Filed: 1970-09-30
Abstract: 1329610 Rod couplings JOSLYN MFG & SUPPLY CO 30 Sept 1970 [31 Dec 1969] 46536/70 Heading F2G [Also in Division H2] An end fitting coupled to a rod, e.g. of glass fibre, has an outer jacket with an inner surface that surrounds a portion of the rod and contains a material filling the space between surface and rod, the shape of the surface being so calculated that when the rod is loaded axially, the volume strain is uniform along the rod axis. Formulae are given for determining the shape of the inner surface of the jacket in dependence on the compressibility of the material filling the space between the jacket and the rod. As shown, a jacket 14 and a glass fibre rod 12 have a compressible substance, e.g. a zinc alloy collet 20, between them. The inner surface 15 of the jacket 14 is parabolic, approaching the parallel to the rod axis at the unloaded end of the rod. The parabolic surface 15 may be approximated by a series of straight line segments, Fig. 3 (not shown). In another form, the material filling the space between the inner jacket and the rod is a compressible epoxy resin, Fig. 4, 5 (not shown). The inner surface (36) of the jacket is of exponential form, being nearly parallel to the rod axis at the loaded end of the rod and flaring outwardly towards the unloaded end.

Abstract: 1450419 Phase sequence protection CANADIAN GENERAL ELECTRIC CO Ltd 9 Oct 1973 [11 Oct 1972] 47131/73 Heading H2K A phasing detector responsive to reversal of phase rotation or an open phase in a three phase A.C. system 10 has a transducer such as 13 for each phase (or between phases, see below) providing voltage outputs in phase with system waveforms for conversion by amplifiers 14, 15, 16 to square waveforms or lines A, B, C at 120 degrees spacing each fed to one limb of a Y circuit having a common point 34 with each limb including a current limiting resistor 35, 37, 39 and a transistor 36, 38, 40. The transistors are controlled through respective resistors 42, 44, 46 from other phase amplifiers arranged to be providing a positive bias at the moment that the Y limb becomes positive so that with the required phase rotation the transistors 36, 38, 40 conduct whenever positive square waves are provided and only low signals appear at point 48 through diodes 49, 50, 51 which the phase rotation is correct. On open circuit in one phase or incorrect phase rotation higher voltage signals appear at 48 due to the non-conductive state of a transistor and this signal, delayed by resistor, capacitor arrangement 55, 56, is fed at 53 to a voltage level detector 19 which can trip a circuit breaker 11. The current responsive transducers 13 may be replaced by inter-phase voltage transducers (Fig. 4, not shown). The voltage level detector 19 receives a power supply across points 54, 60 from an inhibitor 65 and on voltage rise at signal at 53 a transistor 66 conducts to switch on a further transistor 67 providing a tripping signal on line 20 and taking current I 2  which increases the current in a resistor 62 to reduce the voltage at V1 and turn the transistor 66 on harder. If the voltage to the inhibitor 69 fails at 75, 76 a Zener diode 71 ceases to conduct and the connection to 54 is interrupted and the voltage level detector 19 is then inoperative.

Abstract: 1330908 Stabilizing hydrofoil craft CANTIERE NAVALTECNICA SpA and V GUIDI 5 Oct 1970 [4 Oct 1969 31 Oct 1969] 47330/70 Heading B7A A hydrofoil stabilization system senses the movement of water transversely of a hydrofoil strut and adjusts the hydrodynamic trim of the strut to reduce to zero the horizontal component perpendicular to the chord of the strut of the water pressure acting on the strut. As illustrated, a hollow strut 2 is pivotable about a vertical axis I-I. The strut bends in response to forces F generated by transverse relative water movement so that a blade 12 acts through a servo-system to operate an hydraulic actuator 10. The actuator rotates the strut 2 into its minimum resistance position relative to the water. In a modification, Figs. 8 and 9 (not shown), the strut is fixed and the hydrodynamic trim of the strut is adjusted by operation of a trailing edge pivoted flap. In another modification (not shown), the strut is again fixed and its trim is adjusted by the action of air or water jets which deflect the boundary layer formed by the water around the strut to simulate the action of a pivoted flap. The stabilization system may be used alone or in combination with a system of flaps pivoted to the trailing edges of the hydrofoils themselves.

