Title: Method and apparatus for contacting finely divided material with a gas
IPC: B01J8/16
Filed: 1960-09-29
Abstract: <PICT:0916482/III/1> In a continuous method for contacting finely divided particles, e.g. starch, with a gas, e.g. anhydrous hydrogen chloride, a stream of the particles is conveyed through a confined contact space containing the gas and having an inlet and outlet arranged so that they are continuously filled with the particles to prevent escape of the gas.  Particles are fed from a belt 41 (Fig. 1) to a conveyer 10 having a floor 11 and sides 12, which is mounted on a carrier 13 vibrated by an eccentric 19, carrier 13 being supported on flexible struts 28.  The vibrations cause the particles M to flow from right to left, passing through a chamber 32 filled with gas supplied by diffuser 39.  The conveyer floor 11 has V-shaped transverse depressions 35 and 351 below end walls 34 and 341 forming an inlet 36 and an outlet 37.  The particles flow down into and up out of depressions 35 and 351 filling inlet 36 and outlet 37.  Dust formation at openings 36 and 37 is eliminated by flanges 38 and 381. The floor 11 has transverse protuberances 27 which mix the stream of particles to ensure uniform contact with the gas.  Carrier 13 is in the form of a channel and conducts material discharged from conveyer 10.ALSO:In a continuous method for contacting finely divided particles of starch with anhydrous hydrogen chloride, a stream of the particles is conveyed through a confined contact space containing the gas and having an inlet and outlet <PICT:0916482/IV(a)/1> arranged so that they are continuously filled with the particles to prevent escape of the gas.

Title: Improvements in focussing devices for roll-film cameras
IPC: G03B13/20
Filed: 1938-11-21
Abstract: 521,606. Photographic cameras. HOUGHTONBUTCHER MANUFACTURING CO., Ltd., and PARR, B. A. Nov. 21,1938, No. 33790. [Class 98 (i)] In a roll-film camera in which the portion of the film to be exposed bears on guide means located between the film spools, focusing means are provided which move the guide means relatively to the spools to and from the lens, which is fixed. The focusing means may be coupled to a range-finder. In the camera shown, in Figs. 2 and 3, flanged portions 29 of an apertured plate 30 extend over inturned walls 14 of the casing, and lugs 28, 29 extending upwardly and downwardly from these flanges carry rollers 22, 23 against which the film is pressed by a presser plate 24. Slots 34 and 41a in the lugs 28, 29 are respectively engaged by eccentric portions 33, 41 on shafts 32, 40, the plate 30 being thus held in position. To adjust the focus, the plate 30 is moved by rotation of 'the shafts 32, 40, the shaft 32 carrying a focusing knob 31 and an equal rotation being transmitted to the shaft 40 by a sliding member 37 having racks which engage gears on the ends of the two shafts. A short base split-image range finder is coupled to the focusing means, comprising a fixed mirror 60, through the upper unsilvered portion of which a direct view is seen, and a movable mirror 66 which reflects the lower half of the view to the mirror 60. The mirror 66 is carried by a bracket adjustably mounted on an arm 70 which is pivoted at 71 and carries on a plate 75 adjustably bolted to it a pin 79 engaging a cam surface 80 on a bell-crank lever 81. An arm 84 adjustably secured to the lever 81 engages by means of a spring 88 a pin 87 on one of the lugs 28 of the apertured plate 30. The focusing movement of the plate 30 therefore rocks the lever 81, and the cam 80 moves the arm 70 carrying 'the mirror 60. In a modification, the movable plate 30 is dispensed with, the film being held by a presser plate against rollers carried on eccentrically-mounted spindles which are simultaneously rotated to adjust the focus. Fig. 6, shows a further form, in which rotation of a ring 162 causes, through a pin and slot connection 163, 164, rotation of an annular screwed member 155, the resulting axial movement of which is given to an apertured plate 156 which bears against it, and against which the film is held by a presser plate 158.

