Title: Improvements in and relating to apparatus for detecting variations in characteristic (e.g. flaws) in wire or wire-like bodies
IPC: G01N27/90
Filed: 1942-07-24
Abstract: 558,785. Magnetic tests; determining physical qualities. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). July 24, 1942, No. 10351. [Class 37] Apparatus for detecting flaws in wires and rods, such as tungsten wires or "Dumet" composite wires having a nickel-iron core and copper sheath, comprises an inductance 11 through which the wire 10 is passed and forms with condenser 12, 22 a work circuit connected to the plate 13 of a valve 14, the cathode 16 of which is connected via earth to the other side of the coil 11. A reference circuit comprising inductances 17 and condensers 19, 21 is connected between the cathode and grid 18 of the valve, the condenser 19 being shunted by a resistance 20 in a circuit 30, 34 including a neon lamp 27, and a pressbutton switch 28, connected across a variable resistance 29 across the supply. The h.t. side of the supply is connected to the plate 13 over a choke and milliammeter 24. In operation, a short section of the particular wire 10 is inserted and condenser 22 adjusted to compensate therefor, the condenser 21 being then adjusted firstly to produce maximum reading of meter 24 and then so that further adjustment cannot be effected without producing a marked drop in current in meter 24, thus ensuring that any flaw will stop the apparatus oscillating and cause such a drop, the apparatus being, if desired, purposely tested for this effect by scratching the wire. The lamp 27 is next tested by closing switch 28 with a perfect wire 10 in place, the lamp being then insufficiently energized, whereupon an imperfect wire :is inserted and the lamp should glow and remain glowing until 28 is again depressed. If the lamp fails to glow, the applied voltage should be adjusted by resistance 29. The feeding of the wire through the coil can then be begun, the lamp at once giving an indication of the fault and remaining glowing until steps are taken to locate the fault, by depressing 28 to put out the lamp and then reversing the feed until the lamp again glows. Specification 283,650, [Class 37], is referred to.

Title: Air conditioning system
IPC: F24F11/76
Filed: 1966-03-09
Abstract: 1,134,513. Heating and cooling buildings. A. I. McFARLAN. 9 March, 1966 [11 March, 1965], No. 10451/66. Headings F4U and F4V. In a system for air conditioning large buildings which usually require cooling of the interior during the whole of the year and heating or cooling of the periphery according to season, outside air is mixed with recirculated air and excess heat from the interior is used to heat the peripheral parts of the building during winter. Provision is made to supply a higher proportion of fresh air to conference rooms and 100% fresh air to the kitchens. Fig. 1 shows a chilled water circuit for cooling outside air and recirculated air in summer and to cool recirculated air in winter. Three refrigeration units 5, 6, 7 are connected in series and chilled water flows to an air treating unit 9 for recirculated air and to an air treating unit 10 for outside air. Chilled water is also supplied by a line 11 to units 12 in the peripheral part of the building. A valve 20 enables the water from unit 9 to return direct to a pump 16 or to be directed through unit 10 where the heat absorbed from the recirculating unit 9 is used to heat fresh air passing through the unit 10. A thermostatic valve 17 regulates the flow through unit 10 and a by-pass 18 back to the pump 16. In a modification (Figs. 2 and 3) a hot water system is added comprising a compressor (P), evaporator-water-chiller (E), condenser (C), and expansion valve (V). Thermostatically controlled valves (26, 27, 28) control the flow of cold and hot water or a mixture thereof and auxiliary heaters (29, 29a) are provided. Unused heat is dissipated by a cooling tower 31. The units 9, 10 and 12 may be controlled by adjusting the quantity of water supplied but preferably control is effected by modifying the temperature with a constant volume and rate of flow by use of valves (26, 27, 28). In a further modification (Fig. 4), for cool climates, an additional loop circuit (44) is provided and includes a second pump (32). Water returning from units 12 may be directed from the second pump (32) through the loop circuit when a first valve (44V) is open, and a second valve (45V) is closed, or may be directed to both pumps 16, (32) by opening the second valve (45V) and closing the first valve (44V). Air treating units in the periphery of the building may be air induction units (Fig. 9, not shown) or fan coil units (Fig. 10, not shown). Air outlets into the spaces to be controlled may be ceiling diffusers (Fig. 11, not shown) or pivoted vanes (Figs. 12 and 13, not shown) all of which are controlled by a thermal responsive device.
