Title: Improvements in electric imitation solid-fuel fires
IPC: F24C7/00
Filed: 1933-05-18
Abstract: 416,358. Imitation fires. BATES, S. W., Highclere, Roils Head Road, Halifax, Yorkshire. May 18, 1933, No. 14353. [Class 126.] A flicker effect is produced in an imitation solid-fuel fire by one or more electric bulbs of the type giving light of a flickering nature without the aid of external mechanical or electrical devices, for example a bulb charged with neon gas or a gas mixture and constructed so that the luminous glow area moves round the interior of the bulb. The light may be rendered the desired colour by the use of an appropriate gas or gas mixture, or by colouring the bulb. Fig. 1 shows an imitation fire with the fuel partly cut away to show the flicker lamp 4 and an ordinary lamp 5, which are concealed behind it. The fuel is translucent and is provided with apertures 6 and may be further illuminated from the front by an external flicker lamp, screened from view for example by a kerb. The apertures in the fuel may be arranged so that the moving luminous area is visible through them. In another form of fire a reflector is arranged behind the flicker lamp, a coloured translucent panel is provided in the base, the back of the fire above the fuel forms a reflector, and a heating element is arranged beneath the canopy. Fig. 4 illustrates a simple form of imitation fire not provided with imitation fuel, comprising a reflector 1 with a heating element 2 and one or more flicker lamps 3 secured by the upturned shield portion 4.

Abstract: 1,104,545. Frequency measurement. MULLARD Ltd. July 7, 1965 [April 7, 1964], No. 14390/64. Heading G1U. [Also in Division H3] A frequency-measuring apparatus, Fig. 3, comprises a pre-amplifier 10 connected to the input terminal 1, the output of the amplifier being applied to a mixer 11. Also applied to the mixer is the signal from an L. O. 13 having a linear sawtooth frequency/time characteristic. The output of the mixer 11 at an intermediate frequency selected by a band-pass filter 12 is supplied to a frequency discriminator 17 (see Division H3). The output of a discriminator 14 which improves the linearity of the L. O. 13 is also applied to a sawtooth generator 15 supplying the X plates of a calibrated C. R. T. 16 to provide a time base, the Y plates of the C. R. T. being supplied from the output of discriminator 17. The C.R.T. give a display similar to a pulse-compression response graph with a maximum corresponding to the frequency of the input signal. In a modification Fig. 4 (not shown) an additional filter 18 and amplifier 19 are provided and an A-scan display 16 is supplied via a wide-band video-amplifier 21. In another modification Fig. 5 (not shown) a doubleprobe system using reversed-polarity diodes replaces the single diode system of Fig. 2. In another arrangement Fig. (not shown) having an operating band from 8 to 12 Gc/Sec. and a sweep rate of 100 Kc/Sec. there are twenty probes and a backward wave oscillator 22 is swept over the frequency range by a waveform generator 23.

Title: Asphalt mixing plants for making asphalt paving mix
IPC: E01C19/10
Filed: 1973-03-27
Abstract: 1391039 Mixing apparatus K G OHLSON 27 March 1973 [28 March 1972] 14528/73 Heading B1C An asphalt mixing plant comprises means for supplying and heating mineral aggregate, means for supplying and heating a binder, a mixer for receiving the heated aggregate and binder, viscosity sensing and control means for sensing the viscosity of the heated binder and controlling the binder heating means in dependence thereon, and means for sensing the temperature of the binder in the binder supply means and for controlling the aggregate supplying and heating means in dependence on the sensed temperature. Bitumen is continuously circulated between tanks 29, 32 in which it is heated by heating means 30, 34, and is supplied therefrom to nozzles 27 in a mixer 23 by a pump 37. The viscosity of the circulating bitumen is measured by a viscosimeter 38, the signals from which are used to control the heaters 30, 34 by controls 35, 36. The temperature of the bitumen in tank 32 is also measured by temperature sensor 40 associated with control means 39; the latter provides control signals to thermostats 43, 37 which respectively control the heating means 41, 45 for different grades of aggregate held in bins 18, 20, 21 arranged to discharge (via a weighing hopper 22) to the mixer. The control means 39 is also connected to a thermostatic control 12 which is arranged to regulate the temperature of aggregate discharged from a rotary drum heater either by controlling the fuel supply to an oil burner 9 in the rotary heating drum or by controlling the feed rate of aggregate which is discharged from hoppers 1, 2, 3 to the heating drum. In use of the apparatus bitumen at the required viscosity is mixed in the mixer with the required quantity of the coarser grade of aggregate supplied at the controlled temperature. The finer grade or grades of aggregate are added subsequently at a lower controlled temperature. Finally filler material may be added, cold, from a hopper 24.

Abstract: 887,131. Automatic speed-control systems. WESTINGHOUSE ELECTRIC CORPORATION. April 26, 1960 [May 5, 1959], No. 14530/60. Class 38 (4). [Also in Group XXIII] A machine for lapping semi-conductor wafers comprises top and bottom lap plates 25, 26. Wafers 32 are contained in pockets 30 in work carriers 28 located between the lap plates and formed as planetary gears located between a sun gear 22 and a ring gear 24 driven, at differing speeds, by a shaft 20 driven through belt 18, gear-box 14 and coupling 16 by a squirrel-cage motor 12 within the housing of which is an eddy current coupling. To bring the shaft 20 up to speed slowly when starting the machine so as to minimize the danger of the wafers shattering, a coil 274 for the eddy current coupling can only be energized when a potentiometer 252 controlling excitation to the eddy current coupling has been placed in minimum speed position. A governor generator 288 connected to rotate with the output side of the eddy current coupling provides a tachometer feedback voltage which is rectified and compared with a control voltage resulting from rectifiers 290, 292 connected to the potentiometer 252, the voltage difference being modulated by grid control of the firing of the valve 286, thereby supplying the desired excitation to the coil 274 for the desired lapping speed.

Abstract: 683,598. Cathode-ray tubes. RAULAND CORPORATION. June 22, 1951 [June 23, 1950], No. 14878/51. Drawings to Specification. Class 39(i) An image reproducing cathode ray tube has a fluorescent screen formed on a glass viewing window and constructed to have low reflectivity in accordance with the principles set out in Specification 683,597, wherein both the inner and the outer surfaces of the window are formed with nodular protuberances, having a height of 5-10 microns and a diameter of 25-100 microns. Both surfaces of the window may be formed by any of the methods disclosed in Specification 683,596, [Group XX], and 683,597'as applied to the outer surface only and the fluorescent screen is formed as a coating on the inner surface thereof. For glass bulb tubes the reflectivity of the window is 0.5 to 2 per cent of that of a mirror surface and the nodules 5-10 microns in height and 25-100 microns in diameter. Since the window varies in thickness, being thicker at the edges than at the centre, the reflectivity is made higher than would be necessary at the centre to maintain acceptable definition over the whole picture. For metal cone' tubes the glass window is thinner and of more uniform thickness than in the glass bulb type and suitable parameters are a reflectivity of 0.5- 1.5 per cent of that of a mirror surface and nodule dimensions of 5-10 microns in height and 25-50 microns in diameter.
