Water is cooled in a cooling tower 1 firstly by natural draught in packing 4 and then by a forced draught induced through packing 8 by fans 14. As shown, water to be cooled enters the cooling tower 1 by a central pipe 2 and is distributed over an irrigation stack 4, the water being thus cooled by natural draught induced into the cooling tower through the upper part 16 of the air inlet 6. A decking 7, impermeable except for an annular peripheral region 10 divides the air inlet 6 into two parts. Within the peripheral region 10 are means for collecting water which has fallen through the upper irrigation stack 4 and distributing same over the cross-flow packing 8. Four fans (positioned within the casing 14) induce a draught through the lower part 9 of the air inlet 6 thus causing air to flow through the cross-flow packing 8 and up through the fans finally discharging in the main part of the cooling tower 1 augmenting the natural draught flow in this region. The cooled water is collected in a basin 5.

Abstract: 1284921 Measuring displacement electrically JUNGNER INSTRUMENT A B 4 Sept 1969 [13 Sept 1968] 43847/69 Heading G1N Apparatus for indicating the position of and/or measuring the linear displacement of a movable member comprises a pair of iron cores 1a, 1b of substantially rectangular cross-section having slots 3a, 3b for primary and secondary windings and teeth 2a, 2b confronting the toothed surface of an armature 4 of magnetic material and comprised in the movable member, the cores being spaced apart along the armature a distance equal to an odd number times half the tooth pitch of the armature teeth, the primary windings connected to a common A.C. input and the secondary windings connected to a circuit producing a combined output voltage having a phase shift relative to the input voltage representative of the position of the armature relative to the cores which phase shift varies through 360 electrical degrees when the armature is displaced one tooth pitch. In a first embodiment, Fig.3, secondary windings 6, 7 are arranged so that the induced secondary voltages are in phase but the sinusoidal variations in amplitude of the secondary voltages due to the armature displacement are 90 electrical degrees displaced one from the other. These secondary voltages are fed to a phase shift network of a resistor 9 and capacitor 9 producing a 90 degree phase shift between the voltages and providing the required combined output voltage representative of displacement. Alternatively in Fig.4 (not shown), respective primary windings (10, 11) are arranged to induce in the secondary windings, shown in Fig.4 (not shown) as a single winding (12), voltages of which the sinusoidal variations in amplitude due to armature displacement are displayed by 90 degrees, one relative to the other. The input voltage to the primary windings is fed through a phase shift network comprising two resistors (13, 14) and two capacitors (15, 16) arranged so that the voltages across the primary windings, and therefore the secondary voltages, will have a phase difference of 90 degrees. The secondary voltages are summed to form an output voltage having a phase shift, relative to the A.C. input, representative of armature displacement. In a second embodiment, Fig.5 (not shown) the cores are arranged on opposite sides of the armature with their toothed surfaces opposed and displaced half a tooth pitch and the armature (16) is a corrugated ribbon of which the tooth may be adjusted by stretching or compressing the ribbon.

Title: Digital synchronization system
IPC: H04N5/04
Filed: 1974-10-10
Abstract: 1474635 Television RCA CORPORATION 10 Oct 1974 [18 Oct 1973] 43926/74 Heading H4F In a television receiver the vertical deflection circuit is synchronized by an output pulse derived from a counter which counts pulses at twice the horizontal synch pulse rate the counter being reset by its own output pulse (which occurs when an appropriate number of counts has been effected) or by a pulse derived from a circuit which "scans" the received composite video signal for a pulse train having the same width as a vertical synchronizing pulse interval. As shown in Fig. 1, (which is concerned with a system using a horizontal scan rate of 15À75 kHz and a vertical scan rate of 60 Hz) horizontal frequency pulses derived from horizontal oscillator 27 are supplied via frequency doubler 100 to a divide-by-525 counter 110, the output pulses of which, i.e. each 525th pulse, resets the counter via a reset circuit 120 and after amplification and shaping in a circuit 130, synchronizes the operation of the vertical deflection circuit 41. Additionally, the composite synchronizing signal output of synch separator 26 is supplied to an arrangement comprising a low-pass filter 501, a peak detector 60 and a comparator 70 which arrangement operates to produce a pulse form vertical synch signals in the composite sync output of separator 26. This pulse is then "tested" to discover if it is of the same (known) width as a standard vertical synch pulse by sampling it in a serial-to-parallel converter 85 by means of the pulse output of frequency doubler 100 the sampled outputs, binary "1"s or "0"s being supplied directly and via two inverting inputs, to an AND gate 90. The latter produces an output only when the output of converter 85 is 01111110 which condition occurs only when the width of the sampled pulse is between 5 and 7 of the periods of the double horizontal frequency pulses, i.e. between 0À159 ms. and 0À222 ms. which width corresponds to the width of a standard vertical synch pulse. The output of gate 90 then acts to reset counter 110 via reset circuit 120. If, however, it should happen that a "noise" pulse occurs which has the same width as a standard vertical synch pulse so that counter 110 is reset earlier than it should be, no trigger pulse is produced for the vertical deflection circuit 41 which, as a result, "overscans". Such overscan is then detected by a circuit 140 which produces a pulse to trigger the deflection circuit via pulse shaper 130. Circuit details of the portion 150 are described with reference to Fig. 2 (not shown) and the operation is described with reference to waveform diagrams Fig. 3 (not shown).

Abstract: 1,191,545. Thyristor control circuits. BROWN, BOVERI & CO. Ltd. 18 Sept., 1968 [20 Sept., 1967], No. 44434/68. Heading H3T. [Also in Divisions G1 and H2] A thyristor 1 is controlled by a plurality of auxiliary thyristors 2 which are in turn controlled by respective light-sensitive devices such as photo-transistors 7, subject to a common light source. Each transistor 7 may have its emitter connected alternatively to a resistor (12, Fig. 4, not shown) connected to the anode of the associated thyristor 2, a Zener diode being connected between each such resistor (12) and the thyristor cathode. In a dark-sensitive embodiment (Fig. 3, not shown), a series chain of alternate transistors (7) and emitter resistors (10) is connected between the control electrode of main thyristor (1) and a resistance (5) connected to its anode, each transistor (7) and its resistor (10) being connected across the anode and cathode of a respective auxiliary thyristor (2) whose control electrode is connected to the emitter of its transistor through diodes (8, 9). Certain of the diodes (9) protect the transistors from reverse voltages and the others (8) provide a desirable voltage drop when the transistor (7) is in the low impedance state. In the absence of light, the transistors have a high impedance and their emitter potentials rise far enough to switch on the thyristors (2). In alternative embodiments (Fig. 1, not shown), a series chain of light-sensitive diodes (3) and normal or avalanche diodes (4) alternate with opposed polarities across the auxiliary thyristors (2), and the anodes, cathodes and control electrodes of the thyristors (2) are connected to intermediate points in the chain. Resistors (5, 6) connect the ends of the chain to the anode and cathode of the main thyristor (1). The diodes (4) reduce hole storage effects. Light-sensitive resistors (14, Fig. 5, not shown) may be substituted for the transistors of Fig. 2.
