Title: Improvements relating to Hair Dryers
Inventor: MASON ARTHUR WILLIAM
IPC: A45D20/44
Filed: 1967-08-11
Abstract: 1,186,037. Hair dryers. A. W. MASON. 17 Sept., 1968 [11 Aug., 1967], No. 36953/67. Heading A5R. A hair dryer capable of feeding air to adjacent identical or slave units comprises an electric motor 6 driving fans 7 which move air over heating elements 8 to apertures in a rotatable valve member 10 which has two transfer ducts 13 extending laterally therefrom and an outlet duct 12 leading to a hood 4 associated with the unit. The valve member 10 has a fixed cylindrical wall 9 with five equally spaced apertures connecting with ducts. Three chordal walls 11 define four chordal paths for airflow, and the member 10 is rotatable about an horizontal axis on actuation of a knob 14 on the upper surface of the unit which operates a worm 16 driving a valve member spindle to any of four different flow paths, Fig. 4 (not shown). Five different working modes, Fig. 3 (not shown) are obtained using these four flow paths with one, both or neither of the heaters brought into operation, as required, by switches operated by cams 17 on the valve member spindle. In mode (I), Fig. 3 (not shown) only one heater is in operation, which supplies hot air to the unit's own hood. Flap valves 18, Fig. 1, in the transfer duct 13 are controlled by links 20 from a groove 19 in valve member 10 forming a face cam such that when the dryer is operating in mode (I) the valve is closed preventing the flow of cold air to an adjacent unit. In modes (II) and (II]) both heaters are switched on and hot air is supplied to the unit's own hood and to an adjacent unit on the right and left respectively. In modes (IV). and (V) both heaters and fans are switched off and the unit receives hot air from units on the right and left respectively. A dial 14a below the knob 14 is driven through a reduction gear by the knob such that its angular position always corresponds to that of the valve member 10, and it is marked to show the mode of operation of the dryer. The hood 4 is mounted on a piller 3 which can be raised or lowered by means of a rack and pinion drive under the control of knob 5 or by a wire &c. passing over a drum or pulley. The two heaters have their own on/off and progressive control knobs 21 in series with switches actuated by cams 17 such that the current cannot reach the heaters unless the fan motor is on and valve member 10 is in the appropriate position. Indicator lights 21 are illuminated when the heaters are on, and further lights indicate when the respective heater is supplying one of the transfer ducts. In a modification it is arranged that in one of each of the (IV) and (V) positions of dial 14a the fan and one appropriate heater is on so that, while receiving hot air from a unit on one side, the unit is also supplying hot air to an adjacent unit on the other side.

Title: Improvements in refractory metal articles
Inventor: LLEWELYN GEIRIONYDD
IPC: C23C10/56
Filed: 1961-10-17
Abstract: An article of refractory metal containing at least 50% niobium by weight has a modified surface layer containing chromium, silicon and aluminium alloyed with the body metal formed by heating said article in contact with a powdery mixture comprising Cr, Si and Al in powder form in admixture with a non-reactive dispersant and an activating substance selected from NH4Br, NH4Cl, NH4I, the time and temperature of the heating being sufficient to form a modified surface at least 0.001 inch thick containing Cr, Si and Al alloyed with the niobium-base substrate.  The powdery mixture is permeated with inert gas throughout the heating, said gas being argon or helium and not nitrogen or hydrogen.  The invention is designed to provide high temperature surface protection to gas turbine blades fabricated from niobium and niobium-base alloys.  The reactive content of the powdery mixture comprises 20-75% Cr, 20-75% Si and 3-25% Al; the particle size being up to 300 mesh.  The non-reactive dispersant is preferably alumina, of particle size 100-300 mesh, present in a quantity by weight varying from 0.5-1.5 times the weight of the reactive content of the powdery mixture.  The activating substance is preferably NH4Cl, present by weight from 0.5-2.0% of the total weight of the powder mixture, e.g. 1.5%.  Heating may be conducted in one or two stages.  For heating in two stages the temperature is lower during the first stage than during the second stage.  For heating in one stage the reactive content of the powdery mixture preferably has by weight 40-70% Cr, 20-50% Si, 3-25% Al.  For heating in two stages the reactive content of the powdery mixture may be relatively rich in Cr during the first stage of heating and relatively rich in Si during the second stage or it may have the same composition for both stages, e.g. 45% Cr, 45% Si, 10% Al.  In an example sheet metal alloy of 10% Ti, 10% W and the remainder Nb was treated.  Treatment temperatures range from 1300-1400 DEG C., preferably 1350 DEG C., and when two-stage heating is applied the first stage is at 1180 DEG C.  In the presence of an excess of activating substance the thickness of the modified surface is dependent upon the temperature and duration of heating.  Oxidation resistance may be further enhanced by applying a surface glazing to the modified surface.  The composition of the reactive content of the powdery mixture for a two-stage treatment was, for the first stage, 70% Cr, 25% Si and 5% Al, and, for the second stage, 25% Cr, 70% Si and 5% Al.  A further alloy substrate mentioned analyses 15% W, 5% Mo, 1% Zr and the balance Nb.

Filed: 1975-09-15
Abstract: 1510719 Absorption spectrometry PERKIN-ELMER CORP 15 Sept 1975 [16 Sept 1974] 37814/75 Heading G1A Absorption spectrometry apparatus comprises means for: directing a beam of mono-chromatic radiation of predetermined absorption-line wavelength, and a pulsed non-monochromatic beam including the predetermined wavelength, along a common path; splitting the combined beam into sample and reference beams directed through respective regions; chopping the beams prior to their entry into the respective regions; redirecting the sample and reference beams, after they leave the respective regions, along a common path, and isolating therefrom a wavelength band including the predetermined wavelength; and measuring the intensity of the isolated wavelength band at periods dependent upon the pulsing and chopping periods. Continuous line-spectral light from e.g. a hollow-cathode or electrodeless-discharge lamp 12 Fig. 1, and pulsed non-mono-chromatic light from e.g. a deuterium lamp 26, are in one operation of a semi-reflective beam-splitter 18 combined together and split into sample and reference beams S, R, each being modulated by a chopper 60 before being focused in respective sample and reference regions and then redirected in a second splitter 36 to pass through a mono-chromator 48 having a pass-band centred on the line wavelength of the source 12. A logic circuit 58, controlling the speed of the chopper 60 and the pulse rate of the lamp 26 according to a program illustrated in Fig. 2, synchronously sorts the signals from a photo-multiplier 56 sensing the mono-chromator 48 output. In Fig. 2, 1, Io, represent the intensities of received light due to the map 12 via the sample and reference paths respectively; and (D 2 ) S  and (D 2 ) R  the intensities due to the lamp 26 via the sample and reference paths respectively. Signal processing means in the logic circuit 58 manipulate the sorted signals to determine the spectral absorbance of an atom of interest in the sample region 20, eliminating errors due to background effects, e.g. molecular absorbance or scatter, which affect the line wavelength and adjacent wavelengths alike. The sample may be atomized in a flame, in which event a steady component due to flame emission may be eliminated by subtraction.
