Title: Arrangement for the remote switching-on and initialization of a data terminal
IPC: G06F1/32
Filed: 1976-09-09
Abstract: 1517639 Automatic exchange systems, data transmission ING C OLIVETTI & C SpA 9 Sept 1976 [30 Sept 1975] 37441/76 Heading H4K A data terminal is connected to the power supply and initialized upon detection in a switch on control unit of ringing signals on a telephone line. The program controlled terminal 1 is coupled to a remote terminal 2 over a telephone line 17. The terminal has a console switch 10 which can be set to a position TLA to set the terminal to incoming calls. The state of the switch is stored in register in a program and data RAM 6. When the switch 10 is set to this position, logic in a switch control unit 4 is primed to respond to ringing signals, and in reponse thereto connects the power supply 5 of the terminal to the mains VAC, thereby initiating reading from a location in a ROM or PROM 8 the identity of the perpheral unit which stores the initialization program, the latter being transferred to the RAM 6. The peripheral to be used is specified in the ROM or PROM by the manufacturer. In a mode in which an operator is present the terminal may be arranged to display a LOAD request upon detection of a call requesting the operator to specify the peripheral to be used. A fault program which may be entered if for example the operator does not make a permitted response and an arrangement to cause switch off and no further response to incoming calls in the event of a low voltage supply are described. Data is received at the maximum rate that can be carried by the line and the terminal remains active after termination of the connection until printing or processing of the received data is complete. The terminal then returns to standby condition ready for the next call.

Title: Organsols containing colloidal carbon
Inventor: FITCH FREDERICK TROOP
IPC: C01G43/025
Filed: 1965-09-02
Abstract: The invention comprises organosols containing colloidal carbon and optionally a colloidal metal oxide, the colloidal particles having a surface coating of an organic carboxylic acid containing at least 5 carbon atoms.  The sol may be prepared by preparing a dispersion in a mixture of an organic liquid and water of colloidal carbon or of colloidal carbon and a colloidal metal oxide in which the colloidal particles are coated with the organic carboxylic acid in an amount of from 2.5/R to 5.6/R moles per mole of colloidal material, where R is the average radius of the colloidal particles in millimicrons; and removing water from the dispersion.  The dispersion can be prepared by mixing an organic liquid with a mixture prepared by mixing the organic carboxylic acid with an aqueous dispersion of colloidal carbon or of colloidal carbon and a colloidal metal oxide, or alternatively a carbon organosol prepared by the above method may be mixed with a mixture prepared by mixing an aquasol of a colloidal metal oxide with the organic carboxylic acid.  The dispersion may contain colloidal particles of actinide metal oxides e.g. urania and thoria or zirconia, alumina or rare earth metal oxides.  If the metal oxide is an antinide metal oxide the colloidal particles may be of a size from 20-50 millimicrons and the amount of acid may be from 0.12-0.28 moles/mole of colloidal material present.  The carboxylic acid is preferably benzoic acid but may also be straight chain fatty acids such as caproic, heptanoic, caprylic or decanoic acid, branched chain fatty acids such as isovaleric or isocaproic acid or phenyl derivatives of fatty acids such as a  phenyl propionic acid.  The organic liquid may be benzyl alcohol, carbon tetrachloride, furfural, tetrachloroethane, primary or secondary monohydric alcohols containing at least four carbon atoms, for example n-butanol, n-amylalcohol, n-hexanol, n-heptanol or n-octanol, branched chain alcohols such as 2-butanol, 2-pentanol or 2-octanol, benzene, ethers such as isopropyl ether and esters such as ethyl acetate.

