Abstract: 1,225,093. 093. Modifying metallic surfaces; nickel base alloys. R. C. A. CORPORATION. Feb. 11, 1969 [March 22, 1968], No. 7368/69. Headings C7A, C7U. [Also in Division H1] In the preparation of a cathode comprising a predominantly nickel substrate with a metal oxide coating thereon, the uncoated substrate is cleaned by heating, e.g. at 800 C. to 1200 C., in an atmosphere of which the active consituents are hydrogen and water vapour and having a dew-point in the range of -40 C. to 0 C., and the substrate is then coated with a material which produces the oxide coating upon subsequent heating. Preferably the atmosphere called "damp" hydrogen, has a dew-point between -35C. and -20 C. and the substrate is heated to between 1000 C. and 1100 C., referred to as "damp-firing", in, for example, a continuous or periodic furnace. Part of the hydrogen of the atmosphere may be replaced by a neutral gas such as argon, neon or nitrogen, and in one example dissociated ammonia with 25 volume per cent of nitrogen, replaces the hydrogen. The substrate may contain, apart from nickel, up to 10À5 weight per cent of tungsten, 0À005 to 0À3 weight per cent of magnesium and 0À005 to 0À3 weight per cent silicon, and may also contain very small (specified amounts of Al, C, Co, Cu, Fe, S and Mn or Ti. In one example given, a cylindrical, cup-shaped nickel alloy substrate is heated at 1000 C. -1100 C. for seven minutes in a continuous furnace with an atmosphere having a dew-point of -25 C., and after cooling is sprayed with Ba, Ca and Sr carbonate composition to give a coating of 3À5 mil. thickness and 0À35 milligram weight. Preliminary cleaning of the substrate by degreasing and washing may also be made.

Abstract: 1,264,998. Road signals for controlling traffic. OMRON TATEISI ELECTRONICS CO. 25 Feb., 1969 [8 March, 1968; 12 March, 1968], No. 9973/69. Heading G4Q. In a system for controlling traffic signals at a street intersection, the time during which the traffic signal 6, 7 is to be controlled is divided into a plurality of successive periods of time T, a circuit 11 coupled to a vehicle detector (4, Fig. 4, not shown) on one of the streets produces a first signal indicative of the traffic information quantity, a memory 12 receives and stores the first signal during at least every other of the periods of time, a circuit 13 produces at the end of the every other period a second signal representative of a preselected level of the information quantity measured and stored during this period A and a circuit 14 selects one of a plurality of predetermined control patterns for the traffic signals in accordance with the level of the information quantity represented by the second signal so that the traffic signals are controlled with the selected control pattern for the immediately succeeding period of time B. Information from a traffic detector (4) is obtained in traffic information provider 11 and is continuously memorized in information memorizer 12. After predetermined periods of time T the information memory 12 is reset by period of time setting device 17 and the information previously stored such as in period A is passed to an information calculator 13. The information obtained in calculator 13 is then used to select the necessary control pattern in 14 for control of the traffic signals 6, 7 during the immediately succeeding period B. The information calculator 13 may use the highest or 90% of the greatest information quantity stored in the memory, e.g. the greatest P is used in Fig. 2. The time setting device 17 may be synchronized to the cycle time of the signal controller 15. The two periods of time for example may be arranged to start with the green and red cycle respectively (Fig. 3, not shown). The traffic information quantity obtained in the green period (V) is then memorized and used to control the signals during the immediately succeeding red period (W). The traffic information quantity may be the greatest, or the last value measured in the preceding period. Alternatively the period of time during which the information is obtained may be extended a time (T1) after the end of the green period (V) before the information is used to control the remaining part of the immediately succeeding red period. The information stored is then further held a time (T2) and also used to control part of the initial portion of the next succeeding green period. All intermediate periods, that is between control by the held information, are controlled by the traffic conditions actually occurring in these intermediate periods. The specification indicates that the traffic information may take the form of traffic volume, density occupancy, vehicle speed or traffic stagnation on the street and that known vehicle detectors are electromagnetic, supersonic, photo-electric or radar type.

