Title: Heating and air conditioning system and air diffusers therefor
IPC: F24F1/00
Filed: 1958-06-11
Abstract: 890,233. Air conditioning systems. COTTS, L. C., and BRENNER, H. G. June 11, 1958 [Oct. 28, 1957], No. 18661/58. Class 137 An air diffuser for use in a forced air conditioning system comprises a chamber with an air outlet extending substantially full length of said chamber, an air inlet opening of a smaller longitudinal dimension than the chamber and connected to the forced air supply duct, and an electrical heating element mounted in the chamber above the air inlet. In a preferred embodiment (Fig. 2), the air outlet 36 is intermediate the height of the chamber 10 so that the part of the chamber above the outlet forms a conversion chamber to convert the velocity air pressure to static air pressure. The heating element 52 is removably mounted in a carrier directly above the air inlet 40, at least part of the heater being above the outlet 36, and the operation of the heater is controlled by a thermally responsive limit switch 58 set to open at about 170‹F. An air conditioning system incorporating the diffusers 10 in different parts or rooms of a building is shown in Fig. 1. The diffuser air inlets 40 are connected by ducts 80 containing dampers 82 to a main trunk 84 leading to a central air circulator 86 which is connected to several air return ducts 88 communicating with the spaces in which the diffusers 10 are located. A blower 90 provides a forced air circulation through return ducts 88, unit 86, trunks 84 and 80 to the diffusers 10 for discharge into the spaces to be conditioned. The unit 86 includes a filter 94, cooling coils 96, heating coils 98 either gas or oil fired or electrically heated, and, optionally, a humidifier. The coils 96 and 98 are controlled by suitable control elements and the blower 92 and the heating elements of the diffusers 10 are both controlled through electrical relays 112 and thermostat 114. Alternately, the heaters of individual diffusers may be separately controlled through thermostats 130. In another arrangement, either of the thermostats 114, 130 may also control the heating element 98 and the thermostat 114 may also control either or both of heater 98 and cooler 96. The blower may be arranged to operate whenever any room or zone requires heat or it may be operated continuously. Alternately, for the blower, a separate thermostat may be used which is responsive either to the air inside or outside the room or to the temperature difference.

Abstract: 1,177,139. Testing physical qualities electrically. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. April 24, 1967 [June 8, 1966], No.18684/67. Heading G1N. The temperature at which a carbon material has been graphitized is determined by taking samples from the material to be graphitized before it is graphitized and heating them to different temperatures within the graphitizing temperature range, and then, after the material has been graphitized, forming thermocouples between the graphitized material and individual ones of the heated samples and determining which of the individual samples shows the lowest or no difference in thermo-electric power with the graphitized material. Seventeen samples may cover a temperature range from 2, 200‹C. to 3, 000‹C. in 50 degree steps. Two samples cut in different crystallographic directions may be used for each temperature to provide a measure of the anisotropy of the graphitized material. As shown in Fig.3, a switch 27 enables different samples 3, 26 to be selected. The hot junctions, e.g. 24 are heated by a soldering iron 28.

Title: Improvements in zinc oxide
IPC: C01G9/02
Filed: 1939-06-29
Abstract: 530,858. Preparing zinc oxide. NON FERROUS METAL PRODUCTS, Ltd. June 29, 1939, No. 19022. Convention date, June 29, 1938. [Class 1 (iii)] Acicular zinc oxide is made by introducing a stream of substantially undiluted zinc vapour into a combustion zone of controlled temperature, burning the zinc vapour in the zone in a current of pre-heated air, and regulating the temperature of the combustion zone in the neighbourhood of 1225-1250‹C. in order to control twinning of the particles of zinc oxide produced. When the temperature of the combustion zone is maintained in excess of 1250‹C., the resulting zinc oxide particles are in the form of single acicular crystals, but when the temperature is mainained below 1225‹C., the particles obtained are in the form of complex twinned acicular crystals, such as threelings or fourlings. When the air is only moderately pre-heated, e.g. to 500‹C., the current should be slow and only in slight excess of that required to oxidize the zinc vapour, while if the air is intensely pre-heated, e.g. to 1000‹C., the current may be rapid and in great excess. In either case the air may be pre-heated by bringing it into countercurrent heat exchange relationship with the hot gases escaping from the combustion zone. An apparatus, suitable for carrying out the process, comprises a retort 10 for vaporizing metallic zinc, a duct 13 for zinc vapour, an air-preheating chamber 20, an annular heating jacket 15, a combustion chamber 19, a fan 23, and a zinc oxide collecting bag 25. Air enters the chamber 20 at 29. Pyrometers 27, 28, and a valve 26 for false air, are provided. Specification 406,560, [Group II], is referred to.

For this purpose, either the coil o is fed with intermittent current or it provides a slight polarity opposite to that impressed on the armature f by the poles of the magnet b. The magnet b may be an electro-magnet or a permanent magnet with windings.

Title: Improvements in separation of iron from its ores
IPC: C22B1/08
Filed: 1949-07-21
Abstract: In obtaining iron by treating a ferric acid to form ferric chloride and then reducing this with hydrogen, an excess of the reacting gas is supplied to each reaction vessel as part of a mixture of the two gases, the mixture leaving the chloridizing vessel flowing in a circulation system back <PICT:0677904/III/1> to the chloridizing vessel, and part at least of it, whilst so flowing, being enriched in hydrogen and then used as the mixture introduced into the reducing vessel.  As shown, iron ore, roasted at 300-500 DEG C to remove water or to decompose carbonates, is fed to the upper chamber 6 of a vessel 4 wherein it is partially chloridized at 100-200 DEG C with a 50-66 per cent HCE-50-34 per cent H2 mixture.  The steam produced, excess hydrochloric acid, hydrogen and a small amount of volatilized ferric chloride pass to cyclone 29 and condenser 36, wherein a dilute hydrochloric acid collects, the gas remaining passing to gasholder 38.  The partially chloridized ore passes to a lower chamber 7 wherein chloridization is completed at 250-400 DEG C.  Specifications 677,690 and 677,691 are referred to in connection with the chloridization. The gases are cooled to 150-200 DEG C in chamber 40, the distilled ferric chloride being deposited as almost dry crystals, and being passed therefrom to reduction chamber 42.  The gases pass to water-cooled condenser 44, wherein aqueous hydrochloric acid collects, the gases passing to a second gas holder 46 wherein they are enriched by hydrogen chloride obtained by treating with sulphuric acid, in vessel 69, the aqueous hydrochloric acid from condensers 36, 44.  The hydrochloric acid-rich gas from holder 46 is mixed at 1 with gases from the reduction of the ferric chloride, and is pumped to the chloridizing vessel 4, the part of the gas passing to the lower chamber 47 being preheated to about 300 DEG C in heat exchanger 5. The hydrogen-rich gas from holder 38 is pumped to vessel 42 wherein the ferric chloride is reduced to sponge iron, being joined at point 56 by hydrogen which is preheated by passage over the iron discharged in hopper 50.  The reduction vessel comprises an upper chamber 47 and lower 48, the gas passing via heat exchanger 54 to the former wherein reduction is effected at 300-500 DEG C and then via heat exchanger 60 to the latter wherein reduction is effected at 500-800 DEG C.  Heat exchanger 60 is supplied with gases from combustion chamber 63, which then pass to preheater 5.
