Title: Methods and apparatus for cleaning reaction vessels
IPC: B01L99/00
Filed: 1981-01-28
Abstract: In automatic analysis apparatus in which photometric measurements are made through translucent wall portions of reaction vessels or cuvettes, there is provided a cuvette washing system for sequentially washing and testing the cleanliness of the reaction vessels or cuvettes. The cuvette washing system 10 comprises probes 22 depending from plate 24 which is associated with vertically movable plate 26. Oscillatable temperature measuring probe 40 may be included. Probes 22 are operable to evacuate each cuvette, to wash it, and to dispense into the washed cuvette a blank sample, when the optical characteristics are tested at the just completed test wavelength and compared with the stored results of that cuvette tested at the same test wavelength prior to the introduction of the sample and reaction fluids. If the vessel fails the comparison test, the analyzer will inhibit the use of the cuvette until it is cleaned again or until it has been replaced and passes the cleanliness test. Once the cuvette passes the comparison test at the old test wavelength, the cuvette is tested at the wavelength at which the next reaction in that particular cuvette will be tested and then the blank is removed and the cuvette dried by evacuating through a probe 22 in preparation for receiving the new sample and reaction fluids. The probes may have substantially the same outer configuration as the inside wall configuration of the cuvettes with the washing fluids flowing between the outsides of the probes and the inside walls of the cuvettes. <IMAGE>

Title: Digital-analogue converter circuit for speech-synthesizing electronic timepiece
IPC: G10L19/00
Filed: 1981-02-26
Abstract: A novel type of digital-to-analog converter circuit is disclosed for an electronic timepiece having a speech synthesizing capability. The converter circuit utilizes pulse width modulation to form a train of pulses in response to successive digital signals which specify amplitude and polarity values for synthesizing speech, with the pulse widths being determined in accordance with the digital signal values. By filtering out the unwanted high frequency components of this pulse train, speech signals can be synthesized through an audio transducer. Such a digital-to-analog converter is capable of operating in a satisfactory manner at low levels of supply voltage, and has a very low power consumption.

Title: Multi-zone process and reactor for cracking heavy hydrocarbon feeds
Inventor: MILLIGAN JOHN DAVID
IPC: C01B3/22
Filed: 1982-07-26
Abstract: In a multiple-zone fluidized bed conversion process and apparatus for producing light distillate liquid and fuel gas products from heavy hydrocarbon feedstocks, the feedstock is introduced into an upper fluidized bed cracking zone 14 maintained at a temperature of 482-760 DEG C (900-1400 DEG F) for cracking reactions, and resulting tars and coke are deposited on and within a particulate carrier material 17 therein. The carrier material descends through a stripping zone 18 to remove tars and then into a lower fluidized bed gasification zone 20, which is maintained at a temperature of 927-1093 DEG C (1700-2000 DEG F) by O2-containing gas and steam introduced therein at 22 to gasify the coke and produce a reducing gas. The stripping zone 18 contains coarse packing material 19 which is supported by a refractory annular- shaped grid 34. The decoked hot particulate carrier is recirculated by a transport gas supplied at 24, upwardly through a central refractory-lined conduit 28 to the upper bed. Such recycle of the carrier solids is controlled by a refractory-lined gas- cooled valve 50. <IMAGE>

Title: Laminated paper sheet
Inventor: MATSUMOTO KIYOSHI
IPC: B65H35/10
Filed: 1983-03-03
Abstract: Paper sheets (54) whose ends overlap are laminated in succession to a continuous plastics film (32), and then a gap is cut by cutter (76) in the laminated film, before the film is tensed in order to break the film at the cut gap. The film may be of polypropylene or PVC and is coated with a solvent based adhesive by rollers (34,36). The solvent is evaporated in an oven (52) before the film is pressed against the sheets by rollers (60,62,64). The laminate is stretched between sets of rollers (72,74) after the cutting action by virtue of their differing rotational speeds. Thereby, laminating operation of sheet paper can extremely be automated and the laminated sheet paper without any flaw can be assured. <IMAGE>
