Title: Improvements in electro-magnetically operated direction indicators for road vehicles
IPC: G08B5/28
Filed: 1927-06-30
Abstract: 275,948. Unterberg, G. Aug. 11, 1926, [Convention date]. Road-traffic signals on vehicles.-In signalling apparatus, for use on road vehicles, of the type in which an indicating pointer q is actuated by electromagnets a, b, the locking bolt o for the actuating lever p is released automatically after the vehicle has travelled a predetermined distance, whereupon the pointer returns to its normal position. When one of the switches r, s is depressed, the corresponding electromagnet a, b is energized to set the pointer q, and at the same time the coil c is energized through contact t and lead b in order to raise the locking bolt o. This latter circuit includes a coil d which, when energized; moves a core d<1> so as to bring a gear f into mesh with a constantly running gear g on a shaft v. The shaft may be driven from the odometer mechanism. After a predetermined distance has been run, a cam e on the shaft of the gear f allows a spring-influenced finger i to snap down and rock an arm k into contact with a member b. The circuit 9, 10 is thus completed to energize the coil c which lifts the locking bolt o and allows the pointer g to return to normal position. At the same time, a coil h is energized and attracts the core d<1> in order to bring the gear f out of mesh with the gear g,

Abstract: 982,992. Determining moisture content. CONTROLS CO. OF AMERICA. May 17, 1961 [May 26, 1960; July 26, 1960], No. 17967/61. Heading G1N. In a laundry drier the voltage drop across electrodes 66, 64 which are supplied with rectified A.C. through a resistor 48, rises as the clothes dry to trigger a switching diode 40 and effect energization of a relay B which opens the control circuit established by relay A in response to the momentary closing of switch 10 and interrupts drying. Push button insertable resistors 50, 52, 54, 56, 58, provide for obtaining different degrees of dryness and a capacitor 74 prevents false operation by momentary interruption of the circuit between the electrodes. A high value resistor may be connected in series with the electrodes to ensure eventual shut down when the wetness control resistors are cleared; and a second capacitor may be provided to be switched in parallel with capacitor 74 to provide further protection against false operation with small loads in the dryer. Alternative control by a timing circuit comprising a capacitor switched in place of the drum electrodes is described for controlling fluffing. Hot air may be blown through.

Title: Improvements in and relating to measuring apparatus
IPC: G01N27/12
Filed: 1954-06-18
Abstract: 754,039. Electric indicating systems. MINNEAPOLIS-HONEYWELL REGULATOR CO. June 18, 1954 [June 29, 1953; Oct. 30, 1953], No. 17969/54. Class 40(1) [Also in Groups XXXV and XXXVI] Apparatus for determining the carburizing potential inside a metal heat-treating furnace 10 (Fig. 1) comprises a thermocouple 11 of material capable of absorbing the active constituent exposed to the atmosphere inside the furnace, whose thermal potential, indicative of the concentration of the active constituent, is indicated on a meter 13, and which is associated with a valve 15 for controlling the rate of admission of fuel into the furnace. For a carburizing atmosphere the thermocouple is made of a ferrous alloy wire. For determining the hydrogen content of the atmosphere the thermocouple may be platinum or palladium wire, or platinum-platinum plus 10-13 per cent rhodium. For nitrogen content the wire may include tantalum, e.g. nickel-nickel plus tantalum. Thermocouple construction. A U-shaped wire 50 (Fig. 4) has one limb protected from the atmosphere by glass 53, covered with a metallic sleeve 54. When exposed to the furnace atmosphere the uncovered position of the wire changes, and a thermal EMF is devloped at the junction 56 which is proportional to the concentration of the active constituent of the atmosphere. The junction 56 may be undercut to minimize absorption of the atmosphere by the covered portion of the wire. Circuit arrangement. Two thermocouples 20, 21 (Fig. 2) of different materials, located inside the furnace 10, are connected in series opposition with a portion of the E M F of a battery 26. The difference voltage is amplified at 32 and causes a motor 33 to drive the slider of a potentiometer 29 associated with the battery 26 until the difference voltage is eliminated, the motor 33 also driving an indicator (not shown). To compensate for temperature variations a further thermocouple 35 is located inside the furnace but shielded from the atmosphere, its output being amplified at 38 to drive a motor 39 which positions the slider of a further potentiometer 28 associated with the battery 26. Only one exposed thermocouple may be used, and the temperature-compensating thermocouple 35 may be connected in series with the atmosphere-sensitive thermocouple. Specification 568,204 is referred to.

Title: Circuit arrangement for the undisturbed transmission and storage of electrical information signals at a remote control installation
IPC: G08C25/00
Filed: 1973-04-13
Abstract: 1388078 Selective signalling SPRECHER & SCHUH AG 13 April 1973 [5 May 1972] 18008/73 Heading G4H In an arrangement for remote control, a central station addresses a transmitter and a receiver and passes information signals received from the transmitter to a store at the receiver, signal-carrying conductors between the central station and the transmitter and receiver being terminated in their characteristic impedance, the central station comprising means whereby when the current intensity in any of the signalcarrying conductors falls outside a given range, power supply to the store and supply of the address and information signals are interrupted. Interruption of the address signals is by gating off supply of clock pulses to address counters, and interruption of the information signals is by gating off a "reading" pulse train normally sent to the receiver. Interruption of the power supply is by opening an electronic switch in the power supply line at the central station. The current intensity is monitored by connecting a respective differential amplifier across a resistor in series in each signal-carrying conductor, the two outputs of each amplifier being ORed to a pair of threshold detectors used in common. The outputs of these detectors are ORed to feed a monostable which controls the interruption so that the interruption ceases shortly after the out-of-limit condition ceases. If the interrupted period continues for too long, or such periods occupy too large a proportion of the time, due to repeated or continued out-oflimit conditions, an alarm is given, being actuated using a low-pass filter, a monostable and NANDs.

Abstract: 515,334. Gutta percha and balata compositions. DUNLOP RUBBER CO., Ltd., TWISS, D. F., and HALE, R. W. June 20, 1938, No. 18198. [Class 70] [Also in Group III] Non-adhesive compositions consisting substantially of deresinated gutta percha and/or balata and a minor proportion of rubber are made by forming a solution of the gutta percha and/or balata in a volatile organic solvent such as benzene and forming an emulsion by mixing into the solution an aqueous. dispersion of rubber. The mixing may be facilitated by the addition of a neutral organic liquid soluble in the solvent and miscible with water, e.g. alcohol, of acetic acid, glue, gelatine, or a soap, which may be formed from oleic acid present in the solution and an alkali such as ammonia in the dispersion. The dispersion, which may be natural latex or an emulsion of synthetic rubber such as polymerized butadiene or chlorobutadiene, may contain vulcanizing ingredients and may be vulcanized before or after mixing with the solution, the gutta percha remaining substantially unvulcanized. The composition may be applied as a coating, e.g. by spreading before evaporation of water and solvent, or may be dried and subsequently moulded under pressure. Belting, insulation, and play balls may be produced.