Title: Oscillators
IPC: H03K4/52
Filed: 1974-08-07
Abstract: 1482407 Transistor sawtooth oscillator LUCAS ELECTRICAL CO Ltd 7 Aug 1974 [11 Aug 1973] 38159/73 Heading H3T An oscillator is connected to an external source of variable current (not shown) at terminal 13 which charges capacitor 14 to produce a variable rate of pulses, and a non-linear network which may be diodes 21, 22, 23, permits operation over a wider range of currents, the upper limit being increased. The capacitor is connected to the emitter of one transistor 15 whose collector drives the base of a second 17 connected with its emitter in the opposite sense to normal in order to reduce the gain. At a preset voltage the two transistors, which form a PNPN device, conduct regeneratively to discharge the capacitor and are thereby turned off, and the cycle repeats. The output waveform is taken from the terminal 13 via a shaping network 24 (not described). The rise in voltage at terminal 13 is said to be linear. Initially the diodes are off and the emitter of transistor 15 must go positive with respect to line 11 for conduction to start, and the diodes have no effect. Once the transistors are conducting and the capacitor has been partially discharged then the base of 15 is negative with respect to line 11 and the diodes form a non- linear load to reduce the loop gain of the PNPN device, thereby requiring a higher current to remain latched ON.

Title: Improvements in or relating to means for transmitting electric impulses
IPC: H03K3/37
Filed: 1928-12-27
Abstract: 328,549. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Dec. 27, 1928. Locating sounds.- Apparatus for transmit. ting controllable retarded electric impulses, for example, in electric signalling systems, depth sounding, and locating positions by sound, comprises a potential-impulsed resistance 1 in series with a glow discharge tube 2, a variable condenser 3 and secondary resistance 4 being connected in parallel therewith. A battery 5 and triode 6, or other adjustable resistance, are connected across the above paralleled circuits. The triode 6 is adjusted until relaxation oscillations cease and the tube just glows, there being a constant continuous-current flow across the tube in the absence of any impulse potential applied to the resistance 1.. If then an impulse potential applied reduces the voltage across the tube and the glow is extinguished, the condenser 3 builds up a voltage until the ignition point of the tube is again reached, the condenser thereupon discharging through the tube 2 and resistance 4. The time lag taken for this to occur may be varied by varying the capacity 3 or the resistance of the triode. The impulse potential may be in the direction tending to increase the current through the tube, but in this case it should be of a low value to prevent its simultaneous transmission across the resistance 4. A potential impulse in this direction lowers the voltage across the condenser 3 which is recharged from the tube and battery 5, the tube because of its small capacity being extinguished in the process.

Abstract: 976,577. Dish washing machines. TEMCO ELECTRONICS & MISSILES CO. Oct. 25, 1961 [Jan. 30, 1961], No. 38253/61. Heading A4F. [Also in Division H2] A dish washing machine comprises a washing compartment in which dishes &c. are loaded and washed, and a water heating chamber, which may also be used as a steam generator for final rinsing and heating of the dishes. In the embodiment described, Fig. 1, dishes 22 are mounted on racks 23 in the washing chamber 4. This washing chamber (Fig. 2) has a hinged door comprising the glass panel 29 held by the spring steel strip 30. Water for the heater enters through the pipe 79 and goes out through the drain 18. This has a small hole 20 at its lower end, to drain the washing chamber when no water is flowing in, and a large hole 19 at its top to provide an overflow when water is entering the chamber. Washing is effected by the rotating bar sprayer assembly 65. This consists of the bars 58, 59 rotating about the axis 57, within the housing 60. Water enters through the opening 67, the direction of ejection being changed by oscillating the housing 60 about the axis 57 by means of the reciprocating bar 66 and rotating wheel drive, 69. The heater and steam generator, 73 in Figs. 1 and 7, has an inlet 74 and an outlet 76 discharging into the pipe 79. It contains a heating element 97, and means for breaking the heating circuit when the whole vessel 73 overheats. The vessel 73 expands so as to separate the ends 104, 105 of the curved members 99, 103 and thus break the circuit 100, 101. In operation, the chamber 4 is loaded with dishes &c., and the door closed. The operations are then controlled by a cam operated time sequence. Solenoid valve 75 admits water to the heater 73 and hence to the washing chamber 4. After washing, the sprayer 65 is stopped and the valve 75 closed. Steam is then generated in 73 and blown into the chamber 4. This condenses on the plates &c. thus providing a distilled water rinse, and also heats them. When the chamber 4 is empty of water, an opening 47 under the door admits air to dry the dishes.