Title: Positional information signalling apparatus
IPC: G03B15/00
Filed: 1974-07-31
Abstract: 1415829 Television FUJITSU Ltd 31 July 1974 [31 July 1973 (2)] 33892/74 Heading H4F [Also in Divisions G4 and G5] A pair (Li, Cj) of electrodes 1 is selected by altering the impedence between them, the digital position of their intersection being transmitted to a display 10 by means of the circuitry of Fig. 3 (which includes charge storage devices). As shown, lines L, C are separated by insulators and can be short-circuited by the conducting tip 4 of pen 3. Alternatively, the lines may be connected by pressure-, heat-, light- or magnetic - field - sensitive resistors, or reed switches, pen 3 being chosen accordingly. Display 10 may be a gas-discharge or electroluminesent display, or an array of light emitting diodes or liquid crystals. The circuity of Fig. 3 includes charge storage diodes D21, D22, D41, D42. When intersection (L1, C2) is selected the impedance therebetween is lowered and a voltage + Vc is connected to the path Q5-D41-D31-D12-D22-Q6. (by the timing signals of Fig. 4, not shown). Subsequently, transistors Q7, Q8, Q91, Q92 are turned on by further timing signals and charge storage diodes D41, D22 in which forward current has just flowed, conduct momentarily in the reverse direction so that electrodes (XI, Y2) of the display are supplied with voltages -Vw/2, +Vw/2 respectively. Vw is chosen to suit the type of display which, as described, a plasma display, and Vw is a write voltage which is chosen to be higher than a firing voltage needed to initiate a discharge, the discharge spot being subsequently maintained by a sustain voltage (alternatively, Vw may be an erase voltage). In the embodiment of Fig. 7, a film 23 is reproduced on the display PDP. The film is scanned by means 24-25 (there is no pen 3), light signals passing to the array 21 of electrodes L, C which are connected by light-sensitive resistors. Signals 22a, 22b pass via the circuitry of Fig. 3 to select the corresponding (X, Y) co-ordinates on display PDP. Alternatively, the whole of the film 23 may be irradiated at the same time and device 21 scanned electrically instead of optically. Various uses of the apparatus are described with reference to Figs. 8-11 (not shown), where a shape imposed on array I or 21 is copied on display 10 or PDP. The display scale may be enlarged or reduced, a map projection may be changed from stereographic to Mercator, and co-ordinates may be changed -from polar to Cartesian.

Title: Circuit arrangements for colour television receivers
IPC: H04N9/465
Filed: 1972-07-20
Abstract: 1428973 Colour television EMI Ltd 16 July 1973 [20 July 1972] 33919/72 Heading H4F The phase of operation of a PAL-switch 14 is controlled by the output of a phase comparator 16 receiving one input from the reference oscillator 7 and one input which is derived from the received "swinging" bursts but is of the same phase for all lines, phase comparator 16 producing an error signal if incorrect phase of operation of switch 14 is detected. In the embodiment shown in Fig. 1 oscillator 7 provides outputs on lines 12, 13, 10 of phases +(R - Y), -(R - Y), + (B - Y) respectively, the signals at the input and output of a oneline delay line 2 being fed via burst gates 8, 17 to a switch 15 operated at half line frequency in synchronism with PAL-switch 14, switch 15 thus passing to phase comparator 16 bursts of only one phase. If the switches 15, 16 are positioned as shown on reception of a line including a burst of +135 degree phase relative to + (B - Y) phase the output of phase comparator 16 maintains gate 18 closed to pass switching pulses 9 to switch 14, but if the switches 15, 16 are positioned as shown on reception of a line including a burst of - 135 degree phase relative to + (B - Y) phase the output of phase comparator 15 opens gate 18 so stopping the switching action of switches 14, 15. Phase comparator 16 then receives from switch 15 each received burst and provides an output to close gate 18, this process being repeated if necessary until switch 14 restarts in the correct phase. In an alternative embodiment (Fig. 3, not shown) the reference oscillator receives bursts alternately from the input and output of the one line delay line and operates at the phase of these bursts, i.e. at + 135 degree phase relative to +(B - Y) phase if the PAL-switch and the synchronously operated switch feeding the oscillator are operating correctly, the oscillator output being passed via respective phase shifters to the PAL switch and (B - Y) demodulator. The phase comparator receives the reference input to the (B - Y) demodulator and the bursts (of - (B - Y) phase) from the chrominance signal adder (22) feeding the (B - Y) demodulator, detection of incorrect operation causing an extra switching pulse to be applied to the PAL-switch.
