Title: Improvement in kitchen stove or range
IPC: F24C5/00
Filed: 1927-04-20
Abstract: 294,499. Carpineti, A. April 20, 1927. Oil cooking-stoves; boilers, arrangements of. - A cooking-stove heated by petroleum burners comprises one or more series of ovens and a portion for heating cooking-vessels at one or both ends, the burners being disposed below the ovens and the chambers containing the cooking vessels. The stove shown, of which Fig. 2 is a longitudinal half section, comprises a back-to-back arrangement of two central combustion chambers 38, 39, heated by burners 10, 11, the gases from which pass below hot-plates 40 and around ovens 16, 17 at each side of each of the combustion chambers. At each end of the stove are four chambers 30, 31 containing cooking-vessels 52 and grouped around a central combustion chamber 2 heated by a burner 7. Dampers 20, 21, operated respectively by rack and pinion and pinion gears, control the passage of the gases round the ovens. Gases from the chamber 2 pass, under control of dampers 34, 35 to the chambers 30, 31, in which helical flues surround the cooking-vessels. A boiler 26 may be provided in an extension of the chamber 2, with a flue 27 leading through it to the chimney flue.

Title: Magnetic recording and reproducing systems
IPC: G11B21/10
Filed: 1974-03-11
Abstract: 1423931 Automatic control of position INTERNATIONAL BUSINESS MACHINES CORP 11 March 1974 [4 May 1973] 10701/74 Heading G3R A control system for positioning a transducer relative to a track on a record medium defined two adjacent guide recordings having alternate sections of differing magnetic form includes a second transducer co-operating with further recordings to provide a reference signal which is used to make the control system response substantially independent of variations in magnitude of signals detected by the first transducer. As shown in Fig. 1, the magnetic head 2 is aligned with the boundary line m between tracks V, W of oppositely alternating magnetic form and thus will transduce a mean signal of zero when aligned with line m, S 1 or S2 when deviating to the left or right respectively. The second magnetic head 3 co-operates with track V to produce a clockpulse signal whose amplitude will vary with the distance of the head from the record medium and is used in the circuit shown in Fig. 4 to alter the gain of amplifier 15 so that the magnitude of signals S1, S2 remains constant. The clockpulse signal is also used to control gate 8 so that a directional signal Œa can be applied to the alignment motor controller 16. The controller is also supplied with signal A which represents the magnitude of the deviation as derived from signal S1, S2 by rectifier 9. The system is particularly applicable to a magnetic disc store for positioning magnetic heads 4, 5 over data tracks on disc 20.

Abstract: 1,185,302. Valves. J. L. HALES. 10 March, 1967 [11 March, 1966], No. 10801/66. Heading F2V. [Also in Division F4] The supply pipe 34 to a water heater includes a variable head valve 23 connected across a stop valve 35 in the pipe 34 by inlet and outlet pipes 27, 33. The water enters at 27 a chamber 35 and flows to outlet 33 through perforations controlled by a tapered plug 29 connected to a loaded membrane 31, The maximum delivery pressure to the heater is determined by an open stand pipe 36, Fig. 4, downstream of the valve 23, the valve 29 being loaded to open at a pressure in outlet 33 slightly below that set by pipe 36. In operation valve 35 is closed and under static conditions the pressure in pipe 33 holds plug 29 closed. When water is drawn off from the heater, the drop in pressure in pipe 33 causes valve 29 to open.

Patent GB-1123871-A (GB)
Title: Production of chlorine dioxide
IPC: C01B11/02
Filed: 1966-03-11
Abstract: A process for producing ClO2 and Na2SO4 comprises reacting NaClO3 and a reducing agent in a generator zone in the presence of water and a quantity of sulphuric acid sufficient to establish in the generator zone an acid concentration greater than 4.3N, thereby generating gaseous ClO2 and providing an aqueous effluent containing sulphate ions and residual NaClO3 and reducing agent, passing said effluent to a crystallizing zone, introducing thereto a further quantity of NaClO3 and reducing agent which are reacted, in the presence of sulphuric acid, at an acid concentration less than 4.3N, thereby producing ClO2, withdrawing said ClO2 with water vapour under reduced pressure, thereby precipitating Na2SO4 which is removed from the crystallizing zone. Chlorine is generated simultaneously with ClO2. Preferably the process is conducted continuously by removing Na2SO4 crystals from the crystallizer liquor and returning the mother liquor to the generator zone, concentrated sulphuric acid being added to the generator zone to increase the acid concentration to the desired value. The crystallizer is operated at 5 to 350 (preferably 100 to 250) mm.  Hg and at or near the boiling point of the reaction mixture, ie., 20 to 80 (preferably 35 to 70)  DEG  C.  At above about 30 DEG  C. anhydrous Na2SO4 is precipitated: at lower temperatures hydrated Na2SO4 is obtained. The crystallizer is preferably operated at acid concentrations between 2.5 and 4.3N. The generator is operated at 20 to 70 (preferably 30 to 57)  DEG  C. and may be operated either at atmospheric pressure or at substantially crystallizer pressure.  It is preferred to maintain therein an acid concentration between 8 and 12N.  Chloride ion, in the form of sodium chloride or hydrochloric acid, is the preferred reducing agent: a convenient source of NaClO3/NaCl is chlorate cell liquor.  Chloride ion may be supplemented or replaced by other reducing agents, e.g. SO2, CH3OH, HCHO, HCO2H, added to the crystallizer.

Filed: 1973-03-07
Abstract: 1423235 Cameras ASAHI KOGAKU KOGYO KK 7 March 1973 [8 March 1972] 11102/73 Heading G2A  In a camera wherein-a main flash is preceded by a preparatory flash, the light reflected by the object during the preparatory flash is sensed, the preparatory flash is stopped when the light sensed reaches a predetermined value, the duration of the preparatory flash is detected and memorized and the duration of the main flash is controlled according to the memorized value. Preferably the duration of the main flash is arranged to equal that of the preparatory flash. As shown, for the preparatory flash a capacitor C s  is discharged through a tube FT1. The reflected light is detected by a photo silicon control element LASCR and a capacitor C 1  is charged at a rate dependent on the reflected light. When C 1  reaches a certain voltage it turns on element LASCR whereby a capacitor C 5  is discharged to fire a stop tube FT2. This causes a fall in the voltage on C s  which turns off a transistor TR2 and stops the charging of a memory capacitor C 2 . The voltage on C 2  thus indicates the duration of the preparatory flash. For the main flash a capacitor C m  is discharged through tube FT1 and simultaneously a switch S 7  is opened to initiate charging of a capacitor C 3 . When the voltage on C 3  exceeds that on C 2  an SCR is fired to trigger a stop tube FT3.
