Abstract: 1,251,979. Multi-colour electro-photographic process. RICOH K. K. Oct.30, 1968 [Oct. 31, 1967], No. 51524/68. Heading G2H. Multi-colour electro-photographs are made by subjecting a photo-conductive surface to at least three successive treatments each comprising i) uniformly charging said surface, ii) exposing said surface imagewise to a colour component of the multi-colour image to be reproduced, the colour component being different in each treatment, to form a latent image and iii) developing said latent image by applying a liquid developer of a colour selected according to the colour component used to form the latent image, the said liquid developer comprising or dispersion in a hydrocarbon carrier liquid of resistivity at least 10<SP>9</SP> ohm. cm. and dielectric constant not greater than 3 of a toner composed of pigment particles coated with a polarity control resin which is an acrylic, methacrylic, acrylate or methacrylate polymer, the liquid developers used in the said three or more successive treatments being used in the order of increasing solubility of the toner polarity control resin in the carrier liquid. Such an order of use reduces the tendency of a later developer in the successive treatments to remove pigment from an already-developed image. The liquid developers preferably number four, having the colours red, blue, black and yellow and being used in that order. Toner polarity control resins specified include polylsutyl methacrylate, the copolymers butyl methacrylate/styrene, lauryl methacrylate/styrene and lauryl methacrylate/ hydroxyethyl methacrylate and terpolymers of styrene/hydroxyethyl methacrylate/lauryl methacrylate. Conventional hydrocarbon carrier liquids of the naphtha type are used.

Abstract: 1,265,911. Teaching machines. J. W. HANNAH. 3 Feb., 1970, No. 5173/70. Heading G5G. In a question-and-answer type teaching machine, optical projection means 8, 9, 10, 11 present a visible display on a screen 12, Fig. 2, the display consisting of a representation of material recorded in a single frame of a film which contains a plurality of such frames in an array of rows and columns such that each frame is identified by corresponding X-Y coordinates. In use the film is fitted in a holder 5 and at any one time only one of the frames 15, Fig. 5, overlies an aperture 7, Fig. 2, in the optical path of the projection means. The associated circuitry of Fig. 5 controls operation of X and Y motors 27, 28 for moving the holder 5 with respect to the aperture 7. Each frame presents the user with a multi-choice question to which he responds by depressing one of the switches 3 (Fig. 2). This action generates a coded signal which is temporarily stored in registers 17. Adjacent each frame 15 of the film is an area 16 bearing code marks which define the X-Y co-ordinate addresses of as many different frames as there are possible answers to the question posed (in the case illustrated, three). The user's selected answer is compared with the film's coded " answers " in comparators 47, the comparison establishing which answer was given and, in consequence, which other frame of the film should next be presented. The X and Y motors, which start running when the user releases his selection switch, are arranged to stop when coincidence occurs between the coded address of the next frame as determined by the above described comparison and code markings on strips 43 and 44 which move, with the holder 5, past photocell sensors 45 and 46. The motors stop automatically when the required frame is over the aperture 7 of Fig. 2. Fig. 6 (not shown) depicts an alternative control mechanism to that of Fig. 5, the principal differences being that retractible stops (53), electromagnetically operated to pass through apertures in the base-plate 6 of Fig. 2, are moved through these apertures whenever the user makes a selection. Only some of the stops, depending on the frame next to be shown, are moved at any one time and the moved stops constitute barriers to X and Y movement of the holder 5 beyond a certain point. The holder is moved to one corner of the film with all stops retracted, the appropriate stops are then moved into their operative positions and the holder is then moved generally diagonally of the film until it engages both X and Y sets of stops. The drive means is a single motor which stalls as soon as both sets of stops are engaged.

Abstract: 1296838 Starting prime movers JOSEPH LUCAS (INDUSTRIES) Ltd 9 April 1970 [27 May 1969] 26638/69 Heading H2H Apparatus for starting a prime mover is arranged so that a second attempt to start the prime mover should a first attempt be unsuccessful can only be made a predetermined time after the first attempt has been made. Movement of an ignition switch 12 to a starting contact 14 energizes a relay 16 by way of a normally closed contact 15a of a second relay 15. Energization of the relay 16 closes a contact 16a which causes a starter solenoid 17 to be energized; completes a self-holding circuit for the relay 16 by way of a diode 18 and causes a capacitor 23 to charge by way of a diode 19. When the capacitor 23 is charged sufficiently it renders a transistor 21 conductive to energize a second relay 15 which opens contact 15a, the relay 16 remaining energized by virtue of the self-holding contact 16a. Should the ignition switch 12 now be released from the contact 14 a further attempt to start the prime mover cannot be effect since the capacitor 23 will maintain the relay 15 energized and contact 15a open until the capacitor has become discharged to a point where it cannot maintain the contact 15a open.

As describedsuch filters are arranged in three columns each traversed by a light beam, and groups of three filters, one in each column, are discharged in succession. Each group is controlled by a motor driving a row of cams which close switches to operate solenoids controlling the pumps of slurry and hydraulic fluid, jacks to move and shake the filter elements and valves supplying blast air to remove the cake. The three photoelectric cells operate respective relays which control a common relay to feed a signal to all the group control circuits whenever all three beams are interrupted within a short period. The group control circuits include relay contacts which pass such signals only while the corresponding filter elements are in the lowered position and also include limit switches recording the return of the elements to their raised positions. If the cake discharge signal is not received and/or if the elements do not all return thereafter, lamps which normally indicate the element positions are caused to flash and the solenoid which normally starts the slurry pump following element return is automatically prevented from doing so.
