Patent ES-343575-A1 (ES)
Title: Conveyance of material requiring hygienic disposal
IPC: B65F5/00
Filed: 1967-07-29
Abstract: An apparatus for collecting and conveying material such as garbage or soiled linen, comprises upright shoots 2, each having material entry doors 3, and a valve 4 normally closed to support the material in the shoot and openable to allow the material to pass into a suction duct 1 through which it is conveyed to a separation chamber 5. In a system for garbage, shown in Fig. 1, three air extraction pumps 12 are pneumatically coupled to the duct 1 through a fine filter chamber 11 and the separator chamber 5 which incorporates a coarse filter adjacent its upper end. A valve 4A at the upstream end of the duct 1 normally restricts the airflow into the duct such that a vacuum is maintained, but is opened prior to the opening of a valve 4, such that a high velocity air stream awaits the garbage and causes a high vacuum in the open shoot 2. The valve 4 is pivotally mounted and power operated to pneumatically seal off the duct 1 in its closed position and to locally admit air into the shoot and be scraped clean as it moves into its open position. In the embodiment of Figs. 7 and 7A (not shown), the valve plate rebounds in its open position to shake itself clean. The separator 5 comprises an inlet from the duct 1, below the coarse filter screen and an outlet for air above the screen, valves being provided at 8 and 9 so that the separator may be by-passed by the air. The by-pass is brought into operation when the separator is to be emptied by screw or scraper devices feeding an incinerator 6 on a container. Pressurized air is supplied via line 12D to the top of the separator during emptying, to clear the coarse filter. The fine filter chamber 11 includes a vibrating cloth screen through which air is drawn and from which dust is shaken on to an emptying valve in the chamber base. An interlocking system normally prevents the doors in the shoots from being opened when the shoot valve is open, but a pivoting hopper door, Fig. 16 (not shown) permits the entry of garbage into the shoot at any time. A spur 1c from the suction duct 1 may be provided to supply a system of vacuum points lE for domestic appliances. In a system for soiled bagged linen, Fig. 2 (not shown), the separator comprises a chamber into which the bags fall and from which the air is extracted, an airlock being provided to facilitate removal of the bags. Inwardly opening doors at the top of each shoot and restricted by-passes around the shoot valves facilitate a continuous reduced pressure in the system. Water injection may be provided for the system to prevent frictional electrostatic changing and abrasion of the bags. Each valve may be operated through a photo-electric device sensing the accumulation on top of the valve. In the embodiment of Fig. 3 (not shown), a garbage and soiled linen system are arranged in parallel to be coupled to a common suction source.

Patent ES-361697-A1 (ES)
Title: Ignition and fuel control circuit
IPC: F23Q1/06
Filed: 1968-12-20
Abstract: An ignition and fuel flow control circuit for burners comprises an igniter requiring a first operating voltage when no flame is present at the burner and a second, lower voltage in the presence of a flame, an electrically controlled fuel-flow valve arrangement requiring a first current to open it and a second, lower current to maintain it open, electrical control means such that the higher and lower voltages at the igniter produce, respectively, the higher and lower currents in the fuel-flow valve, and valve control means which reacts to the continued presence of the higher current in the valve by closing the valve, thereby interrupting fuel flow. As shown, the voltage pulses for arcing electrodes 10, 12 are supplied by a circuit containing capacitor 24, resistors 26, 28, silicon controlled rectifier 20 and primary 18 of transformer 16. Before ignition occurs, the higher voltage required to produce a spark results in a correspondingly high voltage at base 38 of transistor 34 and this base voltage, controllable by rheostat 44, allows sufficient current to flow through the transistor to open the fuel-flow valve which is operated by solenoid 32. In the presence of a flame at the burner, the required sparking voltage is lower, and the resulting lower current through the transistor is sufficient to maintain open the fuelflow valve. If the fuel fails to ignite, the continued higher current raises the temperature of heater 52, thereby causing thermally responsive switch 54 to open, and the resulting open circuit causes the fuel-flow valve to close. The lower current flowing when the burner is ignited is insufficient to open the circuit in this way. In another embodiment, solenoid 32 is replaced by a solenoid 56 (Fig. 2, not shown) wrapped around the closure element of a fuel valve. The valve is maintained open by the lower current, but in the event of ignition failure the resulting higher current increases the temperature in a heater (64) causing expansion of a bimetal which pushes the valve closure element back into its orifice, thereby shutting off the fuel flow. In a further embodiment, Fig. 3, thermal switch 72 is normally closed, so that as soon as the circuit is powered, the valve controlled by solenoid 68 is opened, whereas the valve controlled by solenoid 66, which is in series with valve 68, is only opened by the higher pre-ignition voltage. However, if ignition does not occur, the continued higher voltage causes a temperature rise in heater 70, resulting in the opening of thermal switch 72, thereby closing the valve operated by solenoid 68.
