Title: Selecting Circuit for Display Panel.
IPC: G09G3/32
Filed: 1967-02-06
Abstract: 1,165,581. Display apparatus. RADIO CORPORATION OF AMERICA. 6 Feb., 1967 [15 Feb., 1966], No. 5664/67. Heading G5C. [Also in Divisions C4 and H3] A display apparatus, suitable for use with a television or data processing system, comprises a plurality of light emissive devices as shown in Fig. 1. The circuitry of each light cell in a row and its associated gate is shown in Fig. 2 which illustrates a light emissive device 20, suitably a luminescent diode of gallium arsenide, whose cathode is connected to a source and drain electrode 22 of a field effect transistor 21, the other electrode 23 of which is earthed. Gate electrode 24 is connected to one of the source and drain electrodes of a second similar transistor 26, the other of which is connected to a further transistor 29 which comprises one of the gates indicated in Fig. 1. The gate electrode 28 of transistor 26 is connected to the column scan generator of Fig. 1. In the embodiment shown, a plurality of light cells are arranged in rows and columns, particular light cells being selected by the co-operation of the column and row scan generators (Fig. 1). When control signal 33 from the row scan generator operates one of the row gates and signal 34 operates gate 28, signal waveform 35 is coupled to gate electrode 24 of output field effect transistor 21. Current proportional to the charge on the input capacitance C (represented by dotted lines) substantially equal to the amplitude of the image signal 35 flows from energy source 4 through light emitter 20 and the conduction path of transistor 21 to earth, and the capacitance C, having a storage time of the order of 1 second, can be made to store the signal information throughout a complete scan cycle whose period is somewhat less than this. The array of light emissive devices is not limited to the co-ordinate array illustrated in Fig. 1, but may also be a single column.

Title: Electrochemical apparatus
IPC: G01N27/36
Filed: 1964-02-11
Abstract: A glass electrode structure for measuring ion concentrations comprises in combination a membrane of ion sensitive glass, a metallic, electrically-conductive lead, and a solid, fused, crystalline electrolyte connecting one surface of the membrane with the lead.  A tubular stem 22 (Fig. 1, not shown) of a high-resistance glass is dipped into a molten bath of an ionsensitive glass and a thin bubble or membrane 20 thereof blown on the end of the stem.  A metallic, electrically conducting lead 24 is then held in the stem and partially extends into the bulb, and a molten mass of electrolytic material, e.g. silver chloride, is poured into the bulb between, and in intimate physical contact with, the lead and the inner surface of the bulb, and then cooled to crystallize. Alternatively the electrolyte 48 (Fig. 2, not shown) may be placed on the outer surface of the membrane 40 and the lead 50 wound round it, the whole being contained within a closed chamber 52 through which is circulated an insulating fluid. In a further embodiment, Fig. 3 (not shown), for forming micro-electrodes the lead 64, and electrolyte 62 are placed within a tube of ionsensitive glass 60 which is then heated to soften the glass and melt the electrolyte, the tube then being attenuated to give an end portion which tapers and has a suitably thin wall, but contains the lead embedded in the electrolyte 66. The ion sensitive glass may have the composition Na2O, 11.0%; Al2O3, 18.0%; SiO2, 71.0%. The lead metal is preferably silver but may be platinum or other noble metals. The electrolyte is preferably silver chloride although thallium salts may be used.

Abstract: 1448932 Automatic control of speed SANYO ELECTRIC CO Ltd 12 Feb 1974 [20 Feb 1973 13 March 1973] 06368/74 Heading G3R In apparatus for recording a video signal on a circular track, the speed of a motor driving the recording medium is controlled by the phase difference between a signal, whose period is an integer times the period of rotation of the motor, and a speed reference signal having a period equal to an integer times the horizontal synchronizing period of the video signal. As shown, the speed reference signal is obtained from an oscillator 18 via a frequency divider 21, and has a period in the range 260H to 270H (preferably 263H), where H is the horizontal synchronizing period of the video signal. The phase comparator 17, which can include a monostable multivibrator, a sawtooth generator and an FET see Fig. 3 (not shown), controls the speed of motor 12 driving a memory disc 11. The motor speed signal is obtained magnetically, using a detector with one or more rotating magnets. Single fields or frames of the input video signal at 1 are recorded by lead 8 on to the disc 11, and played back on a television connected to output 16. In other embodiments Figs. 5 and 6, (not shown) the speed reference signal is obtained by frequency division of the horizontal synchronizing signals that are separated from the input video signal.

Classes 100 (2) and 100 (4) A lettering press for stamping characters on book covers and other purposes with a coloured foil comprises a selectively rotatable type wheel 6 which is movable to effect stamping and which is mounted on a carrier 5 sliding on a base 1 extending transversely of the press and which is moved by a screwed shaft 8 to effect line or letter-spacing in one direction, and a platen 53 for supporting the cover &c. to be stamped which is displaceable to effect letter or linespacing in the other direction as the case may be. The base 1 is horizontally supported on a table 2 carried by a stand 3 and the edges of the base 1 are dovetailed to slidingly support the type carrier 5 having a depending lug 9 engaged by the screwed shaft 8 so that the carrier 5 may be moved for letter or line spacing according to the position of a book cover B. The platen 53 is mounted for line or letter spacing and has a guiding lug 54 sliding in a table groove 55 and the book cover B is held in position on the platen by a spring clamp 52 which is released by a pedal mechanism 56, 57, 58, 59, 59a, 59b, 60, 61. The carrier 5 having a pointer 51 is set into position by a capstan 10 and chain drive 12, 13, 14 and sprocket wheel 15 on the shaft 8 which is prevented from unintentional movement by a ratchet wheel 15a. The carrier may be returned by a hand crank 63 and gears 64, 65. The type wheel 6 is slidably mounted on dovetail grooves 5a on the carrier 5 and is moved to effect stamping by links 29, and lever 26 transversely slidable on a rod 25 operated by a pair of push rods 23 from a rod 22 linked to a pedal 18. The type wheel 6 is rotated into position by a handle 32a and is formed of three discs 32, 33, 34 bolted together, the central disc being slotted to accommodate the type T which are locked in place by grub screws in holes 36 in the disc 32. The disc 33 has a series of holes 37 in radial alignment with the slots for engagement with a nose 38 of a plunger 39, which is moved to lock the type wheel during the stamping process, by a roller 40 engaging a cam 41 on the carrier 5. In a modification, Fig. 6 (not shown), the type wheel comprises two discs octagonal in shape each edge of one disc having a slot to accommodate a line of type secured by an end screw, and a side plate, equal to the length of the line of type. The side plate is tightened against the type by flat spring and a thumb screw. The type may be heated by electrical resistance elements.
