Abstract: 1,255,731. Frequency and phase detectors. INTERNATIONAL STANDARD ELECTRIC CORP. 12 Feb., 1969 [12 March, 1968], No. 7656/69. Heading H3A. A frequency or phase detector includes a frequency selective network fed by a single source of input signals and provided with two output detecting circuits adapted to produce an output signal representing the difference between the magnitudes of the respective output signals from the network which includes a first essentially reactive two-terminal branch exhibiting a reactance with at least one reversal of sign at a predetermined frequency in series with a second two-terminal branch which is essentially resistive, these two branches being coupled to the detecting circuits. The arrangement is explained with reference to an arrangement in which current generator source i, Fig. 1, feeds a first low-impedance detector D1 via reactance circuit L, C, C/k<SP>4</SP>-l exhibiting both series and parallel resonance; the second, low impedance detector D2 is fed via resistor R, the output from one detector being subtracted from that of the other. In an embodiment of the invention, voltage-generator source e, Fig. 2, feeds the series/parallel resonant circuit and resistor R in series: high impedance detectors D1, D2 are shunted across the series/parallel resonant circuit and resistor R respectively. In a third embodiment, voltage-generator source e feeds three parallel-connected networks, comprising respectively capacitor Cl and resistor R1, resistor R2 and capacitor C2, and series resonant circuit Lo, Co in series with resistor Ro. High-impedance detectors D1, D2 are connected from the common point of series resonant circuit Lo, Co and resistor Ro and the common points of capacitor C1 and resistor R1 and of resistor R2 and capacitor C2, respectively. The Specification also describes the dual of the last circuit, employing a current generator and lowimpedance detectors (Fig. 4, not shown). In a practical embodiment of the arrangement shown in Fig. 2, the voltage sburee comprises a transistor T1, Fig. 5, acting as an emitter follower; it may be precluded by a limiter. Transistor T1 feeds a series circuit comprising the series/ parallel resonant circuit L, C, C/k<SP>4</SP>-1, in series with a resistance provided by resistors R9, R10. The first detector comprises transistor T<SP>1</SP>3 which is connected across the series/parallel resonant circuit via a buffer-amplifier comprising transistor T2. The second detector comprises transistor T3 which is connected via capacitor C5 across resistor R10.

A rotary switching device for coupling high frequency electromagnetic energy between a plurality of coaxial connectors 10-13 and a further single coaxial connector 14 comprises a switch driven through a shaft 24 by an electric motor 25, the switch comprising a conductive body 18 closed by a conductive member 19 to which are secured a plurality of arcuate contact sectors such as 33 engageable by a rotary brush 29 carried by an insulating support 26 attached to the shaft 24, which support also carries a conductive spindle 27 engageable by another brush 22 connected by means of the coaxial connector 14 to an instrument 15. The contact sectors are connected to the coaxial connectors 10-18 and thus by rotation of the brush 29 the antennas 1-4 may be sequentially connected to the receiver 15. The surfaces 34 of the body 19 to which the contact sectors are attached are planar, the sectors being secured, such as by a printing process, to dielectric members 35 which are secured to the body 19 by means of clamps 36. The contacting surfaces of the switch should be tarnish and wear resistant such as for example, rhodium or. planium irridium. The outer conductors of the coaxial lines are electrically connected to the bodies 18, 19 as appropriate, the inner connectors being connected to the brush 22 in the case of line 14 and to the contact sectors in the cases of links 10-18. In the latter cases the inner conductors are secured to conductive strips 39 which are then secured to the contact sectors the physical dimensions of the contact arrangement simulating a coaxial line. The length of the arcuate contact sectors is preferably made less the <SP>1</SP>/ 10 th of the wavelength of the highest frequency with which the switch deals and the spacing between the planar surfaces 34 and the contact sectors is made small compared with a quarter of such wavelength. Thus the electric field is a concentrated one and the spacing between each of the contact sectors may be made very small without serious coupling therebetween taking place.

In the gravity fed furnace shown, of the type disclosed in Specification 698,097, the primary air supply to the front wall 3 is controlled by an automatically-operated valve 19. Air from a blower 8 is conducted to spaces 11 and that behind a door 16 through a damper 10 which determines the amount to be supplied through conduits 12 and 14 to the secondary combustion space 15. Primary air may pass to the primary combustion space 2 through a valve-controlled opening 18 and the wall 3, through the fuel on the grate 6 by passing beneath the wall 3 and by flowing up through the grate 6 and the fuel thereon. The valve 19, formed with sealing flanges 21 and normally urged towards its closing position by its own weight, is controlled via a Bowden cable 22 by a thermostat or a servomotor controlled by the thermostat. At normal load, the valve 19 should be open. When the furnace is to operate at minimum load, the thermostat is set so that the valve 19 does not open until the water temperature in the water jackets or a steam boiler associated with the furnace has dropped below, e.g. 35‹ C. The thermostat may be responsive to room temperature or the operation of the valve may be dependent on steam pressure. The valve 19 may be spring-biased.
