Abstract: 957,246. Agglutinated fibrous fabrics. B. RUDLOFF. May 22,1962 [May 29,1961; Jan. 15,1962], No. 19595/62. Heading D1R. A non-woven fabric is produced by forming fibres into a layer; adding a quantity of powdered thermo-settable synthetic resin to the layer; break ing up said layer and forming the fibres therefrom into a web in which the fibres and the resin are uniformly distributed; subjecting this web to a current of hot air which passes therethrough to cause setting of the synthetic resin; further compressing the web whilst it is still hot; exposing the web to a current of cold air; and passing the web over a heated calender. Textile fibres, e.g jute, kapok, cotton, rayon or nylon, in flock or teased form, are disposed on a conveyer 2 by a device 1 and powdered synthetic resin is added thereto by a fluted rotary feed cylinder 4 provided in a device 3. The fibres are sucked into an enclosure 5 by a blower 6 connected to two perforated drums 7, 7<SP>1</SP> and are entrained on the steel points of a drum 8 to divide them and on passing between the drums 7, 7<SP>1</SP> form a web. The web is compacted by cylinders 9, the pressure between each of which is regulable. The web is conveyed through a tunnel 11 between two endless conveyers 10, 25 comprising steel wire lattices. Rollers 27 guiding the lower run of the conveyer 25 are mounted on a crossmember adjustable to the desired thickness of the web and a tension device 28 is also provided. Air passes through a filter 13, through a heater 12 in which it is heated to 200-220C., through a conduit 14 into cones 15 shielded by sheet metal strips, through the web to effect polymerization of the resin and into cones 15<SP>1</SP> for recirculation. The web is consolidated by rollers 17 which may be fluted to produce a goffered surface on the web, the upper rollers 17 being mounted on the same cross-member as the rollers 27. The web passes through a tunnel 18 and is permeated by cold air blown through cones 20 into cones 20<SP>1</SP>. Also, in the tunnel 18 the web may be humidified and have fireproofing and germicidal agents added thereto. A calender 21 having smooth heated cylinders or rings on the cylinder surfaces to obtain a smooth or goffered web surface is provided. The web is cut into sheets by a guillotine 22.

Filed: 1973-04-25
Abstract: 1435561 Analysis television V D KOZLOW and I Y BREIDO 25 April 1973 19690/73 Heading H4F In an arrangement for determining a spatial analysis of the distribution of a photoparametric characteristic, a photo-electric sensor 2 is disposed across the path of light rays coming from a luminous signal source 1 to produce video signals indicative of said characteristic, the video signal being analysed (at 4) as to whether or not it has attained a threshold and the above threshold parts (if any) being passed to a visual indicator 5, the luminous signal source 1 on the sensor and the visual indicator 5 having synchronized raster scans whereby the spatial distribution of the characteristic achieving the threshold is correctly displayed by the visual indicator. The threshold is successively changed in synchronism with the frames of the raster scans, such that the spatial distributions of different values of the charasteristic are successively displayed. In the arrangement of Fig. 2 the uniformity of light emission of a CRT 9 is investigated, using a photomultiplier detector 2, a CRT display tube 11, an analysing circuit 4 involving a threshold comparison and a threshold voltage generator 12 producing a staircase waveform, the two CRT's and the threshold generator 12 being synchronized at 6, 8. Assuming the CRT 9 to give off light uniformly, a film, e.g. X-ray film, may be placed in between the CRT 9 and photomultiplier 2 for spatial analysis as above (Fig. 6, not shown). Again assuming the CRT 9 to give of light uniformly, the spatial distribution of the sensitivity of the target of the photomultiplier 2 may be investigated (Fig. 7, not shown). If the photo-electric sensor becomes a television camera tube (assumed uniform sensitivity) the uniformity of brightness of a airing screen &c., may be investigated (Fig. 5, not shown). The circuitry details of the analysis and threshold means, 3 are given in considerable extent.

Abstract: 998,476. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. May 22, 1962, No. 19704/62. Heading A2C. A method of selectively separating undesirable components from shredded tobacco comprises continuously showering a stream of tobacco into an air stream of such velocity that tobacco shreds are entrained by the air stream and conveyed therewith while relatively heavier undesirable components are permitted to fall through the air stream. Tobacco is fed from a hopper 1 by a belt 2 to a carded drum 3 from which surplus tobacco is removed by a rotary rake 21, and carded drum 5. A picker roller 4 removes tobacco from the drum 3 and throws it past guide 18 between a smooth cylinder 6 and a blower drum 7. The drum 7 includes a fixed shaft 8, to which air is supplied, having orifices which co-operate with orifices 36 in the drum 7. The orifices 36 are shielded in the region of the drums 3 and 4. An adjustable air deflector plate 17 is also provided beneath the drum 7. The tobacco is thus blown on to a conveyer 19 from which it is delivered to conventional cigarette rod forming mechanism. The undesired components of the tobacco fall between the drum 7 and conveyer 19 into a tray 23. An adjustable baffle plate 22 may also be provided adjacent the conveyer 19. The conveyer 19 forms the bottom of a duct 29 from which air is removed by a suction pipe 33 which sucks the air and any dust particles from the duct 29 through a perforated wall 30.

