Abstract: 515,503. Coke ovens. PUENING, F. June 3, 1938, No. 16767. [Classes 51 (i) and 51 (ii)] In a coke oven having hollow internally-fired movable heating-walls which can be spread apart to facilitate discharge of the coke, the heating-burners deliver through both the narrow ends of the heating-walls. In the arrangement shown horizontal inter-digitated baffles 37 form a sinuous flue through which the heating-gases flow upwards, and adjacent flue sections 38 are fired from opposite ends by burners 40 which project so far into the flues that the flame will be surrounded by a blanket of combustion products from the flue beneath. The two top flues 38B, 38C have no burners, and the products of combustion from the uppermost fired flue 38A are withdrawn by a fan 41 through openings 46 and are passed to the flues 38B and 38C, part being exhausted thence to atmosphere through the offtake 50 on the opposite side to the fan, and part being returned to the lowermost flue for recirculation through vertical pipes 51, 52, 53. A connection 47 allows gases from the flue 38A to pass to the upper side of the fan, and a bye-pass controlled by a damper 54 is provided to relieve the load on the fan when starting up. Circulation may be effected by an exterior fan as described in Specification 487,150. The broad faces of the heating-walls may be vertically ribbed, and the short connections between the flues formed by these ribs may be damper-controlled. Specifications 515,502, is referred to.

Title: Ink recording apparatus
IPC: H04N1/034
Filed: 1976-04-26
Abstract: 1491848 Ink jets INTERNATIONAL BUSINESS MACHINES CORP 26 April 1976 [12 May 1975] 16816/76 Heading B6P An aerosol ink jet is produced by passing a carrier gas through an ink nebulizer 14 to an aerosol chamber 12. The aerosol exits via a passage 22. As a result of entering the passage 22 the ink in the aerosol is confined to the centre of the jet 26 and is surrounded by a carrier gas stream 28 and produces a printing line width smaller than the diameter of the passage 22. As shown the jet is selectively switched on/off by closing/opening of the valve 76. With the valve open the vacuum source 74 is unable to attract the air from supply 84 across the passage 22 to disrupt the aerosol jet. The vacuum source 74 also draws guttered ink through the porous block 20. Alternatively the jet can be switched, Fig. 6 (not shown) by having only one air supply on the opposite side of the passage to the vacuum source and switching the air supply on/off. Other alternatives. Fig. 4, 5 (not shown) use a transducer to produce turbulence in the jet so that the ink jet has insufficient velocity to wet the recording paper 30.

Title: Audio frequency signal changing circuits
IPC: H03G5/02
Filed: 1972-08-08
Abstract: 1410772 Stereophonic systems NIPPON COLUMBIA KK 8 Aug 1972 [11 Aug 1971 30 Nov 1971 14 April 1972 25 May 1972] 17062/75 Headings,H4R and H4J An audio frequency signal charging circuit substantially cancels from. a pair of stereophonically related first audio frequency input signals respective substantially identical components of the two signals which are of the same phase and level and which occupy a band within the first signals. The remaining signals are mixed with a second audio frequency input signal which has a frequency range occupying at least part of the band. Stereophonically related input signals 1L, 1R (Fig. 1) are applied to phase splitters 47L, 47R to provide outputs of opposite phase. Outputs (-) of one phase from the phase splitters 47L and 47R are directly applied to adders 48L and 48R and outputs (+) of opposite phase are also fed to the adders 48R and 48L through respective phase shifters 49L and 49R having a voice frequency band width. When a microphone 6 is operated and switch in by a switch (S), Fig. 4 (not shown), centrally located vocal sounds in the stereophonic image are removed from signals 1L, 1R by virtue of phase shifters 49L, 49R while voice frequency signals from the microphone 6 are superimposed on the remainder of the signals 1L, 1R. In an alternative arrangement, switching is performed by a switching circuit in each channel, comprising a F.E.T. 53L, 53R (Fig. 5), the gate of which is supplied with a drive signal when the microphone 6 is used. The output of microphone 6 is amplified by an amplifier 7, envelope detected by a detector 21e, shaped by a waveform shaping circuit 22e and applied to each F.E.T. gate. The circuit operates such that when the microphone 6 is not in use the resistance between the source and drain of each F.E.T. is low and the signals from phase shifters 49L, 49R are cut off. When a voice frequency signal is applied to the microphone, a corresponding operating signal is applied to the gate of each F.E.T. to render the phase shifters 49L, 49R operative. Only a centrally located sound signal in the voice frequency range is removed or suppressed from the stereophonically related signals 1L, 1R when the phase shifters 49L, 49R are operative.
