Abstract: 868,250. Igniting gas burners. GAS COUNCIL. Feb. 6, 1958 [Nov. 21. 1956; May 7. 1957], Nos. 35651/56 and 14542/57. Class 75(3). A flash back ignition device for a gas burner, 23 comprises a substantially straight flash tube 42 of constant cross-section having a gas nipple 47 provided with two closely spaced orifices 48, 49 one of which directs a stream of gas along the flash tube to a permanent igniter, for instance a small gas jet or an electrically energized catalytic wire 5, and the other of which directs a flame through a side opening 46 in the flash tube towards the burner 23, the flows of gas to the nipple 47 and to the burner 23 being controlled by a single gas cock 13. Each of the four burners on the top plate of the gas oven shown has its own flash tube, double orifice nipple and igniter which are disposed on the outside of the vertical peripheral wall 37 of a well plate 36. The burners are disposed within the well plate and apertures 38 are provided in the wall 37 for the ignition flame from the double orifice nipples. The igniters may be mounted within the ends of the flash tube and instead of two igniters between the adjacent ends of two flash tubes (as shown) a single igniter may be provided. The electric igniters may be energized by a switch actuated by the gas cocks. The flash tube 44 associated with the oven burner 32 has a gas nipple having two orifices facing in opposite directions, one being directed along the flash tube to the igniter 50 and the other being directed out of the open end of the flash tube to impinge on a bimetal strip 35 which on heating opens a valve 34 to supply gas to the oven burner; the latter is then ignited by the flame heating the bimetal strip. A similar valve operated by a bimetal. strip may control the gas supply to each of the hot plate burners. The gas nipple in the flash tube may have three orifices, one directing gas to the igniter, another towards the bimetal strip and the third towards the burner. In a modification the four flash tubes for the hot plate burners and a flash tube for an oven burner terminate in a single control chamber disposed at the centre of the well plate 36 and containing a permanent pilot jet. Holes may be formed in the flash tubes near the control chamber. Baffles may be disposed in the flash tubes.

Title: Improvements in or relating to the treatment of spent alkali metal hydroxide reagentfrom caustic-alkali lead or lead alloy refining processes
IPC: C01D1/32
Filed: 1937-12-30
Abstract: Spent alkali metal hydroxide reagent from caustic alkali lead or lead-alloy refining processes is mixed with a limited amount of water to form a sludge and treated with calcium hydroxide at a temperature less than 80 DEG  C. and preferably at room temperature, the solid matter containing oxysalts of calcium being removed from the resulting liquor.  The limited amount of water is probably insufficient to permit sedimentation of metal prill in the sludge and preferably not substantially greater than that necessary to dissolve the free soda.  Metallic prill is removed together with the oxysalts and may be separated later.  The oxysalts may be smelted with charcoal, sand and fluorspar to recover the metal. The process is applicable to both caustic soda and caustic potash.ALSO:Spent alkali metal hydroxide reagent from caustic-alkali lead or lead alloy refining processes is mixed with a limited amount of water to form a sludge and treated with calcium hydroxide at a temperature less than 80 DEG  C. and preferably at room temperature, the solid matter containing oxysalts of calcium being removed from the resulting liquor.

Title: Magnetic recording and reproducing system
IPC: G11B15/52
Filed: 1973-07-30
Abstract: 1422206 Measuring speed electrically MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 30 July 1973 [2 Aug 1972 (2) 7 Aug 1972 13 Sept 1972 20 Feb 1973 (2) 9 May 1973] 36279/73 Heading G1N [Also in Division G3]  A speed control system for a magnetic tape drive system including means to record on and replay from the tape a signal so that the time interval between the recording and replaying instants is determined and the speed of the drive system controlled accordingly wherein there additionally is provided masking means to inhibit operation of the reproducing circuit for a period sufficient to allow leakage flux to decay. A combination head having a recording gap g 1  and a replaying gap g2 has a recording coil 15 connected to a recording circuit 24 and a replay coil connected to an amplifier 20 forming part of reproducing circuit 28. In operation pulses of current, (Fig. 4a,) flow through the recording coil and a reproduced as spike pulses by the replaying coil, (Fig. 4b). The reproduced pulses pass through the peak detection circuit 21 as narrow pulses, (Fig. 4c), and trigger a monostable circuit in mask circuit 22 to produce a pulse of predetermined duration, (Fig. 4d), long enough to mask any spurious pulse produced by flux leakage. This pulse passes to recording circuit 24 to charge the polarity of its output and to the level conversion circuit 25. A connection between the recording circuit 24 and peak detection circuit 21 ensures that circuit 21 only responds to pulses of opposite polarity to the recording pulse. The time between successive pulses from mask circuit 22 is used in level conversion circuit 25 to produce an output signal which is used in amplifier 26 and drive circuit 27 to control the speed of motor 3. In operation circuit 25 consists of a resettable sawtooth waveform generator whose output is connected to a capacitor through a switch closed momentarily by the mask circuit pulse output. The voltage across the capacitor passes to amplifier 26 to set the speed of the motor. To avoid loss of control caused by drop-outs on the tape the circuit 23 provides a pulse input to mask circuit 22 and to circuit 25 so that the capacitor voltage in circuit 25 remains unchanged until the next replayed pulse is detected The controlling circuit 31 responds to the input command signal at 29 to over-ride the control system and provide the motor with an initial starting current. The translucent leader on the tape is detected by the photo-electric sensing arrangement 9, 10 and circuit 30 provides supplies a signal to amplifier 26 to replace the signal generated by the recording head.  A modified recording head which is suitable for tape movements in both directions is disclosed Fig. 8 (not shown).

Title: Process for improving the odour, taste, and digestibility of raw yeast for the purpose of employing it as edible yeast
IPC: C12N1/06
Filed: 1920-12-31
Abstract: 156,153. Traun's Forschungslaboratorium Ges., H. O. March 15, 1919, [Convention date]. Yeast preparations.-To improve the taste of yeast and to render it more digestible, it is treated with hydrogen under heat and pressure. It may first be treated with a solution containing ammonium or sodium carbonate or borax and washed to remove the bitter flavour, and disintegrated in any known way. It is then treated with hydrogen at a pressure of 100-200 atmospheres and a temperature of 100-130‹ C. The liquid thus obtained may be used dried directly, or dialysed by electroosmosis or otherwise to remove salts. The action is facilitated by the presence of small quantities of sodium chloride, or organic acids such as formic, acetic, tartaric, or citric acid. The yeast may also be first reduced to a dry powder and treated with hydrogen in this state. Catalysts such as nickel or palladium may be employed in masses, but not as powder. Higher temperatures and lower pressures may be employed, in which case the yeast must be washed after treatment. The Specification as open to inspection under Sect. 91 (3) (a) states that the disintegrated yeast may be mixed with flats and oils and used without hydrogenation. This subject-matter does not appear in the Specification as accepted.