IPC: H04B10/00
Filed: 1970-04-27
Abstract: 1,269,289. Photo-electric current measurement. TRANSFORMATEURS DE MESURE WALTER. April 27, 1970 [April 25, 1969], No.20128/70. Headings G1A and G1U. The current in a high voltage line is measured by use of a magnetic field responsive polarizing device which rotates the plane of polarization of a modulated light beam before it is detected and demodulated to indicate the current. As shown luminescent diode 10 is energized by oscillator 20 having a frequency of 20 KHz and the light output passes through polarizer 11 and is reflected by mirror 12 along axis A where it passes through two magnetic field responsive polarizing elements 21, 22 having windings 21A, 22A respectively. Winding 22A carries a current proportional to the A.C. line current which is to be measured and thus the rotation of the plane of polarization of the light beam is modulated at 50Hz. The top of element 22 is made reflective (see Specification 1,264,588) so that the beam passes back through elements 22, 21, mirror 12 to beam-splitting mirror 13 to photo-transistors 15, 17 through polarizers 14, 16 respectively. The electrical signals pass to differential amplifier 18 where they are amplified and filtered, and thus to demodulator 19. The output of demodulator 19 supplies amplifier 23 which energizes winding 21A to produce an equal and opposite rotation of the plane of polarization to that produced in element 22 so that the current in winding 21A is proportional to the line current. In modifications an astatic system (see Specification 1,207,540) is formed by providing a beam-splitting prism to direct light on to two mirrors each of which reflects the light along a path like the one shown. The returned light in each path is detected in a single photo-detector, Fig. 2 (not shown). Further modifications include the use of two light sources or semi-transparent mirrors with a single light source, Figs. 3 and 4 (not shown). A further modification uses a single light source to illuminate two channels in series, Fig. 5 (not shown). These two channel systems may be balanced by providing a circuit, Fig. 6 (not shown) which detects the unbalance of the channels and injects a modulated voltage into one of the inputs of amplifier 18.

Title: Improvements in and relating to the treatment of polyethylene terephthalate surfaces
Inventor: GATES WILLIAM ELLIOT FREW
IPC: C08J7/12
Filed: 1955-07-13
Abstract: The bonding properties of polyethylene terephthalate surfaces, e.g. for printing ink, are improved by exposure to ozone while maintaining the surface at a temperature of not less than 150 DEG  C. Ozonized air suitable for the treatment preferably contains between 3 and 8 per cent of ozone and may be prepared by exposing dry air or oxygen to a silent electric discharge.  Polyethylene terephthalate films may be treated, and these may be in an undrawn state or drawn to produce orientation or drawn and subsequently heat-set.  If the film has been drawn but not heat-set, the treatment may be combined with the heat-setting process, the applied heat being used both to set the film in the oriented condition and to bring about reaction of the ozone with the film surface.

Abstract: 851,245. Speed governors. NORTH THAMES GAS BOARD. July 9, 1959 [June 25, 1958], No. 20341/58. Class 57. [Also in Group XXIX] The flow of gas through a gas meter is controlled at a constant rate by having a shaft 10, which rotates at a speed proportional to the flow of gas through the meter, so coupled to the shaft 16 of a constant speed or synchronous electric motor 15 that it is prevented from rotating at a speed in excess of that of the motor shaft, the latter shaft being free to rotate independently of the meter shaft. The shaft 10, which is connected to the rotating drum of a wet gas meter, is provided with a crank 13 having a crank-pin 14 engaging with a spring-loaded detent 20 pivotally mounted on a crank-pin 17 secured to the motor shaft 16. In operation, the gas-pressure feed into the meter is arranged to rotate the meter shaft 10 at a speed faster than that of the motor shaft but, due to the contact of the pin 14 with the detent 20, the speed of the shaft 10 is braked by the motor 15 thereby governing the speed of the meter shaft, and consequently, the flow of gas through the meter, to the desired constant amount; a flow indicator 22 may be mounted on the meter casing and coupled to the shaft 10 by a chain-and-sprocket drive 12, 24, 25. The pivoted and spring-loaded arrangement of the detent 20 permits, if required, the motor shaft to be rotated when the meter shaft 10 is stationary; in an alternative arrangement the coupling between the latter two shafts may be in the form of a claw-type clutch.