Abstract: 1289789 Turbomachine blades GENERAL MOTORS CORP 17 June 1971 [17 June 1970] 28559/71 Heading FIT A cooled blade or vane for use in a hightemperature turbomachine, e.g. a gas turbine, comprises a rigid hollow core 14 and a facing 15 bonded to and covering the core, the core having distributed perforations 28 to conduct cooling air from within the core to the facing. The facing is shown in Fig. 3 as comprising two layers 16, 18 but it may comprise only one layer or alternatively more than two layers. The facing inner surface abuts the core outer surface and one of these surfaces is relieved so as to provide passages between and generally parallel to the surfaces for the flow of cooling air. As shown, the relief is in the form of an array of bosses 30 on the outer surface of the core 14, with a similar array of bosses 31 on the outer surface of the inner layer 18 of the facing 15. The outer layer 16 of the facing 15 has an array of pores 34 through the layer, and the inner layer 18 an array of pores 32, the pores 34 being out of register with the pores 32, which in turn are out of register with the perforations 28. The interior of the core 14 is connected via the perforations 28, the passages between the bosses 30, 31, and the pores 32, 34 to the exterior of the facing for transpiration cooling. In an alternative construction, Fig. 5 (not shown), the core outer surfaces is left smooth and the bosses are formed on the inner surface of the two layers of the facing. The core 14 is of a cast super alloy having greater strength than the facing at high temperature and the facing 15 is of a ductile wrought super alloy sheet having greater resistance to corrosive attack by high temperature gases than the core. Nickel base super alloys are suitable for both the core 14 and the facing 15. At the trailing edge 10 of the blade or vane, the air passage 19 defined by the hollow core 14 discharges through a narrow slot 26 extending spanwise to provide convection cooling. Adjacent the trailing edge 10, the two faces of the core 14 are close together and joined by unitary cast pins or spaces 27. To provide for cooling of the leading edge, the inner layer 18 is removed locally to provide a series of chordwise channels adjacent the leading edge and over the forward portion of the concave face 11 to which cooling air is delivered from the passage 19 through a row of nozzles 38.

Abstract: 1297923 Cross correlation MULLARD Ltd 28 Nov 1969 58371/69 Heading G1U [Also in Divisions H1 and H4] In an arrangement for obtaining a signal which is a function of the cross correlation of first and second signals, photo images representing the two signals are applied respectively to non-overlapping areas 7, 8 of a body 1 of Piezo-electric photoconductive material to set up corresponding conductive patterns therein and an electrical signal is applied to the first area across electrodes 2, 3 to cause a mechanical stress pattern signal to be propagated towards the second area across which a signal representing the running cross correlation of the two signals is produced between electrodes 3, 4 as the stress pattern passes through the second conducting pattern. The photo images are produced by cathode ray tubes 13, 14 which scan the areas whilst being intensity modulated by the respective signals, cylindrical lenses 11, 12 converting the cathode ray tube spots into lines 9 which extend across the width of the areas. The cross correlation is obtained by integrating the running correlation signal in unit 33. The arrangement can be used in a pulse radar system, Fig.4 for automatically determining radar range. An output pulse for transmitter 70 is applied via T/R switch 71 to the aerial, and also via a demodulator circuit 80 and delay 81 to the cathode of cathode ray tube 14. The transmitter also issues a timing pulse to timing and range indicator unit 90 which in response issues a strobe pulse to open receive gate 77 and pulses to trigger the CRT scan units 17, 18. The received pulse is applied via gate 77 to the cathode of CRT 13. On completion of the scans, unit 90 triggers pulse generator 24 to apply a pulse signal across the first area 7 of the element 1 and at the same time triggers a ramp signal generator, Fig.3 (not shown). When the running correlation signal reaches a maximum i.e. when the stress pattern due to the received signal coincides with the conducting pattern of the transmit signal a capacitor storing the ramp signal is disconnected from the ramp generator source and the capacitor signal is compared with a fixed signal which would be generated by the ramp circuit if the transmit and receive signals occurred at the same time. The comparison provides a difference signal with sign which is used via unit 90 to modify the transmit pulse delay 81 or used to provide via unit 90 an output indicative of target range.
