a permanent magnet 9, or may have suitable remanence characteristics (not detailed). The record may be duplicated by pressing.

Patent ES-379971-A1 (ES)
Title: Device for producing direct voltage proportional to speed
IPC: H02K29/12
Filed: 1970-05-23
Abstract: Means for generating a unidirectional voltage related to a speed of rotation comprises a polyphase generator arranged to provide phase voltages having a flat-topped waveform configuration, and means for sequentially switching the flat topped portions of each waveform in turn to a common output. As shown a four-phase generator includes phase windings A, B, C, D and a permanent magnet rotor 2. Mounted on the rotor is a metal strip 3 extending over 180 degrees which serves as an exciting means for two inductive transmitters 4, 5 mounted at 45 degrees on either side of the field axis of the winding A. The transmitters consist of inductive proximity switches in oscillator circuits which become unbalanced and emit a signal when the metal strip is adjacent thereto. Signals x, y (which may be regarded as binary " 1 " signals) from the transmitters 4 and 5 are applied to inverting gates 9, 10. The outputs from these gates x, y will be "0" when the signals x, y are binary " 1 " and will be binary " 1 " when x and y are zero. Consider a clockwise rotation of the rotor. For revolution the strip 3 will be adjacent transmitter 4 only (signal x) for the next revolution it will be adjacent 4 and 5 (signal x and signal y) for the next revolution it will be adjacent 5 only (signal y) and for the last quarter it will be adjacent neither (no signals). The outputs of the inverter gates 9, 10 in corresponding periods are #y, zero, #x, and #x+#y. Four AND gates 11, 12, 13, 14, are arranged to respond to the combinations x+y, x+y, x+y y and x+y respectively and actuate electronic switches 19, 20, 21, 22 to connect phase windings A, B, C, D to a common terminal (23 or 25) for successive quarter cycles. The generator design involves a flux of triangular waveform which provides a phase voltage waveform having a flat portion extending over more than 90 degrees, so that the switching arrangement results in a unidirectional voltage whose amplitude is related to the speed of rotation. A modified switching arrangement is envisaged for a generator where the windings are connected in series opposition (Fig. 3, not shown). A further modification (Fig. 4, not shown) discloses an arrangement of a plurality of conductive strips and transmitters for use with a 16 phase generator.