Patent GB-478820-A (GB)
Abstract: 478,820. Thermostatically controlling air - supply to combustion apparatus. MELLER, M. M., and WEISS, H., (trading as MELLER, K., [Firm of]). July 28, 1936, Nos. 20911 and 20912. Convention dates, Aug. 8, 1935 and June 18, 1936. [Class 126] [Also in Group XIII] A thermostat controlling the air-inlet regulator of a combustion apparatus is constantly heated by a source of heat and cooled by the combustion air passing in. The cooling effect is mainly dependent on the velocity of the air, so that the regulator setting responds quickly to changes in the rate of air supply. The fire itself may serve as. the source from which the thermostat is heated ; in this case, in order to maintain the air supply when the stove is first lit or is burning down, and the temperature is insufficient to cause the first thermostat to hold the regulator open, a second thermostat exposed only to the heating action of the fire is employed, which opens the same or a second air regulator as the temperature falls. Preferably, the two thermostats act differentially on the regulator in such a way as either to eliminate the effect of changes in fire temperature on the setting or, by an over-compensating effect of the second thermostat, to close the air inlet as the fire temperature increases. Figs. 1 and 2 show a thermostat 2, formed by a bimetallic strip, heated by radiation from the fire of a closed stove and cooled by the incoming combustion air, and controlling the air-regulating damper 5 by contact with an adjustable stop 3 on it. A second thermostat 7 heated by the fire is secured to the damper and contacts with an adjustable stop 8. When the fire is first lit or is burning out, the thermostat 7 holds the damper 5 open and the thermostat 2 is out of contact with the stop 3. as shown in Fig. 1. During normal operation, the thermostats bend as in Fig. 2, and the damper is controlled by the thermostat 2. Fig. 5 shows two bimetallic strips 13, 18 attached to the ends of a pivoted lever 14. The first, which is subjected to the cooling effect of the incoming air, bears against an adjustable stop 12 on the air damper 11, and the second, subjected only to the heating effect of the fire, bears against a stop 19. The arrangement acts in the same way as that shown in Figs. 1 and 2, and also compensates for changes in fire temperature by the differential action produced by the two thermostats. By over-compensation, produced for example by causing the fire to act unequally on the thermostats, or by making the thermostats of different sizes or the arms of the lever 14 of unequal lengths, an increase in fire temperature may be caused to reduce the opening of the damper and vice versa. In a modification, the two thermostats are mounted on parallel arms secured to a rotatablymounted shaft and extending to the same side of it.

Abstract: 1524056 Controlling burners PHILIPS GLOEILAMPENFABRIEKEN NV 24 Nov 1975 [27 Nov 1974] 48193/75 Heading F4T A burner 4 is supplied with gas through a manually-operated valve 13 in series with a solenoid valve 7 which is biased closed, which may be opened manually and which is maintained open when manual operation is ceased if an electric circuit, which is supplied with D.C., is completed by ionic flux generated by a flame in the burner, thereby energizing solenoid 10 of the valve 7. To start the burner knob 12 is depressed to open the valve 7 and is rotated to open tap 13. If the burner is ignited ionic flux between electrodes E1 and E2, constituted by the burner body 4 and a metal foil 16 insulated therefrom, causes current to flow in the coil 10 and maintains the valve 7 open even when the knob 12 is released; if the ionic flux ceases the coil 10 is de-energized and the valve 7 is closed by spring 11. The circuit, Fig. 2, which is supplied with D.C. either from the mains via a transformer and rectifier or from a battery, includes a first integrated circuit ICI for amplifying the current from the electrodes and rendering transistor TR1 conductive so that current flows in the coil SV (and in pilot bulb LS), and a second integrated circuit IC2 to render transistor TR2 conductive and prevent energization of the coil if the electrodes are inadvertently short-circuited. A capacitor C1 provides a delay in response of the circuit to allow ignition time.

Abstract: 1434253 Pressure exchangers; gas turbine plant BBC BROWN BOVERI & CO Ltd 23 Oct 1973 [25 Oct 1972] 49359/73 Headings F1G and F1N A pressure exchanger comprises a rotor 4 having a ring of open-ended cells 5 which are inclined with respect to the axis of rotation, the radially inner ends of the cells being arranged to co-operate with cold gas (e.g. air) inlet and outlet ports 7, 8 in an end housing (14) and the radially outer ends being arranged to co-operate with hot gas inlet and outlet ports 10, 11 in an end housing (13). Thus gases in the cells are subjected to centrifugal forces in addition to the pressure and dynamic forces. The cross-sectional area of the cells is kept constant by varying the radial dimensions of the cells between their ends to compensate for their inclination. The Specification explains how the centrifugal forces act to improve the type of thermal process in which the hot gas inlet and compressed cold gas outlet pressure are desired to be approximately equal while the expanded hot gas pressure is greater than the cold gas inlet pressure. Such a thermal process is desired where, as shown, the exchanger rotor is driven in unison with, or independently of, the shaft 3 connecting a gas turbine 2 and its compressor 1. Air from the compressor 1 after compression in the cells passes through a combustor 9 before being expanded in the cells and discharged to the turbine 2.
