Class 75(1) In a liquid fuel burner fuel is dispersed in primary combustion air to form a combustible mixture and the ignited mixture is directed through a flame orifice on to a screen, provided with secondary air ducting, placed in front of the flame orifice to deflect the flame laterally and rearwardly. In the arrangement shown in Fig. 1 fuel supplied through a pipe 8 to a vapour-burner 1, 2, is vaporized and burnt with primary air supplied through a duct 7 and apertures 3. The burner 1, 2 is enclosed in a jacket 5 provided with inturned upper ends which extend in air tight connection past the upper edge of the burner 1, 2. Secondary air is supplied through the pipe 7, pipe 4 and a pipe 9 into a screen 10 arranged above and extending laterally and rearwardly over the burner 1, 2. The secondary air passes through an outwardly extending duct 12 and an inwardly extending duct 13 in the screen 10 and discharges through a central opening 14, around the pipe 9, into the burner 1, 2 to deflect the flame laterally and rearwardly. A throttle valve 15 provided on the screen 10 controls the secondary air supply. In the embodiment shown in Fig. 2 a pressure atomizing unit 21 having an upwardly directed flame orifice 22 and an atomizing nozzle 23 replaces the vapour burner. The screen 10 is similar to that shown with reference to Fig. 1 except that the secondary air pipe 9 is at the top of the screen 10 and a boss 24 with suitably inclined surfaces is placed in front of the flame orifice 22. The burner may be disposed on a horizontal axis or at any oblique angle.

Title: Improvements in electroluminescent lamps
IPC: H05B33/14
Filed: 1953-12-07
Abstract: 778,067. Electroluminescent materials. SYLVANIA ELECTRIC PRODUCTS, Inc. Dec. 7, 1953 [Dec. 5, 1952], No. 34023/53. Class 39(1). The phosphor of an electroluminescent, lamp comprises a matrix of one or more of the compounds zinc or cadmium sulphide, selenide or telluride, activated by copper and magnesium and incorporating up to 4 mols of magnesium oxide per mol of said compounds. The amount of magnesium may be as small as 0À001 atoms per molecule of the one or more zinc and cadmium compounds. The copper content range is 0À010-0À30 per cent and manganese (0À005-1À75 per cent) and lead (0À003-0À0001 per cent) may be included. Washing the phosphor in acid solution is stated to increase the brightness and the blue/yellow ratio of the luminescence. The presence of a relatively large quantity of magnesium oxide in the material is not harmful, due probably to its low conductivity. In one example zinc sulphide, zinc oxide, lead carbonate, basic copper carbonate and magnesium carbonate are blended and fired at 1750‹F., the fired material being washed in acetic acid and deionized water. Zinc oxide /sulphur may be used instead of zinc sulphide, ammonium sulphate and chloride also being added. The phosphor mixed with castor oil is formed as a layer between a metal plate and a transparent conductive layer on a glass sheet.

A pressure-reducing device for use in vehicle hydraulic brake systems comprises a piston mounted for sliding movement in a cylinder 1 and having a head 6 which co-operates with an annular packing 7 of resilient material through which the piston-rod 5 passes with radial clearance, an annular collar 8 mounted for sliding movement in the cylinder in proximity to the annular piston head packing and serving as a stop engaged by one end of a spring 9 surrounding the rod 5 and bearing at its other end against an annular seal 11 which seals the passage of the piston-rod through an end wall 1a of the cylinder. The collar has on the external surface thereof remote from the packing 7 a cylindrical portion 8a the external diameter of which is less than the internal diameter of the cylinder and which extends past an inlet port 12 for connection to a master cylinder. Due to the position of the port 12 in correspondence with the annular passage 13, fluid entering the port creates a vortex flow in the passage and which flow forms a liquid emulsion that is expelled through the bore 4.

Title: Method for minimising effect of intermodulation noise in fm communication systems
IPC: H04B14/00
Filed: 1965-08-13
Abstract: 1,095,634. Radio signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Aug. 13, 1965 [Aug. 18, 1964], No. 34717/65. Heading H4L. In a frequency modulation radio communication system the frequency deviation of a local transmitter is automatically adjusted in response to control signals sent from the remote end until the intermodulation noise and the thermal noise components received at that remote end are substantially of the same amplitude. As described, the input to a modulator 12 of a local station transmitter 14 comprises intelligence signals, and a pilot signal of frequency f 1  from an oscillator 10. At the remote station, the output of a receiver 22 is separated by filters 24 into (a) intelligence signals, (b) signals of frequency f 1 , on a lead 24<SP>1</SP>, and (c) signals of frequency nf 1 , which are proportional to the intermodulation noise, plus a sample of the overall noise. The part output (c) is amplified, and is separated by filters 26, 28 into nf 1  and noise components, which are respectively rectified by detectors 27, 29. The nf 1  is normalized before detection by a gain control 25, which is responsive to the # 1  signals on the lead 24<SP>1</SP>. The detector outputs are compared in a resistor network R 1 , R 1 , R 2 , R 2  (R 2  >> R 1 ) and the resultant signal operates a voltage controlled oscillator 23, whose output is applied, together with intelligence signals, to the modulator 21 of a transmitter 19. These signals are received by a receiver 17 at the local station and the component due to the voltage controlled oscillator 23 is extracted by filters 15, rectified by a detector 13, and applied to a deviation control 11. The frequency deviation of the modulator 12 is thereby altered by the control 11 until there is a substantial equality of the intermodulation and thermal noise components at the remote station. Similar equipment may be provided in respect of signals sent from the remote transmitter 19 to the local receiver 17.
