Abstract: 1,178,109. Purifying combustion gases. COMBUSTION ENG. Inc. 3 Nov., 1966 [29 Dec., 1965], No. 49411/66. Heading B1R. Combustion gases from fuel-burning furnaces are purified by introducing into a hot zone of a furnace an additive capable of reacting with sulfur oxides, the combustion gases the additive and reaction products thereto being withdrawn and scrubbed with water. The additive may be alkali metal oxides, alkaline earth metal oxides or substances which produce alkaline earth metal oxides by thermal decomposite. Preferred additives are dolmite and/or limestone. When a ground solid fuel e.g. coal is being turned in the furnace an additive, e.g. dolmite, may be added to the coal before it is ground. Purified combustion gases leaving the scrubber may be related after leaving the scrubber by heat-exchange with gases entering the scrubber before discharge to the atmosphere.

Filed: 1975-12-03
Abstract: 1535216 Lamp testing SOUND DIFFUSION (Mfg) Ltd 3 Dec 1975 49591/75 Heading G1U [Also in Division H2] An emergency lighting assembly comprises a translucent housing of non-magnetic material containing an emergency lamp LP1, a storage battery charged by a mains supply, a light emitting diode LP2 for indicating normal operating conditions, and a test device including a normally closed reed switch RS-1 which is opened by placing a magnet on the housing thereby disconnecting the mains supply to enable the effectiveness of the lamp to be checked. When the mains supply is present, the battery is charged via a transformer T1 and diodes D1, D3. Transistors Q1, Q2 are maintained non-conductive so that the lamp LP1 is off but the light emitting diode is illuminated. If the mains fails, the transistors conduct and the lamp LP1 is illuminated by the battery, the light emitting diode being extinguished. To test the lamp LP1, a magnet is placed adjacent the reed switch RS-1 which opens to disconnect the mains supply and connect the lamp LP1 to the battery. The circuit may be constructed so that the lamp LP1 is also illuminated when the mains supply is present.

Title: Apparatus for converting light energy into electrical energy
IPC: H02S99/00
Filed: 1973-10-25
Abstract: 1445369 Pulse oscillators ROWENTAWERKE GmbH 25 Oct 1973 [28 Oct 1972] 49813/73 Heading H3T [Also in Division H2] A circuit for the conversion of light into electrical energy comprises a photo-electric transducer and means for storing the electrical energy converted by said transducer and a direct current transformer arranged to convert the stored energy into an alternating or intermittent voltage, a further photo-sensitive device being included to vary the frequency of a function of the light incident on said transducer. The loading of said circuit on said transducer is thus made optimum for varying levels of illuminations. Fig. 6 shows an oscillator comprising transistors 23, 24 having feedback via windings of transformer 213. The circuit is powered by voltage U1 derived by storing the output of photo-electric transducers (not shown) in a capacitor inductor. The frequency is reduced with increasing light level on the transducer by means of a photo-conductive resistor 18 3 . The output from secondary winding W2 is rectified to produce a higher voltage U2 which is stored in a capacitor or accumulator and may be used to power a lighter, clock, radio or measuring device. Fig. 4 (not shown) the photo-conductive resistor is used to control the frequency of a unijunction transistor oscillator which in turn determines the frequency of a switching transistor connected in series with the primary of the transformer. Fig. 7 (not shown) relates to a single transistor oscillator the frequency of which is varied by means of a further transistor in response to the voltage produced by a photo-voltaic cell illuminated by the same source of light as the main phototransducer. The photo-conductive resistor should have the same spectral characteristics as the photo-electric transducers, which characteristics may be changed by use of a grey filter.

Abstract: 1,077,872. Fluid alarm systems. SOCIETE D'ELECTRO-CHIMIE, D'ELECTRO METALLURGIE ET DES ACIERIES ELECTRIQUES D'UGINE. Dec. 20, 1963 [Jan. 5, 1963], No. 50534/63. Heading G4P. An alarm system employing fluid-switching devices has two phases of operation, in the first-which is initiated by the appearance of an alarm input signal-a first warning device (e.g. a buzzer) is operated continuously and a second warning device (e.g. a lamp) is operated intermittently, and in the second-which is initiated by manual operation of a control device and which continues until the alarm input signal ceases-the first warning device is not operated and the second warning device is operated continuously. In a preferred embodiment of the invention, Fig. 12, an alarm input signal D operates the first warning device K via an input device 14 and a gate 15, and starts an oscillator 22, 23, 24 via a gate 18, which causes intermittent operation of the second warning device V via an OR gate 19, 20, 21. Manual operation of a device R changes the state of a bi-stable circuit 16, 17 thereby inhibiting gate 15-thus stopping the first warning device K-and inhibiting gate 18-thus stopping the oscillator 22, 23, 24. The second warning device however is maintained operated by a signal from the bi-stable device 16, 17 via the OR gate 19, 20, 21. When the alarm input signal ceases the bi-stable device 16, 17 is restored to its normal condition and operation of the second warning device is stopped. The fluid elements, such as gate 15 and the like, can be pressure-operated ball valves (Figs. 3 and 4, not shown). In a modification (Fig. 13, not shown) the OR gate 19, 20, 21 is omitted and the oscillator 22, 23, 24 is so arranged that during the second phase it remains in a quasi-stable condition maintaining the steady operation of the second warning device. In both embodiments a manual test input T is provided.
